Simulación Numérica de Ondas Viajeras del Sistema FitzHugh-Nagumo

Selecciones Matemáticas, 2018
The FitzHugh-Nagumo system has a special type of solution called traveling wave, which has the form u(x, t) =f(x − μt) and w(x, t) =g(x − μt), which is a stable solution over time.

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

Advanced Materials, EarlyView.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation

Advanced Materials, EarlyView.
Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...

A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

Advanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

Traveling wave solutions for a neutral reaction–diffusion equation with non-monotone reaction

Advances in Difference Equations, 2019
In the present paper, we firstly improve the results on traveling wave solution that were established in (Liu and Weng in J. Differ. Equ. 258:3688–3741, 2015) for a neutral reaction–diffusion equation with quasi-monotone reaction.

FUNCTIONAL EXPANSIONS FOR FINDING TRAVELING WAVE SOLUTIONS

Journal of Applied Analysis & Computation, 2020
Summary: The paper proposes a generalized analytic approach which allows to find traveling wave solutions for some nonlinear PDEs. The solutions are expressed as functional expansions of the known solutions of an auxiliary equation. The proposed formalism integrates classical approaches as tanh method or \(G^{\prime}/G\) method, but it open the ...

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

Advanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

Advanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Entire solutions for a mono-stable delay population model in a 2D lattice strip

Electronic Journal of Differential Equations, 2014
This article concerns the entire solutions of a mono-stable age-structured population model in a 2D lattice strip. In a previous publication, we established the existence of entire solutions related to traveling wave solutions with speeds larger than ...
