Summary: All-solid-state structural supercapacitors (ASSCs) are multifunctional energy storage devices with great potential in the field of building applications. However, the low energy density has been a major limitation. In this study, a novel 3D nanosheet material is designed to enhance the areal-energy-density of ASSCs. By incorporating S (Na2S center dot 9 H2O) into rGO/N1C1M nanosheets, a significantly higher areal capacitance is achieved, demonstrating superior performance compared to previous rGO/NCM electrodes. A prototype device of asymmetric ASSCs exhibits excellent performance, with high areal capacitance and areal-energy-density. The demonstration of using the designed electrode opens up new opportunities for high-performance ASSCs in building energy storage.

Summary: In this study, an innovative approach for fabricating efficient electromagnetic shielding material by tuning the microstructure of the filler in a flexible PDMS polymer matrix is presented. The magnetic property is found to be changed significantly by transforming the microstructure from solid to hollow. The electromagnetic shielding effectiveness is further enhanced by the addition of reduced graphene oxide. The dielectric and magnetic properties of the composite can be altered by varying the mass ratio of the precursors.

Summary: This study demonstrates the use of S and Se co-doping to stabilize p-type AgSbTe2 materials, which exhibit an outstanding maximum figure of merit (zT(max)) of 2.3 at 673 K and an average figure of merit (zT(ave)) of 1.59 over the wide temperature range of 300-673 K. The exceptional performance is attributed to enhanced carrier density, improved Seebeck coefficient, and higher stability beyond 673 K. These results provide an effective strategy for engineering high-performance TE materials in the mid-temperature range.

Summary: It is found that 001 textured ceramics have higher d(33) values compared to random and 111 textured ceramics, while 111 textured ceramics exhibit higher Q(m) values due to less polarization rotation. MnO2 doping can further improve the Q(m) values for both 001 and 111 textured ceramics. These results highlight the potential of textured piezoelectric ceramics for high-power applications.

Summary: This study demonstrates a high-performance Gd5Si2.4Ge1.6 thermomagnetic alloy that meets the requirements of magnetic phase transition, magnetization change, and thermal conductivity. By introducing Ge doping in Gd5Si4, the magnetic phase transition temperature was successfully shifted to 306 K, and a sharper and more symmetric magnetization behavior with a saturation magnetization of M (max) = 70 emu/g at a 2 T magnetic field was achieved in the ferromagnetic state. The addition of SeS2 as a low-temperature sintering aid improved the material's density and thermal conductivity by approximately 45% and 275%, respectively. The (Gd5Si2.4Ge1.6)(0.9)(SeS2)(0.1) alloy is confirmed as a suitable composite material for low-grade waste heat recovery in thermomagnetic applications.
