Journal ArticleDOI
Study on hydrophilicity of polymer surfaces improved by plasma treatment
Jiangnan Lai,Bob Sunderland,Jianming Xue,Sha Yan,Weijiang Zhao,Melvyn Folkard,Barry D. Michael,Yugang Wang +7 more
TL;DR: In this article, the surface properties of polycarbonate (PC), polypropylene (PP), polyethylene terephthalate (PET) samples treated by microwave-induced argon plasma have been studied with contact angle measurement, X-ray photoelectron spectroscopy (XPS) and scanned electron microscopy (SEM).
Journal ArticleDOI
Effects of AL addition on microstructure and mechanical properties of AlxCoCrFeNi High-entropy alloy
Tengfei Yang,Songqin Xia,Shi Liu,Chenxu Wang,S. Q. Liu,Yong Zhang,Jianming Xue,Sha Yan,Yugang Wang +8 more
TL;DR: In this article, the effects of Al on microstructure and mechanical properties of AlxCoCrFeNi (x=0.1, 0.75 and 1.5) high-entropy alloys were systematically studied by using various characterization methods.
Journal ArticleDOI
Radiation tolerance of Cu/W multilayered nanocomposites
Yuan Gao,Yuan Gao,Tengfei Yang,Jianming Xue,Sha Yan,Shengqiang Zhou,Yugang Wang,Dixon T. K. Kwok,Paul K. Chu,Yanwen Zhang,Yanwen Zhang,Yanwen Zhang +11 more
TL;DR: In this article, magnetron sputtered Cu/W multilayer samples with individual layer thicknesses from 2.5 to 50nm were irradiated by 50-keV He+ ions at ion fluences from 7.2 to 6.6 m−2 at room temperature.
Journal ArticleDOI
Precipitation behavior of AlxCoCrFeNi high entropy alloys under ion irradiation.
Tengfei Yang,Songqin Xia,Shi Liu,Chenxu Wang,S. Q. Liu,Yuan Fang,Yong Zhang,Jianming Xue,Sha Yan,Yugang Wang +9 more
TL;DR: This study demonstrates the structural stability of single-phase HEAs under irradiation and provides important implications for searching for HEAs with higher irradiation tolerance, based on the irradiation-induced/enhanced precipitation theory.
Journal ArticleDOI
Effect of SiO2 substrate on the irradiation-assisted manipulation of supported graphene: a molecular dynamics study
TL;DR: The results indicate that the substrate is an important factor in the process of ion-irradiation-assisted engineering of the properties of graphene and the striking finding that it is possible to dope graphene with sputtered atoms from the substrate and the implantation probability is considerable at optimal energies.
