The discovery of MCM-41 and its relatives has spawned a revolution in the design and synthesis of tailored mesostructured oxide-based materials. By comparison, non-oxidic solids such as sulfides or selenides are only very little exploredÐpartly because of difficulties in handling or obtaining relevant precursors (e.g., [SiS4] 4± units). Direct sulfur and selenium analogs of MCM-41 type material...

Sulfur compounds have been considered as potential thermoelectricmaterials due to recently reported high ZT values. However, the synthetic methods for these compounds are too expensive or complicated to be applied to large-scale production. Among these compounds, tin sulfide (SnS) has attracted increasing attention not only because of its extremely low thermal conductivity (below 1.0 W (m K) ) ...

The effects of dietary tin on tin and calcium metabolism were determined in eight adult males. Subjects were fed mixed diets containing 0.11 mg tin daily (control diet) and 49.67 mg tin daily (test diet) for 20 days each in a cross-over design. The level of tin in the control diet was typical of the level of tin found in diets that contained only fresh and frozen foods; the level of tin in the ...

Highly stable sulfur/microporous carbon (S/MC) composites are prepared by vacuum infusion of sulfur vapor into microporous carbon at 600 °C, and lithium sulfide/microporous carbon (Li2S/MC) cathodes are fabricated via a novel and facile in situ lithiation strategy, i.e., spraying commercial stabilized lithium metal powder (SLMP) onto a prepared S/MC film cathode prior to the routine compressing...

Metallic sulfide anodes show great promise for sodium-ion batteries due to their high theoretic capacities. However, practical application is greatly hampered by poor electrochemical performance because of the large volume expansion sulfides and sluggish kinetics Na+ ions. Herein, a porous bimetallic SnS/Sb2S3 heterostructure constructed that encapsulated in sulfur nitrogen codoped carbon matri...
