AB  - The B4C-SiC composites were obtained through densification of B4C and β-SiC powders with different ratios using Spark Plasma Sintering (SPS). Thermal treatment was conducted in the 1850–2000 °C temperature range under pressure of 70 MPa. Starting powder ratio effect on sintering behavior, relative density, microstructural development, and mechanical properties of obtained composites was investigated. Results showed that only starting compounds were observed in sintered ceramics with uniformly distributed and densely compacted B4C and SiC grains. Maximal relative density (100 %) was achieved for 25 % B4C-75 % SiC sample densified at 2000 °C. Obtained composites' microhardness ranged from 33 to 43 GPa, depending on constituents' content and densification temperature. Maximal microhardness was achieved for composite with the maximal amount (75 %) of B4C densified at 2000 °C. Composites' behavior in extreme conditions was evaluated through their interactions with laser beam and obtained results showed that SPS is effective densification method for obtainment of additive-free B4C-SiC composites applicable in extreme radiation environments.

AB  - The interfacial charge transfer (ICT) complex formation between zirconium dioxide (ZrO2), the material absorbing below 250 nm, and 5-aminosalicylic acid (5-ASA) leads to the formation of visible-light-absorbing inorganic–organic hybrids. The free amino groups, present on the hybrid's surface after the ICT complex formation, were used to reduce silver ions and link silver particles to ZrO2. The prepared samples were characterized by using transmission electron microscopy, X-ray diffraction analysis, and nitrogen adsorption–desorption isotherms. Density functional theory (DFT) calculations using a cluster model are applied to explain optical changes in hybrids, i.e., absorption redshift induced by the ICT complex formation. Decolorization of an organic dye crystal violet (CV), under ultraviolet-C or visible light, was used to compare the photocatalytic ability of the prepared samples. The ICT complex formation transformed ZrO2 into a hybrid material able to induce photocatalytic reactions under exclusive visible light excitation.

AB  - Background: Although luteolin has been confirmed as potent anticancer agent, its potential application as therapeutic is limited by its water solubility. To overcome this shortcoming nanoparticle technology approach was applied. Owing to their proven low toxicity and the possibility to be easily functionalized gold nanoparticles (AuNP) were the nanosystem of choice used in this study. Novel luteolin capped gold nanoparticles (AuNPL) were synthesized and their anticancer effect towards human cervical adenocarcinoma HeLa cells was investigated in vitro. Methods: AuNPL were synthesized by reducing chloroauric acid by trisodium citrate with subsequent addition of luteoline during synthesis and their physicochemical characterization was done. AuNPL cytotoxicity against HeLa, human malignant melanoma A375, and normal human keratinocytes HaCaT cells was tested by MTT cell survival assay, and their IC50 values were determined. The capability of AuNPL to induce cell cycle arrest and apoptosis in HeLa cells were demonstrated by flow cytometry. The antioxidant activity of AuNPL was assessed by DPPH⋅ and ABTS⋅þ scavenging assays. Cytoprotective properties of AuNPL towards HaCaT cells were examined by measuring the physiological and H2O2 induced intracellular reactive oxygen species (ROS) levels using flow cytometry. Also, genotoxicity of AuNPL in HaCaT cells was investigated by the single cell alkaline comet assay. Results: Spherical AuNPL, stable in aqueous solution up to six months at 4 ◦C were obtained in the synthesis. The selectivity in the cytotoxic action of AuNPL on HeLa and A375 cancer cells compared with their cytotoxicity on normal keratinocytes HaCaT was observed. AuNPL exerted their cytotoxic activity against HeLa cells through accumulation of the cells in the subG1 phase of the cell cycle, inducing the apoptotic cell death mediated by the activation of caspase-3 − 8, and − 9. AuNPL antioxidative potential was confirmed by DPPH⋅ and ABTS⋅þ scavenging assays. IC50 concentration of AuNPL exerted cytoprotective effect against HaCaT cells by the significant reduction of the physiological intracellular ROS level. Additionally, AuNPL were shown as more cytoprotective towards HaCaT cells then luteolin due to the more successful elimination of H2O2 induced intracellular ROS. Moreover, nontoxic concentrations of AuNPL did not cause considerable DNA damage of HaCaT cells, indicating low genotoxicity of the nanoparticles.

