Fe3O4 nanoparticles were synthesized in the presence of pepper extract as a capping agent via a hydrothermal method. Then palladium nanoparticles and Fe3O4-Pd nanocomposites were synthesized with the aid of pepper extract as a reducing agent. Vibrating Sample magnetometer illustrated that Fe3O4 nanoparticles have super paramagnetic behaviour. The photo catalytic behaviour of Fe3O4-Pd nanocompos...

ZnS nanoparticles of different size have been synthesized using a colloidal particles method. ZnS nanoparticles prepared with capping agent (mercaptoethanol) then were characterized using X-ray diffraction (XRD) and UV-Vis spectroscopy. The particle size of the nanoparticles calculated from the XRD patterns has been found in the range 1.85-2.44nm. Absorption spectra have been obtained using UV-...

Oleic acid capped monodisperse SnO(2) quantum dots (QDs) of size 2.7 nm were synthesized by thermal decomposition and oxidation of Sn(II)(oleate) complex in high boiling nonpolar solvent octadecene using oleic acid as a capping agent and N-methylmorpholine N-oxide as an oxidizing agent. FTIR, DSC and TGA were employed to understand the growth of the oleic acid capped SnO(2) QDs through the deco...

introduction: this study was carried out to investigate calcific tissue formation against mineral trioxide aggregate (mta) after pulp capping. materials and methods: the pulps of six teeth from four dogs were exposed and capped with mta. after extraction each tooth was sectioned into halves. each half was then further sectioned in the mesiodistal or buccolingual direction. calcified tissue of t...

We investigated the one-step synthesis of CdS nanoparticles via green synthesis that used aqueous extract of watermelon rind as a capping and stabilizing agent. Preliminary phytochemical analysis depicted the presence of carbohydrates which can act as capping and stabilizing agents. Synthesized CdS nanoparticles were characterized using UV-visible, Fourier transform infrared spectroscopy, X-ray...

OBJECTIVE To evaluate the success rate of a calcium hydroxide-based direct capping agent in permanent teeth. METHOD AND MATERIALS A total of 1,075 permanent teeth were treated in this study. All patients received direct pulp capping with a calcium hydroxide-based agent. Inclusion criteria were teeth with healthy pulps, pulps with signs of reversible pulpitis, and a pulp chamber roof opening s...

A new gated nanodevice design able to control cargo delivery using glucose as a trigger and cyclodextrin-modified glucose oxidase as a capping agent is reported.
