The organo-amidocuprate [Cu(2)Li(2)Mes(2)(N(CH(2)Ph)(2))(2)] is solvated by thf to yield the monomeric contact ion pair complex [MesCuN(CH(2)Ph)(2).Li(thf)(3)] in which the Li cation is bound to the amido nitrogen; this behaviour differs significantly from that observed in diorganocuprates which favour solvent separate ion pairs.

Magnesium (Mg) deficiency increases genomic instability and Mg intake has been reported to be inversely associated with a risk of colorectal cancer (CRC). This study was designed to determine whether organo-Mg in drinking water suppresses inflammation-associated colon carcinogenesis in mice. Male Crj: CD-1 mice were initiated with a single i.p. injection of azoxymethane (AOM, 10mg/kg body weigh...

PURPOSE Biofilm formation is a problem for solid and sponge-type scleral buckles. This can lead to complications that require removal of the buckle, and result in vision loss due to related ocular morbidity, primarily infection, or recurrent retinal detachment. We investigate the ability of a covalent organo-selenium coating to inhibit biofilm formation on a scleral buckle. METHODS Sponge and...

The sol gel process is one of the processes used in manufacture thin films on membranes because it can control pore size resulting silica matrix. In addition, another way to build membrane be done by adding catalysts and precursors used. this study, using a combination tetraethyl ortho silicate (TEOS) triethoxy vinyl silane (TEVS) citric acid as catalyst produce matrix with mesoporous so that s...

Introduction. Brominated flame retardants (BFRs) are chemicals that are added to polymers that are used in plastics, rubber, textiles and other materials to prevent fires. Similarly to other organic pollutants, BFRs have persistence and bioaccumulation potential in organisms. Recently, BFRs have become of increasing concern in environmental samples, due to the increase of the concentration of B...

We investigate the electrical behavior of a symmetric liquid crystal (LC) cell: elecrode-silane-LC-silane-electrode. The silane (chlorodimethyloctadecyl-silane) layer induces a homeotropic orientation of the nematic liquid crystal (NLC) molecules. The wettability technique is used to detect the change of the surface energy of the electrode upon cleaning and silane layer deposition. We report on...

The immobilization of Candida antarctica lipase B (CALB) was performed by physical adsorption on both neat and organo-modified forms of sepiolite and montmorillonite. The influence of different parameters, e.g., solvent, enzyme loading, cross-linking, and type of clay support, on immobilization efficiency and catalyst hydrolytic activity has been investigated. The highest hydrolytic activities ...

Effects of modifying oil palm mesocarp fibers (OPMF) by methacrylate silane on polylactic acid (PLA)/ polycaprolactone (PCL)/clay/OPMF hybrid composites were investigated. The composites were prepared by a melt blending technique and characterized by dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM). The silane-treated OPMF hybrid composites showed better tensile strength...
