| 1 | Aeration optimization through operation at low dissolved oxygen concentrations:Evaluation of oxygen mass transfer dynamics in different activated sludge systems显示文摘In wastewater treatment plants(WWTPs)using the activated sludge process,two methods are widely used to improve aeration efficiency — use of high-efficiency aeration devices and optimizing the aeration control strategy. Aeration efficiency is closely linked to sludge characteristics(such as concentrations of mixed liquor suspended solids(MLSS)and microbial communities)and operating conditions(such as air flow rate and operational dissolved oxygen(DO)concentrations). Moreover,operational DO is closely linked to effluent quality. This study,which is in reference to WWTP discharge class A Chinese standard effluent criteria,determined the growth kinetics parameters of nitrifiers at different DO levels in small-scale tests. Results showed that the activated sludge system could meet effluent criteria when DO was as low as 0.3 mg/L,and that nitrifier communities cultivated under low DO conditions had higher oxygen affinity than those cultivated under high DO conditions,as indicated by the oxygen half-saturation constant and nitrification ability. Based on nitrifier growth kinetics and on the oxygen mass transfer dynamic model(determined using different air flow rate(Q′_(air))and mixed liquor volatile suspended solids(MLVSS)values),theoretical analysis indicated limited potential for energy saving by improving aeration diffuser performance when the activated sludge system had low oxygen consumption; however,operating at low DO and low MLVSS could significantly reduce energy consumption. Finally,a control strategy coupling sludge retention time and MLVSS to minimize the DO level was discussed,which is critical to appropriate setting of the oxygen point and to the operation of low DO treatment technology. | Haitao Fan Lu Qi Guoqiang Liu Yuankai Zhang Qiang Fan Hongchen Wang | 2017 | Journal of Environmental Sciences2017,29,5: | 9 |
| 2 | Microbial diversity in cold seep sediments from the northern South China Sea显示文摘华南海(SCS ) 是最大的西方的和平的边缘的海。然而,微生物引起的研究从来没在寒冷被执行过渗出在 SCS 的沉积。在 2004, SONNE 177 巡航发现二冷渗出有在北 SCS 的不同的水深度的区域。在水深度在 3000 m 附近的地方, Haiyang 4 区域已经为在 seafloor 上的活跃渗出被证实了,例如微生物引起的地席, authigenic 碳酸盐外壳和瓣鳃类。我们在从这感冒收集的一个 5.55-m 沉积核心调查了微生物引起的丰富和差异渗出区域。一条综合途径包括地球化学和 16S rRNA 基因被采用种系发生的分析。这里,我们证明与沉积核心的地球化学侧面一起的微生物引起的丰富和差异揭示了在硫酸盐减小和甲烷氧化之间的 a coupled 反应。直接计数结果显示出的氮蒽橘子那微生物引起的丰富从 105 ~ 106 cells/g 沉积(湿重量)。丰富的深度相关的变化显示出象甲烷集中侧面的一样的趋势。种系发生的分析显示了减少硫酸盐的细菌和厌氧的氧化甲烷的 archaea 的存在。差异在表面是高得多的,但是处于沉积的 geochemical 条件响应变化与深度严厉地减少了,例如甲烷,硫酸盐集中和全部的器官的碳。海洋的 Benthic 组 B, Chloroflexi 和 JS1 分别地是 archaeal 和细菌的图书馆的占优势的 phylotypes。 | Yong Zhang Xin Su Fang Chen Yuanyuan Wang Lu Jiao Hailiang Dong Yongyang Huang Hongchen Jiang | 2012 | Geoscience Frontiers2012,3,3: | 9 |
| 3 | Microbial diversity in the hydrate-containing and-free surface sediments in the Shenhu area, South China Sea显示文摘Microbial diversity in the hydrate-containing(sites SH3B and SH7B)and-free(sites SH1B,SH5B,SH5C)sediments collected from the Shenhu area of the South China Sea(SCS)was investigated using 16S r RNA gene phylogenetic analysis.The phylogenetic results indicate difference in microbial communities between hydrate-containing and-free sediments.At the gas hydrate-containing sites,bacterial communities were dominated by Deltaproteobacteria(30.5%),and archaeal communities were dominated by Miscellaneous Crenarchaeotic Group(33.8%);In contrast,Planctomycetes was the major group(43.9%)in bacterial communities,while Marine Benthic Group-D(MBG-D)(32.4%)took up the largest proportion in the archaeal communities.Moreover,the microbial communities have characteristics different from those in other hydrate-related sediments around the world,indicating that the presence of hydrates can affect the microbial distribution.In addition,the microbial community composition in the studied sediments has its own uniqueness,which may result from co-effect of geochemical characteristics and presence/absence of hydrate. | Lu Jiao Xin Su Yuanyuan Wang Hongchen Jiang Yong Zhang Fang Chen | 2015 | Geoscience Frontiers2015,6,4: | 9 |
