Abstract Zinc sulfide (ZnS) nanoparticles are produced in this study utilizing a simple wet‐chemical precipitation procedure using polyethylene glycol (PEG) as capping agent. To analyze the structural, morphological, electrical, and electronic properties of material, ZnS nano powder is studied X‐ray diffraction (XRD), scanning electron microscopy (SEM), FTIR, UV–visible absorption spectroscopy,...

BACKGROUND Permanent teeth pulp exposures have traditionally been treated with calcium hydroxide pulp capping. The aim of this study was to investigate the response of human pulp tissue which were mechanically exposed to a new material, Propolis and compare it with two existing and commonly used pulp capping agents (mineral trioxide aggregate and Dycal). METHODS Thirty-six intact human premol...

Chitosan coated iron nanoparticles were synthesized by co-precipitation method and also Nanoparticles evaluate the effect of surface coating on stability toxicity nanoparticles. FTIR amino groups acted as a capping site for Iron stabilization. Invitro cytotoxicity is dependent dose-based their reduction was observed in SKMEL cancer cells administered with different concentration samples. I50 va...

The green synthesis of ZnO nanoparticles was carried out using a natural capping agent, Sapindus rarak DC rinds extract at low-temperature calcination and environmentally friendly solvent. mixture Zn(CH3COO)2, NaOH, sonicated for 4 h room temperature. low temperature, 95oC 8 h, resulted in pale brown powder. XRD SEM were used to confirm the structure analyze morphology respectively. pattern cor...

objective: bioactive glass is often used as a filler material for repair of dental bone defects. in different studies osteogenic potential of this material was proved, but its dentinogenesis property is in doubt. the purpose of this study was to evaluate the histological pulp responses of calcium hydroxide and bioactive glass placed directly on exposed pulp tissues. materials and methods: twent...

Highly stable dispersions of nanosized silver particles were synthesized using a straightforward, cost-effective, and ecofriendly method. Nontoxic glucose was utilized as a reducing agent and poly-α, γ, L-glutamic acid (PGA), a naturally occurring anionic polymer, was used as a capping agent to protect the silver nanoparticles from agglomeration and render them biocompatible. Use of ammonia dur...

OBJECTIVE To investigate the impact of tracheostomy tube capping on swallowing physiology in stroke patients with dysphagia via videofluoroscopic swallowing study (VFSS). METHODS This study was conducted as a prospective study that involved 30 stroke patients. Then, 4 mL semisolid swallowing was conducted with capping of the tracheostomy tube or without capping of the tracheostomy tube. The f...

our aim in this work is the synthesis and study optical and structural properties of gold nanoparticles.gold (iii) chloride trihydratewas taken as metal precursor, ascorbic acid at the presence of an appropriate amount of naoh as reducing agent and polyvinylpyrrolidonek-30 (pvp k-30) as a stabilizing and capping agent. the reaction was performed in high-speed stirring rate at room temperature.s...

In this paper, we report structural and optical properties of Mn doped ZnS nanoparticles, having average size 2.44–1.60 nm have been synthesized by co-precipitation method using Thioglycolic Acid as external capping agent. Zinc blende crystal structure ZnS:Mn nanoparticles has been confirmed by the X-ray diffraction studies. Absorption spectra have been obtained using UV-Vis spectrophotometer t...
