Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Stage‐Adaptive Janus Microneedle System for Redox‐Immune Regulation and Mitochondrial Protection in Infected Diabetic Wound Healing

Advanced Science, EarlyView.
ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...

Stress sensitivity analysis of vuggy porous media based on two-scale fractal theory

Scientific Reports
Interparticle pore space and vugs are two different scales of pore space in vuggy porous media. Vuggy porous media widely exists in carbonate reservoirs, and the permeability of this porous media plays an important role in many engineering fields. It has

Maximizing CO2 Accumulation in Storage Reservoirs: Interplay between Permeability Retardation and Capillary Trapping of Rising CO2

, 2017
SummaryThe main objective of this work is to understand, by analytical and numerical study, how permeability retardation interacts with capillary barrier trapping to cause accumulation as CO2 migrates upward in saline aquifers during geological ...

Study on the Influence of Sustained Axial Compression and Tension on the Permeability Properties of Panel Concrete

Buildings
The anti-seepage performance of concrete directly affects the anti-seepage effect and durability of the concrete face slab of the rockfill dam. Since the panel concrete is often in a complex stress state in practical engineering, its permeability ...

A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

Advanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Leg oedema—A diagnostic approach

Current Medicine Research and Practice, 2011
Oedema results from excess accumulation of interstitial fluid and produces palpable swelling. Its major causes include venous obstruction, increased capillary permeability, and increased plasma volume secondary to sodium and water retention.
