A simple, sensitive, and specific assay for monoacylglycerol hydrolase activity of rat adipose tissue is described. Monoacyl[(3)H]glycerols with different chain lengths (8-18 carbon atoms) and different degrees of unsaturation in mixed micellar solution with different detergents can be used as substrates. The [(3)H]glycerol that is produced is isolated in a one-step liquid-liquid partition proc...

A conductive substrate can provide a simple and straightforward way to induce charge-transfer plasmon modes in Au nanoparticle clusters. For a simple dimer structure, a remarkably narrow charge transfer plasmon, which differs dramatically from the dipolar plasmon mode of the electrically isolated nanostructure, is clearly observed. For a more complex nonamer cluster that supports a strong Fano ...

CoCrFeNiAlx (x = 0 and 1.0) high-entropy alloy coatings were synthesized on Ti6Al4V via laser cladding to improve their corrosion wear resistance under corrosive conditions. Results indicated that the coating (CoCrFeNi) was largely composed of irregular primary ?(Ti) honeycomb-like eutectics + Ti2Ni as matrix, with TiC dendrites reinforcement. When Al introduced into material, grains transforme...

The aim of this paper is to study the effect of substrate on the Cu3N thin films. At first Cu3N thin films are prepared using DC magnetron sputtering system. Then structural properties, surface roughness, and electrical resistance are studied using X-ray diffraction (XRD), the atomic force microscope (AFM) and four-point probe techniques respectively. Finally, the results are investigated and c...

Co-metabolic degradation of monofluorobenzoates was carried out by a mixed soil population in a basal salts medium. The monofluorobenzoates did not support growth of microorganisms but were shown to be subject to ring cleavage as a result of microbial activity. Rate of ring cleavage was increased by use of the co-substrate enrichment technique using glucose as the co-substrate. Results indicate...

Semicarbazide-sensitive amine oxidase (SSAO) is a copper-containing enzyme that catalyzes the oxidative deamination of endogenous and exogenous primary amines. SSAO exists in mammals both as a plasma-soluble and as a membrane-bound form, and its active site is able to come into contact with numerous xenobiotic, amine-containing compounds. The kinetic studies performed in this work showed that c...
