| 1 | Plankton community composition in the Three Gorges Reservoir Region revealed by PCR-DGGE and its relationships with environmental factors显示文摘To explore the relationships between community composition and the environment in a reservoir ecosystem, plankton communities from the Three Gorges Reservoir Region were studied by PCR-denaturing gradient gel electrophoresis fingerprinting. Bacterial and eukaryotic operational taxonomic units (OTUs), generated by DGGE analysis of the PCR-amplified 16S and 18S rRNA genes, were used as surrogates for the dominant 'biodiversity units'. OTU composition among the sites was heterogeneous; 46.7% of the total bacterial OTUs (45) and 64.1% of the eukaryotic OTUs (39) were identified in less than half of the sampling sites. Unweighted pair group method with arithmetic averages (UPGMA) clustering of the OTUs suggested that the plankton communities in the Xiangxi Rive sites were not always significantly different from those from the Yangtze River sites, despite clear differences in their environmental characterizations. Canonical correspondence analysis (CCA) was applied to further investigate the relationships between OTU composition and the environmental factors. The first two CCA ordination axes suggested that the bacterial community composition was primarily correlated with the variables of NO3--N, dissolved oxygen (DO), and SiO32--Si, whereas, the eukaryotic community was mainly correlated with the concentrations of DO, PO43--P, and SiO32--Si. | YAN Qingyun YU Yuhe FENG Weisong YU Zhigang CHEN Hongtao | 2008 | Journal of Environmental Sciences2008，20，6： | 27 |
| 2 | Adsorption of mixed cationic-nonionic surfactant and its effect on bentonite structure显示文摘The adsorption of cationic-nonionic mixed surfactant onto bentonite and its effect on bentonite structure were investigated.The objective was to improve the understanding of surfactant behavior on clay mineral for its possible use in remediation technologies of soil and groundwater contaminated by toxic organic compounds.The cationic surfactant used was hexadecylpyridinium bromide(HDPB),and the nonionic surfactant was Triton X-100(TX100).Adsorption of TX100 was enhanced significantly by the addition of HDPB,but this enhancement decreased with an increase in the fraction of the cationic surfactant.Part of HDPB was replaced by TX100 which decreased the adsorption of HDPB.However,the total adsorbed amount of the mixed surfactant was still increased substantially,indicating the synergistic effect between the cationic and nonionic surfactants.The surfactant-modified bentonite was characterized by Brunauer-Emmett-Teller specific surface area measurement,Fourier transform infrared spectroscopy,and thermogravimetric-derivative thermogravimetric/differential thermal analyses.Surfactant intercalation was found to decrease the bentonite specific surface area,pore volume,and surface roughness and irregularities,as calculated by nitrogen adsorption-desorption isotherms.The co-adsorption of the cationic and nonionic surfactants increased the ordering conformation of the adsorbed surfactants on bentonite,but decreased the thermal stability of the organobentonite system. | Yaxin Zhang Yan Zhao Yong Zhu Huayong Wu Hongtao Wang Wenjing Lu | 2012 | Journal of Environmental Sciences2012，24，8： | 12 |
| 3 | Domain structure and defects of highly ordered Bi_4Si_3O_(12) micro-crystals显示文摘Highly ordered Bi4Si3O12 micro-crystals were prepared at normal atmosphere. Phase identification of the prepared crystals was accomplished by X-ray diffractometer (XRD). Domain structure and defects were characterized by environmental scanning electron microscopy (ESEM). XRD shows that the obtained micro-crystals are of eulytite structure with chemical formulation of Bi4Si3O12. A highly ordered growth pattern is confirmed due to the faster growth of the {124} faces than that of the {204} faces by ESEM. The growing process of the domain structure is of pollen parent and filial generation pattern. The filial generations of Bi4Si3O12 crystals are generated from the pollen parent. Cracks generate from the defect areas and propagate along the {124} faces due to their lower binding energy under a proper temperature gradient, contributing to the total transcrystalline fracture. It is confirmed that the generation and development of the voids in the crystal grains can be developed when unmatched dimensions of the two opposite faces are formed. And the development of the voids is dependent on the dimensions and orientations of the two opposite faces. | TIAN QingQuan, WANG XiuFeng, YU ChengLong, JIANG HongTao, ZHANG ZhengGuang, WANG Yan & LIN SheBao School of Materials Science and Engineering, Shaanxi University of Science & Technology, Xi’an 710021, China | 2009 | Science China(Technological Sciences)2009，52，8： | 8 |
