Abstract:

Silver metal nanoparticles were immobilized in chitosan/carboxymethylcellulose/BMI.BF4(1-n-butyl-3-methylimidazolium tetrafluoroborate ionic liquid) (CS/CMC/IL) to form polymeric membrane with 20 μm thickness. The CS/CMC/IL polymeric membrane was prepared using a simple solution blending method. Irregularly shaped Ag(0) nanoparticles with monomodal size distributions of8.0±0.4 nm Ag(0) were immobilized in the membrane. The presence of small Ag(0) nanoparticles induced an augmentation in the CS/CMC/IL film surface areas. The CS/CMC/IL membrane containing Ag(0) showed increase antimicrobial acti

Abstract:

In this work, highly mesoporous Ag/ZnO was rapidly developed from rice husk, a cheap agricultural biomass with urea as the reducing agent at acidic medium. A facile and cheap sol-gel method combined with calcination was employed to produce Ag/ZnO 0-D nanoparticles. TEM investigation revealed the formation of spherical and discreet nanoparticles with an average particle size of 13.55 nm. Ag/ZnO with semi-crystalline nature was confirmed from the high-angle XRD study. A type IV isotherm with high Brunauer–Emmett–Teller surface area of 416.78 m2g-1was exhibited by Ag/ZnO nanoparticles.

In this study, Ag was loaded onto ZnO, which is non-toxic and inexpensive, can improve the electron–hole separation, and has a significant catalytic potential.

ZnO nanoparticles are semiconductor materials that can act as a photocatalyst to successfully decompose synthetic dye waste. Unfortunately, electron-hole recombination reduces deterioration efficiency. Adding noble metals, such as Ag nanoparticles, to ZnO can boost its photocatalytic activity. The inclusion of SiO2 prevents ZnO from clumping together, resulting in a wider contact area with synthetic dye waste and a better degrading efficiency value. The effects of SiO2 content in ZnO/Ag/SiO2 nanocomposites, ranging from 0 to 5 %wt, on photocatalytic activity have been investigated in this stud

Polyaniline (PANI) is recognized as one of the most important conducting polymers due to its high conductivity and good stability. In this paper, polyaniline/silver (PANI/Ag) nanocomposites were synthesized by in-situ polymerization of aniline using ammonium peroxydisulphate (APS) as oxidizing agent with varying concentration of Ag nanoparticles colloids (0 ml, 25 ml and 50 ml). Silver nanoparticles were synthesized separately in colloidal form from silver nitrate (Ag2NO3) with the help of reducing agent sodium borohydride (NaBH4). The PANI/ Ag nanocomposites were characterized by XRD, SEM, AF

Abstract:

Ag is abundant in nature and is employed in practically every aspect of life. Furthermore, Ag+ contamination poses a severe hazard to human and environmental health due to the extensive usage of Ag products. Traditional Ag+ detection techniques include drawbacks such as high operational costs, sophisticated operating units and instruments, and strong technical demands. The use of fluorescence copper nanoparticles in pollution detection has received a lot of attention in recent times. The development of copper nanoparticles and the detecting of Ag+ are the major topics of this research. Utilizi

Ag-doped ZnS nanoparticles were prepared by hydrothermal synthesis from the raw powders of thiourea, zinc acetate and silver nitrate. The effects of Ag[Formula: see text] on the structural, morphological, composition, elemental analysis and luminescence properties were investigated. The results showed that the powders were all found in the cubic sphalerite structure with an average particle size of approximately 40 nm. In addition, various Ag[Formula: see text] doping concentrations (0, 0.5, 1, 3, 4, 7 and 10 at.%) were selected to study the optical properties of the ZnS nanoparticles. It was

Abstract:

The photochemistry of aromatic ketones through the Norrish type I cleavage of benzoins and via photoreduction generates ketyl radicals that readily reduce many metal ions, including silver and gold. Reduction to Au(0) and Ag(0) leads to the spontaneous formation of nanoparticles (NPs) in aqueous or micellar solutions. Careful consideration of kinetic factors to minimize triplet quenching by metal ions can lead to rapid NP generation. These materials are quite stable and have interesting reactivities due to the essentially unprotected characteristics of the surface.

Abstract:

This study explores the resistive switching (RS) behavior and conduction mechanisms of Ag/SF-Ag NP/Si memristors with varying Ag NP concentrations. I-V measurements confirm stable RS characteristics across 100 cycles, with consistent set and reset voltages. Increasing Ag NP concentration enhances conductive filament formation, leading to sharper switching transitions and a higher HRS/LRS ratio, w-hich increases from 43 (0 wt% Ag NP) to 4.6 × 104 (10 wt% Ag NP). Log(I)-log(V) analysis reveals a conduction transition from Ohmic to Poole–Frenkel mechanisms, indicating improved charge percolation.

The prepared materials retained the anatase structure and contained a mixture of Ag0 and AgI species. Samples exhibited extended light absorption to the visible region. The effect of Ag loading on TiO2 is studied for the photocatalytic reduction of CO2 to CH4 in a gas–solid process under high-purity conditions. It is remarkable that the reference TiO2 used in this work is entirely inactive in this reaction, but it allows for studying the effect of
