AB  - Imaging of biological processes are of the great importance for early diagnostic of diseases and for understanding the disease pathway in the human body [1]. In order to improve image contrast and resolution, different optical fluorescent probes, such as florescent dyes, fluorescent proteins and quantum dots, have been developed. However, their application is somewhat restricted by photobleaching, cell autofluorescence, and small tissue penetration depth [2]. Lanthanide doped up-conversion nanoparticles (UCNPs) owing to their unique optical properties and high photochemical stability, represents a promising material for superior optical diagnostic and drug delivery systems [3]. Due to large anti-Stocks shift, UCNPs have converse excitation and emission profiles: under excitation by near-infrared light (NIR), they are able to emit visible or UV photons whit a shorter wavelength [4,5]. Hexagonal-phase NaYF4:Yb,Er nanocrystals are the best NIR-to-visible up-converting materials to date, but YF3 phase due to its wider optical transmission window, and the minimization of the excited state quenching of doped ions, is considered to be promising material for application in biolabeling as well. In this work, biocompatible YF3:YbEr and GdF3:YbEr mesocrystals were prepared by one-pot solvothermal synthesis in the presence of chitosan, and are used successfully as biolabeling agents. The crystallinity and phase purity of the obtained powders were confirmed by X-ray powder diffraction which revealed that both samples are with the orthorhombic Pnma crystal structure, and monophase. Homogeneous distribution of dopant ions in the host matrix was confirmed by STEM/EDS mapping (not shown). SEM and TEM analysis implied that particles possess morphology similar to the unshelled peanuts, which are built from smaller monocrystals (Figs 1a and b). It was shown that their capacity toward self-organization is determined by the amount of surface-preserved chitosan ligands, which presence is confirmed by FTIR spectroscopy. Chitosan presence provides biocompatibility, thus the viability of both, MRC- 5 lung fibroblast, and A549 lung carcinoma cells was highly preserved (>80%), after 24 h of incubation with the synthetized samples (50μg mL-1). To monitor the intracellular uptake, cells incubated with particles were further analyzed by laser scanning microscopy under 980nm excitation. A strong up-conversion emission (green spots at Figs 1c and d), indicated that particles (green spots) are positioned in the cells cytoplasmic area adjacent to the plasma membrane, in both cell lines. Such positioning, without disturbing cells nuclei confirms their capacity to be used as NIR cell labeling agents.

AB  - Owing to its high energy density and environmentally friendly properties, hydrogen is recognized as promising fuels in the future energy system. Among the various techniques for H2 production, electrochemical water splitting, concerning both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), is established as an efficient one. However, the kinetics of electrocatalytic water splitting reaction is significantly slowed down by the large energy barriers of the two-electron transfer (HER) and four-electron-proton coupled reaction (OER) pathways. The sluggish kinetics of water splitting processes can be overcome by employing electrocatalysts. It has been shown that Pt-based electrocatalysts exhibit the best HER activity, while IrO2 and RuO2-based electrocatalysts demonstrate the best OER activity [1,2]. Though, scarcity of noble metals and high price hindered their commercial applications in water splitting. Hence, it is an imperative to replace noble metal-based catalysts or reduce their amount through combination with abundant materials. The aim of this study was to examine an influence of ZnO to RuO2 mass ratio in the ZnO/RuO2 composites on their structural properties in order to prepare commercially acceptable materials with an enhanced photo(electro)-catalytic activity for water splitting. Composites of ZnO and RuO2 with mass ratios of 1:1, 2:1 and 10:1, named 1ZnO/1RuO2, 2ZnO/1RuO2, 10ZnO/1RuO2, respectively, were synthesized using the microwave processing. The structural investigations of the composites were completed using TEM/HRTEM and ADF/STEM analysis, including EDXS elemental mapping (FEI Talos F200X microscope operating at 200 kV, Thermo Fisher Scientific, Waltham, MA, United States). The electrocatalytic (EC) activity of the prepared composites towards OER and HER was examined through linear sweep voltammetry (LSV) in both acidic (0.1 M H2SO4, pH ∼ 1) and alkaline (0.1 M NaOH, pH ∼ 13) electrolytes. An Ivium VertexOne potentiostat/galvanostat and a conventional three-electrode quartz cell setup, including a glassy carbon as the working electrode, a platinum foil as the counter electrode, and a saturated calomel electrode as the reference electrode, were used for the EC measurements. The working electrode, with a surface area of 0.3 cm2, was coated with a catalyst ink prepared by previously published procedure [3]. The results of TEM analysis, Figure 1 (a-c), show that 2ZnO/1RuO2 composite is consisted of the smallest particles which are uniform in size and shape, while the both decreases of ZnO content (in 1ZnO/1RuO2 composite) and its increases (in 10ZnO/1RuO2) provoke appearance of larger, irregularly shaped particles. Besides, EDXS elemental mapping reveals that 2ZnO/1RuO2 composite possesses particles with the most homogeneous distribution of all constituting elements, Figure 1 (d-f). Figure 2 shows LSV curves illustrating the HER/OER catalytic performance of ZnO/RuO2 composites in a (a) 0.1 M H2SO4, and (b) 0.1 M NaOH electrolyte solutions. Solid lines represent LSV results obtained under dark conditions while dashed lines represent LSV results obtained after 60 minutes of simulated solar-light illumination. As can be seen from Figure 2, the 2ZnO/1RuO2 composite demonstrated superior HER/OER photo(electro)-catalytic activity in both electrolytes. Comprehensive structural analysis completed with Raman, PL and UV-Vis DR spectra indicates that superior HER/OER photo(electro)-catalytic activity of the 2ZnO/1RuO2 composite can be attributed to an optimal amount of oxygen vacancies in its crystal structure and homogeneous distribution of all constituting elements in the particles.

