Here, we demonstrated that migration away from a thermal dynamic invariant point (eutectic) leads to partitioning in metal alloys, resulting in differentiable phase change events. Evolution in heat capacity, enthalpy, and entropy of non-eutectic mixtures was analyzed. Asymmetry in enthalpy dissipation peak during phase transition further confirms this partitioning-driven divergence in entropy change. We infer that, when a liquid metal is not in equilibrium, <em>in situ</em> partitioning, speciation, and segregation can occur, generating new interfaces that abet the undercooling and retention of the liquidous state. This work highlights the role of opposing interfacial stresses and entropy changes in generation of microsystems in non-equilibrium mixtures.","PeriodicalId":388,"journal":{"name":"Matter","volume":"127 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To elucidate how structural changes influence optoelectronic properties, we interrogate a series of 2D lead bromide and iodide perovskites with different-length alkylammonium cations. We find that the octahedra become either more or less distorted at the phase transition temperature, depending on the identity of the cation and halide, and that octahedral motion occurs either continuously with temperature or abruptly across a phase transition.

Using liquid-phase transmission electron microscopy, we visualize the spontaneous assembly of semicrystalline amphiphilic BCPs. We observe structural transformations from unimers to spherical, cylindrical, toroidal micelles, and vesicles by varying constituent block ratios. Image segmentation overcomes low contrast of aqueous assemblies, enabling motion tracking. Nanostructures exhibit structural evolution driven by long-range hydrophobic interactions from formed elemental micelles undergoing anomalous diffusion.
