| 1 | Mesoproterozoic age for Xiamaling Formation in North China Plate indicated by zircon SHRIMP dating显示文摘Zircon grains of magmatic origin from tuffite layers in the Xiamaling Formation at Zhaojiashan Village, Xuanhua area, Hebei Province, were used for zircon dating with a Sensitive High-Resolution Ion Microprobe (SHRIMP II), which gives a weighted mean 207Pb/206Pb age of 1366±9 Ma. It shows a very similar age (1368±12 Ma) as the zircon dating from the Xiamaling Formation in Western Hill, Beijing. This age proposes that the Xiamaling Formation in the North China plate should be of Mesoproterozoic, instead of Neoproterozoic based on K-Ar, Ar-Ar dating. The new zircon age also indicates the devel- opment of macrofossils algae from the Mesoproterozoic age. | GAO LinZhi ZHANG ChuanHeng SHI XiaoYing SONG Biao WANG ZiQiang LIU YaoMing | 2008 | Chinese Science Bulletin2008,53,17: | 68 |
| 2 | Seismic Sequence in Carbonate Rocks By Vibrational Liquefaction显示文摘On the basis of the records of strong seismic events taking place in soft carbonate sediments, a new seismic sequence system of vibrational liquefaction is established, which consists of a series of units, such as escaped structure of micrite veins and liquefied deformation formed in the period of seismic liquefaction, land subsidence structure after liquefaction, tsunamic hummocky and turbidite produced by seismic events, This sequence is a generalization and summation of field observation in vast areas, which shows the whole process of a strong seismic event and provides an unified theoretical explanation. The pattern of the seismic sequence by vibrational liquefaction provides one of correlation standards for geologists in the field to discriminate events in carbonate sequences. Based on the pattern of seismic sequence, the authors first advance a new conception of the Palaeo-Tanlu (Tancheng-Lujiang) Zone and discuss primarily its geological significations. | Qiao Xiufu, Song Tianrui, Gao Linzhi, Peng Yang, Li Haibing, Gao Mai, Song Biao and Zhang QiaodaInstitute of Geology, Chinese Academy of Geological Sciences, Beijing | 1994 | Acta Geologica Sinica(English Edition)1994,68,3: | 39 |
| 3 | Zircon U-Pb dating for the earliest Neoproterozoic mafic magmatism in the southern margin of the North China Block显示文摘Huge diabase occurs within the Pro- terozoic strata in the southern margin of the North China Block, geographically in the northern parts of Anhui and Jiangsu provinces, where no strata younger than Neoproterozoic have been found. Zir- cons from the diabase show three different structures from cathodoluminesecence imaging, but they are all of magmatic origin. SHRIMP U-Pb dating yields a range of 206Pb/238U ages from 2600 to 124 Ma, but two geological events can clearly be identified from both concordant and discordant ages. One gives two weighted mean 207Pb/206Pb ages of 976 ± 24 and 1038 ± 26 Ma which are interpreted as timing of dia- base crystallization, and the other has a weighted mean 207Pb/206Pb age of 2523 ± 52 Ma that repre- sents formation time of inherited zircon from the old crust. The dating results indicate that the mafic magmatic event occurred in a transition period from the latest Mesoproterozoic to the earliest Neopro- terozoic, consistent with global subduction of Grenvill ocean crust to result in the assembly of superconti- nent Rodinia. Therefore, the North China Block needs to be taken into account when reconstructing the position of China continents within the framework of Rodinia supercontinent. | LIU Yongqing GAO Linzhi LIU Yanxue SONG Biao WANG Zongxiu | 2006 | Chinese Science Bulletin2006,51,19: | 36 |