AB  - Rare-earth (RE)-based materials are particularly interesting since they possess exceptional optical, electronic, and magnetic properties. These materials consist of a host (matrix) that can be doped with RE ions, which therefore enhance the current properties of the material, and/or provide additional, such as luminescent emission in the visible spectrum. For example, RE-earth oxides, such as ARE2O4 (A = Ca, Sr, Ba, and RE = trivalent rare-earth ions, have great perspectives for producing highly efficient luminescent materials. So far, SrGd2O4 has been a poorly investigated material, even though it has huge potential for many different applications since it possesses high thermal stability, good chemical durability and it is environmentally friendly. The morphology and structure of the obtained particles are mostly influenced by the synthesis methods used for preparing the material. In this work, we will present structural and optical characterization of new material composed of SrGd2O4 doped with Yb3+ and Ho3+, but also, co-doped with Bi3+ ions, prepared via combustion method with glycine as a fuel and citric acid as a chelator. Samples of SrGd2O4 were doped with different Yb3+ (2, 4, 6 at%) ions and constant Ho3+ (1 at%) and Bi3+ (2 at%) concentrations. All samples were heated in the furnace for 1.5 hours at 500 °C and then thermally treated for 2.5 hours at 1000 °C. The pure orthorhombic lattice of SrGd2O4, space group Pnma, was revealed by X-ray diffraction (XRD) (JCPDS Card No.:01-072-6387). Transmission electron microscopy (TEM) discovered agglomerated clusters of spherical particles measuring around 150 nm in size. The inclusion of Bi3+ ions into the structure influenced the morphology since the formation of larger grains was observed, with sizes reaching up to ~1.7 μm, showing fine packing of pyramidal-shaped nanoparticles. The uniform distribution of constitutive elements in the samples was confirmed by energy dispersive spectroscopy (EDS). (activator). A substantial decrease in the energy band gap value was detected using diffuse reflectance spectroscopy (DRS UV-Vis) for this sample. Luminescent properties were evaluated from photoluminescent emission spectra and intensity dependence on excitation power after excitation at 976 nm. Dominant green (550 nm), red (671 nm), and infrared (758 nm) 5F4, 5S2 → 5I8, 5F5 → 5I8, 5F4, 5S2 → 5I7 transition emissions, respectively, are detected in all samples. The sample co-doped with Bi3+ showed the most intense photoluminescent emission.