AB  - This work presents the perspective of applying the laser desorption/ionization mass spectrometry (LDI MS) for characterization the anode film of the Ag60Cu26Zn14, Ag58.5Cu31.5Pd10, and Ag63Cu27In10 alloys (at high concentrations of chloride ions in solutions). The reference LDI mass spectra of anode films of pure Ag and Cu have been used for the identification of product corrosion. Knowing the clusters detected in the reference spectra lead to the facilitating identification of the LDI mass spectrum of the sample and reduces the analysis time. The LDI MS analysis of these alloys revealed that the predominant corrosion product are AgCl (from AgnCln+1−/+, n = 1–3), and CuCl (from “superhalogen” CumCln− clusters, m = 1–2, n = 2–6); it also revealed Cu2(OH)3Cl (from Cu2(OH)(H2O)2+) and Cu2O (from Cu(H2O)+, Cu2O doped with chlorine). These results are in accordance with the X-ray diffraction and Raman analysis. The LDI MS spectra of alloys contain the additional peaks formed due to the mutual influences of different metals in the alloys (AgCuCl3− (AgCl-CuCl2−), AgCu2Cl4− (AgCl-CuCl-CuCl2−), and Ag2CuCl4− (AgCl-AgCl-CuCl−), which is consistent with the identified corrosion products. It should be noted that the LDI MS suggest the presence of CuCl2, which can be interpreted as the corrosion products retained in the porous films of alloys, and not detected by the other methods due to a small amount. The future theoretical and experimental studies of metal clusters, significant for metallurgy, can contribute that the LDI MS is becoming a powerful analytical tool for characterization the metal surfaces.

AB  - In this work, the basalt deposits site from southern Serbia was used as a matrix for the composite materials. The corrosion behavior of basalt matrix composites with various ratios of commercial stainless steel 316L (5, 10, 15, and 20 wt.%) and bulk basalt produced by sintering in the air (t=1060ºC and τ=60 min) were studied by immersion corrosion technique. The samples were immersed in a solution of artificial acid rain H2SO4:HNO3 = 9:1 at ≈ pH 3 to measure the concentration of released metal ions using inductively coupled plasma-optical emission spectrometry (ICP-OES). The elements Fe, Cr, Mn, and Ni were monitored, while the others were below the limit of quantification. The concentrations of the metal ions in the solution were studied over 15 weeks. The ions release rate from all the sintered samples was found to follow the Weibull cumulative distribution function (CDF). This means that the release rate changes over time and allows us to calculate the characteristic times of ion release. The changes in the samples were monitored by light microscopy (LM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and weight loss. Sintered basalt shows high resistance to corrosion with a characteristic time of about 18 years for Fe and more than 25 years for Cr and Mn. The weight difference between the initial and after 15 weeks of exposure to the solution (sintered basalt) was not observed. On the other hand, the presence of 5 wt.% steel powder in the sintered basalt accelerates the release of metal ions by about six times. When the steel powder content in the composite materials increases, the metal release rate does not change further, but a weight loss is observed. The characteristic times for Fe, Cr, Ni, and Mn in composite materials are about 5 years. These composite materials can be investigated as materials for using in an acid environment.

AB  - Ceramic materials are often used in very aggressive and corrosive environments due to their high chemical inertness and corrosion resistance. However, even if corrosion progresses slowly, it still occurs. Corrosion usually depends on the structural properties of the materials. For example, more compact or tightly bonded materials corrode less, whether glass or crystalline materials. With the dramatic increase in nitrogen and sulphide oxide emissions, acid rain pollution has become one of the world's biggest environmental problems. One of the methods used to measure the corrosion resistance of ceramic materials and ceramic matrix composites (CMCs) is the immersion method, which studies their behaviour by immersing them in corrosive media and measuring the concentration of ions released. Adding different particles to basalt before sintering to obtain CMCs can increase fracture toughness. The aim of this work was to investigate the effects of the content of 316L stainless steel powder in sintered basalt on its structural properties and resistance to the release of metal ions in acidic environments. The andesite-basalt-based samples were prepared by adding 5, 10, 15, and 20 wt.% of steel powder, respectively, before sintering. The basalt aggregate and the pure sintered basalt served as reference materials. The metal concentrations in the solution were studied for 15 weeks at room temperature and a pH of 3.13±0.01. The major elements Fe, Cr, Mn, and Ni were monitored, while the others were below the limit of quantification. We found that the concentration of metal ions released from the basalt aggregate increases exponentially, implying that the release rate is constant over time. However, the concentration of metal ions released from the sintered samples follows the Weibull cumulative distribution function (CDF), which means that the release rate changes over time and allows us to calculate the characteristic times of ion release. The presence of 5 wt.% steel powder in the sintered basalt accelerates the release of metal ions by about six times. If the steel powder content increases, the metal release rate does not change further. These findings are positive since the highest toughness of sintered basalt is expressed at 20 wt.% of steel powder. The corrosion stability of glass-ceramic-metal-based composites was found to be satisfactory compared to natural andesite-basalt aggregate. These composites can be used in conditions of acid rain exposure where higher fracture toughness is required.

