| 1 | A CORRELATION EQUATION FOR CALCULATING INCLINED JET PENETRATION LENGTH IN A GAS-SOLID FLUIDIZED BED显示文摘Numerical simulation of gas-solid flow in a two-dimensional fluidized bed with an inclined jet was performed. The numerical model is based on the two-fluid model of gas and solids phase in which the solids constitutive equations are based on the kinetic theory of granular flow. The improved ICE algorithm, which can be used for both low and high-velocity fluid flow, were used to solve the model equations. The mechanism of jet formation was analyzed using both numerical simulations and experiments. The emergence and movement of gas bubbles were captured numerically and experimentally. The influences of jet velocity, nozzle diameter, nozzle inclination and jet position on jet penetration length were obtained. A semi-empirical expression was derived and the parameters were correlated from experimental data. The correlation equation, which can be easily used to obtain the inclined jet penetration length, was compared with our experimental data and published correlation equations. | Ruoyu Hong Haibing Li Jianmin Ding Hongzhong Li | 2005 | China Particuology2005，3，5： | 3 |
| 2 | Geochemical characteristics of hadal sediment in the northern Yap Trench显示文摘Two sediment cores were retrieved in the hadal zone of the Yap Trench,and their concentrations of six major elements Mg,Al,Ca,Ti,Mn and Fe and nine trace elements Sr,Ba,Pb,V,Cr,Co,Ni,Cu and Zn were determined in inductively coupled plasma atomic emission spectrometry(ICP-AES).According to the vertical distribution profiles of the 15 elements,the correlation of their concentrations,the ratios of Ni/Co,V/Cr,Fe/Al,and Ti/Al,and morphological characteristics of the sediment samples,the implications of the depositional environment and the sediment provenance were analyzed.The results show that the ratio of Ni/Co in all depths of the two sediment cores were below 5,and the ratio of V/Cr were lower than 2,indicating that the depositional environment of the hadal zone in the trench was oxidative and might have inflow of the Antarctic bottom oxygen-rich water.The sediment samples on the eastern side of the trench were siliceous mud mainly composed of diatoms,radiolarian,and sponge needles from surface to deep layer.The vertical profile of the elements,the concentration of TOC and the fossil record indicated that the sediment sample from station Dive113 was well mixed from surface to bottom layer.Based on the correlation of concentrations of the elements,the morphological characteristics of the sediment,and the ratios of Fe/Al and Ti/Al,we inferred that the sediment in the hadal zone of the trench had terrestrial,volcanic,biological,and authigenic sources.Major source of the sediment in the eastern side of the trench were terrestrial;whereas the sediment in the western side of the trench received more volcaniclastic input. | HUANG Yuhuan SUN Chengjun YANG Guipeng YUE Xin’an JIANG Fenghua CAO Wei YIN Xiaofei GUO Chaonan NIU Jiaohong DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 3 |
| 3 | Towards the understanding from sea surface to hadal zone—A multidisciplinary study of the Yap Trench显示文摘The water column in the open ocean can be divided into epipelagic(photic),mesopelagic,bathyal,abyssal and hadal zones by depth.In recent years,more and more research has been focusing on the marine environment below photic zone,especially the deep ocean.Oceanic trenches are considered as the deepest part of the ocean,providing ideal places for studying the physical,chemical,biological,and geological aspects of the marine environment from sea surface to the deep sea fl oor.However,limited by the high diffi culty to access and high cost in exploration,our understanding about oceanic trenches is still limited.Recently,with the development of series of manned and unmanned submersibles,we now have more opportunities to study the trench area. | DING Haibing SUN Chengjun | 2020 | Journal of Oceanology and Limnology2020，38，3： | 2 |
