Summary: In this paper, the authors use first-principles density functional theory calculations to show the conversion of AB or Bernal-type stacked armchair and AB' zigzag bilayered SiC nanoribbons into defect-free zigzag and armchair single-walled SiC nanotubes, respectively. The formation of closed nanostructures is facilitated by the establishment of interlayer bonds and the compensation of charges at their edges. The study also reveals the involvement of edge dynamics in the formation of SiCNTs and the feasibility of growing zz-SiCNTs compared to ac-SiCNTs. The dimension-dependent electronic properties of SiCNTs are investigated, showing that both types are semiconducting due to the disappearance of edge states.

Summary: The selective growth of semiconducting single-walled carbon nanotubes (s-SWCNTs) is achieved using CO as both catalyst reductant and carbon feedstock, along with bimetallic catalysts and quartz substrates. The CO-based process demonstrates feasibility and universality, resulting in horizontally aligned s-SWCNT arrays with high content (>97%) and potential for scalable fabrication of CNT-based devices.

Summary: Coaxial synthesis of single-walled and multiwalled molybdenum disulfide (MoS2) nanotubes on boron nitride nanotubes (BNNTs) was achieved by removing single-walled carbon nanotubes (SWCNTs) from heteronanotubes. Single-walled MoS2 nanotubes exhibit direct bandgap structure around 6-7 nm diameter, with a transition from indirect to direct gap above 5.2 nm. Presence of SWCNTs in BNNTs and single-walled MoS2 nanotubes significantly quenches the PL signal.

Summary: This study investigated the treatment of single-walled carbon nanotubes with strong HClO4 acid through experimental and computational analysis, showing significant changes in the behavior of metallic nanotubes and their conversion to semiconductors. The DFT calculations confirmed the experimental results by revealing the generation of an energy gap in the electronic structure of metallic carbon nanotubes due to the adsorption of chlorine atoms.

Summary: In this study, CuI@SWCNT networks were successfully prepared by filling CuI into SWCNTs. CuI@SWCNT networks exhibited good stability and significantly improved current carrying capacity and conductivity compared to SWCNTs. By regulating the Fermi level position of SWCNTs, CuI guest molecules increased carrier concentration, achieving high conductivity and high current carrying capacity. This study offers ideas and solutions for the regulation of high-performance carbon tube networks, which hold great promise for future applications in carbon-based electronic devices.

Summary: Multifunctional electrodes for structural supercapacitors were prepared by infiltrating single-walled carbon nanotubes (SWCNTs) into woven carbon fibers (CFs) using a vacuum method. The use of reductive charging chemistry ensured a high degree of individualization. The resulting electrodes showed high conductivity, surface area, and electrochemical performance, and significantly improved the electrical conductivity, surface area, and in-plane shear properties of the CF fabrics. Structural supercapacitors based on these electrodes exhibited high specific energy and power densities in the chosen electrolyte. This approach provides a new route to structural energy storage systems.

Summary: Carbon nanomaterials such as graphene and carbon nanotubes have attracted significant interest due to their extraordinary properties, with the potential to play a key role in future applications. The sensitivity of carbon nanostructures to chemical stimuli allows for enhanced charge propagation capabilities, as seen in the impact of bromine addition on the electrical and thermoelectric properties of single-walled carbon nanotube films. Experimental results show a two orders of magnitude enhancement in thermoelectric capabilities through sonication-assisted introduction of Br2 into the SWCNT network, with computational analyses revealing the dopant's influence on electronic and charge transport properties.