abstract = "Ceramic materials are often used in very aggressive and corrosive environments due to their high chemical inertness and corrosion resistance. However, even if corrosion progresses slowly, it still occurs. Corrosion usually depends on the structural properties of the materials. For example, more compact or tightly bonded materials corrode less, whether glass or crystalline materials. With the dramatic increase in nitrogen and sulphide oxide emissions, acid rain pollution has become one of the world's biggest environmental problems. One of the methods used to measure the corrosion resistance of ceramic materials and ceramic matrix composites (CMCs) is the immersion method, which studies their behaviour by immersing them in corrosive media and measuring the concentration of ions released. Adding different particles to basalt before sintering to obtain CMCs can increase fracture toughness. The aim of this work was to investigate the effects of the content of 316L stainless steel powder in sintered basalt on its structural properties and resistance to the release of metal ions in acidic environments. The andesite-basalt-based samples were prepared by adding 5, 10, 15, and 20 wt.% of steel powder, respectively, before sintering. The basalt aggregate and the pure sintered basalt served as reference materials. The metal concentrations in the solution were studied for 15 weeks at room temperature and a pH of 3.13±0.01. The major elements Fe, Cr, Mn, and Ni were monitored, while the others were below the limit of quantification.

AB  - Mnogi teorijski proračuni su pokazali da su litijumom dekorisni borani (BxHy) ili klasteri bora (Bn) potencijalni materijali za skladištenje vodonika. Pored toga, pokazalo se da klasteri litijumfluorida poboljšavaju kapacitet skladištenja vodonika bolje od samog litijuma. Međutim, broj eksperimentalnih studija je mnogo manji. Zbog toga je u ovom radu ispitivana mogućnost interakcije klastera litijuma ili litijumfluorida sa boranima, metodom laserske desorpcione/jonizacione masenespektrometrije (LDI MS).

AB  - Cover crops play an important role in low-input cropping systems, increasing the use of agro-ecosystem services. Due to the lack of information about the impact of cover crops and bio-fertilizers on popcorn maize (Zea mays everta Sturt.) growth and yield quality, especially the popping volume and nutritive quality, such as concentrations of protein and mineral elements, this research aimed to provide essential information. The interrelation between popcorn maize productivity and quality with important groups of soil microorganisms presents additional novelty. The results demonstrated that field pea is a beneficial cover crop, especially when combined with a bio-fertilizer, supporting the accumulation of maize biomass, chlorophyll, yield potential, and the concentrations of protein, Ca, Mg, Fe, and Zn. In addition, field pea residues promoted N-fixing bacteria, and the number of total microorganisms, especially actinomycetes and decomposing bacteria, which could promote nutrient uptake and grain quality. Residues of cover crop mixtures, common vetch + winter oats and field pea + winter oats, promoted the total number of microorganisms in the soil, and up to the end of vegetation, a greater number of decomposition and ammonification microorganisms were found, especially when the bio-fertilizer was applied, which consequently could support greater maize biomass. Popping volume, as a main trait of popcorn maize, had the highest value in the common vetch + winter oats variant, supporting again the statement that quality traits could be enhanced in sustainable production. Unlike living cover crops, mulch mainly affected soil microbial communities and promoted the development of actinomycetes and cellulolytic microorganisms during the growing season. The results of this research could contribute to the development of sustainable popcorn maize production for improved grain quality. They could also serve as a basis for isolating beneficial soil microorganisms to develop new bio-fertilizers that could improve maize production in synergy with cover crops.

