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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
