Big Science tools for clean transportation: neutron scattering at ORNL

Green Car Congress

In the case of ORNL’s SNS, the target is mercury. For some areas of neutron-assisted research, such as the investigation of advanced Li-ion batteries, this is crucial.). Projects have included producing two- and three-dimensional images of exhaust gas recirculation (EGR) coolers and images of diesel particulate filters (DPFs).
