Summary: This work extends the concept of disorder hyperuniformity to quasi-one-dimensional materials like carbon nanotubes, and quantifies density fluctuations in amorphous carbon nanotubes with randomly distributed Stone-Wales defects. The study finds that all of these amorphous nanotubes exhibit hyperuniformity, regardless of their properties, and that they are energetically more stable than metallic nanotubes as more defects are introduced.

Summary: In a quasi-one-dimensional system with low defect concentration, the resistivity exhibits peaks as a function of Fermi energy, with deep narrow gaps appearing at the center of each peak due to non-Born scattering effects. Scattering at rare twin pairs of close defects dominates the resistivity at the bottom of these gaps, while scattering at solitary defects is suppressed. This predicted effect is characteristic of multi-channel systems and cannot be observed in strictly one-dimensional systems.

Summary: The severe imbalance between supply and demand in organ resection or severe tissue damage poses life-threatening risks. Carbon nanotubes (CNTs) have emerged as promising platforms due to their unique properties. CNTs are commonly used as additives in tissue engineering scaffolds to modify structure, porosity, mechanical strength, and more. This review summarizes the applications and design strategies of CNTs in various tissue engineering fields and discusses their potential biosafety risks and solutions. Future developments of CNTs in tissue engineering are also speculated.

Summary: Strong intertube excitonic coupling is demonstrated in 1D van der Waals heterostructures through the interaction of dipole-dipole Coulomb interactions and light-matter interactions. This leads to the creation of intertube biexcitons on short timescales and intertube excitons on longer timescales, which opens up new possibilities for multi-functional applications of these new nanoscale coaxial cables.

Summary: A 1D semimetal-2D semiconductor contact using single-walled carbon nanotube electrodes is able to achieve contact lengths in the sub-2 nm region, with smaller van der Waals gaps and tunable Schottky barrier heights via gate potential for Ohmic contact. The study presents a basis for further miniaturization of nanoelectronics.

Summary: In a recent article published in Science Bulletin, Dong et al. reported a quasi-one-dimensional TlCu3Te2 bulk material with a high application-level room temperature ZT value of 1.3. This is attributed to the presence of a pancake-like Fermi pocket with a quasi-one-dimensional dispersion at the narrow band-gap edge, as well as a large, anharmonic quasi-one-dimensional lattice structure formed by heavy Tl+ ions and weakly bonded Cu+ ions.

Summary: The synthesis of one-dimensional van der Waals heterostructures enables new possibilities in electronics and optoelectronics, with different electrical characteristics induced by natural doping in semiconducting single-walled carbon nanotubes and molybdenum disulfide. Assembling semiconducting single-walled carbon nanotubes, insulating boron nitride nanotubes, and semiconducting molybdenum disulfide nanotubes creates a radial semiconductor-insulator-semiconductor heterojunction. Application of opposite potential polarity on these nanotubes leads to a rectifying effect.

Summary: Interference effects in finite sections of one-dimensional moire crystals were investigated using a Landauer-Buttiker formalism within the tight-binding approximation. The study explains interlayer transport in double-wall carbon nanotubes and proposes a predictive model. Results show visible wave function interference at the mesoscale, which can be exploited for designing quantum electronic devices.

Summary: The confinement effect induced conformational evolution of one-dimensional (1D) phosphorus atomic chains encapsulated inside carbon nanotubes (CNTs) has been studied. The study shows that as the inner diameter of CNTs increases, the phosphorus chains change from monoatomic linear chain to (P8P2)n chains. These encapsulated (P8P2)n chains exhibit excellent structural stability and can serve as potential building blocks for nano-electronic and molecular electronic devices.

Summary: By applying pressure, quasi-one-dimensional metallic properties were achieved in the three-dimensional metal halide CsSnI3. The pressure-induced hybridization between Sn-Sn and enhanced coupling between Sn-I within the chain resulted in band gap closure and the formation of conductive SnI6 distorted octahedral chains. Meanwhile, the minimal interactions between interchain I...I led to a highly anisotropic electronic structure.

Summary: In this study, a one-dimensional (1D) van der Waals material Nb2Se9 was grown as nanowire arrays using a liquid precursor-assisted chemical vapor deposition (CVD) process. Compared to other synthesis methods, the aligned Nb2Se9 nanowires exhibit higher photoresponse and stability. This controllable CVD growth offers a possibility of using aligned Nb2Se9 nanowires as building blocks for large integrated circuits based on 1D materials.

Summary: In this study, ultracold superfluid Bose-Fermi mixtures in three dimensions with stronger confinement along one or two directions are investigated using a non-perturbative beyond-mean-field model. Two possibilities for the fermions are considered - a spin-polarized degenerate state and a superfluid state. Simplified lower-dimensional models are derived for the weak-coupling to unitarity crossover in quasi-one-dimensional and quasi-two-dimensional settings. The validity of these reduced models is demonstrated through a comparison with the numerical solutions from the full three-dimensional model.
