AB  - Sn-Pd electrocatalysts with a constant atomic ratio of 60 at.% Sn‒40 at.% Pd suitable for potential application in direct ethanol fuel cells were synthesized using a novel two-step electrodeposition method. First, Sn was electrodeposited in various forms of dendrites, from spear-like and needle-like to individual fern-like dendrites to a network of intertwined fern-like dendrites, by varying the cathodic potential and then performing electrodeposition of Pd at a constant current density in the second step. A morphological and elemental analysis of Sn and Sn-Pd electrocatalysts was performed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) techniques, while the size of Sn dendrites was analyzed using the particle size distribution (PSD) method. Cyclic voltammetry (CV) and chronoamperometry were applied in order to study the catalytic behavior of Sn-Pd electrocatalysts in the ethanol oxidation reaction (EOR), while CO stripping was used to estimate the antipoisoning capability of the electrocatalysts. The Sn surface morphology of the sub-layer was highly correlated with the electrocatalytic activity of the examined Sn-Pd electrocatalysts. The high activity it presented towards the EOR showed the suitability of the Sn-Pd electrocatalyst constructed from individual fern-like Sn dendrites as a sub-layer. Compared to Pd alone, this Sn-Pd catalyst showed more than 3 times higher activity and improved EOR kinetics. This enhancement in the catalytic activity of the Sn-Pd electrocatalysts is attributed to both the morphological characteristics of Sn as a sub-layer and the bifunctional effect.

AB  - Poly(vinylidenefluoride)–ZnO (PVDF–ZnO) nanocomposites with mechanically activated ZnO nanoparticle fillers were investigated using thermal and mechanical analysis and AFM and PFM. Differential scanning calorimetry (DSC) investigated the effect of ZnO nanoparticles on the crystallinity of the polymer, under controlled heating and cooling. Atomic force (AFM) microscopy was used to record the surfaces of the samples. Nanocomposite surface roughness shows the presence of the different phases inside of the matrix, where rough samples contain a higher proportion of the β phase. PFM was performed to investigate the piezoresponse of the composites. Nanoidentation showed that the mechanical activation of the filler (ZnO) increases the Young modulus with the activation time. Molecular simulations in periodic systems (PVDF–ZnO spherical nanocluster and nanocylinder composite) were used to investigate the influence of particle size and shape on the Young modulus of different phases of PVDF.

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  - This paper reports a detailed study of crystal structure and dielectric properties of ruthenium-substituted calcium-copper titanates (CaCu3Ti4−xRuxO12, CCTRO). A series of three samples with different stoichiometry was prepared: CaCu3Ti4−xRuxO12, x = 0, 1 and 4, abbreviated as CCTO, CCT3RO and CCRO, respectively. A detailed structural analysis of CCTRO samples was done by the Rietveld refinement of XRPD data. The results show that, regardless of whether Ti4+ or Ru4+ ions are placed in B crystallographic position in AA’3B4O12 (CaCu3Ti4−xRuxO12) unit cell, the crystal structure remains cubic with Im3¯ symmetry. Slight increases in the unit cell parameters, cell volume and interatomic distances indicate that Ru4+ ions with larger ionic radii (0.62 Å) than Ti4+ (0.605 Å) are incorporated in the CaCu3Ti4−xRuxO12 crystal lattice. The structural investigations were confirmed using TEM, HRTEM and ADF/STEM analyses, including EDXS elemental mapping. The effect of Ru atoms share in CaCu3Ti4−xRuxO12 samples on their electrical properties was determined by impedance and dielectric measurements. Results of dielectric measurements indicate that one atom of ruthenium per CaCu3Ti4−xRuxO12 unit cell transforms dielectric CCTO into conductive CCT3RO while preserving cubic crystal structure. Our findings about CCTO and CCT3RO ceramics promote them as ideal tandem to overcome the problem of stress on dielectric-electrode interfaces in capacitors.

