1Si-Based Anode Materials for Li-Ion Batteries:A Mini Review显示文摘Si has been considered as one of the most attractive anode materials for Li-ion batteries(LIBs) because of its high gravimetric and volumetric capacity. Importantly, it is also abundant, cheap, and environmentally benign. In this review, we summarized the recent progress in developments of Si anode materials. First, the electrochemical reaction and failure are outlined, and then, we summarized various methods for improving the battery performance, including those of nanostructuring, alloying, forming hierarchic structures, and using suitable binders. We hope that this review can be of benefit to more intensive investigation of Si-based anode materials.Delong Ma Zhanyi Cao Anming Hu 2014Nano-Micro Letters2014,6,4:16
2Laser-Assisted Reduction of Highly Conductive Circuits Based on Copper Nitrate for Flexible Printed Sensors显示文摘Stretchable electronic sensing devices are defining the path toward wearable electronics. High-performance flexible strain sensors attached on clothing or human skin are required for potential applications in the entertainment,health monitoring, and medical care sectors. In this work,conducting copper electrodes were fabricated onpolydimethylsiloxane as sensitive stretchable microsensors by integrating laser direct writing and transfer printing approaches. The copper electrode was reduced from copper salt using laser writing rather than the general approach of printing with pre-synthesized copper or copper oxide nanoparticles. An electrical resistivity of 96 l X cm was achieved on 40-lm-thick Cu electrodes on flexible substrates. The motion sensing functionality successfully demonstrated a high sensitivity and mechanical robustness.This in situ fabrication method leads to a path toward electronic devices on flexible substrates.Shi Bai Shigang Zhang Weiping Zhou Delong Ma Ying Ma Pooran Joshi Anming Hu 2017Nano-Micro Letters2017,9,4:10
3Kinematics of syn-tectonic unconformities and implications for the tectonic evolution of the Hala'alat Mountains at the northwestern margin of the Junggar Basin,Central Asian Orogenic Belt显示文摘The Hala'alat Mountains are located at the transition between the West Junggar and the Junggar Basin.In this area,rocks are Carboniferous,with younger strata above them that have been identified through well data and high-resolution 3D seismic profiles.Among these strata,seven unconformities are observed and distributed at the bases of:the Permian Jiamuhe Formation,the Permian Fengcheng Formation,the Triassic Baikouquan Formation,the Jurassic Badaowan Formation,the Jurassic Xishanyao Formation,the Cretaceous Tugulu Group and the Paleogene.On the basis of balanced sections,these unconformities are determined to have been formed by erosion of uplifts or rotated fault blocks primarily during the Mesozoic and Cenozoic.In conjunction with the currently understood tectonic background of the surrounding areas,the following conclusions are proposed:the unconformities at the bases of the Permian Jiamuhe and Fengcheng formations are most likely related to the subduction and closure of the Junggar Ocean during the late Carboniferous-early Permian;the unconformities at the bases of the Triassic Baikouquan and Jurassic Badaowan formations are closely related to the late Permian-Triassic Durbut sinistral slip fault;the unconformities at the bases of the middle Jurassic Xishanyao Formation and Cretaceous Tugulu Group may be related to reactivation of the Durbut dextral slip fault in the late Jurassic-early Cretaceous,and the unconformity that gives rise to the widely observed absence of the upper Cretaceous in the northern Junggar Basin may be closely related to large scale uplift.All of these geological phenomena indicate that the West Junggar was not calm in the Mesozoic and Cenozoic and that it experienced at least four periods of tectonic movement.Delong Ma Dengfa He Di Li Jieyun Tang Zheng Liu 2015Geoscience Frontiers2015,6,2:9

5Large-scale thrusting at the northern Junggar Basin since Cretaceous and its implications for the rejuvenation of the Central Asian Orogenic Belt显示文摘The Wulungu Depression is the northernmost first-order tectonic unit in the Junggar Basin.It can be divided into three sub-units:the Hongyan step-fault zone,the Suosuoquan sag and the Wulungu south slope.The Cenozoic strata in the basin are intact and Mesozoic—Cenozoic deformation can be observed in the Wulungu step-fault zone,so this is an ideal place to study the Mesozoic—Cenozoic deformation.By integration of fault-related folding theories,regional geology and drilling data,the strata of the Cretaceous—Paleogene systems are divided into small layers which are selected as the subjects of this research.The combination of the developing unconformity with existing growth strata makes it conceivable that faults on the step-fault zone have experienced different degrees of reactivation of movement since the Cretaceous.Evolutionary analyses of the small layers using 2D-Move software showed certain differences in the reactivation of different segments of the Wulungu Depression such as the timing of reactivation of thrusting,for which the reactivity time of the eastern segment was late compared with those of the western and middle segments.In addition the resurrection strength was similarly slightly different,with the shortening rate being higher in the western segment than in the other segments.Moreover,the thrust fault mechanism is basement-involved combined with triangle shear fold,for which a forward evolution model was proposed.Jieyun Tang Dengfa He Di Li Delong Ma 2015Geoscience Frontiers2015,6,2:8
