One of the most commonly used printing technique today is lithography. The printing plate, which is composed of printing (accept printing ink) and nonprinting (must not accept printing ink) areas is highly important factor for all printing processes. Selective ink adsorption on printing plates is usually achieved by g…

The oxygen migration in the apatite-type lanthanum silicate with the cation substitution

Ting Liao、Taizo Sasaki、Ziqi Sun2013-01-01Research Online (University of Wollongong)

A theoretical model is proposed to determine the effects of Si substitution with Al on the oxygen diffusion in apatite-type lanthanum silicates based on density-functional theory (DFT) calculations for La10(SiO4)4(AlO4)2O2. Substitution changes the stable configuration for excess oxygen from the split interstitial to…
