Voltage Gated Ion Entry Into Two‐dimensional Angstrom‐Scale Channels
Advanced Functional Materials, EarlyView.We demonstrate voltage‐gated ion transport through artificial Å‐scale slit channels (∼4 Å high) formed by van der Waals assembly of 2D materials. At low electric fields, ions are excluded while water permeates. Above a threshold voltage, nonlinear hysteretic conduction emerges, driven by ion dehydration and concentration‐dependent barriers, mimicking ...

Cooperative gating between ion channels
General physiology and biophysics, 2014 Cooperative gating between ion channels, i.e. the gating of one channel directly coupled to the gating of neighboring channels, has been observed in diverse channel types at the single-channel level. Positively coupled gating could enhance channel-mediated signaling while negative coupling may effectively reduce channel gating noise.

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure
Advanced Functional Materials, EarlyView.We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Reptation theory of ion channel gating
Biophysical Journal, 1990 Reptation theory is a highly successful approach for describing polymer dynamics in entangled systems. In turn, this molecular process is the basis of viscoelasticity. We apply a modified version of reptation dynamics to develop an actual physical model of ion channel gating.

Effects of hydrophobic mismatch and spontaneous curvature on ion channel gating with a hinge
, 2018 We analyze the energetics of an ion-channel gating, focusing on effects of hydrophobic mismatch between the channel protein and the nearby lipid molecules, spontaneous curvature of monolayers, and thickness change of membranes.
