Some Features of Geometric Nonlinear Damping on Isolation Performance
Journal of Physics: Conference Series, 2019 Abstract The addition of nonlinear characteristics to improve the dynamic performance of isolation systems and vibration absorbers has been extensively investigated in the past decades. Both nonlinear stiffness and nonlinear damping have been largely analysed. A common way in which this can be achieved in practice, is by arranging linear

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films
Advanced Materials, EarlyView.ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

A note on the effect of surface contamination in water wave damping [PDF]
, 2000 Asymptotic formulas are derived for the effect of contamination on surface wave damping in a brimful circular cylinder; viscosity is assumed to be small and contamination is modelled through Marangoni elasticity with insoluble surfactant. It is seen that

Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures
Advanced Materials, EarlyView.An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...

A Geometrically Transient Platform for Bioelectronic Implants
Advanced Materials, EarlyView.Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
