| 1 | Fundamental mechanisms and phenomena of clathrate hydrate nucleation显示文摘Insights into the mechanism of hydrate nucleation are of great significance for the development of hydrate-based technologies,hydrate relevant flow assurance,and the exploration of in situ natural gas hydrates.Compared with the thermodynamics of hydrate formation,understanding the nucleation mechanism is challenging and has drawn substantial attention in recent decades.In this paper,we attempt to give a comprehensive review of the recent progress of studies of clathrate hydrate nucleation.First,the existing hypotheses on the hydrate nucleation mechanism are introduced and discussed.Then,we summarize recent experimental studies on induction time,a key parameter evaluating the velocity of the nucleation process.Subsequently,the memory effect is particularly discussed,followed by the suggestion of several promising research perspectives. | Jinlong Cui Zhenfeng Sun Xiaohui Wang Bin Yu Shudong Leng Guangjin Chen Changyu Sun | 2019 | Chinese Journal of Chemical Engineering2019，27，9： | 11 |
| 2 | NiO nanoparticle-decorated SnO_(2)nanosheets for ethanol sensing with enhanced moisture resistance显示文摘In a high relative humidity(RH)environment,it is challenging for ethanol sensors to maintain a high response and excellent selectivity.Herein,tetragonal rutile SnO_(2)nanosheets decorated with NiO nanoparticles were synthesized by a two-step hydrothermal process.The NiO-decorated SnO_(2)nanosheet-based sensors displayed a significantly improved sensitivity and excellent selectivity to ethanol gas.For example,the 3 mol%NiO-decorated SnO_(2)(SnO_(2)-3Ni)sensor reached its highest response(153 at 100 ppm)at an operating temperature of 260℃.Moreover,the SnO_(2)-3Ni sensor had substantially improved moisture resistance.The excellent properties of the sensors can be attributed to the uniform dispersion of the NiO nanoparticles on the surface of the SnO_(2)nanosheets and the formation of NiO-SnO_(2)p–n heterojunctions.Considering the long-term stability and reproducibility of these sensors,our study suggests that the NiO nanoparticle-decorated SnO_(2)nanosheets are a promising material for highly efficient detection of ethanol. | Gaoqiang Niu Changhui Zhao Huimin Gong Zhitao Yang Xiaohui Leng Fei Wang | 2019 | Microsystems & Nanoengineering2019，5，1： | 3 |