AB  - In the last couple of decades the scientific is making great efforts to investigate the phenomenon of laser-matter interaction, because these knowledge can directly positively influence on technological innovations in the field of materials. This phenomenon are still not fully invetigate since involves a number physical and chemical processes, which take place simultaneously or separated in time and space [1]. The laser desorption/ionization (LDI) implies the following processes: the laser provide a pulse of energy to sample (for a few ns), the sample increases in temperature quickly ( to several thousand degrees), so lead to the production ions, neutrals and electrons in the gass phase [2]. The aim of this paper is to examine the products of the gas phase formed during the interaction of laser- Li1.999Ta0.005SiO3. The Li1.999Ta0.005SiO3 ceramics has a wide application because the melting of lithium metasilicate is used for the calibration of thermocouples, as a flux in glazes and ceramic enamels, dental glass, nuclear waste immobilization as well as ceramic materials for fusion reactors. The knowledge gained should contribute to a better understanding behavior of Li1.999Ta0.005SiO3 in extreme conditions. The experiments were performed on a commercial matrix-assisted laser desorption/ionization mass spectrometer (MALDI MS) with time of flight mass analyzer (Voyager-DE PRO, Sciex, USA), equipped with a nitrogen pulse laser (pulse duration of 3 ns, 20 Hz, and wavelength of 337 nm). The mass spectra were obtained using the LDI (without matrices) positive and negative reflector modes. It is known that the LDI MS is an efficient method for the production and detection of homogeneous and heterogeneous clusters [3]. Preliminary results shows that the ion signals in the negative ion LDI mass spectrum of Li1.999Ta0.005SiO3 correspond to the following species: m/z 59.89 SiO2 -  (calcd 59.97), m/z 71.90 Si2O-  (calcd 71.95), m/z 83.90 Si3 -  (calcd 83.93), m/z 95.91 Si(OH)4 - (calcd 95.99), m/z107.91 Si2(OH)2(H2O)-  (calcd 107.97), m/z 119.92 Si2O4 -  (calcd 119.93), m/z 120.95 Si2O3(OH)-  (calcd 120.94), m/z 131.93 Si3O3 -  (calcd 131.92), m/z 143.92 Si2(OH)2(H2O)3 - (calcd 143.99). The ion signals in the positive mode were attributed to the following cations: LiSi(OH)+  (m/z 52.02, calcd 51.99), Li3(OH)(H2O)+ (m/z 56.04, calcd 56.06), Li2SiO+ (m/z 58.05 calcd 58.00), Li3Si2H2(H2O)+ (m/z 97.15 calcd 97.03), Li5Si2H2O+ (m/z 109.10, calcd 109.04). The results show that silicon-oxygen cluster ions were formed in the negative mode, while lithiumsilicon clusters were detected in the positive mode.

AB  - Organic agriculture offers many benefits through the increased nutritional quality of produced crops, agro-ecosystem preservation, and climate change mitigation. The development of an efficient nutrient management strategy in low-input systems, such as organic agriculture, which supports soil fertility and essential nutrients absorption by crops, is continually exploring. Thus, a study with maize–spelt–soybean rotation during a 5-year period in organic production was established to evaluate the variability in soil organic matter (SOM) and the status of available elements: N, P, K, Ca, Mg, Fe, Cu, Mn, Zn, and Si from the soil, as well as grain yield (GY) and the content of protein, P, K, Ca, Mg, Fe, Cu, Mn, Zn, and Si concentration in the grain of spelt, maize, and soybean. Significant variations in mineral elements in the soil, GY, and grain composition were detected. Spelt achieved the highest average GY, while soybean grain was the richest in a majority of examined nutrients. The soil Ca content was important for GY, while the protein level in grain was generally tied to the Mn level in the soil. It was recognized that soil–crop crosstalk is an important strategy for macro- and micro-nutrients management in the soil and grain of organically produced spelt, maize, and soybean. While a reduction in the GY and protein concentration in grain was present over time, it was established that a low-input system under dry-farming conditions supports nutrient availability and accumulation in grain, under semi-arid agro-ecological conditions of central Serbia.