AB  - As the Sun is the most abundant energy source available, solar cells can become the primary source of renewable energy. Today, one of the most promising candidates to achieve this goal is perovskite solar cells (PSC) since they are solution-processable with PCE (>25%) that surpass conventional Si photovoltaics. However, the commercial potential of PSCs is still mainly limited by the low stability of perovskite active/absorbing layer to the environmental stimuli. This is also an issue in the case of formamidinium lead iodide perovskite - CH(NH2)2PbI 3 (FAPbI3 or FAPI) which possesses several advantages to be an active layer of efficient PSC, in comparison to the counterpart methylammonium lead iodide- CH3NH3PbI3 (MAPI). It has been shown that the humidity and oxygen from the atmosphere, heat, UV light and ion migration may have detrimental influences leading to the degradation of quality of material, and corollary performance and stability of the device. The reason for this vulnerability of perovskites is the complexity of the material itself, which is a multielement and multi-component hybrid material. To address the stability of perovskite thin films and the consequent performance of PSCs, various materials such as organic acids, metallic and organic halides, amines, organosulfur compounds, graphene, polymers, etc., have been proposed as additives or surface passivation agents. In this work, we opt for poly(ionic) (PILs) liquids additives, which are polyelectrolyte salts comprising cations and anions, with the cationic or anionic centers constrained to the repeating units in the polymer chain. PILs offer several advantages (even in comparison to their monomer counterparts), including high ionic conductivity, low vapor pressure, high hydrophobicity, excellent thermal and electrochemical stability, and a tunable chemical structure. Based on these qualities, PILs have found applications in various thin film electronic devices such as solar cells, light-emitting diodes, capacitors, etc. Aforementioned aspects make them also suitable candidates for controlling the growth of perovskite crystals, passivating grain boundaries and surface defects, improving interfacial energetics, doping the perovskite and hole transport material, and overall enhancing the stability and efficiency of PSCs. Furthermore, PILs based on TFSI pendant anion have shown potential for preparing compact grains of perovskites in thin films with less pronounced grain boundaries, significantly reducing the J-V hysteresis index in PSCs [1]. Also, the use of TFSI-based PILs has demonstrated efficient passivation of defects at the surface of perovskite thin films, which greatly reduces interface recombination and consequently improves device efficiency and stability for different perovskite compositions and architectures [2]. Hence within this work, two poly(ionic) liquids based on polymerized anion bis(trifluoromethane)sulfonamide (TFSI) (with pendant cations Li+ and imidazolium, namely [PLiMTFSI] Li and [PLiMTFSI] [DCMim]) are used as additives along with the counterpart salt LiTFSI. As could be seen in Fig 1. where XPS data are presented, after addition of [PLiMTFSI] [DCMim] the greatest shift towards lower binding energy was observed which is subscribed to the strongest p-doping/interaction of/with perovskite thin film found in this case. Furthermore, from UV-Vis absorption and Photoluminescence spectra of pristine perovskite thin film and with additives presented in Fig. 2 can be inferred that the highest intensity was measured in both type of spectra in the case of perovskite film with additive [PLiMTFSI] [DCMim]. Here is expected that PIL most effectively passivates defects at the surface and grain boundaries of perovskite polycrystalline thin film, which is reflected in better quality of the thin film and corollary higher absorption. Indeed, in Fig. 3 can be observed that after addition of PIL additives (in contrast to LiTFSI) [PLiMTFSI] Li and especially [PLiMTFSI] [DCMim] into the perovskite thin film, crystallites of perovskite grow bigger and the thin film becomes more homogeneous and uniform.

