CdS nanoparticles were successfully synthesized using starch, amylopectin and maltodextrin, as a capping agent. Optical properties of the final products have been investigated by photoluminescence spectroscopy and Raman scattering. The atomic force microscopy gave a particle of an average size of approximately 6 nm. Our research reveals that all prepared sugar–quantum dot aqueous solutions were...

Spontaneous formation of ruthenium nanochains is accomplished in aqueous medium under mild conditions using a seed mediated protocol with cetyl trimethylammonium bromide (CTAB) as the capping agent. They are formed due to the random self-assembly of Ru seeds of ∼3.5 nm size. These 1D nanostructures exhibit better catalytic activity towards the oxidation of CO relative to the ∼3.5 nm seeds and 6...

Fifth generation ethylendiamine-core poly(amidoamine) (PAMAM G5) is presented as an efficient capping agent for the preparation of metal and semiconductor nanoparticles by ps laser ablation in water. In particular, we describe results obtained with the fundamental, second and third harmonic of a ps Nd:YAG laser and the influence of laser wavelength and pulse energy on gold particle production a...

Acanthamoeba capping protein increased the rate of actin polymerization from monomers with and without calcium. In the absence of calcium, capping protein also increased the critical concentration for polymerization. Various models were evaluated for their ability to predict the effect of capping protein on kinetic curves for actin polymerization under conditions where the critical concentratio...

Each actin filament has a pointed and a barbed end, however, filament elongation occurs primarily at the barbed end. Capping proteins, by binding to the barbed end, can terminate this elongation. The rate of capping depends on the concentration of capping protein [1], and thus, if capping terminates elongation, the length of filaments should vary inversely with the concentration of capping prot...

The one-pot synthesis strategy of Au@Pd dendrites nanoparticles (Au@Pd DNPs) was simply synthesized in a high-temperature aqueous solution condition where cetyltrimethylammonium chloride (CTAC) acted as reducing and capping agent at high temperature. DNPs with highly monodisperse were shown yields by the Au:Pd rate. nanostructure optical crystalline properties characterized UV–vis spectroscopy,...

Abstract Three plants extracts of Eucalyptus, Pomegranate and Oolong tea leaves have been used to synthesize iron oxide nanoparticles. The structure particle size the nanoparticles investigated by XRD spectrum. results exhibit polycrystalline nature material with a around (17-19 nm). FESEM analysis showed that using different as reduction capping agent might affect shape such forming round, pol...
