About Selenium Nanoparticles

High Purity, D50 = +10 nanometer (nm) by SEMSelenium nanoparticles, nanodots or nanopowder are typically 10 - 45 nanometers (nm) with specific surface area (SSA) in the 30 - 50 m2/g range and also available in with an average particle size of 75 - 100 nm range with a specific surface area of approximately 2 - 10 m2/g. Nano Selenium Particles are also available in passivated and Ultra high purity and high purity and coated and dispersed forms. They are also available as a dispersion through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Gold Nanoparticles and Carbon Nanoparticles have found novel application in cancer treatment using radio waves to heat and destroy a tumor, lymphoma, or metastasized cancer. Recent discoveries confirm the feasibility of this technology in humans. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers.

Selenium Bohr ModelSee more Selenium products. Selenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure three red-colored forms with monoclinic crystal structures and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. Elemental SeleniumOne of the mose common uses for selenium is in glass production the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.
