BackgroundEmerging evidence suggests that minimal acute kidney injury (stage 1 AKI) is associated with increased hospital mortality rates. However, for those who do not meet the AKI diagnostic criteria, whether a small increase in serum creatinine (SCr) levels is associated with an increased mortality rate in elderly patients is not known. Therefore, we aimed to investigate small elevations in SCr of lity of critically ill patients in the geriatric *** conducted a retrospective, observational, multicenter cohort study enrolling consecutive elderly patients (≥75 years) who received invasive MV from January 2008 to December 2020. Recursive partitioning was used to calculate the ratio of SCr rise from baseline within 48 h after MV and divided into six groups, (1) lity risk was found in this range. Clinical data and laboratory data were noted. Their general conditions and clinical characteristics were compared between the six groups. Prognostic survival factors were identified using Cox regression analysis. Kaplan–Meier survival analysis was employed for the accumulative survival *** total of 1292 patients (1171 men) with a median age of 89 (interquartile range: 85–92) with MV were suitable for further analysis. In all, 376 patients had any stage of early AKI, and 916 patients had no AKI. Among 916 non-AKI patients, 349 patients were in the ratio lity rates in the six groups from the lowest (<10%) to the highest (≥50%) were 8.0%, 16.8%, 28.4%, 54.4%, 80.0%, and 85.7%, respectively.

The solid electrolyte interphase（SEI） is widely recognized as a critical factor leading to the capacity fading of lithium-ion batteries（liBs）. Although SEI stress-related mechanical failure caused by the expansion or contraction of active materials upon cycles is well documented, previously reported SEI components and overpotential varying phenomena due to SEI stress and their effects on the electrochemical performance are poorly understood. Here, we establish a quantitative correlation between capacity fading and the SEI stress by considering its effects on side reactions, especially SEI component evolution, in a multiscale mechanical-electrochemical coupling model. Furthermore, the capacity fading behaviors of two typical cells（li[NiMnCo]O2as the cathode, and graphite and silicon as the anode, respectively） were adopted as numerical examples to demonstrate its potential utility and applications. Stress within the SEI was indeed found to play a predominant role in the capacity fading of the graphite and silicon anodes, resulting in 27% and 69% of the total capacity loss after 200 and 100 cycles at 1 C, respectively. This study provides valuable mechanical insights into the variations of SEI properties related to the capacity degradation and SEI optimization and design for liBs.

清末在河南洛阳出土了一方波斯国酋长阿罗憾墓志,该墓志被金石学家端方收藏。阿罗憾应是一位在中亚地区颇具声望的波斯国大酋长,亦或中亚某地的大酋长,因其与波斯关系密切或波斯曾据其地而被称为波斯国大酋长,目前并没有证据显示其为景教徒、波斯王室成员,抑或琐罗亚斯德教文献中救世主瓦赫兰(Bahram)的原型人物,但其部分事迹可能被瓦赫兰所吸收,当前学界对阿罗憾及其事迹存在过度解释之嫌。651年波斯灭亡后,阿罗憾致力于复兴波斯帝国,被召至唐廷,因其功绩,颇受优待,最终客死洛阳。《阿罗憾丘铭》为了解流亡波斯历史提供了珍贵信息,有助于认识彼时中国对波斯、中亚与阿拉伯人政策及其关系。

Solution processability is a unique property of organic semiconductors. The compact and regular π-π stacking between molecules is paramount in the performance of organic optoelectronic devices. However, it is still a challenge to improve their stacking quality without sacrificing the solution-processability from the aspect of materials design. Here, delicately engineered additives are presented to promote the formation of ordered aggregation of conjugated molecules by regulating their nucleation and growth dynamics. Intriguingly, the long-chain BTP-eC9-4F molecules can realize ordered aggregation comparable to short-chain ones without sacrificing processability. The domain size of BTP-eC9-4F aggregation is enlarged from 24.2 to 32.2 nm in blend *** exciton diffusion and charge transport become faster, contributing to the suppression of recombination losses. As a result, a power conversion efficiency of 19.2% is achieved in D18:BTP-eC9-4F based organic photovoltaics. Our findings demonstrate a facile strategy to improve the packing quality of solution-processed organic semiconductors for high-efficiency photovoltaics and beyond photovoltaics.

近年来,基于非富勒烯受体(NFAs)的有机太阳能电池(OSCs)取得了迅猛的发展。单异质结OSCs的光电转换效率(PCE)已突破19%,这进一步推动了有机光伏技术的商业化进程。光电转换效率的快速提升源于活性层材料的创新开发、器件工程的优化以及对器件物理的更深刻理解。然而,稳定性问题已成为制约其商业化的一个主要因素。目前,关于活性层材料和电池器件稳定性的研究仍相对有限。在本综述中,我们对NFA-OSCs不稳定性的机理进行了简要介绍,包括NFAs的光氧化降解、不稳定的共混薄膜形貌以及界面层诱导的NFAs不稳定性。同时,我们总结了近年来国内外关于提高NFA-OSCs稳定性的研究策略。期望本综述能为实现高效、稳定的NFA-OSCs提供有益的指导。
