Summary: One dimensional carbon nano materials are widely studied for their potential in electromagnetic wave (EMW) absorption. However, their agglomeration and mismatched impedance pose challenges. To address this, we developed a hierarchical architecture by growing amorphous carbon nanotubes (CNTs) on carbon nano fibers (CNF) converted from bacterial cellulose (BC), resembling the structure of pine leaves. This not only solved the agglomeration issue but also enhanced interface polarization capability. The resulting CNTs/CNF composites showed excellent EMW absorption properties with a reflection loss of -68.2 dB and a maximum effective absorption bandwidth of 5.5 GHz.

Summary: Designing lightweight, damage-tolerant, and sustainable materials is crucial for technological advancements. Lattice materials have shown potential for achieving multifunctionality, and their performance can be enhanced through structural hierarchy. However, there is still a gap in achieving the perfection seen in natural materials. In this study, 3D hierarchical lattice structures were analyzed to understand the role of hierarchical strategies. The results showed that introducing structural heterogeneity can improve mechanical properties, while structural hierarchy has minimal impact on deformation behavior but extends functionality. This research opens new possibilities for various applications. (c) 2022 Elsevier Ltd. All rights reserved.

Summary: Flash-sintered ceramics show better mechanical deformability than conventional sintered ceramics, and the high-density defects formed under electrical field plays a key role. However, direct experimental evidence for defect formation and evolution is lacking. In this study, in situ TEM experiments were conducted to observe the defect dynamics in flash-sintered and conventionally sintered TiO2. The results showed that both types of samples exhibited the coalescence of point defects and the formation of stacking faults under electrical field. Surprisingly, the fault growth rate in flash-sintered samples was 10 times higher than that in conventionally sintered samples, and the formation of the Magneli phase was only observed in flash-sintered samples.

Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
