| 1 | Properties and Applications of Bamboo Fiber—A Current-State-of-the Art显示文摘Fibers are used in many forms in engineering applications–one of the most common being used as reinforcement.Due to its renewable short natural growth cycle and abundance of bamboo resources,bamboo fiber has attracted attention over other natural fibers.Bamboo fiber has a complex natural structure but offers excellent mechanical properties,which are utilized in the textile,papermaking,construction,and composites industry.However,bam-boo fibers can easily absorb moisture and are prone to corrosion limiting their use in engineering applications.Therefore,a better understanding of bamboo fiber is particularly important.This paper reviews all existing research on the mechanical characterization of bamboo fiber with an emphasis on the extraction and treatment techniques,and their effect on relevant properties.The chemical composition of bamboo fibers has also been thoroughly investigated and presented herein.Current applications and future opportunities for bamboo fibers in various fields have been presented with a focus on research needs.This work can serve as a reference for future research on bamboo fiber. | Chen Chen Haitao Li Assima Dauletbek Feng Shen David Hui Milan Gaff Rodolfo Lorenzo Ileana Corbi Ottavia Corbi Mahmud Ashraf | 2022 | Journal of Renewable Materials2022，10，3： | 3 |
| 2 | Review on Connections for Original Bamboo Structures显示文摘Bamboo is a green construction material in line with sustainable development strategies.The use of raw bamboo in architecture has existed since ancient times.In the long development years of original bamboo buildings,many areas in the world gradually formed unique bamboo buildings,which have become an important local cultural feature.For building structures,joints are the key to ensure structural load transfer.Because of hollow and thin-walled material property of bamboo,the connection in raw bamboo buildings has always been a major difficulty and problem in the application of bamboo,which seriously hinders the development of original bamboo structures.In order to promote the use of raw bamboo,two traditional connection methods in raw bamboo structures are described in this paper firstly,with the advantages and disadvantages of the two methods pointed out.Also,research progress on four categories of raw bamboo building joints is described namely,bolt joints,steel member joints,filler reinforced joints and other types of joints.This work can provide a reference for future research and engineering applications. | Chaokun Hong Haitao Li Rodolfo Lorenzo Gang Wu Ileana Corbi Ottavia Corbi Zhenhua Xiong Dong Yang Huizhong Zhang | 2019 | Journal of Renewable Materials2019，7，8： | 3 |
| 3 | A Review of Basic Mechanical Behavior of Laminated Bamboo Lumber显示文摘Over the past decade,the physical and mechanical performances of laminated bamboo lumber(LBL)–a bamboo-based structural material,have been extensively studied using experimental,analytical,and numerical approaches.This paper presents a review of existing knowledge in the literature about the mechanical properties of LBL.The paper involved the review of the response of LBL to different types of loading such as tension,bending,compres-sion,and shear.Based on results of the literature reviewed,the strength of LBL parallel to grain was 90–124 MPa with MOE of 10700 MPa in tension,29.55–72.60 MPa,and MOE of 8396–11022 MPa in compression,63.87–128.4 MPa,and MOE of 8320–10912 MPa in bending,and 7.15–17.5 MPa in shear.The average strength of LBL was similar and in some cases exceeded the average values of bamboo-or wood-based materials,while the variability of its mechanical parameters was lower.The variability in strength values of LBL was affected by bamboo species,density and thickness of bamboo strips,growth portion,type of treatment,strips arrange-ments,and type of adhesive which in turn calls for classification of LBL by strength grades,degree of hardness,the capability of impregnation and penetration,as well as by areas of application in construction.The study pro-vided and discussed concluding observations,the current research gap,and future research directions on the mechanical properties of LBL. | Assima Dauletbek Haitao Li Rodolfo Lorenzo Ileana Corbi Ottavia Corbi Mahmud Ashraf | 2022 | Journal of Renewable Materials2022，10，2： | 2 |
