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∖

The cauchy problem of a degenerate parabolic equation

Monatshefte f�r Mathematik, 1977
This note is concerned with the existence of a weak solution for a degenerate Cauchy problem of parabolic type in then-dimensional spaceRn. The degenerate property is in the sense that the matrix (aij(t,x)) involved in the differential operator is not necessarily positive definite.

Overcome Limited Efficiency in All‐Perovskite Tandem Solar Cells Upon Light Management at Top Perovskite‐ Transparent Electrode Interfaces

Advanced Electronic Materials, EarlyView.
To further boost the PCE (power conversion efficiency) in all‐perovskite tandem solar cells (APTSCs), optimizing their optical structures is essential. In this study, it is found that the efficiency limitation in APTSCs is primarily due to reflective optical losses at the top perovskite interface.

The classical solvability for a one-dimensional nonlinear thermoelasticity system with the far field degeneracy

Advanced Nonlinear Studies
We study the local classical solvability of the Cauchy problem to the equations of one-dimensional nonlinear thermoelasticity. The governing model is a coupled system of a nonlinear hyperbolic equation for the displacement and a parabolic equation for ...

Enhancing Thermoelectric Performance of Cd₃P₂ by Alloying with Dirac Material Cd₃As₂

Advanced Electronic Materials, EarlyView.
This study demonstrates that alloying Cd₃P₂ with Dirac material Cd₃As₂ significantly enhances its thermoelectric performance. Key improvements include increased carrier mobility, reduced effective mass, and lower deformation potential, resulting in a doubled power factor and improved thermoelectric efficiency, which renders this material applicable for

Local Fermi Level Engineering in 2D‐MoS2 Realized via Microcontact Printing of Self‐Assembled Monolayers for Next‐Generation Electronics

Advanced Electronic Materials, EarlyView.
2D transition metal dichalcogenides (TMDCs) are promising for next‐gen optoelectronics. Their sensitivity to surroundings affects their electronic behavior. Substrate surfaces are chemically engineered to locally dope and adjust the properties of single layer MoS2 FETs employing self‐assembled monolayers (SAMs) arranged in patterns.

Memory Manufacture Under Microgravity (MMuM): In‐Space Manufactured ZnO‐Based Resistive Random Access Memory for Emerging Computing Application

Advanced Electronic Materials, EarlyView.
This paper presented ZnO‐based crossbar RRAMs by electrohydrodynamic (EHD) printing technology under in‐space manufacture environment as microgravity (µG). The crossbar structures of Ag/ZnO/Ag are fabricated under earth with in‐space microgravity. With the microgravity effect, a significant electroforming forming voltage reduced 89.3% as a storage ...

Large time behavior of solution to a class of doubly nonlinear parabolic equations

Electronic Journal of Differential Equations, 1994
solutions of the doubly degenerate parabolic equation $u_t={ m div} (|u|^{m-1}|abla u|^{p-2}abla u)$ in a cylinder $Omegaimes R^+$, with initial condition $u(x,0)=u_0(x)$ in $Omega$ and vanishing on the parabolic boundary $partialOmegaimes R^+$.