6A simple way to make pre-stressed ceramics with high strength显示文摘A pre-stressing design and a simple fabrication technology to substantially improve the strength of ceramic components are presented.Residual surface compressive stress is generated in ceramic components by pressureless sintering of a green bulk coated with a thin layer of low coefficient of thermal expansion(CTE).The stress level can be controlled by changing the cross-section area ratio,Young's modulus ratio and CTE ratio of the coating.Pre-stressed ZrO_(2) ceramics coated with Al_(2)O_(3) can achieve a flexural strength of 1330±52MPa,45% higher than their uncoated counterpart.Similarly,the flexural strength of building porcelain tiles is increased by 70%,from 67±3 MPa to 114±5MPa.The damage tolerance of pre-stressed ZrO_(2) ceramics is excellent with a high residual strength of ~1200 MPa in a thermal shock test at 325℃.This simple technique can improve the mechanical performance of ceramic components with no limitation of size and shape.Yiwang Bao Fenghua Kuang Yi Sun Yueming Li Detian Wan Zongyang Shen Delong Ma Lingfeng He 2019Journal of Materiomics2019,5,4:7
7Three-dimensionally macroporous graphene-supported Fe_3O_4 composite as anode material for Li-ion batteries with long cycling life and ultrahigh rate capability显示文摘Fe3O4 is an attractive conversion reactionbased anode material with high theoretical capacity(928 mA h g-1).However,the poor cycling and rate performance hinder its applications in Li-ion batteries.In this work,we report an effective strategy to synthesize threedimensionally macroporous graphene-supported Fe3O4hybrid composite.Benefiting from advantage of the special structure,the hybrid composite exhibits excellent Li+ storage performance,delivering a high reversible capacity of980 mA h g-1at the current density of 4 A g-1even after470 cycles and ultrahigh rate capability(293 mA h g-1even at current density of 20 A g-1).Delong Ma Shuang Yuan Zhanyi Cao 2014Chinese Science Bulletin2014,59,17:6
8Epidemiological characteristics and temporal-spatial analysis of overseas imported dengue fever cases in outbreak provinces of China, 2005–2019显示文摘Background Overseas imported dengue fever is an important factor in local outbreaks of this disease in the mainland of China.To better prevent and control such local outbreaks,the epidemiological characteristics and temporal-spatial distribution of overseas imported dengue fever cases in provincial-level administrative divisions(PLADs)where dengue fever is outbreak in the mainland of China were explored.Methods Using the Chinese National Notifiable Infectious Disease Reporting Information System(CNNDS),we identified overseas imported dengue fever cases in dengue fever outbreak areas in the mainland of China from 2005 to 2019 to draw the epidemic curve and population characteristic distribution of overseas imported cases in each PLAD.Based on spatial autocorrelation analysis of ArcGIS 10.5 and temporal-spatial scanning analysis of SaTScan 9.5,we analyzed the temporal-spatial distribution of overseas imported dengue fever in dengue fever outbreak areas in the mainland of China.Results A total of 11,407 imported cases,mainly from Southeast Asia,were recorded from 2005 to 2019 in these 13 PLADs.Of which 62.1%were imported into Yunnan and Guangdong Provinces.Among the imported cases,there were more males than females,mainly from the 21–50 age group.The hot spots were concentrated in parts of Yunnan,Guangdong and Fujian Provinces.We found the cluster of infected areas were expanding northward.Conclusions Based on the analysis of overseas imported dengue cases in 13 PLADs of the mainland of China from 2005 to 2019,we obtained the epidemiological characteristics and spatial distribution of imported dengue cases.Border controls need to pay attention to key population sectors,such as 21–50 years old men and education of key populations on dengue prevention.There is a need to improve the awareness of the prevention and control of imported cases in border areas.At the same time,northern regions cannot relax their vigilance.Xinchang Lun Yiguan Wang Chunchun Zhao Haixia Wu Caiying Zhu Delong Ma Mingfang Xu Jun Wang Qiyong Liu Lei Xu Fengxia Meng 2022Infectious Diseases of Poverty2022,11,1:3
9Self-standing rationally functionalized graphene as high-performance electrode materials for supercapacitors显示文摘Supercapacitors(SCs) have attracted much attention as one of the alternative energy devices due to their high power performance,long cycle life,and low maintenance cost.Graphene is considered as an innovative and promising material due to its large theoretical specific surface area,high electrical conductivity,good mechanical properties and chemical stability.Herein,we report an effective strategy for elaborately constructing rationally functionalized self-standing graphene(SG) obtained from giant graphene oxide(GGO) paper followed by an ultrarapid thermal-processing.This treatment results in both the exfoliation of graphene sheets and the reduction of GGO by elimination of oxygencontaining groups.The as-prepared SG electrode materials without additive and conducting agent provide an excellent combination of the electrical double layer capacitor(EDLC) and pseudocapacitor(PC) functions and exhibit superior electrochemical performance,including high specific capacitance,good rate capability and excellent cycling stability when investigated in three-electrode electrochemical cells.Delong Ma Zhong Wu Zhanyi Cao 2014Journal of Energy Chemistry2014,23,3:2
