| 1 | Geochronological and geochemical constraints on the Cuonadong leucogranite, eastern Himalaya显示文摘First comprehensive investigations of the Cuonadong leucogranite exposed in North Himalayan gneiss dome of southern Tibet are presented in this study.The SIMS U–Pb ages of oscillatory zircon rims scatter in a wide range from 34.1 to 16.0 Ma, and the Cuonadong leucogranite probably emplaced at 16.0 Ma. High-precision ^(40)Ar/^(39)Ar dating on a muscovite sample yields an essentially flat age spectrum with consistent plateau and isochron ages, indicating that the Cuonadong leucogranite cooled below 450 °C at 14 Ma. Based on the youngest zircon U–Pb age and muscovite^(40)Ar/^(39)Ar age, the Cuonadong leucogranite experienced rapid cooling with a rate of 119 °C/Myr from 16 to 14 Ma. The geochronological data of this undeformed leucogranite also suggest that the ductile extension of the South Tibetan Detachment System in the eastern Himalaya ceased by ca. 14 Ma. Furthermore,the initial Sr–Nd isotopic compositions and Nd model ages demonstrate that the leucogranite was derived from metapelitic source within the Greater Himalayan Crystalline Complex. The distinct Ba depletion with high Rb/Sr ratios and negative Eu anomalies make it clear that the leucogranite melts were generated by breakdown of muscovite under fluid-absent conditions. | Jiajia Xie Huaning Qiu Xiujuan Bai Wanfeng Zhang Qiang Wang Xiaoping Xia | 2018 | Acta Geochimica2018，37，3： | 7 |
| 2 | New discrimination diagrams for basalts based on big data research显示文摘In recent days,discrimination diagrams have been widely used for tracing the tectonic settings and origins of basalts from orogenic belts.However,conventional discrimination diagrams are not accurate enough.Here,we reported six new discrimination diagrams obtained from the global database using data mining methods.For most individual diagrams,island arc basalt can be nearly 100%was identified,whereas ocean island basalt and midocean ridge basalt can be discriminated from each other with less than 10%of overlap,under a confidence coefficient of 85%.Using the six new discrimination diagrams together,basalts of different origins can be efficiently identified. | Qi Zhang Weidong Sun Yong Zhao Fanglin Yuan Shoutao Jiao Wanfeng Chen | 2019 | Big Earth Data2019，3，1： | 4 |
| 3 | Occurrence and fate of typical antibiotics in wastewater treatment plants in Harbin, North-east China显示文摘As a new pollutant, antibiotics in the environment and their removal in wastewater treatment plants (WWTPs) have gained considerable attention. However, few studies investigated antibiotics in the north-eastern areas of China. By employing high-performance liquid chromatography-tandem mass spectrometry, the concentration distribution and removal of 12 antibiotics belonging to four types (cephalosporins, sulfonamides, fluoroquinolones, and macrolides) were investigated in influents and effluents as well as the removal efficiencies of four typical treatment processes in 18 wastewater treatment plants of Harbin City, north-eastem China. Macrolides and fluoroquinolones presented relatively higher detection concentrations and rates both in the water and in the sludge phases. Sulfonamides and cephalosporins displayed higher detection concentrations in the water phase. The representative antibiotics in influents and effluents included ROX, NOR, OFL, SMX, AZI, and CLA, with detection rates above 95%. The detection rates of the other six antibiotics exceeded 30%. In the sludge, the other five antibiotics, except SMX, presented relatively higher detection concentrations and rates, with detection rates greater than 95%. For cephalosporin, the detection rates of CTX and CFM in the sludge were 0. The removal efficiencies for the 12 antibiotics differed greatly, with average values ranging from 30% to 80% and the highest values for cephalosporin. The removal of antibiotics did not differ significantly among the four different treatment processes. | Weihua Wang Wanfeng Zhang Hong Liang Dawen Gao | 2019 | Frontiers of Environmental Science & Engineering2019，13，3： | 2 |
