  • A recent study conducted by ORNL researchers and colleagues has shown that a Na-ion cathode Fe3P5SiO19 with two types of XO4n- (X = P and Si; n ≥2) groups exhibit a reversible capacity of ca. 70 mAh g-1, i.e., 1.7 Na+ ions per formula can be reversibly inserted/extracted at an average voltage of 2.5 V versus Na+/Na. To understand the Na+-ion conduction pathway, bond valence sum (BVS) mismatch minimization procedure was performed.

  • Redistribution of electronic clouds causes a lattice instability and freezes the flow of heat in highly efficient tin selenide. The crystal lattice adopts a distorted state in which the chemical bonds are stretched into an accordion-like configuration, and makes an excellent thermoelectric because heat propagation is thwarted.

  • The United States is running out of the plutonium-238 used to power decades-long missions to the edge of the solar system and beyond. Plans for producing more rely on two ORNL facilities: the Radiochemical Engineering Development Center, known as REDC, and the High Flux Isotope Reactor, known as HFIR.

  • Model electron spin maps of the iron-tellurium-sulfur material. The top row, a-c, shows three models of electron spin correlations, with the red and green colors of the peaks and corresponding planar projections below each model representing oppositely oriented spins. The images on the bottom, d-f, show the resulting neutron scattering patterns for each case.
