The recent antimicrobial resistant to the present antibacterial agents has been biggest problem in treatment of infection. Over years, various strategies implemented overcome resistance available antibiotic agents. In regards this, phytochemical found plants like Allium cepa, which exhibited potent activity used by researchers as natural products fight against bacterial resistance. cepa also kn...

This study is a green approach for the synthesis of silver nanoparticles (AgNPs) using morphine ampoules (MO) as reducing and capping agents. The toxicity effects of prepared particles were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay on breast cancer cells. The spherical AgNPs with the average size of 50nm were synthesized and studied by UV–visible s...

Silver nanoparticles (AgNPs) have become popular due to their unique properties that can be used as biosensors, composite fibers, semiconductor materials, and other medical applications. Green synthesis of AgNPs using natural reagents from plant extract offers advantages an efficient environmentally friendly technique by which the compounds perform bio-reductor for silver ions capping agent sta...

In this work the Origanum vulgare leaf extract was used to green synthesis of Ag nanoparticles (NPs) supported on Hazelnut shell as an environmentally benign support. The Ag NPs/Hazelnut shell as an effective catalyst was prepared through reduction of Ag+ ions using Origanum vulgare leaf extract as the reducing and capping agent and Ag NPs immobilization on Hazelnut shell surface in ...

Background: After indirect capping, injured odontoblasts generate reactionary dentin, whereas after direct capping of a pulp exposure pulp, cells stimulate the formation of reparative dentin. The aim of this study was to evaluate and compare the effects of two direct capping agents on pulp tissue reactions: Hydrogel (a bovine serum albumin (BSA)/glutaraldehyde,) and Dycal (a calcium hydroxide-b...

In the field of nanoscience and nanobiotechnology, use plant extracts in synthesising metal sulphide nanoparticles has lately come to light as an intriguing issue with several benefits over traditional physicochemical methods. Herein, bio-mediated novel ?-In2S3 quantum dots were fabricated using Camellia sinensis var. assamica (tea) leaf extract a stabilising capping agent through facile solvot...

Herein we have reported the fabrication of green SnS2 (g-SnS2) granules via a facile precipitation technique employing Ocimum sanctum (Tulsi) extract as stabilising and capping agent. The prepared g-SnS2 nanoparticles were characterised through XRD, UV-DRS, PL, BET, XPS, SEM TEM for their surface morphology physicochemical properties. It showed enhanced Advanced Oxidation Process (AOP) assisted...

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)16COO...

Metal nanostructures have attracted great attention in various fields due to their tunable properties through precisely tailored sizes, compositions and structures. Using mesoporous silica (mSiO2) as the inorganic capping agent and encapsulated Pt nanoparticles as the seeds, we developed a robust seeded growth method to prepare uniform bimetallic nanoparticles encapsulated in mesoporous silica ...

The present invention is directed to a method for powder coating a metal substrate using a low-melt polyamic acid (PAA) polymer that readily imidizes to polyimides. These low-melt PAAs have been shown to be useful in resins applied as powder coatings to metal surfaces. The resin includes an end-capping material capable of providing crosslinking functionality to at least one end of the low-melt ...
