| 1 | Simultaneous mineralization of CO_2 and recovery of soluble potassium using earth-abundant potassium feldspar显示文摘CO2 capture and storage(CCS) is an important strategy in combatting anthropogenic climate change.However,commercial application of the CCS technique is currently hampered by its high energy expenditure and costs.To overcome this issue,CO2 capture and utilization(CCU) is a promising CO2 disposal method.We,for the first time,developed a promising method to mineralize CO2 using earth-abundant potassium feldspar in order to effectively reduce CO2 emissions.Our experiments demonstrate that,after adding calcium chloride hexahydrate as an additive,the K-feldspar can be transformed to Ca-silicates at 800 C,which can easily mineralize CO2 to form stable calcium carbonate and recover soluble potassium.The conversion of this process reached 84.7%.With further study,the pretreatment temperature can be reduced to 250 C using hydrothermal method by adding the solution of triethanolamine(TEA).The highest conversion can be reached 40.1%.The process of simultaneous mineralization of CO2 and recovery of soluble potassium can be easily implemented in practice and may provide an economically feasible way to tackle global anthropogenic climate change. | XIE HePing WANG YuFei JU Yang LIANG Bin ZHU JiaHua ZHANG Ru XIE LingZhi LIU Tao ZHOU XiangGe ZENG HongMei LI Chun LU HouFang | 2013 | Chinese Science Bulletin2013，58，1： | 16 |
| 2 | SIS accuracy and service performance of the BDS-3 basic system显示文摘On December 27,2018,the basic system of the third-generation BeiDou navigation satellite system(BDS-3)completed the deployment of its constellation of 18 MEO networking satellites as well as the construction of the operation control system(OCS)and began to provide basic navigation services to users worldwide.Compared with BDS-2,BDS-3 aims to offer users better navigation signals and higher precision with a series of new technologies.For example,the spaceborne atomic clock of BDS-3 is upgraded for higher performance,the Ka-band inter-satellite link is adopted for inter-satellite ranging and communication,and new B1C and B2a signals are broadcast in addition to B1I and B3I signals(compatible with BDS-2).In addition,a 9-parameter model based on a spherical harmonic function is employed for ionospheric delay corrections.Using the observation data from 18 satellites of the basic system,this paper conducts a comprehensive evaluation of the pseudorange measurement characteristics,signal-in-space(SIS)accuracy of navigation messages and global service capability of BDS-3.The results indicate that the pseudorange measurement multipath effect and observation noise of BDS-3 satellites are better than those of BDS-2;additionally,with the support of inter-satellite links,the user range error(URE)of the BDS-3 satellite broadcast ephemeris is better than 10 cm,the precision of the broadcast clock parameter is better than 1.5 ns,and the SIS accuracy is better than 0.6 m overall.Different from the traditional Klobuchar model,the BeiDou global broadcast ionospheric delay correction model(BDGIM)can provide ionospheric delay corrections better than 70%for worldwide single-frequency users.The service capability evaluation of the basic system consists mainly of the accuracy improvement of the B1I and B3I signals according to BDS-2 as well as the global positioning accuracy of the new signals.These results prove that the BDS-3 basic system has achieved the design goal;that is,both the horizontal and the vertical global positioning accuracies are better than 10 m(95%).In the future,6 MEO satellites as well as 3 GEO satellites and 3 IGSO satellites for regional enhancement purposes will be deployed for full operation;consequently,BDS-3 will definitely provide a higher SIS accuracy and better service capability. | JinPing Chen XiaoGong Hu ChengPan Tang ShanShi Zhou YuFei Yang JunYang Pan Hui Ren YueXin Ma QiuNing Tian Bin Wu Yang Yu | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，6： | 14 |

| 5 | Endovascular treatment with or without intravenous alteplase for acute ischaemic stroke due to basilar artery occlusion显示文摘Background and purpose It remains controversial if endovascular treatment(EVT)can improve the outcome of patients with acute basilar artery occlusion(BAO).This study aims to compare the functional outcomes between EVT with and without intravenous thrombolysis(IVT)first in patients who had acute ischaemic stroke(AIS)due to BAO.Methods Patients who had AIS with BAO who underwent EVT within 24 hours of onset were enrolled in this multicentre cohort study,and the efficacy and safety were compared between IVT+EVT and direct EVT.The primary outcome was 90-day functional independence.All outcomes were assessed with adjusted OR(aOR)from the multivariable logistic regression.In addition,a meta-analysis was performed on all recently published