| 1 | Temperature sensitivity of organic compound destruction in SCWO process显示文摘To study the temperature sensitivity of the destruction of organic compounds in supercritical water oxidation process(SCWO), oxidation effects of twelve chemicals in supercritical water were investigated. The SCWO reaction rates of different compounds improved to varying degrees with the increase of temperature, so the highest slope of the temperature-effect curve(imax) was defined as the maximum ratio of removal ratio to working temperature. It is an important index to stand for the temperature sensitivity effect in SCWO. It was proven that the higher imax is, the more significant the effect of temperature on the SCWO effect is. Since the high-temperature area of SCWO equipment is subject to considerable damage from fatigue, the temperature is of great significance in SCWO equipment operation. Generally, most compounds(imax > 0.25) can be completely oxidized when the reactor temperature reaches 500℃. However, some compounds(imax > 0.25) need a higher temperature for complete oxidation, up to 560℃. To analyze the correlation coefficients between imax and various molecular descriptors, a quantum chemical method was used in this study. The structures of the twelve organic compounds were optimized by the Density Functional Theory B3LYP/6-311G method, as well as their quantum properties. It was shown that six molecular descriptors were negatively correlated to imax while other three descriptors were positively correlated to imax. Among them, dipole moment had the greatest effect on the oxidation thermodynamics of the twelve organic compounds. Once a correlation between molecular descriptors and imax is established, SCWO can be run at an appropriate temperature according to molecular structure. | Yaqin Tan Zhemin Shen Weimin Guo Chuang Ouyang Jinping Jia Weili Jiang Haiyun Zhou | 2014 | Journal of Environmental Sciences2014，26，3： | 2 |
| 2 | Directional terahertz holography with thermally active Janus metasurface显示文摘Dynamic manipulation of electromagnetic(EM)waves with multiple degrees of freedom plays an essential role in enhancing information processing.Currently,an enormous challenge is to realize directional terahertz(THz)holography.Recently,it was demonstrated that Janus metasurfaces could produce distinct responses to EM waves from two opposite incident directions,making multiplexed dynamic manipulation of THz waves possible.Herein,we show that thermally activated THz Janus metasurfaces integrating with phase change materials on the meta-atoms can produce asymmetric transmission with the designed phase delays.Such reconfigurable Janus metasurfaces can achieve asymmetric focusing of THz wave and directional THz holography with free-space image projections,and particularly the information can be manipulated via temperature and incident THz wave direction.This work not only offers a common strategy for realizing the reconfigurability of Janus metasurfaces,but also shows possible applications in THz optical information encryption,data storage,and smart windows. | Benwen Chen Shengxin Yang Jian Chen Jingbo Wu Ke Chen Weili Li Yihui Tan Zhaosong Wang Hongsong Qiu Kebin Fan Caihong Zhang Huabing Wang Yijun Feng Yunbin He Biaobing Jin Xinglong Wu Jian Chen Peiheng Wu | 2023 | Light(Science & Applications)2023，12，6： | 1 |

| 6 | Data Mining Based Integrated Electric-Gas Energy System Multi-Objective Optimization显示文摘With the proposal of carbon neutrality,how to improve the proportion of clean energy in energy consumption and reduce carbon dioxide emissions has become the important challenge for the traditional energy industry.Based on the idea of multi-energy complementarity,a typical integrated energy system consisting of electric system and gas system is constructed based on the application of power to gas(P2G)technology and gas turbine in this paper.Furthermore,a multi-objective optimization model with economic improvement,carbon emission reduction and peak-load shifting as objectives is proposed,and solved by BSO algorithm.Finally,a typical power-gas coupling system is selected as an example to verify the effectiveness of the model.The results showed that the proposed multi-objective optimization model based on BSO algorithm can better play the complementary characteristics of the electric and gas system,and significantly improve the comprehensive benefits of system operation. | Zhukui Tan Yongjie Ren Hua Li Weili Ren Xichao Zhou Ming Zeng | 2022 | Energy Engineering2022，119，6： | 0 |
