Control of structure and corrosion performance in PEO coatings on AZ91/Ti composites: influence of electrolyte composition

The reinforcement phases in magnesium matrix composites (MMCs) may negatively impact the discharge behavior and corrosion resistance of PEO coatings, posing challenges to their application. This study investigates the PEO of AZ91/Ti composites in mixed electrolytes with varying compositions. It focuses on optimizing the coating phase composition to regulate the electrical structure and discharge behavior. These improvements ultimately improve the coating structure and performance. The results demonstrate that PEO treatment in mixed electrolytes containing silicates, phosphates, and aluminates produces a dense, self-sealing coating structure, significantly reducing the self-corrosion current density by an order of magnitude. Specifically, the presence of aluminates promotes the formation of an insulating layer on Ti reinforcement phase regions and facilitates the generation of Al 2 TiO 5 . Meanwhile, phosphates enhance MgO content in the Ti reinforcement phase regions, promoting the formation of MgTiO 3 . The synergistic effect of low-dielectric-constant phases, Al 2 TiO 5 and MgTiO 3 , reduces discharge intensity in Ti reinforcement phase areas, resulting in a dense and self-sealing pore coating structure with improved corrosion resistance.

Passivating undercoordinated ions is an effective way to reduce the defect densities at the surface and grain boundaries(GBs)of perovskite materials for enhanced photovoltaic performance and stability of perovskite solar cells(PSCs).Here,(BBF)complex is chosen as a multifunctional additive,which contains both C7H9N and BF3 groups working as Lewis base and Lewis acid,respectively,can bond with Pb^(2+)/I^(−) and FA+on the surface and in the GBs in the perovskite film,affording passivation of both cation and anion *** synergistic effect of the C7H9N and BF3 complex slows the crystallization during the perovskite film deposition to improve the crystalline quality,which reduces the trap density and the recombination in the perovskite film to suppress nonradiative recombination loss and minimizes moisture permeation to improve the stability of the perovskite ***,such an additive improves the energy-level alignment between the valence band of the perovskite and the highest occupied molecular orbital of the hole-transporting material,***,our work achieves power conversion efficiency of 23.24%,accompanied by enhanced stability under ambient conditions and light illumination and opens a new avenue for improving the performance of PSCs through the use of a multifunctional complex.

The anisotropic two-dimensional （2D） layered material rhenium disulfide （ReSe2） has attracted considerable attention because of its unusual properties and promising applications in electronic and optoelectronic devices. However, because of its low lattice symmetry and interlayer decoupling, anisotropic growth and out-of-plane growth occur easily, yielding thick flakes, dendritic structure, or flower-like structure. In this stud34 we demonstrated a bottom-up method for the controlled and scalable synthesis of ReSe2 by van der Waals epitaxy. To achieve controllable growth, a micro-reactor with a confined reaction space was constructed by stacking two mica substrates in the chemical vapor deposition system. Within the confined reaction space, the nucleation density and growth rate of ReSe2 were significantly reduced, favoring the large-area synthesis of ReSe2 with a uniform monolayer thickness. The morphological evolution of ReSe2 with growth temperature indicated that the anisotropic growth was suppressed at a low growth temperature （〈600 ℃）. Field-effect transistors employing the grown ReSe2 exhibited p-type conduction with a current ON/OFF ratio up to 10s and a hole carrier mobility of 0.98 cm^2/（V·s）. Furthermore, the ReSe2 device exhibited an outstanding photoresponse to near-infrared light, with responsivity up to 8.4 and 5.1 A/W for 850- and 940-nm light, respectively. This work not only promotes the large-scale application of ReSe2 in high-performance electronic devices but also clarifies the growth mechanism of low-lattice symmetry 2D materials.
