Numerical simulation study on air quality in aircraft cabins

Journal of Environmental Sciences 2017年第6期29卷 52-61页

Ltd.Tianjin 300308China College of Chemical Engineering Wuhan Textile UniversityWuhan 430073China College of Civil Aviation Nanjing University of Aeronautics and AstronauticsNanjing 210016China

Air pollution is one of the main factors that affect the air quality in aircraft cabins, and the use of different air supply modes could influence the distribution of air pollutants in cabins. Based on the traditional ceiling air supply mode used on the B737NG, this study investigated another 3 different kinds of air supply modes for comparison： luggage rack air supply mode, joint mode combining ceiling and luggage rack air supply, and joint mode combining ceiling and individual air supply. Under the above 4 air supply modes, the air velocity, temperature and distribution of air pollutants in a cabin full of passengers were studied using computational fluid dynamics （CFD）, and carbon dioxide （CO2） and formaldehyde were selected as 2 kinds of representative air pollutants. The simulation results show that the joint mode combining ceiling and individual air supply can create a more uniform distribution of air velocity and temperature, has a better effect on the removal of CO2 and formaldehyde, and can provide better air quality in cabins than the other 3 modes.

Anion-π interactions as a new member of supramolecular weak interactions are still in the young stage,but they already attract considerable attentions. Now the concerns are shifting from recognition to construction of functional systems. In this review, the anion-π functional systems especially anion-πcatalysis and self-assembly were highlighted and summarized together with several solid and recent examples of host-guest recognition. These applications suggest that the great potential of these new interactions.

PTB7-Th based organic solar cell with a high V_(oc) of 1.05 V by modulating the LUMO energy level of benzotriazole-containing non-fullerene acceptor

引用

Science Bulletin 2017年第18期62卷 1275-1282页

作者： Bo Xiao yingjie zhao Ailing Tang Haiqiao Wang Jing Yang Erjun Zhou CAS Key Laboratory of Nanosystem and Hierarchical Fabrication CAS Center for Excellence in Nanoscience National Center for Nanoscience and Technology Beijing 100190 China University of Chinese Academy of Sciences Beijing 100049 China State Key Laboratory of Organic-Inorganic Composite Beijing University of Chemical Technology Beijing 100029 China

The open-circuit voltage （Voc） of classical photovoltaic polymers, such as P3HT and PTB7-Th, are always restricted when combining with fullerene derivatives, due to the difficulty of modulating the energy levels of fullerene derivatives. Thus, design of new non-fullerene small molecule acceptor （NFSMA） is very significant to match with these mature polymer donors and improve the Voc and power conversion efficiency （PCE）. Here, a new benzotriazole （BTA）-based NFSMA, BTA7 was synthesized by adopting A2----A1--D--A1--A2 type molecular backbone. By using a strong electron-accepting unit of malononitrile （M） as terminal segment A2, BTA7 demonstrates strong crystallinity, red-shifted absorption spectrum and down-shifted lowest unoccupied molecular orbital （LUMO） energy levels in comparison with BTA1 and BTA2. Organic solar cells （OSCs） based on PTB7-Th：BTA7 realized a high Voc of 1.05 V with a moderate PCE of 4.60%. The energy loss （Eloss = Eg - eVoc） of 0.53 eV is lower than the experiential minimum value of 0.6 eV, which indicates PTB7-Th still has large potential to improve the Voc and photovoltaic performance after the development of novel electron acceptors.
