Scientists record rapid carbon loss from warming peatlands

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Scientists at the Department of Energy's Oak Ridge National Laboratory have demonstrated a direct relationship between climate warming and carbon loss in a peatland ecosystem. Their study published in AGU Advances provides a glimpse of potential futures where significant stores of carbon in peat bogs could be released into the atmosphere as greenhouse gases.

Love-hate relationship of solvent and water leads to better biomass breakup

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Scientists at the Department of Energy's Oak Ridge National Laboratory used neutron scattering and supercomputing to better understand how an organic solvent and water work together to break down plant biomass, creating a pathway to significantly improve the production of renewable biofuels and bioproducts.

Colleen Iversen on belowground ecology

DOE/Oak Ridge National Laboratory

After working on a climate change experiment that showed plants adapt to additional carbon dioxide by putting extra carbon into their roots, Colleen Iverson has been on a mission to understand the role of roots in the environment, especially the tundra.

Summit helps predict molecular breakups

DOE/Oak Ridge National Laboratory

A team led by Shiwei Zhang at the Flatiron Institute and the College of William & Mary recently used the Summit supercomputer at the Oak Ridge Leadership Computing Facility to simulate transition metal systems--such as copper bound to molecules of nitrogen, dihydrogen, or water--and correctly predicted the amount of energy required to break apart dozens of molecular systems, paving the way for a greater understanding of these materials.

West Virginia researchers use neutrons to study materials for power plant improvements

DOE/Oak Ridge National Laboratory

Researchers from West Virginia University are using neutron scattering at Oak Ridge National Laboratory to study novel materials called high entropy oxides, or HEOs. Their goal is to collect insights into how the atoms in the HEOs bind together and whether the materials can be used to develop useful applications to improve power plant operations.

Process for 'two-faced' nanomaterials may aid energy, information tech

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A team led by the Department of Energy's Oak Ridge National Laboratory used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.
