| 1 | Grouting techniques for the unfavorable geological conditions of Xiang'an subsea tunnel in China显示文摘One of the major challenges during subsea tunnel construction is to seal the potential water inflow.The paper presents a case study of Xiang'an subsea tunnel in Xiamen,the first subsea tunnel in China.During its construction,different grades of weathered geomaterials were encountered,which was the challenging issue for this project.To deal with these unfavorable geological conditions,grouting was adopted as an important measure for ground treatment.The grouting mechanism is first illustrated by introducing a typical grouting process.Then the site-specific grouting techniques employed in the Xiang'an subsea tunnel are elaborated.By using this ground reinforcement technique,the tunneling safety of the Xiang'an subsea tunnel was guaranteed. | Dingli Zhang Qian Fang Haicheng Lou | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014，6，5： | 12 |
| 2 | Study on enzymatic hydrolysis of soybean β-conglycinin using alkaline protease from Bacillus subtilis ACCC 01746 and antigenicity of its hydrolysates显示文摘Due to its beneficial health effects,the use of soybean protein has shown a continuous increase,but concerns regarding the allergenicity of soybean antigenic protein have also increased.This study aimed to evaluate the hydrolytic effects of a non-commercial alkaline protease isolated from the Bacillus subtilis ACCC 01746 on soybeanβ-conglycinin and the allergenicity of its hydrolysates.Alkaline protease of the strain was separated by precipitation method of organic solvents,and theβ-conglycinin was separated by alkali-solution and acid-isolation and purified by use of gel column.Using the degree of hydrolysis(DH)and inhibition rate as evaluation indexes,the enzymatic hydrolysis parameters ofβ-conglycinin was optimized by single factor and L_(9)(3^(4))orthogonal tests,so as to explore the effect of the protease on the hydrolysis degree and the antigenicity ofβ-conglycinin hydrolysates.The results showed that the native enzyme existed as an 18.3 kDa monomer with a 430 U/g maximum activity.The purity ofβ-conglycinin was 84.8%.The single-factor test results showed that DH showed the oppostie trendency with the inhibition rate,and the increase of protein concentration causedmonotone increasing and monotone decreasing of the inhibition rate and the DH,and the optimal protein concentration was 30 mg/mL.The optimization results showed that pH had the largest impacts on both DH and the inhibition rate,followed by enzyme dosage,hydrolysis temperature and hydrolysis time.Under the optimum hydrolysis conditions of protein concentration 30mg/mL,enzymedosage0.7%,hydrolysis time40min,temperature 55°C and pH8.5,the DH reached the highest of 76.28%,and the inhibition rate was the lowest of 27.03%,which was reduced greatly compared with that before optimization.These results suggested that alkaline protease appeared to show a relatively high effeciency in lowering soybean allergenicity,making it possible to produce low-allergenicity soybean protein. | Haicheng Yin Xinrui Zhang Jin Huang | 2021 | Grain & Oil Science and Technology2021，4，1： | 6 |
| 3 | Study on Isolation and Raman Spectroscopy of Glycinin in Soybean Protein显示文摘The secondary structures of soybean glycinin was investigated by Raman spectroscopy and its acidic and basic polypeptides were isolated. The results showed that the secondary structures of glycinin were mainly composed of 21.51% α-helix, 41.62% β-sheet,24.70% β-turn, and 12.18% random coil. For the disulfide bridge(—S—S—), the ratios were 34.8% gauche—gauche—gauche(g—g—g), 32.1% gauche—gauche—trans(g—g—t), and 33.1% trans-gauche-trans(t—g—t). The I_(850)/I_(830) intensity ratio of glycinin Raman tyrosine doublet confirmed that the contents of the N-buried and N-exposed tyrosine residue were 14.1% and 85.9%,respectively. The typical acidic subunit A and basic subunit B were clearly separated by heat denaturation and reduction withβ-mercaptoethanol, and their corresponding molecular masses were 42 and 38 ku, respectively. Raman spectroscopic analysis can be used to determine the secondary structural properties of glycinin. Further studies of the glycinin structures will be helpful for the utilization of soybean protein resources. | YIN Haicheng HUANG Jin ZHANG Huiru | 2018 | Grain & Oil Science and Technology2018，1，2： | 5 |
