Quaternary pyrochlore-type solid solutions, CaGdZrNb1−xTaxO7 (x = 0,0.2, 0.4, 0.6, 0.8, 1), were prepared by a high-temperature ceramic route. The pyrochlore phases of the compounds were confirmed by powder X-ray ...

Inhibitory potential of sea buckthorn (Hippophae rhamnoides L) seed proanthocyanidins against oxidative stress and xanthine oxidase activity was evaluated. Composition of antioxidant proanthocyanidins was profiled by ...

The presence of trace level (<1 ppm) carbonate ion in the interlayer space of MgAl-LDH has been estimated by ion chromatography technique using a novel inverse chemical suppression method using 0.5 mM H2SO4 as mobile phase ...

BaNb(2-x)TaxP2O11 (x = 0, 0.5, 1, 1.5 and 2) ceramics were prepared by the conventional solid state ceramic route. The relative permittivity (er) of the ceramics decreased from 25.3 for x = 0 to 12.9 for x = 2. BaTa2P2O11 ...

Enhancement of Raman signals of pyrene due to the enhanced electric fields on the surface of silver nanoparticles has been investigated by controlling the thickness of the silica shell.Dimeric nanostructures having ...

Mercuric triflate or mercury(II) trifluoromethane sulfonate,Hg(CF3SO3)2 is a white powdery solid, hygroscopic in nature and soluble in water. It belongs to the chemical family of metal triflate compounds and is toxic upon ...

Methods are described for the selective diametrical functionalization of calix[4]arenes at the upper rim by formamide and isocyanide functional groups. The adaptation of Ugi-4-CR to calix[4]arenes leading to a-acylaminocarboxamide ...

Production of bioethanol from lignocellulosic biomass is very challenging due to the heterogenous nature of the feedstock. An efficient pretreatment is necessary for maximizing the enzymatic hydrolysis efficiency and this ...

Substituent effects on cation−π interactions have been quantified using a variety of Φ−X···M+ complexes where Φ,X, and M+ are the π-system, substituent, and cation, respectively.The cation−π interaction energy, EM+, showed ...
