Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Corrosion of Candidate Materials for Use in Alkaline Water Electrolysis

CORROSION 2019, 2019
Abstract In alkaline water electrolysis the capital expense (CAPEX) of the electrolyzer unit is high and cost reduction, wherever possible, is highly desired. Many parts are made of expensive nickel-based alloys, which in some cases may be an overly conservative option.
