3关于中澳自由贸易协议潜在优势的分析模型——一份为中澳自由贸易协议可行性研究作准备的独立报告显示文摘1.2002年,为了促进双边贸易和投资,中国和澳大利亚建立了一个经济贸易框架。在这个框架下,一项关于未来中澳自由贸易协定(FTA)的联合可行性研究已经出炉。2.受澳大利亚外交贸易部委任,莫纳什大学的政策研究中心对关于中澳自由贸易协定所带来的潜在利益进行模型分析,并与来自中国社科院和南开大学的专家共同着手这项研究。3.在这项研究中,我们从三个方面对自由贸易协定进行模拟:消除商品贸易中的边境保护主义、投资自由化以及消除服务贸易壁垒。分析框架为一个多国家、多部门的可计算的一般均衡模型,即'莫纳什的多国家模型'。在我们的模拟中,假设基于自由贸易协定下的政策调整是于2006年开始贯彻落实的。4.在模拟FTA下政策调整所带来的冲击方面,我们首先模拟了一个常规发展模式(或称'基准模式'),基准模式描述了在中澳没有签订FTA情况下中国和澳大利亚经济的发展进程。与基准假设相比,其改变程度将被视为FTA下政策调整所带来的效应。5.从模型中,我们可以得出这样的结论:FTA使得中澳两国的产出增加并使得福利提高。据估计,FTA将提高中澳两国2006年至2015年期间的实际国内生产总值(GDP)和实际国民生产总值(GNP)的现值(见42页图表7.1),数值如下:澳大利亚实际GDP:180亿美元中国实际GDP:640亿美元澳大利亚实际GNP:220亿美元中国实际GNP:520亿美元6.从2005年至2015年期间的年均增长率方面来讲,FTA估计将使澳大利亚的实际GDP年均增长0.039个百分点,使中国的实际GDP年均增长0.042个百分点。7.两国实际GDP的增长主要归功于不断增加的资本、不断提高的生产率水平和得到优化利用的资源。澳大利亚实际GDP增长的一个潜在的重要因素就是贸易条件的改善。8.通过不断增长的双边贸易和投资,FTA强化了中澳双方的经济合作伙伴关系;就整体而言,它也在世界范围内创造了贸易:由于中澳FTA的签订,世界进口量相较于基线水平也相应增长。9.为了更好地利用资源,两国实现了各部门之间的劳动力调整,这主要是为了消除商品贸易边境保护主义。然而,由于两国之间的互补性,部门间的这种劳动力再分配还是更倾向于促进两国间已发生的自然调整进程。而且,与中澳两国在还没有自由贸易协定时的全球化中已发生的合作相比,这种调整只能属于小规模范畴的调整。10.澳大利亚从自由贸易协定获利最大的产业有谷物、羊毛织品、绒线、矿物和有色金属。中国获利最大的产业则是制造业,特别是纺织品、服装和其它杂项制成品(如玩具和体育用品等);而两国的服务部门则都能从FTA中获益。11.如果2006年至2010年期间,政策调整能够逐步实施,则至2015年FTA所带来的长期效应将和在2006年完全贯彻执行FTA的效果没有区别。然而,越早实施FTA将会使两国更早获益,而相比较而言,如果采取不急不愠的措施,那么其导致实际GDP和实际GNP获益的现值将减少。Yinhua MAI Philip ADAMS Mingtai FAN Ronglin LI Zhaoyang ZHENG 黄姗姗 郑秀莲 王思婷 熊爱宗 洪冬梅 2007经济资料译丛2007,,3:3

10Strategies for high-performance perovskite solar cells from materials, film engineering to carrier dynamics and photon management显示文摘In recent years,halide perovskite solar cells(HPSCs)have attracted a great atten-tion due to their superior photoelectric performance and the low-cost of processing their quality films.In order to commercialize HPSCs,the researchers are focusing on developing high-performance HPSCs.Many strategies have been reported to increase the power conversion efficiency and the long-term stability of HPSCs over the past decade.Herein,we review the latest efforts and the chemical-physical principles for preparing high-efficiency and long-term stability HPSCs in particu-lar,concentrating on the perovskite materials,technologies for perovskite films,charge transport materials and ferroelectric effect to reduce the carrier loss,and photon management via plasmonic and upconversion effects.Finally,the key issues for future researches of HPSCs are also discussed with regard to the require-ments in practical application.Huilin Li Chong Chen Hangyu Hu Yu Li Zhitao Shen Fumin Li Ying Liu Rong Liu Junwei Chen Chao Dong Sally Mabrouk Raja Sekhar Bobba Abiral Baniya Mingtai Wang Quinn Qiao 2022InfoMat2022,4,7:0
11Molecular Dynamics Simulation of Interface Properties between Water-Based Inorganic Zinc Silicate Coating Modified by Organosilicone and Iron Substrate显示文摘The interface properties of Fe(101)/zinc silicate modified by organo-siloxane(KH-570)was studied by using the method of molecular dynamics simulation.By calculating the temperature and energy fluctuation of equilibrium state,equilibrium concentration distribution,MSD of layer and different groups,and interaction energy of two interface models,the influencing mechanism on the interface properties of adding organosiloxane into coating system was studied at the atomic scale.It shows