| 1 | Effect of 1-butyl-3-methylimidazolium tetrafluoroborate on the formation rate of CO_2 hydrate显示文摘The effect of the addition of 1-butyl-3-methylimidazolium tetrafluoroborate ([C4mim][BF4]) on the formation rates of CO2 hydrates was investigate. The isothermal and isobaric methods were used to measure the formation rates of CO2 hydrates. As compared to those of pure water, the data of phase equilibrium changed greatly. The effects of pressure, temperature, and the concentration of [C4mim][BF4] aqueous solution on the formation rates of CO2 hydrates were investigated. With a constant concentration of [C4mim][BF4], the rate of gas consumption was enhanced with the lowering of experimental temperature. However, a decrease in pressure exerted an opposite effect on the rate of gas consumption. Moreover, the addition of [C4mim][BF4] raised the equilibrium pressure of hydrate formation at the same temperature. | Qi Chen Yong Yu Peng Zeng Wei Yang Qianqing Liang Xiaoming Peng Yansheng Liu Yufeng Hu | 2008 | Journal of Natural Gas Chemistry2008，17，3： | 5 |
| 2 | Absolute Ruin Problems for the Risk Processes with Interest and a Constant Dividend Barrier显示文摘In this paper,the absolute ruin in the compound Poisson risk model with interest and a constant dividend barrier is investigated.First,integro-differential equations satisfied by the expected discounted dividend payments are derived.The explicit expressions are obtained when the individual claim size is expo-nential distributed.Second,the moment generating function of the discounted dividends is considered,and integro-differential equations satisfied by the moment generating function of the discounted dividends are derived.Third,by a 'differential' argument,the time to recovery to zero from a given negative surplus is considered.Finally,how long it takes for the surplus process to reach the dividend barrier is discussed. | YUAN Haili HU Yijun QIN Qianqing | 2011 | Wuhan University Journal of Natural Sciences2011，16，3： | 1 |
| 3 | High-performance all-solution-processed inverted quantum dot light-emitting diodes enabled by water treatment显示文摘All-solution-processed inverted quantum dot(QD)light-emitting diodes(QLEDs)with transparent bottom cathodes can be directly connected to the n-type thin-film transistors,offering a feasible solution for low-cost active matrix-driven QD displays.However,the subsequent solution-deposition of the hole-transporting layer destroys the underneath QD films,resulting in largely deteriorated device performance.Various strategies have been implemented to prevent QD film from dissolution,but all at a heavy cost of device performance suffering from either reduced efficiency or increased driving voltage.Here,a facile and effective water-treatment approach for QD film to fabricate inverted QLEDs through all solution processing is reported.The water treatment substitutes the long-chain oleate ligands with hydroxyl groups,resulting in significantly improved non-polar solvent resistance of the QD films.Importantly,the QD films reserve their excellent photoluminescence efficiency after water treatment.With the water-treated QD film as the emissive layer,all-solution-processed inverted red QLED with a peak external quantum efficiency of 19.6%,a turn-on voltage of 1.8 V,and a T50 operational lifetime of 150,000 h at 100 cd·m^(-2) was achieved.Furthermore,efficient and low-voltage-driven green and blue QLEDs can also be prepared with this method.This work provides a feasible strategy for the fabrication of high-performance all-solution-processed inverted QLEDs,paving the way toward achieving QLEDs by all ink-jet printing. | Qianqing Hu Junjie Si Desui Chen Xiaoming Hao Rui Xu Yihang Du Zhuopeng Du Xinquan Gong Hong Zhao Peiqing Cai Qi Ai Xin Yao Yu Yan Zenan Zhang Muzhi Cai Wei Liu Yongyin Kang Zugang Liu | 2023 | Nano Research2023，16，7： | 0 |
