The transition metal dichalcogenide (TMDC) NbSe2 is a highly conductive and superconducting material with great potential for next-generation electronic optoelectronic devices. However, its bulk form suffers from reduced charge density conductivity due to interlayer van der Waals interactions. To address this, we exfoliated NbSe₂ into nanosheets using lithium-ion intercalation utilized them as diaphragms in acoustic transducers. Conventional electromagnetic electrostatic mechanisms have limitations sound pressure level (SPL) performance at high low frequencies, respectively. overcome developed hybrid force mechanism combining the strengths of both approaches. were successfully prepared analyzed, NbSe2-based transducer (N-HAT) demonstrated significantly improved SPL across wide frequency range. This study offers novel approach designing high-performance devices by harnessing unique properties NbSe2.

The performance of the cathodic hydrogen evolution reaction (HER) in alkaline water electrolysis, an attractive production technology, is highly dependent on efficient catalysts. Ruthenium (Ru), which more affordable than platinum (Pt) and has a metal–hydrogen bond strength comparable to that Pt, shows exceptional catalytic activity for HER. Consequently, recent years, research field through electrolysis increasingly focused Ru as key element. This review first discusses fundamentals HER, including principles, factors affecting its performance, regulation strategies improvement. progress ruthenium-based catalysts HER then summarized with selected examples. electronic structures various ruthenium nanoparticles, ruthenium-M (M = noble metals transition metals) heterogeneous catalysts, compounds are regulated by modulating components ligands atoms, aiming achieve low dissociation energies optimal binding (H) hydroxyl (−OH) groups, thereby enhancing performance. Finally, problems, challenges, future development directions proposed.