| 4 | Preparation and Bloating Mechanism of Porous Ultra-lightweight Ceramsite by Dehydrated Sewage Sludge and Yellow River Sediments显示文摘To solve the disposal problems of solid wastes, dehydrated sewage sludge and Yellow River sediments were tested as components for production of ultra-lightweight ceramsite. The effects of Yellow River sediments addition on the characteristics of ceramsite were investigated. Ceramsite with different Yellow River sediments additions was characterized using thermal analysis, X-ray diffraction, morphological structures analyses, pore size distributions and porosity analyses. Chemical components, especially ratios of Si O2 + Al2O3/Flux, were used to explain the glassy shell formation, physical properties and pores distribution of ultralightweight ceramsite; physical forces for instance expansion force and frictional resistance which combined with Si O2 + Al2O3/Flux ratios were used to explain the bloating mechanism. Results showed that the maximum addition of Yellow River sediments for making ultra-lightweight ceramsite was 35%. Macropores(between 0.226 μm and 0.554 μm) of ultra-lightweight ceramsite were dominant in the pore structures of ultra-lightweight ceramsite and its porosity was up to 67.7%. Physical force of expansion force was constant with the variation of Yellow River sediments content and physical force of frictional resistance was decreased with the increase of Yellow River sediments addition. The relationship between expansion and frictional resistance could determine the expansion rate of ceramsite. Larger pores inside the ceramsite bodies could be obtained as Yellow River sediments additions ranged from 10% to 30%. Ceramsite with higher Yellow River sediments additions of 40%(Si O2 + Al2O3/Flux ratios 4.25) became denser and have lower porosity. Crystal components analysis proved that the sintering process made some components of raw materials transfer into other crystals having better thermostability. | 岳东亭 岳钦艳 GAO Baoyu HE Hongtao YU Hui SUN Shenglei LI Qian WANG Yan ZHAO Yu | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，6： | 7 |
| 5 | Complete genome analysis of Ketogulonigenium sp. WB0104显示文摘Ketogulonigenium sp. may convert L-sorbose into 2-keto-L-gulonic acid, the vitamin C precursor. The genome of Ketogulonigenium sp. WB0104 consists of a circular 2765030 bp chromo- some with 61.69% G+C content and two circular plasmids of 267968 and 242707 bp. The genome contains 2727 open reading frames (ORFs). The systems of replication, transcription, translation, carbohydrate and energy metabolism are intact, but the repair system is incomplete. About 640 predicted ORFs have been found to encode transporter pro- teins, which account for about one fourth of total predicted ORFs, noticeably higher than other docu- mented bacteria. This may be due to the fact that WB0104 adapts to soil circumstance. | YANG Fan JIA Qian XIONG Zhaohui ZHANG Xiaobing WU Hongtao ZHAO Ying YANG Jian ZHU Junping DONG Jie XUE Ying SUN Lilian SHEN Yan JIN Qi | 2006 | Chinese Science Bulletin2006，51，8： | 6 |

| 7 | Comparison of rumen bacteria distribution in original rumen digesta, rumen liquid and solid fractions in lactating Holstein cows显示文摘Background: Original rumen digesta, rumen liquid and solid fractions have been frequently used to assess the rumen bacterial community. However, bacterial profiles in rumen original digesta, liquid and solid fractions vary from each other and need to be better established.Methods: To compare bacterial profiles in each fraction, samples of rumen digesta from six cows fed either a high fiber diet(HFD) or a high energy diet(HED) were collected via rumen fistulas. Rumen digesta was then squeezed through four layers of cheesecloth to separate liquid and solid fractions. The bacterial profiles of rumen original digesta, liquid and solid fractions were analyzed with High-throughput sequencing technique.Results: Rumen bacterial diversity was mainly affected by diet and individual cow(P > 0.05) rather than rumen fraction. Bias distributed bacteria were observed in solid and liquid fractions of rumen content using Venn diagram and LEf Se analysis. Fifteen out of 16 detected biomarkers(using LEf Se analysis) were found in liquid fraction, and these 15 biomarkers contributed the most to the bacterial differences among rumen content fractions.Conclusions: Similar results were found when using samples of original rumen digesta, rumen liquid or solid fractions to assess diversity of rumen bacteria; however, more attention should be draw onto bias distributed bacteria in different ruminal fractions, especially when liquid fraction has been used as a representative sample for rumen bacterial study. | Shoukun Ji Hongtao Zhang Hui Yan Arash Azarfar Haitao Shi Gibson Alugongo Shengli Li Zhijun Cao Yajing Wang | 2017 | Journal of Animal Science and Biotechnology2017，8，3： | 4 |

