A Miniaturized Autonomous Thermomagnetic Generator
Advanced Functional Materials, EarlyView.Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

Global well-posedness of damped multidimensional generalized Boussinesq equations
Electronic Journal of Differential Equations, 2015 We study the Cauchy problem for a sixth-order Boussinesq equations with the generalized source term and damping term. By using Galerkin approximations and potential well methods, we prove the existence of a global weak solution. Furthermore, we study

Exponential Energy Decay of Solutions for a Transmission Problem With Viscoelastic Term and Delay
Mathematics, 2016 In our previous work (Journal of Nonlinear Science and Applications 9: 1202–1215, 2016), we studied the well-posedness and general decay rate for a transmission problem in a bounded domain with a viscoelastic term and a delay term.

On a doubly degenerate parabolic equation with a nonlinear damping term
Boundary Value Problems, 2021 Consider a double degenerate parabolic equation arising from the electrorheological fluids theory and many other diffusion problems. Let v ε $v_{\varepsilon }$ be the viscous solution of the equation. By showing that | ∇ v ε | ∈ L ∞ ( 0 , T ; L loc p ( x

Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides
Advanced Functional Materials, EarlyView.Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

Advanced Functional Materials, EarlyView.Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Damping of Linear Nonadiabatic MHD Waves in a Flowing Prominence Medium
Advances in Astronomy, 2014 We study the effect of shear flow on the time damping of linear nonadiabatic magnetoacoustic waves in a solar prominence. We consider a homogeneous, isothermal, and unbounded medium permeated by a uniform magnetic field.
