5Recent developments of aprotic lithium-oxygen batteries: functional materials determine the electrochemical performance显示文摘Lithium oxygen battery has the highest theoretical capacity among the rechargeable batteries and it can reform energy storage technology if it comes to commercialization. However,many critical challenges,mainly embody as low charge/discharge round-trip efficiency and poor cycling stability,impede the development of Li-O_2 batteries. The electrolyte decomposition,lithium metal anode corrosion and sluggish oxygen reaction kinetics at cathode are all responsible for poor electrochemical performances.Particularly,the catalytic cathode of Li-O_2 batteries,playing a crucial role to reduce the oxygen during discharging and to decompose discharge products during charging,is regarded as a breakthrough point that has been comprehensive investigated. In this review,the progress and issues of electrolyte,anode and cathode,especially the catalysts used at cathode,are systematically summarized and discussed.Then the perspectives toward the developments of a long life Li-O_2 battery are also presented at last.Xin Guo Bing Sun Dawei Su Xiaoxue Liu Hao Liu Yong Wang Guoxiu Wang 2017Science Bulletin2017,62,6:8
6Quality metrics and outcomes among critically ill patients in China:results of the national clinical quality control indicators for critical care medicine survey 2015-2019显示文摘Background:It is crucial to improve the quality of care provided to ICU patient,therefore a national survey of the medical quality of intensive care units(ICUs)was conducted to analyze adherence to quality metrics and outcomes among critically ill patients in China from 2015 to 2019.Methods:This was an ICU-level study based on a 15-indicator online survey conducted in China.Considering that ICU care quality may vary between secondary and tertiary hospitals,direct standardization was adopted to compare the rates of ICU quality indicators among provinces/regions.Multivariate analysis was performed to identify potential factors for in-hospital mortality and factors related to ventilator-associated pneumonia(VAP),catheter-related bloodstream infections(CRBSIs),and catheter-associated urinary tract infections(CAUTIs).Results:From the survey,the proportions of structural indicators were 1.83%for the number of ICU inpatients relative to the total number of inpatients,1.44%for ICU bed occupancy relative to the total inpatient bed occupancy,and 51.08%for inpatients with Acute Physiology and Chronic Health Evaluation II scores≥15.The proportions of procedural indicators were 74.37%and 76.60%for 3-hour and 6-hour surviving sepsis campaign bundle compliance,respectively,62.93%for microbiology detection,58.24%for deep vein thrombosis prophylaxis,1.49%for unplanned endotracheal extubations,1.99%for extubated inpatients reintubated within 48 hours,6.38%for unplanned transfer to the ICU,and 1.20%for 48-hour ICU readmission.The proportions of outcome indicators were 1.28‰for VAP,3.06‰for CRBSI,3.65‰for CAUTI,and 10.19%for in-hospital mortality.Although the indicators varied greatly across provinces and regions,the treatment level of ICUs in China has been stable and improved based on various quality control indicators in the past 5 years.The overall mortality rate has dropped from 10.19%to approximately 8%.Conclusions:The quality indicators of medical care in China’s ICUs are heterogeneous,which is reflected in geographic disparities and grades of hospitals.This study is of great significance for improving the homogeneity of ICUs in China.Xi Rui Fen Dong Xudong Ma Longxiang Su Guangliang Shan Yanhong Guo Yun Long Dawei Liu Xiang Zhou 2022Chinese Medical Journal2022,,9:4
7An infrastructure with user-centered presentation data model for integrated management of materials data and services显示文摘With scientific research in materials science becoming more data intensive and collaborative after the announcement of the Materials Genome Initiative,the need for modern data infrastructures that facilitate the sharing of materials data and analysis tools is compelling in the materials community.In this paper,we describe the challenges of developing such infrastructure and introduce an emerging architecture with high usability.We call this architecture the Materials Genome Engineering Databases(MGED).MGED provides cloud-hosted services with features to simplify the process of collecting datasets from diverse data providers,unify data representation forms with user-centered presentation data model,and accelerate data discovery with advanced search capabilities.MGED also provides a standard service management framework to enable finding and sharing of tools for analyzing and processing data.We describe MGED’s design,current status,and how MGED supports integrated management of shared data and services.Shilong Liu Yanjing Su Haiqing Yin Dawei Zhang Jie He Haiyou Huang Xue Jiang Xuan Wang Haiyan Gong Zhuang Li Hao Xiu Jiawang Wan Xiaotong Zhang 2021npj Computational Materials2021,,1:4
