Summary: We demonstrate the synthesis of a solvent- and gas-free 2D carbon nanotube/graphene network through flash Joule heating of pristine carbon nanotubes. The proportion of each morphology in the hybrid material can be controlled by varying the pulse time. Epoxy composites made with the hybrid material show significantly increased hardness and Young's modulus compared to neat epoxy, indicating that flash Joule heating can effectively convert carbon nanotubes into a hybrid network for reinforcement.

Summary: A comprehensive understanding of the electrothermal characteristics and phenomena of nanocarbon aerogels is essential for optimizing their Joule-heating performance and expanding their applications. This study investigates the impact of density on Joule heating by examining reduced graphene oxide aerogels and reduced graphitized nanofiber aerogels with different densities. The results show that aerogels with higher densities exhibit improved electrical and thermal conductivities, while low-density aerogels have more pronounced heating features and efficiency, making them suitable for energy-efficient applications. Regardless of density variations, all the fabricated aerogels display efficient electron hopping, enabling uniform resistive heating throughout the aerogel structure.

Summary: This paper presents a method for 3D printing self-heating structures by embedding conductive layers in a thermoplastic matrix using a dual-nozzle setup. The method utilizes a suspension of carbon nanotubes and short carbon fibers, which form a thin conductive film after the solvent evaporates. The resistive heater embedded in the structure can generate temperatures up to 200 degrees C and can be controlled by adjusting electrical parameters and modifying the suspension. The results demonstrate that 3D-printed self-heating structures offer better design and multi-material capabilities compared to traditional manufacturing methods, while maintaining Joule heating performance.

Summary: Nanoporous silver films (npAgF) can be fabricated using plasma treatments, which offer a simpler and greener approach compared to traditional methods. A wrinkled npAgF (w-npAgF) was successfully prepared using a thermally contractible polystyrene substrate, and it showed significantly higher SERS enhancement compared to flat npAgF. The w-npAgF could be reused for multiple SERS measurements after mild plasma treatments, demonstrating its potential as a low-cost and reusable 3D SERS substrate.

Summary: This paper presents a fast and environmentally friendly method to activate carbon fibers (CFs) using a one-step joule-heating process. The activated CFs exhibit a hierarchically porous structure and exfoliated surface layers. As a fiber electrode, it shows a specific capacitance of 162 F g-1, which is 125 times higher than that of non-activated CFs. Furthermore, the joule-heating activation promotes the growth of foreign components on the fiber surface and enhances their interfacial interaction.

Summary: By controlling electrochemical dealloying, we modified the ligament surface of nanoporous gold (NPG) to improve its surface-enhanced Raman scattering (SERS) property. The presence of high-density atomic steps and kinks on the curved surfaces, as well as high-content silver atoms close to the ligament surface, contributed to the high SERS ability. This strategy is important for the fabrication of nanoporous metals with excellent surface properties for sensing, conversion, and catalysis.

Summary: Neuroinflammation is crucial in neurological disorders, and its impact on electrophysiological activity can be studied using in vitro models. This study utilized a tri-culture of rat neurons, astrocytes, and microglia to investigate the effect of microglia on neural function and response to neuroinflammatory stimuli. The results showed that the tri-culture provided a better representation of the in vivo rat cortex and captured electrophysiological manifestations of neuroinflammation. This technology is expected to aid in understanding various brain disease mechanisms.