| 4 | Distribution characteristics of lipids in hadal sediment in the Yap Trench显示文摘In this study,cored sediment samples collected by the Jiaolong Submersible at 6779 m depth from the hadal zone of the Yap Trench in May 2016 were sliced in 1-cm interval from top to bottom,and lipids in each sediment layer were quantitatively and qualitatively analyzed.The vertical distribution profiles of the lipids in the sediment sample,their main existing forms,and their possible sources were investigated.The results show that the concentration of lipid in the surface sediment was the highest with the carbon number from 12 to 27,dominated by medium and short-chain lipids.The total concentration of fatty acids in surface sediment was much higher than those in the offshore and deep-sea areas,being up to 325.77μg/g due to the funnel effect caused by the“V”terrain of the trench.Fatty acid 18:0 was the most abundant lipids in the sediment sample.Abnormal high concentrations of fatty acid 18:1ω7 and alkanes indicated the existence of hydrothermal fluids in the study area.In addition,saturated fatty acids and monounsaturated fatty acids existed mainly in free form,and polyunsaturated fatty acids existed mainly in bound form.Most of the alkanes were in bound form,and their major source was autochthounous input.The carbon number of alcohols in the sediment sample ranged from 12 to 20,mainly existed in bound form.The source of fatty acids was mainly autochthonous input,and the neutral lipids had both marine and terrestrial origin.This is the first study of lipids in hadal sediment of the Yap Trench.The results will promote deeper understanding of organic carbon cycle in marine environment. | YAN Yixin SUN Chengjun HUANG Yuhuan CAO Wei JIANG Fenghua YANG Guipeng DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 2 |
| 5 | The study of the adductor muscle-shell interface structure in three Mollusc species显示文摘The adductor muscle scar(AMS) is the fixation point of adductor muscle to the shell. It is an important organicinorganic interface and stress distribution area. Despite recent advances, our understanding of the structure and composition of the AMS remain limited. Here, we report study on the AMS of three bivalves: Mytilus coruscus,Chlamys farreri and Ruditapes philippinarum. Results showed that there were significant differences among their AMS structures. Both M. coruscus and C. farreri were found to have a columnar layer above the nacreous platelet shell structure at the AMS and this layer was more organized in M. coruscus. There was no distinguishable twolayer structure in R. philippinarum. Atomic force microscopy(AFM) and Fourier transform infrared spectroscopy(FT-IR) results showed that the AMS was much smoother than the nacreous inner shell in all the three species and the AMS had minor different compositions from the nacreous shell layer. SDS-PAGE(sodium dodecyl-sulfate polyacrylamide gel electophoresis) study of the proteins isolated from the interface indicated that there was a 70 k Da protein which seemed to be specifically located to the highly organized columnar AMS structure in Mytilus coruscus. Further analysis of this protein showed it contained high level of Asx(Asp+Asn), Glx(Glu+Gln) and Gly.The special structure and composition of the AMS might play important roles in the stability, adhesion and function at this stress distribution site. | ZHU Yaoyao SUN Chengjun SONG Yingfei JIANG Fenghua YIN Xiaofei TANG Min DING Haibing | 2016 | Acta Oceanologica Sinica2016，35，8： | 1 |

| 9 | Vertical variations of dissolved carbohydrates in the North Yap Trench显示文摘The concentrations of dissolved monosaccharides(MCHO),polysaccharides(PCHO),and total carbohydrates(TCHO)in the seawater samples collected from the north of the Yap Trench in the western Pacific Ocean were measured by 2,4,6-tripyridine-s-triazine(TPTZ)spectrophotometry method.The results show that the concentrations of MCHO,PCHO,and TCHO ranged from 4.6 to 22.1μmol C/L,3.5 to 27.3μmol C/L,and 13.8 to 36.3μmol C/L,respectively.In different sampling stations,the concentrations of MCHO,PCHO,and TCHO with water depth showed complex variation patterns.In the study area,the maximum concentrations of MCHO,PCHO,and TCHO occurred in the euphotic layer and the minimum concentrations occurred in mesopelagic seawater layer.Generally,the concentrations of MCHO,PCHO,and TCHO decreased with water depth from the euphotic layer to the hadal zone.The average value of PCHO/TCHO was higher than the average value of MCHO/TCHO,indicating that PCHO was the main component of TCHO in north of the Yap Trench. | GUO Chaonan SUN Chengjun YANG Guipeng ZHANG Honghai CHEN Yan YIN Xiaofei JIANG Fenghua HUANG Yuhuan NIU Jiaohong DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 1 |
