Single crystals of europium(III) scandate(III), with ideal formula EuScO(3), were grown from the melt using the micro-pulling-down method. The title compound crystallizes in an ortho-rhom-bic distorted perovskite-type structure, where Eu occupies the eightfold coordinated A sites (site symmetry m) and Sc resides on the centres of corner-sharing [ScO(6)] octa-hedra (B sites with site symmetry )....

An artificial joint (prosthesis) helps reduce pain and improve function. Also called total hip arthroplasty, replacement surgery might be an option if interferes with daily activities nonsurgical treatments haven't helped or are no longer effective. We review the different materials, constructions, surfaces used in development of femoral stems, order to solve avoid various problems associated t...

Density-functional theory (DFT) for electrons at finite temperature is increasingly important in condensed matter and chemistry. The exact conditions that have proven crucial in constraining and constructing accurate approximations for ground-state DFT are generalized to finite temperature, including the adiabatic connection formula. We discuss consequences for functional construction.

Using the formula periodic table for benzenoids (Table PAH6 = Table 1 in [4]) and the excised internal structure concept, several new strictly peri-condensed series possessing an identical number of isomers have been identified [5]. Strictly peri-condensed benzenoids have the property that the graph spanned by their internal carbon vertices (i.e., their excised internal structure) is connected....
