Using nondestructive neutron scattering techniques, scientists are examining how single-celled organisms called cyanobacteria produce oxygen and obtain energy through photosynthesis.
After more than a year of operation at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.
Researchers used neutrons to probe a running engine at ORNL’s Spallation Neutron Source
The generation of bioethanol from lignocellulosic biomass holds great promise for renewable and clean energy production. However, this type of biomass is a complex, composite biological material that shows significant recalcitrance to enzymatic breakdown into sugars that can be used for fermentation, currently making it cost-ineffective as an ethanol source. The present research provides insight into the consequences of dilute acid pretreatment of biomass through direct observation by small-angle neutron scattering (SANS) of structural features in cellulose extracted from switchgrass over length scales from 10 to 6000 Ã….
