Summary: NaF was composited into CCTO with excess Ti to prepare NaF/CCTO composite ceramics, and its physical and chemical properties were characterized. HRTEM revealed particle deposition on CCTO surface. FESEM showed the presence of nanocrystalline structures inside the grains in NaF/CCTO composite ceramics. Dielectric spectroscopy confirmed the significant improvement of CCTO's dielectric properties by NaF and excessive Ti. The dielectric constant of NaF-0.1 sample reached 2.7 x 106 and 5.1 x 105 at 20 Hz and 1 kHz, respectively.

Summary: High dielectric constant polymer dielectrics have garnered attention in flexible electronics. However, the increase in dielectric constant often leads to an increase in dielectric loss, posing a paradox. This study reports the use of core@double shell structured filler/PVDF composites to overcome this paradox. The composites, consisting of BaTiO3 as the core, conductive carbon as the inner shell, and insulating polydopamine as the outer shell, exhibit outstanding dielectric performance, with a dielectric constant of 45 and a dielectric loss of 0.053 at 10(3) Hz. This improvement can be attributed to the enhanced interfacial polarization induced by the inner carbon shell and the blockade of conductive paths caused by the outer PDA shell. These findings highlight the potential of rational design of core@double shell structured hybrid fillers for optimizing the overall dielectric performance of PVDF-based composites.

Summary: This study focuses on the preparation and microwave characterization of composites of M-type hexagonal ferrite with paraffin wax. The influence of Sr2+ ion content on material parameters, including grain morphology, dielectric, magnetic, conductivity, and reflection loss properties, was analyzed. The results indicate that higher Sr2+ ion content leads to lower dielectric and magnetic loss tangent, as well as increased AC conductivity with frequency.

Summary: This study demonstrates the synergistic zinc doping and defect engineering for MoS2 nanosheet arrays assembled on carbon cloth, which are directly used as a cathode for the hydrogen evolution reaction. By doping sufficient Zn atoms and introducing a defect-rich structure into the MoS2 nanosheets, active sites are increased synergistically, leading to highly efficient HER. Additionally, assembling these nanosheets on CC helps achieve lower charge-transfer resistance for the hydrogen evolution reaction.
