Summary: LaFe11.8Si1.2/16wt%La65Co35 samples were prepared by spark plasma sintering (SPS) and subsequent annealing. The La65Co35 binder increased the 1:13 phase content, and the alpha-Fe phase formed and disappeared during annealing. The sample annealed for 0.5 h showed a distinct core-shell structure, desirable table-like (-Delta S-M) -T curve, and higher RC value. The diffusion of Co was hindered by the growth of La5Si3 phase. Samples annealed for 24 h achieved larger (-Delta S-M)(max) and (sigma(bc))(max) values. The method combining SPS and diffusion annealing is promising for preparing La-Fe-Si based magnetocaloric composites with good properties.

Summary: Ceramic aerogels have attractive properties for applications in various fields due to their high porosity, low density, high specific surface area, low thermal conductivity, and thermal stability. However, the brittleness of conventional ceramic aerogels hinders their practical use. Resilient ceramic aerogels have overcome the brittleness issue but still exhibit brittleness under tensile stress and limited load-bearing ability. In this short review paper, strategies for modifying the mechanical properties of resilient ceramic aerogels are discussed, including the deformation and moving ability of nanowire building blocks and the deformation resistance provided by the aerogel architecture. Perspectives for further modification are also explored.

Summary: Commercial Nd-Fe-B sintered magnets were processed with Pr-Cu, Pr-Al, and Pr-Tb-Cu alloys through grain boundary diffusion, resulting in increased coercivity but reduced bending strength. Microstructure analysis showed that Cu enriched at grain boundaries, while Tb and Al atoms diffused into the main phase and caused lattice distortion, leading to decreased bending strength.

Summary: Transition metal nitrides, specifically zirconium nitride (ZrN) thin films, were fabricated using reactive direct-current (DC) magnetron sputtering and their morphology and electrochemical capacitive performance as electrode materials for supercapacitors were investigated. The films exhibited a continuous and homogeneous structure with a fine columnar morphology. The T3 film electrode showed the highest areal specific capacitance of 1.19 mF cm(-2) at a current density of 0.05 mA cm(-2) due to its higher porosity, better wettability, and lower charge transfer resistance.

Summary: Ferromagnetic La0.7Ba0.3MnO3 (LBMO), La0.7Sr0.3MnO3 (LSMO), and La0.7Pb0.3MnO3 (LPMO) nanoparticles were synthesized using the sol-gel auto-combustion method. Microstructural analysis revealed that the crystallite size and lattice strain of the nanoparticles changed with the increase of the mean radius of the A-site ion, influencing their structural and magnetic properties. Additionally, flexible nanocomposite films were prepared and used for energy harvesting based on the magnetoelectric effect from magnetic noise generated by cooling/exhaust fans and electric cable wires.

Summary: The use of granite industry waste as a mixing material in concrete can reduce natural aggregate consumption and solid waste disposal problems. This study found that incorporating recycled granite aggregate did not significantly affect the compressive strength of concrete, but did lower the tensile strength, especially in low-strength concrete. The presence of granite particles also decreased the workability of fresh concrete, as seen in the microstructure images showing weakened interfacial transition zones.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
