Visible cathodoluminescence from mechanically milled germanium

Analysis of Mechanically Milled Exchange Coupled Nanocomposite Permanent Magnets

Nanocomposite permanent magnets have recently evoked wide interest because of their interesting properties. They usually consist of a hard magnetic phase having superior coercivities and a soft magnetic phase having improved values of magnetization and when they are coupled together, we get a permanent magnet with enhanced values of both the parameters and thus can be put to a lot of applicatio...

Structural and magnetic properties of mechanically milled SmCo5:C

Coexistence of Ferromagnetic and Glassy States in Mechanically Milled GdAl2

Measurements of DC susceptibility, AC susceptibility, and AC susceptibility with an applied DC bias field were performed on mechanically milled GdAl2. A paramagnetic phase exists above a temperature T ≈ 140 K. However, there are significant deviations from the Curie-Weiss Law in this temperature regime, suggesting multiple magnetic components. Fits to the high temperature data show that two Cur...

Investigation of oxidation behavior and Thermal spray of mechanically milled CoNiCrAlY–YSZ powders

In this study, the effects of mechanical milling and YSZ reinforcing on oxidation behavior of CoNiCrAlY coatings were investigated. Various amounts of YSZ particles (0%, 5%, 10% and 15 wt.%) were mixed with commercial CoNiCrAlY powder and milled for 24 hrs. Then, the mechanically milled and commercial powders were deposited on Inconel 617 substrate using High Velocity Oxygen-Fuel (HVOF) process...

Mesoporous zinc germanium oxynitride for CO2 photoreduction under visible light.

Mesoporous zinc germanium oxynitride was synthesized by a template-free method at high temperature. Through optimizing redox potentials as well as improving crystallinity, this material showed enhanced activity in CO(2) photoreduction.
