Researchers developed a technique using single-stranded DNA to separate and sort metallic and semiconducting carbon nanotubes, enabling uniform conductivity and advancing nanoelectronic applications. The discovery in the journal Science has significant implications for developing sensitive medical diagnostic devices and mini-transistors.
Dr. Uma Chowdhry highlights emerging technologies, including biotechnology and nanotechnology, to develop new products and processes using renewable resources. DuPont has set goals to derive 25% of revenues from non-depletable resources by 2010.
DuPont scientists have developed a bio-based method using corn instead of conventional petroleum-based processes to produce the latest polymer platform. The new process uses fermentation-based production of 1,3 propanediol, which is used to create DuPont Sorona polymer with unique technical properties.
DuPont scientists have developed an innovative process for converting hydrocarbons to fluorocarbons without generating waste, producing water as a byproduct. The alternate synthesis process uses principles of inorganic chemistry to produce fluorinated aromatics in environmentally and economically efficient manners.
The article discusses the future of coatings technology, which dates back over 20,000 years, and highlights key challenges to be addressed. Dr. Robert R. Matheson Jr., a DuPont scientist, identifies issues such as reducing environmental footprint and improving biological, mechanical, and transport longevity in soft coatings.
DuPont scientists Richard Rees and W. Mark Barbour's team developed innovative technologies to minimize falling and flying glass during explosions, while also detecting harmful pathogens in food supplies with the BAX system. Their advancements strengthen global security and protection measures.
