Effect of NaHS on carbonic anhydrase activity of human erythrocyte
Asian Journal of Medical Sciences, 2016 Background: In contrast to its role as poison, hydrogen sulfide (H2S) is recently considered as a gaso-transmitter which mediates important physiologic functions in humans.

Comparison between transport properties for H2+ in H2 and H2+ in Ar gas
Science of SinteringIn this work we present a cross-sections dataset and transport properties of H2+ in H2 gas and H2+ ions in Ar gas. The ionic charge transfer reactions with molecules are indispensable elementary processes in the modeling of kinetics in terrestrial, industrial, and astrophysical plasma in the detection of dark matter.

Advanced Science, EarlyView.By altering surface chemical bonds to prolong relaxation time and shift absorption to lower frequencies, SiC/rare earth–sulfur (RE─S, RE = La, Ce, Pr, Sm, Gd, Er) materials achieve excellent low‐frequency electromagnetic wave absorption under extreme conditions, offering a new direction for designing high‐performance SiC‐based absorbers.

Angewandte Chemie, EarlyView.A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.
