Fang, C. (author), Mohammadi, V. (author), Nihtianova, S. (author), Sluiter, M.H.F. (author)Abstract Deposition of a thin B layer via decomposition of B2H6 on Si (PureB process) produces B-Si junctions which exhibit unique electronic and optical properties. Here we present the results of our systematic first-principles study of BHn (n=0-3) radicals on Si(100)2x1:H surfaces, the initial stage of the PureB process. The calculations...journal article 2017

Zhang, X.Y. (author), Fang, G (author), Zhou, J. (author)Additive manufacturing (AM), nowadays commonly known as 3D printing, is a revolutionary materials processing technology, particularly suitable for the production of low-volume parts with high shape complexities and often with multiple functions. As such, it holds great promise for the fabrication of patient-specific implants. In recent years,...journal article 2017

Fang, G (author), Nguyen, D.T. (author), Zhou, J. (author)Extrusion through the porthole die is a predominant forming process used in the production of hollow aluminum alloy profiles across the aluminum extrusion industry. Longitudinal weld seams formed during the process may negatively influence the quality of extruded profiles. It is therefore of great importance to understand the formation of...journal article 2017

Fang, Jiayu (author), Chen, Y. (author), Yao, P. (author), Su, M. (author)The effective roughness height is an important parameter in coastal sediment transport models. It has been extensively investigated in the past but few research results are related to the high-concentrated flows which often occur in a silty coast. A series of experiments has been carried out in a wave-current flume with silt-sized sediment...journal article 2016
