Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

Advanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Shoulder Hemiarthroplasty for Proximal Humerus Fracture

Journal of Orthopaedic Trauma, 2021
Summary: There are a variety of treatment options available for proximal humerus fractures, including nonoperative management, open reduction internal fixation with screws, locking plates, intramedullary nailing, or suture fixation, and arthroplasty, including hemiarthroplasty and total shoulder replacements.

Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

Advanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

The Floating Acromion: A Rare and Previously Unreported Injury Possibly Requiring Surgical Stabilization

Case Reports in Orthopedics, 2020
Acromion fractures are increasingly seen as a postoperative complication following reversed shoulder arthroplasty. However, traumatic fractures of the acromion, usually caused by direct trauma, are rare.

Shoulder arthroplasty for proximal humerus fractures in the elderly: The path from Neer to Grammont

Orthopedic Reviews, 2020
Shoulder replacement is indicated for the surgical treatment of proximal humeral fractures in elderly patients, when severe comminution and osteoporosis jeopardize the chances of success of any fixation technique. Two different implants are available for

Simultaneous bilateral traumatic clavicle fractures: incidence, characteristics, and surgical outcomes

BMC Musculoskeletal Disorders, 2023
Background Although clavicle fractures are common injuries in adults, simultaneous bilateral clavicle fractures are rarely reported. The present report describes 13 patients with simultaneous bilateral traumatic clavicle fractures who were treated with ...

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

Advanced 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.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

Advanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Intrathoracic fracture—Dislocation of the shoulder [PDF]

Journal of Clinical Orthopaedics and Trauma, 2018
Intrathoracic dislocation of the shoulder is a rare condition that usually occurs after high-energy trauma. Etiology, mechanism of injury and associated lesions are diverse. We present the case of a patient who suffered a great height fall, treated with removal of the humeral head and implantation of a shoulder hemiarthroplasty.
