Advanced Materials, EarlyView.Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.

Oscillation criteria of the second-order nonlinear neutral difference equations
, 2020 This paper is concerned with oscillation of second-order nonlinear dynamic equations of the form r t y t p t y τ t f 2 t, y δ 2 t 0 on time scales. By using a generalized Riccati technique and integral averaging techniques, we establish new oscillation ...

Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors
Advanced Materials, EarlyView.Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

THE OSCILLATION CRITERIA FOR NONLINEAR NEUTRAL DIFFERENTIAL EQUATIONS
Demonstratio Mathematica, 2005 The authors discuss the problem of oscillation of a class of nonlinear neutral type integro-differential equations with continuous distributed delays. They give a necessary and sufficient and a sufficient condition for oscillation.

Directional Confinement Governed Ion Transport for Efficient Actuation
Advanced Materials, EarlyView.Structural anisotropy provides an effective means to regulate ion transport in polymer electrolytes. Directionally aligned channels formed by freeze‐drying provide continuous pathways for ion migration, enhancing ion mobility and simultaneously improving the strain and blocking force of ionic actuators.

Oscillation criteria for second-order nonlinear perturbed differential equations
Electronic Journal of Differential Equations, 2014 In this article, we study the oscillation of solutions to the nonlinear second-order differential equation $$ \Big(r(t)\psi(x(t))|x'(t)|^{\alpha-1}x'(t)\Big)' +P(t,x'(t))\psi(x(t))+Q(t,x(t))=0. $$ We obtain sufficient conditions for the oscillation
