In the face of advancements in microrobotics, intelligent control and precision medicine, artificial muscle actuation systems must meet demands for precise control, high stability, environmental adaptability and high integration miniaturization. Carbon materials, being lightweight, strong and highly conductive and flexible, show great potential for artificial muscles. Inspired by the butterfly's proboscis, we have developed a carbon-based artificial muscle, hydrogen-substituted graphdiyne muscle (HsGDY-M), fabricated efficiently using an emerging hydrogen-substituted graphdiyne (HsGDY) film with an asymmetrical surface structure.

In this study, we investigate a novel hybrid borocarbonitride (bpn-BCN) 2D material inspired by recent advances in carbon biphenylene synthesis, using first-principles calculations and semi-classical Boltzmann transport theory. Our analysis confirms the structural stability of bpn-BCN through formation energy, elastic coefficients, phonon dispersion, and molecular dynamics simulations at 300 K and 800 K. The material exhibits an indirect band gap of 0.

Article Synopsis
- The study highlights the impressive lithium ionic conductivity achieved using graphene oxide laminar membranes, which significantly exceeds that of traditional lithium-ion electrolytes.
- At 170 mS cm, the nanoconfined lithium electrolyte demonstrates extraordinary performance, maintaining useful conductivity even at extremely low temperatures.
- The findings suggest that the enhanced ion transport is due to unique layer distribution effects in the nanochannels, potentially revolutionizing energy storage technologies by integrating these channels into lithium battery components.