However, the commercial potential of PSCs is still mainly limited by the low stability of perovskite active/absorbing layer to the environmental stimuli. This is also an issue in the case of formamidinium lead iodide perovskite - CH(NH2)2PbI 3 (FAPbI3 or FAPI) which possesses several advantages to be an active layer of efficient PSC, in comparison to the counterpart methylammonium lead iodide- CH3NH3PbI3 (MAPI). It has been shown that the humidity and oxygen from the atmosphere, heat, UV light and ion migration may have detrimental influences leading to the degradation of quality of material, and corollary performance and stability of the device. The reason for this vulnerability of perovskites is the complexity of the material itself, which is a multielement and multi-component hybrid material. To address the stability of perovskite thin films and the consequent performance of PSCs, various materials such as organic acids, metallic and organic halides, amines, organosulfur compounds, graphene, polymers, etc., have been proposed as additives or surface passivation agents. In this work, we opt for poly(ionic) (PILs) liquids additives, which are polyelectrolyte salts comprising cations and anions, with the cationic or anionic centers constrained to the repeating units in the polymer chain. PILs offer several advantages (even in comparison to their monomer counterparts), including high ionic conductivity, low vapor pressure, high hydrophobicity, excellent thermal and electrochemical stability, and a tunable chemical structure. Based on these qualities, PILs have found applications in various thin film electronic devices such as solar cells, light-emitting diodes, capacitors, etc. Aforementioned aspects make them also suitable candidates for controlling the growth of perovskite crystals, passivating grain boundaries and surface defects, improving interfacial energetics, doping the perovskite and hole transport material, and overall enhancing the stability and efficiency of PSCs. Furthermore, PILs based on TFSI pendant anion have shown potential for preparing compact grains of perovskites in thin films with less pronounced grain boundaries, significantly reducing the J-V hysteresis index in PSCs [1]. Also, the use of TFSI-based PILs has demonstrated efficient passivation of defects at the surface of perovskite thin films, which greatly reduces interface recombination and consequently improves device efficiency and stability for different perovskite compositions and architectures [2]. Hence within this work, two poly(ionic) liquids based on polymerized anion bis(trifluoromethane)sulfonamide (TFSI) (with pendant cations Li+ and imidazolium, namely [PLiMTFSI] Li and [PLiMTFSI] [DCMim]) are used as additives along with the counterpart salt LiTFSI. As could be seen in Fig 1. where XPS data are presented, after addition of [PLiMTFSI] [DCMim] the greatest shift towards lower binding energy was observed which is subscribed to the strongest p-doping/interaction of/with perovskite thin film found in this case. Furthermore, from UV-Vis absorption and Photoluminescence spectra of pristine perovskite thin film and with additives presented in Fig. 2 can be inferred that the highest intensity was measured in both type of spectra in the case of perovskite film with additive [PLiMTFSI] [DCMim]. Here is expected that PIL most effectively passivates defects at the surface and grain boundaries of perovskite polycrystalline thin film, which is reflected in better quality of the thin film and corollary higher absorption. Indeed, in Fig. 3 can be observed that after addition of PIL additives (in contrast to LiTFSI) [PLiMTFSI] Li and especially [PLiMTFSI] [DCMim] into the perovskite thin film, crystallites of perovskite grow bigger and the thin film becomes more homogeneous and uniform.",

AB  - Cancer represents one of the leading problems of today, with clinical detection oftentimes being difficult, currently based on imaging techniques, such as X-ray, computed tomography (CT) and magnetic resonance imaging (MRI). However, mortality rate is often reduced by early detection, therefore much focus has been directed towards developing methods for early detection of the disease.
Recent research in the field of nanotechnology is focused on the use of nanoparticles, particularly Lanthanide-doped up-conversion nanoparticles (UCNPs), for the detection of cancer cells using near infrared (NIR) fluorescence microscopy. The reason for this is that in long-term tracking tests, nearinfrared
(NIR) light, has lower phototoxicity and higher tissue penetration depth in living systems as compared with UV/VIS light. In this research, NaGd0.8Yb0.17Er0.03F4 UCNPs were prepared by solvothermal synthesis in the presence of chitosan, a ligand which enables UCNPs biocompatibility and the specific antibody conjugation. Morphological and structural characterization of synthetized UCNPs were performed based on X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and
photoluminescence spectroscopy (PL). Results confirmed the presence of the cubic phase with a minor portion of hexagonal phase in nanoparticles. Synthesized nanoparticles were conjugated further with anti-human CD44 antibodies, labeled with fluorescein isothiocyanate (FITC), which signal is used for confirmation of nanoparticles positioning in cells. Such obtained conjugates were successfully used for selective in vitro biolabeling of oral squamous cell carcinoma cells.

AB  - Y0.8−xGdxF3:Yb/Er mesocrystals with a biocompatible surface and diverse morphological characteristics were successfully synthesized using chitosan-assisted solvothermal processing. Their structural properties, studied using X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning and transmission electron microscopy and energy dispersive X-ray analysis, were further correlated with the up-conversion emission (λexc = 976 nm) recorded in function of temperature. Based on the change in the visible green emissions originating from the thermally coupled 2H11/2 and 4S3/2 levels of Er3+, the corresponding LIR was acquired in the physiologically relevant range of temperatures (25–50 °C). The detected absolute sensitivity of about 0.0042 °C−1, along with the low cytotoxicity toward both normal human lung fibroblasts (MRC-5) and cancerous lung epithelial (A549) cells, indicate a potential for use in temperature sensing in biomedicine. Additionally, their enhanced internalization in cells, without suppression of cell viability, enabled in vitro labeling of cancer and healthy cells upon 976 nm laser irradiation.

