Liquid phase transmission electron microscopy reveals the growth pathway of 2D cobalt oxide and cobalt nickel oxide, in which 3D nanoparticles are formed first and then spread and transform into 2D nanosheets.
Local tuning of quantum dots embedded in a photonic waveguide can be achieved through the strain produced by laser heating of a thin layer of HfO2 deposited around the waveguide. The method is exploited to tune three quantum dots in resonance.
Subnanometre Pt clusters show high catalytic activity, but can sinter and so reduce reactivity. Here, authors localize Pt clusters in one zeolite channel, preventing sintering and allowing highly stable and selective catalytic propane dehydrogenation.
Generation of hydrogen peroxide from water and dioxygen is promising for artificial photosynthesis but photocatalysts suffer from low efficiency. Resorcinol–formaldehyde resins exhibit stable H2O2 generation with more than 0.5% solar-to-chemical conversion efficiency.
Low-dimensional tin-halide perovskites exhibit strong temperature dependence of luminescence decay time that translates into high sensitivity over a wide range of temperatures and as such can be used in high-resolution remote thermography.
Foreign body response can result in failure of biomaterials in vivo. Solvent-free crystals containing anti-fibrotic drugs now show the potential for long-term inhibition of fibrosis on a number of implantable devices in rodents and non-human primates.
Mobile micromachines with advanced configurations and functions self-assembled through designed dielectrophoretic interactions between structural and motor units.
High-throughput computation is especially useful for materials screening where synthesis is challenging. Here, it is used to construct a stability map of ternary nitrides, allowing discovery of stable compounds and providing insight into principles that govern nitride stability.
Scanning quantum dot microscopy, based on the use of a single molecule attached to the tip of the cantilever of an atomic force microscope, is shown to provide quantitative maps of surface potential distribution with atomic resolution.
Proton ceramic electrolysers can produce hydrogen directly from steam, but their development has suffered from limited electrical efficiency. A fully operational and stable BaZrO3-based tubular electrolyser with high hydrogen production rate is now reported.
Material depletion and accumulation at the crystallization front of organic semiconductors films induce the formation of large-area regular patterns, with a periodicity relevant to optoelectronic applications in the visible and near-infrared range.
An antisymmetric and chiral long range interlayer magnetic exchange interaction is measured, with implications for spintronics and chiral magnetic devices.
The mechanism of cytokinetic failure in the migrating zebrafish epicardium leading to multinucleated cells is shown to be driven by the interaction of the cytokinetic ring and the extracellular matrix through adhesion reinforcement by high traction forces.
Scanning electron nanobeam diffraction is used to monitor the morphology of organic thin films with nanometre resolution, revealing information on the arrangement of crystalline domains useful for structure–property relationship understanding.
Chemiluminescent molecular renal probes have been developed and are shown to be capable of non-invasive real-time imaging of early-stage oxidative stress biomarkers of drug-induced acute kidney injury, and high renal clearance.
Gold nanoparticles that passively deliver CRISPR machinery to blood repopulating cells have been developed and are shown to be capable of precise editing of multiple genetic loci of therapeutic interest without cytotoxicity or reduced fitness.
Crosstalk between microtubules and the actin cytoskeleton of cells is important in elucidating integrin-mediated adhesion and mechanotransduction. It is now shown that microtubule-mediated control of focal adhesions and podosomes occurs via KANK family proteins.
The Alx3 transcription factor, expressed in prenatal tooth development, is shown to revitalize adult progenitor cells in decellularized scaffolds, leading to enhanced parenchymal dental pulp and vascularized stroma regeneration in vivo.
