Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles
Advanced Engineering Materials, EarlyView.Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Classical and Quantum Gravity, 1997 Gravitational instantons are solutions of the Einstein field equations with Euclidean signature and anti-selfdual curvature. In this letter, the authors try to add a little bit more to our knowledge of instantons by presenting new instanton solutions of the Einstein field equations, which they obtain by means of a reduction of the complex Monge-Ampère ...

Gravitational decoherence [PDF]
Classical and Quantum Gravity, 2017 We discuss effects of loss of coherence in low energy quantum systems caused by or related to gravitation, referred to as gravitational decoherence. These effects, resulting from random metric fluctuations, for instance, promise to be accessible by relatively inexpensive table-top experiments, way before the scales where true quantum gravity effects ...

Advanced Functional Materials, EarlyView.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Nuclear Physics B - Proceedings Supplements, 1994 In the last few years there have been a number of significant developments in research towards the detection of gravitational radiation from astronomical objects. The construction of 3 large-scale (3- or 4-km) interferometric detectors has been funded; new high-sensitivity bars are under construction; there is a serious proposal using two ...

Gravitational helioseismology? [PDF]
Physical Review D, 1996 The magnitudes of the external gravitational perturbations associated with the normal modes of the Sun are evaluated to determine whether these solar oscillations could be observed with the proposed Laser Interferometer Space Antenna (LISA), a network of satellites designed to detect gravitational radiation.
