Determination of Sulfur in Barite and Pyrite by High Frequency Infrared Carbon-Sulfur Spectrometer
Yankuang ceshi, 2017 Most sulfate and sulfide ores are composed of low electrical magnetic materials. In the process of combustion, the sulfur in sulfate and sulfide ores cannot be released completely, because it is difficult to produce a large enough electromagnetic ...

Crude oil desulfurization [PDF]
, 1982 High sulfur crude oil is desulfurized by a low temperature (25-80 C.) chlorinolysis at ambient pressure in the absence of organic solvent or diluent but in the presence of water (water/oil=0.3) followed by a water and caustic wash to remove sulfur and ...

Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Insulator-to-metal transition in sulfur-doped silicon [PDF]
, 2011 We observe an insulator-to-metal (I-M) transition in crystalline silicon doped with sulfur to non- equilibrium concentrations using ion implantation followed by pulsed laser melting and rapid resolidification. This I-M transition is due to a dopant known

Advanced Functional Materials, EarlyView.A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.
