| 1 | Micro-interfaces modulation by UV-ozone substrate treatment for MPEA vapor fluorescence detection显示文摘Drug abuse directly endangers human health and social security,hence its sensitive and rapid detection is vitally important.In recent years,organic film-based fluorescent sensing technology has attracted more and more attention in the detection of drugs and explosives due to its advantages of simple operation and rapid detection.For film-based fluorescent sensors,in addition to sensitive materials,the surface morphology of the film is also an important factor affecting the performance.In previous studies,the regulation of surface morphology mainly depends on concentration changes or complex templates.Here,a novel fluorescent polymer probe was designed and synthesized,and a simple and efficient ultraviolet(UV)-ozone substrate treatment method is used to adjust their surface morphology.The results show that film has an excellent fluorescence enhancement effect upon exposure to methylphenethylamine(MPEA,a simulant of methamphetamine)vapor.The sensing effect of the film is significantly improved after UV-ozone substrate treatment,and the limit of detection was decreased by 10.4 times from 2.59 to 0.25 ppm.Further experiments show that the sensing performance of other fluorescent probe can also be improved by the UV-ozone substrate treatment.This convenient and general method may become a very effective approach to improve the performance of film-based fluorescent sensors. | Bin Li Keke Li Wei Xu Mingzhu Yan Jianhao Zhao Wukun Zhang Mingshuai Yuan Yanyan Fu Qingguo He Jiangong Cheng | 2023 | Nano Research2023，16，3： | 0 |
| 2 | Building Better Full Manganese‑Based Cathode Materialsfor Next‑Generation Lithium‑Ion Batteries显示文摘Lithium-manganese-oxides have been exploited as promising cathode materials for many years due to their environmental friendliness,resource abundance and low biotoxicity.Nevertheless,inevitable problems,such as Jahn-Teller distortion,manganese dissolution and phase transition,still frustrate researchers;thus,progress in full manganese-based cathode materials(FMCMs)has been relatively slow and limited in recent decades.Recently,with the fast growth of vehicle electrification and large-scale energy-storage grids,there has been an urgent demand to develop novel FMCMs again;actually,new waves of research based on FMCMs are being created.Herein,we systematically review the history of FMCMs,correctly describe their structures,evaluate the advantages and challenges,and discuss the resolution strategies and latest developments.Additionally,beyond FMCMs,a profound discussion of current controversial issues,such as oxygen redox reaction,voltage decay and voltage hysteresis in Li_(2)MnO_(3)-based cathode materials,is also presented.This review summarizes the effectively optimized approaches and offers a few new possible enhancement methods from the perspective of the electronic-coordination-crystal structure for building better FMCMs for next-generation lithium-ion batteries. | Jin Song Hangchao Wang Yuxuan Zuo Kun Zhang Tonghuan Yang Yali Yang Chuan Gao Tao Chen Guang Feng Zewen Jiang Wukun Xiao Tie Luo Dingguo Xia | 2023 | Electrochemical Energy Reviews2023，6，1： | 0 |