| 4 | A Review of Fibre Reinforced Polymer (FRP) Reinforced Concrete Composite Column Members Modelling and Analysis Techniques显示文摘The use of fibre-reinforced polymer(FRP)to confine concrete columns improves the strength and ductility of the columns by reducing passive lateral confinement pressure.Many numerical and analytical formulations have been proposed in the literature to describe the compressive behaviour of FRP confined concrete under both monotonic and cyclic loads.However,the efect of a stress/strain level in the columns has not been well defined because of the lack of well-defined strategies of modeing and oversimplification of the model.This paper reviews the existing FRP combinations and the available numerical and analytical methods to determine the effectiveness of the adopted method.An effort has been made to examine the usage of FRP materials in column applications in exist-ing building regimes and highlights the possible future scopes to improve the use of FRP confined concrete in civil applications. | Mahdi Hosseini Bingyu Jian Haitao Li Dong Yang Ziang Wang Zixian Feng Feng Shen Jian Zhang Rodolfo Lorenzo Ileana Corbi Ottavia Corbi | 2022 | Journal of Renewable Materials2022，10，12： | 1 |

| 13 | Slenderness Ratio Effect on the Eccentric Compression Performance of Chamfered Laminated Bamboo Lumber Columns显示文摘Eccentric compression tests on 15 chamfered laminated bamboo lumber(LBL)columns with a height ranging from 600 to 3000 mm were conducted in order to study the eccentric mechanical performance.The failure of all specimens was caused by the crack of bamboo fiber in the tensile region.When the ultimate strength was reached,except specimens with a height of 600 mm,all other specimens could bear large deformation,showing good ductility.The lateral displacements of the specimens under eccentric compression were approximately para-bolic in the direction of column height.The ultimate bending moment of LBL columns with different slenderness ratios under compression with the same initial eccentricity was a fixed value.The relationship between ultimate capacity,axial displacement,lateral displacement,and slenderness ratio was analyzed based on test results.It was found that the plane section assumption could be used to express the stress and strain distribution of chamfered LBL columns under eccentric compression.A method for calculating the ultimate bearing capacity was proposed using a constitutive model based on the Ramberg-Osgood relation and the empirical formula for calculating the ultimate capacity was given on the basis of the former research as well as the test results in this paper. | Ke Zhou Haitao Li Assima Dauletbek Dong Yang Zhenhua Xiong Rodolfo Lorenzo Kun Zhou Ileana Corbi Ottavia Corbi | 2022 | Journal of Renewable Materials2022，10，1： | 1 |

| 16 | Lateral Performance for Wood-Frame Shear Walls–A Critical Review显示文摘Wood is a green material in line with the sustainable development strategy.From the excellent performance of engineering wood products,modern wood structures represented by light wood structures have gained more development opportunities.As an indispensable part of light wood structure systems,the wood-frame shear wall plays a vital role in the bearing capacity and earthquake resistance of light wood structure systems.This paper is focused on a review of the lateral performance of wood-frame shear walls and classifies the influencing factors in relevant experimental research into three categories,including internal factors such as shear wall structure,external factors such as test scheme,and other factors of material production and test process.Finally,the research prospects in this field were introduced based on the summary of the research status.This work can be a reference for further research on the lateral performance of wood-frame shear walls. | Wei Xu Ottavia Corbi Seithati Mapesela Yue Chen Milan Gaff Haitao Li | 2023 | Journal of Renewable Materials2023，11，5： | 0 |
| 17 | Nodes Effect on the Bending Performance of Laminated Bamboo Lumber Unit显示文摘This research studied the ultimate bearing capacity of laminated bamboo lumber(LBL)unit and thereby calculated the maximum bending moment.The load-displacement chart for all specimens was obtained.Then the flexural capacity of members with and without bamboo nodes in the middle section was coMPared.The bending experiment phenomenon of LBL unit was concluded.Different failure modes of bending components were analysed and concluded.Finally,the bending behaviour of LBL units is coMPared with other bamboo and timber products.It is shown that the average ultimate load of BS members is 866.1 N,the average flexural strength is 101 MPa,the average modulus of elasticity is 8.3 GPa,and the average maximum displacement is 17.02 mm.The average ultimate load of BNS members is 1008.1 N,the average flexural strength is 118.02 MPa,the average modulus of elasticity is 9.9 GPa,and the average maximum displacement is 18.26 mm.Laminated bamboo lumber(LBL)unit without bamboo nodes(BNS)has relatively higher flexural strength coMPared with LBL unit with bamboo nodes(BS).The presence of bamboo nodes reduces the strength of the entire structure.Three failure modes were concluded for BS members,and two failure modes were observed for BNS members during the experimental process.According to a coMParison between the LBL unit and other products,the flexural strength and bending modulus of elasticity of the LBL unit are similar as bamboo scrimber and raw bamboo components,which is much higher than timber components. | Yiwei Xuan Haitao Li Zhemin Bei Zhenhua Xiong Rodolfo Lorenzo Ileana Corbi Ottavia Corbi | 2021 | Journal of Renewable Materials2021，9，6： | 0 |
