In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber’s energy gap, transferring just a small portion of light energy into electricity. The remaining energy is lost as heat. But in a paper released May 13 in Science Advances, Wu, UW associate professor Xiaodong Xu and colleagues at four other institutions describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.

Four faculty members at the University of Washington have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 23, include Bingni Brunton, assistant professor of biology; Christopher Laumann, assistant professor of physics; Matthew McQuinn, assistant professor of astronomy; and Emina Torlak, assistant professor of computer science and engineering….

University of Washington scientists have successfully combined two different ultrathin semiconductors — each just one layer of atoms thick and roughly 100,000 times thinner than a human hair — to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics.

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos.

A team of scientists at the University of Washington and the biotechnology company Illumina have created an innovative tool to directly detect the delicate, single-molecule interactions between DNA and enzymatic proteins. Their approach provides a new platform to view and record these nanoscale interactions in real time. As they report Sept. 28 in Nature Biotechnology, this tool should provide fast and reliable characterization of the different mechanisms cellular proteins use to bind to DNA strands — information that could shed new light on the atomic-scale interactions within our cells and help design new drug therapies against pathogens by targeting enzymes that interact with DNA.

The Fermi National Accelerator Laboratory — or Fermilab — announced that a 680-ton superconducting magnet is secure in its new home and nearly ready for a new era of discovery in particle physics. This achievement follows the delicate, 3,200-mile transport of the magnet’s 17-ton, 50-foot-wide housing ring to the U.S. Department of Energy facility outside Chicago two years ago. The fully assembled magnet will drive high-energy particle experiments as part of an international partnership among 34 institutions, of which the University of Washington is a leading contributor.

The Large Hadron Collider has started recording data from the highest-energy particle collisions ever achieved on Earth. This new data, the first recorded since 2012, will enable an international collaboration of researchers — including many from the UW — to study the Higgs boson, search for dark matter and develop a more complete understanding of the laws of nature.

UW physicists have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery electrodes and air filters — key information for improving those technologies.

UW researchers and their collaborators used an experiment in the physics building to measure the energy of a single electron emitted by radioactive decay, a key step in their strategy to measure the mass of the elusive neutrino.

University of Washington scientists have built a new nanometer-sized laser using a semiconductor that’s only three atoms thick. It could help open the door to next-generation computing that uses light, rather than electrons, to transfer information.

University of Washington engineers have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output.

Scientists have developed what they believe is the thinnest-possible semiconductor, a new class of nanoscale materials made in sheets only three atoms thick.
March 10, 2014
University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics. The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

The same physics that gives stability to tornadoes lies at the heart of new UW research and could lead to a better understanding of nuclear dynamics in studying fission, superconductors and the workings of neutron stars.

New research indicates that a phenomenon called “quantum entanglement” could be intrinsically linked with the creation of wormholes.

Physicists are using a detector at the UW to search for a particle called an axion, which would be the first physical evidence of the universe’s dark matter.
