An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)

open access: yesThe Anatomical Record, EarlyView.
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

A Faraday Cage‐Inspired Triboelectric Nanogenerator Enabled by Alloy Powder Architecture for Self‐Powered Ocean Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A Faraday cage‐inspired triboelectric nanogenerator (FC‐TENG) is developed using a FeCoCrNiAl alloy powder interface that confines electrostatic fields and suppresses charge dissipation. The resulting device achieves high‐voltage output (1276.27 V), strong humidity resistance, and excellent durability, enabling stable energy harvesting in ocean ...