AB  - Hydroxyapatite attracts great attention as hard tissues implant material for bones and teeth. Its application in reconstructive medicine depends on its biocompatibility, which is in a function of composition and surface properties. The insertion of a protein element in the composition of implants can improve the cell adhesion and the osseointegration. Having this in mind, the proposal of this work was to develop L-alanine-grafted hydroxyapatite nanoparticles and to study their biocompatibility. Two L-alanine sources and three grafting methods were used for hydroxyapatite surface functionalization. The efficiency of grafting was determined based on X-ray powder diffraction, Fourier-transform infrared spectroscopy, thermal analyses, and field-emission scanning electron microscopy. The results indicated the formation of hydroxyapatite with 8–25 wt% of organic content, depending on the grafting method. Protein adsorption, cell adhesion, and viability studies were carried out to evaluate biological properties of grafted materials. The viability of MG-63 human osteoblastic cells following 24 h incubation with the alanine-grafted hydroxyapatite samples is well preserved, being in all cases above the viability of cells incubated with hydroxyapatite. The alanine-grafted hydroxyapatite prepared in situ and by simple mixture showed higher protein adsorption and cell adhesion, respectively, indicating their potential toward use in regenerative medicine.

AB  - Novel hybrid core-shell structures, in which up-converting (UC) NaYF4:Yb,Tm core converts near-infrared (NIR) to visible (Vis) light via multiphoton up-conversion processes, while anatase TiO2-acetylacetonate (TiO2-Acac) shell ensures absorption of the Vis light through direct injection of excited electrons from the highest-occupied-molecular-orbital (HOMO) of Acac into the TiO2 conduction band (CB), were successfully synthesized by a two-step wet chemical route. Synthesized NaYF4:Yb,Tm@TiO2-Acac powders were characterized by X-ray powder diffraction, thermogravimetric analysis, scanning and transmission electron microscopy, diffuse-reflectance spectroscopy, Fourier transform infrared spectroscopy, and photoluminescence emission measurement. Tetracycline, as a model drug, was used to investigate the photocatalytic efficiencies of the core-shell structures under irradiation of reduced power Vis and NIR spectra. It was shown that the removal of tetracycline is accompanied by the formation of intermediates, which formed immediately after bringing the drug into contact with the novel hybrid core-shell structures. As a result, ~80% of tetracycline is removed from the solution after 6 h.

AB  - Catalytic materials are the greatest challenge for the commercial application of water electrolysis (WEs) and fuel cells (FCs) as clean energy technologies. There is a need to find an alternative to expensive and unavailable platinum group metal (PGM) catalysts. This study aimed to reduce the cost of PGM materials by replacing Ru with RuO2 and lowering the amount of RuO2 by adding abundant and multifunctional ZnO. A ZnO@RuO2 composite in a 10:1 molar ratio was synthesized by microwave processing of a precipitate as a green, low-cost, and fast method, and then annealed at 300°C and 600°C to improve the catalytic properties. The physicochemical properties of the ZnO@RuO2 composites were investigated by X-ray powder diffraction (XRD), Raman and Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), UV-Vis diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) spectroscopy. The electrochemical activity of the samples was investigated by linear sweep voltammetry in acidic and alkaline electrolytes. We observed good bifunctional catalytic activity of the ZnO@RuO2 composites toward HER and OER in both electrolytes. The improved bifunctional catalytic activity of the ZnO@RuO2 composite by annealing was discussed and attributed to the reduced number of bulk oxygen vacancies and the increased number of established heterojunctions.

