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.
Researchers working at SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules—a mechanism that has baffled organic chemists for decades.
It's one thing to design and build a brand-new piece of technology, to test it and tune it until it works just right. It's an entirely different matter to take that one-of-a-kind instrument and mass produce it. But that's essentially what the fabrication team for the Cryogenic Dark Matter Search did.
For 50 years, scientists searched for the secret to making tiny implantable devices that could travel through the bloodstream. Engineers at Stanford University have demonstrated such a device. Powered without wires or batteries, it can propel itself through the bloodstream and is small enough to fit through blood vessels.
The United States Air Force Office of Scientific Research has awarded $8.5 million to a consortium of seven U.S. universities that will work together to determine the best approach for generating quantum memories based on interaction between light and matter. The team will consider three different approaches for creating entangled quantum memories that could facilitate the long-distance transmission of secure information.
Obama's new rule is only one step toward ensuring the safety of hydraulic fracturing, the booming technology that offers economic and environmental benefits, according to Stanford University geophysicist and DOE adviser Mark Zoback.
At the nano level, researchers at Stanford University have discovered a new way to weld together meshes of tiny wires. The technique harness plasmonics to fuse wires with a simple blast of light. Their work could lead to innovative electronics and solar applications.
A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.
Every year, students studying aeronautical and astronautical design brace themselves for the time-consuming process of writing their own code to optimize aerospace designs. In search of a better way, a team of engineers at the Aerospace Design Lab at Stanford University has released SU2, an open-source application that models the effects of fluids moving over aerodynamic surfaces.
A big reason for publishing scientific results is to inform others who can then use your data and conclusions to make additional discoveries, technologies or products. But what good are findings if they are, well, hard to find? Scientists from the SLAC National Accelerator Laboratory and Stanford University have a solution for those who design new chemical catalysts: They made an app.
Organic semiconductors could usher in a new era of electronics. But there is one serious drawback: Organic semiconductors do not conduct electricity very well. However, researchers at Stanford University have changed that equation by improving the ability of the electrons to move through organic semiconductors.
While it is possible to chemically scrub carbon dioxide from Earth's atmosphere in order to lessen the severity of global warming, the process is prohibitively expensive for now. Best to focus on controls for coal-burning power plants, say researchers from Stanford University and the Massachusetts Institute of Technology.
Since most of the world's governments have not yet enacted regulations to curb emissions of greenhouse gases, some experts have advocated the development of technologies to remove carbon dioxide directly from the air. But a new Massachusetts Institute of Technology study shows that, at least for the foreseeable future, such proposals are not realistic because their costs would vastly exceed those of blocking emissions right at the source, such as at the powerplants that burn fossil fuels.
Stanford University researchers are proposing to use opal to sequester uranium at contaminated sites. The idea springs from natural deposits of opal, containing uranium, that have been stable for hundreds of thousands or even millions of years.
