Combined CV studies and UV-Vis-NIR spectroelectrochemical investigations revealed an unusual stability of the pand n-doped PMOThOD in the wide potential window of 4 V. The n-doping process occurs in this polymer down to 2.7 V (vs. Ag/Ag) in a non-destructive way with the characteristic development of the o3 transition as a function of the doping level. In situ electronic transport studies revea...

Based on cataluminescence from plasma-assisted catalytic oxidation, a low temperature CO sensor was fabricated. With Ag doped alkaline-earth catalyst as sensing element, air as discharge gas, carrier gas and oxidant supplier, significant cataluminescence was achieved at low temperature, demonstrating a potential low-consumption and portable sensor of CO.

• A high ZT of ~0.52 is achieved in n -type (Ag, Sn) co-doped CoSb 3 at 623 K. Extensive characterizations and computational results confirm both Sn In as fillers prefer to occupy the interstitial sites lattice. The Fermi level moved into conduction bands increase density state after doping, resulting power factor. Young modulus hardness sample enhanced Ag indicating its potential for applying ...

Under microwave radiation, Ag(+)-doped CdS semiconductor nanocrystals with high photoluminescence quantum yield (approximately 58%) and a surprisingly large optical window (480 to 630 nm) are formed controllably using a center-doping strategy and are optimized through a green approach in pure water solution.

A novel Ag/AgBr/BiOBr hybrid was prepared by a rational in situ ion exchange reaction between BiOBr hierarchical microspheres and AgNO(3) in ethylene glycol followed by light reduction, which displayed superior visible light driven photocatalytic activities in sterilization of pathogenic organism and degradation of organic dye compared to N-doped P25.

The room temperature stability of nanometer-sized silver clusters in silica matrices has been investigated by following the temporal evolution of their surface plasmon absorption. Ag clusters in SiO2 were prepared by either annealing silica samples doped with atomic silver or by co-deposition of pre-formed clusters of defined size. Clusters were found to be unstable at ambient conditions on a t...

TiO2 nanoparticles synthesized by the sol-gel method and doped with Ag were characterized SEM, EDAX, FTIR, BET, XRD TEM, then tested in photocatalytic degradation of methylene blue (MB) under UV irradiation. The experimental results indicate that average size raw particles was 10 nm, their increased calcination. MB on nanostructured TiO2-Ag shows a high efficiency upon addition photosensitizer....

This study investigated the feasibility of using Ag-TiO2 photocatalyst supported on glass fiber (Ag-TiO2/GF) prepared by a sol-gel method as an indoor air germicide. An experimental model was designed to investigate the bacterial disinfection efficiency of Staphylococcus (Staph), the most popular bacterium in hospitals in Korea, by the Ag-TiO2/GF photocatalyst. The silver content in Ag/TiO2 was...
