Adsorption mechanism of mussel-derived adhesive proteins onto various self-assembled monolayers
Shizhe Huang,Qingfeng Hou,Donghong Guo,Hui Yang,Ting Chen,Fanghui Liu,Guangxin Hu,Minghui Zhang,Jian Zhang,Jinben Wang +9 more
TL;DR: In this paper, the adsorption behavior of mussel foot protein-1 (Mfp-1) onto self-assembled monolayers (SAMs) with varying wettability and chemistry, through quartz crystal microbalance with dissipation measurements, ellipsometry, X-ray photoelectron spectroscopy, and atomic force microscopy.
“Peeling Off” Mechanism of Asphaltenes from Solid/Liquid Interface in the Presence of a Highly Charged Amphiphilic Macromolecule
Ting Chen,Fanghui Liu,Shizhe Huang,Wei Zhang,Hui Wang,Qingfeng Hou,Donghong Guo,Aiqing Ma,Keji Sun,Hui Yang,Jinben Wang +10 more
TL;DR: In this paper, asphaltene desorption from silica-coated quartz crystal surface, in the presence of a highly charged amphiphilic macromolecule (polyacryloyloxyethyl-N,N-dimethyl-n-benzylammonium bromide, denoted as PASBn), was investigated through a quartz crystal microbalance with dissipation, atomic force microcopy, and ultraviolet spectroscopy measurements.

PAMAM-Based Dendrimers with Different Alkyl Chains Self-Assemble on Silica Surfaces: Controllable Layer Structure and Molecular Aggregation.
Minghui Zhang,Hui Yang,Wang Shujuan,Wei Zhang,Qingfeng Hou,Donghong Guo,Fanghui Liu,Ting Chen,Xu Wu,Jinben Wang +9 more
TL;DR: The results provided more detailed understanding of the effect of molecular structure on the self-assembled structures of amphiphilic dendrimers on solid surfaces, shedding light on the controlled microstructure and wettability of functional surface by modulating the length of hydrophobic chains of d endrimers and a potential application ofdendrimer-substrate combinations.
