A fast and efficient iron-based catalyst that splits hydrogen gas to make electricity, necessary to make fuel cells more economical, was reported by researchers at DOE's Pacific Northwest National Laboratory. It is the first iron-based catalyst that converts hydrogen directly to electricity. The result moves chemists and engineers one step closer to widely affordable fuel cells. http://phys.org/news281694746.html Chemistry Tue, 05 Mar 2013 08:32:35 EST news281694746 To make fuel cells more economical, engineers want a fast and efficient iron-based molecule that splits hydrogen gas to make electricity.

This effect was achieved, the team reports in their paper published in the journal Science, by exciting a hydrogen molecule with electrons and through the use of a crystal that is known for stable oscillations. http://phys.org/news272097759.html Physics Wed, 14 Nov 2012 07:20:02 EST news272097759 By delving into the interactions between a hydrogen molecule and muonic hydrogen, the heaviest hydrogen isotope to date, a team of researchers from academia and Pacific Northwest National Laboratory created a popular paper. http://phys.org/news249206950.html Chemistry Thu, 23 Feb 2012 08:30:01 EST news249206950 (PhysOrg.com) -- When it comes to driving hydrogen production, a new catalyst built at Pacific Northwest National Laboratory can do what was previously shown to happen only in nature: store energy in hydrogen and release that energy on demand. This new nickel-based complex drives the reaction but is not consumed by it. While slow, the catalyst wastes little energy. It turns electrons and protons into hydrogen. The hydrogen molecule holds the energy in a very small space until it is needed. The same catalyst then breaks the single bond in the hydrogen molecule, releasing electrons to do work. http://phys.org/news248598084.html Chemistry Thu, 16 Feb 2012 07:01:33 EST news248598084 A team headed by Dr. Takashi Kuroda, Senior Researcher, and Dr. Marco Abbarchi, Researcher, of the Quantum Dot Research Center, National Institute for Materials Science, in joint research with Hokkaido University, succeeded in controlling the few-particle quantum state of a semiconductor quantum dot, and changing its correlation energies. This research achievement will make it possible to develop semiconductor non-linear devices which enable stable drive with low power consumption. http://phys.org/news212406590.html Nanotechnology Fri, 24 Dec 2010 09:50:11 EST news212406590 (PhysOrg.com) -- Physicists in Europe have successfully glimpsed the motion of electrons in molecules. The results are a major boon for the research world. Knowing how electrons move within molecules will facilitate observations and fuel our understanding of chemical reactions. http://phys.org/news195652327.html Nanotechnology Sun, 13 Jun 2010 13:15:10 EST news195652327 (PhysOrg.com) -- Understanding how to create artificial photosynthesis, or tough, flexible high-temperature superconductors, or better solar cells, or a myriad other advances, will only be possible when we have the ability to image electrons by freezing time within a few quintillionths of a second. A leader in attosecond science tells how it's done. http://phys.org/news190640036.html Physics Fri, 16 Apr 2010 12:34:47 EST news190640036 (PhysOrg.com) -- Scientists at the National Institute of Standards and Technology and Indiana University have determined the most accurate values ever for a fundamental property of the element lithium using a novel approach that may permit scientists to do the same for other atoms in the periodic table. http://phys.org/news182630094.html Physics Wed, 13 Jan 2010 18:35:33 EST news182630094 Molecules of hydrogen are difficult to steer with electric fields because of the symmetrical way that charges are distributed within them. But now researchers at ETH Zurich have found a clever technique to get a grip on the molecules. Their findings are reported in Physical Review Letters and highlighted in the September 14 issue of Physics. http://phys.org/news172150377.html Physics Mon, 14 Sep 2009 12:33:27 EST news172150377 (PhysOrg.com) -- University of Missouri researchers recently showed how carbon nanostructures can be engineered to become excellent media for hydrogen storage, work that may be important for the advancement of hydrogen-energy technologies for vehicles and other applications, which have been slow to develop due to the lack of suitable storage materials. http://phys.org/news162195986.html Nanotechnology Fri, 22 May 2009 07:27:40 EST news162195986 Theoretical physicist Uwe Thumm and his colleagues Feng He and Andreas Becker not only work with some of the smallest molecules in the universe, but they now have found a way to control the motion of the molecules' building blocks, electrons and nuclei. http://phys.org/news145818018.html Physics Thu, 13 Nov 2008 17:00:18 EST news145818018