| 4 | Dealloying-constructed hierarchical nanoporous bismuth-antimony anode for potassium ion batteries显示文摘Bi-Sb alloys are appealing anode materials for potassium ion batteries(PIBs)but challenged by their enormous volumetric variation during operation.Herein,a facile one-step dealloying protocol was devised and utilized to prepare the Bi-Sb alloys that manifest an exotic bicontinuous hierarchical nanoporous(np)microstructure ideal for volume-change mitigation and K+transport percolation.The growth mechanism fostering the peculiar morphology of the np-(Bi,Sb)alloys was investigated and clarified via operando X-ray(XRD)and ex-situ scanning electron microscopy(SEM).In particular,the np-Bi6Sb2 electrode,optimized for comprehensive electrochemical performance,achieves decent reversible capacities and a superior lifespan,as benchmarked with the monometallic references and other Bi-Sb alloy electrodes.The(de)potassiation mechanism of the np-(Bi,Sb)alloys was studied by operando XRD and further rationalized by density functional theory(DFT)calculations,whereby a homogeneous(segregation-free)and robust two-step electrochemically-driven phase transformations’catenation of(Bi,Sb)↔K(Bi,Sb)2↔K3(Bi,Sb)was reliably established to substantiate the outstanding reversibility of the np-(Bi,Sb)anodes in PIBs. | Hui Gao Kuibo Yin Zhiyuan Guo Ying Zhang Wensheng Ma Wanfeng Yang Ke Sun Zhangquan Peng Zhonghua Zhang | 2021 | Fundamental Research2021，1，4： | 2 |

| 8 | A H_(2)O-in-zircon perspective on the heterogeneous water content of crust-derived magmas in southern Tibet显示文摘Geophysical and geochemical evidence revealed that certain amounts of water are stored in the Earth’s interior,and its distribution exhibits temporal and spatial differences.Recent studies indicate that the H_(2)O-in-zircon has a potential to reveal magma water content.Using secondary ion mass spectrometry(SIMS),we analyzed the zircon water content and oxygen isotopes in granitoids(two-mica granite,quartz monzonite,diorite,and granodiorite)from southern Tibet.The results are used to explore the diversity of water content in crust-derived magmas,which is also supported by the LA-ICPMS zircon trace element analysis.There are low zircon water contents for two partial melting products of the ancient crust(peak at 85 and300 ppm,respectively).Meanwhile,there are high H_(2)O-in-zircon peaks(435 and 475 ppm,respectively)for two partial melting products of the juvenile crust.The calculated radiation damage accumulation in these zircon grains is below 3×10^(15)αdecay events mg^(–1),suggesting that the zircon grains are well crystalline.There is no correlation between REE+Y and H+P,indicating that the mechanism of charge balance for water uptaking into zircon,in which the excess of REE+Y to P controls Hcontent,is not applicable to the studied samples.The degree of magma fractionation cannot account for the zircon water content variation,because there is no co-variation between zircon Hf and H_(2)O contents.Similarly,the degree of partial melting was unlikely to be responsible for the H_(2)O-in-zircon distinction.We interpret that the H_(2)O-in-zircon variation reflects the influence of melting mode(dehydration vs.water-fluxed)and water content in the crustal source.In the Late Devonian,dehydration melting of the crustal rocks was facilitated at elevated temperatures,which produced magmas with the lowest water contents.Water-fluxed melting of the ancient crust would produce relatively“drier”magma than water-fluxed melting of the juvenile crust. | Juntong MENG Xiaoping XIA Lin MA Ziqi JIANG Jian XU Zexian CUI Qing YANG Wanfeng ZHANG Le ZHANG | 2021 | Science China Earth Sciences2021，64，7： | 1 |

