| 1 | Catastrophe mechanism and classification of discontinuity behavior in thermal science (Ⅰ)——Fold catastrophe显示文摘The mechanism of discontinuity behavior has important significance in the study of thermal science, such as fire, combustion, explosion and heat transfer. This sort of discontinuity behavior and the catastrophe caused by system nonlinearity may be equivalently classified according to the catastrophe model promulgated by catastrophe theory. Under the conditions of uniform temperature and thermal isolation, the self-ignition behavior of a Semenov System can be viewed as a result of the fold catastrophe of the system. | XIE Zhikang, FAN Weicheng & WANG Qing’anState Key Laboratory of Fire Science, University of Science & Technology of China, Hefei 230026, China | 2000 | Chinese Science Bulletin2000，45，19： | 3 |
| 2 | Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection显示文摘Sensitive and fast detection of neutrons and gamma rays is vital for homeland security,high-energy physics,and proton therapy.Fast-neutron detectors rely on light organic scintillators,andγ-ray detectors use heavy inorganic scintillators and semiconductors.Efficient mixed-field detection using a single material is highly challenging due to their contradictory requirements.Here we report hybrid perovskites(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)that combine light organic cations and heavy inorganic skeletons at a molecular level to achieve unprecedented performance for mixed-field radiation detection.High neutron absorption due to a high density of hydrogen,strong radiative recombination within the highly confined[PbX_(6)]^(4-)layer,and sub-nanometer distance between absorption sites and radiative centers,enable a light yield of 41000 photons/MeV,detection pulse width of 2.97 ns and extraordinary linearity response toward both fast neutrons andγ-rays,outperforming commonly used fast-neutron scintillators.Neutron energy spectrum,time-of-flight based fast-neutron/γ-ray discrimination and neutron yield monitoring were all successfully achieved using(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)detectors.We further demonstrate the monitoring of reaction kinetics and total power of a nuclear fusion reaction.We envision that molecular hybridized scintillators open a new avenue for mixed-field radiation detection and imaging. | Mengling Xia Guangda Niu Linyue Liu Runlong Gao Tong Jin Pengying Wan Weicheng Pan Xianpeng Zhang Zuoxiang Xie Sam Teale Zenghua Cai Jiajun Luo Shan Zhao Haodi Wu Shiyou Chen Zhiping Zheng Qingguo Xie Xiaoping Ouyang Edward HSargent Jiang Tang | 2022 | InfoMat2022，4，9： | 2 |

| 4 | Catastrophe mechanism and classification of discontinuity behavior in thermal science (Ⅱ)——Cusp catastrophe显示文摘The catastrophe mechanisms of thermal performance characteristics of the firebox gas combustion system were analyzed from the viewpoint of catastrophe theory. The mathematical models of cusp catastrophe were established. The relationship between the thermal performance characteristics and the changing of system control variables was studied. The cusp catastrophe mechanisms of typical performance characteristics, such as kicking and lagging, and those of transition from quenching to igniting were explained. It was illustrated that discontinuity behavior of thermal systems with an 'S' motion feature curve and lagging feature may be equivalently classified according to the topology of cusp catastrophe, influenced by two groups of independent control variables. | XIE Zhikang, FAN Weicheng & WANG Qing’anState Key Laboratory of Fire Science, University of Science & Technology of China, Hefei 230026, China | 2000 | Chinese Science Bulletin2000，45，20： | 1 |

| 7 | Conductive PS inverse opals for regulating proliferation and differentiation of neural stem cells显示文摘The development of neural tissue engineering has brought new hope to the treatment of spinal cord injury(SCI).Up to date,various scaffolds have been developed to induce the oriented growth and arrangement of nerves to facilitate the repair after injury.In this work,a conductive and anisotropic inverse opal substrate was presented by modifying polystyrene(PS)inverse opal films with carbon nanotubes and then stretching them to varying degrees.The film had good biocompatibility,and neural stem cells(NSCs)grown on the film displayed good orientation along the stretching direction.In addition,benefiting from the conductivity and anisotropy of the film,NSCs differentiated into neurons significantly.These results suggest that the conductive and anisotropic PS inverse opal substrates possess value in nerve tissue engineering regeneration. | Yangnan Hu Han Zhang Hao Wei Menghui Liao Xiaoyan Chen Jiayue Xing Lian Duan Cuntu Cheng Weicheng Lu Xuechun Yang Peina Wu Huan Wang Jingdun Xie Renjie Chai | 2023 | Engineered Regeneration2023，4，2： | 0 |
| 8 | Facile construction of honeycomb-shaped porous carbon electrode materials using recyclable sodium chloride template for efficient lithium storage显示文摘Carbon materials are the preferred anode materials for Li-ion batteries.Here,we propose an easy and sustainable strategy to prepare honeycomb-shaped porous carbon(HPC)electrode materials through a process involving simple calcination and subsequent water washing by using polyvinyl-pyrrolidone(PVP)as carbon source and NaCl as pore-forming agent.A controllable cavity size and distribution of the carbon materials can be readily obtained solely by adjusting the NaCl amount.Results showed that the optimized HPC sample had a relatively uniform cavity distribution and a highly porous structure.Moreover,the special honeycomb-shaped structure was conducive to the electronic conductivity of the electrode materials,provided a short path for Li-ion transport and a wide interface with the electrolyte,and buffered the volume change of active materials.The special honeycomb-shaped structure was also maintained well after long cycles,which improved electrode stability.When used as anode materials for Li-ion batteries(LIBs),the sample demonstrated excellent cycling stability and rate performance,with a high specific capacity of 230 mA hg^-1 and a reversible capacity of 197 mA hg^-1,after 1200 cycles at 2 C.Overall,we introduced a simple strategy for the potential mass production of porous carbon materials for LIBs. | FANG ShiQing HE HaoXuan YU YingHui LI Xiao XIE WeiCheng LI Wei JIN LuQiao YANG ZhenYu CAI JianXin | 2020 | Science China(Technological Sciences)2020，63，10： | 0 |
