A Parallel Electromagnetic Molecular Logic Gate
Journal of the American Chemical Society, 2005A theoretical study of transport through a three-terminal molecular ring in the presence of a magnetic field is presented. The physical principles necessary to achieve logic operations based on the Aharonov-Bohm effect are discussed. We show that a proper combination of a gate potential and a realistic magnetic field can be used to obtain parallel ...

Edge-on Gating Effect in Molecular Wires
Nano Letters, 2015This work demonstrates edge-on chemical gating effect in molecular wires utilizing the pyridinoparacyclophane (PC) moiety as the gate. Different substituents with varied electronic demands are attached to the gate to simulate the effect of varying gating voltages similar to that in field-effect transistor (FET).

Molecular mechanisms of gated ion channels
Bioelectrochemistry and Bioenergetics, 1986Abstract Ion channels form the basis for intercellular communication in biological systems. With the advent of cloning techniques, it is now possible to sequence the proteins that form such channels. The acetylcholine receptor, for example, which consists of five subunits, and the voltage gated sodium channel have been completely sequenced by Noda et

Electrostatic Gate Control in Molecular Transistors
Topics in Current Chemistry, 2018Molecular transistors, in which single molecules serve as active channel components in a three-terminal device geometry, constitute the building blocks of molecular scale electronic circuits. To demonstrate such devices, a gate electrode has been incorporated in several test beds of molecular electronics.

The Journal of Physical Chemistry B, 2009
The spinach plant aquaporin SoPIP2;1 is a gated water channel, which switches between open and closed states depending on the conformation of a 20-residue cytoplasmic loop, the D-loop. Using fully atomistic molecular dynamics simulations, we have investigated the possibility of driving the conformational equilibrium of the protein toward a ...

A Rotary Molecular Motor Gated by Electrical Energy
Organic Letters, 2014DFT calculations predict that the chiral pentiptycene derivative E-1 possesses distinct rotational potential energy surfaces in the neutral vs the radical anionic (E-1(•-)) form such that continued electrochemical switching between E-1 and E-1(•-) could lead to a directional rotation of the pentiptycene rotor about the exocyclic C-C bond.

A photoactivated molecular gate
2016A novel capped silica nanoscopic mesoporous hybrid material for photo-driven cargo release applications has been designed and prepared. The capped system, which shows a zero release, contains a photo-cleavable bulky o-methoxybenzylamine derivative. Upon irradiation at 254 nm, photo-degradation of the o-methoxybenzylamine framework and the subsequent ...

Molecular Structure, Gating, and Regulation
2014Gating of ion channels is the opening response of the channel to a stimulus and its subsequent desensitization or inactivation. For nicotinic acetylcholine receptors, the stimulus is the binding of the neurotransmitter acetylcholine to an extracellular domain followed by a sequence of conformational changes resulting in rapid channel opening.
