Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

open access: yesAdvanced Functional Materials, EarlyView.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Weak consistency of the Euler method for numerically solving stochastic differential equations with discontinuous coefficients

open access: yes, 1998
We prove that, under appropriate conditions, the sequence of approximate solutions constructed according to the Euler scheme converges weakly to the (unique) solution of a stochastic differential equation with discontinuous coefficients. We also obtain a

Inverse Design of Amorphous Materials With Targeted Properties

open access: yesAdvanced Materials, EarlyView.
AMDEN is a diffusion model framework for the inverse design of amorphous materials with targeted properties. By incorporating Hamiltonian Monte Carlo refinement into the denoising process, the framework overcomes the challenge of generating thermally relaxed disordered structures.

L p theory of second-order elliptic operators with discontinuous coefficients

open access: yes, 2020
A study was conducted to demonstrate Lp theory of second-order elliptic operators with discontinuous coefficients. The existence and uniqueness of a weak solution in the class with first derivatives from Lp was analyzed for a divergence-form elliptic ...

L^{p,λ} regularity for divergence form elliptic equations with discontinuous coefficients

open access: yesLe Matematiche, 2002
We will prove L^{p,λ} regularity results for the gradient of the solution to Dirichlet problem for some equations equations with coefficients in particular spaces.

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

open access: yesAdvanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Elliptic equations with discontinuous coefficients in unbounded domains of R^2

open access: yesLe Matematiche, 1996
In this paper we are concerned with second order elliptic equations in unbounded domains Ω of R^2 . We establish existence and uniqueness theorems under the assumptions that the leading coefficients are bounded and measurable in Ω and satisfy a suitable ...

Discontinuous Galerkin finite element approximation of non-divergence form elliptic equations with Cordes coefficients [PDF]

open access: yes, 2012
Non-divergence form elliptic equations with discontinuous coefficients do not generally posses a weak formulation, thus presenting an obstacle to their numerical solution by classical finite element methods.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.
