Summary: This study analyzes the electromagnetic field of a bunch moving uniformly in a circular metal waveguide and crossing a boundary between a vacuum area and an anisotropic dispersive nonmagnetic medium. It is found that Cherenkov radiation in the filled area of the waveguide can have reversed direction in relation to the bunch motion, leading to the generation of intensive reversed Cherenkov-transition radiation (RCTR). The main properties of this radiation are described, highlighting essential differences from RCTR in the case of isotropic left-handed medium.

Summary: By using a reduction-reaction-induced self-assembly process, a new type of three-dimensional porous aerogel with partially unzipped multiwalled carbon nanotubes inserted into graphene nanosheets was prepared. The aerogels exhibited excellent electrical contact, prevented restacking of graphene nanosheets, and provided large channels for charge transfer, resulting in promising electrode materials for supercapacitor applications.

Summary: The proposed design of a novel three-dimensional porous continuous solid with negative Poisson's ratio exhibits cubic symmetry and moderate degree of anisotropy. The directional dependence of Poisson's ratio and Young's modulus shows multidirectional auxeticity. Numerical results are validated by experimental results from Digital Image Correlation data, with potential for large-scale industrial production.

Summary: A complex 3D multilayer deposition method was developed for the fabrication of single-walled carbon nanotubes (SWCNTs) using vacuum filtration and plasmonic carbonization, without the need for lithography and etching processes. The SWCNTs produced with this method can be stacked to form complex 3D structures with large surface areas, and show excellent mechanical stability even after elastic bending tests. Various characterization techniques were used to confirm the properties of the 3D multilayer SWCNT patterns.

Summary: To address the safety and performance issues in lithium metal-based anode, a high-performance Li host anode composite is developed by coating lithiophilic vanadium oxide onto three-dimensionally structured N-doped CNT rooted on carbon nanotube film. This composite anode exhibits a dendrite-free morphology and excellent cycling performance in lithium-sulfur batteries, thanks to the buffering effect of the porous structure and the sufficient lithium nucleation sites provided by the N-doped CNTs. The cycling stability of the battery is also demonstrated with a capacity decay rate per cycle less than 0.05% after 500 cycles.

Summary: An environmentally friendly liquid exfoliation and subsequent freeze-drying approach for constructing a three-dimensional carbon-based network using few-layer graphene (FLG) and carbon nanotubes (CNTs) was proposed for electromagnetic interference (EMI) shielding applications. Characterizations and EMI shielding tests indicated that the composite exhibited excellent shielding performance after freeze-drying, and the introduction of CNTs improved the shielding effect of FLG significantly.
