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...

Porous proppant for delivering bacteria

Invention SummaryU-6110 is a proppant – a solid material designed to keep hydraulic fractures open during mining – for use in fracking. Fracking is a process of mining for natural fuel resources that is done by creating fissures in the earth and then pumping proppant in to hold the fissures open before they are closed due to geological...

Thermoelectric Energy Harvester

Invention SummaryThermoelectric (TE) power generation is considered one of the most promising clean energy conversion technologies. It harvests energy from waste or natural heat without producing any direct emissions of greenhouse gases over its life time. U-6170 transforms a temperature difference into electrical power without moving parts. The material...

Laminable Electrochromic Coatings

Invention SummaryA novel method to manufacture electrochromic windows for increasing energy efficiency is under development at the University of Utah. In modern residential and commercial buildings, the most significant contributor to high heating and cooling loads is the poor energy efficiency of windows. Windows will always be inherently less effective...

Experimental Procedure for CdTe deposition

Invention SummaryThe invention is a new method for producing cadmium telluride (CdTe) thin films using a direct conversion process from aqueous precursors of cadmium and tellurium ions. The process is carried out at room temperature with atmospheric pressure using a spin coater by alternately depositing the cadmium and tellurium precursor solutions...

Novel method for pi-pi stacking of polycyclic aromatic molecules for organic-based electronic materials

Invention SummaryA novel method of creating stacked polycyclic aromatic hydrocarbons (PAH) has been determined using powerful quantum mechanical calculations. This can be used in order to develop tune-able bandgaps that can be used in OLEDs (organic light emitting diodes), solar cells, flexible displays, and new types of semiconductors/transistors....

Two-Phase Functionally Graded Tantalum Carbide

Invention SummaryHard materials resist wear, but are more prone to fracture. Tough materials resist fracture, but are more susceptible to wear. Generally, it is difficult to design a material that is both hard and tough. This invention seeks to balance these considerations by providing a two-phase material that exhibits both high hardness and high fracture...

Pressure-less Method for Binding Tantalum Carbides

Invention SummaryThis technology is a novel and low-cost method for binding tantalum carbides. This method is known as pressure-less sintering and only requires certain levels of heat to bond tantalum carbides. Most existing methods require both heat and pressure, necessitating more elaborate manufacturing processes. Currently, this method is used...

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...

An Improved Milling Method for the Production of Nanoparticles From Soft Metals

Invention Summary This novel milling method allows rapid production of multi-gram quantities of nanoparticles of soft or ductile metals with controlled and narrow size distributions. The nanoparticles can optionally be coated with a capping agent that controls solubility/dispersibility in various media including polar and non-polar organic solvents,...
