 Ruthenium (Ru) Nanoparticles, nanodots or nanopowder are brown spherical high surface area metal particles. Nanoscale Ruthenium Particles are typically 20 - 100 nanometers (nm) with specific surface area (SSA) in the 1 - 3 m 2 /g range. Nano Ruthenium 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 Ruthenium nanocrystals include for use in electrochemical capacitors, in a nucleation layer of palladium and ruthenium nanoparticles in-between the copper pad surface to create an electrical connection that has superior diffusion barrier and adhesion properties , as a hydrogenation catalyst and numerous other uses in catalysts, in polymer membranes to create Active Polymer Membranes and in other coatings, plastics, nanofiber and textiles and in nanowire and other catalysis applications. Ruthenium Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
 Ruthenium is a Block D, Group 8, Period 5 element. The number of electrons in each of Ruthenium's shells is 2, 8, 18, 15, 1 and its electronic configuration is [Kr] 4d7 5s1. In its elemental form ruthenium's CAS number is 7440-18-8. The ruthenium atom has a radius of 132.5.pm and it's Van der Waals radius is 200.pm. Ruthenium tetroxide (RuO4) is very toxic and Ruthenium in its elemental form is considered carcinogen. Ruthenium is member of the platinum group of metals. It is one of the most effective hardeners for platinum and palladium , and is alloyed with these metals to make electrical contacts for severe wear resistanant  electronics and laboratory equipment. The corrosion resistance of titanium is improved a hundredfold by addition of 0.1% ruthenium. It is also a versatile catalyst. Hydrogen sulfide can be split catalytically by light using an aqueous suspension of cadmium sulfide particles loaded with ruthenium dioxide. It is also believed to have pharmacological applications. Ruthenium 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. Ruthenium was first discovered by Karl Klaus in 1844. The name Ruthenium, originates from the Latin word 'Ruthenia' meaning Russia. See Ruthenium research below. |
