Researchers Expose Hidden Atomic Portrait of Antioxidant Enzyme The mitochondria in human cells depend on manganese superoxide dismutase to keep the amount of harmful reactive oxygen molecules under control. Researchers have now obtained a complete atomic portrait of the enzyme, providing key information about the catalytic mechanism within its active site, situated between the green and blue subunits and the yellow and pink subunits.[ORNL/Jill Hemman] April 7, 2021 The mitochondria in human cells depend on manganese superoxide dismutase to keep the amount of harmful reactive oxygen molecule...

Date Time ‘Hinged’ atomic structures open door to next-gen solar power materials Neutron scattering data on the “hinged” atomic structure in an inorganic perovskite material could help scientists optimize other materials’ solar power storage and delivery properties. Credit: Jill Hemman/ORNL, U.S. Dept. of Energy Most solar power is produced by converting sunlight into electricity through the use of thin films made of semiconductor materials that absorb particles of light, called photons. These absorbed photons knock electrons loose from atoms in the thin film, and the free electrons...

Discovering a New Form Of Magnetism in 'Magnetic Graphene' Thought LeadersDr. Matthew CoakDepartment of Physics, The University of WarwickCavendish Laboratory, The University of Cambridge AZoNano speaks with Dr. Matthew Coak from the University of Warwick and the University of Cambridge, leader of an international team that has identified a new form of magnetism in so-called magnetic graphene - this could lead to new ways of understanding superconductivity in this unusual type of material. Can you give our readers a summary of your recent research? We have measured the magne...

About the role The ISIS Muon and Neutron Source has around 36 instruments, many of which require samples, neutron guides, beam absorbers and detectors to be moved remotely in a number of different geometric planes. To achieve this, mechatronics systems are used and these components are now vital to the success of many of the ISIS experiments. To help with maintaining and improving these mechatronics systems, the ISIS Design Division (IDD) now has a vacancy for a Real-Time Control Software Lead Engineer within the Electrical Design Group. Within this role, you will be the lead technical engine...
