Traditional lab automation infrastructure faces challenges adapting to new experiments. To address this, we introduce ORGANA, an assistive robotic system that automates diverse chemistry experiments using decision-making and perception tools. It makes decisions with chemists in the loop to control robots and lab devices. ORGANA interacts with chemists using large language models (LLMs) to derive experiment goals, handle disambiguation, and provide experiment logs. ORGANA plans and executes complex tasks with visual feedback while supporting scheduling and parallel task execution. We demonstrate ORGANA’s capabilities in solubility, pH measurement, recrystallization, and electrochemistry experiments. In electrochemistry, it executes a 19-step plan in parallel to characterize quinone derivatives for flow batteries. Our user study shows ORGANA reduces frustration and physical demand by over 50%, with users saving an average of 80.3% of their time when using it.</div></div>","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 2","pages":"Article 101897"},"PeriodicalIF":17.3,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599874","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}

However, the capacity to load these capsules with various substances and induce dynamic color-changing effects remains an unexplored area of research. Here, inspired by the color-changing abilities of tree frogs, we developed a dual-compartment composite microcapsule that responds to multiple stimuli. This microcapsule was fabricated by electrostatically adsorbing nanocapsules onto its surface, enabling full-spectrum color changes in response to UV light and temperature variations. By precisely regulating the number of nanocapsules on the surface of the composite microcapsules and adjusting the micro-nano-level coloration on individual composite microcapsules, a variety of stable and coordinated colors can be achieved. The microcapsules possess stable and fully reversible multicolored changing properties and can effectively be used as anti-counterfeiting inks in the screen-printing process. This advancement holds wide-ranging potential applications in the next generation of anti-counterfeiting labels and information encryption.</div></div>","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 2","pages":"Article 101925"},"PeriodicalIF":17.3,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816244","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}

Rationally designing plasmonic nanostructures requires understanding how particle geometry impacts hot carrier reaction dynamics. Here we use liquid-phase transmission electron microscopy (LP-TEM) and an electron radiolysis-resistant solvent to visualize hot carrier-mediated silver deposition and gold nanorod (AuNR) reshaping. AuNRs grew primarily in the transverse direction and displayed tip sharpening and preferential growth at LSPR hotspots. <em>Ex situ</em> white-light illumination produced similar morphological and compositional changes, whereas radiolysis products did not. Growth dynamics relative to electron beam flux and AuNR orientation were consistent with numerical simulations of hot carrier generation. Isolating hot carrier-induced redox processes on AuNRs during LP-TEM enabled quantifying spatially varying hot electron reaction dynamics. This approach is expected to enable quantifying and visualizing a broad range of plasmonic carrier-mediated reactions.</div></div>","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 2","pages":"Article 101912"},"PeriodicalIF":17.3,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763895","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}