AB  - In this investigation, samples of strontium-gadolinium-oxide (SrGd2O4) doped with different Yb3+ (2, 4 and 6 at%) and constant Ho3+ (1 at%) contents and co-doped with Bi3+ (2 at%) were prepared using the glycine-assisted sol–gel method. The pure orthorhombic SrGd2O4 phase, space group Pnma, was revealed using X-ray diffraction in all samples. Transmission electron microscopy discovered agglomerated clusters of spherical particles measuring approximately 150 nm in size. The inclusion of Bi3+ ions into the structure influenced the morphology since the formation of larger grains was observed, with sizes reaching up to ∼1.7 μm. The uniform distribution of all constitutive elements was confirmed by energy-dispersive X-ray spectroscopy. In all samples, up-conversion emission spectra revealed two dominant green (540 and 550 nm), red (671 nm), and infrared (758 nm) emission lines, due to the 5F4,5S2→5I8, 5F5→5I8, and 5F4,5S2 → 5I7 transitions, respectively. The sample co-doped with Bi3+ showed the most intense photoluminescent emissions, shorter luminescence decay, and the highest quantum yield. Additionally, a significant decrease in the energy band gap value was detected using diffuse reflectance spectroscopy for this sample. Methylene blue was used as a test pollutant to investigate its photocatalytic efficiency under simulated sunlight irradiation. The results show that Bi3+ co-doping deteriorates the photocatalytic efficiency of the SrGd2O4:Yb3+/Ho3+ phase by reducing hydroxyl radical formation.

AB  - There is a great technological interest in synthesis of lanthanide doped upconverting nanoparticles (UCNPs) with controlled crystal phase, morphology and intense luminescence properties suitable for biomedical use. A conventional approach for synthesis of such particles comprises decomposition of organometallic compounds in an oxygen-free environment, followed either with a ligand exchange, or biocompatible layer coating. Biocompatible NaY0.65Gd0.15F4:Yb,Er nanoparticles used in this study were synthesized through chitosan assisted one-pot hydrothermal synthesis and were characterized by X-ray powder diffraction (XRPD), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM/EDS) and photoluminescence measurement (PL). Due to the presence of the amino groups at their surface, excellent biocompatibility and notably low cytotoxicity against MRC-5 cells (line of normal human fibroblasts) and A549 cells (human lung cancer cells) were detected using MTT assay. Furthermore, upon 980 nm laser irradiation, particles were successfully used in vitro for labeling of both, MRC-5 and A549 cells.

AB  - The aim of this research was to investigate for the first-time photocatalytic degradation of methylene blue over SrGd2O4 powders co-doped with constant Er3+ (0.5 at.%) and different Yb3+ (1, 2.5 and 5 at.%) concentrations. Samples were successfully prepared via sol-gel assisted combustion method. They exhibit photoluminescence properties which are manifested as red emission at 661 nm (4F9/2 → 4I15/2) and two green emissions at 551 and 523 nm (4S3/2 → 4I15/2 and 2H11/2 → 4I15/2). X-ray Powder Diffraction pattern proved that all samples crystallize as a pure orthorhombic phase. Scanning electron microscopy was used for morphology characterization and it revealed the existence of porous agglomerated round-shaped particles. Energy dispersive X-ray spectroscopy showed the presence of dopant ions and even distribution of all constituting elements. To calculate the energy band gap, UV-VIS diffuse reflectance spectroscopy was performed and a value of 4.3 eV was obtained, as well as the four additional values from the bands at lower energies. Photocatalytic degradation of methylene blue was monitored using UV-VIS absorption spectroscopy. Obtained results were promising since after 4 h of exposure to the simulating Sun irradiation, more than 50% of the starting dye concentration was mineralized.

AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules. Considering that the photocatalytic activity of the cotton-based TiO2 and TiO2/Ag samples was practically imperceptible, it can be assumed that the synthesized Ag NPs act predominantly as electron traps in the double-loaded synthesized system.

AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules.

AB  - In this investigation, samples of strontium-gadolinium-oxide (SrGd2O4) doped with different Yb3+ (2, 4 and 6 at%) and constant Ho3+ (1 at%) contents and co-doped with Bi3+ (2 at%) were prepared using the glycine-assisted sol–gel method. The pure orthorhombic SrGd2O4 phase, space group Pnma, was revealed using X-ray diffraction in all samples. Transmission electron microscopy discovered agglomerated clusters of spherical particles measuring approximately 150 nm in size. The inclusion of Bi3+ ions into the structure influenced the morphology since the formation of larger grains was observed, with sizes reaching up to ∼1.7 μm. The uniform distribution of all constitutive elements was confirmed by energy-dispersive X-ray spectroscopy. In all samples, up-conversion emission spectra revealed two dominant green (540 and 550 nm), red (671 nm), and infrared (758 nm) emission lines, due to the 5F4,5S2→5I8, 5F5→5I8, and 5F4,5S2 → 5I7 transitions, respectively. The sample co-doped with Bi3+ showed the most intense photoluminescent emissions, shorter luminescence decay, and the highest quantum yield. Additionally, a significant decrease in the energy band gap value was detected using diffuse reflectance spectroscopy for this sample. Methylene blue was used as a test pollutant to investigate its photocatalytic efficiency under simulated sunlight irradiation. The results show that Bi3+ co-doping deteriorates the photocatalytic efficiency of the SrGd2O4:Yb3+/Ho3+ phase by reducing hydroxyl radical formation.

