Magnetic‐Field Modulation of Charge Transport in Non‐Fullerene Semiconductors for Enhanced Hydrogen Evolution

Advanced Materials Interfaces, EarlyView.
ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...

Role of the C-terminal domain in the structure and function of tetrameric sodium channels [PDF]

, 2013
Voltage-gated sodium channels have essential roles in electrical signalling. Prokaryotic sodium channels are tetramers consisting of transmembrane (TM) voltage-sensing and pore domains, and a cytoplasmic carboxy-terminal domain.
