| 1 | Selective depression action of taurine in flotation separation of specularite and chlorite显示文摘Chlorite,as the most representative gangue mineral associated with specularite,of which the separation of these two minerals is difficult.This paper investigated the depression effect of taurine on specularite/chlorite separation via flotation experiments,adsorption tests,contact angle measurements,Zeta potential detection,FT-IR measurements,and XPS analyses.The results of single mineral flotation indicated that chlorite could be depressed selectively by taurine with the recovery of less than 30%,but the floatability of specularite remains high with recovery rate of 81.77%at pH 10.The artificial mixed mineral flotation results confirmed the effectiveness of taurine as a depressant.Surface adsorption,contact angle,and Zeta potential detection revealed taurine primarily adsorbs on the chlorite surface,which hampered the DDA’s subsequent adsorption and results in the chlorite’s poor floatability.The FT-IR spectra and XPS analyses provided further proof that taurine adsorbed on chlorite surface as an electron donor,and part of the electrons transferred from the sulfonic acid group of taurine to metal ions during the adsorption process.In addition,the hydrogen bond between amino-group of taurine and O ions in chlorite surface was also formed in the adsorption process.Finally,optimized adsorption configurations of taurine on chlorite surfaces were proposed. | Mingyang Li Cheng Yang Zhaoyang Wu Xiangpeng Gao Xiong Tong Xiankun Yu Hongming Long | 2022 | International Journal of Mining Science and Technology2022，32，3： | 4 |

| 5 | A Hu sheep genome with the first ovine Y chromosome reveal introgression history after sheep domestication显示文摘The Y chromosome plays key roles in male fertility and reflects the evolutionary history of paternal lineages.Here,we present a de novo genome assembly of the Hu sheep with the first draft assembly of ovine Y chromosome(o MSY),using nanopore sequencing and Hi-C technologies.The o MSY that we generated spans 10.6 Mb from which 775 Y-SNPs were identified by applying a large panel of whole genome sequences from worldwide sheep and wild Iranian mouflons.Three major paternal lineages(HY1a,HY1b and HY2)were defined across domestic sheep,of which HY2 was newly detected.Surprisingly,HY2 forms a monophyletic clade with the Iranian mouflons and is highly divergent from both HY1a and HY1b.Demographic analysis of Y chromosomes,mitochondrial and nuclear genomes confirmed that HY2 and the maternal counterpart of lineage C represented a distinct wild mouflon population in Iran that diverge from the direct ancestor of domestic sheep,the wild mouflons in Southeastern Anatolia.Our results suggest that wild Iranian mouflons had introgressed into domestic sheep and thereby introduced this Iranian mouflon specific lineage carrying HY2 to both East Asian and Africa sheep populations. | Ran Li Peng Yang Ming Li Wenwen Fang Xiangpeng Yue Hojjat Asadollahpour Nanaei Shangquan Gan Duo Du Yudong Cai Xuelei Dai Qimeng Yang Chunna Cao Weidong Deng Sangang He Wenrong Li Runlin Ma Mingjun Liu Yu Jiang | 2021 | Science China(Life Sciences)2021，64，7： | 1 |

| 7 | Large-diameter indium antimonide microwire based broadband and robust optical switch显示文摘Various nanophotonic devices based on semiconductor wires with a diameter of several ten nanometers have been studied.Nevertheless,studying the optoelectronics properties and performance of such devices based on large-diameter wires is interesting and meaningful.Here,we successfully grew the micronsized indium antimonide(InSb) wires,and examined their nonlinear optical properties by Z-scan and I-scan(power-dependent) methods within the wavelength range of 0.8-2.8 μm.Furthermore,we demonstrated InSb micro wires(MWs) working as an effective and robust optical switch within 1-2.8 μm wavelength.The findings can open possibilities for research on more large-diameter MWs made from other semiconductor materials for photonic and electronic devices. | Fei Lou Xiangpeng Cui Xinyue Sheng Chunyan Jia Shuaiyi Zhang Xia Wang Vladislav Khayrudinov Baitao Zhang Shande Liu Wing Yim Tam Harri Lipsanen He Yang Jingliang He | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，2： | 0 |
