Summary: Carbon nanotubes (CNTs) have attracted significant interest as functional materials due to their exceptional mechanical, electrical, thermal, and photoelectric properties. However, the strong Van der Waals force causes CNTs to agglomerate into crystalline bundles, hindering their potential applications. Effective dispersion strategies, such as covalent and non-covalent functionalization, have been proposed to overcome this challenge and improve the self-assembling characteristics of CNTs. Non-covalent modifications, including electrostatic interaction, 7C-7C stacking interaction, dipole interactions, Van der Waals interactions, hydrogen bond, and coordination, are particularly attractive for CNTs dispersion without disturbing their internal electronic structure.

Summary: Plasma-catalytic pyrolysis is a promising technology for upgrading plastic waste and producing hydrogen and high-value carbon materials. This study investigated the role of plasma in the pyrolysis of polypropylene (PP) and found that plasma can further activate and cleave the pyrolysis volatiles, resulting in more active carbon species for the growth of carbon nanotubes (CNTs). Compared to conventional catalytic pyrolysis, plasma addition significantly reduced the formation temperature of CNTs and promoted the conversion of liquid and gaseous products to CNTs and hydrogen. The addition of plasma also improved the graphitization degree of CNTs and reduced their defectivity. The findings highlight the potential of plasma-catalytic pyrolysis for the valorization of plastic waste.

Summary: This study investigates the effect of an additional floating electrode on the properties of an atmospheric pressure plasma jet with a cross-field electrode configuration. The experiments show that the presence of an additional floating electrode reduces the power required for the plasma jet to cross the nozzle and increases the jet length. The threshold power and maximum jet length depend on the width of the electrode. The analysis also reveals an improvement in the reactivity of the plasma plume due to the increased optical emission intensity and relative yield of ions in the presence of the additional floating electrode.

Summary: Structural batteries made of carbon fiber composites have attracted significant attention in automotive applications. However, the electrolyte used in these batteries typically relies on highly volatile liquid electrolytes, which limits their performance. This study proposes a new type of structural battery electrolyte that is a two-phase system formed through reaction-induced phase transition. It combines a low flammability electrolyte with a solid additive to induce multihydrogen bonding. The optimized electrolyte demonstrates good ionic conductivity at ambient temperature and shows potential for application in carbon fiber composite structural batteries.
