1New eolian red clay sequence on the western Chinese Loess Plateau linked to onset of Asian desertification about 25 Ma ago显示文摘The expansion of inland Asia deserts has considerably influenced the environmental, social and economic activities in Asia. Aridification of inland Asia, especially timing of the initiation of Asian desertification, is a contentious topic in paleoclimatology. Late Cenozoic eolian loess-red clay sequences on the Chinese Loess Plateau, which possess abundant paleoclimatic and paleo-environmental information, can be regarded as an indicator of inland Asia desertification. Here we present a detailed magnetostratigraphic investigation of a new red clay sequence about 654 m in Zhuanglang located at the western Chinese Loess Plateau. Sedimentological, geochemical, mineralogical, and quartz morphological lines of evidence show that the red clay is of eolian origin. Magnetostratigraphic correlations indicate that this core sequence spans from 25.6 to 4.8 Ma, and typical eolian red clay appears as early as 25 Ma. This extends the lower limit of the red clay on the Chinese Loess Plateau from the previously thought early Miocene back into the late Oligocene. This new red clay record further implies that the inland Asia desertification was initiated at least by the late Oligocene. This sequence provides a unique high-resolution geological record for understanding the inland Asia desertification process since the late Oligocene.QIANG XiaoKe AN ZhiSheng SONG YouGui CHANG Hong SUN YouBin LIU WeiGuo AO Hong DONG JiBao FU ChaoFeng WU Feng LU FengYan CAI YanJun ZHOU WeiJian CAO JunJi XU XinWen AI Li 2011Science China Earth Sciences2011,54,1:73
2Adsorption of heavy metal ions from aqueous solution by carboxylated cellulose nanocrystals显示文摘A novel nanoadsorbent for the removal of heavy metal ions is reported.Cotton was first hydrolyzed to obtain cellulose nanocrystals(CNCs).CNCs were then chemically modified with succinic anhydride to obtain SCNCs.The sodic nanoadsorbent(NaSCNCs) was further prepared by treatment of SCNCs with saturated NaHCO 3 aqueous solution.Batch experiments were carried out with SCNCs and NaSCNCs for the removal of Pb 2+ and Cd 2+.The effects of contact time,pH,initial adsorption concentration,coexisting ions and the regeneration performance were investigated.Kinetic studies showed that the adsorption equilibrium time of Pb 2+ and Cd 2+ was reached within 150 min on SCNCs and 5 min on NaSCNCs.The adsorption capacities of Pb 2+ and Cd 2+ on SCNCs and NaSCNCs increased with increasing pH.The adsorption isotherm was well fitted by the Langmuir model.The maximum adsorption capacities of SCNCs and NaSCNCs for Pb 2+ and Cd 2+ were 367.6 mg/g,259.7 mg/g and 465.1 mg/g,344.8 mg/g,respectively.SCNCs and NaSCNCs showed high selectivity and interference resistance from coexisting ions for the adsorption of Pb 2+.NaSCNCs could be efficiently regenerated with a mild saturated NaCl solution with no loss of capacity after two recycles.The adsorption mechanisms of SCNCs and NaSCNCs were discussed.Xiaolin Yu Shengrui Tong Maofa Ge Lingyan Wu Junchao Zuo Changyan Cao Weiguo Song 2013Journal of Environmental Sciences2013,25,5:29
3Carbon isotopic composition of modern soil and paleosol as a response to vegetation change on the Chinese Loess Plateau显示文摘The relationship between the carbon isotopic composition of paleosols and paleovegetation on the Loess Plateau is still unclear. One of the main reasons is that we are short of knowledge about the characteristics of the carbon isotopic composition of modern soil in this area. A preliminary investigation of the carbon isotopic compositions of the modern soil and the loess/paleosol sequence on the Loess Plateau shows that the carbon isotopic composition of modern soil is consistent with the distribution of modern plants on the Loess Plateau, where the ecosystem is dominated by a mixture of C4 and C3 plants. Comparing theδ13C values of modern soil and loess-paleosol sequences from the Xunyi profile, we conclude that C3 plants dominated the landscape during loess sediment stages, while C4 plants expanded during paleosol stages.LIU Weiguo NING Youfeng AN Zhisheng WU Zhenghai LU Huayu CAO Yunning 2005Science China Earth Sciences2005,48,1:24

