The present study focuses on the exploration of a synthetic procedure for preparation green silver nanoparticles. Using lactose as reducing agent, reaction mixture containing precursor was exposed to ultrasonic irradiation at ambient temperature and conditions. To optimize synthesis, pH levels concentration were varied. acidic level, no nanoparticles produced since there color change observed a...

Green fabrication is an environmentally friendly and innovative method, attractive research field for the production of magnesium oxide nanoparticles (MgO NPs) in clinical environmental applications. In this study, a viable green synthetic approach has been carried out to produce MgO NPs by using leaf aqueous extract Piper nigrum as capping agent. The formation physicochemical properties were c...

A nontoxic, simple, inexpensive, and reproducible strategy, which meets the standard of green chemistry, is introduced for the synthesis of copper nanocrystals (Cu NCs) with olive oil as both reducing agent and capping agent. By changing the reaction parameters, the shape, size and surface structure of the Cu NCs can be well controlled. The obtained Cu nanocubes show excellent catalytic propert...

in this investigation, cuins2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. the cucl, incl3 along with (sc (nh2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (ch(ch2)17nh2) and oleic acid (ch(ch2)16cooh) as a coordination solvent and capping agent, respectively. the size, distribution and shape were...

CdS nanoparticles are II-VI group semiconductor in nature with suitable band gap for photoluminescence and photo-catalyst applications. CdS nanostructures were synthesized via a facile precipitation method in the presence of green capping agents such as starch, glucose, gelatin, salicylic acid in the green solvent of water. The influence of concentration, surfactant, precipitating agent on the ...

Nano-crystalline ZnO particles were synthesized using alcoholic solutions of zinc acetate dihydrate through a colloidal process. Five types of capping agents: 3-aminopropyl trimethoxysilane (Am), tetraethyl orthosilicate (TEOS), mercaptosuccinic acid (Ms), 3-mercaptopropyl trimethoxysilane (Mp) and polyvinylpyrrolidone (Pv) were added at the first ZnO precipitation time (first PPT) to limit the...

This paper provides direct evidence to support the role of a capping agent in controlling the evolution of Ag seeds into nanocrystals with different shapes. Starting with single-crystal seeds (spherical or cubic in shape), we could selectively obtain Ag octahedrons enclosed by {111} facets and nanocubes/nanobars enclosed by {100} facets by adding sodium citrate (Na(3)CA) and poly(vinyl pyrrolid...

In this study, magnetically separable ZnO/CuFe2O4 nanorod particles were synthesized by the green synthesis approach, using rambutan peel extract (Nephelium lappaceum L.) as a capping agent. The samples evaluated photocatalyst for degradation of Rhodamine B dye driven solar light irradiation. XRD patterns represented specific peaks ZnO and CuFe2O4 in composite. SEM TEM images showed rod-like sh...

background and aims. anticariogenic effects of different mouthrinses have been shown previously. in this in vitro study the anticariogenic effects of polyphenol extract of green tea with 0.05% fluoride, 0.2% chlorhexidine and fluoride-chlorhexidine were compared. materials and methods. this in vitro study was performed on 50 maxillary premolars in 5 groups: 1) normal saline; 2) a 10% solution o...
