Higher quality quantum dots for LED screens that use much less toxic feedstock. This technology replaces the traditional centrifugation method with filtration and uses less toxic solvents. Conventional methods of producing LED screens make substantial use of toxic solvents and are inefficient. This new technology could potentially reduce the use of toxic solvents by 150,000 liters per year in the United States. This technology is also more efficient, reducing energy usage. 

Uses water and oxygen to remove photoresist and other organic contaminants in producing semiconductors and flat panel displays. Coldstrip™ uses a gas diffuser and an ozone generator. This process cleans more quickly than many chemical-based processes as it produces no solids in the water (eliminating the need for filtration) and does not require elevated temperatures. Traditionally, Piranha solutions (containing sulfuric acid and hydrogen peroxide) are used to produce semiconductors and flat panel displays.
