Summary: The past two decades have seen significant progress in the catalytic synthesis of single-walled carbon nanotubes (SWNTs) using non-conventional nanoparticles. This study presents the use of a solid magnesia (MgO) supported ruthenium (Ru) catalyst for chemical vapor deposition (CVD) growth of SWNTs. The results show successful synthesis of enriched (6, 5) SWNTs at high temperatures, partially attributed to the high activity of Ru clusters. The study also reveals the mechanism behind the activation of Ru clusters through charge transfer from the MgO support.

Summary: Molecular dynamics simulations have shown the significant influence of hydration shells on ions passing through ultrathin carbon nanotubes. Electrically-driven ions tend to drag their hydration shells, while pressure-driven ions can be actively driven by their hydration shells. The different binding strengths of hydration shells to ions of various sizes affect the entry rates and driving speeds of ions in CNTs.

Summary: Porous conductive POE elastomeric composites were successfully fabricated with CNTs exclusively located in the PBAT phase. The fully exposed CNTs in the pores significantly increased electromagnetic interference shielding effects and conductivity by 11 orders of magnitude compared to the original ternary nanocomposites. This paves new possibilities for fabricating functional materials for flexible electronics.

Summary: In this study, a strategy utilizing oxygen vacancy concentration modulation was used to successfully grow semiconducting single-walled carbon nanotubes (s-SWCNTs) with narrow diameters. The Fe0.01Mg0.99O/CeO2(3) catalyst was employed to provide oxygen vacancies, allowing for selective etching of chemically active carbon nanotube caps during the growth process. The optimized conditions resulted in high purity s-SWCNTs with uniform diameters.

Summary: In this study, the impact of specific surfactant choice and concentration on ATP sorting was systematically investigated. The results revealed the influence of diameter-dependent stacking pattern on the separation order and the role of cosurfactants. These findings provide insights into predicting the parameters required for separating specific chiral structures in just two ATP steps.

Summary: The hydrogenation of CO2 enables the efficient utilization of renewable biogas by upgrading methane. This process has potential benefits for storage of renewable hydrogen energy and reduction of greenhouse gas emissions. A prototype reactor with double pass operation was used, along with an optimized Ni-Ce/Al-MCM-41 catalyst, to investigate the upgradation process. The results showed that the double pass operation significantly increased CO2 conversion and methane production yield, resulting in a higher purity of biomethane.

Summary: Doping porous carbons with palladium nanoparticles is known to enhance hydrogen storage capacity. Alloying palladium with copper can reduce cost and improve hydrogen adsorption properties. Formation of Cu mPdn nanoalloys is favorable, with some rich in copper showing higher adsorption binding energies than pure Pd-6, suggesting a way to enhance hydrogen adsorption in Pd-doped porous carbon materials.

Summary: This study investigates the effect of changing the relative concentration of two components in small Co-mAg-n nanoalloys on the adsorption and dissociation of molecular hydrogen. The results show that alloying can improve the efficiency of catalysts, and the adsorption and dissociation properties can be tuned by varying the relative composition of the two atomic species in the nanoalloy.

Summary: This study investigates the physisorption of N-2 and CO2 on carbon-based porous materials and the pore size distribution. By comparing the interaction energy curves obtained from different calculation methods with experimental results, it is found that double hybrid methods with dispersion corrections and omega B97-based DFT methods are accurate for benzene, while only the PBE-XDM functional shows good agreement with the Steele energy curves for graphene.

Summary: Metal clusters supported on carbonaceous substrates are studied in this paper for their structures and infrared spectra. The preferred clustering of Rh on the surface of the fullerene is observed, with electron transfer occurring from the metal cluster to the fullerene. Adsorption of Rh-n clusters leads to degeneracy lifting of the most intense C-60 features in the infrared spectra. The experimental and calculated spectra generally agree, except in the presence of D-2-messenger molecules in certain regions.

Summary: This study investigates the adsorption of hydrogen on graphdiyne (GDY) and boron-graphdiyne (BGDY) doped with palladium clusters using density functional calculations. The results show that Pd6 fits well on the large holes of GDY and changes its structure to a capped trigonal bipyramid structure in BGDY. Pd6GDY can adsorb up to five H2 molecules while Pd6BGDY can adsorb up to six molecules, with both having smaller dissociation barriers compared to undoped GDY and BGDY.
