| 1 | Synthesis and combined properties of novel fluorinated cationic surfactants derived from hexafluoropropylene dimer显示文摘Three novel fluorinated cationic surfactants were prepared by adopting perfluoro-2-methyl-2-pentene as raw substrate. The as-obtained fluorinated cationic surfactants exhibited excellent surface properties, all of them can reduce the surface tension of water to below 20.00 mN/m at the critical micelle concentrations(CMC). The incorporation of SDS, AOS, APG or LAB into 2-(4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis(trifluoromethyl)pentyl)benzamido)-N,N-dimethylethana-mine oxide 4 a could generate much lower CMC and surface tension value at the CMC than individual 4 a. Especially, the surface tension values of that combined APG/4 a can be reduced to 17.31 mN/m. The excellent surface activities and their remarkable compatibility to various types of hydrocarbon surfactants make them as sustainable alternatives to PFOA(perfluorooctanoic acid, C_7 F_(15)CO_2 H) and PFOS(perfluorooctane sulphonate,C_8 F_(17)SO_3 X, with X = K, Na, H). | Chao Lin Renming Pan Ping Xing Biao Jiang | 2018 | Chinese Chemical Letters2018，29，11： | 2 |

| 4 | Design and synthesis of the novel branched fluorinated surfactant intermediates with CF_3CF_2CF_2C(CF_3)_2 group显示文摘Perfluorooctanoic acid(PFOA) or perfluorooctane sulphonate(PFOS) was one of the most prominent fluorosurfactants and applied widely in firefighting and daily chemical, etc. However, these surfactants have recently been identified as toxic and undegradability in the environment. Developing an efficient approach to environment-friendly fluorosurfactants is essential. A fluorocarbon branched chain strategy was adopted to develop/PFOS substitutes. A series of intermediates of novel branched fluorinated surfactants with CF_3 CF_2CF_2C(CF3)_2 group were synthesized from perfluoro-2-methyl-2-pentene. All the steps were mild, easy-handled and cheap. It is expected to be a very significant direction for the development of non-bioaccumulable alternatives of PFOA or PFOS. | Ding Zhang Min Sha Renming Pan Xiangyang Lin Ping Xing Biao Jiang | 2019 | Chinese Chemical Letters2019，30，3： | 1 |
| 5 | Optimal guaranteed cost control for an uncertain discrete T-S fuzzy system with time-delay显示文摘This paper considers the guaranteed cost control problem for a class of uncertain discrete T-S fuzzy systems with time delay and a given quadratic cost function.Sufficient conditions for the existence of such controllers are derived based on the linear matrix inequalities(LMI) approach by constructing a specific nonquadratic Lyapunov-Krasovskii functional and a nonlinear PDC-like control law.A convex optimization problem is also formulated to select the optimal guaranteed cost controller that minimizes the upper bound of the closed-loop cost function.Finally,numerical examples are presented to demonstrate the effectiveness of the proposed approaches. | Renming WANG Thierry Marie GUERRA Juntao PAN | 2009 | 控制理论与应用(英文版)2009，7，2： | 0 |

| 7 | Synthesis and Surface Activity Study of a Novel Branched Fluorinated Anion Surfactant with CF_(3)CF_(2)CF_(2)C(CF_(3))_(2) Group显示文摘A novel branched fluorinated anion surfactant 4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis-trifluoromethyl-pentyl)-benzene lithium phosphonate was successfully synthesized via a four-step route using perfluoro-2-methyl-2-pentene as starting material.The surface activity was investigated.The result showed that the cmc value of the surfactant in water is about 1.5×10^(−2) mol/L at 298 K and the surface tension of the aqueous solution is 19.2 mN/m at the cmc. | Min Sha Renming Pan Lewu Zhan Ping Xing Biao Jiang | 2014 | Chinese Journal of Chemistry2014，32，10： | 0 |
| 8 | Strong coupling between a plasmon mode and multiple different exciton states显示文摘Strong coupling between plasmons and multiple different exciton states(MESs)enables the creation of multiple hybrid polariton states under ambient conditions.These hybrid states possess unique optical properties different from those of their separate identities,making them ideal candidates for exploiting room-temperature multimode hybridization and multiqubit operation.In this study,we revealed the static spectral response properties of plasmon-MES strong coupling via a fully quantum mechanics approach.These theoretical predictions were experimentally demonstrated in plasmonic nanocavities containing two and three different exciton species.Additionally,the dynamical absorption processes of such strong coupling systems were investigated,and results indicated that the damping of the hybrid polariton states induced by the strong coupling could be markedly modulated by the acoustic oscillations from the plasmonic nanocavities.Our findings contribute a theoretical approach for accurately describing the plasmon-MES interactions and a platform for developing the high-speed active plasmonic devices based on multiqubit strong coupling. | Junjun Ye Yatao Pan Guanghui Liu Wei Li Renming Liu Ming Geng Zhixiang Liu Zhen Chi Xia Ran Yanmin Kuang Yulu He Lijun Guo | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，4： | 0 |
