1Multispherical interactions and their effects on the Tibetan Plateau's earth system: a review of the recent researches显示文摘The Tibetan Plateau(TP) is a regional Earth system showing very strong interactions among its lithosphere, hydrosphere, cryosphere, biosphere, atmosphere, and anthrosphere. hese interactions manifest TP's impact on surrounding regions and relect TP's response to the global change. Quantifying the multispherical interactions is critically important to understand the TP environment. Our recent years researches including the ongoing program entitled ‘Tibetan Multi-Spheres Interactions and heir Resource-Environment Signiicance(TIMI)', the completed program entitled. ‘Paleo-Altitudes of Tibetan Plateau and Environment(PATE)', as well as the other relating projects have focused on multidisciplinary research approaches and emphasized on three major pathways: Eurasia-Indian plates collision on deep-Earth dynamics, uplit impact on Earth's mantle–crust dynamics, and contemporary interface on land surface and atmospheric dynamics. Our researches have taken in situ measurement as priority and developed several platforms of data acquisition and analysis, including the platforms of water-phase transformations, and ecosystem observations. Our ield investigations have been conducted to obtain data about stratum, paleontology, paleoenvironment, genetic diferentiation of animals and plants. We have developed conceptual and mathematical models for crust uplit formation, paleoclimate, glacial melt,water–air interface lux, vegetation climate, and soil erosion. We have also assessed the anthropogenic impacts on environment. Our researches have achieved new and reliable redating of the mantle–crust interaction and initial formation of the TP, found the interaction between tectonics and uplit of the TP and resultant paleoaltitude acting as a spreading source; discovered the interaction between the westerlies and Indian monsoon acting as a control chain that dominates the TP's contemporary environment. he scientiic results can play fundamental roles in supporting the TP's resource exploration and societal sustainable development.Tandong Yao Fuyuan Wu Lin Ding Jimin Sun Liping Zhu Shilong Piao Tao Deng Xijun Ni Hongbo Zheng Hua Ouyang 2015National Science Review2015,2,4:35
2Stepwise advance of the Mu Us Desert since late Pliocene:Evidence from a red clay-loess record显示文摘Analyses of paleomagnetic polarity reversals, magnetic susceptibility and grain size on the red clay-loess sequence, about 280 m thick, at Jingbian show that this sequence contains most of the stratigraphic units recorded in the standard red clay-loess sections of the Loess Plateau over the past 3.5 Ma. Using sand particle percentage ( > 63 μm%) of the eolian sequence as a proxy indicator of desert extent and aridity in the dust source regions, it is found that during the past 3.5 Ma, there are three important climatic events indicating the advance of the Mu Us Desert. The events occurred at about 2.6, 1.1 and 0.6 MaBP, respectively. The stepwise advance of the Mu Us Desert may be linked closely to increase in global ice volume and uplift of the Tibetan Plateau in the late Cenozoic.Zhongli Ding Jimin Sun Dongsheng Liu 1999Chinese Science Bulletin1999,44,13:12
3Pedogenic carbonate isotope record of vegetational evolution since late Miocene in Loess Plateau显示文摘lsotopic analyses for paleovegetational evolution have been carried out on samples of the pedogenic carbonate nodules in the Red Clay-Loess sequence at Lingtai (35°N), the Loess Plateau. Stable carbon isotopic composition indicates that ( ⅰ ) C4 plants might be present at least by7.0 Ma; ( ⅱ ) C4 plants expanded gradually between ~4.0 and ~3.2 Ma, and their biomass fraction was up to 50%; and ( ⅲ ) the biomass of C4 vegetation since ~2.0 Ma seems to have been decreased to the level (about 20%) before 4.0 Ma. C4 plant expansion at Lingtai cannot be fully understood with the 'global C4 expansion' model because it occurred much later up to 3.0 Ma than in Pakistan, which indicates that some changes in the regional climatic system may also contribute to C3/C4 shift except changes in atmospheric CO2 concentrations and temperature. The latitudinal zone for C3/C4 transition seems to move southwards slightly in East Asia, compared with the case in North America where 37°N is the idealShiling Yang Zhongli Ding Zhaoyan Gu Jimin Sun Shangfa Xiong 1999Chinese Science Bulletin1999,44,11:6
4Chronology of environmental events over East Asia during the past 130 ka显示文摘In the transitional region between the Loess Plateau and deserts, 4 sections located respectively at Yuling, Hengshan, Dingbian and Huining of China are studied. The high-resolution paleoclimatic records obtained show that environmental events on varying time scales have happened over East Asia. These events are dated with the time scales established using the recently-developed approach of Automatic Orbital Tuning. This leads to the establishment of the chronology of the environmental events.Zhongli Ding Jimin Sun Zhiwei Yu Dongsheng Liu 1998Chinese Science Bulletin1998,43,21:6
5High-resolution anisotropy of magnetic susceptibility record in the central Chinese Loess Plateau and its paleoenvironment implications显示文摘We analyze high-resolution anisotropy of magnetic susceptibility (AMS) of the loess-paleosol successions at Luochuan, central Chinese Loess Plateau, in order to investigate the AMS characteristics and their climatic implications. Our results indicate a normal sedimentary magnetic fabric for almost of all samples, characterized by minimum susceptibility axes grouped in an almost vertical direction. Magnetic foliation and anisotropy degree show upwards decreasing trend due to decreasing post-depositional compaction. Magnetic lineations show no preferred directions and thus cannot indicate paleowind patterns. AMS parameters at Luochuan are controlled by particle size, pedogenesis, and sedimentary compaction. The high peaks of magnetic foliation and anisotropy degree of L2, L3, L6, L9, and L15 correspond to the coarse particle sizes of these loess beds, indicating the grain-size dependence of AMS.LIU WeiMing SUN JiMin 2012Science China Earth Sciences2012,55,3:5

8Medical Additive Manufacturing: From a Frontier Technology to the Research and Development of Products显示文摘1.Research and development(R&D)and the challenges of raw materials for medical additive manufacturing Raw materials for medical additive manufacturing have a wide range of commonalities that are also seen in many other fields,making them an important basis in the field of three-dimensional(3D)printing.Problems and challenges related to material types,powder properties,formability,viscoelasticity,and so forth also share common features.For example,many metal materials are used in the field of aviation,while metals,polymers,and inorganic materials are used in the field of biomedicine.The most widely used materials in biomedicine are biocompatible.Various homogeneous and non-homogeneous composites are also available for 3D printing,and impose an additional challenge in additive manufacturing;the use of heterogeneous composites in 3D printing is particularly challenging.Guixing Qiu Wenjiang Ding Wei Tian Ling Qin Yu Zhao Lianmeng Zhang Jian Lu Daijie Chen Guangyi Yuan Chengtie Wu Bingheng Lu Ruxu Du Jimin Chen Mo Elbestawi Zhongwei Gu Dichen Li Wei Sun Yuanjin Zhao Jie He Dadi Jin Bin Liu Kai Zhang Jianmo Li Kam WLeong Dewei Zhao Dingjun Hao Yingfang Ao Xuliang Deng Huilin Yang ShaoKeh Hsu Yingqi Chen Long Li Jianping Fan Guohui Nie Yun Chen Hui Zeng Wei Chen Yuxiao Lai 2020Engineering2020,6,11:1