AB  - Carbon materials derived from metal organic frameworks (MOF) have shown promising applications including energy storage and conversion, adsorption, gas storage and separation, catalysis, chemical sensing, and solid phase extraction. Here we present carbon materials derived from Al-based MOFs for use as electrodes in multivalent ion supercapacitors. Al MOFs were synthesized through complexation of fumaric acid with aluminum salts. Carbonization process of Al MOFs was followed by removal of Al2O3 via dissolving in NaOH solution. The properties of carbon materials were examined by X-ray diffraction (XRD), Thermogravimetric and Differential thermal analysis (TG/DTA), Fourier Infrared (FTIR) and Raman Spectroscopy, Particle Size Analysis (PSA), Scanning Electron Microscopy (SEM). The charge storage ability of carbon materials were examined in acidic and neutral aqueous solution using Cyclic Voltammetry at scan rates ranging from 5-500 mVs-1.

AB  - Immobilizing antifungal polyenes such as nystatin (Nys) and amphotericin B (AmB) into biodegradable formulations is advantageous compared to free drug administration providing sustained release, reduced dosing due to localized targeting and overall reduced systemic drug toxicity. In this study, we encapsulated Nys and AmB in medium chain length polyhydroxyalkanoates (mcl-PHA) microspheres (7–8 µm in diameter). The obtained formulations have been validated for antifungal activity in vitro against a panel of pathogenic fungi including species of Candida, Aspergillus, Microsporum and Trichophyton genera and toxicity and efficacy in vivo using the zebrafish model of disseminated candidiasis. While free polyenes, especially AmB, were highly toxic to zebrafish embryos at the effective (MIC) doses, after their loading into mcl-PHA microspheres, inner organ toxicity and teratogenicity associated with both drugs were not observed, even at 100 × MIC doses. The obtained mcl-PHA/polyene formulations have successfully eradicated C. albicans infection and showed an improved therapeutic profile in zebrafish by enhancing infected embryos survival. This approach is contributing to the antifungal arsenal as polyenes, although the first broad-spectrum antifungals on the market are still the gold standard for treatment of fungal infections.

AB  - A neuroprosthesis (NP) externally controls sensory and motor systems in persons with diminished sensation and movement control after a central nervous system injury or disease. An NP, based on peripheral functional electrical stimulation (FES) activates the ascending and descending neural pathways, thereby activates directly and reflexively muscles and activates centers in the CNS. The FES has an orthotic effect on paralyzed muscles and a carryover effect by decreasing the sensory and motor impairment. The carryover effect is maximized when FES is integrated into the mental and physical exercise of functional tasks during the acute phase of the disability. FES-based NP sends bursts of electrical charge pulses via electrodes and creates the pulsating electrical field in the targeted zones of the body. The externally generated pulsatile electrical field activates peripheral nerves that pass through these zones. These externally generated action potentials travel along the peripheral nerves to muscles and to the central nervous system. The most apparent FES results when applied to the peripheral nervous system (PNS) are the restoration of the standing and walking (postural control), generation of cyclic movements suitable for pedaling, and manipulation and grasping. The activation of afferent neural pathways contributes to the increased inflow of action potentials to the central nervous system and increases the central nervous system (CNS) excitability. The significant effect of FES of peripheral nerves is the prevention and reduction of secondary complications of paralysis (e.g., cardiovascular deterioration, loss of muscle bulk and strength, decubitus, diminished gastric and urinary functioning, reduced range of movement in joints, spasticity, etc.).

An X-ray powder diffraction is used to examine the crystal structure, while scanning electron microscopy is used to reveal the morphology of the powder. The crystal structure refinement is performed in the P4/nmmZ space group. The electrochemical intercalation of several cations (Na+, Mg2+, Ca2+, and Al3+) in saturated nitrate aqueous solutions is investigated. The most notable reversible activity is found for the cycling in aluminium nitrate aqueous solution in the voltage range from −0.1 to 0.8 V vs. SCE. During the preparation of the electrode, it is observed that the structure is prone to changes that have not been recorded in the literature so far. Namely, the use of conventional binder PVDF in NMP solution deteriorates the structure and lowers the powder’s crystallinity, while the use of Nafion solution causes the rearrangement of the atoms in a new crystal form that can be described in the monoclinic P21/c space group. Consequently, these structural changes affect electrochemical performances. The observed differences in electrochemical performances are a result of structural rearrangements.