| 4 | Analysis of key microbial community during the start-up of anaerobic ammonium oxidation process with paddy soil as inoculated sludge显示文摘A sequencing batch reactor(SBR)-anaerobic ammonium oxidation(anammox) system was started up with the paddy soil as inoculated sludge. The key microbial community structure in the system along with the enrichment time was investigated by using molecular biology methods(e.g., high-throughput 16 S r RNA gene sequencing and quantitative PCR). Meanwhile,the influent and effluent water quality was continuously monitored during the whole start-up stage. The results showed that the microbial diversity decreased as the operation time initially and increased afterwards, and the microbial niches in the system were redistributed. The anammox bacterial community structure in the SBR-anammox system shifted during the enrichment, the most dominant anammox bacteria were Candidatus Jettenia. The maximum biomass of anammox bacteria achieved 1.68 × 10~9 copies/g dry sludge during the enrichment period, and the highest removal rate of TN achieved around 75%. | Xianglong Xu Guohua Liu Yuanyuan Wang Yuankai Zhang Hao Wan Lu Qi Hongchen Wang | 2018 | Journal of Environmental Sciences2018,30,2: | 8 |
| 5 | High-Temperature Metamorphism, Anataxis and Tectonic Evolution of a Mafic Granulite from the Eastern Himalayan Orogen显示文摘The Himalayan Orogen, resulting from the Tertiary collision of Indian and Asian continents, is a natural laboratory for studying metamorphism, partial melting and granite formation of collisional orogens. However, metamorphic and anatectic conditions and timescales of meta-mafic rocks in the Greater Himalayan Sequences(GHS) in the east-central Himalaya remain controversial. In this paper, we conduct a study of petrology and geochronology of mafic granulite from the Eastern Himalayan Syntaxis(EHS). The mafic granulite with abundant leucosome bands occurs as layers within felsic granulites and is well deformed. The granulite consists of garnet, plagioclase, amphibole and quartz with minor clinopyroxene, orthopyroxene, biotite, rutile, titanite and ilmenite. The garnet has growth compositional zoning and contains abundant mineral inclusions in its core. Peak metamorphic mineral assemblage of the granulite is garnet, amphibole, plagioclase, quartz, clinopyroxene and rutile, recording a high-pressure(HP) and high-temperature(HT) peak-metamorphism under conditions of 14–15.5 kbar and 780–790℃ in the presence of melt. The reconstructed clockwise P-T path is characterized by an early heating and burial prograde metamorphism, and late isothermal and cooling decompression retrogression. The granulite witnessed a long lasting HT metamorphism, partial melting and melt crystallization process which began at ca. 39 Ma and lasted to ca. 11 Ma. The present study shows that various high-grade rocks of the GHS in the EHS core experienced similar metamorphic conditions and P-T-t paths, indicating that they occurred as a coherent slab during the subduction and exhumation of Indian lithosphere. The significant melts generated during the prograde metamorphism of the GHS rocks not only contributed to the formation of the Himalayan leucogranite, but also resulted in the rheological weakening and ductile flow of the thickened lower crust of the Himalayan Orogen. | Zeming Zhang Huixia Ding Xin Dong Zuolin Tian Dongyan Kang Hongchen Mu Shengkai Qin Yuanyuan Jiang Mengmei Li | 2018 | Journal of Earth Science2018,29,5: | 7 |
