Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response

open access: yesAdvanced Functional Materials, EarlyView.
This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...

A necessary and sufficient condition for the existence of positive solutions to singular boundary-value problems of higher order differential equations

open access: yesElectronic Journal of Differential Equations, 2006
By constructing some special cones and using fixed point theorem of cone expansion and compression, this paper presents some necessary and sufficient conditions for the existence of $C^{4n-2}$ positive solutions to a class of singular boundary-value

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

open access: yesAdvanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

Three positive solutions for a system of singular generalized Lidstone problems

open access: yesElectronic Journal of Differential Equations, 2009
In this article, we show the existence of at least three positive solutions for the system of singular generalized Lidstone boundary value problems $displaylines{ (-1)^m x^{(2m)}=a(t)f_1(t,x,-x'',dots,(-1)^{m-1}x^{(2m-2)},y,-y'',cr dots,(-1)^{n-1}y^{

Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Positive periodic solutions of neutral functional differential equations with a parameter and impulse

open access: yesElectronic Journal of Differential Equations, 2008
In this paper, we consider first-order neutral differential equations with a parameter and impulse in the form of $$displaylines{ frac{d}{dt}[x(t)-c x(t-gamma)]=-a(t)g(x(h_1(t)))x(t)+lambda b(t) fig(x(h_2(t))ig),quad t eq t_j;cr Delta ig[x(t)-c x(t ...

Biomimetic Ion‐Orchestrated Hierarchical Armored Hydrogel Coating for Robust and Multifunctional Surface Protection

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by the skin‐toughening mechanism of marine sponges, an ion‐orchestrated structural engineering strategy is proposed to regulate the surface microstructure of hydrogel coatings, enabling the in situ formation of a robust armor layer that enhances mechanical integrity and provides multifunctional protection by suppressing fouling attachment and ...
