| 1 | Changes of protein oxidation,lipid oxidation and lipolysis in Chinese dry sausage with different sodium chloride curing salt content显示文摘The effect of sodium chloride(NaCl)curing salt content on protein oxidation,lipid oxidation and lipolysis of Chinese dry sausage was investigated.Two groups Chinese dry sausages with 2%and 4%(m/m)salt content were studied.The degree of protein oxidation increased during the processes in two groups sausages,while the content of phospholipids decreased,neutral lipids and free fatty acids increased.The degree of protein oxidation,lipid oxidation and lipolysis in 4%NaCl content group was higher than those in 2%NaCl content group,while 4%NaCl content group has higher lipase activity.In conclusion,4%NaCl may facilitate the protein oxidation,lipid hydrolysis and oxidation in Chinese dry sausage,and the protein oxidation had strong correlation with lipid oxidation and lipolysis.The results could provide a basis for improving the technology of industrial production. | Bing Zhao Huimin Zhou Shunliang Zhang Xiaoqian Pan Su Li Ning Zhu Qianrong Wu Shouwei Wang Xiaoling Qiao Wenhua Chen | 2020 | Food Science and Human Wellness2020，9，4： | 22 |
| 2 | Overexpression of the Watermelon Ethylene Response Factor ClERF069 in Transgenic Tomato Resulted in Delayed Fruit Ripening显示文摘Watermelon fruit undergoes distinct development stages with dramatic changes during fruit ripening.To date,the molecular mechanics of watermelon ripening remain unclear.Genetic and transcriptome evidences suggested that the ethylene response factor(ERF)gene ClERF069 may be an important candidate factor affecting watermelon fruit ripening.To dissect the roles of ClERF069 in fruit ripening,structure and phylogenetic analysis were performed using the amplified full-length sequence.Normal-ripening watermelon 97103,non-ripening watermelon PI296341-FR and the RIL population were used to analyze ClERF069 expression dynamics and the correlation with fruit ripening indexs.The results indicated that ClERF069 belongs to ERF family group VI and show high homology(83%identity)to melon ERF069-like protein.ClERF069 expression in watermelon flesh was negatively correlated with fruit lycopene content and sugar content during fruit ripening progress.Further transgenic evidences indicated that overexpression of 35S:ClERF069 in tomato noticeably delayed the ripening process up to 5.2 days.Lycopene,β-carotenoid accumulation patterns were altered and ethylene production patterns in transgenic fruits was significantly delayed during fruit ripening.Taken together,watermelon ethylene response factor ClERF069 was concluded to be a negative regulator of fruit ripening. | Ming Zhou Shaogui Guo Shouwei Tian Jie Zhang Yi Ren Guoyi Gong Changbao Li Haiying Zhang Yong Xu | 2020 | Horticultural Plant Journal2020，6，4： | 9 |
| 3 | Synthesis of Z-scheme g-C3N4 nanosheets/Ag3PO4 photocatalysts with enhanced visible-light photocatalytic performance for the degradation of tetracycline and dye显示文摘Graphene-like C3N4/Ag3PO4 photocatalysts are synthesized by calcination and solutions precipitating method.The obtained g-C3N4/Ag3PO4 composites display excellent photocatalytic activity for the degradation of methylene orange(MO),rhodamine B(RhB)and tetracycline(TC)under visible light irradiation.The solutions containing RhB(10 mg/L)and MO(10 mg/L)can be efficiently degraded within15 min and 30 min.Especially,nearly 80%of TC(50 mg/L)is degraded within 20 min.which are much better than those of pure g-C3N4 nanosheets and Ag3PO4,implying that strong interaction and reasonable energy band alignment in the contact interface can effectively transfer the carries.Furthermore,the g-C3N4/Ag3PO4 composites exhibit the improved stability,and only a slight decrease is observed after three recycling runs.Moreover,the impact of inorganic ions and PH values on the degradation performance is rather small.The Z-scheme photocatalytic mechanism of the g-C3N4/Ag3PO4 composites based on the active species trapping experimental is proposed.This work demonstrates the promising applications of the g-C3N4/Ag3PO4 composites in environmental issues. | Meng Ding Juanjuan Zhou Hongcen Yang Ruya Cao Shouwei Zhang Minghui Shao Xijin Xu | 2020 | Chinese Chemical Letters2020，31，1： | 6 |
