A series of luminescent emission-tunable phosphors Ca12Al14O32F2:Tb3+,Eu2+,Eu3+have been synthesized by a high temperature solid-state reaction in a reductive atmosphere.The sample phase was determine
Zeolite Y is widely used in catalysis,adsorption,ion exchange and other fields,which has many unique properties because of its uniform and regular pore structure,enormous surface areas and more surfac
Due to its excellent UV-rays shielding properties,size-controlled ceria nanoparticles were prepared by chemical method.Then the surface of nanoparticles was modified by surfactant and were embedding i
Hydrogen storage alloys La0.83-xSmxMg0.17Ni3.1Co0.3Al0.1(x = 0.0-0.4)were prepared by induction melting followed by annealing treatment in argon atmosphere.
Solid oxide fuel cells are of great interest because they are composed of all-solid components and elevated operating temperatures,providing superior performance such as fuel utilization efficiency,du
In this work,we present a detailed study on the magnetocaloric effect of the first-to-second order magnetic phase transformation of La0.7Ca0.275Ba0.025MnO3 nanocrystals with averaged crystallite size
