'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.

AGU Talk: Scaling Climate Change Communication for Behavior Change
In a previous randomized controlled trial, Stanford University researchers developed two curricula for Girl Scouts to use energy more efficiently: one on energy use at home, and the other in transportation and food. Both courses were effective for girls in the short term, and the home energy course was effective for girls in the long term and for parents in the short term.

Global Warming's Influence on Extreme Weather
Extreme climate and weather events such as record high temperatures, intense downpours and severe storm surges are becoming more common in many parts of the world. But because high-quality weather records go back only about 100 years, most scientists have been reluctant to say if global warming affected particular extreme events.

Avoiding Ecosystem Collapse
From coral reefs to prairie grasslands, some of the world's most iconic habitats are susceptible to sudden collapse due to seemingly minor events. A classic example: the decimation of kelp forests when a decline of otter predation unleashes urchin population explosions. Three studies published in the Nov. 24 special issue of Philosophical Transactions of the Royal Society Biological Science hold the promise of helping resource managers predict, avoid, and reverse the tipping points that lead to degraded habitats, economic losses, and social upheaval.…

Using Science to Open Way to 'Blue Economy'
STANFORD, CA Today, scientists at the Natural Capital Project share new science and open source software that can calculate risk to coastal and marine ecosystems. These novel tools, described in the journal Environmental Research Letters, were used to design the first integrated coastal zone management plan for the Caribbean country of Belize.

Stanford Biologists Explore Link Between Memory Deficit And Misfiring Circadian Clock
Anyone who has struggled with a foggy brain while adjusting to daylight saving time knows first-hand how an out-of-sync circadian clock can impair brain function. Now, by manipulating the circadian clocks of Siberian hamsters, Stanford scientists may have identified a brain structure that disrupts memory when circadian rhythms fall apart, as they often do in patients with neurodegenerative diseases such as Alzheimer's.

Stanford Scientists Create a 'Smart' Lithium-ion Battery That Warns of Fire Hazard
Stanford University scientists have developed a "smart" lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.
