Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

Polarized neutron scattering from clusters of polarized proton spins in solid material provides a new contrast variation method. Frozen solutions of apoferritin and of the large subunit of Escherichia coli ribosomes in a mixture of heavy water and deuterated glycerol have been studied at the conditions of dynamic nuclear spin polarization (H = 2.5 T, T < 1K, 4-mm microwave irradiation). The three basic scattering functions of contrast variation were derived by varying polarized neutron scattering with the polarization of target nuclei. They agree with results obtained from neutron scattering in H2O/D2O mixtures at room temperature. Furthermore, the proton spins appear to be polarized uniformly, at least to a structural resolution of 40 Å. This is an important prerequisite for the in situ structure determination of macromolecular labels in larger host particles.
