1Surfactant-Enhanced Soil Washing for Removal of Petroleum Hydrocarbons from Contaminated Soils: A Review显示文摘An increase in energy demand leads to further exploration, transportation, and utilization of petroleum, which creates severe soil contamination because of recurrent accidents and oil spills. Remediation of these contaminated soils is challenging. Among many treatment methods practiced for remediation of petroleum-contaminated soils, surfactant-enhanced soil washing has been widely practiced as a preferred treatment option, as it is a fast and environmentally accepted method. In this paper, we review research undertaken on various anionic, nonionic, cationic, biological, and mixed surfactants for the remediation of petroleum hydrocarbon-contaminated soils. Upcoming surfactants like gemini and switchable surfactants are summarized. We assess the challenges and opportunities of in-situ and ex-situ soil washing, the mechanisms of surfactant-enhanced soil washing, and the criteria to follow for surfactant selection.Furthermore, we briefly discuss the operational and environmental factors affecting soil washing efficiency and soil and surfactant properties affecting surfactant adsorption. We also describe the advantages of coupling soil washing with effluent treatment and surfactant reuse challenges and opportunities. Moreover, challenges and possible new directions for future research on surfactant-enhanced soil washing are proposed.Abayneh Ayele BEFKADU CHEN Quanyuan 2018Pedosphere2018,28,3:20

3Accelerated carbonation and leaching behavior of the slag from iron and steel making industry显示文摘Ground granulated blast furnace slag (GGBFS) and steelmaking slag have been used as a raw material for cement production or as an aggregate to make concrete, which contribute aluminum, calcium, iron, and silicon oxides. The suitability of the slag for a particular application depends on its reactivity, cost, availability, and its influence on the properties of the resulting concrete. For the interest of durability studying of concrete in the presence of slag, the accelerated carbonation products and leaching behavior of the slag and Portland cement (PC) were studied. The experimental results confirmed that the slag was more resistant to carbonation compared to PC. The carbonation degree of GGBFS reduced by 17.74/; and the carbonation degrees of steelmaking slags reduced by 9.51/-11.94/. Carbonation neutralized the alkaline nature of the hydrated pastes and gave rise to the redox potential of the leachate slightly (30-77 mV). The carbonation also increased the release of most of the elements presented, except for calcium, to the aqueous environment. It is concluded that blend cements (PC plus slag) have economical advantages and better durability compared to PC.Quanyuan Chen Johnson Lingyun Zhu Menghong Yuan Hills 2007Journal of University of Science and Technology Beijing2007,14,4:5

7Solvability identification and feasibility restoring of divergent optimal power flow problems显示文摘Optimal power flow (OPF) has been considered as an important problem in power systems. Although several excellent algorithms, such as Newton method and interior point method, have been developed to solve the OPF problem, divergences still often occur. Till now, few works have focused on the solv- ability identification and feasibility restoring of divergent OPF problems. In this paper, we propose a systematic approach to identify the solvability of divergent OPF problems, and restore a feasible solu- tion for unsolvable OPF cases. The proposed approach consists of two phases: solvability identifica- tion phase (SIP) and feasibility restoring phase (FRP). In SIP, a novel methodology based on problem transformation and active set is adopted to identify the solvability of divergent OPF problem. If a fea- sible solution can be obtained in SIP, then this divergent OPF problem is solvable, otherwise, FRP is used to restore a feasible or optimal solution by relaxing soft constraints and load shedding. In FRP, a feasibility restoring model is presented, and a priority-listing strategy of restoring actions is proposed to restore the unsolvable OPF problems. Numerical studies indicate that the proposed SIP and FRP are reliable to diagnose the solvability of the divergent OPF problems, give an index to measure the un- solvability, and restore an unsolvable OPF case.QuanYuan Jiang ZhenXiang Han 2009Science China(Technological Sciences)2009,52,4:3
8STUDENTS' ATTITUDES TO EXPLICIT GRAMMAR TEACHING AND ITS RELATIONAHIP TO COMMUNICATION显示文摘Grammar teaching is greatly emphasised in English language teaching in China, but does it really attain the goal the students desire? An investigation was made with overseas students about their attitudes to explicit grammar teaching. The investigation reveals that grammar teaching should focus on developing the learners’ communicative ability more than presenting and explaining grammatical rules.Jin Quanyuan Nanjing University of Aeronautics and Astronautics 2000Chinese Journal of Applied Linguistics2000,23,1:3
9An Overview of Mineral Processing in China显示文摘The latest progress in mineral processing in China is described. It is also pointed out that the existing techno- logy can not meet the needs of economic development. The combined challenges of poor resources, economical benefits and environmental pollution issues require further research to upgrade the separation efficiency economically. The methods of mineral processing should play a more important pod in waste treatment such as wastewater treatment, the re- mediation of contaminated soil and the recycling of wastes. Biomineral technology will be utilised in the near future.Quanyuan Chen, Jingshen Zhang, Dianzuo Whng (Changsha Research Institute of Mining and Metallurgy, Changsha 410012, China General Research Institute for Nonferrous Metals, Beijing 100088, China) 2001Rare Metals2001,20,2:2
10ENERGY-EFFICIENT MICROWAVE COMPONENTS FOR MOBILE COMMUNICATION显示文摘In the coexisted world of 3G,4G,5G and many other specialized wireless communication systems,billions of connections could be existing for various information transmission types.Unluckily,data show that the increase of network capacity is heavily more than the increase of the network energy efficiency in recent years,which could lead to more energy consumption per transmitted bit in the future network.As basic units in mobile communication systems,microwave/RF components and modules play key rolesYuanan Liu Quanyuan Feng Fadhel M.

11OpenMP-based parallel transient stability simulation for large-scale power systems显示文摘This paper provides an OpenMP-based parallel Very Dishonest Newton(VDHN) algorithm with variable step size,running transient stability simulations(TSA) on multi-core computers.Under the framework of simultaneous solution method of TSA,the step-size control strategy is used according to the local truncation error theory firstly.Then,computation of the generation units,which is the most time-consuming part of the simulation,is dynamically dispatched to several cores using an α dynamic scheduling scheme to obtain workload balancing based on OpenMP.Due to the convergence of Newton-type iterations,an adaptive Jacobian update control strategy is applied to reduce the sequential part of the simulation and the overhead generated by OpenMP.Several large scale test cases verify the validity and practicability of the proposed parallel algorithm,showing that the proposed approach achieves high speed-up and a considerable reduction in parallel overheads.JIANG QuanYuan JIANG Han 2012Science China(Technological Sciences)2012,55,10:2
12Blue AIEgens bearing triphenylethylene peripheral:adjustable intramolecular conjugation and good device performance显示文摘The new approaches to construct deep blue aggregation-induced emission(AIE) materials have been explored, which control the conjugation by two different strategies, to make a great step for the commercialization of organic light-emitting diodes. In order to shorten the intramolecular conjugation length, triphenylethylene(t PE)was utilized to construct blue AIEgens as peripheral groups,instead of tetraphenylethylene(TPE), the famous AIE star molecule, to yield three blue AIEgens of 3,4-Bt PE-PI, 4,4-Bt PE-PI and 4,4-Bt PE-PPI. Nondoped electroluminescence devices are fabricated by using these three AIEgens as the emitting material layer, the best performance of 3.8 cd/A as the maximum current efficiency achieved at the commission internationale de l'Eclairage coordinates of(0.17, 0.18).Can Wang Le Li Xuejun Zhan Zhijun Ruan Yujun Xie Quanyuan Hu Shanghui Ye Qianqian Li Zhen Li 2016Science Bulletin2016,61,22:2