8Foraging habitat selection of overwintering Black-necked Cranes in the farming area surrounding the Caohai Wetland, Guizhou Province, China显示文摘Background: Understanding how overwintering birds choose foraging habitats is very important for conservation management. The overwintering Black-necked Crane(Grus nigricollis) feeds on crop remains in farmlands;thus, reasonable conservation management of this type of farmland that surrounds wetlands is critical for the overwintering populations of the Black-necked Crane;however, it is not clear how the Black-necked Crane chooses the foraging land in the farmland.Methods: A thorough field positioning survey of all foraging sites in farmland areas around the Caohai Wetland and a-sampling analysis of habitat selection by the Black-necked Crane were conducted during the winters from 20162017 and 2017-2018.Results: Multiple factors contributed to the selection of foraging habitat in farmlands, i.e., food factors(crop remains and tillage methods) > human disturbance factors(distance to road and settlement) > topography factors(slope aspect), listed according to the strength of influence. Additionally, Black-necked Cranes tend to choose farmland sites where there was no machine tillage, the crop remains were > 500 g/m^2, the distance to residences ranged from 100 to 500 m, the distance to roads ranged from 50 to 100 m, and the slopes exhibited western or eastern aspects. As the winters progressed, the volume of the edible crop remains declined, and the influences of the other main factors also changed, i.e., the factors of human disturbance(distance to road and settlement) became less important, while the effect of the food factor(crop remains) was strengthened. Thus, the foraging sites near the road became more important.Conclusion: The farming area surrounding the Caohai Wetland is very important for the overwintering Black-necked Crane. Food factors and human disturbance factors are the main factors that influence the choice of feeding ground.Dawei Wu Canshi Hu Mingming Zhang Zhumei Li Haijun Su 2020Avian Research2020,11,1:3
9A Vision of Materials Genome Engineering in China显示文摘In the new round of global scientific and technological revolution and industrial transformation,one of the biggest bottlenecks we are facing is the lack of adequate materials technology.It is urgently hoped that there can be a major revolution in the materials research and development(R&D)field,rather than gradual and slow development[1].Under this background,materials genome engineering(MGE)has been developing rapidly,and its key technologies and engineering applications have become the frontiers of materials research[2].Jianxin Xie Yanjing Su Dawei Zhang Qiang Feng 2022Engineering2022,8,3:3
10青海河湟谷地胃癌病理特征及其变化趋势分析(英文)显示文摘Objective: The aim of our study was to discuss changes in the clinicopathological characteristics of gastric cancer in Hehuang Valley of China in recent 10 years. Methods: A retrospective case-control study was performed on 2379 newly-diagnosed gastric cancer patients. All of them came from Hehuang Valley. The patients were divided into two groups [recent 5 years(R5Y) and late 5 years(L5Y)] from February 2003 to February 2013, and the clinicopathological data were surveyed retrospectively. Results: The constituent ratio of upper 1/3 gastric cancer in R5Y and L5Y was 33.5% and 20.7%, respectively, and it showed a significant difference between the two groups(χ2 = 21.28, P = 0.00). The constituent ratio of squamous carcinoma/adenosquamous carcinoma was 2.7% and 1.6%, respectively, and it also showed a significant difference between two groups(χ2 = 50.91, P = 0.00). The constituent ratio of moderately-poorly differentiated/poorly differentiated gastric carcinoma was 84.2% and 50.2%, respectively, and it showed statistically significant difference(χ2 = 30.28, P = 0.00). The detection rate of early gastric cancer(EGC) was 1.47%(35/2379). The constituent ratio of the types of Borrmann II and Borrmann IV of advanced gastric cancer(AGC) among 2379 cases was 47.6% and 40.8%, respectively, and that still showed statistically significant difference(χ2 = 18.80, P = 0.00). The constituent ratio of diffuse-type of gastric cancer in R5Y and L5Y was 36.2% and 30.8%, respectively, even there was a significant difference(χ2 = 7.49, P = 