Abstract: Methods of manufacturing conductive molybdenum disulfide (MoS2) are described herein. The methods include mixing a molybdenum disulfide powder in a liquid to form a molybdenum disulfide suspension, sonicating the molybdenum disulfide suspension for a first period of time at a first temperature, and retrieving the conductive molybdenum disulfide from the sonicated molybdenum disulfide suspension. Methods of manufacturing conductive forms of other transition metal dichalcogenides are also described. Materials produced by the methods described herein are also described.

Abstract: The present application relates to sensors and methods for detecting and/or quantifying an oxidant such as free chlorine in a liquid sample such as drinking water. The sensors comprise a first electrode, a second electrode and a composite material between and connecting the first electrode and the second electrode, the composite material comprising a semiconductor and a redox-switchable organic compound associated therewith. The methods comprise exposing the liquid sample to the sensor under conditions to oxide the redox-switchable organic compound and analyzing a resulting change in current.
