Summary: This study discusses the momentum of light in a medium, specifically focusing on the momentum transferred to an atom in a gas when it absorbs a photon. It presents a classical model for the absorbing atom's internal degrees of freedom and calculates the absorbed energy and momentum using the Lorentz force law. The results show that the average absorbed momentum is smaller than Minkowski's momentum, but experiments with Bose-Einstein condensates are consistent with Minkowski's momentum. The article argues that this discrepancy can be explained by the quantum nature of the condensate.

Summary: Designing multihierarchical electromagnetic wave-absorbing composites using metal-organic frameworks (MOFs) and in situ pyrolysis is an effective approach for enhancing absorption performance. A new magnetic carbon composite (gamma-Fe2O3 @N-rGO/MWCNT) with multihierarchical structure was prepared via an in situ anisotropic-oriented growth strategy. The composite exhibited exceptional absorption performance with a minimum reflection loss (RLmin) of -59.2 dB at 5.51 GHz, and the strategy used in this work has great potential for producing various multihierarchical nanocomposites with abundant absorption effects.

Summary: Comprehensive views on dielectric loss mechanisms provide important guidance for understanding the attenuation behavior of materials. Current researches focus more on materials synthesis rather than in-depth mechanism study. Therefore, further research on in-depth mechanisms, emphasis on new dielectric loss mechanisms, and new modulation strategies are needed to achieve simple and effective EM wave attenuation behavior modulation.

Summary: Magnetic alloy powders have shown advantages in electromagnetic wave absorption due to their balance of permittivity and permeability. However, their effective absorption bandwidth and impedance matching need to be improved, which can be addressed by high/medium-entropy alloys. In this report, Al(1.5)Co(3.5)Fe(3.5) and Al1.5Co3Fe3Cr MEAs were designed with excellent soft-magnetic properties and high resistivity. The special coherent microstructure of these alloys, with uniformly-distributed ultrafine magnetic body-centered-cubic nano-precipitates, contributes to their outstanding electromagnetic properties. The findings offer a useful design strategy for developing high-performance absorbers.

Summary: Cu-containing single-source precursors (SSPs) were synthesized to prepare SiCuCN-based ceramic nanocomposites. The transformation process, microstructural evolution, and dielectric properties of the ceramics were characterized. The results showed that Cu nanoparticles in the SiCN matrix can transform into copper silicide (Cu3Si) with improved thermal stability. The SiCuCN-based nanocomposites exhibited enhanced dielectric properties and excellent electromagnetic wave (EMW) absorbing performance, attributed to the unique network constructed by Cu and Cu3Si nanoparticles connected by carbon ribbons within the SiCN matrix.

Summary: Researchers synthesized a lithiophilic 3D copper foam host with uniformly distributed nano-flower-like ZnO particles (CuF/ZnO) and obtained a composite lithium metal anode (CuF/Li2O-LiZn@Li) containing Li2O, LiZn alloy, and pure Li by infusion of molten Li. The composite lithium metal anode, benefiting from the 3D structure of copper foam and the lithiophilicity of ZnO sites, can restrain volume alteration and regulate uniform lithium deposition. The symmetrical cells of the composite lithium metal anode exhibit a 1600-hour long cycle life with a low polarization voltage of 15 mV, and the Coulombic efficiency can maintain about 97.8% at 1.0 mA·cm(-2), 1.0 mAh·cm(-2).

Summary: SnO2 nanowires were synthesized locally by thermal evaporation method and its growth mechanism was confirmed. We proposed a simple strategy to achieve reduced graphene oxide (RGO)/SnO2 nanowires heterostructure. As expected, the gas-sensing response of the heterostructure was up to 63.3 when the gas concentration of trimethylamine (TEA) was 50 ppm, and it exhibited excellent dynamic response with high stability at 180 degrees C. A low detection limit of 50 ppb level was fully realized. Compared to SnO2 nanowires, the sensing performance of the RGO/SnO2 heterostructure-based sensor was greatly enhanced, attributed to the presence of RGO and heterostructure. The RGO/SnO2 composite engineering provided an easy way to make full use of the advantages originating from RGO and heterostructure.

Summary: This study evaluated the toxicity of functional carbon nanodots (FCNs) to zebrafish through acute toxicity tests at the embryonic and adult stages. The results showed that FCNs and nitrogen-doped FCNs (N-FCNs) caused developmental retardation, cardiovascular toxicity, renal damage, and hepatotoxicity in zebrafish. The main reason for these effects was the oxidative damage induced by high doses of materials and the biodistribution of FCNs and N-FCNs in the fish. However, FCNs and N-FCNs also promoted the antioxidant activity in zebrafish tissues to counteract the oxidative stress. Both FCNs and N-FCNs were proven to be biosecure to zebrafish, with FCNs showing higher biosecurity due to their physicochemical properties. The effects of FCNs and N-FCNs on hatching rates, mortality rates, and developmental malformations were dose-dependent and time-dependent. The toxicity ratings of FCNs and N-FCNs were defined as practically nontoxic for zebrafish embryos, and FCNs were relatively harmless. These results confirm the biosecurity of FCNs-based materials for future practical applications.

Summary: Garnet-type solid electrolytes are commonly used as fillers in polymer electrolytes to improve ionic conductivity and enhance mechanical strength. However, the presence of passive layers on the surface of garnet reduces its effectiveness. By modifying garnet fillers with an amphipathic coupling agent, the air stability of garnet is extended and the dispersion in the polymer matrix is improved. This leads to improved performance of the composite electrolyte.

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.
