ZnIn₂S₄ nanosheets with S vacancy (V_s-ZIS) were successfully synthesized on bulk Sr₆Co₅O₁₅ (SCO) via a solvothermal method in this study. The formation of the V_s-ZISCO S-scheme heterojunction (SSH) was substantiated by DFT calculations, KPFM, EPR and in situ XPS. The incorporation of sulfur defects effectively mitigates the inefficient electron movement within the ZISCO heterojunction, thereby reducing energy loss of internal electron and concentrating electron transfer primarily at the contact interface. Furthermore, the design of sulfur vacancies facilitates an appropriate Fermi level (E_f) potential difference between V_s-ZIS and SCO. This significantly enhances carrier injection at the heterojunction interface, thereby substantially strengthening the internal electric field (IEF). In comparison with pristine ZIS, the electron transfer quantity at the interface between V_s-ZIS and SCO was elevated by 41.38 %. The design of sulfur defect and the construction of SSH effectively modulate the d-band center, shifting it downward. This adjustment facilitates the desorption of intermediate state H∗. Specifically, the V_s-ZISCO's Gibbs free energy of hydrogen adsorption (ΔG_H∗) approaches zero, thereby achieving an optimal balance between hydrogen atom desorption and adsorption.</div></div>","PeriodicalId":18253,"journal":{"name":"Materials Today Physics","volume":"57 ","pages":"Article 101812"},"PeriodicalIF":9.7,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In metal super-hydrides, when H atoms are removed, the remaining metal sublattices exhibit characteristics of interstitial quasi-atomic (ISQ) orbitals occupied by electrons. In this paper, 124 kinds of systems (including AHCu₃ and MgHE₃) are constructed by replacing Mg atoms with A atoms or replacing Cu atoms with E atoms in the MgHCu₃ system. By systematically studying the intrinsic relationship between the superconductivity and stability of these systems and their electronic structures, three strategies are proposed for screening stable structures or optimizing the superconductivity of the system efficiently. (1) Stability rapid screening strategy: We establish an effective stability criterion based on the matching between the electron localization function (ELF) characteristics of the replacement system and the parent system, and its prediction accuracy reaches up to 76 %. This result provides a reliable electronic structure basis for the prediction of superconductor stability, which can improve the screening efficiency of stable structures. (2) Hydrogen atom embedding strategy: “Chemical templates that assemble the metal super-hydrides”, based on this idea, we propose a reverse design strategy for hydrogen-rich superconductors by using three different hydrogen embedding methods based on the ELF characteristics of the metal lattice, nine new hydride superconductors are successfully designed, including MgH₄Cu₃, PdH₄Cu₃, NaH₄Cu₃, AgH₄Cu₃, LiH₄Cu₃, MgH₄Na₃, Cu₄H₄, MgH₇Ba₃, and Mg₄H₉. Among them, Mg₄H₉ has a <em>T</em>_c of 84.4 K at 20 GPa, and MgH₇Ba₃ has a <em>T</em>_c of 54.8 K at 50 GPa. (3) Strain control strategy: By applying 5 % tensile strain to the MgHNa₃ system, its <em>T</em>_c was successfully increased from 16.4 K to 28.4 K. This strategy applies to superconductors whose superconductivity is negatively correlated with pressure and are stable at ambient pressure.

However, kinetic mechanisms and property evolution associated with such treatments remain underexplored. In this study, effects of aging at 523 K from 0 to 1200 min on martensitic transformation (MT), magnetocaloric effect (MCE), and atomic order of bulk Ni₄₇Co₅Mn₄₀Sn₈ alloy were systematically investigated. As aging time increased, MT temperature initially decreased rapidly, followed by a slower decline, with a total drop of ∼7 K. This behavior reflects a diffusion-limited ordering process, where atomic rearrangement slows as defect mobility and driving force decline. Meanwhile, austenite Curie temperature increased by 4.2 K, resulting in an ∼11.2 K expansion of ferromagnetic austenite region. Enhanced field-induced transformation behavior was observed.
