A New 3D Colon on a Chip to Decipher the Influence of Mechanical Forces on the Physiological Cellular Ecosystem

open access: yesAdvanced Healthcare Materials, EarlyView.
To dissect how mechanical forces influence intestinal physiology, we developed a stretchable 3D colon‐on‐chip that integrates tunable topography, stiffness and peristalsis‐like motion within a physiologically relevant microenvironment. We showed that stretching is a dominant factor governing epithelial behavior, markedly enhancing proliferation and ...

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

open access: yesAdvanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...

On the Stiffening Effect of Hat-Shaped Stiffeners on a Plate

open access: yesJournal of the Society of Naval Architects of Japan, 1978
The object of this research is to clarify the stiffening effect of relatively large-sized hat-shaped stiffeners on a plate which are often utilized in FRP ship constructions. In the previous reports, both the bending and buckling deformation of a fundamental single stiffener model was described and it was shown that the lower width of a hat-shaped ...

Additive Manufacturing of Molecular Architecture Encoded Stretchable Polyethylene Glycol Hydrogels and Elastomers

open access: yesAdvanced Materials, EarlyView.
Bottlebrush molecular architecture prevents the crystallization of high molecular weight polyethylene glycol (PEG) based polymers, enabling highly stretchable photocurable PEG hydrogels and elastomers for high‐performance conductive solvent‐free electrolytes at room temperature and for additive manufacturing of complex architectures and multi‐material ...

Dynamic, Reconfigurable, and Hierarchical Biosynthetic Composites via Collagen Self‐Assembly within Highly Crowded Microgel Pastes

open access: yesAdvanced Materials, EarlyView.
A new approach to extracellular matrix‐mimetic, hierarchical biomaterials is presented. Soft gels composed of overpacked hydrogel microparticle arrays present a biomolecularly crowded environment permissive to the self‐assembly of collagen networks.

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

open access: yesAdvanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

Free and Forced Vibration Characteristics of a Composite Stiffened Plate Based on Energy Method

open access: yesJournal of Marine Science and Engineering
The composite stiffened plate has garnered significant attention in the lightweight design of ship structures due to its superior mechanical properties. Although it reduces the structural weight, it also increases vibration sensitivity.
