| 1 | Carbon dioxide adsorption of two-dimensional carbide MXenes显示文摘Two-dimensional carbide MXenes(Ti_3C_2T_x and V_2CT_x)were prepared by exfoliating MAX phases(Ti_3AlC_2 and V_2AlC)powders in the solution of sodium fluoride(NaF)and hydrochloric acid(HCl).The specific surface area(SSA)of as-prepared Ti_3C_2T_x was 21 m^2/g,and that of V_2CT_x was 9 m^2/g.After intercalation with dimethylsulfoxide,the SSA of Ti_3C_2T_x was increased to 66 m^2/g;that of V_2CT_x was increased to 19 m^2/g.Their adsorption properties on carbon dioxide(CO_2)were investigated under 0–4 MPa at room temperature(298 K).Intercalated Ti_3C_2T_x had the adsorption capacity of 5.79 mmol/g,which is close to the capacity of many common sorbents.The theoretical capacity of Ti_3C_2T_x with the SSA of 496 m^2/g was up to 44.2 mmol/g.Additionally,due to high pack density,MXenes had very high volume-uptake capacity.The capacity of intercalated Ti_3C_2T_(x )measured in this paper was 502 V·v^(–1).This value is already higher than volume capacity of most known sorbents.These results suggest that MXenes have some advantage features to be researched as novel CO_2 capture materials. | Bingxin WANG Aiguo ZHOU Fanfan LIU Jianliang CAO Libo WANG Qianku HU | 2018 | Journal of Advanced Ceramics2018，7，3： | 9 |
| 2 | Microfluidic generation of egg-derived protein microcarriers for 3D cell culture and drug delivery显示文摘Microcarriers have a demonstrated value for biomedical applications,in particular for drug delivery and three-dimensional cell culture.Attempts to develop this technique tend to focus on the fabrication of functional microparticles by using convenient methods with innovative but accessible materials.Inspired by the process of boiling eggs in everyday life,which causes the solidification of egg proteins,we present a new microfluidic‘‘cooking'approach for the generation of egg-derived microcarriers for cell culture and drug delivery.As the egg emulsion droplets are formed with exquisite precision during the microfluidic emulsification,the resultant egg microcarriers present highly monodisperse and uniform morphologies at the size range of hundred microns to one millimeter.Benefiting from the excellent biocompatibility of the egg protein components,the obtained microcarriers showed good performances of cell adherence and growth.In addition,after a freezing treatment,the egg microcarriers were shown to have interconnected porous structures throughout their whole sphere,could absorb and load different kinds of drugs or other active molecules,and work as microcarrier-based delivery systems.These features point to the potential value of the microfluidic egg microcarriers in biomedicine. | Yuxiao Liu Qian Huang Jie Wang Fanfan Fu Jianan Ren Yuanjin Zhao | 2017 | Science Bulletin2017，62，18： | 8 |
| 3 | Research progress on construction and energy storage performance of MXene heterostructures显示文摘MXenes are a family of two-dimensional (2D) transition metal carbides, carbonitrides/nitrides with superior physical and chemical properties, which have attracted extensive attention since the discovery in 2011. The impressive electrochemical activity of MXene makes it one of the most potential electrode materials in rechargeable batteries and supercapacitors. However, single-component MXene electrodes are difficult to achieve high specific capacity, efficient ion/electron transport, and high stability compatibility in an electrochemical environment. Studies have shown that it is an effective method to introduce nanomaterials between MXene layers to construct heterostructures and to improve the electrochemical performance through the synergistic effect among the components in the heterostructures. The introduction of nanomaterials can effectively suppress the restacking of MXene nanosheets, shorten the diffusion path of ions and promote the electrolyte transport, which is beneficial to enhance the rate performance of MXene;moreover, the excellent mechanical flexibility of MXene can