| 1 | Preparation and Properties of Cellulose Nanomaterials显示文摘Cellulose is the most abundant biomass material in nature and it is mainly extracted from natural or lignocellulosic fibers.After purification,cellulose fibers exhibit two interesting features for their further transformation into nanomaterials:a hierarchical and multi-level strcture,and a semicrystalline microstructure.Different forms of cellulose nanomaterials,resulting from a top-down deconstructing strategy(cellulose nanocrystals(CNCs),cellulose nanofibrils(CNFs))or bottom-up strategy(bacterial cellulose(BC))can be prepared.Multiple mechanical shearing actions applied to cellulosic fibers release more or less the nanofibrils individually.A controlled strong acid hydrolysis treatment can be applied to cellulosic fibers allowing dissolution of non-crystalline domains.Such cellulose nanomaterials have been the focus of an exponentially increasing number of works or reviews devoted to understand such materials and their applications.They have a high potential for an emerging industry.In the nanoscale,cellulose exhibits specific properties broadening the applications of this naturally occurring polymer.An overview of existing methods for the preparation of cellulose nanomaterials and their specific properties that outperform and contrast with cellulose in the microscale is proposed. | Alain Dufresne | 2020 | Paper And Biomaterials2020，5，3： | 19 |

| 3 | Overview of biomass pretreatment for cellulosic ethanol production显示文摘Bioconversion of lignocellulosic biomass to ethanol is significantly hindered by the structural and chemical complexity of biomass,which makes these materials a challenge to be used as feedstocks for cellulosic ethanol production.Cellulose and hemicellulose,when hydrolyzed into their component sugars,can be converted into ethanol through well established fermentation technologies.However,sugars necessary for fermentation are trapped inside the crosslinking structure of the lignocellulose.Hence,pretreatment of biomass is always necessary to remove and/or modify the surrounding matrix of lignin and hemicellulose prior to the enzymatic hydrolysis of the polysaccharides(cellulose and hemicellulose)in the biomass.Pretreatment refers to a process that converts lignocellulosic biomass from its native form,in which it is recalcitrant to cellulase enzyme systems,into a form for which cellulose hydrolysis is much more effective.In general,pretreatment methods can be classified into three categories,including physical,chemical,and biological pretreatment.The subject of this paper emphasizes the biomass pretreatment in preparation for enzymatic hydrolysis and microbial fermentation for cellulosic ethanol production.It primarily covers the impact of biomass structural and compositional features on the pretreatment,the characteristics of different pretreatment methods,the pretreatment study status,challenges,and future research targets. | Yi Zheng Zhongli Pan Ruihong Zhang | 2009 | International Journal of Agricultural and Biological Engineering2009，2，3： | 13 |

| 5 | A METHOD OF PREPARING SPHERICAL NANO-CRYSTAL CELLULOSE WITH MIXED CRYSTALLINE FORMS OF CELLULOSE Ⅰ AND Ⅱ显示文摘A new kind of nano-crystal cellulose (NCC) prepared from natural cotton fiber has been obtained by the method of acid hydrolysis. Compared to most other nanophase materials that derive from inorganic materials, our products are prepared from natural cotton fibers. The products are of spherical shape with mixed crystal forms of cellulose Ⅰ and Ⅱ. The preparation conditions determine the properties of the products. Prior treatment is a critical procedure. The properties of the products are also strongly affected by such conditions as the kinds of acids used, the ratio of the acid mixture, the acid concentration, the ultrasonic agitation time and hydrolysis temperature. The number average molecular weight of NCC is determined by gel permeation chromatography (GPC). The particle size and shape were determined by transmission electron microscopy (TEM). X-ray diffraction was used to detect the crystallinity and average crystallite size of the particle. | Xiao-fang Li En-yong Ding Guo-kang Li Laboratory of Cellulose and Lignocellulosics Chemistry, Guangzhou Institute of Chemistry, Chinese Academy of Sciences, Guangzhou 510650 China College of Material Science and Engineering South China University of Technology, Guangzhou 510641, China | 2001 | Chinese Journal of Polymer Science2001，19，3： | 12 |
| 6 | Celulose Paper-based Strapping Products for Green/Sustainable Packaging Needs显示文摘Paper products such as corrugated paperboards are the most common green packaging materials, which are renewable, sustainable, recyclable and biodegradable. However, the plastic or metal straps used to secure the carton boxes are not so green. At the end of packaging, the carton boxes can be recycled, but the plastic/metal straps have to be sorted out for disposal separately. This review focuses on: 1) the global trend of green packaging;2) conventional plastic/metal strapping materials for carton boxes;3) conventional market pulp baling with steel wire as the tying materials;4) cellulose fiber-based materials for strapping market pulp bales and carton boxes. New generation of cellulose paper straps are being developed for more challenging applications with superior strength properties and repulpability. | Zhibin He Amit Chowdhury Li Tong Mike Reynolds Yonghao Ni | 2019 | Paper And Biomaterials2019，4，3： | 11 |

