The(electro)chemical stability and Li dendrite suppression capability of sulfide solid electrolytes(SEs)need further improvement for developing all-solid-state Li batteries(ASSLBs).Here,we report advanced halogen-rich argyrodites via I and Cl co-occupation on the crystal ***,a proper I content forms a single phase,whereas an excessive I causes precipitation of two argyrodite phases like a superlattice *** resultant synergistic effect of the optimized composition allows to gain high ionic conductivities at room temperature and-20℃,and enhances the(electro)chemical stability against Li and Li dendrite suppression *** Li|argyrodite interface is very sensitive to the ratio of I and Cl.A LiCl-and LiI-rich double-layer interface is observed from the cell using the SE with optimized composition,whereas too high I content forms only a single interface layer with a mixture of Lil and *** double-layer interface is found to effectively mitigate the Li/SE *** proper designed argyrodite enables ASSLBs to achieve good electrochemical properties at a broad temperature range regardless of the electrode *** co-occupation strategy provides a novel exploration for advanced halogen-rich argyrodite system.

作者： Chao CHEN Yue ZHENG Yue zhang Xiao-hui LU cheng-jia SHANG Nuclear Equipment Division CNNC China Nuclear Power Engineering Co.Ltd. School of Materials Science and Engineering University of Science and Technology Beijing Nuclear and Radiation Safety Center MEP

Corrosion mechanism of automotive mufflers was investigated by SEM （scanning electron microscope） and XRD （X-ray diffractomer） analysis. 409L and newly developed 439M steels were evaluated in terms of condensate corrosion tests for 5 periods, 10 periods and 20 periods separately. The relative lifetimes of 409L and 439M steels were predicted according to the extreme value analysis method and pitting corrosion models. Modelling studies dem- onstrated that the predicted relative lifetime of 439M ferrite stainless steel is 6.8 times that of 409L steels. The extreme value analysis method was also successfully used in the road test. The estimated maximum corrosion depth of the 439M muffler is 0. 55 ram.

Collective flow and nuclear stopping in heavy ion collisions in Fermi energy domain

引用

Nuclear Science and Techniques 2018年第12期29卷 54-61页

作者： Peng-cheng Li Yong-Jia Wang Qing-Feng Li Hong-Fei zhang School of Nuclear Science and Technology Lanzhou University School of Science Huzhou University Institute of Modern Physics Chinese Academy of Sciences

The effects of the in-medium nucleon-nucleon(NN) elastic cross section on the observables in heavy ion collisions in the Fermi energy domain are investigated within the framework of the ultrarelativistic quantum molecular dynamics model. The results simulated using medium correction factors of F=σ_(NN)^(in-medium)/σ_(NN)^(free)=0.2,0.3,0.5,and the density-and momentum-dependent factor obtained from the FU3 FP1 parametrization are compared with the FOPI and INDRA experimental data. It is found that the calculations using the correction factors F=0.2 and 0.5 reproduce the experimental data(i.e.,collective flow and nuclear stopping) at 40 and 150 MeV/nucleon, respectively. Calculations with the FU3 FP1 parametrization can best fit these experimental data. These conclusions can be confirmed in both^(197)Au+^(197)Au and^(129)Xe+^(120)Sn.

The stability of the tribological properties of polymer coatings is vital to ensure their long term *** superlubricity of the poly(vinylphosphonic acid) (PVPA)-modified Ti6A14V/polytetrafluoroethylene (PTFE)interface can be obtained when lubricated by phosphate-buffered saline (PBS,pH =7.2),but not when lubricated by deionized water and ***,the mechanisms for the superlubricity of PVPA coatings affected by lubricant were investigated in *** stability of the PVPA coatings and their compatibility with the lubricant are critical factors in realizing ideal tribological properties of PVPA *** PVPA coatings are stable under a wide range of pH values (6-10) using PBS as the basic solution,and are also characterized by *** hydrolysis kinetics of phosphate anhydride is the main reason for the pH *** addition,along with stability,PVPA coatings exhibit different friction coefficients in salt solutions which are composed of various ions,which indicates that the compatibility between PVPA coatings and the lubricant can be used to regulate the superlubricity *** on a fundamental understanding of the mechanism of surperlubricity by considering the effects of the lubricant,PVPA coatings with stability and perfect tribological performance are expected to be applied in more aspects.

A reaction-difusion model with nonlinearity driven difusion

Applied Mathematics(A Journal of Chinese Universities) 2013年第3期28卷 290-302页

作者： MA Man-jun HU Jia-jia zhang Jun-jie TAO Ji-cheng Department of Mathematics College of Sciences China Jiliang University School of Mathematics and Physics University of South China

In this paper, we deal with the model with a very general growth law and an M- driven diffusion For the general case of time dependent functions M and #, the existence and uniqueness for positive solution is obtained. If M and # are T0-periodic functions in t, then there is an attractive positive periodic solution. Furthermore, if M and # are time-independent, then the non-constant stationary solution M（x） is globally stable. Thus, we can easily formulate the conditions deriving the above behaviors for specific population models with the logistic growth law, Gilpin-Ayala growth law and Gompertz growth law, respectively. We answer an open problem proposed by L. Korobenko and E. Braverman in [Can. Appl. Math. Quart. 17（2009） 85-104].

Expression of CDC42 in cervical squamous cell carcinoma and its correlation with clinicopathologic characteristics

引用

Chinese Journal of Cancer Research 2013年第6期25卷 656-661页

作者： Ding Ma Yuan cheng Youyi zhang Yanli Guo Zijian Li Geng Li Department of Gynecology and Obstetrics Peking University Third Hospital Institute of Vascular Medicine Peking University Third Hospital and Key Laboratory of Cardiovascular Molecular Biology and Regulatory PeptideMinistry of Health

Objective： The high expression of cell division cycle 42 protein （CDC42） may be involved in the occurrence and progression of several tumors. However, the expression and function of CDC42 in cervical squamous cell carcinoma remains unclear. This study aimed to investigate the expression of CDC42 in cervical squamous cell carcinoma and its correlation with clinicopathologic characteristics. Methods： The expression of CDC42 in 162 cervical squamous cell carcinoma tissue samples and 33 normal cervical tissue samples was investigated by immunohistochemistry. The CDC42 mRNA expression was detected by reverse transcription-polymerase chain reaction （RT-PCR）. Results： The cervical squamous cell carcinoma group showed a significantly higher CDC42 positive rate, compared to the normal cervical tissues （P〈0.05）. Fttrthermore, the tissues of stage Ⅱ-Ⅳ carcinoma patients showed higher CDC42 expression levels compared to stage I patients （P=0.05）. In addition, the expression of CDC42 was not correlated to age of patients, differentiation degree of cancer cells, or lymph node metastasis （P〉0.05）. Furthermore, compare with normal cervical tissues, the CDC42 mRNA expression in cervical cancer had no significant difference. Conclusions： CDC42 was up-regulated at protein level, but not mRNA level, in cervical squamous cell carcinoma. The high expression of CDC42 was correlated to the clinical stage of the patients, indicating that CDC42 might contribute to the progression of cervical squamous cell carcinoma.