reduce the volume expansion of nanomaterials during charge/discharge, thereby effectively protecting the integrity of the electrode structure and improving the cycling stability. Therefore, in this review, combined with theoretical calculations, we summarize the recent advances of MXene heterostructures in terms of synthesis strategies and energy storage applications, including supercapacitors, metal-ions batteries (Li, Na, K, Mg, Zn, Al) and metal anode protection. Furthermore, potential challenges and application perspectives for MXene heterostructures are also outlined. | Fanfan Liu Sen jin Qixun Xia Aiguo Zhou Li-Zhen Fan | 2021 | Journal of Energy Chemistry2021，30，11： | 5 |

| 5 | Integration of homogeneous and heterogeneous nucleation growth via 3D alloy framework for stable Na/K metal anode显示文摘Sodium/Potassium(Na/K)metal anodes have been considered as the promising anodes for next-generation Na/K secondary batteries owing to their ultrahigh specific capacity,low redox potential and low cost.However,their practical application is still hampered due to unstable solid electrolyte interphase,infinite volume change,and dendrite growth.Herein,we design a 3D-Na_(3)Bi/3D-K_(3)Bi alloy host which enables the homogeneous and heterogeneous nucleation growth of Na/K metal.The unique structure with periodic alternating of electron and ion conductivity improves the mass transfer kinetics and prevents the volume expansion during cycling.Meanwhile,the sodiophilicity of Na_(3)Bi/potassiophilicity of K_(3)Bi framework can avoid dendritic growth.Cycling lifespans over 700 h with 1 mAh cm^(−2)for 3D-Na_(3)Bi@Na electrode and about 450 h with 1 mAh cm^(−2)for 3D-K_(3)Bi@K electrode are achieved,respectively.3D-Na_(3)Bi@Na||Na_(3)V_(2)(PO_(4))3 full battery shows sustainable cycle performance over 400 cycles.This design provides a simple but effective approach for achieving safety of sodium/potassium metal anodes. | Shufen Ye Lifeng Wang Fanfan Liu Pengcheng Shi Yan Yu | 2021 | eScience2021，1，1： | 3 |
| 6 | A new coordinated backup protection scheme for distribution network containing distributed generation显示文摘This paper proposes a new backup protection scheme,named coordinated backup protection(CBP)scheme,for distribution networks containing distributed generation.The proposed protection scheme takes into account the issues faced by traditional backup protection,such as difficulty in setting parameters and complex cooperation,and considers the features of distribution networks,such as changeable power flow because of high penetration of distributed generation sources and insufficient measuring quantities.The CBP scheme includes two aspects:coordinated substation protection and regional master substation protection,who also work as nearby backup protection and remote backup protection respectively.The two protections support each other by local information coordination and regional information sharing,in order to improve the reliability of fault identification.The configuration principles and performances of the proposed backup protection scheme are addressed in the paper.Different fault conditions in the IEEE 14-node system have been used to illustrate and verify the feasibility of the CBP scheme. | Jinghan He Lin Liu Fanfan Ding Changcheng Li Dahai Zhang | 2017 | Protection and Control of Modern Power Systems2017，2，1： | 3 |
| 7 | Effect of acupuncture treatment on smoking cessation in smokers from Hong Kong显示文摘OBJECTIVE: To analyze the characteristics of smokers treated with acupuncture for smoking cessation in Hong Kong.METHODS: A total of 2051 subjects were recruited in a clinical pilot research project 'acupuncture for smoking cessation', which was conducted jointly by Institute of Acupuncture and Moxibustion, China Academy of Chinese Medical Sciences and Hong Kong Pok Oi Hospital from January of 2011 to December of 2013. The characteristics of study subjects, including baseline information, smoking background, intention to quit and