Autor: Haibin Zhang, Yuanjin He, Zhenyu Lai, Tao Yan, Zhongyuan Lu, Feng Li, Xin He, Xiaoling Fan, Shuzhen Lv

Publikováno v: Construction and Building Materials. 209:32-40

Cadmium pollution is a type of heavy-metal pollution that is harmful to human health and the environment. Magnesium phosphate cement (MPC) is a fast-setting material with rapid strength development that can solidify and stabilize pollutants quickly.

High coercivity and small grains of FePt films annealed in high magnetic fields

Autor: W B Sun, Yuanjin He, W H Mao, M Motokawa, Seiji Mitani, H. Y. Wang

Publikováno v: Journal of Physics D: Applied Physics. 39:1749-1753

The coercivity and grain size of equiatomic FePt alloy films annealed at 500 and 600 °C with different magnetic fields of 0–70 kOe have been investigated. It is found that applying a magnetic field with appropriate strength during postdeposition a

THE GROWTH OF MnSi1.73 PREPARED BY SPARK PLASMA SINTERING

Autor: Yuanjin He, Yi Dong Wu, Zhi Min Wang

Publikováno v: International Journal of Modern Physics B. 18:87-93

Crystals of MnSi 1.73 were prepared by Spark Plasma Sintering (SPS) technique, analyzed by X-ray diffraction (XRD), and invested by metalogragh and scanning electron microscopy (SEM). The growth processes of the samples were studied. It was found tha

Enhancing yield stress of electrorheological fluids with liquid crystal additive

Autor: Yuanjin He, Hong Chen, Weili Luo, Xiaodong Duan

Publikováno v: Journal of Physics D: Applied Physics. 33:696-699

The enhancement of yield stress of NaY/insulating oil electrorheological (ER) fluid is found by adding a liquid crystal additive with a higher dielectric constant than that of the carrier fluid. The yield stress increases with additive's concentratio

The Effect of Particle Shape on Water-Free Mica ER Fluids

Autor: Xiaodong Duan, Yuanjin He, Hong Chen, Weili Luo

Publikováno v: Journal of Intelligent Materials Systems and Structures. 11:43-46

The yield stresses of the water-free mica ER fluid for different particle sizes and concentrations are investigated. For a certain particle size, there is an optimum concentration for maximum yield stress. We found that the larger the particle size,

Enhancement in ordering of FePt films by magnetic field annealing

Autor: M. Motokawa, S. Mitani, Yuanjin He, X. K. Ma, H. Y. Wang

Publikováno v: Applied Physics Letters. 85:2304-2306

Effect of magnetic field annealing on chemical ordering of FePt films has been investigated. It is found that the ordering rate in FePt films is enhanced by applying a magnetic field during postdeposition annealing. Measurements of the structure and

PHASE TRANSITION IN BA-Y-CU-O COMPOUND AS PROBED BY POSITRON ANNIHILATION

Autor: Weizhong Yu, Yuanjin He, Huang Min, jiajiong Xiong, Liying Cai

Publikováno v: International Journal of Modern Physics B. :475-478

For the first time positron annihilation spectroscopy was used to probe the phase transition in Ba-Y-Cu-O system between temperature 80–440K. It was found that beside the superconducting transition at 90K, another phase transition at 225K could be
