Charged Biological Membranes Repel Large Neutral Molecules by Surface Dielectrophoresis and Counterion Pressure
(American Chemical Society, 2024-01-16)
Macromolecular crowding is the usual condition of cells. The implications of the crowded cellular environment for protein stability and folding, protein-protein interactions, and intracellular transport drive a growing ...
African Swine Fever Virus Gene B117L Encodes a Small Protein Endowed with Low-pH-Dependent Membrane Permeabilizing Activity
(American Society for Microbiology, 2023-05-22)
African swine fever virus (ASFV) is causing a devastating pandemic in domestic and wild swine in Central Europe to East Asia, resulting in economic losses for the swine industry. The virus contains a large double-stranded ...
The Cytoplasmic Domain of the SARS-CoV-2 Envelope Protein Assembles into a β-Sheet Bundle in Lipid Bilayers
(Elsevier, 2023-01-28)
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope (E) protein forms a pentameric ion channel in the lipid membrane of the endoplasmic reticulum Golgi intermediate compartment (ERGIC) of the infected ...
Hysteresis in memristors produces conduction inductance and conduction capacitance effects
(Royal Society of Chemistry, 2024-04-15)
Memristors are devices in which the conductance state can be alternately switched between a high and a low value by means of a voltage scan. In general, systems involving a chemical inductor mechanism as solar cells, ...
Current-controlled memristors: resistive switching systems with negative capacitance and inverted hysteresis
(American Physical Society, 2023)
Resistive switching in memristors is being amply investigated for different
applications in non-volatile memory (RRAM), neuromorphic computing and
programmable logic devices. Memristors are conducting devices in which ...
High proton conductivity at low and moderate temperature in a simple family of Prussian blue analogs, divalent transition metal hexacyanocobaltates (III)
(Elsevier, 2020-11-10)
Proton conductivity behavior was studied in a family of hexacyanocobaltates with divalent transition metals (II), HCCMs. The HCCMs, with molecular formula M3[Co(CN)6]2∙xH2O (where M = Ni, Co, Fe, Mn and Cd), had cubic ...
Electrical conductivity of an all-natural and biocompatible semi-interpenetrating polymer network containing a deep eutectic solvent
(Royal Society of Chemistry, 2020-07-29)
A series of semi-interpenetrating polymer networks (semi-IPNs) consisting of crosslinked poly(itaconic
acid) in the presence of the polysaccharide inulin were prepared by free-radical polymerization, taking
advantage of ...
Bio-Nanocomposite Hydrogel Based on Zinc Alginate/Graphene Oxide: Morphology, Structural Conformation, Thermal Behavior/Degradation, and Dielectric Properties
(MDPI, 2020)
Bio-nanocomposite hydrogels based on sodium alginate (SA) as polymer matrix and
graphene oxide (GO) nanosheets with zinc as crosslinking agent were synthesized with the aim of
incorporating the intrinsic properties of ...
Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells
(American Chemical Society, 2020-10-01)
Negative capacitance in the low-frequency domain and inverted hysteresis are familiar features in perovskite solar cells, which origin is still under discussion. Here we use impedance spectroscopy to analyze these responses ...
In Situ Spectroscopic Ellipsometry for Thermochromic CsPbI3 Phase Evolution Portfolio
(American Chemical Society, 2020-04-09)
Thermochromism is a color change phenomenon for a compound when it undergoes a heating/cooling process. The observation of this phenomenon mostly relies on the naked eye, rather than an exact optical technique, which retards ...
