| 1 | Coesite in the eclogite and schist of the Atantayi Valley, southwestern Tianshan, China显示文摘Coesite is an indicator mineral of ultra-high-pressure metamorphism. Since coesite was reported in the Habutengsu Valley, we have also found it in eclogite and schist from the Atantayi Valley in the southwestern Tianshan, China. Petrographic and micro-Raman analyses were carried out for the Atantayi metamorphic rocks and coesite was recognized in the predominant rock types, i.e. schist and eclogite, from three sections. The coesite-bearing schist consists mainly of garnet, Na-Ca amphibole, quartz, white mica and albite; the coesite-bearing eclogite is mainly composed of omphacite, garnet, glaucophane and zoisite. The coesite occurs as various mineral inclusions within porphyroblastic garnet. Findings of coesite in eclogite and associated schist indicate not only the regional in situ formation of the Atantayi ultra-high-pressure eclogite, but also the large areal extent of ultra-high-pressure metamorphism in southwestern Tianshan, extending up to 10 km north-south and 60-80 km east-west. | LÜ Zeng ZHANG LiFei | 2012 | Chinese Science Bulletin2012，57，13： | 9 |
| 2 | Differential Evolution of High-Pressure and Ultrahigh-Pressure Metapelites from Habutengsu, Chinese Western Tianshan: Phase Equilibria Modelling and ^(40)Ar/^(39)Ar Geochronology显示文摘Metapelite is one of the predominant rock types in the high-pressure–ultrahigh-pressure(HP–UHP) metamorphic belt of western Tianshan, NW China; however, the spatial and temporal variations of this belt during metamorphism are poorly understood. In this study, we present comparative petrological studies and 40Ar/39 Ar geochronology of HP and UHP pelitic schist exposed along the Habutengsu valley. The schist mainly comprises quartz, white mica, garnet, albite and bluish amphibole. In the Mn O–Na2O–Ca O–K2O–Fe O–Mg O–Al2O3–Si O2–H2O(Mn NCKFMASH) system, P–T pseudosections were constructed using THERMOCALC 333 for two representative pelitic schists. The results demonstrate that there was a break in the peak metamorphic pressures in the Habutengsu area. The northern schist has experienced UHP metamorphism, consistent with the presence of coesite in the same section, while the southern one formed at lower pressures that stabilized the quartz. This result supports the previous finding of a metamorphic gradient through the HP–UHP metamorphic belt of the Chinese western Tianshan by the authors. Additionally, phengite in the northern schist was modelled as having a Si content of 3.55–3.70(a.p.f.u.) at the peak stage, a value much higher than that of oriented matrix phengite(Si content 3.32–3.38 a.p.f.u.). This indicates that the phengite flakes in the UHP schist were subjected to recrystallization during exhumation, which is consistent with the presence of phengite aggregates surrounding garnet porphyroblast. The 40Ar/39 Ar age spectra of white mica(dominantly phengite) from the two schists exhibit similar plateau ages of ca. 315 Ma, which is interpreted as the timing of a tectonometamorphic event that occurred during the exhumation of the HP–UHP metamorphic belt of the Chinese western Tianshan. | Lü Zeng ZHANG Lifei | 2016 | Acta Geologica Sinica(English Edition)2016，90，2： | 3 |

| 13 | Preparation and Photocatalytic Application of High Temperature Stabilized ZrSiO_4@TiO_2 Hybrid Nanostructure显示文摘A new ZrSiO4@TiO2 hybrid nanostructure was prepared by a heterogeneous flocculation method. Phytic acid was introduced to modify the surface charging of the components for hybrid assembly. The obtained powder was coated on ceramic tiles and fired at 900 ℃ to fabricate photocatalytic ceramic. Experimental results show that anatase TiO2 in the composite powder has high thermal stability until 1 200 ℃. ZrSiO4 matrix prevents the mass transfer of anatase TiO2 at high temperature and greatly retards the phase transition of anatase to rutile. Besides, the photocatalytic ceramic shows apparent activities for the degradation of methyl orange under ultra-violet irradiation. | 彭诚 FANG Peiyu ZENG Zhichao Lü Ming 吴建青 | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，4： | 0 |
| 14 | Impacts of temperatures and phosphoric-acid modification to the physicochemical properties of biochar for excellent sulfadiazine adsorption显示文摘The textural properties and surface chemistry of phosphoric acid-modified biochars(PABCs)prepared at different pyrolysis temperatures(500-700℃)were studied based on the results obtained from XRD,SEM,BET,FT-IR,Raman,XPS and elements analyses.PABCs prepared at higher temperatures tended to possess a bigger proportion of microporous structure.The adsorption capacity and initial rate of PABCs for sulfadiazine(SDZ)were notably improved to 139.2 mg/g and 9.66 mg/(g min)as calculated from the Langmuir model.The adsorption equilibrium time was only one quarter of that without modification.The H_(3)PO_(4) modification was advantageous to produce phosphate and break functional groups to form disordered carbon structure abundant of micropores.The enhancement in the adsorption of SDZ was due to the confinement effect of hydrophobic cavities from the mircoporous structure and theπ-πelectron-donor-acceptor interaction.Specially,PABCs exhibited stable adsorption capacities at a wide pH range(3.0-9.0)or relatively high concentrations of coexisting ions. | Xue-Yu Zeng Yu Wang Rong-Xin Li Hai-Lei Cao Ya-Feng Li Jian Lü | 2022 | Biochar2022，4，1： | 3 |
| 15 | Crustal S-wave velocity structure of the Yellowstone region using a seismic ambient noise method显示文摘The Yellowstone volcano is one of the largest active volcanoes in the world,and its potential hazards demand detailed seismological and geodetic studies.Previous studies with travel time tomography and receiver functions have revealed a low-velocity layer in the crust beneath the Yellowstone volcano,suggesting the presence of a magma chamber at depth.We use ambient seismic noise from regional seismic stations to retrieve short-period surface waves and then study the shallow shear velocity structure of the Yellowstone region by surface wave dispersion analysis.We first obtained a crustal model of the area outside of the Yellowstone volcano and then constructed an absolute shear wave velocity structure in combination with receiver function results for the crust beneath the Yellowstone volcano.The velocity model shows a low-velocity layer with shear velocity at around1.3 km/s,suggesting that a large-scale magma chamber exists at shallow levels within the crust of the Yellowstone volcanic region. | Yan Lü Sidao Ni Jun Xie Yingjie Xia Xiangfang Zeng Bin Liu | 2013 | Earthquake Science2013，26，5： | 2 |

