Potassium-ion batteries(PIBs)represent one of the most promising alternatives to lithium-ion batteries(LIBs),owing to their exceptional attributes such as high voltages,potent power capabilities,and cost-effectiveness.Nonetheless,challenges arise from the sluggish kinetics and significant volume expansion observed during the insertion/extraction of large-radii potassium ions,leading to subpar rate performance and considerable capacity degradation in potassium-ion batteries.Consequently,it becomes imperative to explore advanced anode materials exhibiting high electrochemical activity and robust structural stability.In this regard,the present review focuses on recent progress in metal-organic compounds(MOCs)as anode materials for potassium-ion batteries,systematically discussing their outstanding merits from the perspective of metal speciation.Additionally,the principal mechanism of K ion storage within relevant MOCs is presented.Furthermore,a comprehensive summary of existing drawbacks that hinder the broader application of MOCs-based materials is provided,along with proposed guidelines and strategies for addressing the inferior performance characteristics.This review serves to illuminate the development of MOCs-based anode materials for potassium-ion batteries and offers a valuable reference for future research endeavors.

Sora的虚拟(模拟)并非要制造虚假和非真实,亦非对人的智能与言行的仿真;相反,它具有“数学因素”,借助数据,以非人类(机器)的视角,揭示物理世界真实性被表征的另外一种可能。它表现为机器的知识生成性,影响和改变的却是人的认知能力与认知世界。Sora对媒介学的价值在于它揭示出人不再是认知世界唯一的、不可或缺的中介。“数字域”将独立于人这个中介,融合并超越人类经验,以另一种形式表征物理世界。它不仅延伸、侵蚀、融和人类通过语言建构的认知世界,也在建立一个以物的数据化和数据的物化为基础的新世界。Sora重现了柏拉图“洞穴寓言”的困境,重申了海德格尔对媒介“相合性”的追问。人类对真实性与正确性的追问,被数字召唤出来,人类认知面临数字技术的洗礼和检验。数字建构的认知世界将与人类已有认知世界相对应、相冲突、相验证、相独立、相形塑。这场对媒介真实性与正确性的追问即是世界性的,又是地域性的,更是人类个体性的;它将全面引爆人类认知向数据转向的革命,带来人类历史上最伟大、最广泛、最深刻、最持久的认知战,重塑人类整体认知和我们每一个人的认知。

The strong aggregation tendency of hole transport material poly[3-(4-carboxylbutyl)thiophene-K(P3CT-K)restricts its further application in inverted perovskite solar cells(PSCs).Here,we report an effective strategy to address this issue and achieve the superior performance of inverted methylammonium lead triiodide(MAPbI3)PSCs,in which graphdiyne oxide(GDYO)doped P3CT-K nanocomposites are applied as the hole transport nanolayer(HTL).It is revealed that the strongπ–πstacking interaction occurs between GDYO and P3CT-K,which is proved by the blue shift of the absorption peak of P3CT-K nanolayer.The aggregation control via GDYO contributes to the property improvement of P3CT-K HTL.Moreover,the homogeneous coverage induces the growth of perovskite grain with larger size than that based on the undoped one.As a result,the optimized surface morphology,enhanced conductivity,charge extraction as well as better crystal quality,finally improve the device performance.An optimal power conversion efficiency of 19.06%is achieved,with simultaneously improved fill factor and short circuit current density.This work presents the potential of functional graphdiyne(GDY)in the development of highly efficient photovoltaic device.

Water splitting is important to the conversion and storage of renewable energy,but slow kinetics of the oxygen evolution reaction(OER)greatly limits its utility.Here,under visible light illumination,the p-n WO_(3)/SnSe_(2)(WS)heterojunction significantly activates OER catalysis of CoFe-layered double hydroxide(CF)/carbon nanotubes(CNTs).Specifically,the catalyst achieves an overpotential of 224 mV at 10 mA cm^(-2)and a small Tafel slope of 47 mV dec^(-1),superior to RuO_(2)and most previously reported transition metal-based OER catalysts.The p-n WS heterojunction shows strong light absorption to produce photogenerated carriers.The photogenerated holes are trapped by CF to suppresses the charge recombination and facilitate charge transfer,which accelerates OER kinetics and boost the activity for the OER.This work highlights the possibility of using heterojunctions to activate OER catalysis and advances the design of energy-efficient catalysts for water oxidation systems using solar energy.