that the temperature and energy of interface oscillated in a small range and it was exited in a state of dynamic equilibrium within the initial simulation stage(t<20 ps).It can be seen from the multiple peak states of concentration distribution that the iron substrate,organo-siloxane and zinc silicate are distributed in the form of a concentration gradient in the real environment.The rapid diffusion of free zinc powder in zinc silicate coating was the essential reason that affected the comprehensive properties of coating.The interface thickness decreased from 7.45 to 6.82Å,the MSD of free zinc powder was effectively reduced,and the interfacial energy was increased from 104.667 to 347.158 kcal/mol after being modified by organo-siloxane.Hengjiao Gao Yuqing Xiong Kaifeng Zhang Shengzhu Cao Mingtai Hu Yi Li Ping Zhang Xiaoli Liu 2023Journal of Renewable Materials2023,11,4:0
12Experimental and theoretical insights into copper phthalocyanine-based covalent organic frameworks for highly efficien radioactive iodine capture显示文摘Exploring efficient materials for capturing radioactive iodine in nuclear waste is of great significance for the progress of nuclear energy as well as the protection of ecological environment.Covalent organic frameworks(COFs)have emerged as promising adsorbents because of their predesignable and functionalizable skeleton structures.However,it remains a grand challenge to achieve large scale preparation of COFs.In this work,we developed a mild and efficient microwave irradiation method instead of the traditional solvothermal method to prepare copper phthalocyanine-based covalent organic frameworks(Cu_(x)Pc-COFs)within only 15 min.The nitrogen-rich 1,2,4,5-tetracarbonitrilebenzene(TCNB)was selected as the solely organic ligand to construct copper phthalocyanine-based 2D conjugated COFs.The resultant Cu_(x)Pc-COFs exhibited excellent iodine enrichment with 2.99 g/g for volatile iodine and 492.27 mg/g for iodine-cyclohexane solution,respectively,outperforming that of many porous materials.As indicated by spectroscopic analysis and DFT calculations,this impressive adsorption performance can be attributed to the charge transfer arising from nitrogen-rich phthalocyanine structures and electron-richπ-conjugated systems with iodine molecules.Moreover,the strong electrostatic interaction between Cu(Ⅱ)on chelate centers and polyiodide anions(I_(x)^(-))also play an important role in the firmly trapping radioactive iodine.Therefore,this study provides a facile and intelligent approach to implement metal-based COFs for the remediation of toxic radioactive iodine.Xuewei Liu Anrui Zhang Ran Ma Bo Wu Tao Wen Yuejie Ai Mingtai Sun Jie Jin Suhua Wang Xiangke Wang 2022Chinese Chemical Letters2022,33,7:0
13Synergistic engineering of hole transport materials in perovskite solar cells显示文摘In this work,methylammonium lead triiodide(CH3NH3PbI3)perovskite solar cells with efficiencies higher than 18%were achieved using a new nanocomposite hole transport layer(HTL)by doping poly(ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)with a mixed dopant of polyaniline(PANI)and graphene oxide(GO).A synergistic engineering between GO,PANI,and PEDOT:PSS was accomplished to introduce additional energy levels between