in this work, ag-cu nanoparticles (with different percentages of copper, 10%, 25%, 50%, 75% cu) were synthesized by wet chemical method. copper(ii) sulfate and silver nitrate were taken as metal precursors, ascorbic acid as reducing agent and anhydride maleic (ma) as a modifier. the prepared nanoparticles were characterized by means of x-ray diffraction (xrd) technique and scanning electron mic...

in this paper, a novel method of producing bi-metallic alloy nanoparticles at low temperatures using hydrogen bombardment of thin films, deposited on glass substrates, is introduced. optical and morphological characteristics of the nanoparticles were extensively studied for various conditions of plasma treatment, such as plasma power density, temperature, duration of hydrogen bombardment, thick...

This paper reports the structural and optical properties and comparative photocatalytic activity of TiO2 and Ag-doped TiO2 nanoparticles against different bacterial strains under visible-light irradiation. The TiO2 and Ag-doped TiO2 photocatalysts were synthesized by acid catalyzed sol-gel technique and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-vis spe...

Chlamydia trachomatis is a very common sexually transmissible infection in both developing and developed countries. A hallmark of C. trachomatis infection is the induction of severe inflammatory responses which play critical roles in its pathogenesis. Antibiotics are the only treatment option currently available for controlling C. trachomatis infection; however, they are efficacious only when a...

Bio-chemical reduction method was employed to synthesise the silver nanoparticles (Ag NPs) by aging the mixture of the aqueous extract of the Trachyspermum Ammi (TA, Ajwain) seeds and AgNO3 solution at different time interval. Reaction time of AgNO3 and TA could accelerate the reduction rate of Ag and affect AgNPs size and concentration of NPs. X-ray diffraction (XRD) studies confirms the forma...

BACKGROUND The increasing use of nanoparticles and nanocomposite in pharmaceutical and processed food industry have increased the demand for nontoxic and inert metallic nanostructures. Chemical and physical method of synthesis of nanostructures is most popular in industrial production, despite the fact that these methods are labor intensive and/or generate toxic effluents. There has been an inc...

Objectives . The study aimed to synthesize the multifunctional materials silver-added titanates via reduction of sol-gel fabricating (Fe 2 TiO 5 and NiTiO 3 ) with Jasminium subtriplinerve Blume leaf extract. Methods physicochemical characteristics obtained were determined by X-ray diffraction, energy dispersive X-Ray spectroscopy, Raman Brunauer–Emmett–Teller specific surface area, scanning el...

The formation of Ag nanoparticles by the addition of Ag atoms to helium droplets has been investigated. The resulting nanoparticles were then imaged by transmission electron microscopy after being deposited on a thin solid surface. In large helium droplets chains of Ag nanorods were observed similar to recently reported track-like deposits [Gomez et al., Phys. Rev. Lett., 2012, 108, 155302]. Ho...

Background and Aims: Although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. Therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (Ag NPs) and magnesium oxide nanoparticles (MgO NPs) on the cardiomyocytes. Materials and Methods: Cardiomy...

The present paper describes the preparation and characterization of Polyvinyl Alcohol-Polypyrrole-Silver Nanocomposite (PVA-PPy-Ag NC) films. The prepared films were conducting, freestanding, flexible, and robust. Silver nanoparticles (Ag NPs) were synthesized from an aqueous solution of silver nitrate using trisodium citrate as a reductant. The casting solution for the films was prepared by in...
