In catalytic systems, however, competing pathways often respond differently to temperature, allowing the selective promotion of desired reactions while suppressing undesired ones through temperature modulation. Here we show that regulating the temperature near the freezing point of water can resolve the activity-stability trade-off in the oxygen evolution reaction on manganese dioxide. Although lowering the temperature decreases water oxidation rates, catalyst degradation through permanganate formation is suppressed more effectively, extending catalyst lifetime. Counterintuitively, further cooling below 0 °C accelerates permanganate formation, yielding an optimum temperature near 0 °C that balances activity and stability. This anti-Arrhenius behaviour, arising from electrolyte supercooling, is a rare example of anomalous temperature-dependent electrocatalysis under subzero conditions. Our findings highlight temperature regulation as a viable strategy for enhancing catalytic lifetime, with implications for electrochemical systems operating in wintertime and in polar and extraterrestrial environments.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":" ","pages":""},"PeriodicalIF":24.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149228313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collagen achieves this through conformational preorganization that translates local stereochemical information into homochiral triple helices, a level of hierarchical control rarely realized in artificial systems. Here we show that atomically precise Au4 nanoclusters encode local stereochemical information into a homochiral triple helix through a collagen-inspired assembly mechanism. A configuration-dependent endo-exo puckering of thiazolidine-2-thione ligands acts as a stereochemical switch, controlling metal-site exposure and biasing Au···Au metallophilic interactions. This intrachain preorganization fixes the torsional geometry of single helices, which then cooperatively braid into left-handed and right-handed triple helices, respectively. Systematic steric modulation redirects the assembly into alternative architectures, demonstrating programmable control over helicity. The triple-helical superstructures exhibit amplified chiroptical responses. These results establish a transferable molecular grammar for hierarchical helicity in metal nanoclusters and identify metallophilicity as a design principle for biomimetic materials.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":" ","pages":""},"PeriodicalIF":24.5,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A molecular motor is characterized by a set of low-energy states that differ in their configuration, that is, position or rotation. In biology and Feringa-type motors, unidirectional motion is driven by excitation of the molecule into a high-energy transitional state followed by a directional relaxation back to a low-energy state. Directionality is created by a steric hindrance to movement along one of the directions on the path from the excited state back to a low-energy state. Here we showcase a principal mechanism for the generation of unidirectional rotation of a molecule without the need for steric hindrance and transitional excited states. The chemical design of the molecule-consisting of a platform, an upright axle and a chiral rotor moiety-enables a rotation mechanism that relies on the transfer of orbital angular momentum from the driving current to the rotor. The transfer is mediated via orbital currents that are carried by helical orbitals in the axle.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":" ","pages":""},"PeriodicalIF":24.5,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tin is a promising anode material, due to its potential four-electron redox-active states and lack of dendrite formation. However, the irreversible electrochemical behaviour of the Sn4+/Sn2+ couple have limited high-capacity anode development. Here we achieve the reversible Sn4+/Sn2+ conversion, enabling a Sn4+/Sn0 anode for high-energy-density flow batteries. We accomplish this by adding iodide to highly soluble SnCl4 solutions at ratios that form SnCl62- and SnI62- intermediate complexes. SnI62- reduces reorganization energy during the electrochemical reaction of Sn4+/Sn2+, ensuring reversibility. SnCl62- imparts anolyte solubility. The redox peak potential difference decreased from 978 mV (Cl-) to 97 mV (I-), with a substantial decrease to the electron transfer impedance decrease. Coupled with Br-/Br2, the assembled full battery showed 89% energy efficiency at 40 mA cm-2, 227 Ah l-1 anolyte capacity and 205 Wh l-1 anolyte energy density. Based on these studies, we developed a kilowatt-scale stack that can operate stably for over 1,000 h.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":" ","pages":""},"PeriodicalIF":24.5,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149147995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
