Hydrogen production through electrochemical seawater splitting is challenged by the energy-intensive oxygen evolution reaction and the competing chlorine evolution reaction. To overcome these obstacles, ligand-free platinum bismuth (PtBi) alloy nanoparticles (≈2 nm) are synthesized via femtosecond laser liquid ablation under nonequilibrium conditions, yielding metastable structures with tunable elemental compositions populated with defects. The PtBi/C catalyst excels in alkaline methanol oxidation reaction (MOR), delivering a mass activity of 17.

The direct low-temperature synthesis of crystalline silicon nanowires (c-SiNWs) on flexible polymer substrates remains a critical yet unrealized milestone for scalable flexible thin-film transistors (TFTs), hindered by the interfacial mechanical mismatch between rigid silicon and deformable polymers and the ultralow thermal budgets imposed by the flexible substrates. Though nanoscale SiNW channels can be patterned/grown and transferred onto polymer substrates, high-precision postgrowth transferring and alignment of these tiny SiNW channels remain technically difficult or too cost-intensive for the implementation of large-area electronics. Here, we demonstrate a direct growth of orderly c-SiNW channels upon a flexible polyimide (PI) film for the first time, through an in-plane solid-liquid-solid (IPSLS) mechanism at 200 °C, achieving uniform diameters of 44 ± 5 nm.

Ni-rich single-crystalline cathodes are pivotal for advancing lithium-ion battery technology due to their high energy density and mechanical stability. However, Ni-rich single-crystalline particles face intrinsic structural heterogeneity due to excessively high sintering temperature required to shape micron-sized morphologies─typically over 150 °C above the polycrystalline optimum, leading to rapid electrochemical decay and unsatisfied rate performance that hinder their practical application. Here, we propose a lithium-deficient presintering strategy to synthesize cation-ordered single-crystalline LiNiCoMnO (S-NCM83), effectively minimizing lattice chemical heterogeneity and defect formation.