pivotal studies on functional independence after EVT in patients with BAO.Results Of 310 enrolled patients with BAO,241(78%)were treated with direct EVT and 69(22%)with IVT+EVT.Direct EVT was associated with a worse functional outcome(aOR,0.46(95%CI 0.24 to 0.85),p=0.01).IVT+EVT was associated with a lower percentage of patients who needed≥3 passes of stent retriever(10.14%vs 20.75%).The meta-analysis regression revealed a potential positive correlation between bridging with IVT first and functional independence(r=0.14(95%CI 0.05 to 0.24),p<0.01).Conclusions This study showed that compared with direct EVT,EVT with IVT first was associated with better functional outcomes in patients with BAO treated within 24 hours of onset.The meta-analysis demonstrated similar favourable efficacy of IVT first followed by EVT in patients with BAO. | Ximing Nie David Wang Yuehua Pu Yufei Wei Qixuan Lu Hongyi Yan Xin Liu Lina Zheng Jingyi Liu Xinxuan Yang Yarong Ding Dacheng Liu Wanying Duan Zhe Zhang Zhonghua Yang Miao Wen Weibin Gu Xinyi Hou Xinyi Leng Yuesong Pan Zhongrong Miao Liping Liu | 2022 | Stroke & Vascular Neurology2022，7，3： | 10 |
| 6 | Branched tetraether lipids in Chinese soils:Evaluating the fidelity of MBT/CBT proxies as paleoenvironmental proxies显示文摘The ubiquitous occurrence of branched glycerol dialkyl glycerol tetraethers(br GDGTs) in soils has allowed development of new proxies for reconstruction of past climate and environment. The methylation and cyclization degrees of br GDGTs, expressed as MBT and CBT, respectively, are reported to be mainly controlled by mean annual air temperature(MAAT) and soil p H. However, the br GDGT-derived temperatures and soil p H scatter widely when data from different environmental conditions are considered. In this study, we collected over 300 soil samples from China, which are representative of humid(Xishuangbanna, Guangzhou, and Shanghai), semi-arid(Dongying) and semi-arid/arid(Lanzhou, Tibetan Plateau) regions. Collectively we have the most extensive dataset that broadly characterizes the distribution of br GDGTs according to climate zones in China. The overall data demonstrate that the MBT/CBT derived temperatures better match the measured MAATs in humid and non-alkaline regions than those from regions of low MAP(<400 mm/yr) and above neutral soil p H(>7.0–7.5). Similarly, CBT describes soil p H much better in humid and non-alkaline soils than in semi-arid/arid and alkaline soils; the semi-arid/arid and alkaline soils tend to show a positive correlation between soil p H and CBT, which contradicts that in the humid and non-alkaline soils. While soil p H, MAAT and mean annual precipitation(MAP) are dominating factors controlling the br GDGT distribution across all climate zones, conductivity, total organic carbon and total nitrogen, as well as soil water content can also play an important role locally. Removing br GDGT-II resulted in a revised CBT index that provides more accurate estimation of p H, especially in semi-arid/arid and alkaline soils. The overall Chinese dataset demonstrates that continental air temperature derived from br GDGT-proxies can vastly deviate from real measurements and should be used with extreme caution in paleo-climate or-environment studies. | ZHENG FengFeng ZHANG ChuanLun CHEN YuFei LI FuYan MA CenLing PU Yang ZHU YuanQing WANG YongLi LIU WeiGuo | 2016 | Science China Earth Sciences2016，59，7： | 10 |
| 7 | Experimental Study on Thermal Balance of Regulated Two-Stage Turbocharged Diesel Engine at Variable Altitudes显示文摘It is significant to study thermal balance of diesel engine under different variable geometry turbocharger(VGT)vane openings at variable altitudes,which is helpful to assess the heat distribution,control the heat load and improve the heat efficiency of the diesel engine.A thermal balance test system was built to study the influence of the VGT vane opening angles on a regulated two-stage turbocharged(RTST)diesel engine’s thermal balance performance.The experiment was conducted under full load operating conditions at different altitudes(0 m,3500 m and 5500 m).Results indicated that the heat load of engine increased and the thermal efficiency decreased with the increase of altitudes under all operating conditions.As the VGT vane openings increased,the exhaust and maximum combustion temperature increased,while the maximum cylinder combustion pressure decreased.In particular,the maximum combustion temperature was more than 2000 K when the VGT vane openings were greater than 70%at the altitude of 5500 m,and the maximum combustion pressure exceeded 17 MPa when the opening of VGT vane was 70%at 0 m.The thermal efficiency of the engine decreased with the increase of VGT vane openings at the altitudes of 0 m and 5500 m,but the thermal efficiency increased and then decreased at the altitude of 3500 m.It was finally obtained that the best openings of VGT vane was 80%,60%and 50%under the engine speed of 2100 r/min at 0 m,3500 m and 5500 m,respectively. | LIU Ruilin YANG Chunhao ZHANG Zhongjie JIAO Yufei ZHOU Guangmeng | 2019 | Journal of Thermal Science2019，28，4： | 7 |

