Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Flexible Tactile Actuator Arrays With Integrated Electroosmotic Pumps for Wearable Haptic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
1 ×$\times$ 9 and 4 ×$\times$ 4 flexible tactile actuator arrays integrating electroosmotic pumps are developed to deliver pressure and vibration feedback on wearable platforms. Their thin, compliant structure conforms seamlessly to curved body surfaces, providing intimate contact and enhanced haptic sensations.

Tetrapod Footprints From the Upper Carboniferous of China

Ichnos, 2010
We documented tetrapod footprints from Baode, Shanxi, China identified as aff. Dimetropus. These are the first record of carboniferous tetrapods from what was the North China block, a microplate isolated from the Pangean nucleus during the Carboniferous.