| 10 | Black phosphorus quantum dots as multifunctional nanozymes for tumor photothermal/catalytic synergistic therapy显示文摘Nanozymes are nanomaterials with enzyme-like properties that have attracted significant interest owing to their high stability,easy preparation,and tunable catalytic properties,especially in the field of cancer therapy.However,the unfavorable catalytic effects of nanozymes in the acidic tumor microenvironment have limited their applications.Herein,we developed a biomimetic erythrocyte membrane-camouflaged ultrasmall black phosphorus quantum dots(BPQDs)nanozymes that simultaneously exhibited an exceptional near-infrared(NIR)photothermal property and dramatically photothermal-enhanced glucose oxidase(GOx)-like activity in the acidic tumor microenvironment.We demonstrated the engineered BPQDs gave a photothermal conversion efficiency of 28.9%that could rapidly heat the tumor up to 50℃ while effectively localized into tumors via homing peptide iRGD leading after intravenously injection.Meanwhile,the significantly enhanced GOx-like activity of BPQDs under NIR irradiation was capable of catalytical generating massive toxic reactive oxygen species via using cellular glucose.By combining the intrinsic photothermal property and the unique photothermal-enhanced GOx-like catalytic activity,the developed BPQDs were demonstrated to be an effective therapeutic strategy for inhibiting tumor growth in vivo.We believe that this work will provide a novel perspective for the development of nanozymes in tumor catalytic therapy. | Hui Ding Daji Wang Haibing Huang Xiaozhu Chen Jie Wang Jinjie Sun Jianlin Zhang Lu Lu Beiping Miao Yanjuan Cai Kelong Fan Yongtian Lu Hongsong Dong Xiyun Yan Guohui Nie Minmin Liang | 2022 | Nano Research2022，15，2： | 1 |
| 11 | Maternal genetic structure of a neolithic population of the Yangshao culture显示文摘The Yangshao culture is one of the most influential Neolithic cultures in East Asia.The populations associated with the Yangshao culture were widely distributed along the Yellow River basin and were suggested to play a profound role in the present-day East Asians.To date,the population of the Yangshao culture is largely investigated through archaeological studies. | Bo Miao Yichen Liu Wanfa Gu Qingli Wei Qian Wu Wenjun Wang Ming Zhang Manyu Ding Tianyi Wang Juncen Liu Feng Liu Peng Cao Qingyan Dai Ruowei Yang Xiaotian Feng Wanjing Ping Weihong Hou Haibing Yuan Qiaomei Fu | 2021 | Journal of Genetics and Genomics2021，48，8： | 0 |
| 12 | Effect of normal and strict anaerobic fermentation on physicochemical quality and metabolomics of yogurt显示文摘Generally,yogurts on the market are usually anaerobic fermentation,but oxygen can be still dissolved in the production process,which is actually not strict anaerobic.This study explored the multiple quality indicators and the metabolomic analysis of yogurts fermented by Lactobacillus bulgaricus and Streptococcus thermophilus using two fermentation methods,namely,strict anaerobic and normal fermentation.The changes in flavor substances in yogurts,including 17 free amino acids,17 fatty acids,and 7 response value,were detected using principal component and multi factor analyses.Based on the results of the comparisons between basic physical and chemical indicators,strict anaerobic fermentation increased the growth and acidification of the two bacteria,the response value of sourness,umami and richness.Strict anaerobic fermentation increased the free amino acid(Fold change=1.53)and short chain fatty acid levels(Fold change=1.73),and reduced the polyunsaturated fatty acid(Fold change=0.51)levels.Furthermore,metabolomic analysis based on UPLC-Triple TOF-MS/MS showed that 92 differential metabolites were screened;45 differential metabolites were increased and 47 were decreased.The results revealed that strict anaerobic fermentation was beneficial to metabolic changes and nutritional indicators of yogurt,which may be as indicators of valuable reference to improve dairy fermentation process. | Ruixue Ding Mohan Li Yiting Zou Yiran Wang Chunyue Yan Haibing Zhang Rina Wu Junrui Wu | 2022 | Food Bioscience2022，46，2： | 0 |

| 14 | Vertical variations and composition of dissolved free amino acid in the seawater of the Yap Trench in the western Pacific Ocean显示文摘The composition and concentration of dissolved free amino acid(DFAA)of seawater samples collected in May 2016 from the surface to the hadal zone of the northern region of the Yap Trench were analyzed by pre-column derivatization of o-phthalaldehyde.Results show that the average concentration of DFAA in the study area was 0.47±0.36μmol/L.In different sampling stations,the concentrations of DFAA with water depth showed complex variation patterns.At the sediment-seawater interface,the concentrations of DFAA in the western side of the trench were obviously higher than that in its eastern side.In the study area,there were no significant correlations between the concentrations of DFAA and the environmental parameters such as concentrations of chlorophyll a(Chl a),dissolved oxygen(DO),pH,and dissolved inorganic nitrogen(DIN),indicating that the concentrations of DFAA in seawater of the trench are