| 6 | A 12-kyr record of microbial branched and isoprenoid tetraether index in Lake Qinghai,northeastern Qinghai-Tibet Plateau:Implications for paleoclimate reconstruction显示文摘Branched and Isoprenoid Tetraether(BIT) index was considered as a proxy for terrestrial organic matter input in lake sediments, based on the assumption that branched glycerol dialkyl glycerol tetraethers(b GDGTs) are mainly derived from terrestrial soils. However, mounting evidences have showed that the in situ production of b GDGTs is widespread in lakes, challenging BIT as a reliable terrestrial input proxy. Recently, BIT has been proven to be a reliable proxy for paleohydrology in a small crater lake(Lake Challa) in accordance with a different mechanism. However, the response of BIT to paleohydrology variation may differ for different lakes. In this study, we investigate the variations in the BIT index and the concentrations of its related GDGTs in a 12-ka sediment core from Lake Qinghai, in combination with our previous results for surface sediments. We find that variations in BIT strongly depend on the concentration of crenarchaeol in both surface and ancient sediments of this lake, whereas b GDGT concentration varies much less remarkably. Considering that crenarchaeol production is positively correlated with water depth in Lake Qinghai, water depth may exert negative control on the BIT index in this lake. This case is inconsistent with the positive relationship between BIT and lake levels or rainfall intensity reported for Lake Challa, suggesting that the response of BIT to local paleohydrology is site specific in lacustrine systems. Hence, the application of sedimentary BIT as a paleohydrological proxy in a specific lake requires caution before confirming the environmental controls on BIT in that lake. | WANG HuanYe DONG HaiLiang ZHANG ChuanLun JIANG HongChen LIU WeiGuo | 2016 | Science China Earth Sciences2016,59,5: | 6 |

| 8 | Osteogenic and antibacterial dual functions of a novel levofloxacin loaded mesoporous silica microspheres/nano-hydroxyapatite/ polyurethane composite scaffold显示文摘Lev/MSNs/n-HA/PU has been proved to be a novel scaffold material to treat bone defect caused by chronic osteomyelitis.We have previously identified that this material can effectively treat chronic osteomyelitis caused by Staphylococcus aureus in vivo.However,the potential mechanisms of antibacterial and osteogenic induction properties remain unclear.Thus,for osteogenesis property,immunohistochemistry,PCR,and Western blot were performed to detect the expression of osteogenic markers.Furthermore,flow cytometry and TUNEL were applied to analyze MC3T3-E1 proliferation and apoptosis.For antibacterial property,the material was co-cultivated with bacteria,bacterial colony forming units was counted and the release time of the effective levofloxacin was assayed by agar disc-diffusion test.Moreover,scanning electron microscope was applied to observe adhesion of bacteria.In terms of osteogenic induction,we found BMSCs adherently grew more prominently on Lev/MSNs/n-HA/PU.Lev/MSNs/n-HA/PU also enhanced the expression of osteogenic markers including OCN and COL1a1,as well as effectively promoted the transition from G1 phase to G2 phase.Furthermore,Lev/MSNs/n-HA/PU could reduce apoptosis of MC3T3-E1.Besides,both Lev/MSNs/n-HA/PU and n-HA/PU materials could inhibit bacterial colonies,while Lev/MSNs/n-HA/PU possessed a stronger antibacterial activities,and lower bacterial adhesion than n-HA/PU.These results illustrated that Lev/MSNs/n-HA/PU composite scaffold possess favorable compatibility in vitro,which induce osteogenic differentiation of MSCs,promote proliferation and differentiation of MC3T3-E1,and inhibit apoptosis.Moreover,clear in vitro antibacterial effect of Lev/MSNs/n-HA/PU was also observed.In summary,this study replenishes the potential of Lev/MSNs/n-HA/PU composite scaffold possess dual functions of anti-infection and enhanced osteogenesis for future clinical application. | Zhiping Kuang Guangming Dai Ruijie Wan Dongli Zhang Chen Zhao Cheng Chen Jidong Li Hongchen Gu Wei Huang | 2021 | Genes & Diseases2021,8,2: | 4 |