| 4 | Reclassification of the Meso- and Neoproterozoic Chronostratigraphy of North China by SHRIMP Zircon Ages显示文摘High-quality zircon U-Pb ages acquired from Meso- and Neoproterozoic strata in North China in recent years has provided a high-resolution chronostratigraphic framework for dating. A basis of this high-level chronostratigraphic system provides the foundation for a global Precambrian study and stratigraphic correlation and so recent geological studies have focused attention on systemic SHRIMP zircon dating. A chronology of Meso- and Neoproterozoic strata and the time of origin of the overlying Changcheng System is given on the basis of new SHRIMP zircon dating from the Qianxi Complex and diabase of the Chuanlinggou Formation. A new tectonostratigraphy for a Neoproterozoic chronostratigraphic framework in the southeastern margin of the North China continent is underpinned by the new SHRIMP zircon dating of a Neoproterozoic mafic magma diabase in the Jiao-Liao-Xu-Huai Sub-Province. | GAO Linzhi ZHANG Chuanheng LIU Pengju TANG Feng SONG Biao DING Xiaozhong | 2009 | Acta Geologica Sinica(English Edition)2009,83,6: | 36 |
| 5 | Effect of postoperative early enteral nutrition on clinical outcomes and immune function of cholangiocarcinoma patients with malignant obstructive jaundice显示文摘BACKGROUND Most cholangiocarcinoma patients with malignant obstructive jaundice(MOJ)have varying degrees of malnutrition and immunodeficiency preoperatively.Therefore,perioperative nutritional support has important clinical significance in the treatment of cholangiocarcinoma.AIM To investigate the effects of postoperative early enteral nutrition(EEN)on immunity function and clinical outcomes of cholangiocarcinoma patients with MOJ.METHODS This prospective clinical study included 60 cholangiocarcinoma patients with MOJ who underwent surgery.The patients were randomly divided into an experimental group and a control group according to the nutrition support modes.The control group received postoperative total parenteral nutrition(TPN),whereas the experimental group received postoperative EEN and parenteral nutrition(PN;EEN+PN).The clinical outcomes,postoperative immune function,incidences of surgical site infection and bile leakage,intestinal function recovery time,average hospitalization days,and hospitalization expenses of the two groups were assessed on postoperative days(PODs)1,3,and 7.RESULTS The CD3+T,CD4+T,CD8+T,and CD4+T/CD8+T cell count and the immunoglobulin(Ig)G,IgM,and IgA levels in the EEN+PN group were significantly higher than those in the TPN group on PODs 3 and 7(P<0.05),whereas no significant differences in the CD3+T,CD4+T,CD8+T,and CD4+T/CD8+T cell counts and IgG,IgM,and IgA levels before operation and on POD 1 were found between the two groups(P>0.05).The intestinal function recovery time and postoperative hospital stay were shorter(P<0.001 for both)in the EEN+PN group than in the TPN group.The hospitalization expenses of the EEN+PN group were lower than those of the TPN group(P<0.001).However,the incidence of abdominal distension was higher than in the EEN+PN group than in the TPN group(P<0.05).The incidence rates of biliary leakage and surgical site infection were not significantly different between the two groups(P>0.05).CONCLUSION A postoperative EEN program could reduce the incidence of postoperative complications and improve the clinical outcomes and immune functions of cholangiocarcinoma patients with MOJ and is thus beneficial to patient recovery. | Bing-Qiang Ma Shi-Yong Chen Ze-Bin Jiang Biao Wu Yu He Xin-Xin Wang Yuan Li Peng Gao Xiao-Jun Yang | 2020 | World Journal of Gastroenterology2020,26,46: | 14 |

