Mathematical and numerical analysis for Predator-prey system in a polluted environment

open access: yesNetworks & Heterogeneous Media, 2010
In this paper, we prove existence results for a Predator-prey system in a polluted environment. The existence result is proved by the Schauder fixed-point theorem. Moreover, we construct a combined finite volume - finite element scheme to our model, we establish existence of discrete solutions to this scheme, and show that it converges to a weak ...

Direct Ink Writing of Conductive Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Soliton Solutions and their (In)stability for the Focusing Davey-Stewartson II Equation [PDF]

open access: yesarXiv, 2016
We give a rigorous mathematical analysis of the one-soliton solution of the focusing Davey-Stewartson II equation and a proof of its instability under perturbation. Building on the fundamental perturbation analysis of Gadyl'shin and Kiselev, we verify their Assumption 1 and use Fredholm determinants to globalize their perturbation analysis.

Internal Temperature Evolution Metrology and Analytics in Li‐Ion Cells

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the non‐linear evolution of internal temperatures across diverse operating conditions, highlighting the disparities between internal and external measurements and the resulting thermal asymmetries. The coupled thermo‐electrochemical modeling framework provides a comprehensive analysis of various heat generation modes, examining ...

Al₂O₃‐Functionalized Carbon Nanomembranes with Enhanced Water Permeance and Selectivity for Efficient Air Dehumidification

open access: yesAdvanced Functional Materials, EarlyView.
Carbon nanomembranes with ultra‐thin Al2O3 functionalization are less than 15 nm thin and exhibit outstanding permeation performance with a water vapor/nitrogen selectivity higher than 1 × 104, twice that of pristine CNMs, and an exceptionally high water vapor permeation rate for potential applications in air dehumidification.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.
