AB  - In this paper, we present the results of an experimental study about a novel fiber optical vibrometer, aimed to be used as a totally implantable fiber-optic microphone for hearing aids. The sensor head, implanted inside the human cadaver middle ear, detects the amplitude of the incus vibrations, which are produced by an external acoustical source. The probe beam of coherent vertical cavity surface emitting laser (VCSEL) radiation is directed to the incus and the phase-modulated reflected beam is captured and demodulated. The problem of interferometric fading was solved using two quasi-quadrature signals, passively produced by the 3 × 3 single-mode fiber-optic coupler, processed by a special embedded algorithm. The implanted optoelectronic module works with very low-power consumption, performs real-time signal processing and outputs an analogue signal proportional to the incus vibration. The amplitude of the incus vibrations at different sound pressure levels (SPL) from 40 to 90 dB and at frequencies from 100 Hz to 10 kHz were measured by the implanted system. The system was evaluated on five cadaver skulls. The measured amplitudes were in the range of 1 pm to 5 nm, depending on the subjected skull and the applied sound pressure.

AB  - In this work we present new up-conversion materials, consisted of SrGd2O4 matrix co-doped with different Yb3+ (1, 2.5 and 5 at%) and constant Er3+ (0.5 at%) concentrations, prepared by gycine-assisted combustion method. X-ray powder diffraction (XRPD) showed that assynthesized nanoparticles have orthorhombic structure (Pnma), assigned to the JCPDS Card No:01-072-6387. Rietveld refinement indicated a decrease in the size of the unit cell, lattice parameters, and cell volume, due to successful doping of Yb3+ and Er3+ ions into the matrix. Transmission electron microscopy (TEM) revealed that obtained nanostructure is composed of agglomerated nanoparticles, while energy dispersive spectroscopy (EDS) confirmed uniform distribution of all constituting elements in them. Up-conversion (UC) luminescence spectra measured in function of laser pumping power indicated that two-photon UC process is established in nanoparticles as a result of the trivalent erbium f-f electronic transitions: there are two green emission bands at 523 and 551 nm (2H11/2, 4S3/2 → 4I15/2) and a red emission band at 661 nm (4F9/2 → 4I15/2). The rise of Yb3+ concentration from 1 to 5 at% provokes a considerable change of the green to red ratio which indicates the possibility to optimize the color output.

AB  - Synthesis of monosized and spherical Up-Converting NanoParticles (UCNPs) with biocompatible surface are of a great interest because of their potential application in biomedicine as biomarkers or drug delivery systems. Among different synthesis routes reported in the literature, a hydro/solvo thermal method is consider to be most potential one for scaling-up due fact that is simple and economically cost-effective. In this work the synthesis of NaY0.65Gd0.15F4:Yb,Er UCNPs were performed through chitosan assistant solvothermal synthesis at 200oC. Variation of precursors concentration, type of solvent and synthesis time were performed in order to explore their influence on the structural, morphological and optical properties of the UCNPs. The XRD analysis showed that with a smaller surplus of fluoride ions the formation of Y0.65Gd0.15F4:Yb,Er orthorhombic phase occurs, while the increase of fluoride content or reaction time leads to NaY0.65Gd0.15F4:Yb,Er cubic phase formation. Along with it, the changes of UCNPs morphology from spindle to spherical shape is detected. All samples emitintense green emission due to the (2H11/2, 4S3/2) → 4I15/2electronic transitions, after been excited with infrared light (λ=978 nm).

