Abstract
Si/SiO_x composite anodes were prepared using a facile solution reaction-based method. Their initial capacity was significantly improved to 1.3 times that of SiO_x by incorporating 3 wt% silicon nanoparticles into the SiO_x. The capacity retention of the Si/SiO_x anodes after 50 charge-discharge cycles was significantly enhanced, to 99%, compared with..... More

Abstract
Ti-doped In₂O₃ (TIO) thin films were deposited on glass substrates by RF magnetron sputtering. The films were then annealed at 100, 200 or 300 °C for 30 min to investigate the effects of the annealing temperature on the films’ structural, electrical and optical properties. The films annealed at 200 °C..... More

Abstract
During the selective extraction of Pd(II) by LIX 63 from 6 M HCl solutions containing platinum group metals, an oxidation-reduction reaction occurs between the LIX 63 and Ir(IV). Since the reduced Ir(III) cannot be extracted by solvating and amine extractants, the oxidation-reduction reaction has a significant effect on the separation..... More

Abstract
In this work, both experimental and numerical studies were conducted to investigate the densification behavior of stainless steel 316L (STS 316L) powders during hot isostatic pressing (HIP), and to characterize the mechanical properties of HIPed specimens. The HIP experiments were conducted with gas atomized STS 316L powders with spherical particle..... More

Corrosion & Surface Treatment

Abstract
Pure Mg, Mg-5wt%Ca, and Mg-5wt%Ca-1wt%Zn alloys were cast, and their high-temperature oxidation behavior was investigated to determine the roles of Ca and Zn in oxidation. Ca and Zn additions refined the microstructure by formation of Mg₂Ca and Ca₂Mg₆Zn₃, respectively, at grain boundaries. Ca increased the oxidation resistance by forming a..... More

Material Analysis & Characterization

Abstract
In order to strengthen the structure of the glass and ultimately improve its water resistance, P₂O₅–ZnO–Bi₂O₃ was doped with Fe₂O₃, which generated Fe ions in the phosphate-based glass. These ions constitute (P₂O₇)⁻⁴ groups within the glass network. Structural analysis using Fourier transfer infrared spectroscopy indicated that P-O-P and Bi-O-P bonds..... More