| 7 | Efficacy of noninvasive evaluations in monitoring inflammatory bowel disease activity: a prospective study in China显示文摘AIM To optimize the efficacy of noninvasive evaluations in monitoring the endoscopic activity of inflammatory bowel disease(IBD).METHODS Fecal calprotectin(FC), clinical activity index(CDAI or CAI), C-reactive protein(CRP), erythrocyte sedimentation rate(ESR), and procalcitonin(PCT) were measured for 136 IBD patients. Also, FC was measured in 25 irritable bowel syndrome(IBS) patients that served as controls. Then, endoscopic activity was determined by other two endoscopists for colonic or ileo-colonic Crohn's disease(CICD) with the 'simple endoscopic score for Crohn's disease'(SES-CD), CDrelated surgery patients with the Rutgeerts score, and ulcerative colitis(UC) with the Mayo score. The efficacies of these evaluations to predict the endoscopic disease activity were assessed by Mann-Whitney test, χ~2 test, Spearman's correlation, and multiple linear regression analysis.RESULTS The median FC levels in CD, UC, and IBS patients were 449.6(IQR, 137.9-1344.8), 497.9(IQR, 131.7-118.0), and 9.9(IQR, 0-49.7) μg/g, respectively(P < 0.001). For FC, CDAI or CAI, CRP, and ESR differed significantly between endoscopic active and remission in CICD and UC patients, but not in CD-related surgery patients. The SES-CD correlated closely with levels of FC(r = 0.802), followed by CDAI(r = 0.734), CRP(r = 0.658), and ESR(r = 0.557). The Mayo score also correlated significantly with FC(r = 0.837), CAI(r = 0.776), ESR(r = 0.644), and CRP(r = 0.634). For FC, a cut-off value of 250 μg/g indicated endoscopic active inflammation with accuracies of 87.5%, 60%, and 91.1%, respectively, for CICD, CD-related surgery, and UC patients. Moreover, clinical FC activity(CFA) calculated as 0.8 × FC + 4.6 × CDAI showed higher area under the curve(AUC) of 0.962 for CICD and CFA calculated as 0.2 × FC + 50 × CAI showed higher AUC(0.980) for UC patients than the FC. Also, the diagnostic accuracy of FC in identifying patients with mucosal inflammation in clinical remission was reflected by an AUC of 0.91 for CICD and 0.96 for UC patients. CONCLUSION FC is the most promising noninvasive evaluation for monitoring the endoscopic activity of CICD and UC. CFA might be more accurate for IBD activity evaluation. | Jin-Min Chen Tao Liu Shan Gao Xu-Dong Tong Fei-Hong Deng Biao Nie | 2017 | World Journal of Gastroenterology2017,23,46: | 9 |
| 8 | Graphene-encapsulated blackberry-like porous silicon nanospheres prepared by modest magnesiothermic reduction for high-performance lithium-ion battery anode显示文摘Porous silicon(Si)nanostructures have aroused much interest as lithium-ion battery anodes because of the large space to accommodate the volume change in lithiation and delithiation and shorter ion transfer distance.However,fabrication of porous structures tends to be difficult to control and complex,so,the final electrochemical performance can be compromised.Herein,a modest magnesiothermic reduction(MMR)reaction is demonstrated to produce blackberry-like porous Si nanospheres(PSSs)controllably using magnesium silicide(Mg_(2)Si)as Mg source and SiO_(2)nanospheres as the reactant.This improved MR method provides good control of the kinetics and heat release compared to the traditional MR(TMR)method using Mg powder as the reactant.The PSSs obtained by MMR reaction has higher structural integrity than that fabricated by TMR.After encapsulation with reduced graphene oxide,the Si/C composite exhibits superior cycling stability and rates such as a high reversible capacity of 1034 mAh·g^(-1)at0.5 C(4200 mAh·g^(-1)at 1.0 C)after 1000 cycles,capacity retention of 79.5%,and high rate capacity of 497 mAh·g^(-1)at 2.0 C.This strategy offers a new route to fabricate highperformance porous Si anodes and can be extended to other materials such as germanium. | Ben Xiang Wei-Li An Ji-Jiang Fu Shi-Xiong Mei Si-Guang Guo Xu-Ming Zhang Biao Gao Paul K.Chu | 2021 | Rare Metals2021,40,2: | 9 |

