Summary: Simple Walled Carbon Nanotubes (SWCNTs) were used as adsorbents to remove triclosan (TCS) from aqueous solution. The maximum adsorption capacity of TCS onto SWCNTs was found to be 30.3 mg g(-1) at a pH value of 7. The adsorption kinetics of TCS on SWCNTs was correctly interpreted by the First Order Kinetic Model and the Diffusional Model.

Summary: In this study, the plasmonic effects of Ag and Au nanoparticles with different geometries on the fluorescence intensity of single-stranded DNA-wrapped single-walled carbon nanotubes (ssDNA-SWCNTs) were systematically investigated. Chirality-dependent fluorescence enhancement was observed, which varied with nanoparticle shape and material. Au nanorods increased the fluorescence of (7, 5) and (7, 6) chiralities by 80% and 60% respectively, while Ag nano triangles increased the fluorescence of (7, 5) and (6, 5) chiralities by 200% and 240% respectively. Finite element modeling confirmed contributions from a plasmon-induced localized increase in electron density and radiative recombination of dark exciton states from the resulting electromagnetic field.

Summary: The probability of occupational exposure to carbon nanotubes (CNTs) is increasing due to their growing production and biomedical applications. As a result, the risk of co-exposure of nanomaterials with environmental pollutants is also increasing. This study investigated the toxicity of pristine single-walled CNTs (p-SWCNTs) and oxidized single-walled CNTs (SWCNT-COOHs) on cell responses to metal ions (Pb2+, Cu2+, and Cr(VI)). The findings suggest that understanding the effects of the exposure sequence of engineered nanomaterials and environmental pollutants on their toxicity is crucial for evaluating combined toxicity.

Summary: This study demonstrates the potential anti-inflammatory effect of poly-dispersed acid-functionalized single-walled carbon nanotubes in alleviating Mycobacterium bovis BCG-induced inflammatory responses in macrophages, mainly through inhibition of reactive oxygen species and nitric oxide production, decrease in pro-inflammatory gene expression, and reduction in matrix metalloproteinase release.

Summary: The development of a composite-type hybrid supercapacitor with high capacitance, specific energy, and long cycle life was achieved by using SWCNTs/TiO2 nanocomposite as electrodes and PVA/H2SO4 gel electrolyte. This work demonstrates that the hybrid electrochemical behavior of SWCNTs/TiO2 nanocomposite improves the overall supercapacitive performance, offering a promising route to develop high performance hybrid supercapacitors.

Summary: In this study, an effective method for controlling the viscosity of liquid crystal SWCNT phases was reported. By functionalizing single-walled carbon nanotubes, the viscosity and phase transformation of the liquid crystal phases could be precisely controlled. The resulting SWCNT fibers exhibited higher mechanical properties and electrical conductivity, as well as flexibility and durability for wearable and flexible electronic electrode devices. Moreover, the SWCNT fibers demonstrated excellent performance as Zn-ion supercapacitors with high capacitance retention after bending tests.

Summary: This study focuses on the elastic properties of non-carbon nanotubes based on compounds of the 13th group of the periodic table. The research reveals that these nanotubes are more suitable candidates than carbon nanotubes for building novel nano-devices, and proposes a robust methodology to calculate the surface elastic moduli of phosphide nanotubes.

Summary: In this study, a pH responsive optical probe comprised of Single-Walled Carbon Nanotubes (SWCNTs) in contact with a platinum redox couple (Pt-SWCNTs) was developed for accurate monitoring of pH in solutions. The probe demonstrated precise pH measurements across different ionic strengths, showing a strong Raman shift of the G-band as a function of pH. This work introduces an optical pH sensing scheme analogous to conventional pH sensors equipped with a built-in internal reference.

Summary: A facile method of functionalization of single-walled carbon nanotubes (SWNTs) with polypyrrole and making a chemiresistive sensor for sub-part-per-million detection of ammonia gas at room temperature was reported. The functionalized SWNTs showed higher sensitivity to ammonia gas, a wide measurable response range, good recovery of the sensor, and a relatively short response time.

Summary: Thermal conductivity of a suspended single-walled carbon nanotube (SWCNT) is significantly enhanced by introducing an axial tensile strain, and the enhancement is positively correlated with the strain magnitude. Furthermore, the reduction of thermal conductivity with temperature is alleviated for the strained nanotube compared to unstrained cases.

Summary: Single-walled carbon nanotubes (SWCNT) play a significant role in electromagnetic absorption and shielding, but are limited by 1/f noise. This research proposes a method to reduce the noise amplitude by treating SWCNT with nitric acid, which increases the resistance and decreases the excess carrier flow.
