They can be very tenaciously attached and at the same time very labile, with relaxation times ranging from 10<sup>-9</sup> – 10<sup>5</sup> sec, some 14 orders of magnitude, affording them remarkable properties. In recent years a new paradigm has emerged: This reveals the remarkable – and unsuspected - role of hydration layers in modulating frictional forces between sliding surfaces or molecular layers in aqueous media, termed hydration lubrication, in which the lubricating mode is completely different from the classic one of oils or surfactants. The talk will focus on very recent studies of these effects, ranging from the behaviour of water and hydrated polymers in nanometrically-confined films to the molecular origins of biological lubrication. </font></font></p> <p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px" align="justify"><font face="Arial, Helvetica, sans-serif"><font size="2"></font></font> </p> <p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px" align="justify"><font face="Arial, Helvetica, sans-serif"><font size="2"><font color="#697da9"><span style="FONT-WEIGHT: 700"><font color="#697da9"><a href="http://sciences.hit.ac.il/events/ps/fliers.2009-2010/klein.09.mar.2010.pdf" target="_blank">Get the flier...</a></font></span></font></font></font></p><SPAN STYLE="display: none"> <P>Acetylenide minutes, pointedly?