AB  - Maize is an important staple crop and a significant source of various nutrients.We aimed to determine the macronutrients, antioxidants, and essentialelements in maize genotypes (white, yellow, and red kernel) using threedifferent fertilizers, which could be used as a basis to increase the nutrientdensity of maize. The fertilizer treatments used bio- and organic fertilizers as asustainable approach, urea, as a commonly used mineral fertilizer, and thecontrol (no fertilization). We evaluated the yield, concentration ofmacronutrient (protein, oil, and starch), nonenzymatic antioxidants(phenolics, yellow pigment, total glutathione (GSH), and phytic phosphorus),and reduction capacity of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, aswell as essential elements that are commonly deficient in the diet (Mg, Ca, Fe,Mn, Zn, Cu, and S) and their relationships with phytic acid. The genotypeexpressed the strongest effect on the variability of grain yield and the analyzedgrain constituents. The red-kernel hybrid showed the greatest accumulation ofprotein, oil, phenolics, and essential elements (Ca, Fe, Cu, and S) than a yellowand white hybrid, especially in the biofertilizer treatment. The yellow kernel hadthe highest concentrations of yellow pigment, GSH, phytic phosphorous, Mg,Mn, and Zn (19.61 µg g−1, 1,134 nmol g−1, 2.63 mg g−1, 1,963 µg g−1, 11.7 µg g−1,and 33.9 µg g−1, respectively). The white kernel had a greater starchconcentration (2.5% higher than that in the red hybrid) and the potentialbioavailability of essential metals, particularly under no fertilization. Thissupports the significance of white maize as a staple food in many traditionaldiets across the world. Urea was important for the enhancement of theantioxidant status (with 88.0% reduction capacity for the DPPH radical) andincreased potential Zn bioavailability in the maize kernels (13.3% higher thanthat in the biofertilizer treatment). This study underlines the differences in theyield potential and chemical composition of red, yellow, and white-kernelmaize and their importance as a necessary part of a sustainable human diet.This information can help determine the most appropriate genotype based onthe antioxidants and/or essential elements targeted for kernel improvement.

AB  - Human health is dependent not just on diet, but mainly on quality of agricultural products as a part of diet. If crops were grown on poorly fertile soils, or they are exposed to severe stresses, lesser amount of mineral elements, particularly essential elements, such as zinc, copper, manganese, magnesium, calcium, iron, and even sulphur, will be absorbed and accumulated, resulting in their deficiency in diets and increased incidence of various chronic diseases. Together with naturally low soil fertility, climate change, intensive agriculture is one of the main contributors of soil depletion. Thus, various long-term strategies, which are sustainable for agricultural plants and soils, at the same time, must be developed. It is of particular importance to increase a level of organic matter, as a source of mineral nutrients from the soil. The application through soil, as well as via plant foliage of various complex and organic fertilizers, containing macro- and micro-elements, and many stimulating compounds, enables better absorption and metabolisation of nutrients required for plants and nutrients essential for humans. Besides, bio-fertilizers, containing beneficial microorganisms have an important role in nutrients mobilization in soils, particularly from poorly accessible forms. Many bio fertilizers contain microorganisms that are able to absorb atmospheric nitrogen, thus enriching soil, delivering it to the plants, enabling reduction in amount and costs of nitrogen addition into the soil. Promoting microorganisms are also able to enhance plants ability to absorb water and nutrients by their synergy with roots, resulting in stable and better growth performances of agricultural plants, thus increasing yield and its quality. Some other cropping practices, such as crop rotation, intercropping and use of cover crops, enriches soil with organic matter, reduces losses of nutrients through recycling of harvest residues, therefore increasing soil fertility, as well as quantity and quality of crop yield, at the same time.

AB  - We report on the use of gold nanoparticles (AuNPs) as a colorimetric probe for quercetin (Q). The method is based on the aggregation of the AuNPs that is caused by various quercetin concentrations in the range of 4 mg/L - 15 mg/L and leads to a visually detectable color change. Concentration-dependent aggregation is confirmed by recording of UV-visible absorption spectra. The method provides a useful tool for the rapid visual quercetin determination.