| 13 | Identification and characterization of soybean dreg soluble dietary fibre by combination of extrusion pre-treatment and enzymatic modification显示文摘OBJECTIVES:Soybean dreg is a by-product of soy milk processing,which contains high levels of soluble dietary fibre(SDF).In this study,we aimed to provide comprehensive processes of pre-treated extrusion for the improving structure and properties of soybean dreg soluble dietary fibre(SDSDF),which would be a valuable approach to enhance physiological activity.METHODS:Here,we characteristic the functional role of SDSDF employing to extrusion pretreatment.Soybean dregs were pre-treated using the twin screw extrusion method followed by enzymatic modification using neutral protease,α-amylase,glucoamylase,and cellulose to produce SDSDF.The physical properties and antioxidant activity of SDSDF were investigated.RESULTS:The morphology and crystal structure of SDSDF were observed that,through extrusion processing and enzymatic modification,the SDSDF yield increased by 106.28%.Moreover,the surface structure showed block-shaped or reticular formations in the extruded SDSDF,and the size of block-shaped cells was about 10μm.Infrared spectroscopic analysis showed that a characteristic absorption peak of polysaccharide appeared at 1631 cm−1 during extrusion processing.However,after extrusion processing,decreased absorption peaks were observed for the extruded SDSDF.Furthermore,XRD analysis showed that the 2θdiffraction peak changed at 24.16°for the extruded SDSDF.CONCLUSIONS:The overall findings suggest that the water holding capacity(WHC),oil holding capacity(OHC),expansibility,and the water solubility were significantly decreased in extruded SDSDF.In addition,the scavenging ability of 1,1-diphenyl-2-picrylhydrazyl(DPPH),-OH,O_(2)^(-),and the total reducing power were significantly improved,indicating that beneficial changes had taken place in the crystal structure of cellulose or hemicellulose to improve the physiological activity in extruded SDSDF. | Min Qu Yujia Liu Guang Zhang Sophia Jun Xue Hongchen Fan Yan Wang Shiyou Yu | 2017 | Food Quality and Safety2017,1,2: | 3 |
| 14 | A Correntropy-based Affine Iterative Closest Point Algorithm for Robust Point Set Registration显示文摘The iterative closest point(ICP)algorithm has the advantages of high accuracy and fast speed for point set registration,but it performs poorly when the point set has a large number of noisy outliers.To solve this problem,we propose a new affine registration algorithm based on correntropy which works well in the affine registration of point sets with outliers.Firstly,we substitute the traditional measure of least squares with a maximum correntropy criterion to build a new registration model,which can avoid the influence of outliers.To maximize the objective function,we then propose a robust affine ICP algorithm.At each iteration of this new algorithm,we set up the index mapping of two point sets according to the known transformation,and then compute the closed-form solution of the new transformation according to the known index mapping.Similar to the traditional ICP algorithm,our algorithm converges to a local maximum monotonously for any given initial value.Finally,the robustness and high efficiency of affine ICP algorithm based on correntropy are demonstrated by 2D and 3D point set registration experiments. | Hongchen Chen Xie Zhang Shaoyi Du Zongze Wu Nanning Zheng | 2019 | IEEE/CAA Journal of Automatica Sinica2019,6,4: | 3 |