| 4 | Effect of extrusion on the structure and antigenicity of soybean β-conglycinin显示文摘β-Conglycinin,the main component of 7S globulin in soybean protein,is also a key soybean antigen protein that causes allergic reactions.Extrusion technologies have received considerable attention as amethod for modifying soybean protein allergens.This study investigated the changes inβ-conglycinin structure and antigenicity upon extrusion.Isoelectric precipitation,ammoniumsulfate precipitation,and sepharose CL-6B gel filtration were used to isolate and purifyβ-conglycinin from soybean powder,and single-factor and orthogonal tests were used to study the effects of water content,extrusion temperature,screw rotation speed,and feeding speed on the antigenicity ofβ-conglycinin after extrusion.Fourier transforminfrared spectrometry(FTIR)was then employed to analyze the structure ofβ-conglycinin after extrusion under the optimal conditions determined by the orthogonal test.The results showed that extrusion significantly reduced the antigenicity ofβ-conglycinin(P<0.05),and the degree of influence of the factors studied may be ordered as extrusion temperature>feeding speed>screw rotation speed>water content.The optimal parameters were temperature at 130°C,screwrotation speed at 140 r/min,and feeding speed at 35 g/min.Under these conditions,the contents ofα-helix,β-pleated sheet,andβ-turn structures inβ-conglycinin were significantly reduced(P<0.05),while the contents of random coils were significantly increased(P<0.05).The peak absorption intensity of amides I,II,and III also decreased.Taken together,the findings suggest that extrusion could be an effective method for reducing the antigenicity ofβ-conglycinin. | Haicheng Yin Feng Jia Jin Huang Yong Zhang Xin Zheng Xinrui Zhang | 2019 | Grain & Oil Science and Technology2019，2，3： | 5 |
| 5 | Soil erosion affects variations of soil organic carbon and soil respiration along a slope in Northeast China显示文摘Background:Although soil erosion plays a key role in the carbon cycle,a holistic and mechanistic understanding of the soil erosion process within the cycle is still lacking.The aim of this study was therefore to improve our mechanistic understanding of soil organic carbon(SOC)and soil respiration dynamics through an experiment conducted in an eroding black soil farmland landscape in Northeast China.Results:The depositional profiles store 5.9 times more SOC than the eroding profiles and 3.3 times more SOC than the non-eroding profiles.A linear correlation between the SOC and 137Cs(Caesium-137)was observed in our study,suggesting that the SOC decreased with increased soil erosion.Furthermore,the fractions of intermediate C and the microaggregate C were lowest at the eroding position and highest at the depositional position.In the depositional topsoil,the input of labile materials plays a promotional role in soil respiration.Conversely,in the subsoil(i.e.,below 10 cm),the potential mineralization rates were lowest at the depositional position—due to effective stabilization by physical protection within soil microaggregates.The field results of soil surface respiration also suggest that the depositional topsoil SOC is prone to be mineralized and that SOC at this depositional context is stabilized at subsoil depth.In addition,the high water contents at the depositional position can limit the decomposition rates and stabilize the SOC at the same time.Conclusions:The findings from this study support that a majority of the SOC at footslope is stored within most of the soil profile(i.e.,below 10 cm)and submitted to long-term stabilization,and meanwhile support that the depositional profile emits more CO2 than the summit due to its high amount and quality of SOC. | Tong Li Haicheng Zhang Xiaoyuan Wang Shulan Cheng Huajun Fang Gang Liu Wenping Yuan | 2019 | Ecological Processes2019，8，1： | 4 |
