Coming to a monitor near you: A defect-free, molecule-thick film


An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale ...


Artificial 'plants' could fuel the future


Imagine creating artificial plants that make gasoline and natural gas using only sunlight. And imagine using those fuels to heat our homes or run our cars without adding any greenhouse gases to the atmosphere. By combining nanoscience and biology, researchers led by scientists at University of ...


CT scan of Earth links deep mantle plumes with volcanic hotspots

Scans prove that plumes of hot rock anchored at core-mantle boundary rise to form island chains


Seismologists have produced for the first time a sharp, three-dimensional scan of Earth's interior that conclusively connects plumes of hot rock rising through the mantle with surface hotspots that generate volcanic island chains like Hawaii, Samoa and Iceland. Essentially a computed tomography, ...

Major innovation in molecular imaging delivers spatial and spectral info simultaneously

Berkeley Lab scientist invents technique to combine spectroscopy with super-resolution microscopy


Using physical chemistry methods to look at biology at the nanoscale, a Lawrence Berkeley National Laboratory (Berkeley Lab) researcher has invented a new technology to image single molecules with unprecedented spectral and spatial resolution, thus leading to the first "true-color" ...


World's quietest gas lets physicists hear faint quantum effects

Lowest-entropy gas allows modeling of quantum systems such as high-temperature superconductors


Physicists at the University of California, Berkeley, have cooled a gas to the quietest state ever achieved, hoping to detect faint quantum effects lost in the din of colder but noisier fluids. While the ultracold gas's temperature - a billionth of a degree above absolute zero - is twice as hot ...

Major advance in artificial photosynthesis poses win/win for the environment

Berkeley Lab researchers perform solar-powered green chemistry with captured CO2


A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical ...


Study reveals how oxygen is like kryptonite to titanium

Discovery could lead to cost-effective use of cheaper grades of popular material


Scientists at the University of California, Berkeley, have found the mechanism by which titanium, prized for its high strength-to-weight ratio and natural resistance to corrosion, becomes brittle with just a few extra atoms of oxygen. The discovery, described in Science, has the potential to open ...

Scientists set quantum speed limit

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 ...

Scientists measure speedy electrons in silicon

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 ...


Tiny laser sensor heightens bomb detection sensitivity


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 ...
