Ultralight Soft Wearable Haptic Interface with Shear‐Normal‐Vibration Feedback
Advanced Intelligent Systems, EarlyView.This study proposes soft wearable haptic interface using pneumatic actuators and origami pumps. This interface can generate multiple sensations such as touching, slipping, and vibrating. To show performance and wearability of this interface, virtual reality is connected with the interface, and user tests are conducted.

Shaping the human face: Periosteal bone modeling across ontogeny
The Anatomical Record, EarlyView.Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

A Review of the Use of Chemical Stabilisation Methods for Lithium‐Ion Batteries
Battery Energy, EarlyView.The review reveals that while chemical stabilisation techniques for recycling EOL LIBs are widely used, many studies overlook safety risks, focusing on quick, low‐cost methods. Only a few studies address the associated hazards, highlighting the need for safer, well‐understood stabilisation processes in battery recycling. ABSTRACT The increasing amounts