| 6 | Protective Effect of Bacillus subtilis Peptidoglycan (PG) on β-conglycinin-induced Intestinal Epithelial Cells Damage of Juvenile Carp (Cyprinus carpio)显示文摘[Objective] The paper was to investigate the protective effects of different concentrations of Bacillus subtilis peptidoglycan(PG) on β-conglycinin-induced inflammatory injury in intestinal epithelial cells of juvenile carp(Cyprinus carpio).[Method] In 24-cell microplates, the intestinal epithelial cells(IECs) of juvenile carp were primarily cultured for 72 h at 26°C and 6% CO2, and then the IECs were randomly divided into6 groups with 4 replicates per group. One of the six groups was set as negative control group, and the other groups were all supplemented with 1.0 mg/mL β-conglycinin in culture medium to establish inflammatory injury. At 24 h post induction, the culture media were changed into B. subtilis PG culture media with the concentrations of 0(positive control group), 0.15, 0.30, 0.45 and 0.60 mg/mL, respectively. The samples were collected to measure the antioxidant and anti-inflammatory indices at 12, 24 and 36 h post culture.[Result]β-conglycinin exposure significantly decreased the activity of ASA, AHR, SOD, CAT, GPx, and increased the PC content and the mRNA expression of inflammatory cytokines(IL-1β, IL-8, TNF-α1,IL-10 and TGF-β). At 12, 24 and 36 h post PG treatment, the activities of ASA, AHR, SOD, CAT, GPx and the content of PC in cells decreased in a dose-dependent manner;the mRNA levels of IL-1β, IL-8 and TNF-α1 were down-regulated and those of IL-10 and TGF-β were up-regulated.[Conclusion] Different concentrations of B. subtilis PG could protect IECs oxidative damage induced by β-conglycinin and improve the antioxidant capacity of IECs. High concentration of PG could improve the anti-inflammatory ability of IECs by inhibiting inflammatory factors and promoting the gene expression of anti-inflammatory cytokines. | Zhang Tiantian Yin Haicheng Huang Wei | 2019 | Animal Husbandry and Feed Science2019，11，2： | 3 |
| 7 | Optical and scintillation properties of Bi_4Si_3O_(12):RE(RE=Eu^(3+), Sm^(3+),Ho^(3+), Tb^(3+))single crystals显示文摘Bi_4 Si_3 O_(12):RE(BSO:RE, RE = Eu^(3+), Sm^(3+), Ho^(3+), Tb^(3+)) crystals were grown by the modified vertical Bridgeman method, and doping effects on scintillation properties were investigated. Under γ-ray irradiation, the light yield of BSO doped with small doses of Eu^(3+) increases slightly, and the energy resolution improves significantly compared to pure BSO, therefore the ability of distinguishing between particles will be improved for BSO crystals with a small amount of Eu^(3+) dopant. The results show that a small amount of Eu^(3+) doping can sensitize the Bi^(3+) ions. The sensitization effect enables the reduction of intrinsic defects, and thus improves the scintillation properties. However, the relative light yield of BSO:Tb(1.0 mol%) crystal is 4.3%, which is smaller than 5.0% of pure BSO. The improved light yield and energy resolution in the BSO:Eu and BSO:Sm crystals are considered an impressive achievement in the optimization of this scintillator which is already suitable for applications such as dual-readout calorimeters and homogeneous hadron calorimeters. | Xuefeng Xiao Jiayue Xu Haicheng Wei Yaoqing Chu Bobo Yang Xuefeng Zhang | 2019 | Journal of Rare Earths2019，37，3： | 2 |