6Longitudinal non-vascular transport pathways originating from acupuncture points in extremities visualised in human body显示文摘A subcutaneous transport pathway in humans has been previously visualised by injection of a paramagnetic tracer into the specific region of skin.In the current study,we further investigated the behaviours of imaging tracers in the transport pathways using imaging techniques.Three types of imaging tracers,including Gd-DTPA,iodised oil,and fluorescein sodium,were hypodermically injected into different acupuncture points of healthy volunteers to visualise the transport pathways by magnetic resonance imaging(MRI),X-ray,CT,and a digital fluorescein camera.Several longitudinal transport pathways in the arms and feet,which represent venous vessels and subcutaneous transport pathways(STPs) without well-defined boundaries,were visualised by MRI.Among the visualised veins,the partial walls of a few veins were enhanced by Gd-DTPA.The fluorescent images further indicated that STPs likely represent boundless pathways.The findings in this study suggested that specific anatomical structures within the subcutaneous tissues or the partial walls of certain veins werenot vascular conduits but rather represented unique transport pathways in humans that warrant extensive future studies.Hongyi Li Jiabin Tong Weiguo Cao Min Chen Hua Li Hong Dai Liang Xu Xiaoliang Chen 2014Chinese Science Bulletin2014,59,35:10
7Carbonaceous aerogel and CoNiAl-LDH@CA nanocomposites derived from biomass for high performance pseudo-supercapacitor显示文摘Conversion of waste biomass to valuable carbonaceous material is a sustainable and environmental benign method for energy and reduction of greenhouse gas emission. Herein, a two-step hydrothermal method was developed to fabricate high performance electrode material from pomelo peels. In the first step, the pomelo peels were transformed to carbonaceous aerogel(CA), which constructed of threedimensional, sponge-like brown monolith with hierarchical pores, low-density(0.032 g/cm^3) and excellent mechanical flexibility. Then, the cobalt nickel aluminum layered double hydroxide(CoNiAl-LDH) was in situ loaded on the surface of CA to form exquisite core-shell structure(CoNiAl-LDH@CA) through the second hydrothermal step. When used as an electrode material for supercapacitor, CoNiAl-LDH@CA exhibited high specific capacitances of 1,134 F/g at 1 A/g and 902 F/g at 10 A/g, respectively.Furthermore, they displayed an excellent cycling stability without an obvious capacitance decrease after 4,000 cycles.Sidi Zhang Jian Liu Peipei Huang Hao Wang Changyan Cao Weiguo Song 2017Science Bulletin2017,62,12:5

11Study on the Performance of PECVD Silicon Nitride Thin Films显示文摘Mechanical properties and corrosion resistance of Si3N4 films are studied by using different experiment parameters, such as plasma enhanced chemical vapor deposition(PECVD) RF power, ratio of reaction gas, reaction pressure and working temperature. The etching process of Si3N4 is studied by inductively coupled plasma (ICP) with a gas mixture of SF6 and O2. The influence of the technique parameters, such as ICP power, DC bias, gas composition, total flow rate, on the etching selectivity of Si3N4/EPG533 which is used as a mask layer and the etching rate of Si3N4 is studied, in order to get a better etching selectivity of Si3N4/EPG533 with a faster etching rate of Si3N4. The optimized process parameters of etching Si3N4 by ICP are obtained after a series of experiments and analysis. Under the conditions of total ICP power of 250 W, DC bias of 50W, total flow rate of 40 sccm and O2 composition of 30%, the etching selectivity of 2.05 can be reached when Si3N4 etching rate is 336 nm/min.LIU Liang LIU Weiguo CAO Na CAI Changlong 2013Defence Technology(防务技术)2013,9,2:3
