A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects

Advanced Science, EarlyView.
Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

Tribological Properties of Structural Ceramics [PDF]

, 1989
The tribological and lubricated behavior of both oxide and nonoxide ceramics are reviewed in this chapter. Ceramics are examined in contact with themselves, other harder materials and metals. Elastic, plastic and fracture behavior of ceramics in solid state contact is discussed. The contact load necessary to initiate fracture in ceramics is shown to be

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

The Importance of Fiber Orientation for the Performance of High-Performance Polymer-Based Hybrid Materials in Sliding Contact with Steel

Lubricants
The properties of composite materials depend not only on the composition but also on the distribution and orientation of the fillers, i.e., on the internal material architecture.

Restoring joint homeostasis: A dynamically adaptive meniscal scaffold prevents osteoarthritis by replicating native biomechanics

BMEMat, EarlyView.
This work establishes a paradigm shift from static structural mimicry to dynamic functional replication. By restoring the native “compression‐to‐tension” mechanism, the scaffold ensures robust mechanical stability and superior chondroprotection.

Fundamental Tribological Properties of Ceramics [PDF]

, 2008
When a ceramic is brought into contact with itself, another ceramic, or a metal, strong bond forces can develop between the materials. Adhesion between a ceramic and itself or another solid are discussed from a theoretical consideration of the nature of the surfaces and experimentally by relating bond forces to the interface resulting from solid state ...
