Plant genetic advance could lead to more efficient biofuel conversion

January 5, 2015 7:14 am | by Janet Lathrop, Univ. of Massachusetts, Amherst | News | Comments

Plant geneticists from the Univ. of Massachusetts Amherst and the Univ. of California, Davis have sorted out the gene regulatory networks that control cell wall thickening by the synthesis of the three polymers, cellulose, hemicellulose and lignin. The plant geneticists say that the most rigid of the polymers, lignin, represents “a major impediment” to extracting sugars from plant biomass that can be used to make biofuels.

Computational clues into the structure of a promising energy conversion catalyst

December 19, 2014 8:08 am | News | Comments

Hydrogen fuel is a promising source of clean energy that can be produced by splitting water into hydrogen and oxygen gas. The reaction is difficult but achievable with the help of a catalyst. However, current catalysts lack the efficiency required for water splitting to be commercially competitive. Recently, however, scientists have identified one such catalyst, iron-doped nickel oxide.
