Proton Transfer in Ionized Dimethyluracil
A Surprising New Kind of Proton Transfer
Mar 19, 2012 07:10 AM E
When a proton - the bare nucleus of a hydrogen atom - transfers from one molecule to another, or moves within a molecule, the result is a hydrogen bond, in which the proton and another atom like nitrogen or oxygen share electrons. Conventional wisdom has it that proton transfers can only happen using hydrogen bonds as conduits, "proton wires&q...

New Test Finds Neutrinos didn't Beat Light Barrier
Mar 16, 2012 12:33 PM E
New research suggests neutrinos that appeared to break a basic law of physics by travelling faster than the speed of light kept within the universal speed limit after all.
Fighting Cancer with Nanotechnology
Mar 16, 2012 07:27 AM E
Imagine a test that sifts through millions of molecules in a drop of a patient's blood to detect a telltale protein signature of a cancer subtype, or a drug ferry that doesn't release its toxic contents until it slips inside cancer cells.
Researchers Develop Graphene Supercapacitor Holding Promise for Portable Electronics
Mar 15, 2012 16:12 PM E
Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially higher amounts of charges. They have garnered attention as energy storage devices as they charge and discharge faster than batteries, yet they are still limite...

Researchers Create More Efficient Hydrogen Fuel cells
Mar 15, 2012 11:32 AM E
Hydrogen fuel cells, like those found in some "green" vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective.
A Swell Electrode
Silicon-carbon Electrodes Snap, Swell, Don't Pop
Mar 15, 2012 08:52 AM E
A study that examines a new type of silicon-carbon nanocomposite electrode reveals details of how they function and how repeated use could wear them down. The study also provides clues to why this material performs better than silicon alone. With an electrical capacity five times higher than conventional lithium battery electrodes, silicon-carbon n...

Researchers Send 'Wireless' Message Using Elusive Particles
Mar 14, 2012 15:56 PM E
A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos - nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, "Neutrino.
Suspended Graphene Device
Barrier to Faster Graphene Devices Identified and Suppressed
Mar 13, 2012 17:03 PM E
These days graphene is the rock star of materials science, but it has an Achilles heel: It is exceptionally sensitive to its electrical environment. This single-atom-thick honeycomb of carbon atoms is lighter than aluminum, stronger than steel and conducts heat and electricity better than copper.

DuPont Joins Stanford's Global Climate and Energy Project
Mar 12, 2012 16:47 PM E
DuPont has joined the Global Climate and Energy Project (GCEP) at Stanford University, an industry partnership that supports innovative research on sustainable energy technologies with low greenhouse gas emissions.
Fractal Silver Trees
Tiny Fractal Trees for Solar Power
Mar 12, 2012 13:10 PM E
Microscopic "fractal trees" grown from silver could be the basis of a new type of solar cell, say chemists at the University of California, Davis. "We expect these structures will allow us to make better, more efficient solar cells," said Professor Frank Osterloh, a principal investigator on the $100,000 grant.

First Solar to Build New Solar Plant for NRG
Mar 12, 2012 12:05 PM E
First Solar Inc will build a 26-megawatt solar power plant for power producer NRG Energy Inc in Arizona under the latest deal between two of the biggest players in the U.S. renewable energy sector.
Gold = Good for Fuel Cells
Touch of Gold Improves Nanoparticle Fuel-cell Reactions
Mar 12, 2012 11:52 AM E
Advances in fuel-cell technology have been stymied by the inadequacy of metals studied as catalysts. The drawback to platinum, other than cost, is that it absorbs carbon monoxide in reactions involving fuel cells powered by organic materials like formic acid. A more recently tested metal, palladium, breaks down over time.

Butterfly Molecule may Aid Quest for Nuclear Clean-up Technology
Mar 12, 2012 11:18 AM E
Scientists have produced a previously unseen uranium molecule, in a development that could help improve clean-up processes for nuclear waste.

A Big Discovery in the Study of Neutrinos, Tiny Particles that Have a Big Role in the Universe
Mar 09, 2012 16:12 PM E
An international team of physicists has determined a key parameter, which governs how neutrinos behave. This discovery measures a critical linchpin in the study of the tiny particles and in advancing the understanding of how these building blocks of all things, from galaxies to tea cups, came to be.
