Synthesis and crystal structure of ABW-type SrFe1.40V0.60O4
Single crystals of SrFe1.40V0.60O4, strontium tetraoxidodi[ferrate(III)/vanadate(III)], have been obtained as a side product in the course of sinter experiments aimed at the synthesis of double perovskites in the system SrO–Fe2O3–V2O5.

Color Point Tuning for (Sr,Ca,Ba) Si2O2N2:Eu2+ for White Light LEDs [PDF]
Color point tuning is an important challenge for improving white light LEDs. In this paper, the possibilities of color tuning with the efficient LED phosphor Sr1−x−y−zCaxBaySi2O2N2:Euz2+ (0 ≤ x, y ≤ 1; 0.005 ≤ z ≤ 0.16) are investigated.

Effect of 2-Substitution on the Rearrangement of 1-Cyclopropylvinyl Cations [PDF]
2-Substitution in 1-cyclopropylvinyl cations produces a steric effect on cation generation and solvent trapping, but an electronic charge-stabilizing effect on cyclopropyl-to-cyclobutyl ...

Thermochemistry of Monocharged Cation Substitution in Ionic Solids
Abstract A rather straightforward synthetic procedure for the production of new materials is the substitution of principal ions in the crystal for one another, and some general principles relating to structure have been developed which guide the material designer as to which substitutions are likely to lead to ...
