Hou et al. [56] studied the interfacial electronic contact between sulfur and carbon hosts, and demonstrated that heating treatment was able to form more intimate contacts and achieve more effective electron transfer than mechanically milling. The key to solving the poor electron transport in sulfur cathodes is to form intimate contact between …

In petroleum liquids, sulphur is present in an organic form, but within petroleum gases sulphur may occur as hydrogen sulphide (H 2S), rendering the gas 'sour'. 'Sour' gas generally contains between 1 and 60 percent H 2S. The sulphur industry can be broadly divided into voluntary and involuntary categories. Voluntary
