Summary: In this study, the thermal transport properties of BC3 nanotube (BC3NT), a newly synthesized representative of 1D carbon boron compounds, were investigated using non-equilibrium molecular dynamic simulations. The lower thermal conductivity of BC3NT compared to carbon nanotube was found to be caused by the strong phonon coupling induced by atomic mass discrepancy and polarized covalent bond. Furthermore, it was discovered that strain can effectively modulate the thermal conductivity of 1D systems, with small tensile strain enhancing the thermal conductivity and large tensile and compressive strain impeding phonon transport.

Summary: Phonons are the main carriers of heat in semiconductor devices. In small devices, the heat is driven by local points of heat input and removal rather than a local temperature gradient, which complicates theoretical modeling. Studying the propagation of vibrational energy from an initial localized pulse provides insight into the nonlocal heat transport of phonons.

Summary: Aligned carbon nanotube bundles exhibit negative lateral thermal expansion under lateral loading and heating conditions. The coefficient of thermal expansion is practically constant up to 1500 K and does not depend on biaxial lateral compression. This anomalous behavior is explained by the elliptization of the CNT cross section and bending of the CNT walls by thermal fluctuations.

Summary: This review highlights the significance of one-dimensional chains as a fundamental model for condensed matter and their contributions to developments in nonlinear physics and complex systems. The pioneering work by Fermi, Pasta, Ulam, and Tsingou in the 1950s laid the foundation for extensive mathematical and physical research in this field over the past 70 years. Recently, the Wave Turbulence approach has provided new insights into the mechanisms of thermalization in such systems. The review critically summarizes the obtained results and identifies open problems and challenges for future investigations.

Summary: We designed a one-dimensional granular chain as a granular container, aiming to reduce the force transmitted to a fixed boundary barrier. This chain consists of ordered heavy and light beads, exhibiting strongly nonlinear acoustics and zero tensile strength leading to bead separations and subsequent collisions. By exploring the relationship between transmitted force and mass ratio of beads, as well as the number of beads in each subchain, we derived an optimal design to minimize transmitted force. The experimental validation and estimation of damping and linear stiffness further confirmed our computational predictions. Moreover, both simulations and experiments revealed transient, propagating localized oscillations due to the strong nonlinearity of the granular chain, indicating the potential for enhanced performance compared to linear shock absorbers.

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: One-dimensional carbon chains, highly reactive allotropes that have only been synthesized within carbon nanotubes, can be encapsulated in alpha-MnO2 with open structural channels, according to DFT simulations. The stabilization of cumulene chains is due to structural commensurability with alpha-MnO2 channels, while the triple bonds in polyyne chains experience excessive steric repulsion to the oxide ions bordering the channel.

Summary: We investigate the crossover from ergodic to nonergodic behavior in an interacting spin chain with sparse impurity density. By studying the relaxation and delocalization of these impurities, we find that they always exchange energy with the rest of the chain, leading to weakly dependent relaxation rates and exponential decay with field strength. This relaxation is connected to operator spreading and hinders the construction of local integrals of motion. In the high field limit, the impurities appear localized, but eventual delocalization occurs due to a flowing localization length.

Summary: This study demonstrates that amine-containing aromatic and cyclohexane molecules can effectively disperse single-walled carbon nanotubes (SWCNTs) in solvents, leading to stable dispersion at the single-tube level. The interaction between the amine group of the molecules and the pi bond of SWCNTs plays a crucial role in achieving excellent dispersibility and stability. Additionally, the enhanced thermal and electrical properties of SWCNT/epoxy nanocomposites through the introduction of these molecules provide a promising new approach for industrial applications.

Summary: The electronic structure of phosphorene atomic chains embedded in different dielectric environments is theoretically studied using a configuration interaction method. It is found that, in addition to the expected scaling law of L², the quasiparticle shift and exciton binding energies follow certain scaling laws, with the former converging to a value independent of the dielectric environment as the length of the atomic chains increases.

Summary: Fine control over material synthesis on the nanoscale has allowed for the selective creation of one-dimensional TaTe3 chains or two-dimensional TaTe2 nanoribbons using carbon nanotube reaction vessels. This control extends to the number of chains or the thickness and width of nanoribbons. Transmission electron microscopy and scanning transmission electron microscopy provide detailed atomic structure of the encapsulated materials, revealing complex superstructures such as multichain spiraling and multilayer moire patterns.

Summary: A series of fullerene-based 1D chains with both ferroelectricity and ferromagnetism are designed using first-principles calculations. The introduction of transition metal atoms enhances the spontaneous polarization and leads to various magnetic properties. These findings not only broaden the range of 1D multiferroic materials, but also provide promising candidates for novel electronic and spintronic applications.

Summary: This work focuses on bifurcation and chaotic behavior in one-dimensional chains of small particles. Two possibilities are considered: one with particles modeled by a fourth-order potential that has been previously studied, and the other with particles modeled by an eighth-order potential that is new. The study investigates the behavior of orbits, bifurcation profile, and Lyapunov exponent for both systems.

Summary: The analysis showed that MWCNTs enhance fracture toughness by deflecting crack paths, but the higher concentration of MWCNTs leads to a reduction in composite porosity. The study also found that MWCNT addition below 0.5 wt.% does not significantly increase fracture toughness due to the competing factors.
