Proof of energy time uncertainty principle puts limits on quantum computing
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to optical switching.The energy-time uncertainty relationship is the flip side of the ...
Attosecond laser provides first 'movie' of fast electrons jumping band-gap of semiconductor
The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our ...
New technology under development at the University of California, Berkeley, could soon give bomb-sniffing dogs some serious competition. A team of researchers led by Xiang Zhang, UC Berkeley professor of mechanical engineering, has found a way to dramatically increase the sensitivity of a ...
Teaming together with universities on the West Coast, BASF Corporation has set up a multidisciplinary research institute with an emphasis on new inorganic materials and their applications, biosciences, and related technologies. The California Research Alliance by BASF (CARA) will bring together ...
Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors ...
Interactive maps of US metro areas shows striking differences between cities and suburbs
According to a new study by researchers at the University of California, Berkeley, population-dense cities contribute less greenhouse gas emissions per person than other areas of the country, but these cities' extensive suburbs essentially wipe out the climate benefits. Dominated by emissions ...
Scientists introduce a general theoretical approach that describes all known forms of high-temperature superconductivity and their "intertwined" phases
Years of experiments on various types of high-temperature (high-Tc) superconductors—materials that offer hope for energy-saving applications such as zero-loss electrical power lines—have turned up an amazing array of complex behaviors among the electrons that in some instances pair up to carry ...
Nearly every body of water, from a puddle or a pond to a vast ocean, contains microscopic organisms that live attached to rocks, plants, and animals. These so-called sessile suspension feeders are critical to aquatic ecosystems and play an important role in cleaning up environmental contaminants ...
Gems for new technology
A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers – defects in which two adjacent carbon atoms in the diamond's crystal structure are replaced ...
Berkeley Lab and UC Berkeley researchers develop method for predicting adsorption in carbon dioxide-scrubbing materials
Scientists would like to apply the same principles by which baking soda removes food odors from refrigerators or silica powder keeps moisture away from electronic devices to scrub carbon dioxide from the exhaust gases of fossil fuel power plants. An excellent candidate for this task is the class ...
