Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures
Advanced Functional Materials, EarlyView.Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating
Advanced Materials, EarlyView.This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.

Property Optimization of Al-5Si-Series Welding Wire via La-Ce-Ti Rare-Earth Microalloying
CrystalsThe 6xxx-series Al alloys have been used for decades because of their favorable strength-to-weight ratio, corrosion resistance, and fatigue performance. However, conventional welding techniques often induce localized weakening, as thermal effects modify ...

Assessment of the hardness of S890QL material welded joins [PDF]
Journal of Research and Innovation for Sustainable SocietyThe need to reduce the mass of products manufactured by welding processes has led to the replacement of the basic steel materials, such as construction steels, by steels with high mechanical properties, such as hard and brittle steels.

Advanced Materials, EarlyView.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Numerical evaluation of the weldability of the low alloy ferritic steels T/P23 and T/P24
Materials Research, 2011 A model based on transport equations was numerically implemented by the finite volume method (FVM) in a computational code in order to simulate the influence of the heat input, base metal thickness and preheating temperature on the thermal evolution and ...

Study of the Heat-Treatments Effect on High Strength Ductile Cast Iron Welded Joints
Metals, 2017 Nowadays, ultimate tensile strengths above 400 MPa become usual for ductile irons, thus allowing the implementation of new design paradigms. Large concentrations of carbon and other influencing elements can negatively interfere with the welding process ...

Electrically weldable conductive elastomers
Science AdvancesFlexible and stretchable electronic devices are subject to failure because of vulnerable circuit interconnections. We develop a low-voltage (1.5 to 4.5 V) and rapid (as low as 5 s) electric welding strategy to integrate both rigid electronic components and soft sensors in flexible circuits under ambient conditions.
