This study presents the magnesiothermic reduction of silica into silicon. This reduction process occurs at a lower reaction temperature than its carbothermal counterpart. Furthermore, silica was extracted from sugarcane bagasse ash via a thermo-chemical treatment method using, for the first time, L-cysteine chloride monohydrate and used as a precursor in the production of silicon using magnesiothermic reduction. The as-synthesized nanocrystalline silicon’s physicochemical properties were investigated using XRD, Raman, FTIR, BET, and SEM. A peak at 2 of 28.2 with a crystallite size of 32 nm was discovered using X-ray diffraction spectroscopy. The pronounced peak around 518 cm−1 was observed from the Raman spectrum, characteristic of crystalline silicon. The FTIR analysis showed two sharp peaks at 446 cm−1 and 1056 cm−1, indicative of the Si-O rocking mode and Si-O-Si stretching mode functional groups present. N2 physisorption at 77 K reveals that the surface area, pore volume, and pore diameter of the as-synthesized silicon were 73 m2/g, 0.23 cm3/g, and 12 nm, respectively. In this study, we were able to produce silicon from silica extracted from SCBA using the magnesiothermic reduction method in a tube furnace, which has potential for thin-film solar cells.

The work studies the influence of the silver dopant (<0.5 at.%) on the structure and mechanical properties of porous TiNi alloys obtained by self-propagating high-temperature synthesis. These alloys are of high scientific and practical interest in medicine. The presence of silver in the TiNi alloy will ensure improved cytocompatibility and antibacterial properties. The TiNi porous alloys with 0.2 and 0.5 at.% Ag nanoparticles have multiphase composition. Quantitative X-ray diffraction analysis of the obtained alloys showed that an increase in the silver content is accompanied by a quantitative decrease in the austenite phase TiNi(B2) and an increase in the martensite phase TiNi(B19’), as well as in secondary phases Ti2Ni, Ti4Ni2O. Evenly distributed silver nanoparticles up to 10 nm were found in the surface layer by transmission electron microscopy. The results of the scanning electron microscopy showed that inclusions containing silver are located mainly in the zones of Ti2Ni peritectic crystallization. The mechanical characteristics were studied by means of compression tests and it was found that with an increase in the silver dopant, the elastic modulus and elastic limit decrease, but the maximum deformation to fracture increases significantly. It was found that with an increase in the volume fraction of silver, the plastic properties of the alloy increase. No dependency of the tensile strength on the amount of silver was found.

Zinc oxide nanoparticles (ZnO NPs) are widely used in biomedical applications due to their antimicrobial and antioxidant properties. The objective of the present study was to determine the antifungal activity of ZnO NPs against the yeast Saccharomyces cerevisiae. The turbidity test results showed a significant (p < 0.05) dose-dependent growth inhibitory effect of ZnO NPs on S. cerevisiae as the growth inhibition increased from 7.04 ± 0.64 to 70.30 ± 3.19% as the concentration of ZnO NPs increased from 5 to 150 μg/mL. The scanning microscopy images evidenced the morphological alterations such as regional invagination, pitting, cracks, wrinkles, and cell wall rupture in the yeast cells treated with ZnO NPs. In addition, the FTIR spectrum revealed the possible involvement of hydroxyl, alkene, amides, carbonyl, and phosphate groups from polysaccharides, polypeptides, phospholipids, and ergosterol of the yeast cells wall for binding of ZnO NPs on the cell surface. The present study has demonstrated the antifungal activity of ZnO NPs on S. cerevisiae through growth inhibition and the morphological damages resulting from the treatment of ZnO NPs. Full article

In the last two decades, fluorescent carbon quantum dots (CQDs) have attracted intense interest as a new fluorescent nanomaterial with unique properties. This material offers significant advantages compared with conventional dyes and inorganic QD systems, and is used extensively in many different fields, especially in bioimaging and sensor applications. Despite all the positive values they offer, the production of CQD systems with excitation wavelength-dependent nature and high quantum yield (QY) is still a scientific challenge. In this study, we proposed the fabrication of CQD through a facile and easy-to-tune hydrothermal method using cheap and biocompatible precursors such as urea and lactic acid. The effect of experimental parameters including synthesis time, temperature, and mass ratio of the precursors, were determined to obtain the highest QY (48%). The as-prepared nitrogen-doped (N-doped) CQDs exhibited robust stability in the dark and in a wide range of pH values with excitation wavelength-dependent properties. Additionally, CQDs showed remarkable sensitivity and selectivity in the sensing of Fe3+ in blood plasma with a linear correlation in the range of 0–1000 μM, indicating the high potential of CQDs in practical applications. Lastly, cytotoxicity and antibacterial activity tests demonstrated the low toxicity and high biocompatibility of proposed CQDs. Considering the facile and efficient synthetic method, easy-to-tune optical properties, excitation-dependent nature, high fluorescence activity, and low cytotoxicity, we strongly anticipate that N-doped CQDs could provide unique advantages in various biomedical applications including diagnosis, bioimaging, and biosensors.

Nano-sized manganese oxide and cadmium oxide were formed quantitatively via chemical routes, using calcination from an aqueous solution containing metal chloride as a precursor, to create polyvinyl alcohol and para-aminobenzoic acid complexes with the following formulae: [Mn (PVA)(P-ABA) (H2O)3] H2O and [Cd (PVA)(P-ABA) (H2O)3]. The synthesized complexes and metal oxide nanoparticles were characterized using elemental analysis, thermal analyses (TGA and DTA), FT-IR spectroscopy, XRD analysis, UV-vis spectra, and SEM and TEM electron microscopes. The kinetic and thermodynamic parameters (∆H*, ∆G* and ∆S*) for the Mn(II) and Cd(II) coordination compounds were calculated. The antimicrobial properties of the samples were assessed using five bacterial strains and three fungal strains. Three strains of (G+) bacteria, two strains of (G−) bacteria, one stain of yeast-like fungi, and two molds were used in this study. Full article
