P-MITE™ powders and dispersions are Platinum (Pt) nanoparticles, nanodots or nanopowder. Nanoscale Platinum Particles are typically 10 - 100 nanometers (nm) with specific surface area (SSA) up to 45 m 2 /g. These nanospheres are ideal candidates as a novel technology for low platinum automotive catalysts and for single-nanotechnology research. Nano Platinum Particles are also available 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 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. Surface functionalized nanoparticles 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 Platinum nanocrystals include numerous uses in catalysts (including catalytic converters), electrocatalysts, chemical synthesis (also in silver-platinum nanoparticles) and as a Magnetic Nanopowder (also in iron-platinum nanoparticles) and deposed on silica and carbon nanotubes, in polymer membranes to create Active Polymer Membranes for Proton Exchange Membrane (PEM) fuel cells and in other coatings, plastics, nanofiber and textiles and in nanowire and other catalysis applications. Platinum Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.

Platinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f¹⁴ 5d⁹ 6s¹. In its elemental form platinum's CAS number is 7440-06-4. The platinum atom has a radius of 137.3.pm and its Van derWaals radius is 172.pm. Though it is one of the rarer and more expensive metals used in manufacturing, a highly efficient electrodeposition process unique to Platinum discovered by the National Institute of Standards and Technology (NIST) in December 2012 may lower the industrial costs of Platinum ultrathin films in the future. Platinum is not toxic. Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane fuel cells. The metal does not oxidize in air at any temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Platinum is found in alluvial deposits and with iridium as platiniridium. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below.