| 8 | The regulatory network behind maize seed germination: Effects of temperature, water, phytohormones, and nutrients显示文摘Seed germination is the process by which an organism grows from a seed. It requires suitable conditions and environmental factors. Maize is one of the most important crops worldwide. Germination influences both final maize yield and quality. Seed germination is regulated by a complex gene network. It is also influenced by endogenous(phytohormones and nutrients) and exogenous(temperature and water)inputs, involving molecular networks only partly identified to date. This review describes current understanding of the influence of temperature, water, phytohormones, and nutrients in regulating maize seed germination, and indicates knowledge gaps that should be addressed. | Xiaofei Xue Shangyi Du Fuchao Jiao Menghan Xi Aiguo Wang Haicheng Xu Qiqing Jiao Xin Zhang Hao Jiang Jingtang Chen Ming Wang | 2021 | The Crop Journal2021，9，4： | 2 |
| 9 | Recent advances in wave energy converters based on nonlinear stiffness mechanisms显示文摘Wave energy is one of the most abundant renewable clean energy sources,and has been widely studied because of its advantages of continuity and low seasonal variation.However,its low capture efficiency and narrow capture frequency bandwidth are still technical bottlenecks that restrict the commercial application of wave energy converters(WECs).In recent years,using a nonlinear stiffness mechanism(NSM)for passive control has provided a new way to solve these technical bottlenecks.This literature review focuses on the research performed on the use of nonlinear mechanisms in wave energy device utilization,including the conceptual design of a mechanism,hydrodynamic models,dynamic characteristics,response mechanisms,and some examples of experimental verification.Finally,future research directions are discussed and recommended. | Xiantao ZHANG Haicheng ZHANG Xiao ZHOU Ze SUN | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，7： | 2 |
| 10 | Microstructure and mechanical properties of railway wheels manufactured with low-medium carbon Si-Mn-Mo-V steel显示文摘The suitability of carbide-free bainite steel as railway wheel materials was investigated. The low-medium carbon Si-Mn-Mo-V steel was designed to make railway wheels by forging and rolling. The slack quenching with water was conducted on the tread of rim section by programmed control to simulate isothermal heat treatment after being austenitized. Microstructures and mechanical properties have been studied. The results indicate that the microstructure of the rim is mainly carbide-free bainite, and the mixed microstructure of bainitic ferrite and granular bainite is observed in web and hub. The mechanical properties are superior to both the standard requirements and the commercial production, such as CL60 plain carbon. The Charpy impact energy is relatively high at room and/or subzero temperatures. The force-displacement curves and fractographies reveal the excellent ability of resistance to crack initiation and propagation. | Mingru Zhang Haicheng Gu | 2008 | Journal of University of Science and Technology Beijing2008，15，2： | 2 |

| 13 | Enzymatic kinetics ofβ-conglycinin using alkaline protease from Bacillus subtilis ACCC 01746 and analysis of antigenicity of hydrolyzed peptide显示文摘β-Conglycinin,the main protein of soybean,is a key allergen that causes soybean allergies,and hydrolysis is usually applied to lower its antigenicity.We evaluated the enzymolysis characters ofβ-conglycinin from the perspective of enzymolysis kinetics using alkaline protease from B.subtilis ACCC 01746.A dynamic model describing the hydrolysis ofβ-conglycinin was proposed using the initial substrate concentration,enzyme dosage(enzyme to substrate ratio)and hydrolysis time as variables to illustrate the kinetic behavior of enzymatic hydrolysis.The hydrolysis of soybeanβ-conglycinin was carried out at 60 g/L protein concentration,0.6%enzyme dosage,55℃ and pH 8.5 to observe the peptides with anti-enzymatic activities.The hydrolysates were gradually fractionated by ultrafiltration through cut-off membranes with molecular weights of 40,30,20,and 10 kDa,and their antigenicities were evaluated using indirect competitive enzyme-linked immunosorbent assay.The results showed that the degree of hydrolysis(DH)ofβ-conglycinin decreased as theβ-conglycinin