| 9 | Genome-wide identification and co-expression network analysis of the Os NF-Y gene family in rice显示文摘Nuclear factor Y(NF-Y) is a ubiquitous transcription factor that regulates important physiological and developmental processes. In this study, we identified 34 Os NF-Y genes in rice, including 6 newly identified genes. Expression profile analysis covering the whole life cycle revealed that transcripts of Os NF-Y differentially accumulated in a tissue-specific,preferential or constitutive manner. In addition, gene duplication studies and expression analyses were performed to determine the evolutionary origins of the Os NF-Y gene family.Nine Os NF-Y genes were differentially expressed after treatment of seedlings with one or more abiotic stresses such as drought, salt and cold. Analysis of expression correlation and Gene Ontology annotation suggested that Os NF-Y genes were co-expressed with genes that participated in stress, accumulation of seed storage reserves, and plant development.Co-expression analysis also revealed that Os NF-Y genes might interact with each other,suggesting that NF-Y subunits formed complexes that take part in transcriptional regulation. These results provide useful information for further elucidating the function of the NF-Y family and their regulatory pathways. | Wenjie Yang Zhanhua Lu Yufei Xiong Jialing Yao | 2017 | The Crop Journal2017，5，1： | 7 |
| 10 | Caustic study on blast-induced wing crack behaviors in dynamic–static superimposed stress field显示文摘This paper studies blast-induced wing crack behavior in a dynamic–static superimposed stress field using high-speed photography in combination with the optical method of caustics. With a static–dynamic loading setup, four PMMA plate specimens with pre-existing cracks under different static loading and the same dynamic loading were tested to observe the mechanical characteristics and the kinematic characteristics of blast-induced wing cracks during the propagation process, including crack length, crack velocity and dynamic stress intensity factor(SIF) at the crack tip. The results show that the behavior of the blast-induced wing crack is affected by the explosion stress wave and initial static stress, and the initial static stress with the direction being perpendicular to the wing crack propagation direction hinders crack propagation. Furthermore, the boundary constraint condition of the specimen plays an important role on the behavior of the crack propagation in the experiment. | Yang Liyun Yang Renshu Qu Guanglong Zhang Yufei | 2014 | International Journal of Mining Science and Technology2014，24，4： | 7 |

| 12 | A UV-B-responsive glycosyltransferase,OsUGT706C2,modulates flavonoid metabolism in rice显示文摘Although natural variations in rice flavonoids exist, and biochemical characterization of a few flavonoid glycosyltransferases has been reported, few studies focused on natural variations in tricin-lignan-glycosides and their underlying genetic basis. In this study, we carried out metabolic profiling of tricin-lignan-glycosides and identified a major quantitative gene annotated as a UDPdependent glycosyltransferase OsUGT706C2 by metabolite-based genome-wide association analysis. The putative flavonoid glycosyltransferase OsUGT706C2 was characterized as a flavonoid 7-O-glycosyltransferas in vitro and in vivo. Although the in vitro enzyme activity of OsUGT706C2 was similar to that of OsUGT706D1, the expression pattern and induced expression profile of OsUGT706C2 were very different from those of OsUGT706D1. Besides, OsUGT706C2 was specifically induced by UV-B. Constitutive expression of OsUGT706C2 in rice may modulate phenylpropanoid metabolism at both the transcript and metabolite levels. Furthermore, overexpressing OsUGT706C2 can enhance UV-B tolerance by promoting ROS scavenging in rice. Our findings might make it possible to use the glycosyltransferase OsUGT706C2 for crop improvement with respect to UVB adaptation and/or flavonoid accumulation, which may contribute to stable yield. | Feng Zhang Hao Guo Jiacheng Huang Chenkun Yang Yufei Li Xuyang Wang Lianghuan Qu Xianqing Liu Jie Luo | 2020 | Science China(Life Sciences)2020，63，7： | 5 |
