An ultrasonic nondestructive evaluation technique was developed to monitor liquid-phase evolution during heat treatment of high-T/sub c/ superconductors. The liquid phase is essential for microstructural and phase development of superconductors and i

The organic electron-donor molecule ET [bis(ethylenedithio)tetrathiafulvalene] was synthesized twice by the identical route: (a) with natural ( 12 C) carbon isotopic distribution; (b) with 95% 13 C, in the central CC double bond position. The supe

New synthetic routes to bis(ethylenedithio)tetraselenafulvalene (BETS) were explored, starting from tetraselenafulvalene (TSF). Several radical cation salts of TSF and BETS were prepared by electrocrystallization. A new kappa phase salt of BETS, K-(B
