This research focuses on an innovative materials technology that allows the entrapment of biocidal organic compounds in biocidal silver resulting in the formation of a powerful antibacterial composite called SilverPlus.
In the quest for alternative energy sources and eco-friendly technological processes there is a growing need for photocatalysts that are able to utilize visible light. Researchers have developed a new family of photocatalysts that are more effective at removing water pollutants abd a patrent application has been filed.
Silicon substrates for solar cell applications must meet exacting technical requirements. Adding surface texture increases light-gathering efficiency, but too much texture scatters light away and reduces efficiency. The Zeta-200 automated 3D metrology system allows quality control of critical properties.
Inexpensive chemical technologies are well positioned to compete in the renewables markets, particularly as petrochemical margins are squeezed by the rising cost and declining availability of oil.
