Summary: Vertically aligned carbon nanotube (VACNT) arrays have superior vertical thermal conductivity but suffer from weak interaction between adjacent carbon nanotubes (CNT) during polymer infiltration. This study introduces a novel three-dimensional CNT (3DCNT) network structure, where VACNT is crosslinked by secondary CNT, to provide in-plane phonon paths and maintain structural stability. Results show that the 3DCNT20/P composite has significantly higher vertical and horizontal thermal conductivity compared to the IVACNT/P composite.

Summary: This study reports on the first macroscopic membranes with vertically oriented, subnanometer carbon nanotube (CNT) pores, which show enhanced water flow. The membranes, made using a scalable, solution-based method, exhibit fast pressure-driven water transport with up to 10^5-fold enhancement compared to conventional flow. The results also show that the hydrodynamic slip lengths increase with decreasing nanotube diameter, suggesting that water transport in small-diameter CNTs is dominated by entrance resistance.

Summary: A simple and cost effective method was developed to grow a 2.6 mm long vertically aligned carbon nanotube (VACNT) forest without using etchants or other complicated systems. By reducing the catalyst at lower temperature and using low carbon feedstock, dense and uniform nanoparticles formation was achieved, extending the catalyst NP lifetime. Additionally, the time varying forest height of VACNT was accurately represented by the Gompertz model due to low temperature catalyst reduction, enabling a cost effective and eco-friendly synthesis.

Summary: In this study, the electronic and magnetic properties of sulfur-doped highly-oriented-pyrolytic-graphite (HOPG) lamellae were investigated. The sulfur-doping process caused amorphization within hexagonal moire superlattices. Raman spectroscopy analysis revealed a dominant carbon-sulfur band. Temperature dependent electron paramagnetic resonance (T-EPR) showed shifts in the position of the differential absorption feature and anomalous signal broadening. Magnetometry results indicated the absence of superconductive transitions but a critical ferromagnetic temperature. Density functional theory (DFT) calculations showed that sulfur doping affected the system's metallicity.

Summary: The recent observations of unusual ferromagnetic and superconductive phenomena in sulfur-doped amorphous carbon and highly oriented pyrolytic graphite have attracted significant attention. This study presents a novel investigation on the relationship between magnetic ordering and sulfur-doping-induced structural modifications in pyrolytic graphite. The results demonstrate the nucleation of an unusual amorphous carbon film with sp(3)-rich characteristics as a result of chemical interactions between sulfur and HOPG. Magnetic characterization reveals a re-entrant spin-glass behavior, possibly originating from vacancy-defects created by sulfur migration. Additionally, long-time air-exposure of the samples was found to significantly enhance the diamagnetic component.

Summary: One of the most interesting structural features of multiwall carbon onions (MWCNOs) and nanotubes (MWCNTs) is their excellent chemical stability, which allows for in situ encapsulation of chosen magnetic materials and multifunctional applications. This letter presents an innovative chemical vapour synthesis (CVS) approach that incorporates small amounts of sulfur during pyrolysis to control the abundance of FCC gamma-Fe in the material's structure, up to a maximum value of approximately 86.5%. The variation in the relative percentage of the encapsulated Fe-based phases was estimated using X-ray diffraction (XRD) and Rietveld refinement analyses. Magnetic characterization was performed using superconducting quantum interference device (SQUID) magnetometry with zero field cooled (ZFC) and field cooled (FC) curves.

Summary: In this study, carbon nanotubes filled with faceted Fe3C nanowires were observed, exhibiting anomalous magnetic properties possibly attributed to strain effects of the crystal facets. Magnetic measurements revealed stepped magnetic hysteresis-loops and decreased coercivity at low temperature, indicating the presence of antiferromagnetic transitions within or at the boundary of the ferromagnetic facets. The existence of layered antiferromagnetic phases and potential spin-glass-like behavior induced by competing antiferromagnetic and ferromagnetic interactions were suggested. Low temperature XRD measurements also hinted at a slight variation in the Fe3C unit cell parameters, implying the absence of additional unit-cell volume induced ferromagnetic transitions at low temperature.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
