Chemically Reactive Thin Films: Dynamics and Stability

Advanced Materials Interfaces, EarlyView.
What happens to a thin liquid film when chemical reactions occur inside it? By means of theoretical analysis, it is showed that such systems (which are very common in heterogeneous catalysis) become very dynamic and not only their wetting properties are strongly affected by the chemical activity, moreover their interface can undergo traveling and ...

Borophene‐Based Ultrasensitive and Broadband Photodetectors

Advanced Materials Interfaces, EarlyView.
The direct growth of χ3‐phase borophene on n‐type silicon wafers leads to superior Schottky junctions, making them ideal for broad‐range, high‐sensitivity photodetectors. These photodetectors demonstrate higher sensitivity and faster response times compared to those fabricated by transferring 2D materials onto silicon to form van der Waals junctions ...

Reduction of weakly nonlinear parabolic partial differential equations [PDF]

Journal of Mathematical Physics, 2013
It is known that the Swift-Hohenberg equation \documentclass[12pt]{minimal}\begin{document}$\partial u/\partial t = -(\partial _x^2 + 1)^2u + \varepsilon (u-u^3)$\end{document}∂u/∂t=−(∂x2+1)2u+ɛ(u−u3) can be reduced to the Ginzburg-Landau equation (amplitude equation) \documentclass[12pt]{minimal}\begin{document}$\partial A/\partial t\break = 4\partial

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

Advanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...

Time‐ and Frequency‐Domain THz Imaging for the Characterization of Subwavelength Tags in Anticounterfeiting Devices

Advanced Materials Technologies, EarlyView.
Anticounterfeiting optical devices typically rely on random surface patterns revealed under IR/vis/UV light. Despite its security, this method suffers from the unavoidable deterioration of exposed superficial patterns. The proposed technique utilizes the high penetration depth and resolution of THz radiation to reveal submillimeter metallic patterns ...

Bayesian Parameterization of Continuum Battery Models from Featurized Electrochemical Measurements Considering Noise**

Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
We introduce a computer algorithm that incorporates the experience of battery researchers to extract information from experimental data reproducibly. This enables the fitting of complex models that take up to a few minutes to simulate. For validation, we process full‐cell GITT measurements to characterize the diffusivities of both electrodes non ...

Existence of solutions for a degenerate seawater intrusion problem

Electronic Journal of Differential Equations, 2005
We study a seawater intrusion problem in a confined aquifer. This process can be formulated as a coupled system of partial differential equations which includes an elliptic and a degenerate parabolic equation.

A Two-Dimensional Nonlocal Fractional Parabolic Initial Boundary Value Problem

Axioms
In this paper, we investigate a two-dimensional singular fractional-order parabolic partial differential equation in the Caputo sense. The partial differential equation is supplemented with Dirichlet and weighted integral boundary conditions.

Nonlinear functional integrodifferential equations in Hilbert space

International Journal of Mathematics and Mathematical Sciences, 1999
Let X be a Hilbert space and let Ω⊂Rn be a bounded domain with smooth boundary ∂Ω. We establish the existence and norm estimation of solutions for the parabolic partial functional integro-differential equation in X by using the fundamental solution.

Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits

Advanced Materials Technologies, EarlyView.
This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or