AB  - The aim of this research was to improve photo(electro)catalytic properties of BaTi1-xSnx (BTS, x = 0, 0.05, 0.10) powders. For that purpose we employed ZnO to prepare ZnO@BTS composite. In situ microwave processing of a ZnO precipitate on previously synthesized BTS particles was used to produce ZnO@BTS composites. The phase composition and crystal structure of BTS, ZnO and ZnO@BTS were examined by X-ray powder diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The powders particles morphology was investigated by field emission scanning electron microscopy (FESEM). The optical properties were studied using UV-Vis diffuse reflectance (DRS) and photoluminescence spectroscopy (PL). Linear voltammetry was used to examine the photoelectrochemical properties of the materials. Photocatalytic properties were tested based on the decolorization of methylene blue (MB) dye in the presence of powder particles, under the influence of simulated sunlight radiation. BTS powders have good electron transfer properties, which has been shown in their function as electrocatalysts, where they have shown better properties than ZnO and ZnO@BTS composites. In contrast, they showed poor photocatalytic efficacy. The precipitation of ZnO particles on BTS, by the method of microwave processing,
significantly improves the photocatalytic efficiency of the formed composites, concerning the starting BTS powders. Among the composites, ZnO@BT composite proved to be the most effective photocatalyst.

AB  - Perovskite solar cells reached high efficiency in a short period. When perovskite was applied for the first time as photovoltaics, power conversion efficiency (PCE) was less than 3 %. Up to now, PCE is over 29 %. In perovskite solar cells, the perovskite layer is an active layer that absorbs the visible part of the spectrum. To reduce the recombination of charge carriers, the construction of solar cells requires the existence of layers for holes and electrons. TiO2 is usually used as an inorganic electron transport layer because its conduction band (CB) lies under the CB of perovskite, so electrons could diffuse from CB of perovskite to CB of TiO2. For these experiments, TiO2 nanotubular structure was used due to its advantages compared to nanoparticular TiO2. TiO2 nanotubes provide a one-dimensional transmission channel for the charge carriers which will reduce the recombination of the carriers and provide a fast carrier transport. The TiO2 nanotubes were synthesized by anodization of Ti foil after which they were annealed at 450 °C for 1 h. Their inner diameter was ~ 103 ± 17 nm while the length was ~ 350 nm. Methylammonium lead bromide perovskite (MAPbBr3) was deposited on TiO2 nanotubes from the solution in dimethylformamide (DMF) by application of supercritical carbon dioxide at 35 °C and different pressures (100, 200, and 300 bar). It has been observed that supercritical CO2 improves the filling of nanotubes by the perovskite due to its stronger solubilizing power at higher pressures. A perovskite photodiode with an improved contact surface between TiO2 and perovskite was made, which is the basis for future solar cell construction. I-V characteristics show that the highest value of photocurrent under visible light reached 400 μA for the sample which was obtained at 35 ° C and 300 bar for 1 h. The absorption edge of prepared TiO2 nanotubes/MAPbBr3, determined by diffuse reflectance spectroscopy, was extended to the visible range. FESEM and XRD analyses also were done.

AB  - This paper presents a class of integer codes suitable for use in optical networks with low error rates. The presented codes are constructed with the help of a computer and have two important features: first, they can correct single errors affecting one or two b-bit bytes, and second, they use processor-friendly operations to encode/decode data bits. The effectiveness of the presented codes is demonstrated on theoretical models of four-core and six-core processors. The obtained results show that the decoder throughput reaches 14.70Gbps, which is above the operating speed of 10G networks. Finally, the paper compares the proposed codes with BCH codes of similar properties. The comparison is made in terms of redundancy and the number of decoding operations.

abstract = "This paper presents a class of integer codes suitable for use in optical networks with low error rates. The presented codes are constructed with the help of a computer and have two important features: first, they can correct single errors affecting one or two b-bit bytes, and second, they use processor-friendly operations to encode/decode data bits. The effectiveness of the presented codes is demonstrated on theoretical models of four-core and six-core processors. The obtained results show that the decoder throughput reaches 14.70Gbps, which is above the operating speed of 10G networks. Finally, the paper compares the proposed codes with BCH codes of similar properties. The comparison is made in terms of redundancy and the number of decoding operations.",

