Impact of selenization with NaCl treatment on the physical properties and solar cell performance of crack-free Cu(In,Ga)Se microcrystal absorbers.

In this study, we developed an ink using hexanethiol and Cu(In,Ga)Se microcrystals (CIGSe MCs) to make thin films doctor blade coating. Besides, crack-free thin films were obtained by optimizing CIGSe MC powder concentration and annealing temperature. Subsequently, single-step selenization was performed with and without sodium chloride (NaCl) surface treatment by carefully tuning the temperature.

The visible-light-driven photocatalytic reduction of Cr using BiVO: assessing the effect of Au deposition and the reaction parameters.

In this work, fern-leaf-like BiVO was used to photocatalytically reduce Cr in water. Nanosized BiVO displayed bandgap energy and specific surface area of 2.49 eV and 5.

ZrO/ZnO/TiO Nanocomposite Coatings on Stainless Steel for Improved Corrosion Resistance, Biocompatibility, and Antimicrobial Activity.

The ultrathin nanocomposite coatings made of zirconium oxide (ZrO), zinc oxide (ZnO), and titanium oxide (TiO) on stainless steel (SS) were prepared by the radio frequency sputtering method, and the effects of the nanocomposite coating on corrosion protection and antibacterial activities of nanocomposite coated SS were investigated. Scanning electron microscopy was conducted to observe surface morphology of nanocomposite coatings with distinct distribution of grains with the formation on SS substrate. From the electrochemical impedance spectroscopy results, ZrO/ZnO/TiO nanocomposite coating showed excellent corrosion protection performance at 37 °C during immersion in simulated body fluid and saliva solution for 12 and 4 weeks, respectively.