AB  - The capacitance and operating voltage of supercapacitors as well as their energy density have been increased by development of different materials and electrolytes. In this paper, two strategies, for the first time, were used to improve energy density: Mn3O4- and N-dual doped carbon electrode and aqueous mixture of multivalent ions as electrolyte. Mn3O4- and N-dual doped carbon was prepared by a novel and cost-effective procedure using deep eutectic solvent. XRD, XPS, and FTIR confirmed presence of Mn3O4 and nitrogen, while SEM and EDS elemental mapping showed micrometer-sized nanosheets with uniform distribution of C, O, N, and Mn atoms. Charge storage behavior of carbon was tested in aqueous multivalent-based electrolytes and their mixture (Ca2+-Al3+). Regarding both specific capacitance and workable voltage, the Ca2+-Al3+ mixed electrolyte was found as the best optimal solution. The calcium addition to the Al-electrolyte allows the higher operating voltage than in the case of individual Al(NO3)3 electrolyte while the addition of Al3+ ion in the Ca(NO3)2 electrolyte improves the multivalent-ion charge storage ability of carbon. As a result, the specific energy density of two-electrode Mn3O4@N-doped carbon//Al(NO3)2+Ca(NO3)2//Mn3O4@N-doped carbon supercapacitor (34 Wh kg−1 at 0.1 A g−1) overpasses the reported values obtained for Mn-based carbon supercapacitors using conventional aqueous electrolytes.

abstract = "The capacitance and operating voltage of supercapacitors as well as their energy density have been increased by development of different materials and electrolytes. In this paper, two strategies, for the first time, were used to improve energy density: Mn3O4- and N-dual doped carbon electrode and aqueous mixture of multivalent ions as electrolyte. Mn3O4- and N-dual doped carbon was prepared by a novel and cost-effective procedure using deep eutectic solvent. XRD, XPS, and FTIR confirmed presence of Mn3O4 and nitrogen, while SEM and EDS elemental mapping showed micrometer-sized nanosheets with uniform distribution of C, O, N, and Mn atoms. Charge storage behavior of carbon was tested in aqueous multivalent-based electrolytes and their mixture (Ca2+-Al3+). Regarding both specific capacitance and workable voltage, the Ca2+-Al3+ mixed electrolyte was found as the best optimal solution. The calcium addition to the Al-electrolyte allows the higher operating voltage than in the case of individual Al(NO3)3 electrolyte while the addition of Al3+ ion in the Ca(NO3)2 electrolyte improves the multivalent-ion charge storage ability of carbon.

AB  - FeCoV alloys with high saturation magnetization and high Curie temperature, making them useful for high-temperature and power-dense applications (e. g. aviation device). In this study, we report the results of observing the structural properties of 49Fe49Co2V alloy produced by PIM / MIM technology. The starting granulate was prepared by mixing FeCoV powder with a low-viscosity binder. After injection, the raw “green” samples were first treated with a solvent and then thermally with the same aim of removing the binder. MIM technology is completed by high-temperature sintering of “brown” samples for 3.5 hours at temperatures from 1370 OC to 1460 OC in a hydrogen atmosphere, which provides the necessary magnetic and mechanical characteristics. Depending on the sintering temperature, structural parameters of particle size Dmax, Feret X, Feret Y were investigated and analysed.

AB  - Up-conversion properties of SrGd2O4 nanoparticles co-doped with different Yb3+ and constant Er3+ ions were successfully prepared via sol- gel assisted combustion. Rietveld refinement and scanning/transmission electron microscopy with corresponding energydispersive X-ray spectroscopy revealed that obtained powders are composed of agglomerated nanoparticles with orthorhombic (Pnma) structure that have a uniform distribution of all constituting elements. Photoluminescence measurements implied intensification of the upconversion (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 efficiency (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 200W/cm2).

