The nanocomposite consists of the Ag as a core and Pt as shell on the surface of graphene nanosheets (Ag/Pt-G) was synthesized with a simple method and used as a novel electrochemical platform for an efficient catalyst for oxidation of the ethanol, methanol and formic acid. The morphology and electrochemical properties of Ag/Pt-G nanocomposite were investigated by TEM, X-ray diffraction, and vo...

Silver-impregnated membrane was facilely prepared by ex situ silver nanoparticles (NPs) blending method using polyethersulfone (PES) as the base polymer. A total of three membranes [F1(S0), F2(S0.5) and F3(S2.0)] were fabricated at different weight percentages of polymer and silver (Ag) loadings to compare their effects on membrane morphological and performance properties. All membrane types we...

in this paper, we introduce a considerable machinery which permits us to characterize a number of special (fuzzy) subsets in ag -groupoids. generalizing the concepts of (,q) -fuzzy bi-ideals (interior ideal), we define ( , ) k q -fuzzy bi-ideals, ( , ) k q -fuzzy left (right)-ideals and ( , ) k q -fuzzy interior ideals in ag -groupoids and discuss some fundamental aspects of these i...

let $r$ be a commutative ring with identity and $mathbb{a}(r)$ be the set   of ideals of $r$ with non-zero annihilators. in this paper, we first introduce and investigate the principal ideal subgraph of the annihilating-ideal graph of $r$, denoted by $mathbb{ag}_p(r)$. it is a (undirected) graph with vertices $mathbb{a}_p(r)=mathbb{a}(r)cap mathbb{p}(r)setminus {(0)}$, where   $mathbb{p}(r)$ is...

The nanocaps array of TiO₂/Ag bilayer with different Ag thicknesses and co-sputtering TiO₂-Ag monolayer with different TiO₂ contents were fabricated on a two-dimensional colloidal array substrate for the investigation of Surface enhanced Raman scattering (SERS) properties. For the TiO₂/Ag bilayer, when the Ag thickness increased, SERS intensity decreased. Meanwhile, a significant enhancement wa...

Following exposure to a diet containing control (no added Ag), AgNO3, Ag NPs or Ag2S NPs, Ag-containing particles were found in organs of all treatments, with the highest concentrations following AgNO3 NP.

silver nanoparticles (ag nps) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. present study compares the tissue levels of ag nps in different organs of guiana pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the ag nps tissue levels. before toxicological assessments,the ...

objective(s):   metal nanoparticles (nps) offer a wide variety of potential applications in pharmaceutical sciences due to the unique advances in nanotechnology research. in this work, bimetal ag-au alloy nps were prepared and their combinations with other antibiotics were tested against staphylococcus aureus.   materials and methods: firstly, ag-au alloy nps with au/ag molar ratio of 1:1 was f...
