Impact of Structural Heterogeneities in Hierarchically Grown Microribbons on 2D WS2 Monolayer on the Measured Local Hydrogen Evolution Activity on Au Substrate

Small, Volume 22, Issue 10, 17 February 2026.
Spatially resolved SECCM measurements reveal that hierarchically grown microribbons on 2D WS2 drastically suppress local HER activity. Relative to the basal plane of the 2D monolayer directly supported on an Au substrate, single‐layer and multilayer microribbons exhibit more than a ∼5‐fold and >10‐fold decrease in current density, respectively.

Small Signal Dynamic Model of a Self-Synchronising Current Regulated Rectifier for a Permanent Magnet Wind Energy Conversion System (WECS)

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
Permanent magnet synchronous generators (PMSGs) are attractive for wind energy applications since they can both self-excite and operate at high power densities. Recent work has shown how the rectifiers for these systems can self-synchronise to the stator output voltage using a phase-locked-loop (PLL), and thus control the stator current without ...