Coupled with intricate regional interactions, the provincial disparity of energy-resource endowment and other economic conditions in China have created spatially complex energy consumption patterns that require analyses beyond the traditional ones. To distill the spatial effect out of the resource and economic factors on China＇s energy consumption, this study recast the traditional econometric model in a spatial context. Several analytic steps were taken to reveal different aspects of the issue. Per capita energy consumption （AVEC） at the provincial level was first mapped to reveal spatial clusters of high energy consumption being located in either well developed or energy resourceful regions. This visual spatial autocorrela- tion pattern of AVEC was quantitatively tested to confirm its existence among Chinese provinces. A Moran scatter- plot was employed to further display a relatively centralized trend occurring in those provinces that had parallel AVEC, revealing a spatial structure with attraction among high-high or low-low regions and repellency among high-low or low-high regions. By a comparison between the ordinary least square （OLS） model and its spatial econometric counterparts, a spatial error model （SEM） was selected to analyze the impact of major economic determinants on AVEC. While the analytic results revealed a significant positive correlation between AVEC and economic development, other determinants showed some intricate influential patterns. The provinces endowed with rich energy reserves were inclined to consume much more energy than those otherwise, whereas changing the economic structure by increasing the proportion of secondary and tertiary industries also tended to consume more energy. Both situations seem to underpin the fact that these provinces were largely trapped in the economies that were supported by technologies of low energy efficiency during the period, while other parts of the country were rapidly modernized by adopting advanced technologies and more efficient industries.

共建“一带一路”倡议提出十年来,作为与“一带一路”具有极高耦合关联度的高职教育,其国际化发展成就卓著:中外合作办学洼地拓荒,高地崛起;国际人才培养宏微兼具,特色鲜明;对外教育服务联盟聚力,抱团出海;职教品牌输出多维有为,量质齐升。但是,深度审视后发现,高职教育国际化发展仍存在一些问题,主要表现为:办学结构不良,合作办学未能跟上经济社会新的开放态势;供需匹配不够,高技能人才培养未能满足“一带一路”建设需求;校企合作不足,产业和教育国际化发展未能实现同频共振。未来高职教育要对接供需两端,践行双循环供需平衡的国际化发展路向;深化产教融合,开拓国际化发展的新航道;聚焦数字赋能,打造新时代高职教育国际化的金字招牌。

·AIM: To compare posterior capsule opacification(PCO)degree and visual functions after phacoemulsification in eyes implanted with 360-degree square edge hydrophilic acrylic intraocular lens(IOL)(570C C-flex, Rayner) and sharp edge hydrophobic acrylic IOL(Sensar AR40 e,AMO) in diabetic patients.· METHODS: Sixty diabetic patients underwent uneventful phacoemulsification and randomly implanted one of the two IOLs. The PCO value was measured by retroillumination photographs and Evaluation of Posterior Capsule Opacification(EPCO) 2000 image-analysis software at 1, 6, 12, and 24 mo after surgery. Visual acuity, and contrast sensitivity in photopic and mesopic conditions were also examined at each follow up time point. The incidence of eye that required Nd:YAG laser posterior capsulotomy were also compared.·RESULTS: There was not any statistically significant difference in PCO scores between Rayner C-flex 570 C group and Sensar AR40 e group at each follow up time point. Visual acuity, Nd:YAG capsulotomy incidence and contrast sensitivity also had no significant difference during the 24 mo follow-up.·CONCLUSION: For diabetic patients, Rayner 570 C Cflex and Sensar AR40 e IOLs are same effective for prevent PCO. The 360-degree square edge design maybe is a good alternative technique to improve PCO prevention.

The outbreak of coronavirus disease 2019(COVID-19)is a significant challenge for clinicians,especially for immunocompromised cancer patients.By analyzing the impact of COVID-19 on the immune microenvironment of colorectal cancer(CRC)patients at the tissue level and single-cell level,we found that CRC patients are more easily infected by severe acute respiratory syndrome coronavirus-2(SARSCoV-2),but promotion of infiltration and differentiation of monocytes makes them more likely to develop severe COVID-19.Because of the continuing activation of nuclear factor(NF)-κB and C-C chemokine receptor type 5(CCR5)signaling pathways in monocytes,imbalance of macrophage polarization can aggravate the cytokine release syndrome.Therefore,regulating the infiltration and differentiation of monocytes is helpful for the treatment of COVID-19 in CRC patients.