AB  - Perovskite ceramic material based on MgTiO3 is used in various types of electronic devices owing to its dielectric properties, high dielectric constant, and low losses. These features can be tailored by setting preparation conditions. Densification of magnesium titanate by Spark Plasma Sintering (SPS) was the aim of this work. First, the mechanical activation in the highenergy ball mill was applied on the powder of MgO-TiO2 mixed in mole ratio 1:1. Prepared powder mixtures, activated for different times, were SPS sintered, at 1200 oC with a heating rate of 100oC/min. After reaching the desired temperature, a uniaxial pressure of 50 MPa was applied, and dwelled at this condition for 5 min, followed by cooling to room temperature at 5oC/min. The starting powders, activated mixtures, and sintered ceramics bodies were investigated by X-ray diffraction, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The presence of the MgTi2O5 phase was noticed for the nonmilled ceramics. In the samples obtained from milled powders, MgTi2O5 was detected in EDS spectra in a lower amount, below the threshold of the XRD method. Dielectric measurements were performed at a wide range of frequencies and temperatures. The highest value of the hardness was obtained from powder milled for 15 min before SPS.

AB  - Powdery mixtures of 50 mass% Fe, 4 mass% Pb, 3 mass% Zr and 43 mass% BaTiO3 were mechanochemically activated via planetary ball mill for time periods spanning from 30 min to 300 min and subsequently sintered for 2 hours at 1200 °C in the dynamic atmosphere of air. Of all the samples, the one activated for 270 min exibited the most prominent piezoelectric effect of up to 1.17 mV under the applied pressure of 113 kPa with the relaxation time of 85 s. The pressure dependence of voltage showed three successive, distinct domains in which the voltage rise differed, with the rate of 0.09 mV/kPa in the initial one (ranging from 0.00 kPa to 5.66 kPa of the external pressure), 0.01 mV/kPa in the second one (from 5.66 kPa to 56.60 kPa) and ultimately the plateau occuring from approximately 60 kPa onwards. When heated to 200 °C, the same sample manifested the biggest pyroelectric effect as well, being 0.55 mV with no external field applied, as well as 1.04 mV when subjected to the homogenous magnetic field of 50 kA/m, thus yielding a 89% net increase of the incited voltage observed.

AB  - Hydroxyapatite (HAp) attracts great attention due to application in reconstructive medicine for hard tissues, mostly bones and teeth, where it is declared to be highly biocompatible material. Its grafting with amino acids further increases biocompatibility and has crucial importance for acceptance of body implants. In this work different methods of grafting were investigated: simple mixing, thermal treatment induction and in situ synthesis/grafting reactions. Two amino acid precursors were separately tested in grafting procedures: pure alanine and alanine methyl ester hydrochloride. The efficiency of grafting was determined based on X-ray powder diffraction (XRPD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermal analyses (DSC, TG/DTA) of obtained powders, while complementary UV-VIS spectroscopy of supernatants was additionally performed for quantitative determination of non-grafted nitrogen using ninhydrin standardized procedure.

AB  - Optically active materials have a wide range of applications. The phenomenon of light conversion includes two main types: up-conversion, which is the ability of convertion lower energy photons into the ones with the higher energy, and down-conversion, which is vice versa. Orthorhorhombic SrGd2O4 doped with rare earth elements is established to have promising optical characteristics, but rarely explored until nowadays as up-converting material. Due to the phonon energy of around 475 cm-1, which is lower than in many other compounds commonly used hosts, this one has a great perspective as an optically active material. Here, for the first time two combinations of rare earth dopant ions, Yb3+/Ho3+ and Yb3+/Tm3+, with different mutual ratios were chosen as pairs for inducing up-conversion. Sol-gel assisted combustion synthesis, which comprises citric acid as chelator and glycine as fuel, was used to obtain powdered samples that are subsequently thermally treated for 3.5 h at 1100°C. X-ray powder diffraction analysis (XRPD) was performed to determine crystal structure. Morphology characteristics were observed by scanning and transmission electron microscopy (SEM/TEM). Photoluminescent up-converting properties were measured in function of laser power (976 nm) in order to define optimal doping concentration and upconversion mechanism.

