Mechanical testing device for in situ experiments on reversibility of dislocation motion in silicon

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2003
Abstract We present a general-purpose mechanical testing device built and tested for in situ experiments using synchrotron radiation. A new setup was used in order to investigate the reversibility of dislocation motion under stress reversal. The observations were done by in situ transmission X-ray topography, at the ID 19 beamline of the ESRF ...

ESF Clutch Driven Mechanisms and the ER Linear Reversing Motion Demonstrator

2001
The ESF clutch is formed by enclosing fluid between driver and driven plates and exciting it magnetically or electrostatically, or both, thereby enabling a torque or force transmission depending on whether the applied motion is rotary or linear respectively.

First integrals and families of symmetric periodic motions of a reversible mechanical system

Journal of Applied Mathematics and Mechanics, 2006
The author investigates a reversible mechanical system which admits first integrals. It is established that on symmetric motions the constants of asymmetric integrals equal to zero. Also the author determines the form of integrals of a reversible linear periodic system which correspond to zero characteristic exponents as well as the structure of the ...

Mechanical motion in the solid state and molecular recognition: reversible cis–trans transformation of an organic receptor in a solid–liquid crystalline state reaction triggered by anion exchange

CrystEngComm, 2015
An organic receptor [C28H24N4]2+ can be obtained with its unusual cis-form when it is ion-paired with a [Zn(dmit)2]2− coordination complex anion with the isolation of [C28H24N4][Zn(dmit)2]·2DMF (2). Compound 2 shows reversible cis–trans isomerization of the cationic receptor in a solid to solid transformation in a solid–liquid interface reaction.

Rejuvenation of Mechanical Fatigue Resistance in 2D Ferroelectric CuInP ₂ S ₆ by Reversing Ionic Motion

Small
ABSTRACT Fatigue degradation remains an intrinsic reliability bottleneck for conventional ferroelectric oxides, where irreversible ionic defect accumulation leads to progressive failure. In contrast, 2D van der Waals (vdW) ferroelectrics feature inherently defect‐suppressed interfaces and weak interlayer coupling,
