Summary: The ocean is a vast potential source of renewable energy, but low-frequency and high-amplitude stimulation has made harnessing its power challenging. Hybrid nanogenerators (HNGs) offer a promising solution by efficiently converting ocean energy into usable power. With their high sensitivity and flexible design, HNGs are ideal for low-frequency environments and remote ocean regions. By combining triboelectric nanogenerators (TENGs), piezoelectric nanogenerators (PENGs), and electromagnetic nanogenerators (EMGs), a unique hybrid system is created that maximizes energy harvesting.

Summary: The development of triboelectric nanogenerators (TENGs) has rapidly advanced in the past decade. In this study, ethylene vinyl acetate (EVA) polymer and lead zirconium titanate (PZT) were used as host materials. EVA-PZT elastomer composites were fabricated with different weight percentages of PZT in EVA by solvent casting. X-ray diffraction investigation confirmed the presence of PZT material and formation of composites. TENGs have the potential to revolutionize energy harvesting and provide sustainable energy for various applications. The electrical output performance of a single-electrode-mode-based TENG was examined, and the EVA-PZT 7.5 wt%/Al-based TENG device showed the maximum output of 60 V and 165 nA. Furthermore, TENG was used to power devices and gather biomechanical energy.

Summary: This study investigates the microstructure and magnetic properties of a sintered magnet with Ce substitutions. The addition of Ce resulted in lattice contraction, with further increase in Ce content leading to a suppression in lattice contraction. The magnets with higher Ce content exhibited the REFe2 phase at the expense of a reduced mass fraction of the REOx phase. The valence state of Ce changed from a mixed state to a trivalent state, and a bi-layer interfacial structure was formed between the RE2Fe14B and the REFe2 phases.

Summary: A comprehensive study on the structural, electronic, and magnetic properties of Co-substituted Fe2CrSi Heusler alloys was conducted. The effect of rapid solidification on the formation of pure phase Fe2CrSi alloy was also investigated. The results revealed that Fe2CrSi alloys with Co substitution in the range of 0.2 <= x <= 0.5 exhibited a single L21 phase structure, while those with x = 0 and 0.1 had impurity phases coexisting with the L21 phase. The high speed melt-spinning process resulted in higher purity in the alloy samples. First principles calculations showed that the single phase ribbon sample exhibited disorder, indicating a change in site preference due to solidification rate. The magnetic moments of the alloys were consistent with the Slater-Pauling rule. Fe2Cr0.75Co0.25Si alloy was suggested as a promising candidate for spintronic device applications due to its half-metallic nature.
