The electrocarboxylation reaction is an attractive means to convert CO 2 into valuable chemicals under ambient conditions, while it still suffers from low efficiency due the high stability of . In this work, we report a double activation strategy for simultaneously activating and acetophenone by silver-doped CeO (Ag-CeO ) nanowires, featuring as effective electrocatalyst with Compared Ag foil, ...

Titanium is a key biomedical material due to its good biocompatibility, mechanical properties and corrosion stability, but infections at the implantation site still pose a serious threat. One approach to prevent infection is to improve the antimicrobial ability of the coating material. Silver-doped hydroxyapatite (Ag/HAP) nanoparticles were synthesized by a new modified precipitation method. Th...

Surface-enhanced Raman scattering (SERS) is ideally suited for probing and mapping surface species and incipient phases on fuel cell electrodes because of its high sensitivity and surface-selectivity, potentially offering insights into the mechanisms of chemical and energy transformation processes. In particular, bimetal nanostructures of coinage metals (Au, Ag, and Cu) have attracted much atte...

The purpose of this research was to study the effect of doped Ag on phase transformation, morphology and photocatalytic activity of TiO2 powders. The composites powders were prepared by sol-gel method via calcinations at a temperature 400 °C for 2 h with a heating rate of 10 °C/min. The microstructure and crystallite size of TiO2 and TiO2-Ag powders were characterized by XRD, EDX and SEM. Final...

The ternary nanocomposite of silver particles decorated N/S dual-doped graphene and molybdenum disulfide microspheres (Ag-MoS 2 /NSG) is prepared by hydrothermal-chemical reduction method with quantum dots (GQDs) as additives oxide, sodium molybdate nitrate main raw materials. For comparison, the binary composites Ag-MoS , Ag-NSG MoS /NSG are also discussed. In addition, physicochemical electro...

The wetting and brazing of Y3Fe5O12 (YIG) ceramics with a Ag–8CuO–2TiO2 filler was investigated for the first time. For comparison, wettability Ag–10CuO on YIG similarly investigated. has an equilibrium contact angle approximately 31 °C substrate at 1000 °C; thus, its is excellent. Moreover, exceeds that Ag–10CuO. microstructure interfacial structure between were determined using scanning elect...

Abstract We have studied reflection spectra of dye-doped and undoped polymers deposited onto Ag Au substrates found anomalous dips in the UV spectral range. On top substrates, ? ? 375 nm were observed PMMA, PVP, PS as well PMMA doped with Rh590 HITC laser dyes. In silver-based samples, positions close to singularities refractive indexes surface plasmon polaritons (SPPs) propagating at interface...
