The Greeks first used diatomite over 2,000 years ago in pottery and brick.In this work we determine the structural and thermal properties of SiO2 and Al2O3 in the diatomite using

In the case of our compound (K1.65V1.78W0.22O2(AsO4)2), the structure shows an irregular MO6octahedra (M=V+W) with two abnormal short bonds M—O (1.774 (7) Å) and(1.824 (8)

The scanning electronic microscopy reveals that The surface morphology of all the compositions showed that the grain size decrease from about 2- 4 μm to about 1-2μm

It was found that the structural deformation of the intermediate phase, as compared with the high temperature structure, is similar to that of the ferroelastic phase

In our periodic TiO 2 /TiO/Ti multilayers, the point defects are mainly oxygen 337. vacancies and titanium interstitials in the metallic sub-layer

Consequently, the approximately nine electrons contributed by the five Ag and four Tl atoms are distributed uniformly over the Mo 6 and the two Mo 9 clusters contained in the unit

Synthesis, crystal structure, and electrical and magnetic properties of BaMo6Te6: A novel reduced molybdenum telluride containing infinite chains of trans-face shared Mo6