0.01). Furthermore, there were also significant differences in regional lymph nodes metastasis, perineural infiltration and vascular invasion(P < 0.05). The positive detection rate of HER2, ER and PR was 14.88%, 17.23% and 15.93%, respectively. The constituent ratio of HP in two groups was 43.8% and 36.2% respectively, and it also showed a significant difference(χ2 = 13.51, P = 0.00). Conclusion: The pathogenic sites in gastric cancer change to the upper stomach in Hehuang Valley in recent 10 years, and the detection rate of squamous carcinoma/adenosquamous carcinoma reveals a sharp rise. Borrmann III is still one of the main types of advanced gastric cancer, but the detection rates of Borrmann II and IV are increasing. The main type of gastric cancer is the intestinaltype, but the ratio of diffuse-type is also increasing in recent 10 years. The HP detection rate is 40.65%(967/2379), and it has a slight rise in recent 10 years. The detection rate of poorly differentiated adenocarcinoma is increasing despite the fact that the moderately/moderately-poorly differentiated adenocarcinoma is the main histologic types. High detection rates of lymph nodes metastasis, perineural infiltration and vascular invasion indicate poor prognosis in patients with gastric cancer. There is no change in HER2 positive rate, on the contrary, there are a little increase in ER and PR expression in Hehuang Valley.Su Yan Bin Li Junqi Wu Dawei Xie Yingcai Ma Yuanzhi Xiong Xuxiang Ma Xinjian Guo Man Dai Daquan Zhang Xinyang Liu 2014The Chinese-German Journal of Clinical Oncology2014,13,2:2
11Ameliorating the interfacial issues of all-solid-state lithium metal batteries by constructing polymer/inorganic composite electrolyte显示文摘Lithium metal is one of the most promising anodes for next-generation batteries due to its high capacity and low reduction potential.However,the notorious Li dendrites can cause the short life span and safety issues,hindering the extensive application of lithium batteries.Herein,Li_(7)La_(3)Zr_(2)O_(12)(LLZO)ceramics are integrated into polyethylene oxide(PEO)to construct a facile polymer/inorganic composite solid-state electrolyte(CSSE)to inhibit the growth of Li dendrites and widen the electrochemical stability window.Given the feasibility of our strategy,the designed PEO-LLZO-LiTFSI composite solid-state electrolyte(PLLCSSE)exhibits an outstanding cycling property of 134.2 mAh g^(-1) after 500 cycles and the Coulombic efficiency of 99.1%after 1000 cycles at 1 C in LiFePO_(4)-Li cell.When cooperated with LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2)(NCM622)cathode,the PLL-CSSE renders a capacity retention of 82.4%after 200 cycles at 0.2 C.More importantly,the uniform dispersion of LLZO in PEO matrix is tentative tested via Raman and FT-IR spectra and should be responsible for the improved electrochemical performance.The same conclusion can be drawn from the interface investigation after cycling.This work presents an intriguing solid-state electrolyte with high electrochemical performance,which will boost the development of all-solid-state lithium batteries with high energy density.Su Wang Qifang Sun Wenxiu Peng Yue Ma Ying Zhou Dawei Song Hongzhou Zhang Xixi Shi Chunliang Li Lianqi Zhang 2021Journal of Energy Chemistry2021,30,7:2
12Metal-Free 2D/2D van der Waals Heterojunction Based on Covalent Organic Frameworks for Highly Efficient Solar Energy Catalysis显示文摘Covalent organic frameworks(COFs)have emerged as a kind of rising star materials in photocatalysis.However,their photocatalytic activities are restricted by the high photogenerated electron-hole pairs recombination rate.Herein,a novel metal-free 2D/2D van der Waals heterojunction,composed of a two-dimensional(2D)COF with ketoenamine linkage(TpPa-1-COF)and 2D defective hexagonal boron nitride(h-BN),is successfully constructed through in situ solvothermal method.Benefitting from the presence of VDW heterojunction,larger contact area and intimate electronic coupling can be formed between the interface of TpPa-1-COF and defective h-BN,which make contributions to promoting charge car-riers separation.The introduced defects can also endow the h-BN with porous structure,thus providing more reactive sites.Moreover,the TpPa-1-COF will undergo a structural transformation after being integrated with defective h-BN,which can enlarge the gap between the conduction band position of the h-BN and TpPa-1-COF,and suppress electron backflow,corroborated by experimental and density functional theory calculations results.Accordingly,the resulting porous h-BN/TpPa-1-COF metal-free VDW heterojunction displays out-standing solar energy catalytic activity for water splitting without co-catalysts,and the H_(2) evolution rate can reach up to 3.15 mmol g^(−1) h^(−1),which is about 67 times greater than that of pristine TpPa-1-COF,also surpassing that of state-of-the-art metal-free-based photocatalysts reported to date.In particular,it is the first work for constructing COFs-based heterojunctions with the help of h-BN,which may provide new avenue for designing highly efficient metal-free-based photocatalysts for H_(2) evolution.Ge Yan Xiaodong Sun Yu Zhang Hui Li Hongwei Huang Baohua Jia Dawei Su Tianyi Ma 2023Nano-Micro Letters2023,15,9:2
