Optical spectroscopy study on CeTe$_3$: evidence for multiple charge-density-wave orders

, 2010
We performed optical spectroscopy measurement on single crystal of CeTe$_3$, a rare-earth element tri-telluride charge density wave (CDW) compound. The optical spectra are found to display very strong temperature dependence.

KOH-Assisted Molten Salt Route to High-Performance LiNi_0.5Mn_1.5O₄ Cathode Materials

Molecules
A simple and cost-effective route based on a KOH-assisted molten salt method is designed here to synthesize LiNi0.5Mn1.5O4 spinel. Pure-phase LiNi0.5Mn1.5O4 can be successfully prepared using chlorides as raw materials and adding KOH at 700 °C.

Improved surface acidity of CeO2/TiO2 catalyst by Cu doping to enhance the SCR catalytic activity

Scientific Reports
The catalyst is based on CeO2 cannot be widely used in SCR reaction because of its poor NH3 adsorption performance. In this study, Cu-doped CeTi catalyst was designed. The results show that the CeTiCu0.3 has a wide active temperature window of 200–450 °C
