Soil–Water–Air (SWA) Interface Channel Model for River Bridge Pillar Health Monitoring Using WSN

open access: yesInformation
Wireless sensor networks are installed beneath the earth’s surface to track and assess the condition of the below-ground structures. In these systems, buried sensor nodes identify structural anomalies and transmit the sensed information through both soil

Surprising Water Slipping Performance on Highly Hydrophilic PEG‐Derived Monolayer‐Covered Surfaces: Preparation, Mechanism, and Application

open access: yesAdvanced Functional Materials, EarlyView.
Highly hydrophilic surfaces (water contact angle, ≈17.7°) exhibiting surprising water slipping performance (sliding angle, ≈7.3°) are successfully prepared via simple chemisorption of polyethylene glycol (PEG) organosilane and subsequent alkali‐treatment.

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

open access: yesAdvanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...
