'Unzipped' Carbon Nanotubes Could Help Energize Fuel Cells And Batteries, Stanford Scientists Say

Published: May 28, 2012.
Released by Stanford University  

Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at Stanford University. Their findings are published in the May 27 online edition of the journal Nature Nanotechnology.

Stanford Scientists Help Discover Pacific Bluefin Tunas' Favorite Feeding Spots
After chowing down a big meal, you might feel your belly warm as your stomach muscles and digestive organs set to work breaking your food into smaller and smaller pieces rich in nutrients. A bluefin tuna's stomach experiences a similar spike in temperature when it gulps down a mouthful of juicy sardines.

Stanford Team Re-engineers Virus to Deliver Therapies to Cells
Stanford researchers have ripped the guts out of a virus and totally redesigned its core to repurpose its infectious capabilities into a safe vehicle for delivering vaccines and therapies directly where they are needed. The study reported today in the Proceedings of the National Academy of Sciences breathes new life into the field of targeted delivery, the ongoing effort to fashion treatments that affect diseased areas but leave healthy tissue alone.

Stanford Engineers Develop a Wireless, Implantable Device to Stimulate Nerves in Mice
A miniature device that combines optogenetics - using light to control the activity of the brain - with a newly developed technique for wirelessly powering implanted devices is the first fully internal method of delivering optogenetics.

Single-catalyst Water Splitter Produces Clean-burning Hydrogen 24/7
Stanford University scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hours a day, seven days a week. The device, described in a study published June 23 in Nature Communications, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.

New Research Initiative at Stanford to Comprehensively Study the Use of Natural Gas
In the transition to a low-carbon energy system, how can society use increasing supplies of natural gas to minimize greenhouse gas emissions, improve air quality, boost economies and strengthen energy security? Stanford University's new Natural Gas Initiative will work to answer that question, as well as myriad scientific, technological and policy questions that underlie it.

Stanford Scientists Show FMRI Memory Detectors Can Be Easily Fooled
For the past several years, Anthony Wagner has been developing a computer program that can read a person's brain scan data and surmise, with a high degree of certainty, whether that person is experiencing a memory. The technology has great promise to influence a number of fields, including marketing, medicine and evaluation of eyewitness testimony.

Stanford Engineers Develop State-by-state Plan to Convert US to 100% Renewable Energy
One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs and stabilize energy prices involves converting the world's entire energy infrastructure to run on clean, renewable energy.

Just Add Water: Stanford Engineers Develop a Computer That Operates on Water Droplets
Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets.
