Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Order Norm Completions of Cone Metric Spaces

open access: yesNumerical Functional Analysis and Optimization, 2011
In this article, a completion theorem for cone metric spaces and a completion theorem for cone normed spaces are proved. The completion spaces are constructed by means of an equivalence relation defined via an ordered cone norm on the Banach space E whose cone is strongly minihedral and ordered closed.

Cone Metric Spaces are usual Metric Spaces by a Renorming in the Banach Space

open access: yesJournal of Nonlinear Analysis and Application, 2016
In this paper, we will attempt to enforce the feeling that cone metric spaces are not real generalization of metric spaces, by a renorming of the Banach space. In specific, we can convert any strongly minihedral normal cone P to a normal cone with normal constant 1. Consequently, and due to this result, every cone metric space is really a metric space,

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

open access: yesAdvanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Remarks on Some Recent Fixed Point Results on Quaternion-Valued Metric Spaces

open access: yesAbstract and Applied Analysis, 2014
Very recently, Ahmed et al. introduced the notion of quaternion-valued metric as a generalization of metric and proved a common fixed point theorem in the context of quaternion-valued metric space.

Conformal Metallosaccharide Hybrid Films for Protecting Wood Surfaces From Environmental Damage

open access: yesAdvanced Functional Materials, EarlyView.
Ti‐ribose hybrid films fabricated by molecular layer deposition form a conformal and uniform coating on wood surfaces, which provides water repellence, dimensional stability, and resistance to acidic and alkaline environments, while preserving the natural appearance.

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

open access: yesAdvanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.

On Multivalued Contractions in Cone Metric Spaces without Normality

open access: yesThe Scientific World Journal, 2013
Wardowski (2011) in this paper for a normal cone metric space (X,d) and for the family 𝒜 of subsets of X established a new cone metric H:𝒜×𝒜→E and obtained fixed point of set-valued contraction of Nadler type.

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair

open access: yesAdvanced Healthcare Materials, EarlyView.
An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...

Integral Operators in b-Metric and Generalized b-Metric Spaces and Boundary Value Problems

open access: yesFractal and Fractional
We study fixed-point theorems of contractive mappings in b-metric space, cone b-metric space, and the newly introduced extended b-metric space. To generalize an existence and uniqueness result for the so-called Φs functions in the b-metric space to the ...
