Effect of Carbon Black and Silver Nanoparticle Loading on the Structural and Thermo-Mechanical Properties of Chitosan-Based Films

Blagg A., Perales-Perez O., Valentin R., University of Puerto Rico-Mayagüez, PR

This work addresses the synthesis and structural and thermo-mechanical characterization of bare and chitosan-based nanocomposite films synthesized via spin coating and sol casting techniques. The dependence of these properties as a function of the nature [...]

Preparation of Ag/TiO2/bamboo charcoal composite based on chemical and electrochemical synthesis: characterization and antibacterial study

Pookboonmee S., Laohhasurayotin K., National Science and Technology Development Agency, TH

A combined function of photocatalysis, antibacterial, and adsorption was introduced as a composite powder in the form of Ag/TiO2/BC. The powder was characterized by SEM, TEM, and XRD for confirmation of the obtained product. The [...]

AuAg-alloy-nanoprobes for specific nucleic acid detection

Doria G., Larguinho M., Dias J.T., Pereira E., Franco R., Baptista P., CIGMH/DCV & REQUIMTE/DQ, PT

Due to their unique optical properties, noble metal nanoparticles, and in particular gold nanoparticles (AuNPs), have been extensively used for the development of new molecular diagnostic assays[1]. These optical properties derive from the characteristic surface [...]

Rapid Metallization of Silver and Copper Nano Inks by Surface Wave Plasma Sintering

Cho J-M, Lee Y.I., Song Y.A., Kim D-H., Kim S.E., Kim T-H., Kim D-H., Kim S.E., Kim T-H., Kim D-H., Kim S.E., Kim T-H., Samsung Electro-mechanics Co. Ltd., KR

Inkjet printing technique of nano-sized silver or copper particles currently has had lots of attention as an alternative to conventional lithography and etching process for electronic devices in view of reducing costs. The inkjet-printed nano [...]

Green Chemistry Derived Nanocomposite of Silver-modified Titania used for Disinfectant

Liu J., Ramirez I., Bashir S., Mernaugh R., Texas A&M University-Kingsville, US

A significant accomplishment of this study centers on developing nanocomposite (NC) materials via green synthesis (GS) techniques for inactivation of prokaryotes like Escherichia coli. The motivations are to: (1) implement fundamental research in nanochemistry for [...]

Developing a Strategy for the Spatial Localisation and Autonomous Release of Silver Nanoparticles within Smart Implants

Newton L.A.A., Sharp D.G., Leslie R., Davis J., Nottingham Trent University, UK

A novel approach to the controlled release of silver nanoparticles from a solid state repository within microdevice/micro fluidic architectures is presented. The dynamics of their formation, mechanism and influence on particle formation and release characteristics [...]

Formation and stabilization of gold and silver clusters and nanoparticles in mordenites

Pestryakov A., Bogdanchikova N., Tuzovskaya I., Avalos M., Farías M.H., Tomsk Polytechnic University, RU

Supporting silver and gold on mordenites by ion-exchange method with further reduction with H2 leads to formation of neutral and charged metal clusters inside zeolite channels as well as metal nanoparticles on external surface of [...]

Green Chemistry Used in the Synthesis and Characterization of Silver and Gold Nanoparticles

Vallejo R., Segovia P., Elizondo N., Vázquez O., Coello V., Castaño V., Universidad Autonoma de Nuevo Leon, MX

Gold (Au) and silver (Ag) nanoparticles have a diversity of interesting properties between which they emphasize the electrical ones, optical, catalytic and the applications in biomedicine like antibacterial and antiviral, same that depend on their [...]

Formation mechanism of copper-silver metal nanoparticle encapsulated in carbon shell

Kang H.Y., Wang H.P., Huang C.H., Tsai C.K., National Cheng Kung University, TW

The formation mechanism of nanosize copper-silver encapsulated in the inert carbon shell (CuAg@C) has been studied by in-situ small angle X-ray scattering (SAXS) spectroscopy. SAXS is a very useful method in studies of electron density [...]

Surface Enhanced Raman Utilizing Magentic Core Silver Shell Nanoparticles

Glaspell G.P., UACE ERDC, US

SERS is an extremely sensitive technique exploited in laboratory investigations to provide single molecule detection. In sensor applications, this sensitivity has not been fully realized in part due to the low scattering efficiency. We hypothesize [...]
