Origin of Enhanced Electromechanical Coupling in (Yb,Al)N Nitride Alloys

Gallium Nitride Nanowire Electromechanical Resonators

Flexural electromechanical coupling: a nanoscale emergent property of boron nitride bilayers.

The symmetry properties of atomically thin boron nitride (BN) monolayers endow them with piezoelectric properties, whereas the bulk parent crystal of stacked BN layers is not piezoelectric. This suggests potential for unusual electromechanical properties in the few layer regime. In this work, we explore this regime and discover that a bilayer consisting of two BN monolayers exhibits a strong me...

Electromechanical coupling I. Introduction.

In skeletal muscle fibres contraction is initiated by the action potential which travels inward along the transverse tubular system and causes in some way the release of Ca from the terminal cisternae of the sarcoplasmic reticulum (SR). Ca-release is probably controlled by a potential-sensor (intram em brane charge movement) in the wall of the T-system which in a triad is about 10 20 nm apart f...

numerical analysis of thermo-mechanical coupling in shape memory alloys

the phase transformation phenomenon due to the crystallographic change of shape memory alloys subjected to mechanical or thermal loading is very complicated. regarding the thermo-mechanical coupling effects in shape memory alloys, in case of high  loading rates, heat generation/absorption during the forward/reverse transformation, will lead in temperature-dependent variation and consequently af...

Electromechanical Coupling in Tubular Muscle Fibers

The tubular fibers of the claw-closer muscle of the scorpion have a central core containing nuclei and mitochondria. The myofibrils have the shape of thin lamellae (1 micro) extending radially from the core to the surface membrane (20 micro). The thick myofilaments are organized in a hexagonal array with orbits of 10-13 thin myofilaments. The ratio of thick-to-thin filaments is 1:5. Transverse ...