AB  - Conversion of solar energy into hydrogen energy via the water-splitting process, assisted by photo-semiconductor catalysts, is one of the most promising technologies for the future because large quantities of hydrogen can be generated in a clean and sustainable manner. Zinc oxide (ZnO) represents one of the most investigated photocatalyst. Its ability to overcome the limitations of pristine ZnO through enhanced visible light absorption and reduced recombination of photogenerated charge carriers have gathered the attention of the many research groups. Numerous studies enabled understanding its greater activities and most studies reveal that reactive oxygen species (ROS), oxygen vacancies (Ov) and zinc interstitials (Zni) are responsible for the enhanced photoactivity. In fact, different factors like defect concentration, defect location, valence and conduction band levels play a key role in the working mechanisms of ZnO material. Materials with the perovskite crystal structure such as BaTiO3 (BT) and BaTi1–XSnXO3 (BTS) found application in the construction of the active layer of the solar cell, in which the photogenerative electrons are generated. The environmental instability of perovskite solar cells caused by the ultraviolet photocatalytic effect of metal oxide layers is a critical issue that must be solved. Possible solution with improved environmental stability can be synthesis of ZnO composite heterojunction perovskite solar cells. In this study photo(electro) catalytic properties of: BT and BTS were compared with those of ZnO@BT and ZnO@BTS, respectively. In both cases the ZnO@BT and ZnO@BTS composite materials revealed enhanced photo(electro) catalytic activity as compared to the pristine BT and BTS materials. In order to investigate the origin of the enhancement, the pristine metal oxides and composites were characterized using a variety of techniques, including X-ray diffraction (XRD), Raman, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE SEM), UV-Vis diffuse reflectance spectroscopy and linear voltammetry process.

AB  - The aim of this study was to investigate the influence of the deposition of vanadium oxide epitaxial layer on the photoresponse of TiO2/CH3NH3PbI3 heterojunction. TiO2 nanotube array was synthesized via anodization of titanium foil at three different voltages. After annealing at 450 °C, vanadium oxide was deposited by direct deposition from vanadyl(IV) sulfate solution. Microstructure analysis has been used for the investigation of the influence of different voltages of anodization on tube diameter. Spectroscopy measurements pointed out the red shift in diffusion reflectance spectra after deposition of vanadium oxide. The presence of V5+ oxidation state has been detected on the surface of nanotube arrays by chemical analysis. CH3NH3PbI3 monocrystal was dry pressed on top of the nanotubes in order to make a photodiode. The current-voltage characteristics of the photodiode were recorded and it was observed that the sample with the smallest wall thickness and higher amount of vanadium has the best photocurrent response.

