A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

Advanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

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‐

Wear Analysis of Second-generation Highly Cross-Linked Polyethylene in Primary Total Hip Arthroplasty.

, 2016
A major limiting factor in the longevity of total hip replacement is the wear rate of the hip bearing. As manufacturing technology has improved during the past several decades, much attention has been focused on developing newer generations of ...

Total hip replacements with metal-on-polyethylene bearings

Zdravniški Vestnik, 2009
Introduction: Polyethylene has been used as a bearing material for more than fi ft y years. It represents a golden standard in orthopaedics. Today the most important processes for manufacture of polyethylene are compression moulding and ram extrusion. As

Enhancing the Tribological Properties of Bearing Surfaces in Hip Arthroplasty by Shot-Peening the Metal Surface

Lubricants
Total hip arthroplasty (THA) is a surgical procedure for patients with pain and difficulty walking due to hip osteoarthritis. In primary THA, the acetabulum and femoral head are replaced by a prosthesis where the modular femoral head and inner liner of ...

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 ...

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...
