Transition Metal Nanoparticles

Transition Metal Nanoparticles The elements in the periodic table are often divided into four categories: (1) main group elements, (2) transition metals, (3) lanthanides, and (4) actinides. The main group elements include the active metals in the two columns on the extreme left of the periodic table and the metals, semimetals, and nonmetals in the six columns on the far right. The transition metals are the metallic elements that serve as a bridge,...

Organic Compounds

ORGANIC COMPOUNDS Organic compounds, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides. See chemical compound. The term ‘organic’ was originally coined to describe molecules associated with living organisms....

Indium Arsenide Nanoparticles

Indium Arsenide Nanoparticles InAs is a semiconductor material made of arsenic and indium. The semiconductor has a melting point of 942 °C and appears in the form of grey crystals with a cubic structure. It is very similar to gallium arsenide and is a material having a direct bandgap. Indium arsenide is popular for its narrow energy bandgap and high electron mobility. InAs, or indium monoarsenide, is a semiconductor composed of indium and arsenic....

Colloidal Silica (Silicon Dioxide Nanoparticles Dispersion)

COLLOIDAL SILICA - SiO2 Nanoparticles Dispersion Colloidal Silica is suspensions of silicon dioxide nanoparticles in water or various organic solvents such as ethanol or mineral oil. Nanoshel manufactures oxide nanopowders and nanoparticles with typical particle sizes ranging from 10 to 200nm and in coated and surface functionalized forms. Nanoparticles have some special properties in optical, electric, thermal, and magnetic aspects. SiO2 is not...

CuO Dispersion (Copper Oxide Dispersion)

CuO DISPERSION CuO Dispersion: Nanodispersion are composites consisting of solid nanoparticles with sizes varying generally from 1 to 100 nm dispersed in heat transfer liquids such as water, ethylene glycol, propylene glycol and so on. In the last decade, nanofluids have gained significant attention due to their enhanced thermal properties. A great deal of energy is expended heating industrial and residential buildings in the cold regions of the...

ZnO Dispersion (Zinc Oxide Dispersion)

ZnO DISPERSION ZnO Dispersion: A stable colloidal dispersion is expected to remain without sedimentation even after prolonged periods of storage. The settling behavior of dispersions depends mainly on the size and density of the dispersed particles. Dispersion of nanopowders into liquids is a challenging task. The high surface area and surface energy which are responsible for the beneficial effects of Nanomaterials cause agglomeration of particles...

Al2O3 Dispersion (Aluminium Oxide Dispersion)

Al2O3 DISPERSION Al2O3 Dispersion: A wide usage of metal oxide nanoparticles and nano structured materials attracts many people to research for their controlled synthesis via new method. Because, special properties of metallic or metal oxide nanoparticles exhibited several potential application in electronics, optoelectronics, catalysis and thin film coatings. In particular, alumina nanoparticles are expected to play important roles in a variety...

Quantum Dots

QUANTUM DOTS AND ITS APPLICATIONS A quantum dot gets its name because it's a tiny speck of matter so small that it's effectively concentrated into a single point (in other words, it's zero-dimensional). As a result, the particles inside it that carry electricity (electrons and holes, which are places that are missing electrons) are trapped ("constrained") and have well-defined energy levels according to the laws of quantum theory (think rungs on...

Pellet Chips Metal Balls

PELLET CHIPS METAL BALLS Pellet Chips Metal Balls: Pallets, in general, pellets have a shape known as diabolo which means that the front and rear sections are of larger diameter than the middle. One reason for this is to reduce the friction that would result if more of the pellet made contact with the barrel. Even though some air guns are rather powerful, the amount of work necessary to push the pellet down the barrel would be large if the pellet...

Metal Foils

METAL FOILS Metal Foils: A foil is a very thin sheet of metal, usually made by hammering or rolling. Foils are most easily made with malleable metals, such as aluminium, copper, tin, and gold. Foils usually bend under their own weight and can be torn easily. The more malleable a metal, the thinner foil can be made with it. Foil is commonly used in household applications. It is also useful in survival situations, because the reflective surface...
