Owing to the tremendous advantages and unique well-defined nanoscale structure,polyhedral oligomeric silsesquioxanes (POSS) have received considerable interest in the design of novel organic-inorganic hybrid nanomaterials with all manner of prominent capabilities,which is recognized as a new generation of promising materials for advanced applications of material science,engineering science and biomedical fields.Benefitting from the recent progress in combination of controlled/living polymerization and emerging click chemistry,POSS-based hybrid materials with ingenious design,versatile topological structure and sophisticated multifunctionality have been successfully fabricated and developed into abundant well-defined hybrid nanostructures with desired physicochemical properties.Tailor-made amphiphilic molecular design and nanosized hybrid architecture provide opportunities for the self-assembly of POSS-based hybrid materials with unique hierarchical morphologies in selective solvents.Through the in-depth understanding of structure-properties relationship,POSS-based hybrid materials can achieve the modulation of precise control of self-assembling process and multi-purpose applications with improved material performances.In this review,we summarize the recent advances of POSS-based hybrid materials in molecular design,self-assembly behavior in solutions and potential biomedical applications with main concerns on drug delivery,gene therapy,bioimaging and tissue engineering field.Finally,future directions and remaining challenges for further advancement of POSS-based hybrid materials are proposed and discussed.

在代持股权被名义股东的债权人申请强制执行时,隐名股东为实现投资权益显名化将自己变更为登记股东,在诉讼选择上,不应在执行异议之诉中一并提起股权确认之诉,而应先通过执行异议之诉排除强制执行,再提起股权变更之诉。隐名股东的股东资格认定应以区分说为标准,与外部关系无必然的联系。外部关系适用外观主义原则,名义股东的债权人属于《公司法》第32条第3款规定的“第三人”范畴,在隐名股东怠于消除股权登记不一致的权利外观且名义股东的债权人为善意时,隐名股东不能排除名义股东债权人的强制执行。

媒体化政治是政治过程依赖媒体技术予以展开的政治形态,具有政治过程依赖媒体予以展开、媒体逻辑影响政治逻辑、政治权力更接近于大众、形象政治成为政治过程的核心等四个基本特征。作为一种新型政治形态,媒体化政治虽然在促进政治民主化、提升政府能力、提高政治监督效能等各方面发挥着积极作用,但也存在对既有政治秩序的挑战、严重影响政治稳定和民主政治的健康发展等消极作用。

在家庭场景中,基于夫妻财产约定引致的股权“转让”,与交易场域下市场主体间的股权转让在目的、内容以及利益关系上均有本质区别。《民法典》婚姻财产制度与《公司法》固然在股权变动上存在规则适用之冲突,然而在解释论上亦有消解可能及可供遵循的合适路径。《公司法》第71条第2款限缩性解释,将股东配偶排除在外,不仅符合生活经验事实,而且在比较法上亦有先例可供遵循。除公司章程另有规定的外,基于夫妻财产约定的股权变动,不受其他股东同意权、优先购买权之制约,可以径自在夫妻间移转。然而基于债权形式主义之股权变动模式,股东及其配偶
