Silver is one of the most popular material in last decade. Silver nanoparticles have been hitting the headlines for a few years now, both as a smart new technology for preventing bacterial infection, and as a potential new health and environmental threat.

part from antibacterial properties,there are several application area of silver nanoparticles since silver has remarkable characteristics.Silver nanoparticles are nanoparticles of silver of between 1 nm and 100 nm in size.Silver nanoparticles have unique optical, electrical, and thermal properties and are being incorporated into products that range from photovoltaics to biological and chemical sensors. The unique properties of silver nanoparticles make them ideal for numerous technologies, including biomedical, materials, optical, and antimicrobial applications, as well as for use in nanotoxicology studies. Silver nanoparticles some spicific properties such as;

- high electrical conductivity,

- high stability,

- low sintering temperatures.

Also thanks to these unique properties of silver nanoparticles, it can be utilized in several fields such as molecular diagnostics and photonic devices, which take advantage of the novel optical properties of these nanomaterials. Moreover, silver nanoparticles commonly used in antimicrobial coatings, textiles, diagnostic, wound dressings,optics and biomedical devices now contain silver nanoparticles that continuously release a low level of silver ions to provide protection against bacteria.

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Magnesium Oxide Nanoparticles/Nanopowder and Applications

General Information about Magnesium Oxide Magnesium oxide which has the chemical formula of MgO, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of Magnesium. It is a white powder at room temperature. Magnesium Oxide has very high melting point (2825 o C) and boiling point (3600 o C). Magnesium Oxide Nanoparticles/Nanopowder and Usage Areas Magnesium Oxide nanoparticles/nanopowder can be used in many different areas.