| 8 | Changes in Lignin Content and Activity of Related Enzymes in the Endocarp During the Walnut Shell Development Period显示文摘Lignification was observed using the phloroglucinol–HCl method and the content of lignin,cellulose,and polyphenol and the activity of related enzymes were measured during development with the materials of walnut of ‘Zanmei' and ‘Zhenzhuxiang'.Results showed that lignification occurred at the beginning of June,initially took shape in mid-June and finished in late July.From shell lignification to harvest,the concentrations of lignin,cellulose,and phenolic content increased before harvest,but phenolic content decreased slightly.The activities of both POD and PAL decreased and PPO varied somewhat.Correlation analysis showed lignin content to be significantly positively correlated with the cellulose content.Phenolic content had a significant positive correlation with that of lignin.Phenolic content was positively correlated with cellulose.The activity of POD had a significant negative correlation with lignin,cellulose,and phenolic content,but it was positively correlated with the activity of PAL. | ZHAO Shugang WEN Jing WANG Hongxia ZHANG Zhihua LI Xibo | 2016 | Horticultural Plant Journal2016，2，3： | 11 |
| 9 | A novel function for the cellulose binding module of cellobiohydrolase I显示文摘A homogeneous cellulose-binding module(CBM)of cellobiohydrolase I(CBHI)from Trichoderma pseudokoningii S-38 was obtained by the limited proteolysis with papain and a series of chromatographs filtration.Analysis of FT-IR spectra demonstrated that the structural changes result from a weakening and splitting of the hydrogen bond network in cellulose by the action of CBMCBHI at 40℃for 24 h.The results of molecular dynamic simulations are consistent with the experimental conclusions, and provide a nanoscopic view of the mechanism that strong and medium H-bonds decreased dramatically when CBM was bound to the cellulose surface.The function of CBMCBHI is not only limited to locating intact CBHI in close proximity with cellulose fibrils,but also is involved in the structural disruption at the fibre surface.The present studies provided considerable evidence for the model of the intramolecular synergy between the catalytic domain and their CBMs. | WANG LuShan 1,2 ,ZHANG YuZhong 1 &GAO PeiJi 1 1State Key Laboratory of Microbial Technology,Shandong University,Jinan 250100,China 2Beijing Laboratory of Nanoscale Physics&Devices,Chinese Academy of Sciences,Beijing 100080,China | 2008 | Science China(Life Sciences)2008，51，7： | 10 |

