Affordable fuel cells closer: Synthetic molecule first electricity-making catalyst to use iron to split hydrogen gas

February 18, 2013 – 6:00 pm
  • Affordable fuel cells closer: Synthetic molecule first electricity-making catalyst to use iron to split hydrogen gas - To make fuel cells more economical, engineers want a fast and efficient iron-based molecule that splits hydrogen gas to make electricity. Researchers now report such a catalyst. 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.(10.1038/nchem.1571)

    Scientists confirm original tetrahedral model of molecular structure of water

    February 12, 2013 – 11:00 am
  • Scientists confirm original tetrahedral model of molecular structure of water - Researchers have confirmed the original model of the molecular structure of water and have thus made it possible to resolve a long-standing scientific controversy about the structure of liquid water. The tetrahedral model was first postulated nearly 100 years ago and it assumes that every water molecule forms a so-called hydrogen bond with four adjacent molecules. This concept was almost toppled in 2004 when an international research group announced that it had experimentally established that water molecules form bonds only with two other molecules.(10.1038/ncomms2459)
