Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

Advanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

Evaluation of ground and building settlement near braced excavation sites by model testing

, 2001
Braced excavations inevitably result in deformation of the adjacent ground and settlement of adjacent buildings behind the wall. Building settlement is believed to exceed the amount of associated ground settlement because of the additional settlement ...

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

Advanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

Trade dispute settlement mechanisms: the WTO dispute settlement understanding in the wake of the GATT [PDF]

A critical feature of the GATT Uruguay Round negotiations was the establishment of a new and more effective system of dealing with international trade disputes, known as the WTO Dispute Settlement Understanding (DSU). The original GATT dispute settlement

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

Advanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Settlement early warning method for high speed railway subgrades based on TD Transformer

Scientific Reports
During high speed railway construction, shield-tunnel undercrossing frequently induces subgrade settlement, which threatens project safety and progress. Existing settlement monitoring methods struggle to provide timely early warnings due to unclear data ...
