Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Anterior Shoulder Instability Treated Through an Anterior Arthroscopic Approach

Arthroscopy Techniques, 2023
Anterior shoulder instability remains one of the main indications for shoulder surgery. We present a modified way of treating anterior shoulder instability in the beach-chair position from an anterior arthroscopic approach through the rotator interval ...

Si‐Doped Nanocrystalline Diamond as Highly Sensitive Luminescence Thermometer for the Physiological Temperature Range

Advanced Functional Materials, EarlyView.
In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.

Clinical Outcomes of Shoulder Stabilization in Females With Glenoid Bone Loss

Orthopaedic Journal of Sports Medicine, 2021
Background: Nearly all studies describing shoulder stabilization focus on male patients. Little is known regarding the clinical outcomes of female patients undergoing shoulder stabilization, and even less is understood about females with glenoid bone ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Diagnosis and treatment of posterior shoulder instability based on the ABC classification

EFORT Open Reviews
Posterior shoulder instability (PSI) is less common than anterior shoulder instability, accounting for 2–12% of total shoulder instability cases. However, a much higher frequency of PSI has been recently indicated, suggesting that PSI accounts for up ...

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

Advanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Band Alignment and Composition of the Buried TiO2/GaInP Interface

Advanced Materials Interfaces, EarlyView.
Buried TiO2$\text{TiO}_2$/GaInP interfaces formed by mild plasma‐enhanced ALD are shown to be largely insensitive to the initial GaInP surface condition. Angle‐dependent photoelectron spectroscopy reveals similar interfacial chemistry and band alignment for phosphorus‐rich and naturally oxidized surfaces, demonstrating a robust pathway for reproducible

Long-Term Outcomes following Instability After Isolated Arthroscopic Bankart Repair for On-Track Hill-Sachs Lesions With <20% Glenoid Bone Loss

Orthopaedic Journal of Sports Medicine
Background: Recurrent anterior shoulder instability rates are high after isolated arthroscopic Bankart repair (ABR), especially among patients with off-track Hill-Sachs lesions (HSLs) and significant glenoid bone loss.