influencing factors were analyzed.RESULTS: The majority of subjects treated with acupuncture for smoking cessation in Hong Kong was male(66.7%), but the proportion of female smokers in this study(33.3%) was higher than that of female smokers in Hong Kong population(13.8%, P <0.05). Subjects were at the mean age of 43.83 years old, of which the percentage of females aged 31-40 years was the highest(38.8%, P < 0.05). The mean duration of smoking was 25.49 years. The number of cigarettes smoked per day was 17.57 cigarettes.Fagerstrom Test for Nicotine Dependence(FTND)was 5.29 points. Most of the subjects had attempted quitting smoking(81.42%). The confidence index(7.44 points) and the readiness to quit smoking(8.13 points) were high. Subjects quitting smoking were mostly due to health cause(81.91%). The majority of subjects were at the level of middle school(61.63%). The higher the educational level was, the lower the tobacco dependence was and the higher the confidence in successfully quitting smoking was. 50.27% of subjects chose acupuncture for smoking cessation mainly through friends, television and network publicity. Subjects who had received acupuncture had the highest confidence index, while those who wanted to try a new method had the lower confidence index.CONCLUSION: Acupuncture for smoking cessation was more popular in female smokers, especially those aged 31-40 years. The effectiveness of acupuncture-smoking cessation was most significant in the smokers over 60. | Wang Yingying Liu Zhao Zhang Ou Chen Min Huang Lingling Wu Yuan Zhang Fanfan Wu Guanyi He Xiuqing Yang Jinsheng | 2016 | Journal of Traditional Chinese Medicine2016，36，5： | 3 |
| 8 | Azimuthal vector beam exciting silver triangular nanoprisms for increasing the performance of surface-enhanced Raman spectroscopy显示文摘Surface-enhanced Raman spectroscopy(SERS)with high-sensitivity performance is a very necessary detection technology.Here,we present a method for increasing the performance of SERS based on silver triangular nanoprism arrays(ATNAs)vertically excited via a focused azimuthal vector beam(AVB).The ATNA substrates with different structural parameters are prepared based on the traditional self-assembled and modified film lift-off technique.Based on a theoretical model established adopting the structural parameters of the ATNA substrates,theoretical simulation results show that AVB excitation can achieve greater electric-field enhancement than linearly polarized beam(LPB)excitation.Experimental result indicates that SERS sensitivity obtained via AVB excitation is 10^-13M(1 M=1 mol/L)using rhodamine 6 G(R6 G)as the target analyte,which is 2 orders of magnitude lower than that of LPB excitation(10^-11M).Meanwhile,the uniformity and reproducibility of the ATNA substrates are examined using Raman mapping and batch-to-batch measurement,respectively,and the Raman enhancement factor is calculated to be^3.3×10^7.This method of vector light field excitation may be used to improve the SERS performance of the substrates in fields of ultra-sensitive Raman detection. | LU ZHANG WENDING ZHANG FANFAN LU ZHIQIANG YANG TIANYANG XUE MIN LIU CHAO MENG PENG LI DONG MAO TING MEI JIANLIN ZHAO | 2019 | Photonics Research2019，7，12： | 3 |

| 10 | Ferrocene-induced switchable preparation of metal-nonmetal codoped tungsten nitride and carbide nanoarrays for electrocatalytic HER in alkaline and acid media显示文摘Transition metal nitride/carbide(TMN/C)have been actively explored as low-cost hydrogen evolution reaction(HER)electrocatalysts owing to their Pt-like physical and chemical properties.Unfortunately,pure TMN/C suffers from strong hydrogen adsorption and lacks active centers for water dissociation.Herein,we developed a switchable WO_(3)-based in situ gas–solid reaction for preparing sophisticated Fe-N doped WC and Fe-C doped WN nanoarrays.Interestingly,the switch of codoping and phase can be effectively manipulated by regulating the amount of ferrocene.Resultant Fe-C-WN and Fe-N-WC exhibit robust electrocatalytic performance for HER in alkaline and acid electrolytes,respectively.The collective collaboration of morphological,phase and electronic effects are suggested to be responsible for the superior HER activity.The smallest|ΔGH*|value of Fe-NWC indicates preferable hydrogen-evolving kinetics on the Fe-N-WC surface for HER under acid condition,while Fe-C-WN is suggested to be beneficial to the adsorption and dissociation of H_(2)O for HER in alkaline electrolyte. | Jian Zhou Fanfan Wang Haiqing Wang Shuxian Hu Weijia Zhou Hong Liu | 2023 | Nano Research2023，16，2： | 2 |

