Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Self‐Assembly of a Colloidal Honeycomb Crystal in Silico for Topological Valley Photonics

Small, EarlyView.
The self‐assembly of a colloidal honeycomb crystal is demonstrated in computer simulations, using an assembly strategy that not only suppresses the formation of real‐space topological defects observed experimentally but also yields topological photonic properties in reciprocal space.

Synergic Magnetic–Dielectric Ni/Co‐Anchored Carbon Aerogels From Cellulose Nanofiber Scaffolds for Electromagnetic Shielding, Infrared Stealth, and Secure RFID Technologies

Small, EarlyView.
Ultralight Ni/Co‐anchored nanoporous carbon aerogels derived from TEMPO‐oxidized cellulose nanofibers integrate absorption‐dominated EMI shielding with infrared stealth. The hierarchical porous network provides dielectric/magnetic losses and suppresses thermal signatures.

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...
