An apparatus for nondestructive and rapid comparison of mask approaches in defense against infected respiratory aerosols

Donal Sheets, Jamie Shaw, Michael Baldwin +5

At the front lines of the world's response to the COVID-19 pandemic are hero-clinicians facing a lack of critical supplies including protective medical grade breathing masks and fi…

Exploring itinerant states in divalent hexaborides using rare-earth edge resonant inelastic X-ray scattering

Donal Sheets, Vincent Flynn, Jungho Kim +10

We present a study of resonant inelastic X-ray scattering (RIXS) spectra collected at the rare-earth edges of divalent hexaborides YbB and EuB. In both systems, RIXS-ac…

Negative thermal expansion near the precipice of structural stability in open perovskites

Connor A. Occhialini, G. G. Guzmán-Verri, Sahan U. Handunkanda +1

Negative thermal expansion (NTE) describes the anomalous propensity of materials to shrink when heated. Since its discovery, the NTE effect has been found in a wide variety of mate…

Large isotropic negative thermal expansion above a structural quantum phase transition

Sahan U. Handunkanda, Erin B. Curry, Vladimir Voronov +5

Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of ene…

Negative thermal expansion near two structural quantum phase transitions

Connor A. Occhialini, Sahan U. Handunkanda, Ayman Said +3

Recent experimental work has revealed that the unusually strong, isotropic structural negative thermal expansion in cubic perovskite ionic insulator ScF3 occurs in excited states a…

Kondo lattice excitation observed using resonant inelastic X-ray scattering at the Yb edge

Jason N. Hancock, Maxim Dzero, John Sarrao +4

We present a study of the resonant inelastic scattering response of \ybin\ excited at the tender Yb X-ray edge. In the high-temperature, paramagnetic phase, we observe a mult…