AB  - Novel hybrid core shell structure with extensive absorption was synthesized by a two-step wet chemical route. Up-converting β-NaYF4:Yb,Tm core was obtained through EDTA assisted hydrothermal process, while the shell of anatase TiO2-Acetylacetonate charge transfer complex (TiO2-Acac) was formed over these via sol-gel method. Tetracycline was used to investigate photocatalytic efficiency of obtained structure under irradiation of reduced power Vis and NIR spectra. Owing to the fact that 1D2→3F4 and 1G4→3H6 emission of Tm3+ matches well with the absorption edge of TiO2-Acac, radiation-reabsorption and FRET processes improve the overall generation of reactive oxygen species and degradation of tetracycline. Beside it, formation of tetracycline intermediates immediately after the addition of this novel hybrid core-shell structures, making them a promising material for water purification through the synergy of catalytic and photocatalytic processes.

AB  - Nanopowders of up-conversion SrGd2O4 orthorhombic (Pnma) phase co-doped with different Yb3+ (1, 2.5 and 5 at%) and constant Er3+ (0.5 at%) ions were successfully prepared via sol-gel assisted combustion. Rietveld refinement indicated unit cell lattice parameters increase with Yb3+ and Er3+ ions doping. Scanning transmission electron microscopy with corresponding energy-dispersive X-ray spectroscopy revealed that obtained powders are composed of agglomerated nanoparticles that have a uniform distribution of all constituting elements. Photoluminescence measurements implied intensification of the up-conversion (UC) emission in the visible part of spectrum with the increase of Yb3+ content, which is followed by a significant change in the green to red ratio. Two-photon UC processes are established as a result of Er3+ f-f electronic transitions: green emission at 523 and 551 nm (2H11/2, 4S3/2 → 4I15/2) as well as a red emission at 661 nm (4F9/2 → 4I15/2). The highest value of absolute quantum yield of 0.055% is determined for SrGd2O4 nanoparticles doped with 0.5 at% of Er3+ and co-doped with 5 at% of Yb3+ (λexc = 976 nm, power density 200 W/cm2).

AB  - In this work we present new up-conversion materials, consisted of SrGd2O4 doped with different concentration of Yb3+ (2, 4, 6 at%) ions and constant concentration of Tm3+ (1 at%), prepared by the combustion method. X-ray powder diffraction (XRPD) showed that assynthesized nanoparticles have orthorhombic structure (Pnma), assigned to the JCPDS Card No:01-072-6387. Scanning electron microscopy (SEM) revealed that obtained nanostructure is composed of porous agglomerated nanoparticles, while energy dispersive spectroscopy (EDS) confirmed presence and uniform distribution of all constituting elements accross the sample. Luminescent properties were evaluated and discovered two blue emission bands at 450 nm and 474 nm, and one red emission band at 650 nm. The sample co-doped with 4 at% Tm3+ showed the most intense photoluminescent emission, and because of that was used in the photocatalytic exiperiment. UV-VIS Diffuse Reflectance Spectroscopy was performed in order to examine materials bandgap, and value of 4.3 eV was obtained as well as the additional values from the bands at lower energies, which indicate potentially good photocatalytic properties. X-ray photoelectron spectroscopy (XPS) revealed presence of OHgroups on the surface which also have positive impact on the photocatalytic performances of the material. UV-VIS Absorption Spectroscopy was used to measure changes of the methylene blue concentration during the photocatalytic degradation process. After 4 h of exposure to the simulating Sun irradiation, the results indicate successful dye decomposition rate. Reaction parameters (MB concentration and catalyst mass) were altered in order to achieve the best photocatalytic performances of this newly synthesized materials.

