| 1 | Treatment of oilfield produced water by anaerobic process coupled with micro-electrolysis显示文摘Treatment of oilfield produced water was investigated using an anaerobic process coupled with micro-electrolysis (ME),focusing on changes in chemical oxygen demand (COD) and biodegradability.Results showed that COD exhibited an abnormal change in the single anaerobic system in which it increased within the first 168 hr,but then decreased to 222 mg/L after 360 hr.The biological oxygen demand (five-day) (BOD5)/COD ratio of the water increased from 0.05 to 0.15.Hydrocarbons in the wastewater,such as pectin,degraded to small molecules during the hydrolytic acidification process.Comparatively,the effect of ME was also investigated.The COD underwent a slight decrease and the BOD5/COD ratio of the water improved from 0.05 to 0.17 after ME.Removal of COD was 38.3% under the idealized ME conditions (pH 6.0),using iron and active carbon (80 and 40 g/L,respectively).Coupling the anaerobic process with ME accelerated the COD removal ratio (average removal was 53.3%).Gas chromatography/mass spectrometry was used to analyze organic species conversion.This integrated system appeared to be a useful option for the treatment of water produced in oilfields. | Gang Li Shuhai Guo Fengmei Li | 2010 | Journal of Environmental Sciences2010，22，12： | 24 |

| 4 | Rare earth elements and carbon isotope geochemistry of the Doushantuo Formation in South China:Implication for middle Ediacaran shallow marine redox conditions显示文摘The middle Ediacaran Shuram excursion, the largest negative δ 13 C carb excursion in Earth history, has been interpreted as indirect evidence for episodic oxidation and remineralization of deep ocean DOC (dissolved organic carbon). It has been hypothesized that such oxidation event may have occurred when anoxic DOC-laden deep water was brought to shallow shelves during oceanic upwelling, which is expected to cause localized anoxia in shallow environments. To test this prediction, we systematically analyzed rare earth elements (REE) and δ 13 C carb of the upper Doushantuo Formation carbonates in the Yangtze Gorges area of South China, which were deposited in an inner shelf environment and record a large negative δ 13 C carb excursion correlated to the Shuram event. The REE data show a significant positive shift in Ce/Ce* values, synchronous with a pronounced negative δ 13 C carb shift. This positive Ce/Ce* shift is interpreted to represent an oceanic anoxia event in shallow shelf environments, which may have been caused by the upwelling or impingement of oxygen-depleted and 12 C-enriched deep water onto shelves. This anoxia event coincides with a sharp decline in the abundance and diversity of Ediacaran acanthomorphic acritarchs, raising the possibility that these two geobiological events may be causally related. | ZHOU ChuanMing JIANG ShaoYong XIAO ShuHai CHEN Zhe YUAN XunLai | 2012 | Chinese Science Bulletin2012，57，16： | 11 |

| 6 | An assessment of the effectiveness and impact of electrokinetic remediation for pyrene-contaminated soil显示文摘The effectiveness of electrokinetic remediation for pyrene-contaminated soil was investigated by an anode–cathode separated system using a salt bridge. The applied constant voltage was24 V and the electrode gap was 24 cm. Two types of soil(sandy soil and loam soil) were selected because of their different conductive capabilities. The initial concentrations of pyrene in these soil samples were 261.3 mg/kg sandy soil and 259.8 mg/kg loam soil. After treatment of the sandy soil and loam soil for seven days, 56.8% and 20.1% of the pyrene had been removed respectively. Under the same power supply voltage, the removal of the pollutant from the sandy soil was greater than that from the loam soil, due to the higher current and lower p H. Further analysis revealed that the effectiveness of electrokinetic remediation was affected by the energy expenditure, and was associated with changes in soil properties. | Sujuan Xu Shuhai Guo Bo Wu Fengmei Li Tingting Li | 2014 | Journal of Environmental Sciences2014，26，11： | 11 |
| 7 | Toughening mechanism of lined Al_2O_3-ZrO_2 multiphaseceramics in SHS composite pipes显示文摘Hypoeutectic and hypereutectic Al2O3-ZrO2 multiphase ceramics-lined composite pipes were produced by using the gravita-tional separation self-propagate high-temperature synthesis (SHS) process. The microstructure of the ceramics was observed by meansof SEM and EPMA. The fracture toughness of the multiphase ceramics was tested by using the Vickers indentation method. Thefracture toughness of hypoeutectic Al2O3-ZrO2 multiphase ceramics is 15.96 MPa·m1/2 and that of hypoeutectic Al2O3-ZrO2 multiphaseceramics is 15.23 MPa·m1/2. The toughening mechanisms were systematically investigated by means of SEM and XRD. The resultsshow that the bridging toughening mechanism, stress induced ZrO2 transformation toughening mechanism, and microcrack tougheningmechanism are the predominant toughening mechanism. | Guibo Yu Wen Yan Shuhai Wang Baoxin Su Baolai Tan | 2006 | Journal of University of Science and Technology Beijing2006，13，2： | 11 |