| 13 | Lithiophilic N-doped carbon bowls induced Li deposition in layered graphene film for advanced lithium metal batteries显示文摘Lithium(Li)metal with high theoretical capacity and low electrochemical potential is the most ideal anode for next-generation high-energy batteries.However,the practical implementation of Li anode has been hindered by dendritic growth and volume expansion during cycling,which results in low Coulombic efficiency(CE),short lifespan,and safety hazards.Here,we report a highly stable and dendrite-free Li metal anode by utilizing N-doped hollow porous bowl-like hard carbon/reduced graphene nanosheets(CB@rGO)hybrids as three-dimensional(3D)conductive and lithiophilic scaffold host.The lithiophilic carbon bowl(CB)mainly works as excellent guides during the Li plating process,whereas the rGO layer with high conductivity and mechanical stability maintains the integrity of the composite by confining the volume change in long-range order during cycling.Moreover,the local current density can be reduced due to the 3D conductive framework.Therefore,CB@rGO presents a low lithium metal nucleation overpotential of 18 mV,high CE of 98%,and stable cycling without obvious voltage fluctuation for over 600 cycles at a current density of 1 mA cm^(-2).Our study not only provides a good CB@rGO host and pre-Lithiated CB@rGO composite anode electrode,but also brings a new strategy of designing 3D electrodes for those active materials suffering from severe volume expansion. | Xiaoyu Feng Hong-Hui Wu Biao Gao Michai Swietostawski Xin He Qiaobao Zhang | 2022 | Nano Research2022,15,1: | 6 |

| 15 | Exchange-coupling interaction and effective anisotropy in nanocomposite permanent materials显示文摘Taking Nd2Fe14B/α-Fe as example, the exchange-coupling interactions between magnetically soft and hard grains in nanocomposite permanent materials and their effects on the effective anisotropy of materials were investigated. The calculation results expressed that the exchange-coupling interactions are enhanced with the reduction of grain size, and the effective anisotropy of materials decreases with the reduction of gram size and the increase of magnetically soft phase component. The remanence and the effective anisotropy of materials possess the opposite variation trend with the change of grain size and phase ratio. The mean grain size should be in the range of 10-15 nm and the ratio of soft phase should be less than 50% for getting the magnet with high energy product. | Ruwei Gao Weicun Feng Wei Chen Biao Wang Guangbing Han Peng Zhang | 2002 | Chinese Science Bulletin2002,47,14: | 5 |
| 16 | CoFe-LDH nanowire arrays on graphite felt: A high-performance oxygen evolution electrocatalyst in alkaline media显示文摘Developing non-noble-metal oxygen evolution reaction(OER) electrocatalysts with high performance is critical to electrocatalytic water splitting. In this work, we fabricated Co Fe-layered double hydroxide(LDH) nanowire arrays on graphite felt(Co Fe-LDH/GF) via a hydrothermal method. The Co Fe-LDH/GF, as a robust integrated 3 D OER anode, exhibits excellent catalytic activity with the need of low overpotential of 252 and 285 mV to drive current densities of 10 and 100 mA/cm^(2) in 1.0 mol/L KOH, respectively. In addition, it also maintains electrochemical durability for at least 24 h. This work would open up avenues for the development of GF like attractive catalyst supports for oxygen evolution applications. | Biao Deng Jie Liang Luchao Yue Tingshuai Li Qian Liu Yang Liu Shuyan Gao Abdulmohsen Ali Alshehri Khalid Ahmed Alzahrani Yonglan Luo Xuping Sun | 2022 | Chinese Chemical Letters2022,33,2: | 4 |
