Laser‐Textured Field‐Engineered Interface for Robust Dry‐Processed Cathodes in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Laser‐patterned dry electrodes applied to current collectors could serve as a promising alternative to the limitations of conventional dry electrodes. Laser technology provides a fast and simple method to enhance the surface roughness of current collectors, improving the adhesion at the electrode–current collector interface.

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Defining sagittal knee phenotypes via monopedal static anterior tibial translation. Part 1: Translating weight‐bearing sagittal position into clinical risk profiles

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Static anterior tibial translation (sATT) is a reproducible monopodal weight‐bearing radiographic parameter that reflects the resting sagittal position of the tibiofemoral joint. Distinct from manual laxity tests that quantify passive displacement limits, sATT captures the functional equilibrium of the tibia under physiological load ...

Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

Polymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...