| 4 | Development of volatiles and odor-active compounds in Chinese dry sausage at different stages of process and storage显示文摘The effect of process and storage on the volatiles and odorant profi le of Chinese dry sausage was evaluated,as well as its physicochemical parameters.Microbial esterification and wine(27.54%–43.35%),and lipid oxidation(11.30%–34.92%)played a key role in flavor profile during process and storage.A significant increase of each volatile was detected during process except gradual decrease of volatiles from spices,while a gradual decrease of each volatile was detected during storage except signifi cant increase of volatiles from lipid oxidation and esterifi cation.15 and 6 odor-active compounds were respectively correlated(P<0.05)with the process and storage time.Level of heptanal,1-octen-3-ol,the ethyl of 2-methylbutanoic,3-methylbutanoic,butanoic,benzoic,hexanoic,heptanoic,octanoic and decanoic acid were best discriminators of process stage,while(E)-2-nonenal,ethyl hexanoate,ethyl heptanoate,and methyl decanoate,were marker compounds of storage time.An objective method was established to evaluate the stages of process and storage for samples. | Huimin Zhou Bing Zhao Shunliang Zhang Qianrong Wu Ning Zhu Su Li Xiaoqian Pan Shouwei Wang Xiaoling Qiao | 2021 | Food Science and Human Wellness2021，10，3： | 4 |

| 7 | Fundamental characteristics of gas hydrate-bearing sediments in the Shenhu area, South China Sea显示文摘The basic physical properties of marine natural gas hydrate deposits are important to the understanding of seabed growth conditions, occurrence regularity, and occurrence environment of natural gas hydrates. A comprehensive analysis of the core samples of drilling pressure-holding hydrate deposits at a depth of 1310 m in the Shenhu area of the South China Sea was conducted. The experimental results indicate that the particle size in the hydrate sediment samples are mainly distributed in the range from 7.81 µm to 21.72 µm, and the average particle size decreases as the depth of the burial increases. The X-ray CT analytical images and surface characteristics SEM scan images suggest that the sediment is mostly silty clay. There are a large number of bioplastics in the sediment, and the crack inside the core may be areas of hydrate formation. | Xin LYU Qingping LI Yang GE Junlong ZHU Shouwei ZHOU Qiang FU | 2021 | Frontiers in Energy2021，15，2： | 0 |
| 8 | Analysis of physical properties of gas hydrate-bearing unconsolidated sediment samples from the ultra-deepwater area in the South China Sea显示文摘Marine natural gas hydrate has recently attracted global attention as a potential new clean energy source. Laboratory measurements of various physical properties of gas hydrate-bearing marine sediments can provide valuable information for developing efficient and safe extraction technology of natural gas hydrates. This study presents comprehensive measurement results and analysis of drilled hydrate-bearing sediments samples recovered from Qiongdongnan Basin in the South China Sea. The results show that the gas hydrate in the core samples is mainly methane hydrate with a methane content of approximately 95%, and the other components are ethane and carbon dioxide. The saturation of the samples fluctuates from 2%–60%, the porosity is approximately 38%–43%, and the water content is approximately 30%–50%, which indicate that high water saturation means that timely drainage should be paid attention to during hydrate extraction. In addition, the median diameter of the sediment samples is mainly distributed in the range of 15 to 34 µm, and attention should be paid to the prevention and control of sand production in the mining process. Moreover, the thermal conductivity is distributed in the range of 0.75 to 0.96 W/(m·K) as measured by the flat plate heat source method. The relatively low thermal conductivity of hydrates at this study site indicates that a combined approach is encouraged for natural gas production technologies. It is also found that clay flakes and fine particles are attached to the surface of large particles in large numbers. Such characteristics will lead to insufficient permeability during the production process. | Xin Lyu Qingping Li Yang Ge Min Ouyang Hexing Liu Qiang Fu Junlong Zhu Shouwei Zhou | 2022 | Frontiers in Energy2022，16，3： | 0 |
| 9 | Pre‑rainy Season Rainstorms in South China—Risk Perception of the 11 April 2019 Rainstorm in Shenzhen City显示文摘With the acceleration of urbanization in South China, rainstorms and floods are threatening the safety of people in urban areas. The 11 April 2019(4·11 hereafter)rainstorm in Shenzhen City was a typical pre-rainy season rainstorm that caused great damage, yet such pre-rainy season events have not attracted sufficient attention in research.Risk perception of the public may indirectly affect their disaster preparedness, which is important for disaster management. In this study, we conducted a questionnaire survey that considered demographic factors and the level of risk perception, knowledge