In this paper, three techniques to obtain capped magnetite nanoparticles were compared. In the formation of magnetite nanoparticles via the co-precipitation route, capping agents were introduced pre-, simultaneously with, or post-addition of the precipitating agent, ammonia. The amino acids L-glutamine and L-glutamic acid were used as the capping agents. Characterization via TEM, pXRD, EDX, and...

We report a rapid one-pot supercritical fluid approach to prepare the desired size and morphology controlled LiMPO(4) nanocrystals, using oleylamine as both capping and reducing agent.

In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...

in this paper, tin dioxide nanoparticles were synthesized by a fast and simple co-precipitation method. for sno2 preparation, we used ammonia as precipitation agent and bis (acetylacetone) ethylene diamineas as capping agent. by changing in sncl4, acacen mole-ratio different morphologies were obtained. this semiconductor nanostructure has photo-catalyst activities and can degrade organic dyes a...

introduction: the aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (mta) and 0.2% chlorhexidine (chx) mixture to pure mta, as a pulp capping material. methods and materials: the pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with mta or mta+0.2% chx. after 2 months the animals were sacrificed and the teeth were pre...

Chemical reduction technique was used to synthesize nickel powder using hydrazine hydrate as reducing agent, nickel chloride hexahydrate as precursor and polyvinylpyrrolidone (PVP) as capping agent in ethylene glycol medium. Experiments were carried out with mole ratios 13:1 and 20:1 of hydrazine to nickel chloride hexahydrate by keeping the amounts of ethylene glycol and NaOH as constant. Vari...

Abstract Nanomaterials are frequently employed in daily life goods, including health, textile, and food industry. A comprehensive picture is lacking on the role of capping agents, added ligand molecules, case nanoparticle reactions degradation aqueous solutions, like surface waters or biofluids. Here, we aim to elucidate agent influence reactivity probing two commonly agents citrate polyvinylpy...

A seed-mediated approach was applied to synthesize gold (Au) nanoparticles (NP) by using twin tail alkylammonium cationic surfactants such as 12-6-12 and 12-0-12 as capping agents in aqueous phase at ambient conditions. The growth of Au NP was monitored by changing the amount of seed. Spherical NP (10–50nm) and nanorods (aspect ratio ) 2–3) were obtained in the presence of 12-6-12 as capping ag...

cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants ofcadmium acetate and sodium sulfide in the presence of thioglycerol (tg) as capping agent in ethanolsolvent. different nanoparticle sizes and size distribution were obtained through varying the molaritiesof thioglycerol. at higher tg concentration, synthesis provides a nearly monodisperse nanoparticl...
