In Situ Formation of Mechanically Interlocked Heterointerfaces with Ultrahigh Bonding Strength for Mg‐Based Multilayered Sheets

Advanced Science, EarlyView.
Crystal‐orientation controlled hot‐rolling strategy creates Mg‐Ta immiscible composites featuring mechanically interlocked in situ formed interfaces (80.5 MPa bond strength) and excellent tensile properties (340–395 MPa UTS). Systematic multiscale investigations reveal a serration‐size‐dependent bonding mechanism and a three‐stage interfacial evolution

Effect of Added Ni Nanoparticles on the Microstructure and Mechanical Properties of Sn58Bi/Cu Solder Joints under Thermal Shock Conditions

Advanced Electronic Materials, EarlyView.
This article concludes that the microstructure as well as grain coarsening is suppressed and the growth of IMC layer is promoted in Sn58Bi/Cu solder joints versus Sn58Bi‐0.6 Ni/Cu solder joints after 1200 thermal shock experiments, while the mechanical properties of the solder joints are improved.

Avoided energy cost of producing minerals: The case of iron ore

Energy Reports, 2019
There is growing concern about the decline of the ore grade in mines and the increased energy usage for processing and refining metals. In the limit, where no concentrated deposits exist, minerals must be obtained from bare rock.

Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.
