| 1 | Preparation of sulfoaluminate cementitious material using harmful titanium gypsum:material properties and heavy metal immobilization characteristics显示文摘The production of titanium dioxide(a necessary industrial color additive)can generate massive amount of titanium gypsum,a hard-to-treat solid waste.Diverse metallic impurities,heavy metals and reddish color in titanium gypsum make it difficult to be used in building materials like other by-product gypsums.As a result,most of titanium gypsum in China is just stored and has caused serious environmental issues.In this study,titanium gypsum,which contained high contents of impurities and heavy metals,was synergistically used with other three solid wastes to prepare sulfoaluminate cementitious material(SACM)for the first time.The mass proportion of titanium gypsum in the raw materials exceeded 25%.The chemical,mechanical and heavy metal leaching characteristics of this solid waste-based SACM were tested via XRD,XRF,ICP-OES,etc.The main components and metallic impurities of titanium gypsum could be transformed to the components of the main mineral of SACM,ye’elimite.The compressive strength of the prepared SACM reached 38.2,59.7 and 95.8 MPa at 1-day,3-day,and 28-day hydration,respectively,indicating the features of rapidly hardening and high strength.Importantly,the solid waste-based SACM could effectively solidify the heavy metals contained in titanium gypsum and other raw material during thje hydration process.The retention ratio of total Cr reached 97.5%,and other heavy metals were almost not detected in the leachate of SACM.This study provided a feasible approach to utilize titanium gypsum to produce high-performance,green building material,and might promote the massive utilization of this solid waste. | Jingwei Li Wenlong Wang Dong Xu Xujiang Wang Yanpeng Mao | 2020 | Waste Disposal and Sustainable Energy2020，2，2： | 5 |
| 2 | Technology and engineering application of cross area HVDC interconnection system high-precision simulation modeling based on ADPSS显示文摘In recent years, a large number of high voltage direct current(HVDC) transmission projects have been connected to AC systems. This has started to have an impact on AC/DC hybrid power grids, particularly receiving terminal power grids. An HVDC system is a large-scale power electronic integrated nonlinear system, and it includes a primary system and a control and protection system. Hence, the precision and degree of detail of HVDC systems directly affect the actual effect of simulation. In recent years, in the case of the normal operation and failure of AC power grids, the abnormal fluctuation and even locking of HVDC systems caused by the inappropriate strategies of the control and protection system component have strongly affected power grids. This has significantly affected the safety and stability of receiving power grids and normal operation. In this study, the actual engineering HVDC control logic provided by a manufacturer is analyzed and simulated based on the user defined component library of the ADPSS electromagnetic transient calculation program, and an HVDC control model based on an actual system is established. The accuracy of the DC control custom model based on ADPSS is verified through the simulation of an actual power grid. | Weijie Zheng Jianfeng Yan Xujiang Chen Shuwen Xu Yalou Li | 2018 | Global Energy Interconnection2018，1，5： | 3 |
| 3 | 3D bioprinting of a biomimetic meniscal scaffold for application in tissue engineering显示文摘Appropriate biomimetic scaffolds created via 3D bioprinting are promising methods for treating damaged menisci.However,given the unique anatomical structure and complex stress environment of the meniscus,many studies have adopted various techniques to take full advantage of different materials,such as the printing combined with infusion,or electrospining,to chase the biomimetic meniscus,which makes the process complicated to some extent.Some researchers have tried to tackle the challenges only by 3D biopringting,while its alternative materials and models have been constrained.In this study,based on a multilayer biomimetic strategy,we optimized the preparation of meniscus-derived bioink,gelatin methacrylate(GelMA)/meniscal extracellular matrix(MECM),to take printability and cytocompatibility into account together.Subsequently,a customized 3D bioprinting system featuring a dual nozzle+multitemperature printing was used to integrate the advantages of polycaprolactone(PCL)and meniscal fibrocartilage chondrocytes(MFCs)-laden GelMA/MECM bioink to complete the biomimetic meniscal scaffold,which had the best biomimetic features in terms of morphology and components.Furthermore,cell viability,mechanics,biodegradation and tissue formation in vivo were performed to ensure that the scaffold had sufficient feasibility and functionality,thereby providing a reliable basis for its application in tissue engineering. | Zhou Jian Tian Zhuang Tian Qinyu Peng Liqing Li Kun Luo Xujiang Wang Diaodiao Yang Zhen Jiang Shuangpeng Sui Xiang Huang Jingxiang Liu Shuyun Hao Libo Tang Peifu Yao Qi Guo Quanyi | 2021 | Bioactive Materials2021，6，6： | 3 |

| 5 | Effects of Portland cement addition on the early-age properties of solid-waste-based sulphoaluminate cement显示文摘This paper investigated the effects of different proportions of Portland cement addition(0-20%)on the setting time and early-age strength of solid-waste-based sulphoaluminate cement.The mechanism of hydration process was analyzed by X-ray diffraction(XRD)technology.It was found that the incorporation of Portland cement could reduce the early-age strength of the composite cement,and shorten the setting time.When the Portland cement reached 20%,the early-age strength of the composite cement was the lowest and the setting time was the shortest.The XRD analysis demonstrated that the addition of Portland cement could accelerate the hydration process of the composite cement,and the more the Portland cement was added,the faster the hydration process of the composite cement was observed.The main reason is that the addition of Portland cement could increase the alkalinity of the composite cement and promote the hydration of anhydrous calcium sulphoaluminate.This study provides an important reference for the production of solid-waste-based composite cement. | Kun Wang Xujiang Wang Jingwei Li Wenlong Wang | 2020 | Waste Disposal and Sustainable Energy2020，2，1： | 2 |

