Summary: The scattering theory for two crossing metallic single-walled carbon nanotubes of finite length exposed to an electromagnetic field has been developed, incorporating the influence of the contact conductance, position, and angle between tube axes on the tube polarizability. The physical mechanisms responsible for the electromagnetic interaction between crossing tubes with zero and nonzero intertube contact conductance have been discussed, along with the demonstrated influence of coupling between the tubes on their localized plasmon resonance.

Summary: Thermoelectric materials offer a promising solution for recovering wasted energy, but their efficiency is low and the best materials are brittle, toxic, and expensive. This study demonstrates that flexible films of double-walled carbon nanotubes can achieve low thermal conductivity and high electrical conductivity, leading to the development of flexible, cheaper, and more efficient thermoelectric generators.

Summary: This paper applies the DCM method to predict the buckling of inner tubes of DWNTs, showing that the lengths and radii of outer tubes influence the buckling patterns of inner tubes. The inner tubes of DWNTs with an interlayer spacing of 0.2034 nm have the strongest buckling resistance, and the local critical axial compression ratio of inner tubes increases with the lengths of inner and outer tubes when the interlayer spacing of DWNTs is less than 0.34 nm.

Summary: A double-shelled carbon-based nanobox integrated with size-asymmetric Co single atoms and metallic Co nanoparticles was successfully fabricated using a facile chemical etching/in-situ capture synthesis strategy. The catalyst exhibited remarkable bifunctional electrocatalytic performances in alkaline electrolytes, with a decent half-wave potential for oxygen reduction reaction and a small overpotential for oxygen evolution reaction. The strong interaction between the Co single atoms and Co nanoparticles optimized the adsorption and desorption energy barriers of reaction intermediates, leading to synergistic enhancement of electrocatalytic activity. This finding provides a feasible and effective strategy for highly active and durable bifunctional catalysts in practical rechargeable ZABs applications.

Summary: Halloysite nanotubes (HNTs) modified with nanomanganese cobaltate (MnCo2O4) can drive peroxymonosulfate (PMS) to generate reactive oxygen species (ROS) for the high degradation efficiency and mineralization rates of antibiotic pollutants such as ornidazole (ONZ). The MCO@HNTs + PMS system exhibits excellent catalytic activity, stability, and anti-interference effect in the wide pH range. Singlet oxygen (1O2) is identified as the main ROS for ONZ degradation. The study provides a simple, environmentally friendly, and cost-effective PMS activation catalyst for the treatment of antibiotic wastewater.

Summary: A Fe-Ni alloy catalyst was synthesized by the rational design of electronic-structure modulation through nano-alloying, with the alloy particles embedded in an N-doped carbon nanobox. The catalyst showed superior performance compared to commercial noble-metal benchmarks, with a decent half-wave potential of 0.891 V for ORR and a small overpotential of 325 mV at 10 mA/cm2 for OER in 0.1 M KOH solution. Additionally, a highly-efficient regenerative Zn-air battery was successfully constructed, exhibiting a small potential gap of 0.664 V, high specific capacity of 763 mAh/g, large peak power density of 270 mW/cm2, and robust stability. Ultraviolet photoelectron spectroscopy and theoretical simulation confirmed that the alloying of Ni into Fe could manipulate the electronic structure and lower the reaction barriers of intermediates during the electrocatalytic ORR/OER processes.

Summary: Plasmonic solid-state nanopores with tunable hole diameters can be prepared using a photocatalytic effect caused by the enhanced electromagnetic field inside a metallic ring on top of a dielectric nanotube. This approach enables the reduction of the initial inner diameter of the nanopore and allows for optimized detection of single entities with different sizes, such as double stranded DNA and gold nanoparticles. Numerical simulations show that a field intensity enhancement of up to 10^4 can be achieved inside the nanopores, which can be used for enhanced optical measurements and local heating.