| 13 | Recent advances based on Mg anodes and their interfacial modulation in Mg batteries显示文摘Magnesium(Mg)batteries(MBs),as post-lithium-ion batteries,have received great attention in recent years due to their advantages of high energy density,low cost,and safety insurance.However,the formation of passivation layers on the surface of Mg metal anode and the poor compatibility between Mg metal and conventional electrolytes during charge-discharge cycles seriously affect the performance of MBs.The great possibility of generating Mg dendrites has also caused controversy among researchers.Moreover,the regulation of Mg deposition and the enhancement of battery cycle stability is largely limited by interfacial stability between Mg metal anode and electrolyte.In this review,recent advances in interfacial science and engineering of MBs are summarized and discussed.Special attention is given to interfacial chemistry including passivation layer formation,incompatibilities,ion transport,and dendrite growth.Strategies for building stable electrode/interfaces,such as anode designing and electrolyte modification,construction of artificial solid electrolyte interphase(SEI)layers,and development of solid-state electrolytes to improve interfacial contacts and inhibit Mg dendrite and passivation layer formation,are reviewed.Innovative approaches,representative examples,and challenges in developing high-performance anodes are described in detail.Based on the review of these strategies,reference is provided for future research to improve the performance of MBs,especially in terms of interface and anode design. | Fanfan Liu Guoqin Cao Jinjin Ban Honghong Lei Yan Zhang Guosheng Shao Aiguo Zhou Li zhen Fan Junhua Hu | 2022 | Journal of Magnesium and Alloys2022，10，10： | 1 |
| 14 | Efficacy and safety of darbepoetin alfa injection replacing epoetin alfa injection for the treatment of renal anemia in Chinese hemodialysis patients:A randomized,open-label,parallel-group,noninferiority phase III trial显示文摘Background:This study was to explore the clinical efficacy and safety of darbepoetin alfa injection replacing epoetin alfa injection(recombinant human erythropoietin injection,rHuEPO)for the treatment of anemia associated with chronic kidney failure in Chinese patients undergoing hemodialysis.Method:This study was a multicenter,randomized,open-label,intergroup parallel control phase III noninferiority trial from April 19,2013 to September 9,2014 at 25 sites.In this study,the members of the darbepoetin alfa group underwent intravenous administration once per week or once every two weeks.The members of the control drug epoetin alfa group underwent intravenous administration two or three times per week.All subjects underwent epoetin alfa administration during the 8-week baseline period.After that,subjects were randomly assigned to the darbepoetin alfa group or epoetin alfa group.The noninferiority in the changes of the average Hb concentrations from the baseline to the end of the evaluation period(noninferiority threshold:-1.0 g/dl)was tested between the two treatments.The time-dependent hemoglobin(Hb)concentration and the maintenance rate of the target Hb concentration(the proportion of subjects with Hb concentrations between 10.0 and 12.0 g/dl)were also evaluated.Iron metabolism,including changes in the serum iron,total iron-binding capacity,ferritin,transferrin saturation,and