AB  - Introduction: Cerebral hypoperfusion (CH), a reduced cerebral blood flow, characteristic for aging and neurodegenerative disorders, might be associated with a pro-oxidative state in the brain due to the generation of reactive oxygen species (ROS) that cause neuronal damage. These overgenerated pro-oxidants might be reduced, disabled and neutralized by the endogenous antioxidant enzymes, including superoxide dismutase (SOD) and catalase (CAT). A sex steroid hormone, progesterone, in several experimental models of neuronal injury exerts anti-oxidative properties upregulating anti-oxidative molecules and thus promoting neuroprotection. However, its efficacy in the state of CH is still unknown and it is necessary to better understand the mechanism underlying this hormone’s neuroprotective effects.
Aim: We investigated whether progesterone is able to modulate CH-induced pro-oxidative/anti-oxidative imbalance, as well as SOD and CAT activities, in the prefrontal cortex of three-month-old male Wistar rats subjected to permanent bilateral common carotid artery occlusion (2VO).
Methods: The appropriate actions were undertaken to reduce the distress of the animals in agreement with the European Community Council Directive of 86/609/EEC and 010/63/EU for animal experiments. All experimental procedures were allowed by the Ethical Committee for the Use of Laboratory Animals of VINČA Institute of Nuclear Sciences - National Institute of thе Republic of Serbia, University of Belgrade, Belgrade, Republic of Serbia (protocol authorization numbers 02/11 and 323-07-04253/2016-05). Following chloral hydrate anaesthesia, 8 rats randomly assigned in 2VO groups were double occluded with 5–0 silk suture, while 4 animals from sham operated group were subjected to the same surgical procedure but without actual ligation of carotid arteries. Four hours following the surgical procedure animals from sham operated group, used as controls, were subcutaneously treated with vehicle (commercial flax oil, 1 mg/kg/day, S + V), while animals in 2VO groups were subjected to either progesterone (1.7 mg/kg/day, 2VO + P) or vehicle (commercial flax oil, 1 mg/kg/day, 2VO + V). Following 7 days lasting treatments, pro-oxidative/anti-oxidative balance was assessed according to the method of Alamdari et al. [1]; while activities of anti-oxidative enzymes were determined as described in the study by Tatalović et al. [2]. One-way analysis of variance (ANOVA) test followed by Tukey’s post hoc test was employed to analyse data. The values of p < 0.05 or less were considered statistically significant.
Results: Obtained results demonstrate that compared to controls, 2VO and vehicle treatment induced a significant increase of pro-oxidants levels (p < 0.01) as well as the activities of both investigated anti-oxidative enzymes, although only the CAT activity was significantly increased (p < 0.05). Following progesterone treatment, pro-oxidants levels were lowered to the control level which caused the difference between the 2VO groups (p < 0.05). In parallel, no statistically significant change in SOD activity was observed, while CAT was upregulated (p < 0.05).
Conclusion: Presented results suggest that in the prefrontal cortex in the state of CH, progesterone, by modulating the CAT activity, downregulates overgenerated reactive species, reduces CH-induced oxidative stress and exerts anti-oxidative outcomes.

AB  - Introduction: As a result of human activity, the amount of plastic waste has increased immensely in the environment. While the main concern has been orientated toward visible litter, more recently fragments of plastic less than 5 mm in diameter, called microplastic particles (MP), raised the attention due to their ability to induce toxic effects in organisms. The toxicity of MP increases with a decrease in size since smaller sized particles are absorbed systematically and accumulated in different organs/tissues, including brain.

Aim: Present study is designed to compare possible toxic acute effects of different sized MP, originating from polyethylene-terephthalate bottles, on toxicity signs, sensory-motor functions and relative brain weight in young male Wistar rats.