| 8 | Development and application of the Baosteel mechanical descaling technology显示文摘During the hot rolling process,o xides are formed on the surface of metal products.These oxides,which are commonly called scales,must be eliminated before other post-processing. Currently,chemical pickling is the most widespread technology for descaling.However,chemical pickling depicts several drawbacks such as severe pollution, high cost, and unstable quality.Consequently,Baosteel initiated the Baosteel mechanical descaling( BMD)technology research in 2009.The BMD technology uses a water jet containing abrasive to eliminate the scales.The metal surface after BMD processing achieves an excellent surface quality with grade of Sa3.0 and satisfies the requirement of subsequent processes such as stamping,coating,and cold rolling. In this study, the development history,process feature,and industrial application of the BMD technology are presented. In addition,further development and prospects of the BMD technology are forecasted. | DUAN Mingnan LI Shanqing CHEN Shenghe FANG Xin YANG Xiangpeng XU Jianghua | 2018 | Baosteel Technical Research2018，12，1： | 0 |

| 10 | A statistical analysis of conjugate equatorial plasma bubbles based on 630 nm airglow observations显示文摘Using the observations of the 630-nm all-sky imagers(ASIs)located in the geomagnetic conjugate points in the American sector from 2014 to 2017,this study statistically analyzed the features of conjugate equatorial plasma bubbles(EPBs),including their occurrence rate,zonal width,location and zonal drift velocity.The results show that the occurrence rate of the EPBs that occur simultaneously at geomagnetic conjugate points is~84%.The zonal widths of the EPBs are mainly~100 km,and the width differences of EPBs between the northern and southern hemispheres are mainly within±30 km.The zonal displacements of the center locations of the northern and southern EPBs are within±50 km.The zonal drift velocities of the northern and southern EPBs are nearly equal.However,it should be noted that the velocity of the EPBs in the northern hemisphere is 10%faster than that in the southern hemisphere.The results suggest that conjugate EPBs are common.Moreover,the non-conjugate EPBs in the northern and southern hemisphere can occur occasionally,which is probably associated with the different ionospheric backgrounds between the two hemispheres.The features of the conjugate EPBs as shown in this study provides support for the nowcasting of EPBs in the conjugate hemispheres. | Zukang DAI Tao YU Na YANG Jin WANG Di FU Xiangpeng FENG Yutao FENG | 2023 | Science China Earth Sciences2023，66，3： | 0 |
| 11 | An optimization of ultra-sonication-assisted extraction from flowers of Apocynum venetum in targeting to amount of free amino acids determined by UPLC-MS/MS显示文摘Amino acids are naturally occurring compounds in many edible or medicinal plants,which possess a variety of nutraceutical effects in human.Here,a method of ultrasound-assisted extraction was optimized using Box-Behnken design of response surface methodology in maximizing the yield of free amino acids deriving from flowers of Apocynum venetum L.Under the optimal condition of ultrasound-assisted extraction,i.e.187.5 W of ultrasonic power,31.93 min of extraction time,and 0.47 mg/ml of solid-liquid ratio,the experimental yield of extractive was 287.17±0.205 mg/g,which was in close agreement with the value,as predicted by the established model.In addition,a hydrophilic interaction ultra-high performance liquid chromatography coupled with QqQ-MS/MS method was developed and validated for simultaneous quantification of 20 types of amino acids without derivatization contained in A.venetum flowers.The analytical method was validated by matrix effect,linearity,limit of detection,limit of quantification,precision,repeatability,stability,and recovery.The analysis results showed that A.venetum flower was rich in free amino acids of~3%of total dried weight,and which contained leucine(13.7 g/mg),isoleucine(7.9 g/mg),and lysine(2.2 g/mg)as the most abundant amino acids.Thus,A.venetum flower could provide beneficial nutrient values for human health,e.g.adult weight maintenance or glucose homeostasis. | Yan Jin Caroline Yang Wang Weihui Hu Yun Huang Miranda Li Xu Huaiyou Wang Xiangpeng Kong Yicun Chen Tina Tingxia Dong Qiwei Qin Karl Wah Keung Tsim | 2019 | Food Quality and Safety2019，3，1： | 0 |