| 9 | The Weng'an biota and the Ediacaran radiation of multicellular eukaryotes显示文摘The rise of multicellularity represents a major evolutionary transition and it occurred independently in multiple eukaryote clades.Although simple multicellular organisms may have evolved in the Mesoproterozoic Era or even earlier,complex multicellular eukaryotes began to diversify only in the Ediacaran Period,just before the Cambrian explosion.hus,the Ediacaran fossil record can provide key paleontological evidence about the early radiation of multicellular eukaryotes that ultimately culminated in the Cambrian explosion.he Ediacaran Weng’an biota in South China hosts exceptionally preserved eukaryote fossils,including various acanthomorphic acritarchs,pseudoparenchymatous thalli,tubular microfossils,and spheroidal fossils such as Megasphaera,Helicoforamina,Spiralicellula,and Caveasphaera.Many of these fossils have been interpreted as multicellular eukaryotes,although alternative interpretations have also been proposed.In this review,we critically examine these various interpretations,focusing particularly on Megasphaera,which has been variously interpreted as a sulfur-oxidizing bacterium,a unicellular protist,a mesomycetozoean-like holozoan,a volvocine green alga,a stem-group animal,or a crown-group animal.We conclude that Megasphaera is a multicellular eukaryote with evidence for cell-to-cell adhesion,a lexible membrane unconstrained by a rigid cell wall,spatial cellular diferentiation,germ–soma separation,and programmed cell death.hese features are inconsistent with the bacterium,unicellular protist,and mesomycetozoean-like holozoan interpretations.hus,the surviving hypotheses,particularly the stem-group animal and algal interpretations,should be further tested with additional evidence.he Weng’an biota also hosts cellularly diferentiated pseudoparenchymatous thalli with specialized reproductive structures indicative of an ainity with lorideophyte red algae.he other Weng’an fossils reviewed here may also be multicellular eukaryotes,although direct cellular evidence is lacking in some and phylogenetic ainities are poorly constrained in others.he Weng’an biota ofers many research opportunities to resolve the life histories and phylogenetic diversity of early multicellular eukaryotes and to illuminate the evolutionary prelude to the Cambrian explosion. | Shuhai Xiao A.D.Muscente Lei Chen Chuanming Zhou James D.Schiffbauer Andrew D.Wood Nicholas F.Polys Xunlai Yuan | 2014 | National Science Review2014，1，4： | 9 |
| 10 | New observations on spicule-like structures from Dou-shantuo phosphorites at Weng'an,Guizhou Province显示文摘Doushantuo phosphorites at Weng’an, Guizhou Province, provide a unique opportunity for the study of early evolution of multicellular organisms, including metazoans. Our light microscope and SEM observations, however, do not substantiate a sponge spicule interpretation of spicular structures. No convincing axial canals have been seen in the observed spicule population. Instead, the coexistence of some monaxonal spicules with clearly diagenetic crystal fascicles and dumbbells suggest that these monaxons may also be diagenetic in origin. Our preliminary EDS analyses detect no significant silicon in spicule-containing intraclasts (including abiotic clasts and fragments of sphaeromorphic acritarchs and algal thalli), that contain abundant monaxonal spicular structures. We, therefore, believe that the evidence for a sponge spicule interpretation of the Doushantuo spicular structures are at best ambiguous at present; these alleged sponge spicules are indistinguishable from coexistent diagenetic crystals. | Leiming Yin Shuhai Xiao Xunlai Yuan | 2001 | Chinese Science Bulletin2001，46，21： | 8 |
