  • Look beneath the surface
    Nat. Mater. (IF 38.663) Pub Date : 2020-09-21
    German Sastre

    Zeolitic catalyst particles are grown with nanosized fins that improve mass transport into the interior of the particle. This delays catalyst deactivation in the methanol-to-hydrocarbons process.

    The integrated in-plane growth of graphene nanoribbons (GNRs) and hexagonal boron nitride (h-BN) could provide a promising route to achieve integrated circuitry of atomic thickness. However, fabrication of edge-specific GNRs in the lattice of h-BN still remains a significant challenge.

    Recent progress in our understanding of the regulation of epithelial tissue stem cells has allowed us to exploit their abilities and instruct them to self-organize into tissue-mimicking structures, so-called organoids. Organoids preserve the molecular, structural and functional characteristics of their tissues of origin, thus providing an attractive opportunity to study the biology of human tissues

  • Applications and challenges of thermoplasmonics.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-17
    Guillaume Baffou,Frank Cichos,Romain Quidant

    Over the past two decades, there has been a growing interest in the use of plasmonic nanoparticles as sources of heat remotely controlled by light, giving rise to the field of thermoplasmonics. The ability to release heat on the nanoscale has already impacted a broad range of research activities, from biomedicine to imaging and catalysis. Thermoplasmonics is now entering an important phase: some applications

    Meteoritic diamonds and synthesized diamond-related materials contain a wide variety of complex nanostructures. This Comment highlights and classifies this structural complexity by a systematic hierarchical approach, and discusses the perspectives on nanostructure and properties engineering of diamond-related materials.

  • Solution processable metal-organic frameworks for mixed matrix membranes using porous liquids.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-10
    Alexander Knebel,Anastasiya Bavykina,Shuvo Jit Datta,Lion Sundermann,Luis Garzon-Tovar,Yury Lebedev,Sara Durini,Rafia Ahmad,Sergey M Kozlov,Genrikh Shterk,Madhavan Karunakaran,Ionela Daniela Carja,Dino Simic,Irina Weilert,Manfred Klüppel,Ulrich Giese,Luigi Cavallo,Magnus Rueping,Mohamed Eddaoudi,Jürgen Caro,Jorge Gascon

    The combination of well-defined molecular cavities and chemical functionality makes crystalline porous solids attractive for a great number of technological applications, from catalysis to gas separation. However, in contrast to other widely applied synthetic solids such as polymers, the lack of processability of crystalline extended solids hampers their application. In this work, we demonstrate that

  • The dose threshold for nanoparticle tumour delivery.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-10
    Ben Ouyang,Wilson Poon,Yi-Nan Zhang,Zachary P Lin,Benjamin R Kingston,Anthony J Tavares,Yuwei Zhang,Juan Chen,Michael S Valic,Abdullah M Syed,Presley MacMillan,Julien Couture-Senécal,Gang Zheng,Warren C W Chan

    Nanoparticle delivery to solid tumours over the past ten years has stagnated at a median of 0.7% of the injected dose. Varying nanoparticle designs and strategies have yielded only minor improvements. Here we discovered a dose threshold for improving nanoparticle tumour delivery: 1 trillion nanoparticles in mice. Doses above this threshold overwhelmed Kupffer cell uptake rates, nonlinearly decreased

  • Finned zeolite catalysts.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-10

    There is growing evidence for the advantages of synthesizing nanosized zeolites with markedly reduced internal diffusion limitations for enhanced performances in catalysis and adsorption. Producing zeolite crystals with sizes less than 100 nm, however, is non-trivial, often requires the use of complex organics and typically results in a small product yield. Here we present an alternative, facile approach

  • Predictive modelling of structure formation in semiconductor films produced by meniscus-guided coating.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-10
    Jasper J Michels,Ke Zhang,Philipp Wucher,Pierre M Beaujuge,Wojciech Pisula,Tomasz Marszalek

    Meniscus-guided coating methods, such as zone casting, dip coating and solution shearing, are scalable laboratory models for large-area solution coating of functional materials for thin-film electronics. Unfortunately, the general lack of understanding of how the coating parameters affect the dry-film morphology upholds trial-and-error experimentation and delays lab-to-fab translation. We present herein

  • Length scales of interfacial coupling between metal and insulator phases in oxides.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-10

    Controlling phase transitions in transition metal oxides remains a central feature of both technological and fundamental scientific relevance. A well-known example is the metal–insulator transition, which has been shown to be highly controllable. However, the length scale over which these phases can be established is not yet well understood. To gain insight into this issue, we atomically engineered

  • Chiral metal surfaces for enantioselective processes.
    Nat. Mater. (IF 38.663) Pub Date : 2020-08-03
    Nisha Shukla,Andrew J Gellman

    Chiral surfaces are critical components of enantioselective heterogeneous processes such as those used to prepare enantiomerically pure pharmaceuticals. While the majority of chiral surfaces in practical use are based on achiral materials whose surfaces have been modified with enantiomerically pure chiral adsorbates, there are many inorganic materials with valuable surface properties that could be

    Electrochemical capacitors can store electrical energy harvested from intermittent sources and deliver energy quickly, but their energy density must be increased if they are to efficiently power flexible and wearable electronics, as well as larger equipment. This Review summarizes progress in the field of materials for electrochemical capacitors over the past decade as well as outlines key perspectives

    Abdon Pena-Francesch,Huihun Jung,Melik C Demirel,Metin Sitti

    Self-healing materials are indispensable for soft actuators and robots that operate in dynamic and real-world environments, as these machines are vulnerable to mechanical damage. However, current self-healing materials have shortcomings that limit their practical application, such as low healing strength (below a megapascal) and long healing times (hours). Here, we introduce high-strength synthetic
