The Ca(B'Nb-1/2(1/2))O-3 [B' = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Y, Er, Yb, and In] complex perovskites have been prepared by conventional solid-state ceramic route. The structure and microstructure of the ceramics have ...

New tris(3-phenyl-4-aroyl-5-isoxazolonate)terbium(III) complexes have been synthesized and characterized by various spectroscopic techniques. Due to an efficient energy transfer from the heterocyclic beta-cliketonate ligand ...

The formation characteristics of CuAl2O4 from sol-gel boehmite doped with Cu2+, ion and also the effect of dopants like Cu2+, Ti4+ and Cc(4+) on calcination and concentration dependent structural evolution of alpha-Al2O3 ...

Silica-gelatin nano-hybrid composites are reported where the synthesis has been done through hydrolysis of tetraethoxysilane (TEOS) in presence of gelatin solution. Chemical interaction between silica and gelatin, gelation ...

A1-5 vol% graphite particulate composite was subjected to equal channel angular pressing (ECAP) at room temperature up to four passes. A significant grain refinement, down to the submicron level of similar to 300 nm was ...

The phytochemical compounds oryzanols, tocopherols, tocotrienols and ferulic acid were identified in the crude methanolic extracts (CME) of defatted rice bran (DRB) by HPLC. Enrichment of antioxidants in CME was achieved ...

Aims: To evaluate the biocontrol efficacy of culture filtrate containing chitinase from Trichoderma harzianum against Heliothis. Methods and Results: T. harzianum was cultured by submerged fermentation using colloidal ...

The synthesis of novel polycyclic amides has been achieved through the reaction of bishalomethyl pentacyclo[5.4.0.0(2.6).0(3.10).0(5.9)]undecane diones with acyclic and cyclic secondary amines in the presence of an ionic ...

An efficient synthesis of [1,3]oxazino[2,3-a]quinoline derivatives via a three-component reaction of quinoline, DMAD and carbonyl compounds is described.

The presence of discrete reinforcement particles in the matrix of the discontinuously reinforced metal matrix composites considerably alters the matrix microstructure and hence the precipitation hardening kinetics.Therefore ...
