. In this paper we investigate two free boundary problems for a Lotka-Volterra type competitionmodel in one space dimension. The main objective is to understand the asymptotic behavior of the twocompeting species spreading via a free boundary. We prove a

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Advanced Functional Materials, EarlyView.Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses
Advanced Functional Materials, EarlyView.An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

Advanced Functional Materials, EarlyView.Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Free boundary problems are of great importance, both physically and mathematically. Free boundary problems are boundary value problems for partial differential equations where an unknown moving boundary must be determined.

Some uniqueness results for Bernoulli interior free-boundary problems in convex domains
Electronic Journal of Differential Equations, 2002 We establish the existence of a elliptic family of convex solutions for Bernoulli interior free-boundary problems in bounded convex domains. We also proved that there is a unique solution to the problem associated with the so-called Bernoulli constant ...

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts
Advanced Functional Materials, EarlyView.The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...
