1An Important Spreading Event of the Neo-Tethys Ocean during the Late Jurassic and Early Cretaceous: Evidence from Zircon U-Pb SHRIMP Dating on Diabase in Nagarze, Southern Tibet显示文摘Widely distributed in Gyangze-Chigu area, southern Tibet, NW- and nearly E-W-trending diabase(gabbro)-gabbro diorite dykes are regarded as the product of the large-scale spreading of the late Neo-Tethys Ocean. In order to constrain the emplacement age of these dykes, zircons of two samples from diabases in Nagarze were dated by using the U-Pb SHRIMP method. Two nearly the same weighted mean 206Pb/238U ages were obtained in this paper, which are 134.9±1.8 Ma (MSWD= 0.65) and 135.5±2.1 Ma (MSWD=1.40), respectively. They not only represent the crystallization age of the diabase, but also documented an important spreading event of the Neo-Tethys Ocean during the late Jurassic and early Cretaceous. This dating result is of great significance to reconstruct the temporal framework of the late Neo-Tethys Ocean in the Qinghai-Tibet Plateau.JIANG Sihong NIE Fengjun HU Peng LIU Yan 2006Acta Geologica Sinica(English Edition)2006,80,4:28
2Evolution of regional transport dominance in China 1910-2012显示文摘Transport infrastructure plays an important role in shaping the configuration of spatial socio-economic structures and influencing regional accessibility. Although China's transport infrastructure has been experiencing a rapid development in the last 100 years, there lacks a systematic examination of the complete evolution history of China's transport development, particularly with all kinds of transport modes. This paper first aims to clarify the history of China's transportation from 1910 to 2012, and divides its evolution process into five periods(1911, 1935, 1953, 1981 and 2012) whereby each period represents the preliminary development time for each transport mode. Second, the paper calculates the transport dominance and analyses its spatial distribution in each period, with county as the basic analysis unit. Transport dominance here is defined as an integrated indicator for evaluating regional transport conditions. The results demonstrate the following:(1) areas with relative good transport dominance have expanded from scattered dots such as Tianjin, Shanghai, Guangzhou in 1911 to extensive areas with each provincial city as cores in 2012;(2) transport development is improved by advances in transportation technology. The construction of modern transport infrastructures such as seaports, airports, high-speed rails(HSRs), and freeways lead the expansion of national territorial areas with good and excellent transport dominance and the increase of the value of transport dominance over time;(3) transport dominance is spatially unevenly distributed and exhibits resemblance with the expansion of transport network, which is closely related to China's socio-economic development and policies.HU Hao WANG Jiaoe JIN Fengjun DING Nan 2015Journal of Geographical Sciences2015,25,6:12
3Enhancing sensitivity of microbial fuel cell sensors for low concentration biodegradable organic matter detection:Regulation of substrate concentration,anode area and external resistance显示文摘The relatively low sensitivity is an important reason for restricting the microbial fuel cell(MFC)sensors'application in low concentration biodegradable organic matter(BOM)detection.The startup parameters,including substrate concentration,anode area and external resistance,were regulated to enhance the sensitivity of MFC sensors.The results demonstrated that both the substrate concentration and anode area were positively correlated with the sensitivity of MFC sensors,and an external resistance of 210Ωwas found to be optimal in terms of sensitivity of MFC sensors.Optimized MFC sensors had lower detection limit(1 mg/L)and higher sensitivity(Slope value of the linear regression curve was 1.02),which effectively overcome the limitation of low concentration BOM detection.The essential reason is that optimized MFC sensors had higher coulombic efficiency,which was beneficial to improve the sensitivity of MFC sensors.The main impact of the substrate concentration and anode area was to regulate the proportion between electrogens and nonelectrogens,biomass and living cells of the anode biofilm.The external resistance mainly affected the morphology structure and the proportion of living cells of the anode.This study demonstrated an effective way to improve the sensitivity of MFC sensors for low concentration BOM detection.Yangyang Gao Sha Wang Fengjun Yin Pin Hu Xingzu Wang Yuan Liu Hong Liu 2021Journal of Environmental Sciences2021,33,3:2
4Neuro-regenerative imidazole-functionalized GelMA hydrogel loaded with hAMSC and SDF-1α promote stem cell differentiation and repair focal brain injury显示文摘Brain tissues that are severely damaged by traumatic brain injury(TBI)is hardly regenerated,which leads to a cavity or a repair with glial scarring.Stem-cell therapy is one viable option to treat TBI-caused brain tissue damage,whose use is,whereas,limited by the low survival rate and differentiation efficiency of stem cells.To approach this problem,we developed an injectable hydrogel using imidazole groups-modified gelatin methacrylate(GelMA-imid).In addition,polydopamine(PDA)nanoparticles were used as carrier for stromal-cell derived factor-1(SDF-1α).GelMA-imid hydrogel loaded with PDA@SDF-1αnanoparticles and human amniotic mesenchymal stromal cells(hAMSCs)were injected into the damaged area in an in-vivo cryogenic injury model in rats.The hydrogel had low module and its average pore size was 204.61±41.41 nm,which were suitable for the migration,proliferation and differentiation of stem cells.In-vitro cell scratch and differentiation assays showed that the imidazole groups and SDF-1αcould promote the migration of hAMSCs to injury site and their differentiation into nerve cells.The highest amount of nissl body was detected in the group of GelMA-imid/SDF-1α/hAMSCs hydrogel in the in-vivo model.Additionally,histological analysis showed that GelMA-imid/SDF-1α/hAMSCs hydrogel could facilitate the regeneration of regenerate endogenous nerve cells.In summary,the GelMA-imid/SDF-1α/hAMSCs hydrogel promoted homing and differentiation of hAMSCs into nerve cells,and showed great application potential for the physiological recovery of TBI.Yantao Zheng Gang Wu Limei Chen Ying Zhang Yuwei Luo Yong Zheng Fengjun Hu Tymor Forouzanfar Haiyan Lin Bin Liu 2021Bioactive Materials2021,6,3:2
5SPACEBORNE SAR REAL-TIME ECHO SIMULATION PLATFORM BASED ON VPX显示文摘To perform the ground test of a spaceborne Synthetic Aperture Radar(SAR) system, an echo simulator with the characteristics of multimode, multi-assemblage, and real time is proposed in this paper. A hardware platform of the real-time echo simulator based on the VPX bus is designed. With this platform, real-time multi-point echo generation and scenario targets echo generation can be achieved by the real-time signal processing in Field Programmable Gate Array(FPGA), utilizing the parameters calculated by the industry computers. Furthermore, this platform can output different signals if it is expanded to multi-channels, making it possible for the assignment of echo generation and test in different spaceborne SAR modes. The test results with the actual SAR system show that this platform can satisfy the system requirements and is now used in practice.Ni Chao Hu Xiao Zhang Zhimin Zhao Fengjun 2014Journal of Electronics(China)2014,31,3:2
