Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer
Advanced Electronic Materials, Volume 11, Issue 6, May 2025.A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Optimization of sensitivity in Long Period Fiber Gratings with overlay deposition
Optics Express, 2005 The deposition of an overlay of higher refractive index than the cladding in a Long Period Fiber Grating (LPFG) permits to improve the sensitivity to ambient refractive index changes in a great manner. When the overlay is thick enough, one of the cladding modes is guided by the overlay.

Optimizing Anatomic Reduction of Vertical Meniscus Tears With All‐Inside Meniscus Repair
Arthroscopy Techniques, EarlyView.Abstract The lateral and medial meniscus play vital roles in load distribution across the knee joint and in the prevention of knee osteoarthritis. As such, every effort should be made to save and repair the meniscus when possible, as partial and total meniscectomies have been shown to impair the meniscus’ ability to effectively dissipate shock ...
