Journal ArticleDOI
The performance of silicon solar cells operated in liquids
TL;DR: In this article, the performance of solar cells immersed in liquids was examined under simulated sunlight, and it was found that the optic properties of the liquids can cause minor efficiency changes on the solar cells, while the electric properties of liquids, the molecular polarizable and ions, are responsible for the most of the changes.
Journal ArticleDOI
Energy, exergy, economic, and environmental analysis of an integrated system of high-temperature heat pump and gas separation unit
Xiaoqiong Li,Yufeng Zhang,Lei Fang,Jin Zhendong,Zhang Yan,Yu Xiaohui,Xuelian Ma,Na Deng,Zhangxiang Wu +8 more
TL;DR: In this paper, a novel integrated system consisting of a high-temperature heat pump providing 120-130°C heat and a gas separation unit was developed to recover the industrial waste heat and replace the low-pressure steam used in traditional refinery process.
Journal ArticleDOI
Synergistic effect and mechanism of mass transfer and catalytic oxidation of octane degradation in yolk-shell Fe3O4@C/Fenton system
Yuan Zhuang,Siyi Yuan,Jiemin Liu,Zhang Yan,Hao Du,Chuandong Wu,Peng Zhao,Haiying Chen,Yipu Pei +8 more
TL;DR: In this paper, a yolk-shell Fe3O4@C/Fenton system was designed to improve octane removal efficiency, which showed a synergistic effect of mass transfer enhancement and catalytic oxidation.
Journal ArticleDOI
Degradation of octane using an efficient and stable core-shell Fe3O4@C during Fenton processes: Enhanced mass transfer, adsorption and catalysis
Yuan Zhuang,Jiemin Liu,Siyi Yuan,Ben Ge,Hao Du,Chen Qu,Haiying Chen,Chuandong Wu,Wenhui Li,Zhang Yan +9 more
TL;DR: In this paper, a core-shell Fe3O4@C was employed as an advanced oxidation microreactor for hydrophobic and refractory VOC removal during the Fenton process, and octane was chosen as a typical target pollutant.
Journal ArticleDOI
Analysis of a high temperature heat pump using BY-5 as refrigerant
TL;DR: In this article, the authors proposed a new binary near-azeotropic mixture named BY-5 as the refrigerant of the high-temperature heat pump, which can product heat at the temperature of 135°C with good performance.
