We report the controlled alloying, oxidation, and subsequent reduction of individual AgAu nanoparticles in the scanning transmission electron microscope (STEM). Through sequential application of electron beam induced oxidation and in situ heating and quenching, we demonstrate the transformation of Ag-Au core-shell nanoparticles into: AgAu alloyed, Au-Ag core-shell, hollow Au-Ag2O core-shell, an...

The interfacial bonding utilizing Ag2O-derived silver nanoparticles was evaluated using TEM observation and molecular dynamics simulation. The TEM observation reveals that the crystal orientation of the sintered silver corresponded to that of the gold substrate. This is considered that the epitaxial layer of silver was formed through in-situ formation of silver nanoparticles from Ag2O paste, an...

Fast ion conducting (FIC) glasses of composition 66%AgI-[MAg2O-F{(F1)B2O3-(F2)TeO2}] were prepared by melt quenching technique. Here M/F ratio was varied from 0.0 to 2.0 in steps of 0.25 for fixed values of F1& F2. The prepared samples were characterized by X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) experiments to understand their structure. Electrical studies of the prepared...

A Ag2S-Ag2O-Ag/poly-2-aminobenzene-1-thiol (P2ABT) nanocomposite was prepared using the photopolymerization reaction AgNO3 as an oxidant. The size of about 40 nm, in which morphology confirmed TEM and SEM analyses. functional groups Ag2S-Ag2O-Ag/P2ABT were FTIR; also, XRD inorganic Ag2S, Ag, Ag2O formation. This has great performance supercapacitor applications, with it tested acidic (1.0 M HCl...

In gas-insulated switchgear (GIS), partial discharge (PD) can be monitored by detecting sulfur hexafluoride-nitrogen (SF6-N2) decomposition components. this paper, silver oxide (Ag2O) modification was introduced to improve the gas-sensing properties of graphene-like indium nitride (InN). The adsorption process NO2, SO2F2, SOF2 and SOF4 on Ag2O-InN simulated based first principles calculation de...

In this study, we have investigated variations in the potential of floating and submerged leaves of longleaf pondweed (Potamogeton nodosus) to withstand silver ion (Ag+)-toxicity. Both floating and submerged leaves changed clear colorless AgNO3 solutions to colloidal brown in the presence of light. Transmission electron microscopy revealed the presence of distinct crystalline Ag-nanoparticles (...

Green synthesis of bimetallic oxide nanocomposite with leaf extract Eichhornia crassipes (1) is attracted much in recent researchers. The as-synthesized CuO/Ag2O/Ext (2) and CuO/Ag2O NCPs (3) were characterized by UV-Vis, FT-IR, SEM, XRD, TGA. disc diffusion method was used to assess the antibacterial potential (1), (2), against a total four human pathogens bacteria. S. aureus epidermides growt...

An Ag/AgCl reference electrode that is built into commercially available pH electrodes leaks its internal KCl solution via a liquid junction. This leakage disadvantageous because the test contaminated by trace amount of solution. The applicability Ag2O-TeO2 glasses to for sensors was investigated in this study. effects Ag2O content and heat treatment on sensitivity these glass/stainless steel w...
