The piezoelectric phenomena uses in various helpful applications, such as printing of inkjet, the detection sound and production high voltage electricity different electronic devices. In present research, polyethylene oxide (PEO), poly(methyl methacrylate) (PMMA) poly(N-vinyl pyrrolidone) (PVP) were separately dissolved deionized water. These polymers mixed with ratio 0.6:0.2:0.2 wt%, respectiv...

Salt metathesis reactions of Cp(2)(NR(2))ZrX (X = Cl, I, OTf) and lithium hydrosilazides ultimately afford hydride products Cp(2)(NR(2))ZrH that suggest unusual β-hydrogen elimination processes. A likely intermediate in one of these reactions, Cp(2)Zr[N(SiHMe(2))t-Bu][N(SiHMe(2))(2)], is isolated under controlled synthetic conditions. Addition of alkali metal salts to this zirconium hydrosilazi...

Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs). Herein we report the mol-ecular structure of tris-(di-methyl-amido)-bis-(di-methyl-amine)-zirconium(IV) iodide, [Zr(C2H6N)3(C2H7N)2]I. The bond lengths and bond angles are consistent with a slightly...

A sensitive and reproducible method for the direct spectrophotometric determination of zirconium is reported. The method is based on zirconium forms a stable bluish violet colour complex with Chrome Azurol S (CAS) which has maximum absorption at 598 nm at pH 4.2. The complex obeys Beer’s law in the concentration range of 1-7 μg/mL. Detection limit, molar absorptivity and Sandell’s sensitivity w...
