Invention SummaryTitanium has exceptional properties such as high strength, light weight, superior corrosion resistance, and the best biocompatibility of any metal. Unfortunately, titanium is not widely used today since the cost is about 20 times that of general purpose steel. There has been a large amount of research in the past fifty years in search...

Thermal Energy Battery with Low Cost and High Heating and Cooling Powers

Invention SummaryWe have developed technology that can replace traditional Auxiliary Power Units (APU) in semi-trucks which removes their need to idle. This technology is a chemical thermal energy battery that can store and subsequently release the energy in a controlled fashion when and where it is needed. The technology uses the long haul truck’s...

Direct Production of Titanium Dioxide from Ilmenite

Invention Summary Titanium dioxide is the most abundantly produced inorganic pigment in the world. It is predominantly produced by the chloride process, which employs carbo-chlorination and oxidation of titanium feed stocks at high temperature (~1300 to 1800º C). It is an energy intensive process and directly emits 550 kg CO2/ton TiO2 . A more energy...

Thermal Degradation and Crack Resistant Functionally Graded Cemented Tungsten Carbide and Polycrystalline Diamond for Metal Machining and Rock Drilling Tools **Value Express**

Patent Abstract A WC—Co material or polycrystalline diamond-Co material that has a gradient in the grain size of the particles. Specifically, the material may have a top layer that has coarse grains that is designed to dissipate the heat caused by friction (and thus prevent thermal cracking). The material will then have a bulk substrate that is...
