ABSTRACT: Grafted copolymers of chitosan–vinylpyrrolidone, water-soluble at a pH of 6.8–7.5, were obtained. A technique has been developed for obtaining an aggregatively stable system of platinum nanoparticles in copolymer solutions with an average size of ~4 nm. The...
ABSTRACT: Ternary In-Sn-Bi alloys exhibit potentially superior superconducting properties compared to other lead-free solders, making them promising candidates for replacing lead-based solders in superconducting joints. In this work, the microstructure and...
ABSTRACT: In-situ experimental techniques are essential for understanding the deformation evolution of materials by enabling real-time tracking of microstructure changes. This study employs in-situ electron backscatter diffraction (EBSD), high-resolution digital image...
ABSTRACT: The work functions of two polar surfaces of ZnO (wurtzite), i.e., O-(000–1) and Zn-(0001) are determined by photoelectron spectroscopy in ultrahigh vacuum or in the presence of oxygen or water vapor at near-ambient pressures, and by Kelvin probe in air. The...
ABSTRACT: Twisted 2D material heterostructures provide an exciting platform for investigating new fundamental physical phenomena. Many of the most interesting behaviours emerge at small twist angles, where the materials reconstruct to form areas of perfectly stacked...