| 13 | Mineralization of flue gas CO_2 with coproduction of valuable magnesium carbonate by means of magnesium chloride显示文摘CO2 mineralization and utilization is a new area for reducing the CO2 emissions.By reacting with natural mineral or industrial waste,CO2 can be transformed into valuable solid carbonate(such as calcium carbonate or magnesium carbonate)with recovery of some products simultaneously.In this paper,a novel method was proposed to mineralize CO2 by means of magnesium chloride with small energy consumption.In this method,magnesium chloride was firstly transformed into magnesium hydroxide by electrolysis.The formed magnesium hydroxide showed high reactivity to mineralize CO2.In our study,even at low concentration,CO2 can be effectively mineralized by this method,which makes it possible to directly mineralize flue gas CO2,avoiding the expensive process of CO2capture and purification.Moreover,valuable products such as hydromagnesite and nesquehonite can be recovered by this method.Because of the wide distribution of magnesium chloride in nature,large-scale CO2mineralization is potential by means of magnesium chloride. | Heping Xie Yufei Wang Wei Chu Yang Ju | 2014 | Chinese Science Bulletin2014，59，23： | 5 |
| 14 | Modeling of fast charging station equipped with energy storage显示文摘The popularization of EVs(electric vehicles) has brought an increasingly heavy burden to the development of charging facilities. To meet the demand of rapid energy supply during the driving period, it is necessary to establish a fast charging station in public area. However, EVs arrive at the charging station randomly and connect to the distribution network for fast charging, it causes the grid power to fluctuate greatly and the peak-valley loads to alternate frequently, which is harmful to the stability of distribution network. In order to reduce the power fluctuation of random charging, the energy storage is used for fast charging stations. The queuing model is determined to demonstrate the load characteristics of fast charging station, and the state space of fast charging station system is described by Markov chain. After that the power of grid and energy storage is quantified as the number of charging pile, and each type of power is configured rationally to establish the random charging model of energy storage fast charging station. Finally, the economic benefit is analyzed according to the queuing theory to verify the feasibility of the model. | Yu Zhang Yang He Xudong Wang Yufei Wang Chen Fang Hua Xue Chaoming Fang | 2018 | Global Energy Interconnection2018，1，2： | 5 |
| 15 | 1-Naphthol induced PtsAg nanocorals as bifunctional cathode and anode catalysts of direct formic acid fuel cells显示文摘Developing highly efficient bifunctional cathode and anode electrocatalysts is very important for the large-scale application of direct formic acid fuel cells. However, the high-cost and poor CO-tolera nee ability of the most commonly used Pt greatly block this process. To in crease the utilizatio n efficie ncy and exte nd bifunctional properties of precious Pt, herei n, coral-like Pt3Ag nano crystals are developed as an excelle nt bifunctional electrocatalyst through a facile one-pot solvothermal method. The formation mechanism of Ptgg nanocorals has been elaborated well via a series of control experiments. It is proved that 1-naphthol serving as a guiding surfactant plays a key role in the formation of high-quality nano corals. Thanks to the unique coral-like structure and alloy effects, the developed Ptgg nano corals present sign ificantly enhanced electrocatalytic properties (including activity, stability and CO-toleranee ability) towards both the cathodic oxygen reduction and anodic formic acid oxidati on, as compared with those of commercial Pt black and Pt-based nan oparticles. The prese nt synthetic method can also be extended to fabricate other bimetallic electrocatalysts with unique morphology and structure. | Xian Jiang Yang Liu Jiaxin Wang Yufei Wang Yuexin Xiong Qun Liu Naixu Li Jiancheng Zhou Gengtao Fu Dongmei Sun Yawen Tang | 2019 | Nano Research2019，12，2： | 4 |
| 16 | V_r:A new index to represent the variation rate of geomagnetic activity显示文摘By calculating the hourly standard deviation of the first-order differences of the horizontal geomagnetic component minute data,a new index Vr to represent the variation rate of the geomagnetic field was introduced.Vr-indices show similar trends in the temporal change at different observatories and have simultaneous peak values at the observatories covering a large span geographically,which reveals that the source of geomagnetic disturbances represented by Vr is in the magnetosphere.Based on the comparison among Vr,Kp and ap,it is found that generally Vr changes linearly with Kp and ap,which means that the rapid changes of magnetic field usually exist together with magnetic disturbances.But there are exceptions.As Vr can be easily produced by individual observatory in quasi real time and is more sensitive to the variation rate of geomagnetic field rather than the field itself,it can be expected to serve for monitoring or predicting the geomagnetic-induced event in a quick and intuitive way. | Dongmei Yang Yufei He Chuanhua Chen Jiadong Qian | 2010 | Earthquake Science2010，23，4： | 4 |

