With the aim of gauging their potential as conducting or superconducting materials, we examine the crystal structures and magnetic properties of the roughly one hundred binary, ternary, and quaternary Ag(II) and Ag(III) fluorides in the solid state reported up to date. The Ag(II) cation appears in these species usually in a distorted octahedral environment, either in an [AgF](+) infinite chain ...

objective(s): silver nanoparticles (ag nps) are not only specific physical and chemical properties but also are considered for their antibacterial activity and ecofriendly.materials and methods:in this study a simple, cost effective biologically method for ag+reducing to ag nps using echinops extractas a stabilizer, and reducing agent.ag nps were analyzed using uv-vis spectrometry,tem, xrd and ...

‎the annihilator graph $ag(r)$ of a commutative ring $r$ is a simple undirected graph with the vertex set $z(r)^*$ and two distinct vertices are adjacent if and only if $ann(x) cup ann(y)$ $ neq $ $ann(xy)$‎. ‎in this paper we give the sufficient condition for a graph $ag(r)$ to be complete‎. ‎we characterize rings for which $ag(r)$ is a regular graph‎, ‎we show that $gamma (ag(r))in {1,2}$ and...

conclusions silver nanoparticles have high therapeutic activity against mrsa, thus can be suggested as an alternative or adjuvant with antibiotics for mrsa treatment. further studies are required to understand the synergistic effect of ag-nps combinations and to assess the safety and efficacy of new antibiotic-ag-nps combinations. background methicillin-resistant staphylococcus aureus (mrsa) ar...

the aim of this short note is to introduce the concepts of prime and semiprime ideals in ordered ag-groupoids with left identity. these concepts are related to the concepts of quasi-prime and quasi-semiprime ideals, play an important role in studying the structure of ordered ag-groupoids, so it seems to be interesting to study them.
