Garnet-type solid-state batteries(SSBs)are considered to be one of the most promising candidates to realize next-generation lithium metal batteries with high energy density and ***,the dendrite-induced short-circuit and the poor interfacial contact impeded the practical ***,interface engineering to achieve low interfacial resistance without high temperature calcination was developed,which Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZTO)was simply coated with complex hydride(Li_(4)(BH_(4))_(3)I(3L1L))in various mass ratios n(Li_(4)(BH_(4))_(3)I)-(100−n)LLZTO(10≤n≤40).The interfacial conductivity increases by more than three orders of magnitude from 8.29×10^(−6)S·cm^(−1)to 1.10×10^(−2)S·cm^(−1).Symmetric Li cells exhibit a high critical current density(CCD)of 4.0 mA·cm^(−2) and an excellent cycling stability for 200 h at 4.0 mA·cm^(−2).SSBs with polymeric sulfur-polyacrylonitrile(SPAN)cathode achieve a high discharge capacity of 1149 mAh·g^(−1) with a capacity retention of 91%after 100 cycles(0.2 C).This attempt guides a simple yet efficient strategy for obtaining a stable Li/LLZTO interface,which would promote the development of solid-state batteries.

Random change point model with an application to the China Household Finance Survey

引用

Science China Mathematics 2024年第10期67卷 2373-2386页

作者： Meng Li Lingxi Gao Guangming lv Xingwei tong School of Statistics Beijing Normal UniversityBeijing 100875China

We consider a linear model with a change point according to the unknown random threshold of a covariate. We give the expectation-maximization(EM) estimations of the regression and change point parameters. The existence of the random change point is detected by the supremum(SUP) test of score statistics. Theoretically, we establish the convergence and asymptotic distribution of the estimation and show that the EM estimates converge in distribution to a normal distribution. In addition, the numerical performance of the proposed approach is demonstrated through simulation studies. Finally, applying our methodology to household financial decisions, we see that the average debt tolerance of Chinese households is estimated to be 1.1364 times the sum of total household income and financial assets. The effect of assets and income on consumption shows a rapid decline if the household exceeds the average debt tolerance.

Photodynamic therapy(PDT) has garnered significant attention as a promising approach to cancer therapy, harnessing the combined benefits of localized light treatment and the accompanying host immune response. In this study, we engineered an immuno-enhanced PDT nanoplatform, denoted as HM@p-MOF(hybrid membrane@porphyrin-metal organic framework). The core porphyrin-MOF was cloaked with a hybrid membrane derived from B16F10 cancer cells and NK cells, resulting in enhanced stability. In both in vitro and in vivo experiments, our finding demonstrated that the hybrid membrane conferred dual targeting capabilities to the nanoplatform, leveraging the unique properties of the B16F10 membrane and NK membrane to augment immunogenic cell death(ICD) induced by photodynamic effects. Additionally,in conjunction with the immunomodulatory functions of the NK cell membrane, we observed an expansion of in situ immune infiltration leading to a systemic immune response. The HM@p-MOF nanoplatform exhibited the capacity to not only inhibit the growth of mouse melanoma but also suppress metastasis. This innovative HM@p-MOF nanoplatform present a viable strategy to enhance phototherapeutic efficacy for both localized and metastatic tumors. It provides a direction for the fabrication of biomimetic nanomedicines possessing immuno-modulatory function.