concentration(S0)increased,but increased with enzyme dosage(E0)increasing.Thus,the enzymatic hydrolysis ofβ-conglycinin followed the first-order kinetics model.The hydrolysis rate(V)was(527.89C_(E0)-2.5533C_(S0))exp(-0.022DH),the DH-hydrolysis time was 45.454ln[1+(11.614C_(E0)/C_(S0)-0.0562)t],and the correlated kinetic constants k2 and kd were 527.89 min^(−1)and 8.6126 min^(−1),respectively.The hydrolysis behavior ofβ-conglycinin varied considerably among theα',α,andβsubunits.Faster hydrolysis rates were observed for theα'andαsubunits compared to theβsubunit.The relative molecular weights of the intercepted peptides from the hydrolysates were 14.8-40.1 kDa,and the antigenicity of the peptides with smaller molecular weight was reduced,but not removed completely.However,the alkaline protease from the strain appeared to effectively reduce the allergenicity ofβ-conglycinin.Therefore,it is possible to produce less allergenic soybean proteins using enzymatic hydrolysis.Additionally,the microbial alkaline protease may serve as a potential novel food enzyme and should be evaluated for the development of hypoallergenic foods. | Haicheng Yin Xinrui Zhang Zhixiang Yang Jin Huang | 2021 | Grain & Oil Science and Technology2021，4，3： | 1 |

| 15 | Enabling dendrite-free charging for lithium batteries based on transport-reaction competition mechanism in CHAIN framework显示文摘Worldwide trends in mobile electrification will skyrocket demands for lithium-based battery production,driven by the popularity of electric vehicles.However,both lithium metal batteries and lithium ion batteries face severe safety issues due to dendrite nucleation and growth process.Li deposition is significantly influenced by interfacial factors and charging conditions.In this paper,an electrochemical model considering the internal and external factors is proposed based on Monte Carlo method.The influence of internal solid electrolyte interphase(SEI)porosity,thickness and the external conditions on dendrite growth process is systematically described.The simulation results support that the three factors investigated in this model could synergistically regulate the dendrite growth process.Three competition mechanisms are proposed to tailor lithium deposition for Li-based batteries and numerical solutions for variation pattern of dendrite growth with time are fitted.A three-step process describing kinetic process of lithium deposition is proposed.To achieve dendrite-free charging process,charging strategies and emerging materials design should be considered,including physicochemical materials engineering,artificial SEI,and design for dynamic safety boundary.This work could contribute to the foundation for insights of Li deposition mechanism,which is promising to provide guidelines for next-generation high-energy-density and safe batteries in CHAIN framework. | Lisheng Zhang Siyan Chen Wentao Wang Hanqing Yu Haicheng Xie Huizhi Wang Shichun Yang Cheng Zhang Xinhua Liu | 2022 | Journal of Energy Chemistry2022，，12： | 1 |

| 18 | Validation of novel hub genes and molecular mechanisms in acute lung injury using an integrative bioinformatics approach显示文摘Acute lung injury(ALI)is an inflammatory pulmonary disease that can easily develop into serious acute respiratory distress syndrome,which has high morbidity and mortality.However,the molecular mechanism of ALI remains unclear,and few molecular biomarkers for diagnosis and treatment have been identified.In this study,we aimed to identify novel molecular biomarkers using a bioinformatics approach.Gene expression data were obtained from the Gene Expression Omnibus database,co-expressed differentially expressed genes(CoDEGs)were identified using R software,and further functional enrichment analyses were conducted using the online tool Database for Annotation,Visualization,and Integrated Discovery.A protein-protein interaction network was established using the STRING database and Cytoscape software.Lipopolysaccharide(LPS)-induced ALI mouse model was constructed