Summary: Researchers have statistically verified the chirality distribution of 413 individual as-grown single-walled carbon nanotubes using broadband Rayleigh spectroscopy. The results show an increasing trend in chirality distribution with a distinct anomaly at approximately 20 degrees, which can be explained by the influence of armchair-shaped site configurations at the catalyst-nanotube interface growth rate.

Summary: In carbon nanotube growth, approximately half of them grow at a constant rate, while the other half exhibit stochastic changes in growth rates or switches between different states. Statistical analysis reveals that the growth rate of a given nanotube essentially varies between two values, regardless of whether the rate change is accompanied by a change in chirality.

Summary: This paper demonstrates the possibility of MWCNT growth on initially amorphous Co-Zr-N-O alloy thin film, and discusses the details of the growth process. It was found that the growth of carbon nanotubes strongly depends on the Co concentration in the alloy film, and the presented technique can be used in the preparation of new advanced engineering materials.

Summary: This article proposes a universal kinetic model to solve the contradictory reports on the growth kinetics of carbon nanotubes. The model is quantitatively verified through experiments. The findings not only resolve discrepancies existing in the literature but also offer rational strategies to control the chirality, length, and density of nanotube arrays for practical applications.

Summary: This study reports a ferrocene polymer electrode prepared through chemical methods, which enables highly efficient and selective recovery of phosphate ions from wastewater. The unique structure and high conductivity of the electrode, as well as the integration of ferrocene and an amide bond, contribute to enhanced charge transfer and strong hydrogen bonding interaction with phosphate ions, leading to almost 100% selectivity.

Summary: Aerosol chemical vapor deposition (CVD) is an advanced technique for the production of single-walled carbon nanotubes (SWCNTs), but scaling up the CVD reactor is often limited by the difficulty in tracking the nanotube growth kinetics. In this study, the analysis of the SWCNT film equivalent sheet resistance (R90) versus residence time (tau) was used to assess the nanotube growth kinetics and reveal the mechanisms behind the effect of CO2 on catalyst deactivation rate.

Summary: CO2, a greenhouse gas emitted due to the extensive use of fossil fuels, is being mitigated through methods like carbon capture and storage. Converting CO2 into carbon nano-materials and hydrocarbons is a current research focus, but the high bond energy and technological difficulties in gas separation pose challenges.

Summary: Studying the nucleation and dynamic evolution of nanocrystals is crucial for their use as catalytic materials. For intermetallic nanocrystals, their catalytic performance is closely related to their unique geometrical and electronic structures. However, there is currently a lack of understanding about how intermetallic nanocrystals nucleate and evolve under harsh synthesis conditions. In this study, by regulating the nucleation and growth processes, twinned Pt2Mo intermetallic nanocrystals were successfully prepared. The results showed that the heating rate and annealing time played key roles in the formation of twinned interfaces. Furthermore, the study also revealed the unfavorable effect of long-term annealing on twinned nanoparticles, as they transformed into untwinned Pt2Mo nanoparticles. These findings are important for designing catalyst interface structures at the atomic level.

Summary: By introducing nonionic surfactant into the typically employed mixture of anionic surfactants, the aqueous two-phase extraction (ATPE) method can be enhanced for the straightforward isolation of (6,4) single-walled carbon nanotubes (SWCNTs) in one step. Thorough analysis of the parameter space by experiments and modeling reveals the underlying interactions between SWCNTs, surfactants, and phase-forming agents, which drive the partitioning. A separation mechanism is proposed based on the new insight gained.

Summary: In order to meet the demands of future nanoelectronic applications, single-walled carbon nanotubes (SWCNTs) with specific electrical types are urgently needed. This study proposes a new multicycle approach to directly synthesize semiconducting SWCNTs (s-SWCNTs) with improved purity and yield using Fe0.01Mg(0.99)O as catalyst regeneration host. The selective synthesis of s-SWCNTs through this new multicycle growth process has an abundance of up to 93.2% and improves the yield of SWCNTs from 0.76% to 1.34%.

Summary: This study investigates the structural, microstructural, and magnetic properties of carbon nanotubes with magnetic iron carbide nanoparticles attached to their walls. The samples were fabricated using a modified CVD method, resulting in carbon nanotubes with iron carbide nanoparticles partially immersed in their walls. The magnetic nanoparticles exhibit a ferromagnetic behavior with high magnetic saturation due to their morphological characteristics and location on the walls of the nanotubes.

Summary: A new method for fabricating saturable absorbers for ring fiber lasers has been developed, utilizing fiber couplers and microfiber tapers coated with carbon nanotubes. It was demonstrated that the transmittance of the saturable absorber increases with input radiation power, enabling the generation of picosecond soliton pulses in a ring fiber laser configuration.
