Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Analgesic application of a novel non-steroidal anti-inflammatory drug imrecoxib after total knee arthroplasty: a prospective randomized controlled study

Perioperative Medicine
Background Imrecoxib is a novel non-steroidal anti-inflammatory drug. As a moderately selective COX-2 inhibitor, it has achieved certain therapeutic effects in postoperative analgesia such as spinal, arthroscopic, and total hip arthroplasty. However, the

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

Advanced Functional Materials, EarlyView.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

The combination of a medial pivot design with kinematic alignment principles in total knee arthroplasty can ensure a closer to normal knee kinematics than combining mechanical alignment and more traditional implant designs: An umbrella review

Journal of Experimental Orthopaedics
Purpose The recent introduction of personalized alignment strategies in total knee arthroplasty (TKA) has transformed adult reconstruction. Proponents advocate for these techniques due to their kinematic benefits compared to traditional methods.

The Modified Trochleoplasty for Trochlear Dysplasia Types B and D

Arthroscopy Techniques
Trochlear dysplasia is a major risk factor for recurrent patellar instability, often requiring surgical intervention in high-grade cases. The present modified trochleoplasty technique, known as the “Brazilian trochleoplasty,” is a reproducible technique ...

Injectable Dual‐Network Hydrogel System for Osteochondral Repair Combining Immunomodulation, Mechanical Adaptability, and Enhanced Tissue Integration

Advanced Functional Materials, EarlyView.
A UV‐triggered injectable dual‐network hydrogel is reported as the first application of bletilla striata polysaccharide (BSP) in osteochondral repair. By integrating methacrylamide‐modified BSP and nitrobenzaldehyde‐functionalized hyaluronic acid, the system achieves immunomodulation, mechanical reinforcement, and dynamic tissue adhesion, thereby ...

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their
