In this study, microparticles of bionanomaterials were obtained by polyvinylpyrrolidone, montmoril-lonite, and zinc oxide bionanosystems produced through solution intercalation technique combined with a spray-drying process, aiming for possible application as drug delivery systems. The final microparticles obtained were evaluated in terms of their production yield, which varies between 39.2% and 56.9%. Thermal analysis showed no major changes in Tg of the nanocomposites, compared to the pure PVP polymer. Scanning electron microscopy analysis revealed a pseudo-spherical shape and confirmed the micrometric size of the microparticles. Transmission electron microscopy analysis corroborated the embedding of montmorillonite and ZnO within the polymer phase. Nuclear magnetic resonance and X-rays diffraction were used to study the nanoparticles dispersion, indicating a predominant intercalated morphology. This study suggests that the applied methodology is suitable for the high yields synthesis of nanocomposites PVP based microparticles with uniform size and shape, which can be promising for the production of a new drug delivery system.A facile and peculiar synthesis strategy is designed for the fabrication of transparent superhydrophobic surfaces on simple glass substrate. The synthesis methodology comprises of two steps of hydrothermal treatment of cleaned glass substrate with ultrapure water as a solvent followed by coating of 1H, 1H, 2H, 2H-perflourooctyltriethoxysilane (POTS) also by hydrothermal treatment in hydrothermal reactor. The hydrothermal treatment of glass substrate lead to the nanostructured surface morphology consisting of nanofibers and a blend of nanofibers/nanoflakes. Aforesaid nanostructured surface morphology upon hydrophobic coating resulted in superhydrophobic properties, increasing the water contact angle (WCA) from 92.0° to as high as 145.3°. Moreover, the developed synthesis approach also resulted in the optical transparent superhydrophobic glass substrate thus offering an attractive methodology to employ for self-cleaning applications.A gold plating technique with wet chemical solution is widely used to make different metallic colors for various industrial applications. However, it results in environmental pollution due to the generation of contaminated water, and it is also an expensive process. As an alternative approach, it is often desirable to use the Physical Vapor Deposition coating method that does not generate such pollution, and to use cheaper material to imitate gold colors. In this letter, target materials consisting of Ti-Zr alloy are employed to realize tens of nanometers thickness metallic thin film that can produce a metallic color that is close to that of natural gold. TiZrN thin films with a thickness ranging (2,000 to 4,000) nm are formed on a substrate using Arc Ion Plating. The results showed that the thin films exhibited an adhesion force of 50 N or more and a hardness of 1,500 Hv or more under a -100 V bias condition, and various gold colors could be realized by changing the ratio of Ti and Zr element of the alloy target.Tungsten oxide (WO₃) is semiconductor material which can be used for various applications. Especially, one-dimensional (1-D) nanostructured WO₃ shows the high photoelectrochemical (PEC) performance due to high surface area and short transport route of electron-hole pair. The flame vapor deposition (FVD) process is an efficient and economical method for preparation of the 1-D nanos-tructured WO₃ thin film. Molybdenum doping is a well-known method to improve the PEC performance of WO₃ by reducing band gap and increasing electrical property. In this study, we prepared the 1-D WO₃ nanostructures doped with Mo by FVD single step process. We confirmed that Mo was successfully doped on WO₃ without changing significantly the original nanostructure, crystal structure and chemical bonding state of WO₃ thin film. As a result of PEC measurement, the pho-tocurrent densities of WO₃ thin film with Mo doping were higher by about 1.4 to 2 times (for applied voltage above 0.7 V vs. SCE) than those without Mo doping.In this study, nanotube morphology changes of Ti-xTa-Ag-Pt alloys with Ta content for biomaterials were researched using various experimental instruments. Ti-xTa-Ag-Pt alloys were manufactured in an Ar atmosphere using a vacuum arc-melting furnace with Ta contents of 10 and 50, and then heat-treated at 1100 °C for 1 hr. Nanotube formation of Ti-xTa-Ag-Pt (x = 10, 50 wt%) alloys were performed using a DC power of 30 V in 1.0 M H₃PO₄ + 0.8 wt% NaF electrolyte solution. Surface characteristics were investigated using an optical microscope, X-ray diffractometer, field-emission scanning electron microscope, energy-dispersive X-ray spectroscopy, and Image analyzer (Image J). Ti-10Ta-Ag-Pt alloy had a needle-like structures, and Ti-Ti-50Ta-Ag-Pt showed the mixed structure (equiaxed and needle-like structures). As the Ta content increased, the α-phase decreased and the β-phase increased. https://www.selleckchem.com/products/lurbinectedin.html The highly ordered nanotubes were formed on the β-phase, whereas disordered nanotubes were formed on needle-like structure of α-phase in Ti-10Ta-Ag-Pt alloy. As the Ta content increases, large and small nanotube diameters became smaller in size. Anatase and rutile phases were formed on the alloy surface. Ta, Ag, and Pt elements were uniformly distributed over the entire surface and at the edge or inside of the nanotube.This study investigated the effects of heat treatment on changes in the nanostructure of amorphous silicon oxycarbide thin films. Hydrogenated amorphous silicon oxycarbide (a-Si0.6C0.3O0.1H) thin films were prepared via plasma-enhanced chemical vapor deposition. The films were subjected to post-deposition heat treatments via microwave-assisted heating, which resulted in the formation of nanocrystals of SiC and Si in the a-Si0.6C0.3O0.1H matrix at temperatures as low as ~800 °C. The crystallization activation energies of SiC and Si were determined to be 1.32 and 1.04 eV, respectively lower than those obtained when the sample was heat-treated via conventional heating (CH). Microwaves can be used to fabricate nanocrystals at a temperature approximately ~300 °C lower than that required for CH. The optical and nanostructural evolutions after post-deposition heat treatments were examined using photoluminescence (PL) and X-ray diffraction. The position of the PL peaks of the nanocrystals varied from ~425 to ~510 nm as the annealing temperature was increased from 800 to 1000 °C.
