Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures

Advanced Functional Materials, EarlyView.
In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Uniqueness of positive radial solutions for a class of $(p,q)$-Laplacian problems in a ball

Electronic Journal of Qualitative Theory of Differential Equations
We prove the uniqueness of positive radial solution to the $(p,q)$-Laplacian problem \begin{equation*} \left\{ \begin{aligned} -\Delta _{p}u-\Delta _{q}u={}&\lambda f(u)\quad \text{in }\Omega , \\ u={}&0\quad \text{on }\partial \Omega ,% \end{aligned}%

The positive radial solutions of a class of semilinear elliptic equations

This paper provides a complete classification of the positive radially symmetric solutions for generalized Emden equations of the type \[ \Delta u+r^{-2-\rho} h(r^{\rho} u)=0, \] where \(h(s)>0\) for \(s>0\) and \(h(0)=0\). The essential feature of these equations is that they can be transformed into autonomous equations.

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Radial bounded solutions for modified Schrodinger equations

Electronic Journal of Differential Equations
We study the quasilinear elliptic equation  $$ -\operatorname{div} (a(x,u,\nabla u)) +A_t(x,u,\nabla u) + |u|^{p-2}u =g(x,u) \quad \hbox{in }R^N, $$ with \(N\ge 2\) and \(p > 1\).

Spatially Regulated Silicon Clusters in Trimodal Composite Anodes for High‐Energy Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A trimodal anode architecture spatially regulates silicon clusters within confined interstitial environments formed by graphite and contorted hexabenzocoronene. This confinement suppresses silicon aggregation and localized stress while enabling efficient Li‐ion transport, achieving high‐capacity, stable lithium‐ion batteries.

Radial solutions of singular nonlinear biharmonic equations and applications to conformal geometry

Electronic Journal of Differential Equations, 2003
Positive entire solutions of the singular biharmonic equation $Delta^2 u + u^{-q}=0$ in $mathbb{R}^n$ with $q>1$ and $ngeq 3$ are considered. We prove that there are infinitely many radial entire solutions with different growth rates close to quadratic ...
