Inverse problem of determining the coefficients in a degenerate parabolic equation
Electronic Journal of Differential Equations, 2014 We consider the inverse problem of identifying the time-dependent coefficients in a degenerate parabolic equation. The conditions of existence and uniqueness of the classical solution to this problem are established. We investigate the case of weak

Catalytic Electron‐Driven Non‐Equilibrium Phase Transition in Quantum Electronic Heterostructures
Advanced Science, EarlyView.This study proposes an innovative method to control the phase of heterostructured materials via electron flow manipulation. Leveraging this technique, a new topological phase is achieved that hosts excitons at the interface of a topological insulator.

Revealing a Pathway for Low‐Temperature Recrystallization in Germanium
Advanced Science, EarlyView.This study reports the discovery that energy transferred to electrons and atoms by highly ionizing ions results in a disorder‐order (amorphous‐crystalline) phase transformation in noncrystalline (amorphous) Ge. This discovery unlocks low‐temperature recrystallization pathways in Ge, offering a nonthermal strategy for fabricating Ge‐based devices that ...

Advanced Science, EarlyView.This study proposes a medium‐entropy strategy to enhance sodium vanadium fluorophosphate cathodes. The designed Na3Fe0.1Mn0.2Co0.2Ni0.3V1.2(PO4)2F3@CNTs composite enhances structural stability and charge transport. Entropy‐induced distortion and carbon nanotubes (CNTs) synergistically improve Na⁺/electron kinetics. In situ XRD reveals a reversible dual‐

On an Anisotropic Parabolic Equation on the Domain with a Disjoint Boundary
Journal of Function Spaces, 2018 Consider the anisotropic parabolic equation with the variable exponents vt=∑i=1n(bi(x)vxiqix-2vxi)xi, where bi(x),qi(x)∈C1(Ω¯), qi(x)>1, and bi(x)≥0. If {bi(x)} is not degenerate on Σp⊂∂Ω, a part of the boundary, but is degenerate on the remained part ∂Ω∖

Advanced Science, EarlyView.Driven by superionic‐induced plastic deformation, low‐temperature treatment can not only effectively fuse Ag2Se nanoparticles into a dense film but also enhance thermoelectric performance by maximally preserving effective grain boundaries resulting in intensive energy filtering effect. Notably, excess Ag nanoclusters act as fusing agents, promoting the
