In an economy with soaring raw material and rising heat-transfer-fluid prices, fluid manufacturers are getting more requests for high-performance products that will do the required job for a longer time period. As a result, fluid manufacturers are working to develop new products with advanced chemistries and boost service programs in an effort to help customers lower their costs and extend the life of the...

Engineers at MIT (Cambridge, Mass.; www.mit.edu) are developing solar concentrators that have the potential to increase the electrical power output from solar cells by a factor of more than 40. Instead of actually focusing the light, as in systems being developed elsewhere (see also below), MIT’s device makes use of a coating of two or more dyes on the surface of a pane of glass or plastic, with...

Optoacoustic gas detection determines gas content via the measurement of acoustic pressure waves that are propagated as a gas is irradiated under an appropriately tuned light. A gaseous-mixture sample passes through a membrane into a measurement cell, which contains an infrared light source and a microphone. Incident light modulated at a specific frequency is briefly absorbed as intermolecular energy by...

The production of hydrogen by water splitting promises to become less expensive through a solar-energy process being developed at Penn State University (University Park, Pa.; www.psu.edu). Like other photoelectrochemical methods, the process splits water into its two components, generating O2 at the anode and H2 at the cathode. However, the configuration of the system is different. Developed by Craig...

Corn residue left in fermenters after ethanol production could find a future use as a filler in plastics through research being done at the U.S. Dept. of Agriculture’s North Central Agricultural Research Laboratory (Brookings, S.D.; www.ars.usda.gov). The granular residue, called distiller’s dried grains (DDGs), is now used mainly for animal feed. Plastics would provide an additional market...

  Much as the chemical process industries (CPI) themselves are always evolving, so too are the engineering materials that play a role behind the scenes. While they may not always make headlines as groundbreaking scientific technologies tend to do, new and improved engineering materials are constantly emerging to enhance and advance the practice of chemistry. A few of the latest materials are...
