Molecular Dynamics Simulation Study of Solid Vibration Permeation in Microporous Amorphous Silica Network Voids

Membranes, 2019
Microporous silica membranes have silica polymer network voids smaller than 3 Å where only small gas molecules such as helium (2.6 Å) and hydrogen (2.89 Å) can be transported.

Structure and Oscillation of Membrane Potential in Block Copolypeptide Membranes.

membrane, 1997
Membranes solvent-cast from the triblock copolypeptide poly (γ-benzyl-L-glutamate) x-poly (L-leucine) y-poly (γ-benzyl-L-glutamate) x, in which the mole ratio of the constituent blocks was properly tailored, displayed a mesophase structure comprised of cylindrical domains of poly (γ-benzyl-L-glutamate) in a continuous matrix of poly (L-leucine ...

Mitogen‐induced oscillations of membrane potential and Ca²⁺ in human fibroblasts [PDF]

FEBS Letters, 1990
Using the whole‐cell technique, we have measured recurring hyperpolarizations induced by fetal calf serum and bradykinin in human fibroblasts. By coupling fura‐2 microfluorimetry to electrophysiology, we have also measured directly cytosolic Ca2+ and found that Ca2+ oscillations occur in synchrony with membrane currents. Mitogen stimulation of cells in

Speeding-up Screening of S1 SARS-CoV2 Inhibitors by Nanostructured Biomimetic ACE2 Sensors Based on a Superconductive Josephson Junction Toroidal Array Oscillating Effect

ECS Sensors Plus
We present a method for integrating a quantum superconductive oscillation effect, induced by a potential S1 SARS-CoV-2 inhibitor, which achieves a 99.992% blockade of S1 virus communication with a biomimetic angiotensin-converting enzyme 2 (ACE2) sensor.

DC-shifts in amplitude in-field generated by an oscillatory interference model of grid cell firing

Frontiers in Systems Neuroscience, 2014
Oscillatory interference models propose a mechanism by which the spatial firing pattern of grid cells can arise from the interaction of multiple oscillators that shift in relative phase. These models produce aspects of the physiological data such as the

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

Advanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...
