System speeds identification of workplace chemicals
Article Abstract:
Researchers at Pacific Northwest National Laboratory developed the Exposure-to-Risk Monitoring System for the immediate measurement of chemicals that workers may have ingested, absorbed or inhaled. The system uses a pharmacokinetic model to translate exposure levels into the amount of internal dose received. It has a mouthpiece where workers suspected of being exposed to a chemical can breath for one or two minutes. A mass spectrometer is used in analyzing the breath sample for volatic organic compounds up to less than 10 ppb.

Micropassages cool microchips
Article Abstract:
A novel substrate that removes heat from microchips and printed circuit boards have been developed by researchers at Sandia National Laboratory. The experimental substrate remove hot spots from these semiconductor devices and can possibly increase the reliability and life span of computers, photovoltaic cells and communications satellites. The substrate is made up of microscopic heat pipes built directly within the substrate material to carry heat away from the chip more efficiently than heat conduction through solid copper.

Nanocomposite coating mimics seashells
Article Abstract:
Researchers at Sandia National Laboratories and the University of Mexico have developed a new process for creating materials into coatings that mimic seashell structures. The novel process allows for the rapid formation of strong and transparent coatings that can be used as automotive finishes and coatings for optical lenses. It is based on the tendency of two-sided molecules to form micelles spontaneously.