of risk, impact of the 4·11 rainstorm event on public risk perception, and degree of trust in the government. We used a two-factor model of risk perception to evaluate the factors that influenced public risk perception of the 4·11 rainstorm in Shenzhen. The main conclusions are: The 4·11 rainstorm improved public awareness of both risk and impact through the medium term, but the public’s perceived low probability of disaster occurrence and lack of knowledge of the pre-rainy season rainstorm phenomenon led to serious losses during this event. Although the public has high trust in the Shenzhen government, the management of rainstorm disasters in the pre-rainy season needs to be further improved. | Xuran Sun Wei Zhou Guoming Zhang Lianyou Liu Guangpeng Wang Mingzhu Xiang Yuting Xiao Shufeng Qu Shouwei Li Jiaxue Li | 2022 | International Journal of Disaster Risk Science2022，13，6： | 0 |
| 10 | Si Doping-Induced Electronic Structure Regulation of Single-Atom Fe Sites for Boosted CO_(2) Electroreduction at Low Overpotentials显示文摘Transition metal-based single-atom catalysts(TM-SACs)are promising alternatives to Au-and Ag-based electrocatalysts for CO production through CO_(2)reduction reaction.However,developing TM-SACs with high activity and selectivity at low overpotentials is challenging.Herein,a novel Fe-based SAC with Si doping(Fe-N-C-Si)was prepared,which shows a record-high electrocatalytic performance toward the CO_(2)-to-CO conversion with exceptional current density(>350.0 mA cm^(−2))and~100%Faradaic efficiency(FE)at the overpotential of<400 mV,far superior to the reported Fe-based SACs.Further assembling Fe-N-C-Si as the cathode in a rechargeable Zn-CO_(2)battery delivers an outstanding performance with a maximal power density of 2.44 mW cm^(−2)at an output voltage of 0.30 V,as well as high cycling stability and FE(>90%)for CO production.Experimental combined with theoretical analysis unraveled that the nearby Si dopants in the form of Si-C/N bonds modulate the electronic structure of the atomic Fe sites in Fe-N-C-Si to markedly accelerate the key pathway involving^(*)CO intermediate desorption,inhibiting the poisoning of the Fe sites under high CO coverage and thus boosting the CO_(2)RR performance.This work provides an efficient strategy to tune the adsorption/desorption behaviors of intermediates on singleatom sites to improve their electrocatalytic performance. | Changsheng Cao Shenghua Zhou Shouwei Zuo Huabin Zhang Bo Chen Junheng Huang Xin-Tao Wu Qiang Xu Qi-Long Zhu | 2023 | Research2023，，4： | 0 |
| 11 | Surface decorated Ni sites for superior photocatalytic hydrogen production显示文摘Precise construction of isolated reactive centers on semiconductors with well-controlled configurations affords a great opportunity to investigate the reaction mechanisms in the photocatalytic process and realize the targeted conversion of solar energy to steer the charge kinetics for hydrogen evolution.In the current research,we decorated isolated Ni atoms on the surface of CdS nanowires for efficient photocatalytic hydrogen production.X-ray absorption fine structure investigations clearly demonstrate the atomical dispersion of Ni sites on the surface of CdS nanowires.Experimental investigations reveal that the isolated Ni atoms not only perform well as the real reactive centers but also greatly accelerate the electron transfer via direct Ni-S coordination.Theoretical simulation further documents that the hydrogen adsorption process has also been enhanced over the semi-coordinated Ni centers through electronic coupling at the atomic scale. | Wenhuan Huang Tingting Bo Shouwei Zuo Yunzhi Wang Jiamin Chen Samy Ould-Chikh Yang Li Wei Zhou Jing Zhang Huabin Zhang | 2022 | SusMat2022，2，4： | 0 |
| 12 | Alcohols for hydrate inhibition-Different alcohols and different mechanisms显示文摘Methanol has been used to prevent hydrate formation in industrial handling of hydrate forming mixtures containing water for many decades.Ethanol is also used for the same purpose in countries that have easy access to low price ethanol,like for instance Brasil.Common to these small alcohols is that they also have surfactant properties that will promote hydrate formation,but when added to water in sufficient amounts,the hydrate prevention characteristics will dominate.These alcohols will primarily prevent heterogeneous hydrate formation on the interface between water and a separate hydrate phase.The effect of“alcohol”on both of these routes to hydrate formation are investigated and compared to experimental data.In particular we also investigate the effects of these small alcohols on Gibbs free energy for the hydrate