Green synthesis of Au-Ag nanoparticles using Mentha piperita and effects of Au-Ag alloy nanoparticles on the growth of Mentha piperita under salinity stress
Salinity stress reduces plant metabolic activity, which reduces plant growth in saline environments. this study aimed to investigate the effect of salinity stress as one of the limiting factors of plant growth and the effect of nanoparticles on stress conditions as one of the auxiliary factors in plant control against stressful conditions by studying physiological factors such as soluble sugars...
متن کاملSynthesis and characterization of Au@Pt nanoparticles
Aucore-Ptshell (Au@Pt) nanoparticles were synthesized at room temperature by reducing K2PtCl6 with hydrogen in the solution containing Au colloids and polyvinylpyrrolidone (PVP). The particles obtained were characterized with UV-Vis, TEM and XPS techniques. UV-Vis spectra show that the surface plasmon absorption feature of Au colloids is significantly reduced with increasing the amount of reduc...
متن کاملStructural analysis and shape-dependent catalytic activity of Au, Pt and Au/Pt nanoparticles
Metallic nanoparticles of Au, Pt and Pt/Au have been synthesized using a chemical reduction approach. The structural characterization of these metallic nanoparticles has been carried out using conventional transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HR-TEM) techniques. HR-TEM images of Pt nanoparticles reveal their fcc-like structures, in the [10...
متن کاملFirst - principle study of Au
The geometries, stabilities, electronic, and magnetic properties of AunScm (n= 1–7, m=1,2) clusters have been systematically investigated by density functional theory. It is shown that the most stable structures of AunSc (n=1–7) clusters favor planar structure and Sc atom is prone to occupy the center site of Au atoms ring. For AunSc2 clusters, the 3d configurations become the lowest energy str...
متن کاملElectrocatalytic properties of Au@Pt nanoparticles: effects of Pt shell packing density and Au core size.
A detailed study of electrocatalytic properties of Au@Pt nanoparticles (NPs) as functions of Pt shell packing density and Au core size in terms of CO/methanol oxidation and oxygen reduction reactions is reported here. While most samples studied showed inferior catalytic activities to those of the commercial Pt black that fall reasonably well in a d-band-center up-shift (i.e., stronger surface b...