13A functional hyperbranched binder enabling ultra-stable sulfur cathode for high-performance lithium-sulfur battery显示文摘Binders are of vital importance in stabilizing the cathodes to enhance the cycling stability of lithiumsulfur(Li-S) batteries. However, conventional binders are typically confronted with the drawback of inability for adsorbing lithium polysulfide(Li PS), thus resulting in severe active material losing and rapid capacity fading. Herein, a novel water-soluble hyperbranched poly(amidoamine)(HPAA) binder with controllable hyperbranched molecular structure and abundant amino end groups for Li-S battery is designed and fabricated, which can improve efficient adsorption for Li PS and stability of the sulfur cathodes. Besides, the strong intermolecular hydrogen bonds in HPAA binder can contribute to the structural stability of S cathode and integration of the conductive paths. Therefore, the Li-S battery with this functional binder exhibits excellent cycle performance with a capacity retention of 91% after 200 cycles at 0.1 C.Even at a high sulfur loading of 5.3 mg cm-2, a specific capacity of 601 mA h g-1 can also be achieved.Density functional theory(DFT) calculation further demonstrates that the enhanced electrochemical stability derives from the high binding energy between amino groups and LiP S and the wide electrochemical window(6.87 e V) of HPAA molecule. Based on the above all, this functional polymer will lighten a new species of binders for eco-friendly sulfur cathodes and significantly promote the practical applications of high-performance Li-S batteries.Xiang Luo Xianbo Lu Xiaodong Chen Ya Chen Chunyang Yu Dawei Su Guoxiu Wang Lifeng Cui 2020Journal of Energy Chemistry2020,29,11:2
14Filaments in high-speed counter-streaming plasma interactions driven by high-power laser pulses显示文摘Interactions of two counter-streaming plasmas driven by high power laser pulses are studied on Shenguang II laser facility.Filamentary structures were observed in the interaction region after the electrostatic shockwave decay.Theoretical analysis and observations indicate that the filaments are because of collisionless mechanisms,which are caused by the electromagnetic instability,such as the beam-Weibel instability.Collision experiments were also carried out for comparison and no filaments were generated.YUAN DaWei LI YuTong SU LuNing LIAO GuoQian YIN ChuanLei ZHU BaoJun ZHANG Jie 2013Science China(Physics,Mechanics & Astronomy)2013,56,12:2

16SPM-IS: An auto-algorithm to acquire a mature soybean phenotype based on instance segmentation显示文摘Mature soybean phenotyping is an important process in soybean breeding;however, the manual process is time-consuming and labor-intensive. Therefore, a novel approach that is rapid, accurate and highly precise is required to obtain the phenotypic data of soybean stems, pods and seeds. In this research, we propose a mature soybean phenotype measurement algorithm called Soybean Phenotype Measure-instance Segmentation(SPM-IS). SPM-IS is based on a feature pyramid network, Principal Component Analysis(PCA) and instance segmentation. We also propose a new method that uses PCA to locate and measure the length and width of a target object via image instance segmentation. After 60,000 iterations, the maximum mean Average Precision(m AP) of the mask and box was able to reach 95.7%. The correlation coefficients R^(2) of the manual measurement and SPM-IS measurement of the pod length, pod width, stem length, complete main stem length, seed length and seed width were 0.9755, 0.9872, 0.9692, 0.9803,0.9656, and 0.9716, respectively. The correlation coefficients R^(2) of the manual counting and SPM-IS counting of pods, stems and seeds were 0.9733, 0.9872, and 0.9851, respectively. The above results show that SPM-IS is a robust measurement and counting algorithm that can reduce labor intensity, improve efficiency and speed up the soybean breeding process.Shuai Li Zhuangzhuang Yan Yixin Guo Xiaoyan Su Yangyang Cao Bofeng Jiang Fei Yang Zhanguo Zhang Dawei Xin Qingshan Chen Rongsheng Zhu 2022The Crop Journal2022,10,5:2