The sample co-doped with 4 at% Tm3+ showed the most intense photoluminescent emission, and because of that was used in the photocatalytic exiperiment. UV-VIS Diffuse Reflectance Spectroscopy was performed in order to examine materials bandgap, and value of 4.3 eV was obtained as well as the additional values from the bands at lower energies, which indicate potentially good photocatalytic properties. X-ray photoelectron spectroscopy (XPS) revealed presence of OHgroups on the surface which also have positive impact on the photocatalytic performances of the material. UV-VIS Absorption Spectroscopy was used to measure changes of the methylene blue concentration during the photocatalytic degradation process. After 4 h of exposure to the simulating Sun irradiation, the results indicate successful dye decomposition rate. Reaction parameters (MB concentration and catalyst mass) were altered in order to achieve the best photocatalytic performances of this newly synthesized materials.",

AB  - There are numerous researches on biomaterials, with the association of some natural and synthetic polymers and ceramic materials, for the development of hydrogels and bioinks, in an attempt to develop a biomaterial that is resistant, biocompatible and bioactive, which forms a bond with the host tissues and promotes tissue regeneration. The purpose of this work is to produce a bioink based on a hydrogel of chemically oxidized cellulose and bioglass (58S) for application in regenerative medicine. In this study, the chemically oxidized cellulose gel was obtained from a natural source of sugar cane bagasse, the material was washed, bleached, chemically treated with the TEMPO reagent and sonicated to obtain a viscous gel. Tertiary bioglass (58S) obtained by the sol-gel method was used because it showed better viability and cell proliferation. Chemically oxidized cellulose and bioglass (58S) were combined to form the composite. The results obtained were promising for characterizing the composite as a bioink. In this way, the rheological tests characterized the composite as a hydrogel. Subsequently, to form the bioink, bone cells (MG-63) were inserted inside the hydrogel. The results of the cell tests showed that after ten days the cells were still viable, as well as DAPI showing that the cells were inserted inside the material, characterizing it as a bioink and the Alizarin Red test showing the ability to form a mineralized matrix.

AB  - Nanopowders of up-conversion SrGd2O4 orthorhombic (Pnma) phase co-doped with different Yb3+ (1, 2.5 and 5 at%) and constant Er3+ (0.5 at%) ions were successfully prepared via sol-gel assisted combustion. Rietveld refinement indicated unit cell lattice parameters increase with Yb3+ and Er3+ ions doping. Scanning transmission electron microscopy with corresponding energy-dispersive X-ray spectroscopy revealed that obtained powders are composed of agglomerated nanoparticles that have a uniform distribution of all constituting elements. Photoluminescence measurements implied intensification of the up-conversion (UC) emission in the visible part of spectrum with the increase of Yb3+ content, which is followed by a significant change in the green to red ratio. Two-photon UC processes are established as a result of Er3+ f-f electronic transitions: green emission at 523 and 551 nm (2H11/2, 4S3/2 → 4I15/2) as well as a red emission at 661 nm (4F9/2 → 4I15/2). The highest value of absolute quantum yield of 0.055% is determined for SrGd2O4 nanoparticles doped with 0.5 at% of Er3+ and co-doped with 5 at% of Yb3+ (λexc = 976 nm, power density 200 W/cm2).

AB  - Over the last few years there has been a great interest in developing the efficient methodologies for the preparation of rare earth doped up-converting nanoparticles (UCNPs), which exhibit emission in visible part of spectra when excited by the near infrared (NIR) radiation. Due to this unique optical property, as well as the high chemical stability they could be used either as security or fluorescent biological labels. Depending on the host crystal structure and choice of the dopant, these could exhibit different luminescence response. In this work we represent the effect which hydro/solvo thermal treatment and simple co-precipitation have on structural, morphological and optical properties of NaYF4:Yb,Er UCNPs. We showed that pure cubic phase crystallizes in monodisperse spherical nanoparticles obtained through hydro/solvothermal synthesis, while co-precipitation and annealing at 500°C for 5 hours leads to the obtaining of agglomerated microparticles with hexagonal phase. Due to the difference in size and morphology of the samples, the different up-conversion mechanisms are established upon the excitation by the infrared light (λ = 978 nm), intensifying green emission (2H11/2,4S3/2 →4I15/2 ) in sample obtained through hydro/solvo thermal synthesis.
