'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 Use Ocean Waves to Monitor Offshore Oil And Gas Fields
A technology developed by Stanford scientists for passively probing the seafloor using weak seismic waves generated by the ocean could revolutionize offshore oil and natural gas extraction by providing real-time monitoring of the subsurface while lessening the impact on marine life.

Perovskites Provide Big Boost to Silicon Solar Cells, Stanford Study Finds
Stacking perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford University scientists. The researchers describe their novel perovskite-silicon solar cell in this week's edition of the journal Energy & Environmental Science.

Stanford-led Study Says China's Aquaculture Sector Can Tip the Balance in World Fish Supplies
In a new paper in Science a research team led by Stanford postdoctoral scholar Ling Cao and Professor Rosamond Naylor offers the clearest picture to date of China's enormous impact on wild fisheries. The study also presents a more sustainable alternative to the current practice of using wild-caught fish to feed farm-raised fish.

Estimated Social Cost of Climate Change Not Accurate, Stanford Scientists Say
The economic damage caused by a ton of carbon dioxide emissions - often referred to as the "social cost" of carbon - could actually be six times higher than the value that the United States now uses to guide current energy regulations, and possibly future mitigation policies, Stanford scientists say.

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.