perovskite and PEDOT:PSS and increase the conductivity of PEDOT:PSS.Kelvin probe force microscope results confirmed that adding GO to PEDOT:PSS/PANI composite significantly reduced the average surface potential.This increased the open circuit voltage(Voc)to 1.05 V for the GO/PEDOT:PSS/PANI nanocomposite perovskite solar cells from the pristine PEDOT:PSS(Voc=0.95 V)and PEDOT:PSS/PANI(Voc=0.99 V).In addition,adding PANI to the HTLs substantially enhanced short circuit current density(Jsc).This was supported by the current sensing-atomic force microscopy(CS-AFM)and conductivity measurements.The PANI doped films showed superior electrical conductivity compared with those without PANI as indicated by CS-AFM results.PANI can fill the gaps between the microflakes of GO and give rise to more compact hole transport material(HTM)layer.This led to a higher Jsc after doping with PANI,which was consistent with the incident photon-to-current efficiency and electrochemical impedance spectroscopy results.The results of X-ray diffraction(XRD)and AFM indicated the GO/PANI doped HTMs significantly improved the crystallinity,topography,and crystal size of the perovskite film grown on their surface.A higher efficiency of 18.12%for p-i-n perovskite solar cells has been obtained by adding the mixed dopant of GO,PANI,and PEDOT:PSS,demonstrating better stability than the pristine PEDOT:PSS cell.Sally Mabrouk Behzad Bahrami Hytham Elbohy Khan Mamun Reza Ashim Gurung Mao Liang Fan Wu Mingtai Wang Shangfeng Yang Qiquan Qiao 2020InfoMat2020,2,5:0
14Phenylformamidinium-enabled quasi-2D Ruddlesden-Popper perovskite solar cells with improved stability显示文摘Two-dimensional(2D)/quasi-2D perovskite solar cells(PSCs)incorporating organic spacer cations exhibit appealing ambient stability in comparison with their 3D analogs.Most reported organic spacer cations are based on ammonium,whereas formamidinium(FA^(+))has been seldom applied despite that FA has been extensively used in high-efficiency 3D PSCs.Herein,a novel FA-based organic spacer cation,4-chloro-phenylformamidinium(CPFA^(+)),is applied in quasi-2D Ruddlesden-Popper(RP)PSCs for the first time,and methylammonium chloride(MACl)is employed to promote crystal growth and orientation of perovskite film,resulting in high power conversion efficiency(PCE)with improved stability.Upon incorporating CPFA+organic spacer cation and MACl additive,high-quality quasi-2D CPFA_(2)MA_(n-1)Pb_(n)(I_(0.857)Cl_(0.143))_(3n+1)(n=9)perovskite film forms,exhibiting improved crystal orientation,reduced trap state density,prolonged carrier lifetime and optimized energy level alignment.Consequently,the CPFA_(2)MA_(n-1)Pb_(n)(I_(0.857)Cl_(0.143))_(3n+1)(n=9)quasi-2D RP PSC devices deliver a highest PCE of 14.78%.Moreover,the un-encapsulated CPFA-based quasi-2D RP PSC devices maintain~80%of its original PCE after exceeding 2000 h storage under ambient condition,whereas the 3D MAPb I3counterparts retain only~45%of its original PCE.Thus,the ambient stability of quasi-2D RP PSC devices is improved obviously relative to its 3D MAPb I3counterpart.Xingcheng Li Wanpei Hu Yanbo Shang Xin Yu Xue Wang Weiran Zhou Mingtai Wang Qun Luo Chang-Qi Ma Yalin Lu Shangfeng Yang 2022Journal of Energy Chemistry2022,31,3:0
