1Transmutation of ancient settlements and environmental changes between 6000-2000 aBP in the Chaohu Lake Basin, East China显示文摘Based on the temporal-spatial distribution features of ancient settlement sites from the middle and late Neolithic Age to the Han dynasty in the Chaohu Lake Basin of Anhui Province,East China,using the methods of GIS combined with the reconstructed paleoenvironment by the records of lake sediment since Holocene,the transmutation of ancient settlements with response to environmental changes in this area has been discussed.Studies show that the main feature of transmutation of ancient settlements from the middle and late Neolithic Age to the Han Dynasty was that the distribution of settlements in this area changed from high altitudes to low ones and kept approaching the Chaohu Lake with the passage of time.These could be the response to the climate change from warm-moist to a relatively warm-dry condition during the middle Holocene,leading to the lake level fluctuations.The large area of exposed land provided enough space for human activities.These indicate that the above changes in geomorphologic evolution and hydrology influenced by climate conditions affected the transmutation of ancient settlements greatly.The distribution pattern of settlement sites was that the number of sites in the west was more than in the east.This pattern may be related to the geomorphologic conditions such as frequent channel shifting of the Yangtze River as well as flood disasters during the Holocene optimum.Therefore,climate change was the inducement of the transmutation of ancient settlements in the Chaohu Lake Basin,which exerted great influence on the distribution,expansion and development of the ancient settlements.WU Li WANG Xinyuan ZHOU Kunshu MO Duowen ZHU Cheng GAO Chao ZHANG Guangsheng LI Lan LIU Li HAN Weiguang 2010Journal of Geographical Sciences2010,20,5:16
2Environmental changes during early-middle Holocene from the sediment record of the Chaohu Lake,Anhui Province显示文摘A typical lake sediment core is obtained from the Chaohu Lake in the lower reaches of the Yangtze River,Anhui Province,China.The timing scale is constrained by AMS 14 C dating method.Climate proxies such as pollen and grain size in the core are analyzed to reconstruct the environment changes at this site approximately between 9870 and 2170 cal.a BP.The results indicate that at the research area, the climate in the early-middle Holocene had evolved through 3 stages.From 9870 to 6040 cal.a BP, proxy records show a warm and dry climate with low water levels after the late-glacial period.During this stage,cool and dry events occurred at about 8910 and 6060-6030 cal.a BP.Then,between 6040 and 4860 cal.a BP,the climate was humid and vegetation was more flourishing in the Chaohu Lake Valley.The Holocene Optimum occurred at 5840-5500 cal.a BP in the Chaohu Lake,showing the best condition of water and heat.Elm Decline occurred at the period of 5380-4930 cal.a BP.Since 4860 cal.a BP,the climate was warm and dry through 2170 cal.a BP as shown in both pollen spectrum and grain-size histories.Two obvious dry events occurred in 3760 and 2170 cal.a BP,respectively.At 2170 cal.a BP,the water level of the Chaohu Lake reached the lowest as the lakebed possibly exposed. Such lake sediment observations are consistent with the historical records in this area.XinYuan Wang GuangSheng Zhang Li Wu XiHui Zhang EnLou Zhang XiaYun Xiao QingFeng Jiang 2008Chinese Science Bulletin2008,53,S1:15
3Superhydrophobic coatings for corrosion protection of magnesium alloys显示文摘Magnesium(Mg)alloys show great potential to be extensively applied in practice owing to their superior properties,while the poor corrosion resistance does undoubtedly restrict their applications.Superhydrophobic coatings with good repellency to corrosive solutions can significantly decrease the interaction between the corrosive species and the substrate,so that they are receiving a lot of attention to improve the corrosion resistance of Mg alloys.Various strategies have been introduced to develop a superhydrophobic coating on Mg alloys,which were reviewed to elucidate the current research status to provide a clue or thinking for beginning researchers.Further,the existing issues of superhydrophobic coating were discussed,especially for their real applications in practice,mainly owing to their poor mechanical stability.Based on the existing issues,the future study was discussed to improve the stability of hierarchical structures and entrapped air pockets,impart the superhydrophobic coating self-healing property to repair the damaged area during service,provide double protection by incorporation of corrosion inhibitors,or even introduce slippery liquid-infused porous surfaces with lubricant layer to provide better corrosion protection for Mg alloys.Wenhui Yao Liang Wu Guangsheng Huang Bin Jiang Andrej Atrens Fusheng Pan 2020Journal of Materials Science & Technology2020,52,17:15
