Summary of "Droplet Morphology and Mobility on Lubricant-Impregnated Surfaces: A Molecular Dynamics Study."

The slippery liquid-infused porous surfaces (SLIPS) are gaining remarkable attention and have advanced performance in many fields. Although all SLIPS are related to lubricant-impregnated within nano-/micro- structures on a surface, they differ in many aspects, such as the morphology of droplets, the state of cloaking, the wetting edge, the lubricant thickness, etc. Requirements of the droplet morphology on SLIPS might change according to a specific application. Molecular dynamics based numerical model that can correctly simulate the SLIPS is developed and it is validated by comparing against the theoretical predictions for all possible stable states for a given droplet, lubricant, and solid surface. Based on this model, detailed analysis of the equilibrium states is conducted. In particular, we discover that the four possible stable states on SLIPS predicted by theoretical studies can be extended to eight states by considering the effects of lubricant thickness and surface geometry in addition to the interfacial tension and surface wettability. These findings could be used to determine conditions under which thermodynamically stable state exists on SLIPS. The dynamic behavior of a nanodroplet on the SLIPS is also studied which provides insights into how a proper increase of the lubricant thickness might increase the sliding velocity. The above findings and developed model are expected to provide significant guidelines for designing SLIPS.

Medical and Biotech [MESH] Definitions

A computer simulation developed to study the motion of molecules over a period of time.

An electrophoretic technique for assaying the binding of one compound to another. Typically one compound is labeled to follow its mobility during electrophoresis. If the labeled compound is bound by the other compound, then the mobility of the labeled compound through the electrophoretic medium will be retarded.

A family of low-molecular weight, non-histone proteins found in chromatin.

The upward or downward mobility in an occupation or the change from one occupation to another.

A spectroscopic technique which uses the Mossbauer effect (inelastic scattering of gamma radiation resulting from interaction with heavy nuclei) to monitor the small variations in the interaction between an atomic nucleus and its environment. Such variations may be induced by changes in temperature, pressure, chemical state, molecular conformation, molecular interaction, or physical site. It is particularly useful for studies of structure-activity relationship in metalloproteins, mobility of heavy metals, and the state of whole tissue and cell membranes.
