The lithium–sulfur (Li–S) system is an attractive candidate to replace the current state-of-the-art lithium-ion battery due to the promising theoretical charge capacity of 1675mAh/g and energy density of 2500Wh/kg; however, the dissolution of intermediate polysulfides into the organic liquid electrolyte during cycling hinders its practical realization. We report the synthesis of mesoporous graphene–silica...
The equation of motion for a peak in a gas chromatography experiment is shown to be exact whenever the column outlet pressure is approximately zero. Based on steady-state assumptions, this equation is solved for an isothermal analysis with a single-ramp inlet-pressure or flow-rate program. Theoretical calculations of retention times are confirmed experimentally for two n-alkanes using a capillary...
