What is nanotechnology in computer?

Nanotechnology, in the context of computer science, is a type of engineering geared toward building electronic components and devices measured in nanometers, which are extremely tiny in size and structure.

What are nanowires used for?

Nanowires are extensively used in nanoelectronic devices as connectors for the transportation of electrons. Cobalt, copper, silicon, and gold have been utilized to make nanowires. Chemical vapor deposition is used for the production of nanowires (Njuguna et al., 2014).

How are silver nanoparticles used in medicine?

AgNPs are mainly used for antimicrobial and anticancer therapy, and also applied in the promotion of wound repair and bone healing, or as the vaccine adjuvant, anti-diabetic agent and biosensors.

Why silver is used in nanotechnology?

Because silver, like other noble metals, exhibits a size and shape dependent optical effect known as localized surface plasmon resonance (LSPR) at the nanoscale, the ability to synthesize Ag nanoparticles in different shapes vastly increases the ability to tune their optical behavior.

There are different types of nanowires in technology, they are: Metallic nanowires, semiconducting nanowires, insulating nanowires. The structure of nanowires is very simple, made of variety of materials.

WHAT IS nanowires in nanotechnology?

nanowire, thin wire, generally having a diameter less than or equal to 100 nanometers (1 nm = 1 × 10−9 metre). The first nanoscale quantum-well wire (a thinly layered semiconductor structure) was developed in 1987 by scientists at Bell Laboratories.

Why are silver nanoparticles better than gold?

Silver nanoparticles produce a stronger plasmon resonance than gold nanoparticles it can be due to the large reflectivity from the metal surface. TEM images indicate that change in the size of nanoparticles with increasing the laser fluence is in good agreement with the Mie theory.

Nanopowders can be defined as powdered materials with individual particles in nanometer scale or materials with crystalline in nanometer scale. Sergey Yu. Sokovnin, Michael G. Zuev, in Engineering of Nanobiomaterials, 2016

How does nanopowder affect occupational safety?

Occupational safety is heavily compromised due to less control over manufacturing and other processes when nanopowder is supplied by other laboratories or external sources. Moreover, consumers use nanopowder more often in congested places. Jiyong Wang,

What are the main nanosized powder production technologies?

The main nanosized powder production technologies, including the condensation technique, chemical precipitation from solution, the spray conversion method, plasmochemical synthesis, high-energy disintegration, and electrical explosion, are characterized.

What happens during consolidation of nanopowders during sintering?

During consolidation of nanopowders, significant changes usually occur in the grain structure as well as in the type and densities of lattice defects. Most sintering processes apply high pressure and temperature in order to minimise the remaining porosity in the consolidated materials.
