Despite the successful synthesis of numerous MXenes, a family of 2D transition-metal carbides and nitrides, experimental isolation of 2D Cr2C sheets has remained elusive. Here we demonstrate that Cr2C sheets can be obtained from Cr2AlC by selectively extracting the Al layer using aqueous phosphoric acid followed by liquid-phase delamination. The weak phosphoric acid suppresses rapid dissolution of both Al and Cr while enabling preferential extraction of Al through selective coordination with dissolved Al3+ species into soluble complexes. Unlike previously reported MXenes that typically possess surface-passivating terminations, this approach yields 2D Cr2C with largely clean, unpassivated surfaces, which remain stable even after prolonged exposure to air, water or heat. Monolayer Cr2C is characterized by unusual Dirac half-semimetal property, featuring a 2.0-eV band gap in the spin-down channel and Dirac semimetal cone in the spin-up channel. Notably, this Dirac semimetal feature is retained in few layers. Benefiting from its chemically robust clean surface and high Fermi velocity, 2D Cr2C exhibits electrical conductivity surpassing titanium carbide. Two-dimensional chromium carbide (Cr2C) has interesting predicted properties but experimental isolation remains challenging. Here Cr2C sheets are obtained from Cr2AlC by selective extraction of the Al layer using aqueous phosphoric acid, followed by a liquid-phase delamination step. Monolayer Cr2C displays an unusual Dirac half-semimetal property.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"5 10","pages":"1648-1657"},"PeriodicalIF":22.6,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148291103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, limited progress has been made in engineering formatotrophy in yeasts, and no yeasts grow using formate naturally. Here we use metabolic modelling to find two potential formatotrophy pathways in Yarrowia lipolytica. We then use C13 tracer analysis and computationally guided growth experiments to show that wild-type Y. lipolytica possesses strong formate dissimilation and a cyclical C1 pathway with similar architecture to the synthetic serine–threonine cycle, which it uses to co-assimilate formate and glycerol. Messenger RNA sequencing shows that formate exposure results in increased oxidative stress and changes in the tricarboxylic acid cycle, redox and C1 metabolism. Following this, we use model-guided adaptive laboratory evolution to produce a formatotrophic strain of Y. lipolytica using the eukaryotic serine–threonine cycle. We then use further messenger RNA sequencing to show that formatotrophy is supported by changes in adenosine triphosphate and reactive oxygen species metabolism. Subsequently, we engineer nicotinamide adenine dinucleotide phosphate (NADPH) and reactive oxygen species metabolism to create a strain with substantially improved growth. This strain reaches about 10% of the theoretical maximum biomass yield, highlighting its potential for additional engineering approaches. Finally, we show that beta-carotene production from formate is possible in our engineered strain, opening the door to formatotrophic eukaryote bioprocesses. Yarrowia lipolytica is a non-model yeast of considerable industrial interest. Here metabolic modelling and directed evolution are used to create a strain of Y. lipolytica that is able to grow on formate as a step towards electrical CO2-based bioprocesses based on a complex metabolic pathway.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"5 9","pages":"1360-1373"},"PeriodicalIF":22.6,"publicationDate":"2026-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44160-026-01076-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solid-state hydrogen-driven redox reduction is not only a sustainable alternative, but can also be used to integrate reduction, in situ alloying of mixed oxides and microstructure design in one single process. Upon co-reduction of a Fe2O3–NiO mixture with hydrogen, we report a distinct type of solid–solid catalytic interaction between pre-reduced metal (Ni) and a transient oxide (FeO). This interaction accelerates hydrogen-based reduction by a factor of at least two, highlighting its potential relevance for improving reduction kinetics in hydrogen-based ironmaking and alloy production. Specifically, during hydrogen-driven co-reduction of Fe2O3 and NiO, Ni partitioning takes place across metal–oxide interfaces, driven by interface dynamics, during which restructuring continuously regenerates the catalytic sites that promote H2 spillover. These findings show that hydrogen-based alloy production is not only more sustainable than fossil-based practices, but can leverage kinetic and commercial advantages through solid–solid catalytic effects. This study uncovers a solid–solid catalytic effect for the hydrogen-based reduction of oxide mixtures. This effect increases reaction rates and enables sustainable master alloy production by integrating reduction and alloying within a single process.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"5 9","pages":"1340-1348"},"PeriodicalIF":22.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44160-026-01086-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report a rapid (≤5 min) soak-coating strategy for self-assembled monolayer fabrication, enabled by molecular design and solvent engineering. The unsymmetric self-assembled monolayer material (4-(10-methoxy-7H-benzo[c]carbazol-7-yl)phenyl)phosphonic acid was rationally designed with dual-functional molecular segments to inhibit molecular aggregation in solution and enhance interfacial charge transport. Concurrently, an ethanol-based solvent system containing 1.5 vol% water was engineered to improve material dispersity and strengthen surface anchoring on transparent conducting oxide substrates. The soak-coated self-assembled monolayers exhibit dense and uniform coverage, yielding perovskite solar cells with a certified power conversion efficiency of 27.23%. This methodology demonstrates good scalability, successfully extending to large-area devices, mini-modules and flexible architectures, all of which maintain stable operation. Notably, both the soak-coating solutions and modified transparent conducting oxide substrates can be reused, substantially improving resource efficiency. This work provides a scalable and cost-efficient route for fabricating stable perovskite solar cells. The use of self-assembled monolayers (SAMs) as interfacial hole-selective layers is a key technological enabler for perovskite solar cells (PSCs), but scalable fabrication remains challenging. Here a 5-min soak-coating protocol is developed through SAM molecular design and hydrogen-bond-mediated solvent engineering. High-density monolayers are produced, enabling scalable production of high-efficiency, large-area PSCs.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"5 10","pages":"1612-1622"},"PeriodicalIF":22.6,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149126010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
