CONCLUSIONS<br />

Molecular dynamics studies elucidate the nature <strong>of</strong> the boundary<br />

conditions and the slip length at solid-fluid <strong>in</strong>terfaces.<br />

Maxwell’s scenarios <strong>of</strong> behavior near the wall realized only <strong>in</strong><br />

the limit<strong>in</strong>g cases – crossover complicated<br />

The slip length (also <strong>in</strong> thermal slip) is a sensitive function <strong>of</strong><br />

the wall-fluid <strong>in</strong>teractions and <strong>of</strong> the density<br />

Reconstruction <strong>in</strong> the density pr<strong>of</strong>ile near the wall leads to<br />

a maximum <strong>in</strong> the flow velocity as a function <strong>of</strong> density<br />

Mixed wetability <strong>channels</strong> generate stationary plug flows <strong>in</strong> the<br />

non-wett<strong>in</strong>g regions. Different crossovers from wett<strong>in</strong>g to<br />

non-wett<strong>in</strong>g regions for the dense and Knudsen cases.<br />

Hydrophobic patterned surfaces give rise to the lotus-like behavior