and verified.The hub genes were screened and validated in vivo.The transcription factors(TFs)and miRNAs associated with the hub genes were predicted using the NetworkAnalyst database.In total,71 CoDEGs were screened and found to be mainly involved in the cytokine-cytokine receptor interactions,and the tumor necrosis factor and malaria signaling pathways.Animal experiments showed that the lung injury score,bronchoalveolar lavage fluid protein concentration,and wet-to-dry weight ratio were higher in the LPS group than those in the control group.Real-time polymerase chain reaction analysis indicated that most of the hub genes such as colony-stimulating factor 2(Csf2)were overexpressed in the LPS group.A total of 20 TFs including nuclear respiratory factor 1(NRF1)and two miRNAs were predicted to be regulators of the hub genes.In summary,Csf2 may serve as a novel diagnostic and therapeutic target for ALI.NRF1 and mmu-mir-122-5p may be key regulators in the development of ALI. | Qingchun Liang Qin Zhou Jinhe Li Zhugui Chen Zhihao Zhang Ruimeng Liu Haicheng Huang Zhiyong Peng Youtan Liu | 2021 | Acta Biochimica et Biophysica Sinica2021，53，3： | 1 |
| 19 | Characterization of CANON reactor performance and microbial community shifts with elevated COD/N ratios under a continuous aeration mode显示文摘The effects of increasing COD/N on nitrogen removal performance and microbial structure were investigated in a SBR adopting a completely autotrophic nitrogen removal over nitrite process with a continuous aeration mode (DO at approximately 0.15-0.2 mg/L). As the COD/N increased from 0.1 to W0.59, the nitrogen removal efficiency QMRE) increased from 88.7% to 95.5%;while at COD/N ratios of 0.59-0.82, the NRE remained at 90.7%-95.5%. As the COD/N increased from 0.82 to 1.07, the NRE decreased continuously until reaching 60.1%. Nitrosomonas sp.(AOB) and Candidatus Jet tenia (anammox bacteria) were the main functional genera in the SBR. As the COD/N increased from 0.10 to 1.07, the relative abundance of Nitrosomonas decreased from 13.4% to 2.0%, while that of Candidatus Jettenia decreased from 35% to 9.9% with COD/N < 0.82 then increased to 45.4% at a COD/N of 1.07. Aerobic heterotrophic bacteria outcompeted AOB at high COD loadings (650 mg/L) because of oxygen competition, which ultimately led to deteriorated nitrogen removal pertormance. | Yao Zhang Yayi Wang Yuan Yan Haicheng Han Min Wu | 2019 | Frontiers of Environmental Science & Engineering2019，13，1： | 1 |
| 20 | Fungal spore record of pastoralism on the NE Qinghai-Tibetan Plateau since the middle Holocene显示文摘Pastoralism is considered a crucial factor in the eventual year-round occupation of high-altitude regions(>3000 m asl)of the Qinghai-Tibetan Plateau,and the northeastern Qinghai-Tibetan Plateau(NE-QTP)was an important corridor for early human occupation.We analyzed fossil fungal spore records for the last 8500 years from a high resolution aeolian section at Langgeri(LGR)on the NE-QTP.Thirty-two fungal spore types were identified in the LGR section,including seven coprophilous types.We combined analysis of coprophilous fungal spores,Cyperaceae,Artemisia,and Hippophae pollen,and the charcoal>50µm fraction to explore the timing and controls of pastoralism on the NE-QTP since the middle Holocene.Pastoralism commenced at LGR shortly before ca.5.5 ka and gradually increased between ca.5.5–3.5 ka,but markedly intensified after ca.2.2 ka,with three periods of growth at ca.2.1–1.9,1.4–1.2,and 0.6–0 ka,and a decline at ca.1.1–0.6 ka.The timing of changes in pastoral activity on the NE-QTP based on the coprophilous fungal spore record is supported by regional archeology and historical documents.Technological and political developments,rather than climate change,played key roles in the long-term fluctuations of regional pastoralism on the NE-QTP in the late Holocene. | Haicheng WEI Chongyi E Ronglei DUAN Jing ZHANG Yongjuan SUN Guangliang HOU Jingyi GAO | 2021 | Science China Earth Sciences2021，64，8： | 1 |
