Lin, Yan (author), Qian, Chengduo (author), Shi, Jingtao (author), Zhang, Yuzhen (author), Ren, S. (author), Nan, Guozhi (author), Kong, Xiangjun (author), Fan, Weiyu (author)Compared with traditional asphalt, emulsified asphalt occurs to be a better low-temperature usability and environmental adaptability, which can reduce environmental pollution and energy consuming during road construction. The low-temperature ductility is a very important indicator to evaluate the environmental adaptability of emulsified asphalt....journal article 2022

Qian, Kun (author), Tang, Linkai (author), Wagemaker, M. (author), He, Yan Bing (author), Liu, Dongqing (author), Li, Hai (author), Shi, Ruiying (author), Li, Baohua (author), Kang, Feiyu (author)Through a facile sodium sulfide (Na<sub>2</sub>S)-assisted hydrothermal treatment, clean and nondefective surfaces are constructed on micrometer-sized Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> particles. The remarkable improvement of surface quality shows a higher first cycle Coulombic efficiency (≈95%), a significantly enhanced cycling...journal article 2017

Shi, Q. (author), Zudov, M. A. (author), Qian, Q. (author), Watson, J.D. (author), Manfra, M. J. (author)We investigate quantum Hall stripes under an in-plane magnetic field B in a variable-density two-dimensional electron gas. At filling factor ν=9/2, we observe one, two, and zero Binduced reorientations at low, intermediate, and high densities, respectively. The appearance of these distinct regimes is due to a strong density dependence of the...journal article 2017

Fu, X. (author), Ebner, Q. A. (author), Shi, Q. (author), Zudov, M. A. (author), Qian, Q. (author), Watson, J.D. (author), Manfra, M. J. (author)We performed effective mass measurements employing microwave-induced resistance oscillation in a tunable-density GaAs/AlGaAs quantum well. Our main result is a clear observation of an effective mass increase with decreasing density, in general agreement with earlier studies which investigated the density dependence of the effective mass...journal article 2017
