  • Cellular extrusion bioprinting improves kidney organoid reproducibility and conformation
    Nat. Mater. (IF 38.663) Pub Date : 2020-11-23

    Directed differentiation of human pluripotent stem cells to kidney organoids brings the prospect of drug screening, disease modelling and the generation of tissue for renal replacement. Currently, these applications are hampered by organoid variability, nephron immaturity, low throughput and limited scale. Here, we apply extrusion-based three-dimensional cellular bioprinting to deliver rapid and high-throughput

    Electrically conducting 2D metal–organic frameworks (MOFs) have attracted considerable interest, as their hexagonal 2D lattices mimic graphite and other 2D van der Waals stacked materials. However, understanding their intrinsic properties remains a challenge because their crystals are too small or of too poor quality for crystal structure determination. Here, we report atomically precise structures

    Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid to a strongly correlated two-dimensional electron system with properties that are extraordinarily sensitive to carrier density and to controllable environmental factors such as the proximity of nearby gates and twist-angle variation. Among other phenomena, magic-angle twisted bilayer graphene hosts superconductivity

    In recent years considerable progress has been made in the development of faithful procedures for the differentiation of human pluripotent stem cells (hPSCs). An important step in this direction has also been the derivation of organoids.

    Metallic nanoparticles have been used to harvest energy from a light source and transfer it to adsorbed gas molecules, which results in a reduced chemical reaction temperature. However, most reported reactions, such as ethylene epoxidation, ammonia decomposition and H–D bond formation are exothermic, and only H–D bond formation has been achieved at room temperature. These reactions require low activation

    Bioprinting promises enormous control over the spatial deposition of cells in three dimensions1,2,3,4,5,6,7, but current approaches have had limited success at reproducing the intricate micro-architecture, cell-type diversity and function of native tissues formed through cellular self-organization. We introduce a three-dimensional bioprinting concept that uses organoid-forming stem cells as building

  • Towards chirality control of graphene nanoribbons embedded in hexagonal boron nitride.
    Nat. Mater. (IF 38.663) Pub Date : 2020-09-21
    Hui Shan Wang,Lingxiu Chen,Kenan Elibol,Li He,Haomin Wang,Chen Chen,Chengxin Jiang,Chen Li,Tianru Wu,Chun Xiao Cong,Timothy J Pennycook,Giacomo Argentero,Daoli Zhang,Kenji Watanabe,Takashi Taniguchi,Wenya Wei,Qinghong Yuan,Jannik C Meyer,Xiaoming Xie

    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. Here we developed a two-step growth method and successfully achieved sub-5-nm-wide zigzag and armchair GNRs embedded

  • Towards a better understanding of Lewis acidic aluminium in zeolites.
    Nat. Mater. (IF 38.663) Pub Date : 2020-09-21
    Manoj Ravi,Vitaly L Sushkevich,Jeroen A van Bokhoven

    Zeolites are a class of materials that are of great relevance for industrial catalysis. Several fundamental questions relating to the structure and role of the Lewis acid sites in these materials remain unanswered. Proposals for the origin of such species can broadly be classified into three categories, which have distinct structures: extra-framework, framework-associated and framework aluminium. In

  • Entanglement and control of single nuclear spins in isotopically engineered silicon carbide.
    Nat. Mater. (IF 38.663) Pub Date : 2020-09-21

    Nuclear spins in the solid state are both a cause of decoherence and a valuable resource for spin qubits. In this work, we demonstrate control of isolated 29Si nuclear spins in silicon carbide (SiC) to create an entangled state between an optically active divacancy spin and a strongly coupled nuclear register. We then show how isotopic engineering of SiC unlocks control of single weakly coupled nuclear

  • Carbazole isomers induce ultralong organic phosphorescence.

    Chengjian Chen,Zhenguo Chi,Kok Chan Chong,Andrei S Batsanov,Zhan Yang,Zhu Mao,Zhiyong Yang,Bin Liu

    Commercial carbazole has been widely used to synthesize organic functional materials that have led to recent breakthroughs in ultralong organic phosphorescence1, thermally activated delayed fluorescence2,3, organic luminescent radicals4 and organic semiconductor lasers5. However, the impact of low-concentration isomeric impurities present within commercial batches on the properties of the synthesized

  • Electrochemical methods for determining ionic charge in solids.
    Nat. Mater. (IF 38.663) Pub Date : 2020-09-21
    Roger A De Souza,David N Mueller

    Classical experiments from solid-state electrochemistry can be used to determine the charge of ions in solids. This Comment also clarifies how the charge of point defects fits with the standard picture of ionic charge, and highlights differences between these electrochemical experiments and methods that probe electrons directly.

  • Mechanically robust lattices inspired by deep-sea glass sponges.
    Nat. Mater. (IF 38.663) Pub Date : 2020-09-21
    Matheus C Fernandes,Joanna Aizenberg,James C Weaver,Katia Bertoldi

    The predominantly deep-sea hexactinellid sponges are known for their ability to construct remarkably complex skeletons from amorphous hydrated silica. The skeletal system of one such species of sponge, Euplectella aspergillum, consists of a square-grid-like architecture overlaid with a double set of diagonal bracings, creating a chequerboard-like pattern of open and closed cells. Here, using a combination

  • Wnt-modified materials mediate asymmetric stem cell division to direct human osteogenic tissue formation for bone repair.

    The maintenance of human skeletal stem cells (hSSCs) and their progeny in bone defects is a major challenge. Here, we report on a transplantable bandage containing a three-dimensional Wnt-induced osteogenic tissue model (WIOTM). This bandage facilitates the long-term viability of hSSCs (8 weeks) and their progeny, and enables bone repair in an in vivo mouse model of critical-sized calvarial defects

  • Emergent phenomena and proximity effects in two-dimensional magnets and heterostructures.

    Ultrathin van der Waals materials and their heterostructures offer a simple, yet powerful platform for discovering emergent phenomena and implementing device structures in the two-dimensional limit. The past few years has pushed this frontier to include magnetism. These advances have brought forth a new assortment of layered materials that intrinsically possess a wide variety of magnetic properties

    Metal halide perovskites have shown promising optoelectronic properties suitable for light-emitting applications. The development of perovskite light-emitting diodes (PeLEDs) has progressed rapidly over the past several years, reaching high external quantum efficiencies of over 20%. In this Review, we focus on the key requirements for high-performance PeLEDs, highlight recent advances on materials

  • Mechanistic insights of evaporation-induced actuation in supramolecular crystals.

    Water-responsive materials undergo reversible shape changes upon varying humidity levels. These mechanically robust yet flexible structures can exert substantial forces and hold promise as efficient actuators for energy harvesting, adaptive materials and soft robotics. Here we demonstrate that energy transfer during evaporation-induced actuation of nanoporous tripeptide crystals results from the strengthening
