A review of friction stir-based techniques for magnesium alloys: Welding, processing, recycling, and additive manufacturing

Journal of Materials Research and Technology
Magnesium (Mg) alloys are increasingly vital in aerospace, automotive, electronics, and biomedical industries due to their high strength-to-weight ratio and recyclability. Conventional fusion-based methods often face limitations in joining and processing

Stress‐to‐Light Conversion in an Earth‐Abundant Oxide Semiconductor

Advanced Science, EarlyView.
Stress‐to‐light conversion in solids represents a unique photonic functionality, yet it has never been realized in a chemically simple and sustainable material. Here, we show that sustainable semiconductor ZnO exhibits strong near‐infrared (NIR) luminescence under elastic stress when defect‐engineered to stabilize the p‐type state.

Effect of Friction Stir Welding and Friction Stir Processing Parameters on The Efficiency of Joints

Al-Nahrain Journal for Engineering Sciences, 2018
Friction Stir Welding is one of the most practical welding process at the solid state. Friction Stir Processing is used to enhance the microstructure of FSW welded zone. The present study investigates the effect of welding parameters on the tensile properties   of FSW and FSP  joining 3 mm  AA 5083 - H111 aluminum alloy by means of  stress – strain ...

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

Advanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

Advanced Science, EarlyView.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...