12Uniform single atomic Cu_(1)-C_(4)sites anchored in graphdiyne for hydroxylation of benzene to phenol显示文摘For single-atom catalysts(SACs),the catalyst supports are not only anchors for single atoms,but also modulators for geometric and electronic structures,which determine their catalytic performance.Selecting an appropriate support to prepare SACs with uniform coordination environments is critical for achieving optimal performance and clarifying the relationship between the structure and the property of SACs.Approaching such a goal is still a significant challenge.Taking advantage of the strong d-πinteraction between Cu atoms and diacetylenic in a graphdiyne(GDY)support,we present an efficient and simple strategy for fabricating Cu single atoms anchored on GDY(Cu_(1)/GDY)with uniform Cu_(1)-C_(4)single sites under mild conditions.The Cu atomic structure was confirmed by combining synchrotron radiation X-ray absorption spectroscopy,X-ray photoele ctron spectroscopy and density functional theory(DFT)calculations.The as-prepared Cu1/GDY exhibits much higher activity than state-of-the-art SACs in direct benzene oxidation to phenol with H_(2)O_(2)reaction,with turnover frequency values of 251 h^(-1)at room temperature and 1889 h^(-1)at 60℃,respectively.Furthermore,even with a high benzene conversion of86%,high phenol sele ctivity(96%)is maintaine d,which can be ascribed to the hydrophobic and oleophyllic surface nature of Cu1/GDY for benzene adsorption and phenol desorption.Both experiments and DFT calculations indicate that Cu_(1)-C_(4)single sites are more effective at activating H_(2)O_(2)to form Cu=O bonds,which are important active intermediates for benzene oxidation to phenol.Jia Yu Changyan Cao Hongqiang Jin Weiming Chen Qikai Shen Peipei Li Lirong Zheng Feng He Weiguo Song Yuliang Li 2022National Science Review2022,9,9:3

14Gaussian-curvature-derived invariants for isometry显示文摘Surface deformations without tearing or stretching, preserving the intrinsic properties, are called isometries. This paper presents a new definition of Gaussian curvature moments (GCMs) by the integral of n power of Gaussian curvature. Then a series of moment invariants, called Gaussian curvature moment invariants (GCMIs), are derived via GCMs. These moment invariants share many good properties under rigid transformations and isometric non-rigid transformations, and Gaussian-Bonnet theorem is a special case of GCMI. GCMIs are invariant under isometry and scaling transformations. We construct an invariant vector as a descriptor for a surface via GCMIs, and a modified χ2 distance is defined as a measure of similarity. Finally, experiments show that it is a reliable descriptor for isometric non-rigid shape.CAO WeiGuo HU Ping LIU YuJie GONG Ming LI Hua 2013Science China(Information Sciences)2013,56,9:2
15Early Miocene Paleoaltitude of the Tuotuohe Basin,Central-Northern Tibetan Plateau and its Tectonic Implications显示文摘Reconstruction of the paleoaltitude history of the Tibetan Plateau is critical for understanding the linkage between tectonics and its effect on regional and global climate change.Presently,most of the paleoaltitude studies are concentrated on the southern and southeastern part of the Tibetan Plateau,and few studies have been conducted in the central-northern part.In this paper we focused on the Wudaoliang Formation in the Tuotuohe Basin,central to northern Tibetan Plateau,to reconstruct paleoaltitude based on carbonate oxygen isotopes.The carbonate samples are primary or have experienced an early stage of digenesis.Based on the thermodynamic and empirical model results,the paleoaltitude of the Wudaoliang Formation is found to be around 2700–3260 m(average of 2980±280 m)in the early Miocene(~24 Ma).Integrating paleoaltitude results from Wudaoliang Basin and our results,we conclude that crustal shortening and tectonic activity were strong during the late Eocene to late Oligocene-early Miocene and relatively weak during the early Miocene in the central-northern Tibetan Plateau.LI Leyi CHANG Hong GUAN Chong LIU Weiguo CAO Yunning 2020Acta Geologica Sinica(English Edition)2020,94,5:2

