Alternative dissipation mechanisms and the effect of the solvent in friction between polymer brushes on rough surfaces

S De Beer, MH Müser - Soft Matter, 2013 - pubs.rsc.org
Surfaces covered with end-anchored polymers under good solvent conditions have
excellent tribological properties. The friction between such surfaces is commonly attributed …

Modeling the protective role of bacterial lipopolysaccharides against membrane-rupturing peptides

S Nourbakhsh, L Yu, BY Ha - The Journal of Physical Chemistry B, 2021 - ACS Publications
Lipopolysaccharide (LPS) is a key surface component of Gram-negative bacteria, populating
the outer layer of their outer membrane. A number of experimental studies highlight its …