formed on the new,shifted,stability conditions.Gibbs free energy is generally higher than hydrate formed from pure water.Enthalpies of hydrate formation are also higher for hydrate formed from water containing alcohols.These are negative numbers,so in absolute values released formation enthalpy is lower.The presence of these alcohols in water will also prevent homogeneous hydrate formation from dissolved hydrate formers in water.Glycols have more important roles in other routes to hydrate nucleation.Heterogeneous hydrate nucleation towards mineral surfaces is feasible in different ways.Polar hydrate formers like H2S and CO_(2)can adsorb directly on rust,and as discussed here,are able to form hydrate from adsorbed state on rust surface.Non-polar hydrocarbons like,for instance methane might get trapped in structured water and then nucleate to hydrate.Some research on this is published and further research is in progress.Glycols have very strong attraction to rust and corresponding chemical potentials for adsorbed glycols on rust are favourable enough to facilitate phase transition from glycols dissolved in water over to adsorption.Injection of glycol in gas processing plants has been used by industry for many years and in many cases it might even be economically and technically feasible compared to expensive drying units.Exceptions are situations that will lead to water/glycol freezing.But even in multiphase transport of hydrocarbons with various water cuts,mixtures of alcohols might be a technically efficient solution in which the small alcohols may be very efficient as discussed above and glycols may go through adsorption phase transition from water solution over to glycol film on rust and prevent hydrate nucleation towards rust surface.This possible strategy requires more theoretical work as well as experimental investigation.On the basis of thermodynamic analysis and calculations of hydrate formation from different routes,it is argued that real natural and industrial systems are unable to reach thermodynamic equilibrium.It is therefore a need for a consistent thermodynamic platform with a uniform reference system for all phases.We propose and demonstrate a residual thermodynamic model system for all phases. | Bjorn Kvamme Na Wei Jinzhou Zhao Shouwei Zhou Liehui Zhang Wantong Sun Navid Saeidi | 2022 | Petroleum2022，8，1： | 0 |
| 13 | Noble metal-free core-shell CdS/iron phthalocyanine Z-scheme photocatalyst for enhancing photocatalytic hydrogen evolution显示文摘Improving the separation efficiency of photogenerated carriers and broadening the light absorption range of the photocatalyst are two important factors for improving the performance of the photocatalyst.In this paper,a new and efficient Z-scheme Cd S/iron phthalocyanine(Cd S/Fe Pc)core-shell nanostructure composite material is prepared by a simple solid-phase reaction method.There are two key points in the preparation of composite materials:one is that hydrogen bonding energy is closely connected with Fe Pc,another is that Fe Pc can be uniformly assembled on Cd S nanoparticles.The photocatalytic hydrogen evolution(PHE)of the Cd S/Fe Pc nanocomposite(73.01μmol/h)is 2.6 times higher than that of pure Cd S(26.67μmol/h).In addition,after 4 photocatalytic cycles,the PHE of the Cd S/Fe Pc composite is still 92.3%of the first cycle.There are three reasons for this situation:(1)The Z-scheme heterojunction is formed to improve the separation efficiency of photogenerated carriers;(2)Fe Pc expands the visible light absorption range of Cd S;(3)The large core-shell contact area is favorable for the separation of photo-induced carriers at the interfaces.This research is conducive to the further development of new photocatalytic materials with high efficiency,low cost and simple preparation. | Weijie Zhang Xizhong Zhou Jinzhao Huang Shouwei Zhang Xijin Xu | 2022 | Journal of Materials Science & Technology2022，，20： | 0 |
| 14 | Routes to hydrate formation from water dissolved in gas and impact of mineral surfaces显示文摘Mineral surfaces adsorb water to extreme densities and corresponding low chemical potentials.This results in a dual effect in terms of hydrate.Water and slightly polar components adsorb directly on mineral surfaces and generate efficient conditions for hydrate nucleation.But due to the extremely low chemical potential of adsorbed water the hydrate nuclei formed towards mineral surfaces have to either detach from the vicinity of mineral surfaces,or be bridged by structured water in a dynamic attachment of hydrate cores some few nm outside mineral surfaces.During transport of gas(CH4,gas mixtures,CO2)the conventional water dew-point