Imagine an instrument that collects thousands of diffraction data points in days instead of months with the help of a cylindrical image plate detector and an intense polychromatic neutron beam. IMAGINE is the newest single crystal diffractometer being installed at the High Flux Isotope Reactor, and ...
Researchers have long thought that formation of insoluble fibrous āstringsā of self-assembling proteins might be involved in the progression of a number of diseases, including neurodegenerative disorders such as Alzheimerās and Parkinsonās. However, recent evidence suggests that aggregates that develop at an earlier stage than fibril formation, and accumulate in human organs, may be the primary toxic agents.
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 Ć .
