Graphite has been regarded as the most important anode material for currently used lithium-ion batteries due to its two-dimensional (2D) nature hosting ionic intercalations. However, the kinetic insertion of Li ions is still not well known microscopically. In this work, we investigate the real-time intercalation process of Li ions using in situ transmission electron microscopy. We observe the lithium insertion process at the atomic scale, in which the graphite layers undergo expansion, forming w...

Abstract Nanomaterials comprising earth-abundant elements show great potential as substitutes for scarce, expensive materials in energy conversions, but degradation and contamination issues in working environments severely limit their practical applications. Here we report a facile and scalable strategy to synthesize ultrathin-graphene-coated cobalt nanoparticles which are achieved by the application of an electrical current pulse to a carbon-based substrate and by generating a transient high te...

In 2018, the myopia detection rate of children and adolescents aged 5-18 years old in Shaanxi Province was 54.9% (11 060/20 144). The myopia detection rate of girls [58.6%(5 830/9 949)] was higher than that of boys [58.6% (3 416/5 830)] (P 100 000 yuan was higherthan that of children and adolescents from regions with per capita GDP<50 000 yuan[OR (95%CI):1.58(1.34-1.87)].

Engineering strong metal–support interactions (SMSI) is an effective strategy for tuning structures and performances of supported metal catalysts but induces poor exposure of active sites. Here, we demonstrate a strong metal–support interaction via a reverse route (SMSIR) by starting from the final morphology of SMSI (fully-encapsulated core–shell structure) to obtain the intermediate state with desirable exposure of metal sites. Using core–shell nanoparticles (NPs) as a building block, the Pd–F...

Chemical design of multicomponent nanocrystals requires atomic-level understanding of reaction kinetics. Here, we apply single-particle imaging coupled with atomistic simulation to study reaction pathways and rates of Pd@Au and Cu@Au core-shell nanocubes undergoing oxidative dissolution. Quantitative analysis of etching kinetics using in situ transmission electron microscopy (TEM) imaging reveals that the dissolution mechanism changes from predominantly edge-selective to layer-by-layer removal o...

Summary The aprotic Li-CO2 battery with high energy density is an attractive energy-storage technology. However, its development is largely impeded by the sluggish kinetics of CO2 reduction and evolution reactions. Here, we demonstrate a class of ultrathin triangular RuRh alloy nanosheets as an exceptionally active catalyst for greatly accelerating the kinetics of CO2 reduction and evolution reactions and achieving a high-performance Li-CO2 battery. The RuRh alloy nanosheets-based battery can ac...

Abstract Two-dimensional (2D) ultrathin nanomaterials have shown extensive attention and potential biomedical applications in cancer theranostics. Herein, for the first time, we report the synthesis of monodisperse ultrathin lanthanum oxyiodide (LaOI) nanosheets with a thickness of merely 3 nm based on a facile wet chemistry strategy. By tuning the solvent composition and molar ratios of the precursors, we can modulate the shape and thickness of the nanosheets. Furthermore, a series of ultrathin...