AB  - Two silver–polyaniline/polyvinylpyrrolidone (Ag–PANI/PVP) nanocomposites were prepared using in situ integration of silver nanoparticles (AgNPs) during oxidative aniline polymerization, accelerated by the presence of PVP, which as well minimized the risk of particle agglomeration and macroscopic precipitation. Both nanocomposites have similar silver content (∼44 wt% Ag) but different morphological features of AgNPs (spheres/triangles) and polymers (granular/wrinkling pattern). Several spectroscopic, macroscopic, and analytical techniques, microscopy, and surface analysis methods have been used to analyze their physical and chemical properties. Investigation of their antimicrobial potential and possible application as an effective weapon against indicator microbial strains, E. coli, S. aureus, and C. albicans, has shown inhibition of microbial growth by more than 90%, even at low composite concentrations (5 ppm) and short contact time (4 h). A biosafety assessment of Ag–PANI/PVP that comprised testing the genotoxicity and redox modulating activity was performed using human peripheral blood cells as a model system. The obtained results have shown that the investigated Ag–PANI/PVP exhibited significant prooxidant and cytostatic effects (p < 0.05) with no apparent potential to induce DNA damage. Although precautions should be taken to protect human health, the significant antimicrobial efficiency of Ag–PANI/PVP makes it suitable for further studies and applications in non-medical areas, such as wastewater treatment.

AB  - Cover crops (CC) are an important low-input strategy in sustainable agricultural sys-tems. The impact of different CC (common vetch, field pea, winter oats, fodder kale, common vetch + winter oats and field pea + winter oats), organic mulch, control treatment-fallow, and bio-fertilizer (BF) application, on yield and quality of sweet maize kernel was evaluated. CC biomass was higher in mixtures: field pea + winter oats, and common vetch + winter oats, as well as in fodder kale. Kernel yield and its chemical composition varied significantly by CC, BF, year, and their interaction. Organic mulch enhanced the concentration of sugars and glutathione in maize kernel. BF increased kernel yield, the concentration of sugars, vitamin C, Mg, Fe, Zn, and reduced phytate concentration. The highest Mg and Mn concentration in maize kernel was achieved with fodder kale, Zn concentration with common vetch + winter oats + BF, and Fe concentration with winter oats. The same treatments expressed the highest impact on variability in concentration of the phytate, phenolics, and yellow pigment, thus affecting further bio-availability of essential elements. Results indicate that in a semi-arid climate, under rain-fed conditions, CC such as fodder kale and winter oats + common vetch could enhance sweet maize productivity and kernel quality, serving as an important part of a sustainable cropping system, to facilitate food security.

AB  - Due to the increased use of yttrium in agriculture and industry, there is a growing interest in the impact of yttrium on the environment and human health. Developing novel procedures to detect and quantify species of yttrium represents an important task. In this work, we apply laser desorption/ionization-mass spectrometry (LDI-MS) to detect cluster ions of the solution of yttrium(III) chloride (YCl3) at different pH values. The density functional theory (DFT) calculations were used to reveal the energetically most favored structures of the anions and cations chosen from the LDI-MS results. Examination of the positive and negative mode LDI mass spectra of YCl3 showed the presence of the heterogeneous mononuclear and polynuclear clusters, such as [YCl(OH) (H2O)3]++, [Y2(H2O)]++, [Y4H2(H2O)4]++, and [Y5O4H3]++ (at pH 2 and 5) and [Y2Cl2(H2O)2]−−, [Y2O5(HCl)(OH)]−−, and [Y3OH3(OH)2(H2O)]−− (at pH 2, 5, and 10). The variation in the pH solution of YCl3 slightly affects the LDI mass spectrum of these yttrium clusters. It has only been noticed that the [Y4H2(H2O)4]++ cluster ions were not detected at pH 10. These results can become a guide in the detection of yttrium chloride by LDI-MS in real samples in different fields (ecological, food, and human).

AB  - Silver alloys are generally used in the different fields of industry, including chemical processing, construction, heat exchangers, etc. Although Ag-Cu-Zn-Cd type of alloys, were widely exploited in the second half of the 20th century for their excellent properties, its use is forbidden in the EU due to the high toxicity of cadmium vapors. Ag-Cu-In type of alloy is a good alternative to Ag-Cu-Zn-Cd alloys, with great properties and can be used in various fields of industry. Most common methods for characterization of surface corrosion films of Ag-Cu alloys are: X-ray diffraction (XRD), scanning electron microscopy with energy dispersion spectroscopy (SEM-EDS), Raman spectroscopy and atomic force microscopy (AFM). Our current study focuses on the application of laser desorption ionization mass spectrometry (LDI MS) for determination of corrosion products of Ag-Cu alloy. The aim of this study was to confirm LDI MS as a fast, accurate and reliable method for determination of corrosion products on the surface of Ag-Cu-In alloy.

