Scientists Report Remarkable Enhancement of α-particle Clustering in Uranium Isotopes

Chinese Academy of Sciences It is always exciting to find new isotopes with extreme neutron/proton numbers in nuclear physics research. In the region of heavy nuclei, α-decay is one of the pervasive decay modes and plays an essential role in searching for new isotopes. However, even after about a century of studying α-decay, scientists still cannot perfectly describe how the α-particle is formed at the surface of the nucleus before its emission. In the α-decay process, the α-particle can be regarded not only as two protons plus two neutrons, but also as two proton-neutron pairs. Although previous studies have proved the importance of the pairing forces between the identical nucleons, it remains unclear whether the strong proton-neutron interactions have an impact on α-decay properties, especially in the heavy nuclear region.

Unique X-Ray Instrument Reveals New Things About Lithium-Rich Battery Materials

Unique X-Ray Instrument Reveals New Things About Lithium-Rich Battery Materials Written by AZoMApr 12 2021 An international research group working at the Lawrence Berkeley National Laboratory (Berkeley Lab) of the U.S. Department of Energy (DOE) has gained a better understanding of lithium-rich battery materials with the help of a special X-ray instrument.

The researchers focused their investigations on a material called lithium manganese oxide (Li2MnO3), the extreme example of so-called lithium-rich materials, containing the largest amount of lithium possible within this family of materials. A recently developed tenet of the battery community is that battery electrodes composed of lithium-rich materials could offer high-voltage, high-capac