Methods: Rats (n = 24) were divided in four experimental groups: (I) intact (controls); Q that orally received a 2.5 ml of Milli-Q; P1/P2 that were respectively orally administrated with 35 mg/kg of MP in median diameter of either 40 or 70 μm dissolved in a 2.5 ml of Milli-Q. 24 h after treatments, using toxicity clinical test, we assessed the agitation, convulsion, piloerection, sleepiness and lethargy. Parameters were valued as: – (no effect), + (mild effect), ++ (moderate effect) and +++ (major effect). Then, we evaluated sensory-motor functions by monitoring: consciousness (scored 0/1 point), respiration (scored 0/1), spontaneous activity (scored 0/1/2/3), forepaw outstretching (scored 0/1/2), climbing (scored 0/1), visual placing (scored 0/1), cage grasp (scored 0/1), gait posture (scored 0/1/2), geotaxis (scored 0/1), hearing (scored 0/1) and pacing/circling (scored 0/1). Total score was expressed as the sum of average scores of all investigated parameters and graded on the scale from 0 to 15. Then, rats were weighed and sacrificed, while their brains were carefully removed and weighed. The relative brain weights were calculated as the ratio of brain (wet tissue, mg) weight to body weight (g). For toxicity clinical testing a descriptive analysis was used while other data were analysed by One-way analysis of variance followed by Tukey’s posthoc test. Results were considered significant at p < 0.05.
Results: Clinical toxicity signs were similar between groups while results of sensory-motor test point to unaltered sensory-motor functions upon MP treatments compared to controls (F (3, 20) = 0.9538; P = 0.4336). The absence of changes might be attributed to acute treatment, brief evaluation period and lack of cumulative effect upon MP treatments. Nonetheless, only smaller sized MP led to an increase in relative brain weight compared to controls (F (3, 20) = 3.425; P = 0.0369; p < 0.05) which might indicate the capability of smaller sized MP to cross blood-brain barrier and be accumulated in the brain inducing oxidative stress and inflammatory response. Although larger sized MP did not cause changes in relative brain weight, the possible modulations of additional parameters that were not the focus of this study should not be omitted.
Conclusion: According to the presented results, even a smaller sized MP applied in a single dose could be harmful to health, thus, greater control of plastic usage and disposal is essential for humanity.

AB  - In the brain, three isoforms of nitric oxide synthase (NOS) regulate production of nitric oxide (NO), a signalling molecule with a role in cerebral blood flow regulation. Depending on the stimulus, NO exerts dual nature, from neuroprotective to neurodestructive. Given the scarcity of literature data on the involvement of nitrosative stress indicators in the rat hippocampal response to 7-day lasting progesterone (P4) treatment following permanent occlusion of both common carotid arteries, we assessed NO level and protein expressions of endothelial nitric oxide synthase (eNOS, including its total (t-eNOS) and phosphorylated at Ser1177 isoform (p-eNOS Ser1177)). According to obtained results, elevated NO levels occurred due to activity of other NOS forms since eNOS expressions were similar between experimental groups. Although NO level was downscaled it was still elevated in occluded animals treated with P4, showing modest anti-nitrosative effect of this potent steroid in the hippocampus.

AB  - Nanosized CoMoO4 solid solution was successfully synthesized at room temperature using simple and fast Self Propagating Room Temperature procedure (SPRT). The structural, textural, morphological and surface characteristics of the nanosized CoMoO4 were examined in detail by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, Field emission scanning electron microscopy (FESEM), and nitrogen sorption method. X-ray powder diffraction (XRPD) reflected the presence of two different phases that are in the same space group. The α-CoMoO4 and the β-CoMoO4 modification crystallizes in the monoclinic space group C2/m, No.12, but the β-phase clearly distinct from the α-phase due to the tetrahedral coordination of the Mo6+ ions. Adsorption tests were studied over CoMoO4 nanopowders under different experimental conditions (material dosage, initial concentration of pollutant textile dye, etc). The obtained results showed acceptable sorption characteristics of the material.

AB  - Nanocrystalline powders of Ca1-xGdxMnO3 (x=0.05, 0.1, 0.15, and 0.2) have been synthesized by the modified glycine nitrate procedure and pressed into pellets that served as green bodies for a systematic investigation on their structural and microstructural properties [1]. Dilatometric measurements were performed in order to confirm the optimal sintering temperature. Dilatometric curves, besides sintering, are recording superimposed phase transition and linear expansion. Using a dilatometric curve, three temperatures were determined at which the examined sample shows significant changes. At 1055 °C–1194 °C certain second order phase transition is evident, at 1365 °C–1409 °C intensive nitrogen oxide extrusion, and in duration of 86 min at 877 °C heating ramp thorough isothermal holding at 1410 °C until 158 min cooling schedule at 1331 °C sintering is performed. Vickers hardness values were obtained based on the change in the surface area of the diamond pyramid. The results indicate that the hardness of the Ca1-xGdxMnO3 system (x = 0.05; 0.1; 0.15; 0.2) is not conditioned by the amount of doped gadolinium.
