Scientists used neutron scattering to study how tweaking the ionic clusters in ionizable polymer solutions affects their structure. The polymer building blocks are marked in gold and the ionizable groups in red. Findings could open doors to lighter, more efficient clean energy devices.

Electrolytes that convert chemical to electrical energy underlie the search for new power sources with zero emissions. Among these new power sources are fuel cells that produce electricity.

3D printed Frankenstein design collimator show the scars where the individual parts are joined

Scientists at ORNL have developed 3-D-printed collimator techniques that can be used to custom design collimators that better filter out noise during different types of neutron scattering experiments

Electric vehicles can drive longer distances if their lithium-ion batteries deliver more energy in a lighter package. A prime weight-loss candidate is the current collector, a component that often adds 10% to the weight of a battery cell without contributing energy.

It would be a challenge for any scientist to match Alexey Serovs rate of inventions related to green hydrogen fuel. But this researcher at ORNL has 84 patents with at least 35 more under review, so his electrifying pace is unlikely to slow down any time soon.