| 11 | Water Quality Evaluation in Tidal River Reaches of Liaohe River Estuary, China Using a Revised QUAL2K Model显示文摘Rivers in the Liaohe River Estuary area have been seriously polluted by discharges of wastewater containing petroleum pol- lutants and nutrients. In this paper, The Enhanced Stream Water Quality Model (QUAL2K) and its revised model as well as One-dimensional Tide Mean Model (1D model) were applied to predict and assess the water quality of the tidal river reach of the Liaohe River Estuary. Dissolved oxygen (DO), biochemical oxygen demand (BOD5), ammonia nitrogen (NH3-N) and total phosphorus (TP) were chosen as water quality indices in the two model simulations. The modelled results show that the major reasons for degraded rivers remain petroleum and non-point source pollution. Tidal water also has a critical effect on the variation of water quality. The sensitivity analysis identifies that flow rate, point load and diffuse load are the most sensitive parameters for the four water quality indices in the revised QUAL2K simulation. Uncertainty analysis based on a Monte Carlo simulation gives the probability distribution of the four water quality indices at two locations (6.50 km and 44.84 km from the river mouth). The statistical outcomes indicate that the observed data fall within the 90% confidence intervals at all sites measured, and show that the revised QUAL2K gives better results in simulating the water quality of a tidal river. | YE Hanfeng GUO Shuhai LI Fengmei LI Gang | 2013 | Chinese Geographical Science2013，23，3： | 7 |
| 12 | New Bivalved Arthropods from the Cambrian(Series 3, Drumian Stage) of Western Hunan, South China显示文摘We report two new three-dimensionally phosphatized microfossils, Cambrolongispina reticulata gen. et sp. nov. and Cambrolongispina glabra gen. et sp. nov., from the middle Cambrian(Series 3, Drumian Stage) at Wangcun, Yongshun County, western Hunan, South China. They are bivalved arthropods, with thin, pliable, originally chitinous or chitin-calcareous shields(c. 350–517μm long). The shields are equipped with a pair of antero-dorsal spines. The spines are internally hollow, varying in length from 1/2 of to as long as the shield length in C. reticulata, and uniformly longer than the shield length in C. glabra. The spines of C. reticulata are ornamented with a longitudinal row of conical or blade-shaped denticles along the posterior edge. Cambrolongispina lacks marginal rims, valve lobation and sulci which are diagnostic of the Bradoriida sensu stricto. It also lacks a doublure/duplicature characteristic of phosphatocopids and some bradoriids. It could be related to the Monasteriidae(which may belong to Bradoriida sensu lato), both characterized by a pair of antero-dorsal spines. Cambrolongispina may have been meiofaunal detritus feeders that lived on or within sediments. The antero-dorsal spines may have been sensory organs to detect nearby predators. The posterior denticles on these spines might have facilitated the sensory function of the spines. | ZHANG Huaqiao DONG Xi-ping XIAO Shuhai | 2014 | Acta Geologica Sinica(English Edition)2014，88，5： | 7 |
| 13 | A New Class of Harmonic Univalent Functions by the Generalized Salagean Operator显示文摘A complex-valued harmonic functions that are univa-lent and sense preserving in the unit disk U can be written in the form f = h + g, where h and g are analytic in U. We define and investigate a new class SHPλ (α , β )by generalized Salagean op-erator of harmonic univalent functions. We give sufficient coeffi-cient conditions for normalized harmonic functions in the class SHPλ (α , β ). These conditions are also shown to be necessary when the coefficients are negative. This leads to distortion bounds and extreme points. | LI Shuhai LIU Peide | 2007 | Wuhan University Journal of Natural Sciences2007，12，6： | 6 |
| 14 | A brief review on the convergence to steady state solutions of Euler equations with high-order WENO schemes显示文摘Weighted essentially non-oscillatory(WENO)schemes are a class of high-order shock capturing schemes which have been designed and applied to solve many fluid dynamics problems to study the detailed flow structures and their evolutions.However,like many other high-order shock capturing schemes,WENO schemes also suffer from the problem that it can not easily converge to a steady state solution if there is a strong shock wave.This is a long-standing difficulty for high-order shock capturing schemes.In recent years,this non-convergence problem has been studied extensively for WENO schemes.Numerical tests show that the key reason of the non-convergence to steady state is the slight post shock oscillations,which are at the small local truncation error level but prevent the residue to settle down to machine zero.Several strategies have been proposed to reduce these slight post shock oscillations,including the design of new smoothness indicators for the fifth-order WENO scheme,the development of a high-order weighted interpolation in the procedure of the local characteristic projection for WENO schemes of higher order of accuracy,and the design of a new type of WENO schemes.With these strategies,the convergence to steady states is improved significantly.Moreover,the strategies are applicable to other types of weighted schemes.In this paper,we give a brief review on the topic of convergence to steady state solutions for WENO schemes applied to Euler equations. | Shuhai Zhang Jun Zhu Chi-Wang Shu | 2019 | Advances in Aerodynamics2019，1，1： | 6 |
