Superconductivity of the Ternary Boride Li_2Pd_3B Probed by ^{11}B NMR [PDF]

, 2005
We report a ^{11}B NMR measurement on the recently discovered superconductor Li_2Pd_3B. The nuclear spin lattice relaxation rate 1/T_1 shows a well-defined coherence peak just below T_c (H=1.46 T)=5.7 K, and the spin susceptibility measured by the Knight

Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3−$$ {\mathrm{NO}}_3^{-} $$ coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous ...