| 13 | Comparative study on the mRNA expression of Pinus massoniana infected by Bursaphelenchus xylophilus显示文摘Pine wilt disease(PWD)is a devastating disease affecting the growth of Pinus massoniana,often leading to withering and death.To reveal the changes involved during disease progression,we investigated the mRNA expression profile of P.massoniana infested by Bursaphelenchus xylophilus.The infestation resulted in the downregulation of genes involved in interactions with pathogenic pathways such as disease resistance gene,CC-NBS-LRR resistancelike protein,and the gene encoding a putative nematode resistance protein.Increased infestation pressure(number of nematodes inoculated)caused a continuous decline in the gene expression of stem samples.An infestation of P.massoniana also resulted in a pathway enrichment of genes involved in phenylpropanoid metabolism and flavonoid biosynthesis,which in turn reduced the levels of total phenols and total flavonoids.A downregulation of auxin responsive family protein was observed in infested samples,which resulted in a suppression of plant growth.Thus,upon B.xylophilus infestation,a downregulation of genes associated with the recognition of pathogens,PWD resistance,and growth regulation was observed in P.massoniana,together with a decrease in the levels of phytoalexinlike secondary substances,all of which resulted in withering and ultimately death of P.massoniana. | Wanfeng Xie Guanghong Liang Aizhen Huang Feiping Zhang Wenshuo Guo | 2020 | Journal of Forestry Research2020，31，1： | 1 |

| 15 | Comparative study on nutrient composition and antioxidant capacity of potato based on geographical and climatic factors显示文摘Potatoes are consumed in the human diet,but the environmental effects on the nutrient content of their tubers are not known.Five potato varieties from China(Chongqing,Dingxi,Qiqihar,Enshi,and Ulanqab)were selected to compare their nutritional components and antioxidant capacity and to explore the correlation between nutrition and local rainfall,humidity,temperature,and light time.The results indicated the Qiqihar cultivar presents significantly higher antioxidant capacity,and has the most elevated protein and soluble sugar contents.The total phenol(TPC)(325.07μg/g)and carotenoid contents(54.93μg/100g)of the Ulanqab cultivar were the highest.The Dingxi cultivar reveals the highest total flavonoids(TFC)(168.94μg/g),K,Mg,and P contents.The ascorbic acid content(26.09 mg/100g)was the highest in the Chongqing cultivar,and the contents of starch,Ca,total acid,and water were also prominent.The amino acid content(7.350%)in the Enshi cultivar is higher.It was found that soluble sugar was significantly correlated with humidity,temperature,and light time;carotenoids were affected considerably by rainfall;ascorbic acid has a strong correlation with temperature;TPC was moderately associated with humidity and light time.To summarize,tubers’nutrient composition and antioxidant capacity vary with geographical location and climate of origin.This study will help provide a theoretical basis for selecting geographical areas for potato planting and exploring the complex interactive factors between environment and vegetable attributes. | Bing Zhang Ayesha Murtaza Aamir Iqbal Jiao Zhang Tingting Bai Wanlu Ma Xiaoyun Xu Siyi Pan Wanfeng Hu | 2022 | Food Bioscience2022，46，2： | 1 |

| 20 | ARHGEF38 as a novel biomarker to predict aggressive prostate cancer显示文摘Prostate cancer(PCa)metastasis is considered the leading cause of cancer death in males.Therapeutic strategies and diagnosis for stage-specific PCa have not been well understood.Rho guanine nucleotide exchange factor 38(ARHGEF38)is related to tumor cell polarization and is frequently expressed in PCa.Microarray data of PCa were downloaded from GEO and TCGA databases.A total of 243 DEGs were screened,of which,32 genes were upregulated.The results of enrichment analysis showed the participation of these DEGs in the tumor cell metastasis pathway.ARHGEF38 was significantly up-regulated in the four most prevalent cancers worldwide(p<0.05),and its expression was higher in the tumor samples with higher Gleason score(GS).IHC,qRT-PCR,and western-blot analyses showed the higher expression of ARHGEF38 in PCa than benign prostatic hyperplasia(BPH).In addition,IHC results demonstrated a higher expression of ARHGEF38 in high-grade PCa than the low-grade PCa. | Kun Liu Aixiang Wang Longke Ran Wanfeng Zhang Song Jing Yujing Wang Xianqin Zhang Geli Liu Wang Sen Fangzhou Song | 2020 | Genes & Diseases2020，7，2： | 0 |