| 15 | Phosphatized biotas from the Neoproterozoic Doushantuo Formation on the Yangtze Platform显示文摘The Doushantuo Formation in South China was deposited after the Nantuo glaciation but before the evolution of complex Ediacaran metazoans. It contains multiple taphonomic windows, in its cherts, carbonaceous shales, and phosphorites, onto the late Neoproterozoic biosphere. The phosphatic window is unusually clear; Doushantuo phosphorites at Weng’an (Guizhou Province) are known to exquisitely preserve a multitude of single-celled eukaryotes, muiticellular algae, and microscopic animals. Our recent survey reveals that, in addition to the now famous Weng’an locality, Doushantuo phosphorites at Baokang (Hubei), Chadian (Shaanxi), and Shangrao (Jiangxi) also contain diverse eukaryotes preserved at the cellular level. All these phosphorites were deposited in shallow-water environments, typically above fair weather wave base and close to ancient islands. Along with Doushantuo cherts and shales, these phosphorites give us a clearer and more complete picture of late Neoproterozoic biological evolution: there | ZHOU Chuanming YUAN Xunlai XIAO Shuhai | 2002 | Chinese Science Bulletin2002，47，22： | 6 |

| 17 | Effect of electric intensity on the microbial degradation of petroleum pollutants in soil显示文摘Electro-bioremediation is an innovative method to remedy organic-polluted soil. However, the principle of electrokinetic technology enhancing the function of microbes, especially the relationship of electric intensity and biodegradation efficiency, is poorly investigated. Petroleum was employed as a target organic pollutant at a level of 50 g/kg (mass of petroleum/mass of dry soil). A direct current power supply was used for tests with a constant direct current electric voltage (1.0 V/cm). The petroleum concentrations were measured at 3275–3285 nm after extraction using hexane, the group composition of crude oil was analyzed by column chromatography. The water content of soil was kept 25% (m/m). The results indicated the degradation process was divided into two periods: from day 1 to day 40, from day 41 to day 100. The treatment of soil with an appropriate electric field led the bacteria to have a persistent effect in the whole period of 100 days. The highest biodegradation efficiency of 45.5% was obtained after treatment with electric current and bacteria. The electric-bioremediation had a positive effect on alkane degradation. The degradation rate of alkane was 1.6 times higher in the soil exposed to electric current than that treated with bacteria for 100 days. A proper direct current could stimulate the microbial activities and accelerate the biodegradation of petroleum. There was a positive correlation between the electric intensities and the petroleum bioremediation efficiencies with a coefficient of 0.9599. | Tingting Li Shuhai Guo Bo Wu Fengmei Li Zhixin Niu | 2010 | Journal of Environmental Sciences2010，22，9： | 6 |
| 18 | A Fully Self-Healing Piezoelectric Nanogenerator for Self-Powered Pressure Sensing Electronic Skin显示文摘As an important way of converting mechanical energy into electric energy,a piezoelectric nanogenerator(PENG)has been widely applied in energy harvesting as well as self-powered sensors in recent years.However,its robustness and durability are still severely challenged by frequent and inevitable mechanical impacts in real application environments.Herein,a fully selfhealing PENG(FS-PENG)as a self-powered pressure sensing electronic skin is reported.The self-healing piezoelectric composite and self-healing Ag NW electrode fabricated through mixing piezoelectric PZT particles and conductive Ag NWs into self-healing polydimethylsiloxane(H-PDMS)are assembled into the sandwich structure FS-PENG.The FS-PENG could not only effectively convert external stimulation into electrical signals with a linear response to the pressure but also retain the excellent self-healing and stable sensing property after multiple cycles of cutting and self-healing process.Moreover,a self-healing pressure sensor array composed of 9 FS-PENGs was attached on the back of the human hand to mimic the human skin,and accurate monitoring of the spatial position distribution and magnitude of the pressure was successfully realized. | Maosen Yang Jinmei Liu Dong Liu Jingyi Jiao Nuanyang Cui Shuhai Liu Qi Xu Long Gu Yong Qin | 2021 | Research2021，，1： | 6 |
