Bimetallic nanoparticles (to approximately 11 nm diameter) of CuNi and CuCo were prepared by a new synthetic route and the 1:1 atomic ratio of their constituent elements confirmed using STEM-EDS at a single particle level. These nanoparticles, supported on the native oxide layer of a silicon wafer, were studied in situ in a series of reactive gas atmospheres (H2 --> CO or CO/H2 --> O2 --> H2) u...

Copper(II) oxalate grown on carboxy-terminated self-assembled monolayers (SAM) using a step-by-step approach was used as precursor for the electron-induced synthesis of surface-supported copper nanoparticles. The precursor material was deposited by dipping the surfaces alternately in ethanolic solutions of copper(II) acetate and oxalic acid with intermediate thorough rinsing steps. The depositi...

In heterogeneous catalysis, a nanoparticle (NP) system has immediate chemical surroundings with which its interaction needs to be considered, as nanoparticles are typically loaded onto certain supports. Beyond what is known about these interactions, dynamic atomic interactions between the nanoparticle and support could result from the increased energetics at the nanoscale. Here, we show that th...

The paper covers the study of the effects of silver (Ag) and copper (Cu) nanoparticles on wheat-Pseudocercosporella herpotrichoides pathosystem in general and, separately, on their interaction both with the plant and with the pathogen. Plants, treated with nonionic colloidal solutions of biogenic metal nanoparticles of Ag and Cu, have taken seed treatment as stress and have demonstrated the sam...

A new sensitive electrochemical sensor for the detection of copper ions based on the copper ion assisted etching of Au@Ag nanoparticles was developed in this work. Since copper ions could greatly catalyze the etching process of the silver shell of Au@Ag nanoparticles in the presence of thiosulfate solutions, leading to an obvious decrease of the linear sweep voltammetry (LSV) signals of silver,...

The current study emphasizes the process of synthesis of nanoparticles from the natural residue that is rapid and eco-friendly. So we present a simple and eco-friendly biosynthesis of silver nanoparticles using Ficus benghalensis fruit extract as reducing agent, rapid reduction of silver ions is observed leading to the formation of silver nanoparticles in solution. The synthesized nanoparticles...