17Self-powered electronic paper with energy supplies and information inputs solely from mechanical motions显示文摘The electronic paper(E-paper)displays features such as flexibility,sunlight visibility,and low power consumption,which makes it ideal for Internet of Things(IoT)applications where the goal is to eliminate bulky power modules.Here,we report a unique self-powered E-paper(SPEP),where information inputs and energy supplies are all converted from mechanical motion by a triboelectric nanogenerator(TENG).The operation of an electrophoretic E-paper is first investigated,identifying the current density as a determinative parameter for driving pigment particle motion and color change.Electrical and optical responses of the E-paper driven by a slidingmode TENG are then found to be consistent with that under a current source mode.All-in-one monochromic and chromatic SPEPs integrated with a flexible transparent TENG are finally demonstrated,and a pixelated SPEP is discussed for future research.The sliding-driven mechanism of SPEP allows for a potential handwriting function,is free of an extra power supply,and promises undoubtedly a wide range of future applications.YIFAN GU TINGTING HOU PENG CHEN JINXIN CAO CHONGXIANG PAN WEIGUO HU BO-RU YANG XIONG PU AND ZHONG LIN WANG 2020Photonics Research2020,8,9:2
18Grazing impact of microzooplankton on phytoplankton in the Xiamen Bay using pigment-specific dilution technique显示文摘Phytoplankton group-specific growth and microzooplankton grazing were determined seasonally using the dilution technique with high-performance liquid chromatography (HPLC) in the Xiamen Bay,a subtropical bay in southeast China,between May 2003 and February 2004. The results showed that growth rates of phytoplankton ranged from 0.71 to 2.2 d-1 with the highest value occurred in the inner bay in May. Microzooplankton grazing rates ranged from 0.5 to 3.1 d-1 with the highest value occurred in the inner bay in August. Microzooplankton grazing impact ranged from 39% to 95% on total phytoplankton Chl a biomass,and 65% to 181% on primary production. The growth and grazing rates of each phytoplankton group varied,the highest growth rate (up to 3.3 d-1) was recorded for diatoms in August,while the maximum grazing rate (up to 2.1 d-1) was recorded for chlorophytes in February in the inner bay. Among main phytoplankton groups,grazing pressure of microzooplankton ranged from 10% to 83% on Chl a biomass,and from 14% to 151% on primary production. The highest grazing pressure on biomass was observed for cryptophytes (83%) in August,while the maximum grazing pressure on primary production was observed for cyanobacteria (up to 151%) in December in the inner bay. Net growth rates of larger phytoplanktons (diatoms and dinoflagellates) were higher than those of smaller groups (prasinophytes,chlorophytes and cyanobacteria). Relative preference index showed that microzooplankton grazed preferentially on prasinophytes and avoided to harvest diatoms in cold seasons (December and February).HUANG Bangqin LIU Yuan XIANG Weiguo TIAN Haojie LIU Hongbin CAO Zhenrui HONG Huasheng 2008Acta Oceanologica Sinica2008,27,5:2
19Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant.Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu 2023Science China(Life Sciences)2023,66,5:2
20Direct synthesis of ordered mesoporous ZSM-5 zeolites from in situ crystallization of carbonaceous SBA-15显示文摘Two types of ordered mesoporous ZSM-5 zeolites with different mesopores were synthesized by a two-step method. First,carbonaceous SBA-15 was produced by in situ carbonization of SBA-15/P123 composite. Then the obtained SBA-15/C composite was transformed into crystallized mesoporous ZSM-5 by impregnation TPAOH followed by steam-assisted crystallization. The final calcined samples synthesized with typical SBA-15/P123 precursor showed a wormlike morphology with the mean mesopore size of 4.6 nm, while samples synthesized with the addition of trimethylbenzene as swelling agent in the precursor exhibited the morphology of microsphere with the mesopore size of about 9.5 nm. Both two types of mesoporous ZSM-5 zeolites exhibited large surface area and mesopore structure. The steam-assisted crystallization(SAC) was performed with lower consumption of solvents. This two-step method may also be suitable for synthesizing other ordered mesoporous zeolites used as catalysts in some catalytic processes.Fangfang Wei Qiuyun Zhang Hong Wu Changyan Cao Weiguo Song 2017Science China Chemistry2017,60,12:1
