1Fault Systems and Their Mechanisms of the Formation and Distribution of the Tarim Basin,NW China显示文摘This article aims to analyze the main controlling factors of development,distribution and evolution of the fault systems in the Tarim Basin.Based on the seismic profile interpretation,comprehensive analysis of the drilling and geologic data,six fault systems maybe recognized in the Tarim Basin,they are the foreland fault system of the South Tianshan Mountain,the northern Tarim uplift fault system,North Tarim depression fault system,central fault system,Southwest Tarim fault system,and Southeast Tarim fault system.It is indicated that the main differences exist at the development,evolution and distribution of the fault systems in the Tarim Basin.The sub-fault systems can be recognized according to the differences of the fault development and distribution in the interior of the fault system.It is characterized that the multi-level differential development and distribution of the fault systems exist in the Tarim Basin.The fault belt developed in the Paleozoic strata mainly distribute at the paleo-uplift and paleo-slope in the interior of the Tarim Basin,and the fault belt occurred in the Meso–Cenozoic beds mainly develop at the peripheral foreland depressions.Zonal and segment differential development and distribution of the fault systems also exist in the Tarim Basin.The formation and distribution of the Tarim fault systems is of complex controlling mechanisms.Poly-phase structural movement and tectonic transition controls the multi-phase differential development and distribution of the fault systems in the Tarim Basin.Multi-level differential development and distribution is controlled by multi-level detachment belt and regional unconformities.Zonal and segment differential development and distribution of the Tarim fault systems maybe controlled by pre-existed basement structural texture.The major direction of the fault systems in the Tarim Basin is controlled by the later stage basin-mountain coupling.Liangjie Tang Taizhu Huang Haijun Qiu Guimei Wan Meng Li Yong Yang Daqing Xie Gang Chen 2014Journal of Earth Science2014,25,1:6
2Appropriately adapted properties of hot-extruded Zn-0.5Cu-xFe alloys aimed for biodegradable guided bone regeneration membrane application显示文摘Appropriately adapted comprehensive mechanical properties,degradation behavior and biocompatibility are prerequisites for the application of Zn-based biodegradable implants.In this study,hot-extruded Zn-0.5Cu-xFe(x=0.1,0.2 and 0.4 wt%)alloys were fabricated as candidates for biodegradable materials for guided bone regeneration(GBR)membranes.The hot-extrusion process and Cu alloying were expected mostly to enhance the mechanical properties,and the Fe alloying was added mainly for regulating the degradation.The microstructure,mechanical properties and in vitro degradation behavior were systematically investigated.The ZnCuFe alloys were composed of a Zn matrix and FeZn13 phase.With increasing Fe content,a higher FeZn13 phase precipitation with larger particles was observed.Since elongation declined significantly until fracture with increasing Fe content up to 0.4 wt%,the ZnCuFe(0.2 wt%)alloy achieved a good balance between mechanical strength and ductility,with an ultimate tensile strength of 202.3 MPa and elongation at fracture of 41.2%.Moreover,the addition of Fe successfully accelerated the degradation of ZnCuFe alloys.The ZnCuFe(0.2 wt%)alloy showed relatively uniform corrosion in the long-term degradation test.Furthermore,extracts of the ZnCuFe(0.2 wt%)alloy showed no apparent cytotoxic effects against L929 fibroblasts,Saos-2 osteoblasts or TAg periosteal cells.The ZnCuFe(0.2 wt%)alloy exhibited the potential to inhibit bacterial adhesion of Streptococcus gordonii and mixed oral bacteria.Our study provides evidence that the ZnCuFe(0.2 wt%)alloy can represent a promising material for the application as a suitable GBR membrane.Wentai Zhang Ping Li Gang Shen Xiaoshan Mo Chao Zhou Dorothea Alexander Frank Rupp Jürgen Geis-Gerstorfer Haijun Zhang Guojiang Wan 2021Bioactive Materials2021,6,4:6
3Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes显示文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients.Peinan Chen Xueke Zhao Fuyou Zhou Xin Song Shoujia Hu Yan Jin Xianzeng Wang Xuena Han ZongminFan Ran Wang Bei Li Wenli Han Panpan Wang Jilin Li Lixin Wan Liguo Zhang Qide Bao Fubao Chang Yanru Qin Zhiwei Chang Jianwei Ku Haijun Yang Ling Yuan Jingli Ren Xuemin Li Lidong Wang 2020Cancer Biology & Medicine2020,17,1:6

