Unapposed hemichannels (HCs) formed by hexamers of gap junction proteins are now known to be involved in various cellular processes under both physiological and pathological conditions. On the other hand, less is known regarding how differences in the molecular composition of HCs impact electrical synaptic transmission…

Electrical synapses are known to promote synchrony and speed in neuronal systems. However, other studies have found that electrical synapses can have the opposite effect by desynchronizing network neurons. Although they are mechanistically simple, electrical synapses can have unintuitive effects on neuronal network…

Flexibility of rhythmic networks includes neuromodulator-elicited changes in neuronal participation between networks. We are examining the role of rectifying electrical synapses in this neuronal switching. Electrical synapses can have complex, non-intuitive effects on network output. However, it is often difficult to…

The purpose of this article is to review the current status of a frontier in dynamic spintronics and contemporary magnetism, in which much progress has been made in the past decade, based on the creation of a variety of micro- and nano-structured devices that enable electrical detection of magnetization dynamics. The…

Rectification, the tendency of bidirectional ionic conductors to favor ion flow in a specific direction, is an intrinsic property of many ion channels and synthetic nanopores. Despite its frequent occurrence in ion channels and its phenomenological explanation using Eyring’s rate theory, a quantitative relationship…

Under physiological conditions, mammalian PIEZO channels (PIEZO1 and PIEZO2) elicit transient currents mostly carried by monovalent and divalent cations. PIEZO1 is also known to permeate chloride ions, with a Cl^-^ / Na^+^ permeability ratio of about 0.2. Yet, little is known about how anions permeate PIEZO channels.…

Magnetoelectric materials convert magnetic fields to electric fields and have applications in wireless data and power transmission, electronics, sensing, data storage, and biomedical technology. For example, magnetoelectrics could enable precisely timed remote stimulation of neural tissue, but the resonance frequencies…

The paper demonstrates that a two-dimensional ballistic nanodevice in which the electron gas satisfies either the Schrödinger equation (as in quantum wells in common semiconductor heterostructures) or the Dirac equation (as in graphene) is able to rectify an electric signal if the device has a non-uniform cross…

Iontronic devices link ion-based transport with established electronic systems. Emerging capacitive devices, like CAPode and G-Cap, feature diode-like rectification and transistor-like switching, respectively, through electrochemical capacitor functionality for enhanced energy storage and signal processing in…

The dissipation of electrochemical gradients through ion channels plays a central role in biology. Herein we use voltage responsive kinetic models of ion channels to explore how electrical and chemical potentials differentially influence ion transport properties. These models demonstrate how electrically driven flux is…

'Shyamsunder Erramilli' 'Onuttom Narayan'] We report on a novel rectification phenomenon in a 2-D lattice network consisting of N × N sites with diode and AC source elements with controllable phases. A phase cascade configuration is described in which the current ripple in a load resistor goes to zero in the large N…

A novel 2.4 GHz high-efficiency rectifier circuit suitable for working under very-low-input electromagnetic (EM) power conditions (−20 to −10 dBm) is proposed for typical indoor power harvesting. The circuit features a SMS7630 Schottky diode in a series with a voltage booster circuit at the front end and a…

For the first time a printable, miniaturized and gate-controlled electrochemical capacitor-diode (G-CAPode) is presented. The heart of the device consists of a recently developed asymmetric electrical double-layer capacitor system based on selective, size-depended ion adsorption. Due to the introduction of a sieving…

Modern societies would not survive without electricity and at the same time electrical faults could cause and have caused many catastrophes-mainly deadly fires-to our societies. There are two types of electricity sources: the voltage source such as generators, charged batteries and capacitors, and the current source…

The paper is intended to introduce power conversion principles and to define common terms in the domain. The concepts of sources and switches are defined and classified. From the basic laws of source interconnections, a generic method of power converter synthesis is presented. Some examples illustrate this systematic…

Higher voltage from a lower one can be obtained using a stepup transformer(Kasatkin & Nemtsov 1986). Here such a circuit is analysed and quantitative relations between various parameters are derived for the sake of easy tailoring of the circuit as per ones requirement. It consists of a pulsative current drive circuit…
