Neutrons provide insights into increased performance for hybrid perovskite solar cells
DOE/Oak Ridge National LaboratoryPeer-Reviewed Publication
Neutron scattering at Oak Ridge National Laboratory has revealed, in real time, the fundamental mechanisms behind the conversion of sunlight into energy in hybrid perovskite materials. A better understanding of this behavior will enable manufacturers to design solar cells with significantly increased efficiency.

Spinach used in neutron studies could unearth secret to stronger plant growth
DOE/Oak Ridge National Laboratory
Researchers from Uppsala University are using neutrons to study RuBisCO, an abundant enzyme essential to life on earth. They hope to determine how plants and other organisms use this enzyme to catalyze a reaction called carbon fixation that converts carbon dioxide into useful organic compounds.

Exceptionally efficient extraction may improve management of nuclear fuel
DOE/Oak Ridge National Laboratory
A team at the Department of Energy's Oak Ridge National Laboratory has designed and synthesized a selective molecular trap that can separate the minor actinide element americium from a mixture of americium and the lanthanide elements, using europium as the model lanthanide in experiments. Whereas recovered americium could be burned in nuclear reactors, lanthanides are 'neutron poisons' and must be disposed of in a geologic repository to decay.

Underground neutrino experiment sets the stage for deep discovery about matter
DOE/Oak Ridge National LaboratoryPeer-Reviewed Publication
In a study published in Physical Review Letters, collaborators of the MAJORANA DEMONSTRATOR, an experiment led by the Department of Energy's Oak Ridge National Laboratory, have shown they can shield a sensitive, scalable 44-kilogram germanium detector array from background radioactivity. This accomplishment is critical to developing and proposing a much larger future experiment -- with approximately a ton of detectors -- to study the nature of neutrinos.

ORNL researchers design novel method for energy-efficient deep neural networks
DOE/Oak Ridge National LaboratoryPeer-Reviewed Publication
Researchers at DOE's Oak Ridge National Laboratory (ORNL) have developed a novel method for more efficiently training large numbers of networks capable of solving complex science problems. Specifically, Mohammed Alawad, Hong-Jun Yoon, and Gina Tourassi of ORNL's Computer Science and Engineering Division, have demonstrated that by converting deep learning neural networks (DNNs) to 'deep spiking' neural networks (DSNNs) they can improve the efficiency of network design and training.
