Silicon Nanorods are elongated particles ranging from 10 to 120 nanometers (nm) with specific surface area (SSA) in the 30 - 70 m 2 /g range. Nano Silicon is also available passivated and in Ultra high purity and high purity and coated and dispersed forms. They are also available as a nanofluid through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanorods in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanoparticles, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Surface functionalized nanorods allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers , Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots . High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil. Applications for Silicon nanorods generally involve their magnetic properties and include in catalysts and magnetic recording and in medical sensors and bio medicine as a contrast enhancement agent for magnetic resonance imaging (MRI). Silicon particles are being tested for site specific drug delivery agents for cancer therapies and in coatings, plastics, nanowire, nanofiber and textiles and in certain alloy and catalyst applications . Further research is being done for their potential electrical, dielectric, magnetic, optical, imaging, catalytic, biomedical and bioscience properties. Silicon Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
Silicon is a Block P, Group 14, Period 3 element. The electronic configuration is [Ne] 3s2 3p2. In its elemental form silicon's CAS number is 7440-21-3. The silicon atom has a radius of 117.6.pm and it's Van der Waals radius is 210.pm. Silicon is one of man's most useful elements. It makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, being exceeded only by oxygen. The Czochralski process is commonly used to produce single crystals of silicon used for solid-state or semiconductor devices. Silica, as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. Silicon is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Ultra high purity silicon can be doped with boron, gallium, phosphorus , or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics and space-age industries. Hydrogenated amorphous silicon has shown promise in producing economical cells for converting solar energy into electricity. Silcones are important products of silicon. They range from liquids to hard, glasslike solids with many useful properties.
