    26-37页
    查看更多>>摘要：Lithium(Li)metal anodes(LMAs)have garnered significant attention as a potential solution for develop-ing high-energy density batteries,given their theoretical specific capacity and redox potential.However,safety concerns and internal cycling stability issues originated from uncontrollable Li dendrite growth have impeded the practical application of LMAs.Probing the interface between Li metal and electrolyte is a crucial process that offers valuable insights into the characteristics and regularity of primary circular reactions.To illustrate the intrinsic characteristic of Li metal batteries(LMBs)in spatial and temporal,it is imperative to employ electron microscopes to characterize the structural components distribution of Li with atomic resolution.This paper summarizes the progress in the characterization and analysis of the interfaces in LMBs with electron microscopes based on the principles of electron-matter interac-tions.Finally,future trends and the potential of electron microscopes are also discussed to advance our understanding of LMBs.

    38-46页
    查看更多>>摘要：The microstructure of the active layer in organic photovoltaics(OPVs),such as the size of phase separa-tion,purity of the phases,and molecular packing within each phase,plays a crucial role in influencing the behavior of excitons and charge carriers within the active layer.It is also a key determinant of the photovoltaic performance of the device.During the optimization of OPV devices,the use of additives has been demonstrated to be an effective strategy in microstructure control,leading to enhanced per-formance.Therefore,the quest for stable and efficient novel additives,along with an exploration and summarization of the mechanisms underlying additive-induced microstructure control,is essential for a better understanding of the developmental trends of high-performance additives.In this review,we cat-egorize additives based on their chemical structures and discuss their effects on the microstructure of the active layer from both thermodynamic and kinetic perspectives.Furthermore,we elaborate on the working mechanisms and their impact on the photovoltaic performance of the devices.This review pro-vides an overview of recent advances in additives for OPVs,offering potential guidance for the future development of additives and further optimization of the active layer in photovoltaic devices.

    Stabilization and detection of labile reaction intermediates in supramolecular containers

    Rui WangYang LiangJulius Rebek Jr.Yang Yu...
    47-52页
    查看更多>>摘要：Detection and observation of reactive intermediates is an essential step in investigation of reaction path-ways.However,most reactive intermediates are unstable and present at low concentrations;their short lifetimes make them difficult to detect and characterize.Supramolecular containers offer opportunities for the stabilization and characterization of those labile species,through isolation from the media and protection inside the cavity of the host.In this review,we summarize the examples of labile reaction intermediates that are stabilized and characterized with the help of supramolecular containers.The con-tainer compounds include carcerands,deep cavitands and amide naphthotubes.We focus on unstable guest species-cyclobutadiene,benzocyclopropenone,o-benzyne,1,2,4,6-cycloheptatetraene,anti-Bredt's olefin,fluorophenoxycarbene,O-acylisoamide,and hemiaminal-that act as intermediates in certain or-ganic reactions.