comparisons of the dose adjustments between the two groups during the treatment period were analyzed further.Adverse events(AEs)were also observed and compared,and the safety was analyzed between the two treatment groups.The conversion rate switching from epoetin alfa to darbepoetin alfa was also discussed.SAS?software version 9.2 was used to perform all statistical analyses.Descriptive statistics were used for all efficacy,safety,and demographic variable analyses,including for the primary efficacy indicators.Results:Four hundred and sixty-six patients were enrolled in this study,and ultimately 384 cases were analyzed for safety,including 267 cases in the darbepoetin alfa group and 117 cases in the epoetin alfa group.There were 211 cases in the per-protocol set,including 152 cases in the darbepoetin alfa group and 59 cases in the epoetin alfa group.The changes in the average Hb concentrations from the baseline to the end of the evaluation period were-0.07 and-0.15 g/dl in the darbepoetin alfa group and epoetin alfa group respectively.The difference between the two groups was 0.08 g/dl(95%confidence interval[CI]:-0.22 to 0.39),and the lower limit of the 95%CI was-0.22>-1.0 g/dl.The average Hb concentrations of the two groups were 10.88-11.43 g/dl(darbepoetin alfa)and 10.91-11.38 g/dl(epoetin alfa)during the study period of Weeks 0-28,with the maintenance rates of the target Hb concentration ranging within 71%-87%and 78%-95%in the darbepoetin alfa group and epoetin alfa group respectively.During the period of comparison between the two groups,the incidence of AEs in the darbepoetin alfa group was 61.42%,while in the epoetin alfa group it was 56.41%.All of the adverse events and reactions in the study were those commonly associated with hemodialysis.Conclusion:The overall efficacy and safety of darbepoetin alfa for the treatment of Chinese renal anemia patients undergoing hemodialysis are consistent with those of epoetin alfa. | Bicheng Liu Nan Chen Jinghong Zhao Aiping Yin Xiongfei Wu Changying Xing Gengru Jiang Junzhou Fu Mei Wang Rong Wang Jianying Niu Ping Fu Zhaohui Ni Fanfan Hou Jiuyang Zhao Jing Chen Yuqing Chen Wei Shi Jianghua Chen Wenge Li Gang Xu Ling Zhong Wenhu Liu Guohua Ding Yuichiro Kondo Changhe Yue Changlin Mei | 2022 | Chronic Diseases and Translational Medicine2022，8，2： | 1 |
| 15 | Darbepoetin alfa injection versus epoetin alfa injection for treating anemia of Chinese hemodialysis patients with chronic kidney failure:A randomized,open-label,parallel-group,non-inferiority Phase III trail显示文摘Background:Erythropoietin is a glycoprotein that mainly regulates erythropoiesis.In patients with chronic renal failure with anemia,darbepoetin alfa can stimulate erythropoiesis,correct anemia,and maintain hemoglobin levels.This study was designed to demonstrate the efficacy and safety of darbepoetin alfa injections as being not inferior to epoetin alfa injections(Recombinant Human Erythropoietin injection,rHuEPO)when maintaining hemoglobin(Hb)levels within the target range(10.0-12.0 g/dL)for the treatment of renal anemia.Methods:Ninety-five patients were enrolled in this study from April 15,2013 to April 10,2014 at 25 sites.In this study,patients(n=95)aged 18-70 years were randomized into a once per week intravenous darbepoetin alfa group(n=56)and a twice or three times per week intravenous epoetin alfa group(n=39)for 28 weeks,who had anemia with hemoglobin levels between 6 g/dL and 10 g/dL due to chronic kidney disease(CKD)and were undergoing hemodialysis or hemofiltration with ESA-naive(erythropoiesis stimulating agent-naive).The primary efficacy profile was the mean Hb level(the non-inferiority margin was-1.0 g/dL,week 21-28);the secondary efficacy profiles were the Hb increase rate(week 0-4),the target Hb achievement cumulative rate and time,the change trends of the Hb levels,and the target Hb maintenance ratio.Adverse events(AEs)were observed and compared,and the efficacy and safety were analyzed between the two treatment