4Clarifying the roles of grain boundary and grain orientation on the corrosion and discharge processes of α-Mg based Mg-Li alloys for primary Mg-air batteries显示文摘The corrosion behavior at open circuit potential(OCP)and discharge properties under applied anodic currents of twoα-Mg based Mg-Li alloys,i.e.,LAZ131 and LAZ531,with different microstructural features for primary Mg-air batteries are investigated.The results show that the grain boundaries contribute equally to the corrosion and discharge processes,which are attacked preferentially than the grain interiors and accelerate the dissolution processes ofα-Mg based Mg-Li alloys.The(10-10)/(11-20)orientated grains are attacked preferentially than the(0002)orientated grains on the corrosion and discharge process.The increased corrosion rate and improved discharge properties are attributed to the refinement of grain size,decreased content of(0002)orientated grains and increased content of(10-10)/(11-20)orientated grains.Of those,the LAZ531 alloy possesses high and steady discharge voltage at small discharge current density for long time,with the values of 1.4801 V at 2.5 mA cm^(-2)and 1.3742 V at 10 mA cm^(-2).Huabao Yang Liang Wu Bin Jiang Wenjun Liu Jiangfeng Song Guangsheng Huang Dingfei Zhang Fusheng Pan 2021Journal of Materials Science & Technology2021,,3:9
5Effects of Fe concentration on microstructure and corrosion of Mg-6Al-1Zn-xFe alloys for fracturing balls applications显示文摘Mg-6A1-1 Zn-xFe (x = 0,1,3,5 and 7 wt%) alloys were prepared by powder metallurgy and followed by hot extrusion. Majority of Fe element exists as insoluble particles in the alloys. The as-extruded alloys showed higher degradable rates but less stable mechanical properties than as-annealed alloys. Corrosion rate of all the alloys increased with increasing Fe concentration, reaching 2.4 mL cm^-2 h^-1.0.2% yield strength of all the alloys was higher than 150 MPa. In short, Mg-6A1-1 Zn-xFe alloys have an attractive combination of corrosion and mechanical properties, which holds a bright future for fracturing balls applications.Cheng Zhang Liang Wu Guangsheng Huang Lin Chen Dabiao Xia Bin Jiang Andrej Atrens Fusheng Pan 2019Journal of Materials Science & Technology2019,35,9:5
6Dramatic transition between electric and magnetic rotations in ^(106)Ag显示文摘The lifetimes for the states of magnetic dipole band in106Ag have been measured using the Doppler-shift attenuation method via the reaction of100Mo(11B,5n)106Ag at a beam energy of 60 MeV.The reduced transition strengths of the magnetic dipole band,the B(M1)/B(E2)ratios together with the signature of the level energy as a function of angular momentum for the positive parity states of106Ag show that a drastic change of excitation mode,that is,from electric rotation to magnetic rotation,occurs within one unit of spin at around Iπ=12+.Theoretical calculations based on the triaxial projected shell model consistently reproduce the experimental data and provide an explanation on the nature of observed phenomena such that the dynamical drift of the rotational axis suddenly from the principal axis to the tilted one,along the positive parity bands of106Ag.ZHENG Yun ZHU LiHua CHEN YongShou WU XiaoGuang HE ChuangYe HAO Xin LIU Ying WANG ZhiMin LI XueQin LI GuangSheng GAO ZaoChun SUN HuiBin 2014Science China(Physics,Mechanics & Astronomy)2014,57,9:4
7Influence of substrate temperature on growth of a-Si:H films by reactive facing target sputtering deposition显示文摘Hydrogenated amorphous silicon(a-Si:H) films were deposited by reactive facing target sputtering(FTS) technique with a mixture of Ar and H2 reaction gas.Fourier transform infrared(FTIR) absorption,Raman scattering and ultraviolet-visible optical absorption are used to investigate the microstructure and optical properties of the deposited films.The decrease of the concentration of bonded hydrogen,especially that of(Si-H2)n with increasing substrate temperature(Ts),was observed in FTIR spectra,suggesting the atomic density increases and the concentration of microvoids decrease in a-Si:H films.The increase of both the short range order and the intermediate range order of amorphous network for a-Si:H films were verified by Raman scattering spectra,in which increasing Ts decreasing the band width of TO and the scattering intensity ratio ITA/ITO were obtained.All above results clarify the effect of increasing Ts on the microstructure amelioration for a-Si:H films.The reduction of disordered domains is correlated with the film growing process,where the increased surface diffusion mobility and etching of weak bonds is induced by increasing Ts.Furthermore,analysis of optical absorption indicates that the films with a lower optical band gap and a narrower band edge can be obtained by this FTS technique.YU Wei,MENG LingHai,YUAN Jing,LU HaiJiang,WU ShuJie & FU GuangSheng College of Physics Science and Technology,Hebei University,Baoding 071002,China 2010Science China(Physics,Mechanics & Astronomy)2010,53,5:3