| 18 | Inhibition of M-MuLV reverse transcriptase activity by fullerene derivatives显示文摘Influence of fullerene (C60) derivatives on M-MuLV reverse transcriptase activity is investi- gated. Two water-soluble fullerene derivatives, fullerol (C60(OH)23-24) and trimalonic acid C60 (TMA C60, C63(COOH)6) are used in the experiments and their effects on in vitro reverse transcription-polymerase chain reaction (RT-PCR) of β-actin mRNA in HeLa cells are determined. PCR products are detected by agarose gel electrophoresis. It is found that the amounts of PCR products decrease with addition of either of two fullerene derivatives to RT reaction mixture. The inhibition of fullerene derivatives is dose-dependent, and IC50 values of fullerol and TMA C60 are 0.089 and 0.039 mmol/L, respectively. The amount of PCR products obtained by direct addition of fullerol or TMA C60 to PCR are greater than those obtained by addition of the equivalent amount of fullerol or TMA C60 to RT, indicating an inhibitory ef- fect of fullerol or TMA C60 on RT. The compensative experiment of M-MuLV reverse transcriptase shows that increasing enzyme amounts can antagonize the activity of fullerol or TMA C60. These results imply that fullerenes can inhibit M-MuLV reverse transcriptase activity, with the inhibition of TMA C60 slightly stronger than fullerol, and that their potential in treatment of diseases induced by RNA viruses such as leukemia virus needs further investigation. | MENG Xianmei CHEN Zhe LI Bo ZHANG Yufei ZHAO Dongxu YANG Xinlin | 2006 | Chinese Science Bulletin2006，51，20： | 4 |
| 19 | On-chip chalcogenide microresonators with low-threshold parametric oscillation显示文摘Chalcogenide glass (ChG) is an attractive material for highly efficient nonlinear photonics,which can cover an ultrabroadband wavelength window from the near-visible to the footprint infrared region. However,it remains a challenge to implement highly-efficient and low-threshold optical parametric processes in chip-scale ChG devices due to thermal and light-induced instabilities as well as a high-loss factor in ChG films. Here,we develop a systematic fabrication process for high-performance photonic-chip-integrated ChG devices,by which planarintegrated ChG microresonators with an intrinsic quality (Q) factor above 1 million are demonstrated. In particular,an in situ light-induced annealing method is introduced to overcome the longstanding instability underlying ChG film. In high-Q ChG microresonators,optical parametric oscillations with threshold power as low as 5.4 mW are demonstrated for the first time,to our best knowledge. Our results would contribute to efforts of making efficient and low-threshold optical microcombs not only in the near-infrared as presented but more promisingly in the midinfrared range. | BIN ZHANG PINGYANG ZENG ZELIN YANG DI XIA JIAXIN ZHAO YAODONG SUN YUFEI HUANG JINGCUI SONG JINGSHUN PAN HUANJIE CHENG DUKYONG CHOI ZHAOHUI LI | 2021 | Photonics Research2021，9，7： | 4 |
| 20 | Rice metabolic regulatory network spanning the entire life cycle显示文摘As one of the most important crops in the world,rice(Oryza sativa)is a model plant for metabolome research.Although many studies have focused on the analysis of specific tissues,the changes in metab-olite abundance across the entire life cycle have not yet been determined.In this study,combining both tar-geted and nontargeted metabolite profiling methods,a total of 825 annotated metabolites were quantified in rice samples from different tissues covering the entire life cycle.The contents of metabolites in different tissues of rice were significantly different,with various metabolites accumulating in the plumule and radicle during seed germination.Combining these data with transcriptome data obtained from the same time period,we constructed the Rice Metabolic Regulation Network.The metabolites and co-expressed genes were further divided into 12 clusters according to their accumulation patterns,with members within each cluster displaying a uniform and clear pattern of abundance across development.Using this dataset,we established a comprehensive metabolic profile of the rice life cycle and used two independent strategies to identify novel transcription factors-namely the use of known regulatory genes as bait to screen for new networks underlying lignin metabolism and the unbiased identification of new glycerophospholipid metabolism regulators on the basis of tissue specificity.This study thus demonstrates how guilt-by-association analysis of metabolome and transcriptome data spanning the entire life cycle in cereal crops provides novel resources and tools to aid in understanding the mechanisms underlying important agro-nomic traits. | Chenkun Yang Shuangqian Shen Shen Zhou Yufei Li Yuyuan Mao Junjie Zhou Yuheng Shi Longxu An Qianqian Zhou Wenju Peng Yuanyuan Lyu Xuemei Liu Wei Chen Shouchuang Wang Lianghuan Qu Xianqing Liu Alisdair R.Fernie Jie Luo | 2022 | Molecular Plant2022，15，2： | 3 |