| 9 | Identification of proteinaceous binding media for the polychrome terracotta army of Emperor Qin Shihuang by MALDI-TOF-MS显示文摘A proteinaceous binding media for the polychrome terracotta army of Emperor Qin Shihuang has been identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS).Methods for the preparation of the model samples and the elimination of interferences have been evaluated,as well as ageing processes.A method involving the complexation of EDTA in combination with dialysis was used to eliminate any interference in the polychrome layers taken from the historical samples.The model samples were aged by being buried in loess to replicate the ageing process of the historical samples as closely as possible.The optimum conditions for the extraction and subsequent enzymatic hydrolysis of the extracted protein were investigated.Under the optimized conditions,the‘‘peptide mass fingerprints’’of the proteinaceous binding media from the historical and model samples were determined by MALDITOF-MS.The results revealed that animal glue was used as the binding media for the polychrome layers of Emperor Qin Shihuang’s terracotta army.It also shows that animal glue used as binding media has a long history in China. | Hongtao Yan Jingjing An Tie Zhou Yin Xia Bo Rong | 2014 | Chinese Science Bulletin2014，59，21： | 3 |

| 11 | Analysis of proteinaceous binding media used in Tang Dynasty polychrome pottery by MALDI-TOF-MS显示文摘The proteinaceous binding media used in Tang Dynasty polychrome pottery was determined using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). The optimum conditions for the extraction and subsequent enzymatic hydrolysis of the protein sample were established, and applied to the pretreatment of model and historical samples. Complexation of EDTA in combination with dialysis was determined to be the most effective method for eliminating interferences in polychrome layers taken from historical samples. Model samples were aged by burial in loess so as to more closely replicate the ageing process of the historical samples. Using the aforementioned optimized conditions, the 'peptide mass fingerprint' of the binding media of historical and model samples was determined by MALDI-TOF-MS. Comparisons between the 'peptide mass fingerprint' obtained for the historical sample and those of the model samples proved that animal glue was used as the binding media for the Tang Dynasty polychrome pottery. It also shows that animal glue used as binding media enjoys a long history in China. | YAN HongTao AN JingJing ZHOU Tie LI YuHu | 2013 | Chinese Science Bulletin2013，58，24： | 3 |
| 12 | Selective Introduction of Carbazole and Diphenylamine into Spirofluorenexanthene Core for Different Phosphorescent Hosts显示文摘Built on the spiro[fluorene-9,9'-xanthene] (SFX) core and two frequently-used hole-transporting groups such ascarbazole and diphenylamine, two SFX derivatives, namely SFXCz and SFXDPA, have been synthesized byone-step reaction for red, green and blue phosphorescent organic light-emitting devices (PHOLEDs). Though theproperties of these two groups are very similar, the devices based on SFXCz and SFXDPA exhibit distinct perfor-mances. In blue PHOLEDs, the device based on SFXCz exhibited much better performances than that based onSFXDPA. However, the latter was superior to the former in green and red PHOLEDs. And the red PHOLED basedon SFXDPA exhibited maximum current efficiency (CE) of 27.1 cdoA^-l, power efficiency (PE) of 25.01m·W^-1, andexternal quantum efficiency (EQE) of 15.0%. The results show that the introduction of diphenylamine group issuitable for constructing green and red host materials, whereas the introduction of carbazole group is suitable forconstructing blue host materials. | Mingli Sun Shouzhen Yue Hongtao Cao Changjin Ou Yan Qian Ting Wang Ligang Chen Yi Zhao Wei Huang | 2016 | Chinese Journal of Chemistry2016，34，8： | 3 |
