Reaction of K[HC(C(Me)NAr')(2)] (Ar' = 2,6-C(6)H(3)(i)Pr(2)) with Mg(BH(4))(2) afforded the pseudo four-coordinate tetrahydroborate complex Mg{HC(C(Me)NAr')(2)}(BH(4))(THF) (1). The corresponding reaction of Ca(BH(4))(2)(THF)(2) or Sr(BH(4))(2)(THF)(2) gave the pseudo five-coordinate analogues M{HC(C(Me)NAr')(2)}(BH(4))(THF)(2) (M = Ca (2) or Sr (3)). All three compounds 1-3 have been structura...

The potential use of wastewater sludge as a biosorbent for the removal various metals and metalloids from aqueous solutions was investigated. immobilized in rod shape with chitosan to improve sorption capacity solid–liquid separation ability. An optimal condition production rod-shaped chitosan-immobilized (RCS) determined by considering As(V) efficiency. contents RCS thickness were 6.0%, 4.0%, ...

The perovskite compounds ABO3 are one of the most common oxide structures and thus have been extensively studied. Indeed, they present a very large panel of interesting physical properties (ferroelectricity, piezoelectricity, superconductivity ...) [1]. Some of them also present magnetic properties and are thus potentially multiferroic. Multiferroic materials are widely investigated nowadays, b...