| 7 | Electric Vehicle Charging Simulation Framework Considering Traffic,User,and Power Grid显示文摘The traffic and user have significant impacts on the electric vehicle(EV)charging load but are not considered in the existing research.We propose a novel integrated simulation framework considering the traffic,the user,and power grid as well as the EV traveling,parking and charging based on cellular automaton(CA).The traffic is modeled by the traffic module of the proposed framework based on CA,while the power grid and user are modeled in the EV charging module.The traffic flow,user’s charging preference,user’s charging satisfaction,and the total supply capability(TSC)in the surveyed region are considered in the proposed framework.Two cases are carried out to show the interactions between the user and power grid.It is shown that the proposed framework can accurately simulate the interactions among traffic situation,user's behavior and TSC,which are significantly lacking in the existing research.The proposed framework is scalable in considering additional interrelated elements. | Weicheng Liu Xujiang Shi Jianfeng Zhao Xiao-Ping Zhang Ying Xue | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，3： | 1 |

| 11 | Scalable van der Waals graphene films for electro-optical regulation and thermal camouflage显示文摘Graphene exhibits enormous advantages in mid-infrared(MIR)regulation because of the active control,precise regulation,and large modulation depth.Such graphene films are prepared via chemical vapor deposition(CVD)or reduction,which cannot realize large-scale production and limit the applications.Graphene films with van der Waals(vdW)structure enable excellent mechanical and electrical performance for flexible electrodes and electronics and might be a candidate for MIR regulation.However,current techniques for preparing vdW graphene films require binder or solution assistance,resulting in chemical residues and performance degradation.Here,a new strategy for preparing large-area vdW graphene films by simple mechanical adhesion without any additives was proposed.By selecting the carriers and substrates with proper fracture energies,graphene nanosheets can be transferred from one polymer to another with a layer-by-layer structure.The obtained graphene films possess desired thickness and comparable electrical conductivity(92.8±4.6 ohm sq–1)with those by chemical vapor deposition.They are of high compactness even for ions to intercalate reversibly,which exhibit excellent electrochemical activity and electro-optical regulation capability,effectively suppressing 90%thermal radiation.This strategy can be extended to prepare high-performance vdW graphene films on various polymer substrates and used for sustainable and smart electro-optical applications. | Ziqi Li Xujiang Chao Andrew Balilonda Wei Chen | 2023 | InfoMat2023，5，6： | 1 |

| 15 | Influencing factors and optimization on mechanical performance of solid waste-derived rapid repair mortar显示文摘There is a great demand for high performance rapid repair mortar(RRM)because of the wide use of cement concrete.Solid-waste-based sulfoaluminate cement(WSAC)is very suitable as a green cementitious material for repair materials because of its characteristics of high early-age strength and short setting time.However,the influence and optimization of various factors of WSAC-based RRM,such as water-to-RRM ratio,binder-to-sand ratio and additives,as well as the further solid waste replacement of aggregate,remain to be studied.This paper comprehensively studied the influence of the above factors on the performance of WSAC-based RRM and obtained a green high-performance RRM by optimizing these factors.The experimental results showed that the early and late strength of the obtained RRM is excellent,and the setting time and fluidity are appropriate,which reflected good mechanical properties and construction performance.Ordinary Portland cement(OPC)doping could not improve RRM strength.It was feasible to prepare RRM with gold tailing sand replacing part of the quartz sand.This paper provides data and a theoretical basis for the preparation of high-performance RRM based on solid waste,expanding the high value utilization of solid waste,which is conducive to the development of a low carbon society. | Jingwei Li Xiangshan Hou Aiguang Jia Xin Xiao Xujiang Wang Yonggang Yao Ziliang Zhang Wenlong Wang | 2023 | Waste Disposal and Sustainable Energy2023，5，2： | 0 |
| 16 | Integrating the second near-infrared fluorescence imaging with clinical techniques for multimodal cancer imaging by neodymiumdoped gadolinium tungstate nanoparticles显示文摘Second near-infrared(NIR-II)fluorescence imaging is a recently emerged technique and is highly useful for accurate diagnosis of cancer.Although a diverse array of fluorescent nanomaterials have been developed to enable NIR-II fluorescence in various situations,they normally fail to unify the clinical techniques,such as computed tomography(CT)and magnetic resonance imaging(MRI).Therefore,exploiting multimodal agents to integrate the newly emerged NIR-II fluorescence and traditional clinical techniques would be of key significance.Here,we report a rational fabrication of neodymium(Nd)-doped gadolinium tungstate nanoparticles(NPs)that are subsequentially decorated with a hydrophilic layer and demonstrate that they can achieve the harmonious integration of NIR-II fluorescence imaging,CT,and MRI.The NIR-II fluorescence emission was activated by an incident light with discrete wavelength ranging from 250 to 810 nm.NIR-II fluorescence-CT-MRI associated trimodal imaging was subsequently demonstrated for breast cancer by an 808 nm laser,along with the estimation of NIR-II fluorescence imaging for cervical cancer.The integration of newly emerged and traditional clinical imaging techniques highlights the huge potential of rare-earth-doped NPs for multimodal imaging of different types of cancer. | Xujiang Yu Aodenggerile Zhao Jiang Jianliang Shen Zhiqiang Yan Wanwan Li Huibin Qiu | 2021 | Nano Research2021，14，7： | 0 |
