Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

open access: yesAdvanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

MELTING AND FORMING OF SER FUEL RODS [PDF]

open access: yes, 1960
Sixty-one metal alloy reds were fabricated for the SNAP Experimental Reactor (SER), a compact nuclear power source. These rads were 1 in. in diameter by 10 in. long and consisted of an alloy containing 7 wt.% highly enriched uranium and 93 wt.% zinconium. Melting of the alloy was done by generally accepted consumable-arc meltiag techniques.