AB  - Just in the immediate neighbourhood of the European Union (EU), the Republic of Serbia, one of the Western Balkan (WB) EU candidate countries, is lagging behind in the process of energy transition regardless of technological advances and policy instruments available. The EU created a momentum for energy transition acceleration with the European Green Deal, which has been forwarded to the WB through the Energy Community secretariat in the form of the Green Agenda; generally speaking, response in the form of National Energy and Climate Plans (NECPs) is expected in the short term. The Republic of Serbia’s Low Carbon Development Strategy with Action Plan (LCDSA) and the current Energy Strategy will be analysed, commented on, and improvements will be suggested for the acceleration of energy transition, based on the newest findings from the simulation-based optimization techniques using the sector coupling approach to achieve ambitious variable renewable energy shares. The motivation of this research is to provide decision makers in Serbia with the best available insights regarding sustainable energy system planning tools and possible shortcuts for delayed planning of activities. In addition, the purpose is to improve Serbia’s chance of benefitting from adoption of these strategies in the country’s faster transition towards EU membership. The research compares two scenarios to illustrate a possible policy shift from small hydro power plants to photovoltaics (PV). A further increase in PV and wind power plants has been simulated using the EnergyPLAN to achieve expected scenarios of 40% renewable energy share and some more ambitious ones—up to 80%, which is realistic only with the sector coupling approach.

AB  - In this paper, we present the results of an experimental study about a novel fiber optical vibrometer, aimed to be used as a totally implantable fiber-optic microphone for hearing aids. The sensor head, implanted inside the human cadaver middle ear, detects the amplitude of the incus vibrations, which are produced by an external acoustical source. The probe beam of coherent vertical cavity surface emitting laser (VCSEL) radiation is directed to the incus and the phase-modulated reflected beam is captured and demodulated. The problem of interferometric fading was solved using two quasi-quadrature signals, passively produced by the 3 × 3 single-mode fiber-optic coupler, processed by a special embedded algorithm. The implanted optoelectronic module works with very low-power consumption, performs real-time signal processing and outputs an analogue signal proportional to the incus vibration. The amplitude of the incus vibrations at different sound pressure levels (SPL) from 40 to 90 dB and at frequencies from 100 Hz to 10 kHz were measured by the implanted system. The system was evaluated on five cadaver skulls. The measured amplitudes were in the range of 1 pm to 5 nm, depending on the subjected skull and the applied sound pressure.

AB  - Monitoring the occurrence and rate of corrosion, the formation of thermal oxides on the surface of metal parts of the power plant, as well as the method of their elimination in a way that is technologically suitable, economically affordable and environmentally justified is shown in this technical solution. It has been established that the metal elements affected by corrosion were made from stainless steel AISI 304. Accordingly, the occurrence of corrosion and thermal oxides was monitored based on the material and the composition of the dust with which the metal parts are in contact. The emergence of thermal oxides on the surface of stainless steels is a consequence of the elevated temperature at the welding site.
The pH value of both solutions was measured: standard and saturated solution of dust from the plant. The composition of the dust samples was determined by FTIR. The other tests were defined based on the ions present in the solution.
The corrosion potential, the value of the polarization resistance, as well as the corrosion current density were determined. All tests of stainless steel in the standard solution and in the saturated solution of dust were performed for one hour within a span of 25 days.
Technological recommendations on how to eliminate corrosion and thermal oxides are provided.
The solution has been applied since January 2021 by ELNOS BL d.o.o.

AB  - The cytotoxicity of amorphous calcium phosphate (ACP) and chitosan lactate (ChOL) multifunctional and hybrid composite coatings on MRC-5 human lung fibroblast cell line was elucidated. ACP/TiO2 and ACP/TiO2/ /ChOL were deposited onto Ti by a novel in situ anodization/anaphoretic process at constant voltage. Cytotoxicity tests showed that there was no significant decrease in the survival of healthy MRC-5 cells exposed to composite samples without chitosan lactate, while there was an increase in the number of viable cells in the sample containing ChOL. These findings show that there was improved cell proliferation, differentiation and cell viability in the ChOL-containing sample, which makes ACP/TiO2/ChOL coating a good candidate for applications in medicine and stomatology.

