UC Irvine researchers are leading the effort to understand the causes and effects of one of the worlds leading environmental problems -- air pollution. They are studying both regional and worldwide air pollution issues, ranging from the effects of freeway exhaust to the role dust storms and forest fires may play. UCI is also involved in a large-scale commuter transportation project designed to cut back on auto emissions and is home to the Air Pollution Health Effects Laboratory, which continues to increase understanding of the risks air carcinogens present to children. Here are a few current research projects of note.
Large Scale Forest Fires Also Raise Ozone Pollutant Levels
The product of the large-scale forest fires that have plagued the Western United States is easy to see -- thick, dark smoke filling the skies. But downwind, gaseous emissions from fires create a pollutant invisible to the eye, but no less dangerous - ozone. Atmospheric chemist Donald Blake, who studies the impact of biomass burning on the atmosphere, says that when sunlight combines with nitrogen oxides and hydrocarbons in the smoke, resulting chemical reactions form ozone, and lots of it. These enhanced concentrations of ozone can blow around for several weeks, Blake adds. The result is air quality downwind from fires that can reach hazardous levels. Ozones effect on humans can range from eye irritation to worsening existing lung conditions such as asthma.

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...
