Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

open access: yesAdvanced Functional Materials, EarlyView.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

On the Computational Complexity of Optimization Convex Covering Problems of Graphs [PDF]

open access: yesComputer Science Journal of Moldova, 2020
In this paper we present further studies of convex covers and convex partitions of graphs. Let $G$ be a finite simple graph. A set of vertices $S$ of $G$ is convex if all vertices lying on a shortest path between any pair of vertices of $S$ are in $S ...

Moduli of uniform convexity for convex sets

open access: yesArchiv der Mathematik
AbstractLet C be a proper, closed subset with nonempty interior in a normed space X. We define four variants of modulus of convexity for C and prove that they all coincide. This result, which is classical and well-known for $$C=B_X$$ C = B

Direct Laser Ablation of 2D Material Films for Fabricating Multi‐Functional Flexible and Transparent Devices

open access: yesAdvanced Functional Materials, EarlyView.
A scalable method for direct laser patterning of 2D films on transparent substrates like polycarbonate and glass is presented. This technique eliminates the need for photolithography and solvents, enabling the fabrication of functional devices like strain gauges, supercapacitors, and photodetector arrays.

Hyers–Ulam–Rassias Stability of Set Valued Additive and Cubic Functional Equations in Several Variables

open access: yesMathematics, 2019
In this paper, we establish Hyers−Ulam−Rassias stability results belonging to two different set valued functional equations in several variables, namely additive and cubic. The results are obtained in the contexts of Banach spaces.

Mechanisms of Anode Interfacial Phenomena and Multi‐perspective Optimization in Aqueous Alkaline Zinc‐Air Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Zinc‐air batteries demonstrate great potential for sustainable energy storage but face major anode‐related challenges. This review provides a mechanism‐driven overview of zinc anode interfacial issues, e.g. dendrite formation, passivation, self‐corrosion, and hydrogen evolution; and explores advances in electrode, surface, and electrolyte engineering ...

Unlock the Walnut: How a Pectin‐Rich Suture Tissue and Moisture‐Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

open access: yesAdvanced Functional Materials, EarlyView.
Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

Some Remarks on Smooth Mappings of Hilbert and Banach Spaces and Their Local Convexity Property

open access: yesAxioms
We analyze smooth nonlinear mappings for Hilbert and Banach spaces that carry small balls to convex sets, provided that the radii of the balls are small enough.

A *-mixing convergence theorem for convex set valued processes

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
In this paper the concept of a *-mixing process is extended to multivalued maps from a probability space into closed, bounded convex sets of a Banach space.
