Ultrahigh Seebeck Coefficient and Power Factor in Low‐Temperature Fused Ag2Se Films via Superionic‐Driven Plastic Deformation

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

Null controllability of semilinear degenerate parabolic equations in bounded domains

Electronic Journal of Differential Equations, 2006
In this paper we study controllability properties for semilinear degenerate parabolic equations with nonlinearities involving the first derivative in a bounded domain of R. Due to degeneracy, classical null controllability results do not hold in general.

Integrin‐Piezo1 Axis Drives ECM Remodeling and Invasion of 3D Breast Epithelium

Advanced Science, EarlyView.
Mechanical stiffening of the extracellular matrix around mature mammary acini induces sequential remodeling phases. An early response disrupts the basement membrane and promotes fibronectin secretion, followed by delayed invasion with matrix reorganization and proliferation.

Convergence analysis of option drift rate inverse problem based on degenerate parabolic equation

Results in Applied Mathematics
In this paper, we study the convergence of the inverse drift rate problem of option pricing based on degenerate parabolic equations, aiming to recover the stock price drift rate function by known option market prices.

Prolonged Cell Encapsulation and Gravity‐independent Filamented Light Biofabrication of Muscle Constructs

Advanced Science, EarlyView.
A gravity‐independent filamented light (G‐FLight) projection method is presented for rapid biofabrication of anisotropic tissues, demonstrated with muscle constructs as a target application. Specialized photocrosslinkable resins enable refrigeration or cryopreservation with encapsulated cells.

Quasiconformal mappings and degenerate elliptic and parabolic equations

Le Matematiche, 1987
In this paper two Harnak inequalities are proved concerning a degenerate elliptic and a degenerate parabolic equation. In both cases the weight giving the degeneracy is a power of the jacobian of a quasiconformal mapping.

Solar‐Powered Electrokinetic Filtration using Hierarchical Porous Membranes for the Off‐Grid Removal of Ultrafine Contaminants

Advanced Science, EarlyView.
A solar‐powered nanoelectrokinetic filtration system enables high‐flux removal of ultrafine contaminants without relying on nanoscale pores or pressure‐driven membranes, offering a sustainable solution for the off‐grid water purification. Abstract The removal of ultrafine suspended solids from water remains a critical challenge due to the tradeoffs ...

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

Advanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such
