Zinc Sulfide Enabling Remarkable Surface Passivation of Crystalline Silicon
Advanced Energy Materials, EarlyView.Polycrystalline ZnS films capped by Al2O3 provide outstanding surface passivation performance. The excellent lattice agreement between c‐Si and ZnS combined with a hydrogenation step result in extremely low interface state density (≈ 1×1010 cm−2 eV−1) and recombination current pre‐factor (1.0 fA/cm2), revealing a new passivation strategy for ...

Halimeter ppb Levels as the Predictor of Erosive Gastroesophageal Reflux Disease
Gut and Liver, 2010 Background/Aims: In a previous issue published in Gut and Liver, we found that erosive changes in the esophagogastroduodenal mucosa were strongly correlated with increased levels of volatile sulfur-containing compounds (VSC), suggesting that halitosis ...

H2S as a Sulfur Source in Lemna minor L.: Effect on Growth, Sulfur Content and Sulfur Uptake [PDF]
, 1974 Lemna minor L. was cultivated with 6 ppm H2S in atmospheric air. Compared to organisms in H2S-free air, it had a smaller but constant specific growth rate for 36 days. It showed a pronounced increase in sulfate concentration.

Effect of Simulated Coal-Derived Gas Composition on H2S Poisoning Behavior Evaluated Using a Disaggregation Scheme [PDF]
, 2009 H2S poisoning is an important issue for solid oxide fuel cells (SOFCs) operated with syngas. The effect of simulated coal-derived gas composition on H2S poisoning behavior was evaluated using a disaggregation scheme where the influence of H2 content was ...

Kinetics of H2S sorbtion on manganese oxide and Mn-Fe-Cu mixed oxide prepared by the Complexation Technique [PDF]
, 2006 Hydrogen sulfide sorption activities of manganese oxide and Mn-Fe-Cu mixed oxide sorbents were examined in a fixed bed reactor. Sulfur retention capacity of Mn-O sorbent was found to be quite high at 600 degrees C both in the absence and presence of ...