AB  - This paper describes the importance of the interoperability in smart metering systems for modern distribution system operators. The lack of interoperability significantly increases the costs of smart metering system implementation for distribution system operators, especially the costs of purchasing new equipment. The replacement, cleanup and maintenance of electricity meters produced by different manufacturers, which are not interoperable, are also much more complex and expensive. Furthermore, without the interoperability, the system cannot be observable, i.e. the observability exists only for some particular segments of the system. This prevents many functionalities of distribution management system. In terms of interoperability, smart metering systems have gone through four different stages. A comparison of the system implementation costs for these four stages is presented for distribution system operator of Serbia.

Main technical challenge and a key factor in techno-economic analysis of the energy system of the future, based on variable renewable energy sources, is their variable production and its integration. In order to deal with this problem in long-term energy planning, different approaches have been tried, focusing on overcapacity, storage capacities and sectors coupling with heating and transport. In this research, different flexibility options, storage and demand response technologies are modelled on a national energy systems level. With the case study area modelled in EnergyPLAN model, the goal of the research is to show how each flexibility option influences the economically feasible generation capacities of renewable energy sources, storage technologies and demand response in order to reach a certain share of renewable energy in final energy consumed. To follow the numerous possible configurations of the system, flexibility index for each option and a flexibility vector for each scenario are introduced. Results show which flexibility options play key role in important steps of energy transition to 70%, 80%, 90% and 100% RES energy system.

Field emission scanning electron microscopy (FESEM) showed that microsized powder is obtained. X-ray powder diffraction (XRD) pattern is used for both phase identification and crystal structure Rietveld refinement. The structure is refined in the orthorhombic Pbnm space group. Mössbauer spectroscopy revealed traces of Fe3+ impurity. The bond valence mapping method is applied for the first time on Fe2SiO4 framework. It shows isolated, non-connected isosurfaces of constant E(Li), which further supports the assumptions of the conversion reactions. Electrochemical performances are investigated through galvanostatic cycling, cyclic voltammetry, and electrochemical impedance spectroscopy (EIS). Ex-situ XRD and Fourier transform infrared spectroscopy (FTIR) analyses are combined to monitor phase change after galvanostatic cycling and to reveal the working mechanism during electrochemical lithiation.

AB  - Nucleation of minerals in the presence of additives is critical for achieving control over the formation of solids in biomineralization processes or during syntheses of advanced hybrid materials. Herein, we investigated the early stages of Fe(III) (oxy)(hydr)oxide formation with/without polyglutamic acid (pGlu) at low driving force for phase separation (pH 2.0 to 3.0). We employed an advanced pH-constant titration assay, X-ray diffraction, thermal analysis with mass spectrometry, Fourier Transform infrared spectroscopy, and scanning electron microscopy. Three stages were observed: initial binding, stabilization of Fe(III) pre-nucleation clusters (PNCs), and phase separation, yielding Fe(III) (oxy)(hydr)oxide. The data suggest that organic–inorganic interactions occurred via binding of olation Fe(III) PNC species. Fourier Transform Infrared Spectroscopy (FTIR) analyses revealed a plausible interaction motif and a conformational adaptation of the polypeptide. The stabilization of the aqueous Fe(III) system against nucleation by pGlu contrasts with the previously reported influence of poly-aspartic acid (pAsp). While this is difficult to explain based on classical nucleation theory, alternative notions such as the so-called PNC pathway provide a possible rationale. Developing a nucleation theory that successfully explains and predicts distinct influences for chemically similar additives like pAsp and pGlu is the Holy Grail toward advancing the knowledge of nucleation, early growth, and structure formation.