| 13 | Prompt Electrodeposition of Ni Nanodots on Ni Foam to Construct a High-Performance Water-Splitting Electrode:Efficient, Scalable,and Recyclable显示文摘In past decades,Ni-based catalytic materials and electrodes have been intensively explored as low-cost hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)catalysts for water splitting.With increasing demands for Ni worldwide,simplifying the fabrication process,increasing Ni recycling,and reducing waste are tangible sustainability goals.Here,binder-free,heteroatom-free,and recyclable Ni-based bifunctional catalytic electrodes were fabricated via a one-step quick electrodeposition method.Typically,active Ni nanodot(NiND)clusters are electrodeposited on Ni foam(NF)in Ni(NO3)2 acetonitrile solution.After drying in air,NiO/NiND composites are obtained,leading to a binder-free and heteroatom-free NiO/NiNDs@NF catalytic electrode.The electrode shows high efficiency and long-term stability for catalyzing hydrogen and oxygen evolution reactions at low overpotentials(10ηHER= 119 mV and 50ηOER=360 mV)and can promote water catalysis at 1.70 V@ 10mA cm-2.More importantly,the recovery of raw materials(NF and Ni(NO3)2)is quite easy because of the solubility of NiO/NiNDs composites in acid solution for recycling the electrodes.Additionally,a large-sized(S^70 cm2)NiO/NiNDs@NF catalytic electrode with high durability has also been constructed.This method provides a simple and fast technology to construct high-performance,low-cost,and environmentally friendly Ni-based bifunctional electrocatalytic electrodes for water splitting. | Hongtao Yu Ting Quan Shilin Mei Zdravko Kochovski Wei Huang Hong Meng Yan Lu | 2019 | Nano-Micro Letters2019，11，3： | 2 |
| 14 | Fabrication of quantum-sized Cd S-coated Ti O2 nanotube array with efficient photoelectrochemical performance using modified successive ionic layer absorption and reaction(SILAR) method显示文摘Quantum-sized Cd S-coated Ti O2 nanotube array(Q-Cd S-Ti O2NTA) was fabricated by the modified successive ionic layer absorption and reaction method.Scanning electron microscope and transmission electron microscope images showed the regular structure of Ti O2 NTA, where quantum-sized Cd S(diameter \10 nm)deposited on both the inside and outside of Ti O2 nanotube wall. Fabrication conditions including immersing cycles,calcination temperature and drying process were well optimized, and the Q-Cd S-Ti O2 NTA and its photoelectrochemical(PEC) properties were characterized by X-ray fluorescence spectrometer, UV–Vis diffuse reflectance spectra and photovoltage. Distinct increases in visible light absorption and photocurrent were observed as the immersing cycle was increased from 5 to 20 times. The additional drying process accelerated the Cd S crystal growth rate, and thus, the fabrication time could be shortened accordingly. Calcination temperature influenced the PEC property of Q-Cd S-Ti O2 NTA deeply, and the optimized calcination temperature was found as 500 °C. As the Q-Cd S-Ti O2 NTA was fabricated under such condition, thevisible photocurrent density increased to 2.8 m A/cm and the photovoltage between 350 and 480 nm was enhanced by 2.33 times than that without calcination. This study is expected to optimize Q-Cd S-Ti O2 NTA fabrication conditions for the purpose of improving its PEC performance. | Na Lu Yan Su Jingyuan Li Hongtao Yu Xie Quan | 2015 | Science Bulletin2015，60，14： | 2 |
| 15 | InSe/hBN/graphite heterostructure for high-performance 2D electronics and flexible electronics显示文摘Two-dimensional(2D)materials as channel materials provide a promising alternative route for future electronics and flexible electronics,but the device performance is affected by the quality of interface between the 2D-material channel and the gate dielectric.Here we demonstrate an indium selenide(lnSe)/hexagonal boron nitride(hBN)/graphite heterostructure as a 2D field-effect transistor(FET),with InSe as channel material,hBN as dielectric,and graphite as gate.The fabricated FETs feature high electron mobility up to 1,146 cm2·V^-1·s^-1 at room temperature and on/off ratio up to 1010 due to the atomically flat gate dielectric.Integrated digital inverters based on InSe/hBN/graphite heterostructures are constructed by local gating modulation and an ultrahigh voltage gain up to 93.4 is obtained.Taking advantages of the mechanical flexibility of these materials,we integrated the heterostructured InSe FET on a flexible substrate,exhibiting little modification of device performance at a high strain level of up to 2%.Such high-performance heterostructured device configuration based on 2D materials provides a new way for future electronics and flexible electronics. | Liangmei Wu Jinan Shi Zhang Zhou Jiahao Yan Aiwei Wang Ce Bian Jiajun Ma Ruisong Ma Hongtao Liu Jiancui Chen Yuan Huang Wu Zhou Lihong Bao Min Ouyang Sokrates T.Pantelides Hong-Jun Gao | 2020 | Nano Research2020，13，4： | 1 |
