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.

Ion-Channel Gating: Twist to open [PDF]
Current Biology, 1995 Three-dimensional images of the open state of the nicotinic acetylcholine receptor have been obtained at 9 A resolution. Comparison with the closed state reveals the structural basis of channel gating.

Advanced Functional Materials, EarlyView.Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity
Advanced Functional Materials, EarlyView.This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...