groups.Additionally,the frequencies of dose adjustments between the darbepoetin alfa and epoetin alfa groups were compared during the treatment period.SAS?software version 9.2 was used to perform all statistical analyses.Descriptive statistics were used for all efficacy,safety,and demographic variable analyses,including for the primary efficacy indicators.Results:The mean Hb level was 11.3 g/dL in the darbepoetin alfa group and 10.7 g/dL in the epoetin alfa group,respectively;the difference of the lower limits of the 95%confidence intervals(CI)between the two groups was 0.1 g/dL(>-1.0 g/dL),and non-inferiority was proven;the Hb levels started to increase in the first four weeks at a similar increase rate;no obvious differences were observed between the groups in the target Hb achievement cumulative rates,and the Hb levels as well as the target Hb level maintenance rate changed over time.The incidence of AEs was 62.5%in the darbepoetin alfa group and 76.9%in the epoetin alfa group.All the adverse events observed in the study were those commonly associated with hemodialysis.Conclusion:Darbepoetin alfa intravenously once per week can effectively increase Hb levels and maintain the target Hb levels well,which makes it not inferior to epoetin alfa intravenously twice or three times per week.Darbepoetin alfa shows an efficacy and safety comparable to epoetin alfa for the treatment of renal anemia. | Nan Chen Changying Xing Jianying Niu Bicheng Liu Junzhou Fu Jiuyang Zhao Zhaohui Ni Mei Wang Wenhu Liu Jinghong Zhao Ling Zhong Xiongfei Wu Wenge Li Yuqing Chen Wei Shi Jianghua Chen Aiping Yin Ping Fu Rong Wang Gengru Jiang Fanfan Hou Guohua Ding Jing Chen Gang Xu Yuichiro Kondo Yuliang Su Changlin Mei | 2022 | Chronic Diseases and Translational Medicine2022，8，1： | 1 |

| 17 | Synthesis and photoluminescent properties of Sm^(3+)-activated La_(3)Si_(6)N_(11)as an orange-red emitting phosphor显示文摘A series of Sm^(3+)-doped La_(3)Si_(6)N_(11)phosphor materials we re synthesized by a high temperature solid-state reaction method.The crystal structure,micro structure,photoluminescence properties,decay curves as well as thermal quenching properties of the as-prepared phosphors were investigated systematically.The excitation spectra contain a wide asymmetric band below 350 nm originating from the host absorption,several sharp excitation peaks in the range of 300-550 nm corresponding to f-f transition of Sm^(3+).Under the excitation of 369 and 414 nm light,the phosphors exhibit strong narrow-band orangered emission peaked at 605 nm.The average decay time of La_(2.99)Si_(6)N_(11):0.01 Sm^(3+)sample is fitted to be0.38 ms and the CIE coordinates were calculated to be(0.6105,0.3833).For water resistance,La_(3)Si_(6)N_(11):Sm^(3+)is better than K_(2)SiF_(6):Mn^(4+)phosphor.After soaking in deionized water for 300 min,the La_(3)Si_(6)N_(11):Sm^(3+)sample retains approximately 80%of its initial relative emission intensity.When the temperature rises to 423 K(150℃),the emission intensity of La_(2.99)Si_(6)N_(11):0.01 Sm^(3+)sample remains 85%in co mparison to that of room tempe rature.The activation energy was calculated to be 0.63253 eV,which is higher than those of Sm^(3+)-activated oxide phosphors,indicating that the phosphor has relatively good thermal stability. | Lili Liu Junfei Zhang Fanfan Xu Fu Du Fengli Yang Jiaqing Peng Xinyu Ye | 2021 | Journal of Rare Earths2021，39，2： | 1 |
