| 1 | From structural ceramics to 2D materials with multi-applications:A review on the development from MAX phases to MXenes显示文摘MAX phases(Ti_(3)SiC_(2),Ti_(3)AIC_(2),V_(2)AlC,TiqAlN_(3),etc.)are layered ternary carbides/nitrides,which are generally processed and researched as structure ceramics.Selectively removing A layer from MAX phases,MXenes(Ti_(3)C_(2),V_(2)C,Mo_(2)C,etc.)with two-dimensional(2D)structure can be prepared.The MXenes are electrically conductive and hydrophilic,which are promising as functional materials in many areas.This article reviews the milestones and the latest progress in the research of MAX phases and MXenes,from the perspective of ceramic science.Especially,this article focuses on the conversion from MAX phases to MXenes.First,we summarize the microstructure,preparation,properties,and applications of MAX phases.Among the various properties,the crack healing properties of MAX phase are highlighted.Thereafter,the critical issues on MXene research,including the preparation process,microstructure,MXene composites,and application of MXenes,are reviewed.Among the various applications,this review focuses on two selected applications:energy storage and electromagnetic interference shielding.Moreover,new research directions and future trends on MAX phases and MXenes are also discussed. | Aiguo ZHOU Yi LIU Shibo LI Xiaohui WANG Guobing YING Qixun XIA Peigen ZHANG | 2021 | Journal of Advanced Ceramics2021，10，6： | 4 |
| 2 | Recent progress on green electromagnetic shielding materials based on macro wood and micro cellulose components from natural agricultural and forestry resources显示文摘Recent research efforts in the field of electromagnetic interference shielding(EMI)materials have focused on biomass as a green and sustainable resource.More specifically,wood and cellulose nano fiber(CNF)have many advantages,some of which include lightweight,porosity,widespread availability,low cost,and easy processing.These favorable properties have led researchers to consider these types of biomass as an EMI shielding material with great potential.At present,while many excellent published works in EMI shielding materials have investigated wood and CNF,this research area is still new,compared with non-biomass EMI shielding materials.More specifically,there is still a lack of in-depth research and summary on the preparation process,pore structure regulation,component optimization,and other factors affecting the EMI shielding of wood and CNF based EMI shielding materials.Thus,this review paper presents a comprehensive summary of recent research on wood and CNF based EMI shielding materials in recent three years in terms of the preparation methods,material structure design,component synergy,and EMI mechanism,and a forward future perspective for existing problems,challenges,and development trend.The ultimate goal is to provide a comprehensive and informative reference for the further development and exploration of biomass EMI shielding materials. | Chuanyin Xiong Tianxu Wang Yongkang Zhang Meng Zhu Yonghao Ni | 2022 | Nano Research2022，15，8： | 1 |