9Single-shot AAV-vectored vaccine against SARS-CoV-2 with fast and long-lasting immunity显示文摘Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines,the epidemic prevention and control are still challenging.Here,we employ a capsid and antigen structure engineering(CASE)strategy to manufacture an adenoassociated viral serotype 6-based vaccine(S663V-RBD),which expresses trimeric receptor binding domain(RBD)of spike protein fused with a biological adjuvant RS09.Impressively,the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months.Compared to the licensed BBIBP-CorV(Sinopharm,China),a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type,C.37(Lambda)and B.1.617.2(Delta).More interestingly,the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid.Given its effectiveness,the CASE-based S663VRBD may provide a new solution for the current and next pandemic.Fuhua Wu Shuang Luo Yongshun Zhang Yangsen Ou Hairui Wang Zhaofei Guo Chunting He Shuting Bai Penghui He Min Jiang Xiaoyan Chen Guangsheng Du Xun Sun 2023Acta Pharmaceutica Sinica B2023,13,5:2
102021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://links.lww.com7CM9/A978).Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun 2022Chinese Medical Journal2022,,8:2
11Effects of ferrites on magnetic transport properties in La_(2/3)Sr_(1/3)MnO_3/ferrites composites显示文摘Effects of soft-magnetic MnZn ferrite (Mn0.5Zn0.5Fe2O4, MZF) and hard-magnetic Ba ferrite (BaO·6Fe2O3, BaM) on the structure and magnetic transport properties of [La2/3Sr1/3MnO3] (LSMO)/(x) [ferrites] (ferrites=MZF, BaM) composites have been investigated. It was found that the inclusion of MZF phase reduces magnetization and ferromagnetic-paramagnetic transition temperature (Tc) of the composites. With increasing the content of the dopants, the high-temperature magnetoresistance (MR) decreases, whereas low-temperature MR increases and reaches 42% at 150 K and x=0.1. However, for the LSMO/BaM composites, magnetization and ferromagnetic- paramagnetic transition temperature (Tc) decrease firstly as x<5%, and then increase as x>5%. The resistivity of the composites increases by five orders of magnitude at x=1% and is out of measured range at x=5%. High magnetic field has little effect on the resistivity and magnetoresistance for the composites with x>5%, which may originate from the pinning effect of BaM grains.Zhengyou ZHOU Xiaoshan WU Jun DU Sheng XU Xiaojun BAI Guangsheng LUO Fengyi JIANG 2009Acta Metallurgica Sinica(English Letters)2009,22,1:1

17Parallelized microfluidic droplet generators with improved ladder-tree distributors for production of monodisperseγ-Al_(2)O_(3)microspheres显示文摘In this paper,we present a parallelized microfluidic device with improved ladder-tree distributors for the scaled-up production of monodisperse microspheres.Owing to the improved distribution form comprising a ladder distributor in the center and tree distributors around the circumference,the uniformity of the generated droplets for our device was improved by 32.9%and 86.1%compared to those achieved in devices with conventional tree and ladder distributors,respectively,in the final production stage with 32 droplet generators,indicating the potential of our device for further scale-up while maintaining the monodispersity of the generated droplets.The effect of the 2D scale-up of our device was investigated by varying the continuous-phase flow rate and viscosity.Using our device,γ-Al_(2)O_(3)microspheres with a diameter of 598.1μm and a CV of 2.58%,as catalyst support for microreactors,were continuously synthesized at high production rate.The nickel-based catalyst prepared fromγ-Al_(2)O_(3)microspheres with large specific surface area and pore volume had an average NiO size of 14 nm,which was 60.9%of that supported on industrial support.The CO methanation conversion of the Ni@Al_(2)O_(3)microspheres was 1.7 times larger than Ni@Al_(2)O_(3)industrial support at 140℃.Huilin Yi Shuliang Lu Jiajia Wu Yujun Wang Guangsheng Luo 2022Particuology2022,20,3:1

19Relationship between breakthrough curve and adsorption isotherm of Ca(Ⅱ)imprinted chitosan microspheres for metal adsorption显示文摘In this work,an equilibrium-dispersion model was successfully established to describe the breakthrough performance of Ca(II) imprinted chitosan(Ca(II)-CS) microspheres packed column for metal adsorption,and the assumptions of Langmuir isotherms and axial dispersion controlled mass transfer process were confirmed.The axial dispersion coefficient in Ca(II)-CS microspheres packed column was found to be almost proportional to the linear velocity and fit for prediction through single breakthrough test.Sensitivity analysis for breakthrough curve indicated the axial dispersion coefficient as well as Langmuir coefficient was sensitive variable for deep removal requirement.The retrieval of the adsorption isotherms of Ca(II)-CS microspheres from breakthrough curve was fulfilled by modelling calibration.A strategy based on the correlation between adsorption isotherms and breakthrough performance was further proposed to simplify the column adsorption design using absorbents with small/uniform size and fast adsorption kinetics like Ca(II)-CS microspheres to cut down the gap between lab and industry.Yangcheng Lu Jing He Longwen Wu Guangsheng Luo 2016Chinese Journal of Chemical Engineering2016,24,2:1
