As the world transitions to green energy, there is a growing focus among many researchers on the requirement for high-efficient and safe batteries. Solid-state lithium metal batteries(SSLMBs) have emerged as a promising alternative to traditional liquid lithium-ion batteries(LIBs), offering higher energy density, enhanced safety, and longer lifespan. The rise of SSLMBs has brought about a transformation in energy storage, with aluminum(Al)-based material dopants playing a crucial role in advancing the next generation of batteries. The review highlights the significance of Al-based material dopants in SSLMBs applications, particularly its contributions to solid-state electrolytes(SSEs), cathodes, anodes,and other components of SSLMBs. Some studies have also shown that Al-based material dopants effectively enhance SSE ion conductivity, stabilize electrode and SSE interfaces, and suppress lithium dendrite growth, thereby enhancing the electrochemical performance of SSLMBs. Despite the above mentioned progresses, there are still problems and challenges need to be addressed. The review offers a comprehensive insight into the important role of Al in SSLMBs and addresses some of the issues related to its applications, endowing valuable support for the practical implementation of SSLMBs. 展开更多

Lithium-sulfur battery(LSB)has brought much attention and concern because of high theoretical specific capacity and energy density as one of main competitors for next-generation energy storage systems.The widely commercial application and development of LSB is mainly hindered by serious“shuttle effect”of lithium polysulfides(Li PSs),slow reaction kinetics,notorious lithium dendrites,etc.In various structures of LSB materials,array structured materials,possessing the composition of ordered micro units with the same or similar characteristics of each unit,present excellent application potential for various secondary cells due to some merits such as immobilization of active substances,high specific surface area,appropriate pore sizes,easy modification of functional material surface,accommodated huge volume change,enough facilitated transportation for electrons/lithium ions,and special functional groups strongly adsorbing Li PSs.Thus many novel array structured materials are applied to battery for tackling thorny problems mentioned above.In this review,recent progresses and developments on array structured materials applied in LSBs including preparation ways,collaborative structural designs based on array structures,and action mechanism analyses in improving electrochemical performance and safety are summarized.Meanwhile,we also have detailed discussion for array structured materials in LSBs and constructed the structure-function relationships between array structured materials and battery performances.Lastly,some directions and prospects about preparation ways,functional modifications,and practical applications of array structured materials in LSBs are generalized.We hope the review can attract more researchers'attention and bring more studying on array structured materials for other secondary batteries including LSB. 展开更多

LED背光技术不仅显著增强了LCD显示的动态范围,同时使现有图像达到了更逼真的显示效果。通过对LED单独控制,可为显示提供区域可控的LED背光。然而,LED之间的干扰在这里不仅仅为我们提供了较高的亮度,同时也是产生潜在虚假图像的原因,这使得导出最佳LED驱动信号成为一项具有挑战性的工作。本文通过两个数学模型:迭代解旋法和线性优化法,计算分析了上述问题。并给出了这两个数学模型的算法,同时建立了一个包含161个高动态范围图像的图像数据库,对上述两种方法的效果进行了评估。 展开更多

The liver is the central organ for digestion and detoxification and has unique metabolic and regenerative capacities.The hepatobiliary system originates from the foregut endoderm,in which cells undergo multiple events of cell proliferation,migration,and differentiation to form the liver parenchyma and ductal system under the hierarchical regulation of transcription factors.Studies on liver development and diseases have revealed that SRY-related high-mobility group box 9(SOx9)plays an important role in liver embryogenesis and the progression of hepatobiliary diseases.sox9 is not only a master regulator of cell fate determination and tissue morphogenesis,but also regulates various biological features of cancer,including cancer stemness,invasion,and drug resistance,making Sox9 a potential biomarker for tumor prognosis and progression.This review systematically summarizes the latest findings of sox9 in hepatobiliary development,homeostasis,and disease.We also highlight the value of sox9 as a novel biomarker and potential target for the clinical treatment of major liverdiseases. 展开更多

The objective of this study was to develop an effective,potential wound dressing,which was constructed with a composite hydrogel of poly(vinyl alcohol)(PVA),carboxymethyl chitosan(CMC)and tannic acid(TA)by cryogenic treatment and freeze-drying method.The as-prepared TA-crosslinked PVA/CMC hydrogels exhibited interconnected pore structure with the mean pore size of roughly 3.7𝜇m.We found that the compressive strength and stiffness of composite hydrogel increased when the TA component was introduced.However,the PVA/CMC-TA hydrogel possessed obviously lower swell property than that of the TA-free PVA/CMC hydrogel.We also found that the TA addition significantly improved the antibacterial capacity of the as-prepared hydrogel.Moreover,the inhibition zone test showed that the antibacterial activity of PVA/CMC-TA against S.aureus bacteria was greater than that against E.coli.The biological results indicated that the PVA/CMC-TA hydrogel exhibited good cytocompatibility to natural human dermal fibroblasts.In summary,our PVA/CMC-TA composite hydrogel exhibited promising mechanical and antibacterial properties,which showed great potential application as wound healing materials. 展开更多
