    Abstract: Nanocomposite solid polymer electrolytes are considered as a promising strategy for solid‐state lithium metal batteries (SSLMBs). However, the randomly dispersed fillers in the polymer matrix with limited Li + transference number and insufficient ionic conductivity severely sacrifice the ion transport capacity, thus restricting their practical application. To tackle these issues, a magnetic field‐assisted alignment strategy is proposed to disperse the vertically aligned akaganéite nanotube in the polymer matrix as an inorganic‐polymer nanocomposite solid‐state electrolyte for ultra‐stable SSLMBs. The metal cations as Lewis acid sites can grab anions to promote the dissociation of Li salts while the sufficient oxygen and hydroxyl functional group offer abundant Li‐ion migration sites for favored ion transportation. At the same time, the vertically aligned akaganéite/polymer interface combined with the above synergistic effects can establish oriented channels inside solid‐state electrolyte, which significantly elevates its ionic conductivity. Specially, an organic‐inorganic dual‐layer solid‐electrolyte interface is formed to uniform Li deposition and suppress the dendrite growth. The beneficial effect of the vertically aligned network is also demonstrated in full cell and pouch cell where remarkable 2000 cycles with a capacity decay of 0.012% per cycle can be achieved.

    Climatological influence of Eurasian winter surface conditions on the Asian and Indo‐Pacific summer circulation in the NCEP CFSv2 seasonal reforecasts

    Abstract: This study evaluates the possible influence of the winter surface conditions in Eurasia on the summer circulation over the Asian continent and Indo‐Pacific region. We have analysed multi‐seasonal ensemble reforecasts for 30 years (1979–2008) using the National Centers for Environmental Prediction Climate Forecast System version 2 initialized at the beginning of each month from January to May. It is found that the reforecasts initialized in winter (e.g., February) overestimate the snow cover fraction, depth and water equivalent, as well as surface albedo in the excessively snow‐covered portion of Eurasia from March to June. These biases are generated and perpetuated by a snow‐albedo feedback, leading to excessive upwards shortwave radiation reflected from the overly snow‐covered surface and an intense cold bias from the surface to mid‐troposphere. Originating over land, the cold bias is extended eastwards over the northwestern North Pacific by the advection of prevailing westerly winds. The cold air temperature in the broad mid‐latitude Asian‐Pacific region causes significantly lower geopotential heights at pressure levels in the middle and upper troposphere and thus increases the upper‐level westerly winds on its southern flank over the Asian continent and Indo‐Pacific. A slower than observed snow melting rate helps the winter cold bias persists well into the summer season in these runs. As a result, compared with the reforecasts initialized in spring (e.g., May), winter‐initialized reforecasts feature lower geopotential heights in the upper troposphere over Eurasia and a stronger subtropical jet over the Asian continent and the North Pacific from May to September, especially in early summer. The CFSv2 reforecasts in both sets of cases have too little total cloud fraction over Eurasia during June–August, leading to enhanced downwards shortwave radiation.

    Abstract: Circular RNAs (circRNAs) are a class of non‐coding RNAs that could serve as novel biomarkers for the diagnosis and treatment of diseases. We hypothesized that circRNAs of CD4 + T cells are involved in asthma. Objective In this study, we investigated the circRNA expression profile and the possible mechanism by which hsa_circ_0005519 participates in asthma. Methods The expression profiles of circRNAs in CD4 + T cells were revealed by circRNA microarray. Hsa_circ_0005519 expression in CD4 + T cells was confirmed in asthmatic patients (n = 65) and healthy subjects (n = 30). Hsa‐let‐7a‐5p, the target of hsa_circ_0005519, was predicted by online algorithms and verified by a dual‐luciferase reporter assay. Correlation assays between the expression of hsa_circ_0005519 and hsa‐let‐7a‐5p, the mRNA levels of interleukin (IL)‐13 and IL‐6 in CD4 + T cells, and the clinical characteristics of asthmatic patients were performed. The role of hsa_circ_0005519 in proinflammatory cytokine expression was investigated in CD4 + T cells from asthmatic patients in vitro . Hsa_circ_0005519 expression in PBMCs was determined in another cohort including 30 asthmatic patients and 24 controls. Correlation assays of hsa_circ_0005519 expressions between CD4 + T cells and PBMCs were performed. Results Hsa_circ_0005519 was up‐regulated and negatively correlated with hsa‐let‐7a‐5p expression in CD4 + T cells of asthmatic patients. Both the fraction of exhaled nitric oxide (FeNO) and the peripheral blood eosinophil ratio were positively correlated with hsa_circ_0005519 expression in CD4 + T cells. These outcomes were also different in asthmatic patients with low vs high hsa_circ_0005519 levels. Hsa_circ_0005519 expressions between CD4 + T cells and PBMCs were concordant in asthmatic patients. Mechanistically, hsa_circ_0005519 might bind to hsa‐let‐7a‐5p and relieve suppression for IL‐13/IL‐6 in CD4 + T cells. Conclusions and clinical relevance Our data suggest that hsa_circ_0005519 may induce IL‐13 and IL‐6 expression by regulating hsa‐let‐7a‐5p in CD4 + T cells to affect asthma. And hsa_circ_0005519 may be a potential biomarker of asthma.

    Vertical Growth of 2D Amorphous FePO 4 Nanosheet on Ni Foam: Outer and Inner Structural Design for Superior Water Splitting

    Abstract: Rational design of highly efficient bifunctional electrocatalysts based on 3D transition‐metal‐based materials for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is of great importance for sustainable energy conversion processes. Herein, a novel strategy involving outer and inner structural engineering is developed for superior water splitting via in situ vertical growth of 2D amorphous FePO 4 nanosheets on Ni foam (Am FePO 4 /NF). Careful experiments and density functional theory calculations show that the inner and outer structural engineering contributing to the synergistic effects of 2D morphology, amorphous structure, conductive substrate, and Ni−Fe mixed phosphate lead to superior electrocatalytic activity toward OER and HER. Furthermore, a two‐electrode electrolyzer assembled using Am FePO 4 /NF as an electrocatalyst at both electrodes gives current densities of 10 and 100 mA cm −2 at potentials of 1.54 and 1.72 V, respectively, which is comparable to the best bifunctional electrocatalyst reported in the literature. The strategies, introduced in the present work, may open new opportunities for the rational design of other 3D transition‐metal‐based electrocatalyst through an outer and inner structural control to strengthen the electrocatalytic performance.

    Abstract: Lithium‐rich layered oxides (LLOs) are concerned as promising cathode materials for next‐generation lithium‐ion batteries due to their high reversible capacities (larger than 250 mA h g −1 ). However, LLOs suffer from critical drawbacks, such as irreversible oxygen release, structural degradation, and poor reaction kinetics, which hinder their commercialization. Herein, the local electronic structure is tuned to improve the capacity energy density retention and rate performance of LLOs via gradient Ta 5+ doping. As a result, the capacity retention elevates from 73% to above 93%, and the energy density rises from 65% to above 87% for LLO with modification at 1 C after 200 cycles. Besides, the discharge capacity for the Ta 5+ doped LLO at 5 C is 155 mA h g −1 , while it is only 122 mA h g −1 for bare LLO. Theoretical calculations reveal that Ta 5+ doping can effectively increase oxygen vacancy formation energy, thus guaranteeing the structure stability during the electrochemical process, and the density of states results indicate that the electronic conductivity of the LLOs can be boosted significantly at the same time. This strategy of gradient doping provides a new avenue to improve the electrochemical performance of the LLOs by modulating the local structure at the surface.
