w-Invexity and optimality problem

Journal of Taibah University for Science
As the development of a family of preinvex functions, we define the w-invex set and a class of real functions. These are functions with the names w-preinvex, w-strictly preinvex, w-prequasi-invex, w-strictly prequasi-invex, w-semi-strictly prequasi-invex,

Soft Magnetic Artificial Muscles with High Work Density and Actuation Strain via Dual Cross‐Linking Design

Advanced Functional Materials, EarlyView.
A high‐performance magnetic composite actuator that integrates covalent and reversible physical cross‐links within a stiffness‐tunable polymer matrix embedded with functionalized magnetic particles is presented. The actuator exhibits programmable magnetic responsiveness, a stiffness switching ratio of 1.37 × 103, stretchability up to 1274%, large ...

Magnetic Unclonable Functions Leveraging Remanence and Anhysteretic States

Advanced Functional Materials, EarlyView.
A micrometric array of magnetic pillars provides a stable and unclonable hardware for generating cryptographic keys. From a single device, the ability is demonstrated to produce a 470‐bit key while also offering a reconfigurable mode of operation.

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

Advanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Tracking the Dynamic and Interactive Metal Oxidation Changes in CoFe, CoNi, and NiFe Bimetallic Hydroxides for Electrocatalytic Oxygen Evolution

Advanced Functional Materials, EarlyView.
Operando hard X‐ray absorption spectroscopy is applied to track the dynamic and interactive metal oxidation changes in iron group bimetallic hydroxides under different chemical and electrochemical conditions. It shows that Co and Fe oxidation are relatively equal and synchronized in CoFeOxHy.

Boundary differentiability for inhomogeneous infinity Laplace equations

Electronic Journal of Differential Equations, 2014
We study the boundary regularity of the solutions to inhomogeneous infinity Laplace equations. We prove that if $u\in C(\bar{\Omega})$ is a viscosity solution to $\Delta_{\infty}u:=\sum_{i,j=1}^n u_{x_i}u_{x_j}u_{x_ix_j}=f$ with $f\in C(\Omega)\cap L^