AB  - This work considers possible uses of fruit-based waste for the production of valuable chemicals and biofuel precursors through recycling by thermochemical conversion. Slow pyrolysis of Goji berry mesocarp (GBM) as sugar-rich feedstock was investigated using simultaneous thermal analysis (STA) measurements in non-isothermal conditions. Results reveal that pyrolysis of GBM represents a promising route to obtain important key platform chemical - 5-hydroxymethylfurfural (5-HMF). It was found that autocatalytic dehydration of fructose (in a presence of Lewis acids) is responsible for production of 5-HMF at a low heating rate (5.0 K/min) with a maximum 5-HMF theoretical yield of 63.20 %. Higher heating rates (10.0 and 15.0 K/min) trigger fructose autogenesis behavior which opens the transferability channel to glucose engagement for 5-HMF theoretical high yield production.

AB  - Nickel−cobalt (Ni−Co) alloy powders were produced galvanostatically by using sulphate electrolytes withvarious ratios of Ni2+/Co2+ (mole ratios). The morphology, phase structure, chemical composition and magneticproperties were examined by scanning electron microscope (SEM), X-ray diffractometer (XRD), atomic emissionspectrometer (AES), and SQUID-based magnetometer, respectively. Morphology of the particles changed fromcauliflower-like and dendritic to coral-like and spongy-like ones with increasing Ni2+/Co2+ ratio from 0.25 to 4.0. XRDanalysis of the Ni−Co powders revealed that the decrease of Ni2+/Co2+ ratios (the increase of Co content) caused achange of structure from face centered cubic (FCC) obtained for the ratios of 4.0, 1.5 and 0.67 to a mixture of FCC andhexagonal closed-packed (HCP) phases for the ratio of 0.25. The increasing content of nickel led to change ofmechanism of electrolysis from irregular (up to ~40 wt.% Ni in the electrolytes) to close to equilibrium (between~40 and 60 wt.% Ni in the electrolytes) and anomalous co-deposition (over 60 wt.% Ni in the electrolytes) type. All ofthe obtained Ni−Co alloy samples behaved as soft magnetic materials while their magnetic parameters showedimmediate composition dependence since both coercivity and saturation magnetization almost linearly increased withincrease of the Co content.

AB  - Surface modifications of metallic biomaterials can in great merit, improve the properties of the hard-tissue implants and in that way contribute to the success of the surgical implantation process. Coating deposition stands out as one of the many surface-modifying techniques that can be used to improve implant surface properties and, in turn, induce successful osseointegration. Deposition of the TiO2 layer on the surface of the metallic implants has a great potential to enhance not only their osseointegration ability but also their biocompatibility and corrosion resistance. In the present study, the possibility of successful deposition of the TiO2 layer on the surface of commercially pure titanium (CP-Ti), as the most commonly used metallic implant material, by spraying the colloidal nanoparticles aqueous solution in the electric discharge plasma at atmospheric pressure was investigated. To characterize the colloidal TiO2 nanoparticle solution, used for the coating deposition process, transmission electron microscopy (TEM) was utilized, while scanning electron microscopy (SEM) and optical profilometry were used to investigate the deposited surface layer morphology and quality. Estimation of the deposited film quality and texture was used to confirm that the arc plasma deposition technique can be successfully used as an advanced and easy-to-apply method for coating the metallic implant material surface with the bioactive TiO2 layer which favors the osseointegration process through the improvement of the implant surface properties. The TiO2 coating was successfully deposited using the arc plasma deposition technique and covered the entire surface of the CP-Ti substrate without any signs of coating cracking or detachment.

AB  - The effect of dextran-coated silver nanoparticles (Ag NPs 12.0 ± 1.9 nm) loading (0−0.42 wt%) on the mechanical, barrier, and antimicrobial properties of thin (50−60 μm) films prepared from cellulose nanofibrils by solvent casting method were studied as eco-friendly and food-preservative packaging materials. The presence of dextran was shown to act not only as a dispersing media for Ag NPs and controlling its release but also as a moisture-resistant sealable additive that, synergetically with reduced oxygen permeability, may preserve the food against bacteria growth. Thus, significantly reduced Oxygen Transmission Rates (from 2.07 to 1.40-0.78 cm3 m−2d−1) and hydrophilicity (from 20.8° to 52.4° for MilliQ water, and from 35-37° to 62-74° for 3 % acetic acid and 0.9 % NaCl simulant solutions), yielding a 99.9 % inhibition of Escherichia coli after five repeated cycles of 24 h exposure to 0.9 % NaCl solution was displayed, supported by a controlled release of Ag+ ions (below the toxicologically harmful threshold, <0.5 mg L-1).

