Findings may lead to more effective regulations for protecting public health
Using data from one of the most comprehensive U.S. air pollution studies ever conducted, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have identified specific volatile organic compounds (VOCs) as key sources of excess ozone smog in industrial areas of Houston, Texas -- which appear to be different from traditional sources of ozone pollution in typical urban areas around the country. Specific efforts to control these industrial emissions of VOCs might be necessary to control Houston’s ozone problem, say the authors, whose findings will appear in an upcoming issue of Geophysical Research Letters (published on-line May 28, 2002).
"A clear understanding of the complex causes of ozone pollution will help to identify cost-effective ways to control smog and protect public health," said atmospheric chemist Larry Kleinman, one of the lead Brookhaven researchers on the study.
This work was funded by the U.S. Department of Energy, which supports basic research in a variety of scientific fields; the U.S. Environmental Protection Agency; and the Texas Natural Resource Conservation Commission.

The U.S. Department of Energy’s Brookhaven National Laboratory (http://www.bnl.gov) conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies. Brookhaven also builds and operates major facilities available to university, industrial, and government scientists. The Laboratory is managed by Brookhaven Science Associates, a limited liability company founded by Stony Brook University and Battelle, a nonprofit applied science and technology organization.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...

Scientists at Helmholtz Zentrum München have discovered a mechanism that amplifies the autoimmune reaction in an early stage of pancreatic islet autoimmunity prior to the progression to clinical type 1 diabetes. If the researchers blocked the corresponding molecules, the immune system was significantly less active. The study was conducted under the auspices of the German Center for Diabetes Research (DZD) and was published in the journal ‘Science Translational Medicine’.
Type 1 diabetes is the most common metabolic disease in childhood and adolescence. In this disease, the body's own immune system attacks and destroys the...