| 18 | Porous polymer electrolytes for long-cycle stable quasi-solid-state magnesium batteries显示文摘The development of applicable electrolytes is the key point for high-performance rechargeable magnesium batteries(RMBs).The use of liquid electrolyte is prone to safety problems caused by liquid electrolyte leakage.Polymer-based gel electrolytes with high ionic conductivity,great flexibility,easy processing,and high safety have been studied by many scholars in recent years.In this work,a novel porous poly(vinylidene fluoride-co-hexafluoropropylene)(PVDF-HFP)membrane is prepared by a phase inversion method.By immersing porous PVDF-HFP membranes in MgCl2-AlCl3/TEGDME(Tetraethylene glycol dimethyl ether)electrolytes,porous PVDF-HFP based electrolytes(PPEs)are formed.The PPE exhibits a high ionic conductivity(4.72×10^(-4) S cm-1,25℃),a high liquid electrolyte uptake of 162%,as well as a wide voltage window(3.1 V).The galvanostatic cycling test of Mg//Mg symmetric cell with PPE reveals that the reversible magnesium ion(Mg^(2+))plating/stripping occurs at low overpotentials(~0.13 V).Excellent long cycle stability(65.5 mAh g^(-1) over 1700 cycles)is achieved for the quasisolid-state RMB assembled with MoS2/C cathode and Mg anode.Compared with the liquid electrolyte,the PPE could effectively reduce the side reactions and make Mg^(2+)plating/stripping more uniformly on the Mg electrode side.This strategy herein provides a new route to fabricate high-performance RMB through suitable cathode material and polymer electrolyte with excellent performance. | Tiantian Wang Xudong Zhao Fanfan Liu Li-Zhen Fan | 2021 | Journal of Energy Chemistry2021，30，8： | 1 |
| 19 | Chondrogenic differentiation of mouse embryonic stem cells promoted by mature chondrocytes显示文摘In order to direct embryonic stem (ES) cells to differentiate into chondrocytes, a chondrogenic envi-ronment provided by mature chondrocytes was investigated. Flk-1 positive cells sorted from pre-differentiated mouse ES cells were mixed with adult porcine articular chondrocytes, seeded on biodegradable scaffolds, and then implanted subcutaneously into nude mice. The cell-scaffold com-plexes formed cartilage tissues after 4 weeks, which was demonstrated by histology and anti-type II collagen antibody staining. Positive staining of mouse Major Histocompatibility Complex class I molecules confirmed that part of the chondrocytes were derived from mouse ES cells. The current study established a new approach for directing ES cell differentiation. | XIE Feng, ZHANG WenJie, CHEN FanFan, ZHOU GuangDong, CUI Lei, LIU Wei & CAO YiLin Department of Plastic and Reconstructive Surgery, Shanghai 9th People’s Hospital National Tissue Engineering Center of China, School of Medicine, Shanghai JiaoTong University, Shanghai 200011, China | 2008 | Science China(Life Sciences)2008，51，9： | 1 |
| 20 | Prediction of methane production performances based on determination of organic components for different vegetable wastes显示文摘The rapid development of the economy has led to rapid consumption of fossil fuels,which results in extremely serious environmental problems.Biomass energy has been accepted as a way to reduce the usage of fossil fuels due to its cleanliness and renewability.In this study,vegetable wastes(VWs),an abundant kind of biomass resource,were treated by anaerobic digestion(AD)to be converted into methane.The total solids(TS),volatile solids(VS),elemental contents,and organic components of 17 kinds of typical VWs were systematically determined.The methane production performances were then measured and ranged from 120.1 mL/g VS(for pepper stem)to 377.7 mL/g VS(for bok choy).To easily and quickly predict the methane yields of VWs,a curvilinear relationship between different organic compositions(e.g.,cellulose,hemicellulose,lignin,non-structural carbohydrate,protein,and VFA contents)and methane production was established and proved to be a useful tool for methane prediction.Four kinetic models(first-order model,Fitzhugh model,Cone model,modified Gompertz model)were applied to simulate the process of AD,and Cone and modified Gompertz models were shown to describe the AD process well.This study will not only provide basic data about the characteristics and methane production of 17 kinds of VWs but also contribute a method for predicting the methane yields of vegetable wastes,which is also valuable in future agro-industrial applications. | Fanfan Cai Hu Yan Ruihong Zhang Guangqing Liu Chang Chen | 2019 | International Journal of Agricultural and Biological Engineering2019，12，3： | 0 |