AB  - Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 °C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray diffraction and FT-IR spectroscopy analysis confirmed the formation of nickel manganite with a cubic spinel structure, while N2 physisorption at 77 K enabled determination of the BET specific surface area as 25.3 m2/g and (BJH) mesopore volume as 21.5 m2/g. The material constant (B) of the nanocrystalline nickel manganite fibers applied by drop-casting on test interdigitated electrodes on alumina substrate, dried at room temperature, was determined as 4379 K in the 20–50 °C temperature range and a temperature sensitivity of −4.95%/K at room temperature (25 °C). The change of impedance with relative humidity was monitored at 25 and 50 °C for a relative humidity (RH) change of 40 to 90% in the 42 Hzπ1 MHz frequency range. At 100 Hz and 25 °C, the sensitivity of 327.36 ± 80.12 kΩ/%RH was determined, showing that nickel manganite obtained by electrospinning has potential as a multifunctional material for combined humidity and temperature sensing.

abstract = "Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 °C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray diffraction and FT-IR spectroscopy analysis confirmed the formation of nickel manganite with a cubic spinel structure, while N2 physisorption at 77 K enabled determination of the BET specific surface area as 25.3 m2/g and (BJH) mesopore volume as 21.5 m2/g. The material constant (B) of the nanocrystalline nickel manganite fibers applied by drop-casting on test interdigitated electrodes on alumina substrate, dried at room temperature, was determined as 4379 K in the 20–50 °C temperature range and a temperature sensitivity of −4.95%/K at room temperature (25 °C). The change of impedance with relative humidity was monitored at 25 and 50 °C for a relative humidity (RH) change of 40 to 90% in the 42 Hzπ1 MHz frequency range. At 100 Hz and 25 °C, the sensitivity of 327.36 ± 80.12 kΩ/%RH was determined, showing that nickel manganite obtained by electrospinning has potential as a multifunctional material for combined humidity and temperature sensing.",

AB  - Moving from fossil fuels toward renewable resources of energy has a worldwide consensus. Solar energy alone can satisfy all our energy requirements since the earth receives 725 ZJ of energy from the sun each year while total human energy consumption in 2019 was 0.584 ZJ. The 2010s are highlighted as a transitional decade when the photovoltaic conversion industry transformed from a subsidized to a profitable energy sector. While photovoltaic energy conversion is a clean process, technologies for producing photovoltaic materials and solar panels affect the environment. The utilization of photovoltaic materials with low impact on the environment during the entire life cycle will mark the beginning of the sustainable transition toward 100% clean renewable energy sources in a sustainable manner. Thus far, only perovskite compounds have the potential to satisfy these requirements because of their theoretical conversion efficiencies, ease of synthesis, production scalability, adaptability, and comparability to existing photovoltaic systems. In this article, the rise of the photovoltaic industry in the last decade is shown and requirements in further transition from renewable to clean sources of renewable energy are foreseen.

AB  - The aim of this work was to investigate corrosion resistivity, bioactivity, and antibacterial activity of novel nano-amorphous calcium phosphate (ACP) potentially multifunctional composite coatings with and without chitosan oligosaccharide lactate (ChOL), ACP + ChOL/TiO2 and ACP/TiO2 ACP + ChOL/TiO2, respectively, on the titanium substrate. The coatings were obtained by new single-step in situ anodization of the substrate to generate TiO2 and the anaphoretic electrodeposition process of ACP and ChOL. The obtained coatings were around 300 ± 15 μm thick and consisted of two phases, namely, TiO2 and hybrid composite phases. Both ACP/TiO2 and ACP + ChOL/TiO2 have improved corrosion stability, whereas the ACP + ChOL/TiO2 coating showed better corrosion stability. It was shown that at the very start of the deposition process, the formation of the ChOL/TiO2 layer takes place predominantly, which is followed by the inclusion of ChOL into ACP with simultaneous growth of TiO2. This deposition mechanism resulted in the formation of strongly bonded uniform stable coating with high corrosion resistance. In vitro bioactivity was investigated by immersion of the samples in simulated body fluid (SBF). There is in-bone-like apatite formation on both ACP/TiO2 and ACP + ChOL/TiO2 surfaces upon immersion into SBF, which was proven by X-ray diffraction and Fourier transform infrared spectroscopy. While ACP/TiO2 shows no antibacterial activity, ACP + ChOL/TiO2 samples exhibited three- to fourfold decreases in the number of Staphylococcus aureus and Pseudomonas aeruginosa, respectively, after 420 min. The probable mechanism is binding ChOL with the bacterial cell wall, inhibiting its growth, altering the permeability of the cell membrane, and leading to bacterial death.

