Microscale Patterning of Ultrahigh‐Viscosity Metallic‐Polymer Composites via Embedded Droplet Writing

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid additive manufacturing platform integrates direct droplet writing of metallic composite with VAT photopolymerization to fabricate architected soft magnetic composites. This approach enables microscale patterning of high‐viscosity materials for programmable actuators, adaptive fluidic devices, and switchable adhesives, offering tunable ...

Minimal Wave Speed in an Integrodifference System of Predator-Prey Type

open access: yesDiscrete Dynamics in Nature and Society, 2020
This article studies the minimal wave speed of traveling wave solutions in an integrodifference predator-prey system that does not have the comparison principle. By constructing generalized upper and lower solutions and utilizing the theory of asymptotic

An Overlooked Transport Mechanism in Organic Mixed Conductors

open access: yesAdvanced Functional Materials, EarlyView.
Electrical transport in organic mixed ionic‐electronic conductors is commonly described by ionic and electronic conduction. Here, eumelanin reveals that polarization‐assisted displacement currents constitute an additional transport component that coexists with conductive transport.

Modelling the biological invasion of Carcinus maenas (the European green crab)

open access: yesJournal of Biological Dynamics, 2016
This paper proposes a system of integro-difference equations to model the spread of Carcinus maenas, commonly called the European green crab, that causes severe damage to coastal ecosystems. A model with juvenile and adult classes is first studied. Here,

Advection and dispersion of bed load tracers [PDF]

open access: yesEarth Surface Dynamics, 2018
We use the erosion–deposition model introduced by Charru et al. (2004) to numerically simulate the evolution of a plume of bed load tracers entrained by a steady flow. In this model, the propagation of the plume results from the stochastic exchange of

On spreading sequences and asymptotic structures

open access: yes, 2018
In the first part of the paper we study the structure of Banach spaces with a conditional spreading basis. The geometry of such spaces exhibits a striking resemblance to the geometry of James space.

Tailored Cationic Visible‐Light‐Active Interfaces for Sustainable, Biodegradable Nanofibers With Dual‐Mode Antimicrobial Activity and Robust Electrostatic Particle Capture

open access: yesAdvanced Materials, EarlyView.
Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

Electrospun PCL Fibers Enhanced With Molecularly Imprinted Polymers for the Adsorption of Pharmaceutical Drugs

open access: yesAdvanced Materials Interfaces, EarlyView.
Electrospun polycaprolactone fiber mats embedded with diclofenac‐imprinted polymers were developed to remove persistent pharmaceutical pollutants from water. The materials showed improved adsorption and retention compared to pure polymer mats, with performance influenced by fiber diameter and polymer content.

Asymptotic spreading of predator-prey populations in a shifting environment

open access: yesMathematics in Applied Sciences and Engineering
Inspired by a recent study associating shifting temperature conditions with changes in the efficiency with which predators convert prey to offspring, we propose a predator prey model of reaction-diffusion type to analyze the consequence of such effects ...
