Summary: This study experimentally investigated the rheology and viscosity of nanofluids containing SWCNT, showing that the fluid index decreased and the consistency factor increased with increasing concentration of SWCNT. The viscosity of the nanofluids depended on the effective size of SWCNTs, and they exhibited viscoelastic properties due to the formation of a solid spatial lattice of nanotubes.

Summary: This paper explores the growth mechanism, structure, growth processes, growth kinetics, and optical, vibronic and electronic properties of metallocene-filled single-walled carbon nanotubes (SWCNTs). The procedures used to fill the nanotubes are described. The doping effects on metallicity-mixed and sorted SWCNTs filled with metallocenes are investigated through various spectroscopy techniques. The modification of the electronic properties of filled SWCNTs and the applications of metallocene-filled SWCNTs in various fields are discussed.

Summary: Single-walled carbon nanotubes (SWCNTs) are considered a promising electronic material for the future of electronics, with sub-10 nm SWCNT-field effect transistors (FETs) outperforming Si-based FETs. Recent advances in SWCNT electronics focus on fundamental electronic structures, carrier transport mechanisms, and metal/SWCNT contact properties, highlighting subthreshold switching properties for low-power device operations. Challenges and prospects for future SWCNT-based electronics include material preparation, device fabrication, and large-scale ICs integration.

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.

Summary: This study investigates the electrostatic interactions of single-walled carbon nanotubes using electrostatic force microscopy. The results show that surfactant coverage on long nanotubes leads to nonuniform spatial charge distributions and the potential well depth can be estimated by charge densities, suggesting the localization of excitons.

Summary: We propose a facile, cost-efficient, environmentally friendly, and scalable process to renew single-walled carbon nanotube membranes serving as extreme ultraviolet (EUV) protective pellicles. The method involves high-temperature treatment of the membrane to clean it without damaging the carbon nanotube structure, opening up possibilities for multiple membrane renovations.

Summary: Despite the commercial availability of many different hydrogel formulations, the effective gel-based purification of single-walled carbon nanotubes (SWNT) remains exclusive to Sephacryl S-200. In this study, various commercially available gels and custom-synthesized gels were investigated for their ability to purify SWNT, with findings showing that different gels exhibit unique SWNT chiral selectivity and physiochemical properties. Superose 6 was found to adsorb more SWNT than Sephacryl S-200 and exhibit a unique preference for specific SWNT chiralities, providing insights into the rational design of gels for SWNT purification.

Summary: Cobalt sulfide catalysts supported on porous silica show potential for CNT synthesis, with their catalytic performance strongly influenced by reduction temperature and cobalt mass loading. The catalysts have demonstrated selectivity towards single-walled CNTs, but higher cobalt mass loading leads to the formation of multi-walled CNTs and graphite.
