Summary: This study proposes a solution to the reduced thermal insulation performance caused by carbon nanotubes (CNTs) in composite insulation materials, by pre-coating the CNTs with a carbon layer. The experimental results show that the coated-CNTs formulation significantly reduces thermal conductivity and improves the char layer strength of the insulation material. Overall, the coated-CNTs not only enhance the thermal insulation performance by reducing thermal conductivity, but also improve particle erosion resistance by strengthening the char layer.

Summary: The structural and electronic properties of Zn-m@C-60 and Zn-m@C-70 endohedral metallofullerenes (m = 1-5) were investigated using DFT calculations. Despite having higher binding energies, these endohedral metallofullerenes are energetically stable. Encapsulating Zn-4 and Zn-5 clusters inside C-60 and C-70 fullerenes leads to structural transformations and electronic changes, improving their absorption of visible and ultraviolet light. These properties have potential applications in areas such as heavy metal encapsulation, electronic device design, gas sensors, and solar cells.

Summary: This study investigates the effect of an additional floating electrode on the properties of an atmospheric pressure plasma jet with a cross-field electrode configuration. The experiments show that the presence of an additional floating electrode reduces the power required for the plasma jet to cross the nozzle and increases the jet length. The threshold power and maximum jet length depend on the width of the electrode. The analysis also reveals an improvement in the reactivity of the plasma plume due to the increased optical emission intensity and relative yield of ions in the presence of the additional floating electrode.

Summary: Carbon nanofibers/tubes were successfully formed by catalytic cracking methane using Al2O3/KOH as the catalyst precursors. The effects of pyrolysis temperature and the molar ratio of Al2O3 to KOH on the growth of carbon nanofibers/tubes were investigated. The results showed that temperature and molar ratio significantly influenced the properties of the products, with the optimal temperature being 900 degrees Celsius for the production of carbon nanofibers/tubes with diameters ranging from 50 to 150 nanometers.

Summary: The catalytic activity of K10 montmorillonite during the CVD of carbon nanotubes was investigated, and the influence of free iron on CNT synthesis was studied. Before Fe removal, K10-Mt was covered with pyrolytic carbon deposits, while after purification, regular forms of CNT were formed. Multi-walled carbon nanotubes were observed on the surface of pure K10-Mt, and after extraction of free iron, nucleation sites for CNT growth were identified.

Summary: The spark plasma sintering technique improves the mechanical properties of TiB2-SiC ceramic by forming an interlocking structure. This study investigates the phase transition process of TiB2 powders with self-assembled structure and its effect on the mechanical properties of TiB2-based ceramics. The enhanced performance is attributed to the interlocking structure that effectively absorbs energy and facilitates crack deflection.

Summary: The Russian Federation's military operation against Ukraine primarily targets the European Union (EU) and the US due to their dependence on fossil fuel resources. The EU and Ukraine are the largest importers of Russian fossil fuels. This overreliance has led to a decrease in the EU's energy security index. To improve this, the EU has implemented energy bans in coordination with other countries. Upgrading the infrastructure at the regional level could enable the EU to be free of energy imports from Russia and achieve carbon neutrality by 2050.
