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

Published: May 28, 2012.
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.

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.
Causes of California Drought Linked to Climate Change
The atmospheric conditions associated with the unprecedented drought currently afflicting California are "very likely" linked to human-caused climate change, Stanford scientists say.