AB  - Four silver-based coordination polymers, {[Ag(L1)2]NO3}∞ (1), {[Ag(L1)2]ClO4}∞ (2), {[Ag(L2)2]NO3·H2O}∞ (3) and {[Ag(L2)2]ClO4}∞ (4), were synthesized using the thiomorpholine-4-carbonitrile (L1) and piperazine-1,4-dicarbonitrile (L2) ligands. Compounds 1 and 2 are two-dimensional, while 3 and 4 are three-dimensional. L1 and L2 are 1,4-bis-monodentate ligands in all compounds, while Ag(I) ions are four-coordinated in a slightly distorted tetrahedral geometry. Topological analysis in standard representations suggests that underlying nets in 1 and 2 have an sql topology, while 3 and 4 exhibit a dia topology. Thermal analysis shows that 3 loses crystalline water at room temperature, while other compounds show good thermal stability. All compounds show good photocatalytic activity for photocatalytic degradation of the mordant blue 9 dye, with reaction rates in the range 0.029 to 0.061 min−1. The best result was obtained for compound 4, which can be correlated to its largest lattice volume.

AB  - The aim of this work was to investigate corrosion resistivity, bioactivity, and antibacterial activity of novel nano-amorphous calcium phosphate (ACP) potentially multifunctional composite coatings with and without chitosan oligosaccharide lactate (ChOL), ACP + ChOL/TiO2 and ACP/TiO2 ACP + ChOL/TiO2, respectively, on the titanium substrate. The coatings were obtained by new single-step in situ anodization of the substrate to generate TiO2 and the anaphoretic electrodeposition process of ACP and ChOL. The obtained coatings were around 300 ± 15 μm thick and consisted of two phases, namely, TiO2 and hybrid composite phases. Both ACP/TiO2 and ACP + ChOL/TiO2 have improved corrosion stability, whereas the ACP + ChOL/TiO2 coating showed better corrosion stability. It was shown that at the very start of the deposition process, the formation of the ChOL/TiO2 layer takes place predominantly, which is followed by the inclusion of ChOL into ACP with simultaneous growth of TiO2. This deposition mechanism resulted in the formation of strongly bonded uniform stable coating with high corrosion resistance. In vitro bioactivity was investigated by immersion of the samples in simulated body fluid (SBF). There is in-bone-like apatite formation on both ACP/TiO2 and ACP + ChOL/TiO2 surfaces upon immersion into SBF, which was proven by X-ray diffraction and Fourier transform infrared spectroscopy. While ACP/TiO2 shows no antibacterial activity, ACP + ChOL/TiO2 samples exhibited three- to fourfold decreases in the number of Staphylococcus aureus and Pseudomonas aeruginosa, respectively, after 420 min. The probable mechanism is binding ChOL with the bacterial cell wall, inhibiting its growth, altering the permeability of the cell membrane, and leading to bacterial death.