| 13 | Lightning and deep convective activities over the Tibetan Plateau显示文摘Convections over the Tibetan Plateau play a crucial role in the energy and material exchange between the troposphere and stratosphere,impacting the rain-bearing synoptic systems over eastern China.Lightning can be used as a key indicator of strong convection and therefore its characteristics and relationship with convection over the plateau are of great interest to researchers.The panorama of lightning activity over the plateau has been revealed by recent studies using the optical observation data from the satellite. | Dong Zheng Yijun Zhang Yang Zhang Wen Yao Fei Wang Weitao Lyu Qing Meng Xiangpeng Fan Ying Ma Jun Yang | 2020 | National Science Review2020，7，3： | 0 |
| 14 | Host cyclophilin A facilitates SARS-CoV-2 infection by binding and stabilizing spike on virions显示文摘Dear Editor,The novel coronavirus SARS-CoV-2 rapidly evolutes to increase its infectivity and transmissibility,facilitates its immune escape,impairs vaccine efficacy,and currently causes repeated infections in human,which is mainly determined by the accumulated mutations in spike(S).1 Transmembrane S is a heavily glycosylated protein on the surface of the virion as homotrimer,responsible for binding to human angiotensin-converting enzyme 2(hACE2)receptor.2 While the architecture of S trimers has been well studied,how the stability of S is regulated by potential host factors remains unknown. | Xiangpeng Sheng Fang Zhu Hong Peng Fan Yang Yi Yang Cong Yang Zhen Wang Wei Chen Deyin Guo Ronggui Hu | 2024 | Signal Transduction and Targeted Therapy2024，9，1： | 0 |
| 15 | Comparative pluripotency analysis of mouse embryonic stem cells derived from wild-type and infertile hermaphrodite somatic cell nuclear transfer blastocysts显示文摘Therapeutic cloning, whereby embryonic stem cells (ESCs) are derived from patient-specific cloned blastocysts via somatic cell nuclear transfer (SCNT), holds great promise for treating many human diseases using regenerative medicine. Teratoma formation and germline transmission have been used to confirm the pluripotency of mouse stem cells, but human embryonic stem cells (hESCs) have not been proven to be fully pluripotent owing to the ethical impossibility of testing for germ line transmission, which would be the strongest evidence for full pluripotency. Therefore, formation of differentiated cells from the three somatic germ layers within a teratoma is taken as the best indicator of pluripotency in hESC lines. The possibility that these lines lack full multi-or pluripotency has not yet been evaluated. In this study, we established 16 mouse ESC lines, including 3 genetically defective nuclear transfer- ESC (ntESC) lines derived from SCNT blastocysts of infertile hermaphrodite F1 mice and 13 ntESC lines derived from SCNT blastocysts of normal F1 mice. We found that the defective ntESCs expressed all in vitro markers of pluripotency and could form teratomas that included derivatives from all three germ layers, but could not be transmitted via the germ line, in contrast with normal ntESCs. Our results indicate that teratoma formation assays with hESCs might be an insufficient standard to assess full pluripotency, although they do define multipotency to some degree. More rigorous standards are required to assess the safety of hESCs for therapeutic cloning. | FAN Yong TONG Man ZHAO ChunLi DING ChenHui HAO Jie LV Zhuo DAI XiangPeng HAI Tang LI XueMei YAO RuQiang YU Yang LI ZanDong WANG Liu ALICE Jouneau ZHOU Qi | 2008 | Chinese Science Bulletin2008，53，23： | 0 |