affected by many factors,such as photosynthesis,respiration,temperature,pressure,illumination,and circulation.The dominant DFAA are similar in different water layers of sampling stations,including aspartic acid(Asp),glutamic acid(Glu),glycine(Gly),and serine(Ser).The composition of different amino acids,and the relative abundance of acidic,basic,and neutral amino acids might be related to the sources and consumption of various amino acids.Nine pairs of amino acids in the DFAA showed significantly positive relationship by correlation matrix analysis,suggesting that they might share similar biogeochemical processes.The degradation index(DI)of the DFAA in seawater of the Yap Trench could reflect the degradation,source,and freshness of DFAA in the trench to some extents.This is a preliminary study of amino acids from sea surface to hadal zone in the ocean,more works shall be done in different trenches to reveal their biogeochemical characte ristics in extreme marine environme nts. | Jiaohong NIU Chengjun SUN Bo YANG Lei XIE Fenghua JIANG Wei CAO Yan CHEN Haibing DING Yuhuan HUANG Xianchi GAO | 2023 | Journal of Oceanology and Limnology2023，41，1： | 0 |
| 15 | Rapid and sensitive detection of Epstein-Barr virus antibodies in nasopharyngeal carcinoma by chemiluminescence strips based on iron-porphyrin single atom nanozyme显示文摘The correlation between Epstein-Barr virus(EBV)infection and nasopharyngeal carcinoma(NPC)risk has been extensively researched.The continual monitoring of EBV-IgAs provides a promising approach of NPC screening in its early stage.In this study,we successfully synthesized a single-atom nanozyme(SANzyme)through the application of iron-porphyrin based metal organic framework(MOF-FeP).The MOF-FeP possesses precisely-defined electronic and geometric structures that accurately mimic highly-evolved catalytic site of natural peroxidase.The peroxidase-like activity of MOF-FeP enables it to catalyze the chemiluminescence of luminol substrate.By integrating MOF-FeP into a traditional strip,we created a rapid and highly-sensitive evaluation tool for detecting EBV-IgAs.Importantly,the MOF-FeP strip enables the simultaneous detection of three EBV-IgAs,greatly improving the accuracy of EBV-associated NPC screening.The sensitivities of the MOF-FeP strip(75.56%–93.30%)surpass those of current enzyme-linked immunosorbent assay(ELISA)methods(64.44%–82.22%).This test takes only 16 min to perform as opposed to the customary 1–2 h required for standard ELISA.Additionally,the MOF-FeP strip is suitable for whole blood samples,thereby significantly simplifying the sample preparation and detection process.In conclusion,the MOF-FeP strip combines the simplicity of traditional strip with the high catalytic activity of SANzyme.Our innovative MOF-FeP strip offers a new point-of-care strategy for EBV-IgAs detection,which is expected to markedly facilitate early screening for EBV-associated diseases. | Daji Wang Jie Wang Dan Liu Jiuyang He Meiying Wang Haibing Huang Guohui Nie Hui Ding Xiyun Yan | 2024 | Nano Research2024，17，3： | 0 |
| 16 | Characteristics of Vertical Distributions of Fatty Acids in Surface Sediments of the Yellow Sea and East China Sea显示文摘Fatty acids(FAs) in sediment collected from three different stations in the Yellow Sea and the East China Sea were analyzed for their distributions and to determine evidence of harmful algal blooms in the sediment core.Less diverse FAs were found in the Yellow Sea(YS) station,whereas in the two stations of the East China Sea(ECS) the FAs were more diverse.Concentrations of some FA species in the two ECS stations displayed an occasional surge in their vertical profile.The highest concentration of FAs was found in the surface layer of station QT3(43.28 μg g^(-1)).Monounsaturated FAs were more susceptible to degradation compared to their saturated counterparts,and changes of 16:0,18:2 and 20:5 accounted for the most variability in total concentrations of FAs as those species made up most of the quantified FAs.The origins of the major fraction of FAs were attributed to autotrophic sources,and bacterial FAs accounted for only a small fraction of the total FAs in the region.Nutrient availability was a possible regulating factor controlling bacteria abundances in marine sediments in the ECS and the YS.A principal component analysis(PCA) was applied to analyze the FA dataset and to reveal the principal environmental factors that control the composition of FAs in the sediments.PC2,which explains 15% of the variance,was estimated to reflect the diagenetic effects on the FA compositional changes in sediments influenced by bacterial degradation. | LOPES Evanildo O.