analysis will typically result in a substantially higher acceptable water concentration as compared to the concentration for adsorption of water from gas to rust surface.Direct formation of hydrate from water dissolved in gas is thermodynamically feasible,as discussed in open literature.In this work we demonstrate that it is also feasible in terms of mass transport.A new theory for enthalpy of hydrate dissociation has been extended to also direct hydrate formation from water dissolved in gas.The remaining question is whether direct hydrate formation from gas is also feasible in terms of transporting the hydrate formation heat away through a heat insulating medium.We propose further research strategies to enlighten this issue.Addition of glycols to critical points in processing of gas or transport is already in use by companies like for instance EQUINOR.There is,however,a need for more work on how efficient it is and if it can also be used for multiphase transport of hydrocarbons with significant water cut.Some research activities are in progress and briefly outlined here. | Bjørn Kvamme Na Wei Jinzhou Zhao Shouwei Zhou Liehui Zhang Wantong Sun Navid Saeidi | 2021 | Petroleum2021，7，4： | 0 |
| 15 | Sensitivity analysis of reservoir risk in marine gas hydrate drilling显示文摘It is easy to change the original temperature state of marine gas hydrate reservoir by drilling,which leads to uncontrollable decomposition of gas hydrate and release of large amount of gas.The decomposition gas will further escape and expand,and the reservoir will break and collapse due to its weak cementation characteristic,which will easily lead to a series of other potential risks.Therefore,in this study,based on the drilling process of marine gas hydrate,we establish the theoretical model and numerical calculation method of wellbore temperature field,analyze the influence on wellbore temperature of drilling fluid displacement,density,viscosity and injection temperature,and seawater depth.Then the sensitivity laws of reservoir risk in marine gas hydrate drilling are obtained.The results show that with the increase of drilling fluid displacement,density,viscosity and injection temperature,the temperature in lower well section and bottom hole will increase,making the increasing amplitude of temperature in hydrate reservoir larger and the scope of influence on hydrate reservoir stability bigger.Moreover,drilling is more likely to raise the temperature of reservoirs in shallow seawater depth,posing greater risks.Thus,engineering measures to avoid risks caused by rising reservoir temperature in marine gas hydrate reservoir drilling are presented.This study is of great significance to ensure the safety of marine gas hydrate reservoir drilling. | Wantong Sun Jun Pei Na Wei Jinzhou Zhao Jin Xue Shouwei Zhou Liehui Zhang Bjørn Kvamme Qingping Li Haitao Li Lin Jiang Chao Zhang Cong Li | 2021 | Petroleum2021，7，4： | 0 |
| 16 | Key issues in development of offshore natural gas hydrate显示文摘As a new clean energy resource in the 21st century,natural gas hydrate is considered as one of the most promising strategic resources in the future.This paper,based on the research progress in exploitation of natural gas hydrate(NGH)in China and the world,systematically reviewed and discussed the key issues in development of natural gas hydrate.From an exploitation point of view,it is recommended that the concepts of diagenetic hydrate and non-diagenetic hydrate be introduced.The main factors to be considered are whether diagenesis,stability of rock skeleton structure,particle size and cementation mode,thus NGHs are divided into 6 levels and used unused exploitation methods according to different types.The study of the description and quantitative characterization of abundance in hydrate enrichment zone,and looking for gas hydrate dessert areas with commercial exploitation value should be enhanced.The concept of dynamic permeability and characterization of the permeability of NGH by time-varying equations should be established.The‘Three-gas co-production’(natural gas hydrate,shallow gas,and conventional gas)may be an effective way to achieve early commercial exploitation.Although great progress has been made in the exploitation of natural gas hydrate,there still exist enormous challenges in basic theory research,production methods,and equipment and operation modes.Only through hard and persistent exploration and innovation can natural gas hydrate be truly commercially developed on a large scale and contribute to sustainable energy supply. | Shouwei ZHOU Qingping LI Xin LV Qiang FU Junlong ZHU | 2020 | Frontiers in Energy2020，14，3： | 0 |