| 17 | Novel hierarchical structure of MoS_(2)/TiO_(2)/Ti_(3)C_(2)T_(x) composites for dramatically enhanced electromagnetic absorbing properties显示文摘In order to prevent the microwave leakage and mutual interference,more and more microwave absorbing devices are added into the design of electronic products to ensure its routine operation.In this work,we have successfully prepared MoS_(2)/TiO_(2)/Ti_(3)C_(2)T_(x) hierarchical composites by one-pot hydrothermal method and focused on the relationship between structures and electromagnetic absorbing properties.Supported by comprehensive characterizations,M0S_(2) nanosheets were proved to be anchored on the surface and interlayer of Ti_(3)C_(2)T_(x) through a hydrothermal process.Additionally,TiO_(2) nanoparticles were obtained in situ.Due to these hierarchical structures,the MoS_(2)/TiO_(2)/Ti_(3)C_(2)T_(x) composites showed greatly enhanced microwave absorbing performance.The MoS_(2)/TiO_(2)/Ti_(3)C_(2)T_(x) composites exhibit a maximum reflection loss value of -33.5 dB at 10.24 GHz and the effective absorption bandwidth covers 3.1GHz(13.9-17 GHz)at the thickness of 1.0 mm,implying the features of wide frequency and light weight.This work in the hierarchical structure of MoS_(2)/TiO_(2)/Ti_(3)C_(2)T_(x) composites opens a promising door to the exploration of constructing extraordinary electromagnetic wave absorbents. | Heng DU Qipeng ZHANG Biao ZHAO Frank MARKEN Qiancheng GAO Hongxia LU Li GUAN Hailong WANG Gang SHAO Hongliang XU Rui ZHANG Bingbing FAN | 2021 | Journal of Advanced Ceramics2021,10,5: | 4 |
| 18 | Effects of methylphenidate on resting-state brain activity in normal adults: an fMRI study显示文摘Methylphenidate (MPH) is one of the most commonly used stimulants for the treatment of attention deficit hyperactivity disorder (ADHD). Although several studies have evaluated the effects of MPH on human brain activation during specific cognitive tasks using functional magnetic resonance imaging (fMRI), few studies have focused on spontaneous brain activity. In the current study, we investigated the effect of MPH on the intra-regional synchronization of spontaneous brain activity during the resting state in 18 normal adult males. A handedness questionnaire and the Wechsler Adult Intelligence Scale were applied before medication, and a resting-state fMRI scan was obtained 1 h after medication (20 mg MPH or placebo, order counterbalanced between participants). We demonstrated that: (1) there were no significant differences in the performance of behavioral tasks between the MPH and placebo groups; (2) the left middle and superior temporal gyri had stronger MPH-related regional homogeneity (ReHo); and (3) the left lingual gyrus had weaker MPH-related ReHo. Our findings showed that the ReHo in some brain areas changes with MPH compared to placebo in normal adults, even though there are no behavioral differences. This method can be applied to patients with mental illness who may be treated with MPH, and be used to compare the difference between patients taking MPH and normal participants, to help reveal the mechanism of how MPH works. | Yihong Zhu Bin Gao Jianming Hua Weibo Liu Yichao Deng Lijie Zhang Biao Jiang Yufeng Zang | 2013 | Neuroscience Bulletin2013,29,1: | 4 |

| 20 | Improved and excellent CO sensing properties of Cu-doped TiO_2 nanofibers显示文摘Cu-doped TiO2 nanofibers with an average diameter of about 80 nm are synthesized through an electrospinning method. Both anatase and rutile crystallographic structures are found in the fibers based on XRD results. Compared with pure TiO2 nanofibers, the Cu-doped TiO2 nanofibers exhibit improved CO sensing properties at 300°C. The sensitivity of Cu-doped TiO2 nanofibers is up to 3 when the sensor is exposed to 5 ppm CO, and the response and recovery times are about 4 and 8 s, respectively. Good selectivity is also observed in our investigations. These results indicate that the Cu-doped TiO2 nanofibers can be used to fabricate high performance CO sensors in practice. | WANG Biao ZHAO YuDong HU LiMing CAO JunSheng GAO FengLi LIU Yun WANG LiJun | 2010 | Chinese Science Bulletin2010,55,3: | 3 |
