《公司法司法解释五》第三条规定了董事职务任期届满前的无因解除与离职补偿规则,设计该制度的目的在于保护中小投资者利益及优化营商环境。研究发现,相关条文的规范教义性质不清,缺乏系统性董事离职补偿的实体和程序规范,制度落地存在困难。在实践中,司法判例和公司章程均存在对制度的异化处理。为应对上述理论和实践困境,董事离职补偿制度的构建应当正本清源,守正出新。在理念上,应当在厘清不同董事与公司法律关系的基础上构建规则,搭建起以无因解任制度为基础的董事离职补偿实体和程序规则,一方面促进公司利益平衡和实现公司治理目标,另一方面也为营商环境法治化提供有力支撑。

The high content of aluminum(Al)impurity in the recycled cathode powder seriously affects the extraction efficiency of Nickel,Cobalt,Manganese,and lithium resources and the actual commercial value of recycled materials,so Al removal is crucially important to conform to the industrial standard of spent li-ion battery cathode *** this work,we systematically investigated the leaching process and optimum conditions associated with Al removal from the cathode powder materials collected in a wet cathode-powder peeling and recycling production line of spent li-ion batteries(liBs).Moreover,we specifically studied the leaching of fluorine(F)synergistically happened along with the removal process of Al,which was not concerned about in other studies,but one of the key factors affecting pollution prevention in the recovery *** mechanism of the whole process including the leaching of Al and F from the cathode powder was indicated by using NMR,FTIR,and XPS,and a defluoridation process was preliminarily investigated in this *** leaching kinetics of Al could be successfully described by the shrinking core model,controlled by the diffusion process and the activation energy was 11.14 kJ/***,the leaching of F was attributed to the dissolution of liPF6and decomposition of PVDF,and the kinetics associated was described by Avrami *** interaction of Al and F is advantageous to realize the defluoridation to some *** is expected that our investigation will provide theoretical support for the large-scale recycling of spent liBs.

One intrinsic yet critical issue that troubles the field of fluorescence microscopy ever since its introduction is the unmatched resolution in the lateral and axial directions(i.e.,resolution anisotropy),which severely deteriorates the quality,reconstruction,and analysis of 3D volume *** leveraging the natural anisotropy,we present a deep self-learning method termed Self-Net that significantly improves the resolution of axial images by using the lateral images from the same raw dataset as rational *** incorporating unsupervised learning for realistic anisotropic degradation and supervised learning for high-fidelity isotropic recovery,our method can effectively suppress the hallucination with substantially enhanced image quality compared to previously reported *** the experiments,we show that Self-Net can reconstruct high-fidelity isotropic 3D images from organelle to tissue levels via raw images from various microscopy platforms,e.g.,wide-field,laser-scanning,or super-resolution *** the first time,Self-Net enables isotropic whole-brain imaging at a voxel resolution of 0.2×0.2×0.2μm^(3),which addresses the last-mile problem of data quality in single-neuron morphology visualization and reconstruction with minimal effort and ***,Self-Net is a promising approach to overcoming the inherent resolution anisotropy for all classes of 3D fluorescence microscopy.

契约式股权是当今经济转型背景下由商事实践推动产生的以合同之名解构股权的制度安排。面对在全球蓬勃四起的契约式股权类型,我国公司法面临着束手无策的调整困境,形成了行政与司法侵蚀立法的尴尬局面。作为契约法侵入组织法的产物,契约式股权颠覆了“一股一权”理念,引发了公司法与合同法适用顺位之争,并加剧了公司法与金融监管法的法益冲突。从理论根源上看,公司法对契约式股权结构调整的失败与其自身偏安自治型法范式、恪守部门法学思维、依赖法律移植路径密不可分。在当前公司法修改之际,应以功能主义、整体主义、本土化理念打造具有回应型品格的公司法,以包容和开放的态度回应契约式股权的法治化需求。

通过组织形貌观察及蠕变曲线测定,研究了一种含Re镍基单晶合金在高温的蠕变行为。结果表明,合金经完全热处理后的组织结构是立方γ′相以共格方式嵌镶在γ基体中。在试验的温度和应力范围内,与无Re合金相比较,含Re合金有较好的蠕变抗力及较长的蠕变寿命,并测算出合金在稳态期间的蠕变激活能与应力指数。通过分析位错攀移越过筏状γ′相及影响合金应变速率的因素,研究了合金在稳态蠕变期间的变形机制,其中,元素Re溶入γ基体后可有效阻碍位错运动,降低合金的应变速率,是使合金具有较低应变速率和较长蠕变寿命的主要原因。

Anode-free solid-state lithium metal batteries(AF-SSLBs)have the potential to deliver higher energy density and improved safety beyond lithium-metal ***,the unclear mechanism for the fast capacity decay in AF-SSLBs,either determined by dead li or solid electrolyte interface(SEI),limits the proposal of effective strategies to prolong cycling *** clarify the underlying mechanism,herein,the evolution of SEI and dead li is quantitatively analyzed by a solid-state nuclear magnetic resonance(ss-NMR)technology in a typical liPF6-based polymer *** results show that the initial capacity loss is attributed to the formation of SEI,while the dead li dominates the following capacity loss and the growth rate is 0.141 mA h cm^(−2)cycle−*** reduce the active li loss,the combination of inorganic-rich SEI and self-healing electrostatic shield effect is proposed to improve the reversibility of li deposition/dissolution behavior,which reduces the capacity loss rate for the initial SEI and following dead li generation by 2.3 and 20.1 folds,*** a result,the initial Coulombic efficiency(ICE)and stable CE increase by 15.1%and 15.3%in li-Cu cells,which guides the rational design of high-performance AF-SSLBs.

Due to ever-increasing concerns about safety issues in using li ionic batteries,solid electrolytes have extensively *** li-rich antiperovskite li_(3)OBr has been considered as a promising solid electrolyte candidate,but it still suffers challenges to achieve a high ionic conductivity owing to the high intrinsic symmetry of the crystal ***,we presented a design strategy that introduces various point defects and grain boundaries to break the high lattice symmetry of li_(3)OBr crystal,and their effect and microscopic mechanism of promoting the migration of li-ion were explored *** has been found that li_(i)are the dominant defects responsible for the fast li-ion diffusion in bulk li_(3)OBr and its surface,but they are easily trapped by the grain boundaries,leading to the annihilating of the Frenkel defect pair V'_(li)+li_(i),and thus limits the V'_(li)diffusion at the grain *** V_(Br)defect near the grain boundaries can effectively drive V'_(li)across the grain boundary,thereby converting the carrier of li^(+)migration from li,in the bulk and surface to V'_(li)at the grain boundary,and thus improving the ionic conductivity in the whole li_(3)OBr *** work provides a comprehensive insight into the li^(+)transport and conduction mechanism in the li_(3)OBr *** opens a new way of improving the conductivity for all-solid-state li electrolyte material through the defect design.