AB  - The efficiency of titanate-nanotubes-based photocatalysts towards hydrogen production was studied in the presence of the sacrificial agent, 2-propanol. The highest hydrogen production rate (~120 lmol h 1 g 1 ) was observed over surface-modified titanate nanotubes by 5-amino salicylic acid decorated with nanometer-sized silver nanoparticles. The X-ray diffraction analysis, transmission electron microscopy, nitrogen adsorption–desorption isotherms, and diffuse reflection spectroscopy were applied to characterize the prepared photocatalytic materials. The better photocatalytic performance of inorganic–organic hybrid materials in comparison to the pristine titanate nanotubes is a consequence of their improved light-harvesting ability due to the formation of interfacial charge transfer (ICT) complex, as well as the presence of metallic silver nanoparticles that suppress the recombination of photo-generated charge carriers. The spin trapping EPR experiments under irradiation of prepared photocatalysts with either UV or visible light were used to monitor the appearance of hydroxyl radicals and superoxide radical anions. The generation of superoxide radical anions under visible light irradiation was detected for hybrid materials, but not for the pristine titanate nanotubes. These results are a consequence of enhanced promotion ofelectrons to the conduction band due to extended absorption in visible spectral range in hybrids and support the higher efficiency of hydrogen generation observed for surface-modified titanate nanotubes by 5-amino salicylic acid decorated with silver nanoparticles.

AB  - Hydrothermal synthesis of Mn2+ doped titanate nanotubes (TNTs), which exhibited room temperature ferromagnetism (RTFM), is reported. Dispersions of 1 and 5 at.% Mn2+ doped anatase TiO2 nanocrystals were used as precursors. Size and shape of Mn2+ doped TNTs and precursor nanocrystals were studied by transmission electron microscopy (TEM). The relatively uniform size distribution of transverse dimension of nanotubes of about 10 nm was observed while their lengths varied up to few hundred nanometers. The X-Ray Diffraction (XRD) analysis and Raman spectroscopy of resultant powder confirmed the hydrogen dititanate (H2Ti2O5 x H2O) crystal phase of Mn2+ doped TNTs with the presence of small amount of sodium titanates. Electron paramagnetic resonance (EPR) experiments were performed to probe the local atomic and electronic structure of Mn in the nanotubes. Room temperature ferromagnetic ordering with saturation magnetic moment (Ms) in the range of 0.6–1.5 μB per Mn atom was observed. © 2019 Elsevier Masson SAS

AB  - Antibacterial and antifungal ability of silver nanoparticles (Ag NPs) supported by functionalized magnetite (Fe 3 O 4 ) with 5-aminosalicylic acid (5-ASA) was tested against Gram-negative bacteria Escherichia coli, Gram-positive bacteria Staphylococcus aureus and yeast Candida albicans. Characterization of materials including transmission electron microscopy, X-ray diffraction analysis, and inductively coupled plasma optic emission spectroscopy technique followed each step during the course of nanocomposite preparation. The synthesized powder consists of 30–50 nm in size silver particles surrounded by clusters of smaller (∼10 nm) Fe 3 O 4 particles. The content of silver in the nanocomposite powder was found to be slightly above 40 wt.–%. Concentration-dependent and time-dependent bacterial reduction measurements in dark indicated that use of Ag NPs leads to the complete reduction of E. coli and S. aureus even at the concentration level of silver as low as 40 μg/mL. However, the negligible antifungal ability of synthesized nanocomposite was found against yeast C. albicans in the entire investigated concentration range (0.1-2.0 mg/mL of the nanocomposite, i. e., 40–800 μg/mL of silver). Complete inactivation of E. coli and S. aureus was achieved in five repeated cycles indicated that synthesized nanocomposite can perform under long-run working conditions. From the technological point of view, magnetic separation is the additional advantage of synthesized nanocomposite for potential use as an antibacterial agent. © 2019 Wiley-VCH Verlag GmbH & Co.
