Using high-power X-ray imaging of an actual working battery, a Stanford University-SLAC National Accelerator Laboratory team discovered that sulfur particles in the cathode largely remain intact during discharge. Their results could help scientists find new way to develop commercially viable lithium-sulfur batteries for electric vehicles.

Stanford University researchers have invented an electrically conductive hydrogel that is quick and easy to make, can be patterned onto surfaces with an inkjet printer, and demonstrates unprecedented electrical performance. This combination of characteristics hold promise for biological sensors and futuristic energy storage devices.
Stanford University scientists have breathed new life into the nickel-iron battery, a rechargeable technology developed by Thomas Edison more than a century ago. The team has created an ultrafast nickel-iron battery that can be fully charged in about 2 min and discharge in less than 30 sec.
Last week's announcement by a Stanford University team that it has created the world's first dipolar quantum ferionic gas from the metal dysprosium represents a major step toward understand the behavior of these systems of particles. And this understanding makes a leap toward the supernatural-seeming applications that condensed-matter physics conjures.
In a significant departure from earlier models, neural engineers and neuroscientists working at Stanford University have developed a new model for the brain activity underlying arm movements. Motor neurons do not represent external-world parameters as previously thought, but rather send a few basic rhythmic patterns down the spin to drive movement.
Scientists studying neutrinos have found with the highest degree of sensitivity yet that these mysterious particles behave like other elementary particles at the quantum level. The results shed light on the mass and other properties of the neutrino and prove the effectiveness of a new instrument that will yield even greater discoveries in this area.
In a new paper, Stanford University researchers describe a mathematical model they created that helps predict pragmatic reasoning and may eventually lead to the manufacture of machines that can better understand inference, context, and social rules.
Scientists from SLAC National Accelerator Laboratory, Stanford University, and Germany have figured out a key part of the industrial process for making methanol. It’s an important step toward improving the process—and eventually realizing the goal of turning a potent greenhouse gas, carbon dioxide, into fuel.
A team of engineers at Stanford University and the University of Pennsylvania has for the first time used plasmonic cloaking to create a device that can see without being seen—an invisible machine that detects light. It is the first example of what the researchers describe as a new class of devices that controls the flow of light at the nanoscale to produce both optical and electronic functions.
Some remarkable types of bacteria have proven themselves capable of "consuming" toxic pollutants, organically diminishing environmental impact in a process called bioremediation. Enzymes within these bacteria can effectively alter the molecular structure of dangerous chemicals, but the underlying mechanisms and keys to future advances often remain unknown. Now, scientists Brookhaven National Laboratory have revealed a possible explanation for the superior function of one pollution-degrading enzyme.
A multiyear collaboration among Stanford University engineering departments uses some of the world's fastest supercomputers to model the complexities of hypersonic flight. Someday, their work may lead to planes that fly at many times the speed of sound.
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds. Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford University, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma.
For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led by materials scientist has found a solution: a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.
Americans' support for government action on global warming remains high but has dropped during the past two years, according to a new survey by Stanford University researchers in collaboration with Ipsos Public Affairs. Political rhetoric and cooler-than-average weather appear to have influenced the shift, but economics doesn't appear to have played a role.
In a post-Solyndra, budget-constrained world, the transition to a decarbonized energy system faces great hurdles. Overcoming these hurdles will require smarter and more focused policies. Two Stanford writers outline their visions in a pair of analyses.

Engineers at Stanford University have found a novel method for decorating nanowires with chains of tiny particles to increase their electrical and catalytic performance. The new technique is simpler, faster, and provide greater control than earlier methods and could lead to better batteries, solar cells, and catalysts.
In a study from Stanford University and Purdue University, researchers have shown for the first time that climate change may force the U.S. corn belt to move north in the next 10 years, escaping devastating heat waves. In turn, this will bring substantial price swings to the corn market, adversely affecting industries like food and biofuels.
By depositing atoms on one side of a grid of graphene, researchers at Stanford University have engineered piezoelectricity into a nanoscale material for the first time. Twist it and it generates electricity. The implications could yield a dramatic degree of control in nanotechnology.
After five decades of debate, Stanford University engineers determine how collective electron oscillations, called plasmons, behave in individual metal particles as small as just a few nanometers in diameter. This knowledge may open up new avenues in nanotechnology ranging from solar catalysis to biomedical therapeutics.
Using a sophisticated weather model, environmental engineers at Stanford University have defined optimal placement of a grid of four wind farms off the United States East Coast. The model successfully balances production at times of peak demand and significantly reduces costly spikes and zero-power events.
Researchers from Stanford University and the SLAC National Accelerator Laboratory have created the first-ever system of "designer electrons"—exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices.
As cities and towns rebuild after last year's devastating tsunami and earthquake in northeastern Japan, there is a potentially huge demand for the green technology and new information technology now being created in laboratories at Stanford University and start ups across Silicon Valley.
An international team of scientists with roots at SLAC National Accelerator Laboratory and Stanford University has shown that ultrathin sheets of an exotic material, called topological insulators, remain transparent and highly conductive even after being deeply flexed 1,000 times and folded and creased like a piece of paper.