| 17 | Double role of CoOeCo_(4)N hetero-nanocages as sulfur host for lithiumsulfur batteries显示文摘Lithium-sulfur batteries(LiSBs)are widely deemed as the most promising energy storage devices to substitute for traditional Li-ion batteries.However,its wide application is impeded by the soluble lithium polysulfides(LiPSs),which is called the shuttle effect,and the irregular distribution of final product Li_(2)S.Herein,based on the interfaces engineering,CoO-Co_(4)N hetero-nanocages are used as the sulfur host for LiSBs.Taking advantage of the polarity of CoO with the conductivity of Co_(4)N,CoO-Co_(4)N nanocages not only can provide large void space for sulfur volume fluctuation,but also can adsorb polysulfides and simultaneously regulate the nucleation of solid Li_(2)S by the‘trapping-diffusion-conversion’mechanism,which significantly enhances the redox kinetic of LiSBs and the utilization of active materials.Eventually,LiSBs with CoO-Co_(4)N nanocages host exhibit higher rate capacity(737 mAh·g^(-1) at 2 C)and cycling stability(662 mAh·g^(-1) at^(-1) C after 350 cycles).Even when the areal sulfur loading is as high as 3.0 mg cm^(-2),a high capacity of 713 mAh·g^(-1) can still be achieved after 100 cycles at 0.2 C.This host with sufficient polar-conductive interfaces expands‘trapping-diffusion-conversion’concept for the design of fast kinetic and high performance LSBs. | Yi-Ming Lu Jin-Lin Yang Shi-Xi Zhao Xiang-Tian Zeng Lü-Qiang Yu Chao Huang | 2021 | Journal of Materiomics2021，7，6： | 0 |

| 19 | A huge oceanic-type UHP metamorphic belt in southwestern Tianshan, China: Peak metamorphic age and P-T path显示文摘Recent progress in the study of the UHP metamorphic belt in southwestern Tianshan,China,is summarized in this paper.This about 80-km-long and over 10-km-wide UHP belt has been recognized by the discovery of coesite,coesite pseudomorphs and other UHP minerals.It is the largest oceanic-type UHP metamorphic belt reported so far.It has formed due to northward subduction of the Tianshan Paleo-Ocean.U-Pb dating of metamorphic rims of zircons from a coesite-bearing garnet-phengite schist yields a peak UHP metamorphic ages of 320±3.7 Ma.Combined with ages of 233–226 Ma obtained from rims of zircons from retrograded eclogites,a long retrograde metamorphic evolution(>70 Ma)has been revealed.According to phase equilibria modeling,the P-T paths of both coesite-bearing eclogites and garnet-phengite schists are characterized by thermal relaxation,i.e.,the metamorphic temperature peak lags behind the pressure peak,indicating that the UHP rocks experienced slow and long heating and decompression during exhumation in the subduction channel.On the basis of the field observation that a small amount of eclogite lenses is wrapped in large volumes of metapelites,and the similar P-T paths of both rock types,we propose that the exhumation of the UHP eclogites from southwestern Tianshan,China,may have resulted from the exhumation of large volumes of low-density metapelites,which carried the denser eclogites to the Earth’s surface. | ZHANG LiFei DU JinXue Lü Zeng YANG Xin GOU LongLong XIA Bin CHEN ZhenYu WEI ChunJing SONG ShuGuang | 2013 | Chinese Science Bulletin2013，58，35： | 19 |
