To take full advantage of biomass, lignin needs to be processed into usable components along with the plant cellulose. Currently, that process requires an acid plus high heat, or pyrolysis -- treating with high heat in the absence of oxygen. Besides being energy-consuming processing methods, the results are less than optimal. Ames Laboratory scientists are working to develop a method to deconstruct lignin in a way that is economically feasible and into stable, readily useful components.

Ames Laboratory scientists have found new insight to the “rules” of how magnetic states emerge and are suppressed, creating a guide for discovery of other materials with superconducting capabilities. The discovery was made through the study of the transition metal compound LaCrGe3 under temperature, pressure, and magnetic field changes.
A new rare-earth magnet recycling process developed by researchers at the Critical Materials Institute (CMI) dissolves magnets in an acid-free solution and recovers high purity rare earth elements. For shredded magnet-containing electronic wastes, the process does not require pre-processing such as pre-sorting or demagnetization of the electronic waste.
Scientists at the U.S. Department of Energy’s Ames Laboratory were able to successfully manipulate the electronic structure of graphene, which may enable the fabrication of graphene transistors-- faster and more reliable than existing silicon-based transistors.
Iver Anderson, senior metallurgist at the U.S. Department of Energy’s Ames Laboratory, and his team are winners of a 2017 Excellence in Technology Transfer Award from the Federal Laboratory Consortium (FLC) Mid-Continent Region.
