| 1 | Mercury Emission From Coal-fired Power Plants in China显示文摘燃煤是最大的人为汞排放源之一,燃煤电厂的汞排放控制问题也越来越为人们所关注。该文将目前公布的中国电厂的汞排放数据进行筛选汇总,得到18个电厂的汞排放数据,通过对比和分析,总结出了符合我国燃煤电厂特点的一般性汞排放规律。结果表明:与美国煤种相比,我国的燃煤具有低氯、高灰的特性,这不利于汞的排放控制;循环流化床燃烧可能会因燃尽率的不同而较煤粉炉燃烧易获得较高的Hgp;空气污染控制设备的使用能够有效地减少汞排放,选择性催化还原+静电除尘器/布袋除尘器+石灰石-石膏湿法脱硫(SCR+ESP/FF+WFGD)组合的平均脱汞率可达71.48%;SCR的大规模应用可能会将汞大量转移到飞灰和脱硫石膏中,带来二次污染的问题。 | YIN Libao ZHUO Yuqun XU Qisheng ZHU Zhenwu DU Wen AN Zhongyi | 2013 | 中国电机工程学报2013，33，29： | 29 |
| 2 | Dielectrophoretic assembly of carbon nanotubes and stability analysis显示文摘Nanoscale dimensions and remarkable properties of carbon nanotubes make them promising building blocks for nanoelectronics.One requirement is the need to manipulate single or multiple carbon nanotubes to bridge electronic conductors.In this paper,multi-walled carbon nanotubes with a variety of sizes are assembled onto electrodes using alternative current electric felds by dielectrophoresis.The effect of the dielectrophoretic parameters and the nanotube size as well as the length uniformity on the assembly is experimentally investigated.Current–voltage characteristics of assembled carbon nanotubes are measured.The experimental results showed that both the dielectrophoretic parameters and length uniformity of carbon nanotubes have an infuence on the stability of assembly results.Choosing uniform carbon nanotubes with an appropriate length and suffcient stiffness,which are more controllable by dielectrophoresis,is necessary for an assembly of a small number of carbon nanotubes. | Libao An Craig Friedrich | 2013 | Progress in Natural Science:Materials International2013，23，4： | 9 |
| 3 | All-in-One Deposition to Synergistically Manipulate Perovskite Growth for High-Performance Solar Cell显示文摘Nonradiative recombination losses originating from crystallographic distortions and issues occurring upon interface formation are detrimental for the photovoltaic performance of perovskite solar cells.Herein,we incorporated a series of carbamide molecules(urea,biuret,or triuret)consisting of both Lewis base(-NH2)and Lewis acid(-C=O)groups into the perovskite precursor to simultaneously eliminate the bulk and interface defects.Depending on the different coordination ability with perovskite component,the incorporated molecules can either modify crystallization dynamics allowing for large crystal growth at low temperature(60℃),associate with antisite or undercoordinated ions for defect passivation,or accumulate at the surface as an energy cascade layer to enhance charge transfer,respectively.Synergistic benefits of the above functions can be obtained by rationally optimizing additive combinations in an all-in-one deposition method.As a result,a champion efficiency of 21.6%with prolonged operational stability was achieved in an inverted MAPbI3 perovskite solar cell by combining biuret and triuret additives.The simplified all-in-one fabrication procedure,adaptable to different types of perovskites in terms of pure MAPbI3,mixed perovskite,and all-inorganic perovskite,provides a cost-efficient and reproducible way to obtain high-performance inverted perovskite solar cells. | Yifan Lv Hui Zhang Jinpei Wang Libao Chen Lifang Bian Zhongfu An Zongyao Qian Guoqi Ren Jie Wu Frank Nuesch Wei Huang | 2020 | Research2020，，1： | 2 |
| 4 | Density functional theory study of B- and Si-doped carbons and their adsorption interactions with sulfur compounds显示文摘Understanding the adsorption interactions between carbon materials and sulfur compounds has far-reaching impacts,in addition to their well-known important role in energy storage and conversion,such as lithium-ion batteries.In this paper,properties of intrinsic B or Si single-atom doped,and B-Si codoped graphene(GR)and graphdiyne(GDY)were investigated by using density functional theory-based calculations,in which the optimal doping configurations were explored for potential applications in adsorbing sulfur compounds.Results showed that both B or Si single-atom doping and B-Si codoping could substantially enhance the electron transport properties of GR and GDY,improving their surface activity.Notably,B and Si atoms displayed synergistic effects for the codoped configurations,where B-Si codoped GR/GDY exhibited much better performance in the adsorption of sulfurcontaining chemicals than single-atom doped systems.In addition,results demonstrated that,after B-Si codoping,the adsorption energy and charge transfer amounts of GDY with sulfur compounds were much larger than those of GR,indicating that B-Si codoped GDY might be a favorable material for more effectively interacting with sulfur reagents. | Peng Guo Hong Zhang Shuliang Dong Libao An | 2024 | Carbon Energy2024，6，2： | 0 |
