Stanford scientists create novel silicon electrodes that improve lithium-ion batteries
06-06-2013
Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products. Writing in the edition of the ...
Stanford ultraresponsive magnetic nanoscavengers for next generation water purification
New synthetic cored nanoparticle could decontaminate tainted water and then be cleared with a magnet
17-05-2013
Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Yet other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using ...
A membrane-free lithium/polysulfide semi-liquid battery for large-scale energy storage
07-05-2013
Scientists in the US have developed a new lithium/polysulfide (Li/PS) semi-liquid battery for large-scale energy storage, with lithium polysulfide (Li2S8) in ether solvent as a catholyte and metallic lithium as an anode. As the catholyte is designed to cycle only in the range between sulfur ...
X-ray laser reveals chemical reaction
18-03-2013
What happens when a chemical bond is broken? That question was recently answered with the help of a so-called free electron x-ray laser, which makes it possible to follow in real time how bindings in a molecule are changed and broken. The study, published in Science, found, among other ...
Stanford researchers map out an alternative energy future for New York
13-03-2013
New York Gov. Andrew Cuomo will soon decide whether to approve hydraulic fracturing for natural gas in the state. To date, no alternative to expanded gas drilling has been proposed. But a new study finds that it is technically and economically feasible to convert New York's all-purpose energy ...
2012 Nobel Prize in Chemistry Uses Research Equipment Engineered Locally from BMG LABTECH
16-10-2012
Robert J. Lefkowitz from Duke University, along with Brian Kobilka from Stanford University, were just awarded the 2012 Nobel Prize in Chemistry for their research and discovery of the receptor protein that binds to adrenaline, that is the beta-adrenergic receptor. A receptor protein crosses ...
Stanford-SLAC team uses X-ray imaging to observe running batteries in action
20-07-2012
Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries – a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more ...
Stanford researchers use river water and salty ocean water to generate electricity
11-04-2011
Stanford researchers have developed a battery that takes advantage of the difference in salinity between freshwater and seawater to produce electricity. Anywhere freshwater enters the sea, such as river mouths or estuaries, could be potential sites for a power plant using such a battery, ...
High-temperature superconductor spills secret: A new phase of matter
28-03-2011
Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these ...
Purdue-Stanford team finds radioactive decay rates vary with the sun's rotation
01-09-2010
Radioactive decay rates, thought to be unique physical constants and counted on in such fields as medicine and anthropology, may be more variable than once thought. A team of scientists from Purdue and Stanford universities has found that the decay of radioactive isotopes fluctuates in synch ...
