Porous Cu(2)O nanospheres with controllable structures were successfully synthesized by using ascorbic acid as the reducing agent and beta-cyclodextrin (beta-CD) as the capping agent via a sonochemical route, which was proved to be a green and convenient method for the controlled synthesis of porous Cu(2)O nanospheres. The crystal phase of the product was determined by the concentration of asco...

Functionalizable monotelechelic polymers are useful materials for chemical biology and materials science. We report here the synthesis of a capping agent that can be used to terminate polymers prepared by ring-opening metathesis polymerization of norbornenes bearing an activated ester. The terminating agent is a cis-butene derivative bearing a Teoc (2-trimethylsilylethyl carbamate) protected pr...

A method is described for the entrapment of proteins in hydrazide-activated supports using oxidized glycogen as a capping agent. This approach is demonstrated using human serum albumin (HSA) as a model binding agent. After optimization of this method, a protein content of 43 (+/-1)mg of HSA/g support was obtained for porous silica. The entrapped HSA supports could retain a low-mass drug (S-warf...

Silver nanoparticles were obtained via totally green synthesis from silver nitrate using glucose as reducing agent and sucralose as capping agent. Physico-chemical characterization of AgNPs was performed by UV-Visible absorption and transmission electron microscopy (TEM) in order to correlate biological/toxicological responses with AgNPs features. A detailed study of silver nanoparticles (AgNPs...

in the present work, bi2s3 nanostructures have been synthesized with the aid of thioglycollic acid (tga) a solvent, capping agent, and sulfide source in the presence of ultrasonic method. the as-synthesized products were characterized by x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (eds), scanning electron microscope (sem), and photoluminescence (pl) spectroscopy. the band gap ...

cdse nanostructures were synthesized by using green chemical route as starch was used as capping agent. xrd, hr-tem, sead, uv and pl studies were made for structural and optical properties of the prepared sample. film morphology and the thickness measurement of n-cdse were carried out with afm analysis. i-v characteristics curve of this junction confirmed the formation of schottky contact betwe...
