The goal is to provide direct experimental evidence for the entropy-lowering molecular cluster formation hypothesized as necessary for LCST behavior. Differential wide-angle X-ray scattering and pair distribution analysis and small-angle X-ray scattering measurements were combined with molecular modeling and liquid-liquid equilibrium measurements, revealing direct experimental evidence for the hypothesis. However, the response of the amine phase to accommodating water is even more subtle than the simple hypothesis suggests, with the formation of robust nanoscale reverse micelles. The techniques developed in this paper can be expected to yield insights in the use of temperature-switchable liquids in solvent extraction and other separations, and the stabilization of organelles in living cells that do not have physical membranes but do require compositional gradients to operate.","PeriodicalId":388,"journal":{"name":"Matter","volume":"43 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439777","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}

Galvanostatic and potentiostatic post-treatments can rejuvenate degraded electrochromic layers. However, these procedures require high oxidation potentials, which are neither safe for the electrode-electrolyte system nor compatible with the operation of a full device. In the present paper, we report that degraded electrochromic oxides can be rejuvenated by a photo-electrochemical synergistically induced ion detrapping procedure. The UV light-induced photocurrent assists ion detrapping and limits the applied potential to the safe range used for electrochromic switching. This approach has been demonstrated to be effective for several cathodic electrochromic oxides and can be directly implemented in a full device. Our findings provide new vistas for efforts to expand the lifespan of electrochromic devices and other ion intercalation-based devices.","PeriodicalId":388,"journal":{"name":"Matter","volume":"10 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439779","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}

Conventional melt-based single-crystal growth methods are dominated by strict and complicated processes, usually leading to small and expensive single crystals. Here, we report a solid-based approach, namely “texture-engineered grain growth,” for preparing bulk single crystals in a controllable and cost-efficient manner. Using copper as an example, we show that deformation texturing can effectively induce abnormal grain growth of cold-drawn copper bars during recrystallization, in which {111} grains grow preferably by coalescing neighboring small grains. Moreover, the applied temperature gradient enables the as-formed abnormally large grain to act as a seeding crystal to expand directionally throughout the entire textured copper bar, readily converting the textured polycrystals into a bulk single crystal. The technique is also applicable to the growth of bulk single-crystal nickel. The texture-induced monocrystallization strategy would advance large-scale manufacturing and applications of bulk single crystals.","PeriodicalId":388,"journal":{"name":"Matter","volume":"230 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142436290","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}

Using multi-modal diagnostics, we prove that NPLs ripen and grow, playing a decisive role in the time evolution of QW size, population distribution, and orientation. We demonstrate antisolvent drip interrupts NPL ripening and thereby controls QW orientation, population, and energy cascades within LHP films. Using this approach, we achieve low-threshold amplified emission (AE) with remarkable reproducibility. We further introduce synthesized NPLs in the antisolvent step of 3D perovskites to control facet orientation and achieve enhanced efficiency and stability in wide-bandgap solar-cell devices compared to untextured controls.","PeriodicalId":388,"journal":{"name":"Matter","volume":"26 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405548","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}
