Platinum nanoparticles stabilized by imidazolium-based phosphine-decorated Polymer Immobilized Ionic Liquids (PPh2-PIIL) catalyze the hydrolytic evolution of hydrogen from sodium borohydride with remarkable efficiency, under mild conditions. The composition polymer influences efficiency catalyst based on a polyethylene glycol modified imidazolium monomer (PtNP@PPh2-PEGPIILS) more active than it...

Some properties of dissolved organic matter (DOM) and chromophoric dissolved organic matter (CDOM) can be easily measured directly on whole waters, while others require sample concentration and removal of natural salts. To increase CDOM content and eliminate salts, solid phase extraction (SPE) is often employed. Biases following extraction and elution are inevitable, thus raising the question o...

Chemical vapor phase deposition was used to create hydrophobic nanostructured surfaces on glass slides. Subsequently, hydrophilic channels were created by sputtering a metal catalyst the while masking outside. The surface tension gradient between in and outside hydrophobicity formed open-channel system. reduction of para-nitrophenol (PNP) studied these devices. When compared nanostructure-free ...

The dehalogenation of a-haloketones and a-halocarbonyl compounds is an inevitable proce­ dure for the organic synthesis and these reductive dehalogenations have been often effected in organic syntheses. There have been various procedures for the purpose and these are obtained by zinc and acetic acid [1], sodium dithionite [2], titanium(III) chloride [3], organotin hydride [4], sodium hydrogen t...

In the presence of large excesses of borohydride salts, gold monolayer protected-clusters can be grown to larger sizes simply by controlling the amount of reducing agent added to smaller clusters. In addition, gold monolayer clusters can be used as catalysts for reduction reactions by sodium borohydride; results suggest such catalysts have sterically constrained active sites.

Supported nano zero-valent iron is receiving great attention nowadays due to its effectiveness in treating heavy metal pollutants. Therefore, this study aimed investigate the of granitic residual soil-supported (Gr-nZVI) for removal metals Pb2+, Cu2+, Co2+, Cd2+ Ni2+ and Zn2+ mixture solutions under different experimental conditions batch equilibrium tests. In study, Gr-nZVI was successfully sy...
