The PP-s-CA[PAM MIP exhibited an obvious improvement in terms of adsorption capacity for FN compared with non-imprinted polymer （NIP）. The PP-s-CA/PAM MIP was successfully used for the culture of mouse fibroblast cells （L929） and the results showed that PP-s-CA]PAM MIP exhibited better cell adherence performance than the NIP did.展开更多

One of the approaches in anti-icing is to reduce ice adhesion strength, seeking spontaneous de-icing processes by natural forces of gravity or by winds. In order to enable tai- lored surface icephobicity design, research requires a good theoretical understanding of the atomistic interacting mechanisms between water/ice molecules and their adhering substrates. Herein, this work focuses on using atomistic modeling and molecular dynamics simulation to build a nanosized ice-cube adhering onto silicon surface, with different contact modes of solid-solid and solid-liquid-solid patterns. This study provides atomistic models for probing nanoscale ice adhesion mechanics and theoretical platforms for explaining experimental results.展开更多