| 18 | Ritanserin blocks CaV1.2 channels in rat artery smooth muscles: electrophysiological, functional, and computational studies显示文摘CaV1.2 channel blockers or 5-HT2 receptor antagonists constitute effective therapy for Raynaud’s syndrome.A functional link between the inhibition of 5-HT2 receptors and CaV1.2 channel blockade in arterial smooth muscles has been hypothesized.Therefore,the effects of ritanserin,a nonselective 5-HT2 receptor antagonist,on vascular CaV1.2 channels were investigated through electrophysiological,functional,and computational studies.Ritanserin blocked CaV1.2 channel currents(ICa1.2)in a concentration-dependent manner(Kr=3.61µM);ICa1.2 inhibition was antagonized by Bay K 8644 and partially reverted upon washout.Conversely,the ritanserin analog ketanserin(100µM)inhibited ICa1.2 by^50%.Ritanserin concentration-dependently shifted the voltage dependence of the steady-state inactivation curve to more negative potentials(Ki=1.58µM)without affecting the slope of inactivation and the activation curve,and decreased ICa1.2 progressively during repetitive(1 Hz)step depolarizations(use-dependent block).The addition of ritanserin caused the contraction of single myocytes not yet dialyzed with the conventional method.Furthermore,in depolarized rings,ritanserin,and to a lesser extent,ketanserin,caused a concentration-dependent relaxation,which was antagonized by Bay K 8644.Ritanserin and ketanserin were docked at a region of the CaV1.2α1C subunit nearby that of Bay K 8644;however,only ritanserin and Bay K 8644 formed a hydrogen bond with key residue Tyr-1489.In conclusion,ritanserin caused in vitro vasodilation,accomplished through the blockade of CaV1.2 channels,which was achieved preferentially in the inactivated and/or resting state of the channel.This novel activity encourages the development of ritanserin derivatives for their potential use in the treatment of Raynaud’s syndrome. | Fabio Fusi Alfonso Trezza Giampietro Sgaragli Ottavia Spiga Simona Saponara Sergio Bova | 2020 | Acta Pharmacologica Sinica2020，41，9： | 0 |

| 20 | Complexation of As(Ⅲ)by phosphonate ligands in aqueous fluids:Thermodynamic behavior,chemical binding forms and sequestering abilities显示文摘In recent years,the contamination of water by arsenic reached alarming levels in many countries of the world,attracting the interest of many researchers engaged in testing methodologies able to remove this harmful pollutant.An important aspect that must be taken into consideration is the possibility to find arsenic in different chemical forms which could require different approaches for its removal.At this aim,a speciation analysis appears to be crucial for better understanding the behavior of arsenic species in aqueous solutions,especially in presence of compounds with marked chelating properties.Phosphonates can be identified as good sequestering agents and,at this purpose,this manuscript intends to investigate the interaction of As(Ⅲ)with three phosphonic acids derived from nitrilotriacetic acid(NTA)by replacements of one(N-(Phosphonomethyl)iminodiacetic acid,NTAP),two(N,N-Bis-(phosphonomethyl)glycine,NTA2P)and three(Nitrilotri(methylphosphonic acid),NTA3P)carboxylic groups with the same number of phosphonate groups.An in-depth potentiometric and calorimetric investigation allowed to determine speciation models featured by simple ML,MLH i and ML(OH)species.A complete thermodynamic characterization of the systems is reported together with the definition of coordination mode by mass spectrometry measurements.On the light of the speciation models,the possibility of using these ligands in arsenic removal techniques was assessed by determining the pL 0.5(the concentration of ligand able to remove the 50%of metal ion present in trace).All ligands show a good sequestering ability,in particular under the conditions of fresh water,following the trend NTA3P>NTA2P>NTAP. | Donatella Chillè Donatella Aiello Giuseppa Ida Grasso Ottavia Giuffrè Anna Napoli Carmelo Sgarlata Claudia Foti | 2020 | Journal of Environmental Sciences2020，32，8： | 0 |