| 17 | Characteristics of vertical distributions of methane and dimethylsulphoniopropionate in the southern Yap Trench显示文摘Methane(CH_(4) )and dimethylsulphoniopropionate(DMSP)are major carbon and sulfur sources for bacterioplankton in the ocean.We investigated the characteristics of CH_(4) and DMSP in the southern Yap Trench from sea surface to hadal zone in June 2017.We found that concentrations of CH_(4) varied from 1.5 to 4.5 nmol/L with saturation between 94% and 204% in the euphotic layer.Concentrations of dissolved DMSP(DMSPd)ranged from 0.5 to 3.7 nmol/L with higher values in surface water and decreased with depth.Concentrations of particulate DMSP(DMSPp)varied from 0 to 13.6 nmol/L.Concentrations of total DMSP(DMSPt)ranged 2.0-15.2 nmol/L.Their concentrations decreased slightly and reached consistent levels in 200-3000-m depth due probably to heterotrophic bacterial production in marine aphotic and high-pressure environments.An exception occurred around 4000-m depth where their concentrations increased considerably and then decreased in deeper water.This previously unrecognized phenomenon sheds light on the elevated concentrations of DMSP in the abyssal layer that might be affected by the Lower Circumpolar Deep Water(LCPW).Concentrations of CH_(4) in seawater of the Benthic Boundary Layer of the southern Yap Trench were slightly higher than those in the water column at approximate depth,and concentrations of DMSP in seawater of the Benthic Boundary Layer of the southern Yap Trench were not much higher than those in the water column at the approximate depth,indicating that sediment was a weak source of CH_(4) but was not a source of DMSP for seawater in the study area.This study presented clear correlations between CH_(4) and DMSP from sea surface to sea bottom,proving that DMSP might be a potential substrate for CH_(4) not only in oxic surface seawater but also in deep water. | Yuhuan HUANG Chengjun SUN Lina Lü Neal Xiangyu DING Liangmin YU Guipeng YANG Haibing DING | 2023 | Journal of Oceanology and Limnology2023，41，6： | 0 |
| 18 | Characteristics of dissolved sugars in the Southern Yap Trench from sea surface to hadal zone显示文摘2,4,6-Tripyridine-s-triazine(TPTZ)spectrophotometric method was applied to determine the concentrations of dissolved monosaccharides(MCHO),polysaccharides(PCHO),and total carbohydrate(TCHO)in seawater samples collected from sea surface to hadal zone and sediment-seawater interface of the Southern Yap Trench in the Western Pacific Ocean.Results show that the concentrations of MCHO,PCHO,and TCHO ranged from 6.3 to 22.3μmol C/L,1.1 to 25.4μmol C/L,and 12.1 to 44.9μmol C/L,respectively,from the euphotic layer to the hadal zone of the trench.At different sampling stations,the concentrations of MCHO,PCHO,and TCHO in the seawater showed complex vertical variation characteristics,but the overall variation trends were decreasing with water depth.In the Southern Yap Trench,the maximum concentration of MCHO in the seawater appeared in the euphotic layer,and the minimum in the hadal zone.The maximum concentration of PCHO appeared in the euphotic layer,and the minimum in the bathypelagic layer.The water layer where the maxima and minima of the average concentration of TCHO appeared was consistent with that of PCHO.PCHO was the major component of TCHO in the seawater of the Southern Yap Trench.In the seawater from the sediment-seawater interface,the concentrations of MCHO,PCHO,and TCHO ranged from 8.4 to 10.6μmol C/L,3.8 to 5.8μmol C/L,and 12.2 to 15.2μmol C/L,respectively,and MCHO was the major component of TCHO.The key factors affecting the concentration and existing forms of dissolved sugars in the seawater of the Southern Yap Trench included photosynthesis,respiration,polysaccharide hydrolysis,adsorption and desorption of particulate matter,trench“funnel effect”,deep ocean currents,sediment resuspension,and etc.This study provided fundamental data about labile organic matter in abyss and hadal zone of marine environment,which is significant for further understanding of deep-sea organic carbon cycle. | Dong CUI Chengjun SUN Chaonan GUO Wei CAO Fenghua JIANG Haibing DING | 2023 | Journal of Oceanology and Limnology2023，41，6： | 0 |
