great strides have been made in understanding surfactant aggregation.
Those experimental studies, however, have produced little insight into
understanding the behavior of surfactants at the molecular level; the
mechanics of which are still to be explored. Consequently, new
developments in molecular dynamics (MD) simulation have been directed
toward this area of study.
examines dilute and concentrated surfactant systems at the solid-liquid
interface. MD simulations are run to study dodecyltrimethyl ammonium

silica and graphite surfaces, and during indentation. Surfactants have
been used for dispersion in detergents, paints, pharmaceutics, and
microelectronics such as in chemical mechanical polish (CMP) processing
of silicon wafers.
