| 1 | Solid polymer electrolytes in all-solid-state lithium metal batteries:From microstructures to properties显示文摘All-solid-state lithium(Li)metal batteries(ASSLMBs)are considered one of the most promising secondary batteries due to their high theoretical capacity and high safety performance.However,low room-temperature ionic conductivity and poor interfacial stability are two key factors affecting the practical application of ASSLMBs,and our understanding of the mechanisms behind these key problems from microscopic perspective is still limited.In this review,the mechanisms and advanced characterization techniques of ASSLMBs are summarized to correlate the microstructures and properties.Firstly,we summarize the challenges faced by solid polymer electrolytes(SPEs)in ASSLMBs,such as the low roomtemperature ionic conductivity and the poor interfacial stability.Secondly,several typical improvement methods of polymer ASSLMBs are discussed,including composite SPEs,ultra-thin SPEs,SPEs surface modification and Li anode surface modification.Finally,we conclude the characterizations for correlating the microstructures and the properties of SPEs,with emphasis on the use of emerging advanced techniques(e.g.,cryo-transmission electron microscopy)for in-depth analyzing ASSLMBs.The influence of the microstructures on the properties is very important.Until now,it has been difficult for us to understand the microstructures of batteries.However,some recent studies have demonstrated that we have a better understanding of the microstructures of batteries.Then we suggest that in situ characterization,nondestructive characterization and sub-angstrom resolution are the key technologies to help us further understand the batteries'microstructures and promote the development of batteries.And potential investigations to understand the microstructures evolution and the batteries behaviors are also prospected to expect further reasonable theoretical guidance for the design of ASSLMBs with ideal performance. | Zongxi Lin Ouwei Sheng Xiaohan Cai Dan Duan Ke Yue Jianwei Nai Yao Wang Tiefeng Liu Xinyong Tao Yujing Liu | 2023 | Journal of Energy Chemistry2023，，6： | 1 |

| 3 | ^(131)I-chTNT-mediated radioimmunotherapy for non-uptaking ^(131)I pulmonary metastases from differentiated thyroid carcinoma显示文摘In this paper,the safety and efficacy of 131I-labeled mouse/human chimeric monoclonal antibody(131I-chTNT)-mediated radioimmunotherapy are evaluated because the patients have non-uptaking 131I pulmonary metastases from differentiated thyroid carcinoma(DTC).The 16 patients were injected intravenously by 29.6±3.7MBq·kg–1 using 131I-chTNT.The chest computer tomography was performed before treatment,as well as 28 and 70days after treatment.Responses and safety were assessed during the treatment.The results show that the 131I-chTNT infusion was well tolerated with the 12.5%complete response,18.8%partial response,25.0%progressive disease,and the 43.8%stable disease,indicating that most treatment-related adverse effects are mild transient and reversible.The131I-chTNT is promising for patients with non-uptaking the 131I pulmonary metastases from DTC. | GAO Shi JI Tiefeng WEN Qiang CHEN Bin MA Qingjie CHEN Zuowei LIU Lin | 2013 | Nuclear Science and Techniques2013，24，6： | 0 |
| 4 | Evolution features of in-situ permeability of low-maturity shale with the increasing temperature,Cretaceous Nenjiang Formation,northern Songliao Basin,NE China显示文摘Temperature-triaxial pressure permeability testing at the axial pressure of 8 MPa and confining pressure of 10 MPa,closed shale system pyrolysis experiment by electrical heating and scanning electron microscopy analysis are used to study the evolution mechanism of in-situ permeability in the direction parallel to bedding of low-maturity shale from Member 2(K_(2)n_(2))of Cretaceous Nenjiang Formation in northern Songliao Basin with mainly Type I kerogen under the effect of temperature.With the increasing temperature,the in-situ permeability presents a peak-valley-peak tendency.The lowest value of in-situ permeability occurs at 375℃.Under the same temperature,the in-situ permeability decreases with the increase of pore pressure.The in-situ permeability evolution of low-maturity shale can be divided into 5 stages:(1)From 25℃to 300℃,thermal cracking and dehydration of clay minerals improve the permeability.However,the value of permeability is less than 0.01×10^(-3)μm^(2).(2)From 300℃to 350℃,organic matter pyrolysis and hydrocarbon expulsion result in mineral intergranular pores and micron pore-fractures,these pores and fractures form an interconnected pore network at limited scale,improving the permeability.But the liquid hydrocarbon,with high content of viscous asphaltene,is more difficult to move under stress and more likely to retain in pores,causing slow rise of the permeability.(3)From 350℃to 375℃,pores are formed by organic matter pyrolysis,but the adsorption swelling of liquid hydrocarbon and additional expansion thermal stress constrained by surrounding stress compress the pore-fracture space,making liquid hydrocarbon difficult to expel and permeability reduce rapidly.(4)From 375℃to 450℃,the interconnected pore network between different mineral particles after organic matter conversion,enlarged pores and transformation of clay minerals promote the permeability to increase constantly even under stress constraints.(5)From 450℃to 500℃,the stable pore system and crossed fracture system in different bedding directions significantly enhance the permeability.The organic matter pyrolysis,pore-fracture structure and surrounding stress in the different stages are the key factors affecting the evolution of in-situ permeability. | HE Wenyuan MENG Qi'an LIN Tiefeng WANG Rui LIU Xin MA Shengming LI Xin YANG Fan SUN Guoxin | 2022 | Petroleum Exploration and Development2022，49，3： | 0 |