AB  - One of the greatest environmental goals for the aluminum alloys industry is generating higher quality products by introducing cleaner input materials while maintaining low production costs. A typical dilemma for the master alloy producers is the cleanness level of the master alloy since insoluble inclusions could serve as inoculants during the solidification process. In this work, commercial Ti5B1 master alloy is used for grain refinement of Al7Si4Cu aluminum alloy and compared with the cleaned master alloy that contained a lower amount of residual refractory oxides and salts. Metallography analysis was used for grain size measurement while Computer Aided Cooling Curve Analysis was used for assessment of the undercooling and heat release values. In all instances, specimens treated with the cleaned master alloy showed smaller grains in the final structure and lower undercooling values. The difference in released heat between liquidus and recalescence temperatures was about 25% in specimens where added 0.66 wt% of cleaned master alloys compared to specimens where the commercial master alloys were added. Using cleaner Ti5B1 master alloy with a higher number of TiAl3 and TiB2 particles improves its grain refinement efficiency and transmits fewer impurities in produced parts. Producing cleaner master alloy would be beneficial from economic and environmental aspects by increasing its value and service time of produced parts besides simplifying the recycling process at the end of parts life-cycle.

AB  - Moving from fossil fuels toward renewable resources of energy has a worldwide consensus. Solar energy alone can satisfy all our energy requirements since the earth receives 725 ZJ of energy from the sun each year while total human energy consumption in 2019 was 0.584 ZJ. The 2010s are highlighted as a transitional decade when the photovoltaic conversion industry transformed from a subsidized to a profitable energy sector. While photovoltaic energy conversion is a clean process, technologies for producing photovoltaic materials and solar panels affect the environment. The utilization of photovoltaic materials with low impact on the environment during the entire life cycle will mark the beginning of the sustainable transition toward 100% clean renewable energy sources in a sustainable manner. Thus far, only perovskite compounds have the potential to satisfy these requirements because of their theoretical conversion efficiencies, ease of synthesis, production scalability, adaptability, and comparability to existing photovoltaic systems. In this article, the rise of the photovoltaic industry in the last decade is shown and requirements in further transition from renewable to clean sources of renewable energy are foreseen.

AB  - Due to tunable opto-electronic properties ZnO-based nanoparticles (ZnONPs) have been used for application in electronics, optoelectronics, photo(electro)catalysis, etc. Besides, as bio-inert, ZnONPs have a great potential in medicine for biosensing, bioimaging, drug and gene delivery, implants or as antimicrobial and anticancer agents. One of suggested governing mechanism of the biological activities of ZnONPs is based on the formation of reactive oxygen species (ROS). Actually, when ZnONP absorb photon with energy equal or greater than its band gap, electrons (e−) are excited from the valence band (VB) to the conduction band (CB) leaving the holes (h+) in VB. In following, the photogenerated h+ and e− migrate from bulk to surface. The photogenerated h+ at the VB react with water molecules adsorbed at the particle surface to produce hydroxyl radicals (OH•), while e− in CB react with oxygen molecules generating anionic superoxide radicals (O2−•). Radicals can be transformed in highly reactive hydroxyl radicals and so on. Derivatives of this active oxygen can damage the bacterial/tumor cells. However, in sufficiency ROS can damage normal cells as well. Thus, an understanding of ZnONPs crystal structure-activity relationship is crucial for the design of materials safe for application in treating diseases like cancer. In this study we established correlation between the surface-to-bulk defects ratio in ZnONPs and ROS formation. To vary surface-to-bulk defects ratio, series of ZnONP samples were synthesized by microwave processing of precipitate in the presence of a different amount (5, 10 and 20 wt.%) of surfactants, precisely, CTAB and citric acid. The particles crystallinity and phase purity were investigated by X-ray diffraction, Raman and FTIR spectroscopy. The particles morphology and texture properties were observed with FE–SEM and BET, respectively. The optical properties were studied using UV–Vis DRS and PL spectroscopy. ZnONP samples with different surface-to-bulk defect ratio were examined on ROS formation. Surface-to-bulk defect ratio in ZnONP was correlated with ROS formation, besides; their influence on cytotoxicity to normal and cancerous cells was comprehended.