| 15 | All-in-one cellulose based hybrid tribo/piezoelectric nanogenerator显示文摘Aybrid tribo/piezoelectric nanogenerators (HTPENG) have been proven to be highly efficient and versatile as far as the collection and conversion of ambient energy are concerned, and the introduction of flexible and green materials is a key step for their potential applications. Here, we developed a HTPENG by using nitrocellulose nanofibril paper as the triboelectric layer and BaTiCVMWCNT@ bacterial cellulose paper as the piezoelectric layer. The output of the triboelelctric paper has considerable performance as fluorinated ethylene propylene, and the output of piezoelectric paper is more than ten times higher than the BTO/polydimethylsiloxane structure. The integrated outputs of the sandwich structured HTPENG are 18 V and 1.6 pA·cm^-2, which are capable of lighting up three LED bulbs and charging a 1 pF capacitor to 2.5 V in 80 s. In addition, the voltage signal generated by the HTPENG in contact-separation mode can be used for dynamic pressure detection. The linear range of dynamic pressure is from 0.5 to 3 N·cm^-2 with a high sensitivity of 8.276 V·cm^-2·N^-1 and a detection limit of 0.2 N·cm^-2. This work provides new insights into the design and application of cellulose-based hybrid nanogenerators with high flexibility and simple structure. | Ming Li Yang Jie Li-Hua Shao Yilin Guo Xia Cao Ning Wang Zhong Lin Wang | 2019 | Nano Research2019，12，8： | 9 |
| 16 | Synthesis, isolation and characterization of methyl levulinate from cellulose catalyzed by extremely low concentration acid显示文摘A direct synthesis of methyl levulinate from cellulose alcoholysis in methanol medium under mild condition(180 210 C)catalyzed by extremely low concentration sulfuric acid(0.01 mol/L)and the product isolation were developed in this study.Effects of different process variables towards the catalytic performance were performed as a function of reaction time.The results indicated that sulfuric acid concentration,temperature and initial cellulose concentration had significant effects on the synthesis of methyl levulinate.An optimized yield of around 50%was achieved at 210 C for 120 min with sulfuric acid concentration of 0.01 mol/L and initial cellulose concentration below 100 g/L.The resulting product mixture was isolated by a distillation technique that combines an atmospheric distillation with a vacuum distillation where n-dodecane was added to help distill the heavy fraction.The light fraction including mainly methanol could be reused as the reaction medium without any substantial change in the yield of methyl levulinate.The chemical composition and structural of lower heavy fraction were characterized by GC/MS,FTIR,1H-NMR and13C-NMR techniques.Methyl levulinate was found to be a major ingredient of lower heavy fraction with the content over 96%.This pathway is efficient,environmentally benign and economical for the production of pure levulinate esters from cellulose. | Hui Li Lincai Peng Lu Lin Keli Chen Heng Zhang | 2013 | Journal of Energy Chemistry2013，22，6： | 9 |
| 17 | Lignocellulosic biomass as sustainable feedstock and materials for power generation and energy storage显示文摘Lignocellulosic biomass has attracted great interest in recent years for energy production due to its renewability and carbon-neutral nature.There are various ways to convert lignocellulose to gaseous,liquid and solid fuels via thermochemical,chemical or biological approaches.Typical biomass derived fuels include syngas,bio-gas,bio-oil,bioethanol and biochar,all of which could be used as fuels for furnace,engine,turbine or fuel cells.Direct biomass fuel cells mediated by various electron carriers provide a new direction of lignocellulose conversion.Various metal and non-metal based carriers have been screened for mediating the electron transfer from biomass to oxygen thus generating electricity.The power density of direct biomass fuel cells can be over 100 mW cm^(-2),which shows promise for practical applications.Lignocellulose and its isolated components,primarily cellulose and lignin,have also been paid considerable attention as sustainable carbonaceous materials for preparation of electrodes for supercapacitors,lithium-ion batteries and lithium-sulfur batteries.In this paper,we have provided a state-of-the-art review on the research progress of lignocellulosic biomass as feedstock and materials for power generation and energy storage focusing on the chemistry aspects of the processes.It was recommended that process integration should be performed to reduce the cost for thermochemical and biological conversion of lignocellulose to biofuels,while efforts should be made to increase efficiency and improve the properties for biomass fuelled fuel cells and biomass derived electrodes for energy storage. | Fangqian Wang Denghao Ouyang Ziyuan Zhou Samuel JPage Dehua Liu Xuebing Zhao | 2021 | Journal of Energy Chemistry2021，30，6： | 8 |
| 18 | Cellulose conversion to polyols on supported Ru catalysts in aqueous basic solution显示文摘It is of great significance and challenge to achieve direct conversion of cellulose to specific polyols,e.g.,ethylene glycol and propylene glycol.For such selective conversion,a novel one-pot approach was studied by combination of alkaline hydrolysis and hydrogenation on supported Ru catalysts.A wide range of bases including solid bases,e.g.,Ca(OH)2 and La2O3,and phosphate buffers were examined in the cellulose reaction in water,and the cellulose conversions and polyol products depended largely on the basicity or pH values in the aqueous solutions.Ethylene glycol,1,2-propanediol,and especially 1,2,5-pentanetriol were obtained with selectivities of 15%,14% and 22%,respectively,at 38% cellulose conversion at pH 8 in phosphate buffer solution.These preliminary results provide potentials for efficient conversion of cellulose to targeted polyols by using the advantages of bases. | DENG TianYin,SUN JiYing & LIU HaiChao Beijing National Laboratory for Molecular Sciences,State Key Laboratory for Structural Chemistry of Stable and Unstable Species Green Chemistry Center,College of Chemistry and Molecular Engineering,Peking University,Beijing 100871,China | 2010 | Science China Chemistry2010，53，7： | 8 |

| 20 | A Review on the Structure and Biodegradation of Cellulose-Lignin Complexes显示文摘Cellulose is the most abundant organic macromolecule in nature and is renewable,degradable,and biocompatible.The structure of native cellulose has not yet been completely elucidated.Part of cellulose is tightly combined with lignin macromolecules through chemical bonds to form cellulose-lignin complexes(CLC).The existence of the CLC structure inhibits the complete separation of cellulose from lignocellulosic material,which not only increases the consumption of chemicals in the cooking process and causes environmental pollution,but also makes the cellulose subject to certain degradation during the deep delignification process.Therefore,elucidation of the relationship between the cellulose-lignin connection structure and performance is of great significance for efficient separation of cellulose.This article reviews the current research status of CLC and discusses the research progress regarding its biodegradation characteristics. | Yimin Xie Kai Zhang Sheng Cui Yanchao Liu | 2020 | Paper And Biomaterials2020，5，4： | 8 |