5Anisotropy-Related Machining Characteristics in Ultra-Precision Diamond Cutting of Crystalline Copper显示文摘Deformation behavior at grain levels greatly affects the machining characteristics of crystalline materials.In the present work,we investigate the influence of material anisotropy on ultra-precision diamond cutting of single crystalline and polycrystalline copper by experiments and crystal plasticity finite element simulations.Specifically,diamond turning and in situ SEM orthogonal cutting experiments are carried out to provide direct experimental evidence of the material anisotropy-dependent cutting results in terms of machined surface morphology and chip profile.Corresponding numerical simulations with the analysis of built stress further validate experimental results and reveal the mechanisms governing the material anisotropy influence.The above findings provide insight into the fabrication of ultra-smooth surfaces of polycrystalline metals by ultraprecision diamond turning.Zhanfeng Wan Junjie Zhang Guo Li Zongwei Xu Haijun Zhang Jianguo Zhang Alexander Hartmaier Fengzhou Fang Yongda Yan Tao Sun 2020Nanomanufacturing and Metrology2020,3,2:2
6Electric field controlled superlubricity of fullerene-based host–guest assembly显示文摘Controlling friction by the electric field is a promising way to improve the tribological performance of a variety of movable mechanical systems.In this work,the assembly structure and microscale superlubricity of a host–guest assembly are effectively controlled by the electric field.With the help of the scanning tunneling microscopy(STM)technique,the host–guest assembly structures constructed by the co-assembly of fullerene derivative(Fluorene-C60)with macrocycles(4B2A and 3B2A)are explicitly characterized.Combined with density functional theory(DFT),the distinct different assembly behaviors of fullerene derivatives are revealed at different probe biases,which is attributed to the molecular polarity of the fullerene derivative.Through the control on the adsorption behavior,the friction coefficient of host–guest assembly is demonstrated to be controllable in the electric field by using atomic force microscopy(AFM).At positive probe bias,the friction coefficient of the host–guest assembly is significantly reduced and achieves superlubricity(μmin=0.0049).The efforts not only help us gain insight into the host–guest assembly mechanism controlled by the electric field,but also promote the further application of fullerene in micro-electro-mechanical systems(MEMS).Shanchao Tan Hongyu Shi Xin Du Kunpeng Wang Haijun Xu Junhua Wan Ke Deng Qingdao Zeng Yuhong Liu 2023Nano Research2023,16,1:1

14A Nitride-Reinforced NbMoTaWHfN Refractory High-Entropy Alloy with Potential Ultra-High-Temperature Engineering Applications显示文摘Refractory high-entropy alloys(RHEAs)have promising applications as the new generation of hightemperature alloys in hypersonic vehicles,aero-engines,gas turbines,and nuclear power plants.This study focuses on the microstructures and mechanical properties of the NbMoTaW(HfN)_(x)(x=0,0.3,0.7,and 1.0)RHEAs.The alloys consist of multiple phases of body-centered cubic(BCC),hafnium nitride(HfN),or multicomponent nitride(MN)phases.As the x contents increase,the grain size becomes smaller,and the strength gradually increases.The compressive yield strengths of the NbMoTaWHfN RHEA at ambient temperature,1000,1400,and 1800℃ were found to be 1682,1192,792,and 288 MPa,respectively.The high-temperature strength of this alloy is an inspiring result that exceeds the high temperature and strength of most known alloys,including high-entropy alloys,refractory metals,and superalloys.The HfN phase has a significant effect on strengthening due to its high structural stability and sluggish grain coarsening,even at ultra-high temperatures.Its superior properties endow the NbMoTaWHfN RHEA with potential for a wide range of engineering applications at ultra-high temperatures.This work offers a strategy for the design of high-temperature alloys and proposes an ultra-high-temperature alloy with potential for future engineering applications.Yixing Wan Yanhai Cheng Yongxiong Chen Zhibin Zhang Yanan Liu Haijun Gong Baolong Shen Xiubing Liang 2023Engineering2023,,11:0