| 15 | Methane formation route in the conversion of methanol to hydrocarbons显示文摘The influence factors and paths of methane formation during methanol to hydrocarbons(MTH) reaction were studied experimentally and thermodynamically. The fixed-bed reaction results show that the formation of methane was favored by not only high temperature, but also high feed velocity, low pressure, as well as weak acid sites dominated on deactivated catalyst. The thermodynamic analysis results indicate that methane would be formed via the decomposition reactions of methanol and DME, and the hydrogenolysis reactions of methanol and DME. The decomposition reactions are thermal chemistry processes and easily occurred at high temperature. However, they are influenced by catalyst and reaction conditions through DME intermediate. By contrast, the hydrogenolysis reactions belong to catalytic processes. Parallel experiments suggest that, in real MTH reactions, the hydrogenolysis reactions should be mainly enabled by surface active H atom which might come from hydrogen transfer reactions such as aromatization. But H2will be involved if the catalyst has active components like NiO. | Wenping Zhao Baozhu Zhang Guiru Wang Hongchen Guo | 2014 | Journal of Energy Chemistry2014,23,2: | 3 |

| 18 | A critical review of mineral–microbe interaction and co-evolution:mechanisms and applications显示文摘Mineral–microbe interactions play important roles in environmental change,biogeochemical cycling of elements and formation of ore deposits.Minerals provide both beneficial(physical and chemical protection,nutrients,and energy)and detrimental(toxic substances and oxidative pressure)effects to microbes,resulting in mineral-specific microbial colonization.Microbes impact dissolution,transformation and precipitation of minerals through their activity,resulting in either genetically controlled or metabolism-induced biomineralization.Through these interactions,minerals and microbes co-evolve through Earth history.Mineral–microbe interactions typically occur at microscopic scale but the effect is often manifested at global scale.Despite advances achieved through decades of research,major questions remain.Four areas are identified for future research:integrating mineral and microbial ecology,establishing mineral biosignatures,linking laboratory mechanistic investigation to field observation,and manipulating mineral–microbe interactions for the benefit of humankind. | Hailiang Dong Liuqin Huang Linduo Zhao Qiang Zeng Xiaolei Liu Yizhi Sheng Liang Shi Geng Wu Hongchen Jiang Fangru Li Li Zhang Dongyi Guo Gaoyuan Li Weiguo Hou Hongyu Chen | 2022 | National Science Review2022,9,10: | 2 |
| 19 | Sustained local delivery of insulin for potential improvement of peri-implant bone formation in diabetes显示文摘Dental implantation is an effective standard treatment modality to restore missing teeth and maxillofacial defects. However, in diabetics there is an increased risk for implant failure due to impaired peri-implant osseous healing. Early topical insulin treat- ment was recently shown to normalize diabetic bone healing by rectifying impairments in osteoblastic activities. In this study, insulin/poly(lactic-co-glycolic acid) (PLGA) microspheres were prepared by a double-emulsion solvent evaporation method. Microspheres were then incorporated in fibrin gel to develop a local drug delivery system for diabetic patients requiring im- plant treatment. In vitro release of insulin from fibrin gel loaded with these microspheres was assessed, and sustained prolonged insulin release over 21 days ascertained. To assess the bioactivity of released insulin and determine whether slow release might improve impaired diabetic bone formation, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), alkaline phosphatase (ALP) activity, mineralized nodule formation, and ELISA (enzyme-linked immunosorbent assay) assays were performed. The insulin released from the drug delivery system stimulated cell growth in previously inhibited cells, and ameliorated the impaired bone-forming ability of human MG-63 cells under high glucose conditions. Fibrin gel loaded with insulin/PLGA microspheres shows potential for improving peri-implant bone formation in diabetic patients. | HAN Yong ZHANG XueYan E LingLing WANG DongSheng LIU HongChen | 2012 | Science China(Life Sciences)2012,55,11: | 2 |
