In this paper, we report a simple and fast method to produce uniform nano-sized Ag particles that can be dispersed in the oil phase by using oleic acid as solvent and capping agent. Oleylamine, a longchain amine that can act as an electron donor at elevated temperatures and is miscible with oleic acid, was selected as a reductant.

The present study focuses on the preparation of silver/copper bimetallic hybrid nanoparticles by green method from precursor solutions of silver nitrate & copper nitrate and the locally available citrus fruit (lemon) peel extract which behaves as the stabilizing and reducing agent. Initially, the formation of hybrid nanoparticles was noticed in the reaction mixture by colour change.

In the management of burn wounds, antimicrobial and wound healing properties are crucial. In this study, we prepared a three-layer electrospun poly(ε-caprolactone) (PCL) membrane for burn wound dressing. The hydrophobic electrospun PCL layer, embedded with silver nanoparticles (SNPs) (PCL-Ag), was coated with another layer of electrospun plasma-treated PCLAg to enhance the wettability of the membrane.

A portable and simple Raman scattering and photoluminescence spectroscopy system was set up for sensitive and rapid determination of nitrate/nitrite at low concentrations in water samples. The SERS (Surface Enhanced Raman Scattering) e active Ag/ITO substrates were prepared and employed to obtain the enhanced Raman scattering light from the sample.

Three kinds of CueAg composite paste were fabricated. We used 10 mm Cu particles as the main component of the paste as they are significantly cheaper than Ag and Cu nanoparticles. To understand the bonding performance and mechanism, the flake-shape CueAg pastes with a different solvent and a Cu spherical particle with a diameter of 10 mm were separately implemented for the bare Cu bonding.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

This work reports the surface modification of polyacrylonitrile (PAN) fibers by graft copolymerization to ensure the decoration of homogenous and dense Ag nanoparticles. Two facile and subsequent modification processes resulted in a PAN fiber composite with an intact fibrous structure, sufficiently conductive for antistatic application and antibacterial activity. In the first step, some chemically attractive monomers and monomer mixtures, such as acrylic acid (AA), AA-itaconic acid (AA-IA), AA-acrylamide (AA-AAm), were introduced to the fiber surface by grafting.
