due to transverse velocity variations in a phenomenon now commonly referred to as Taylor dispersion.&#13;
It is well understood that the characteristics of the dispersion are sensitive to the channel’s cross-sectional&#13;
geometry. Here we demonstrate a method for manipulation of dispersion in a single microchannel via controlled&#13;
deformation of one side of the channel’s walls. Using a rapid-prototyped multi-layer microchip, the&#13;
lower channel wall is deformed by an external pressure source allowing us to characterize the dependence&#13;
of the dispersion on the deflection of the channel wall and overall channel aspect ratio. Our experimental&#13;
measurements are compared directly with theoretical predictions.</mods:abstract><mods:subject><mods:topic>Fluid Dynamics</mods:topic></mods:subject><mods:subject authority="fast" authorityURI="http://id.worldcat.org/fast" valueURI="http://id.worldcat.org/fast/01736696"><mods:topic>Microfluidics</mods:topic></mods:subject><mods:subject><mods:topic>Taylor Dispersion</mods:topic></mods:subject><mods:subject><mods:topic>Rapid-prototyped microchip</mods:topic></mods:subject><mods:language><mods:languageTerm authority="iso639-2b">English</mods:languageTerm></mods:language><mods:recordInfo><mods:recordContentSource authority="marcorg">RPB</mods:recordContentSource><mods:recordCreationDate encoding="iso8601">20200720</mods:recordCreationDate></mods:recordInfo><mods:identifier type="doi">10.26300/anjp-7w21</mods:identifier><mods:accessCondition type="rights statement" xlink:href="http://rightsstatements.org/vocab/InC/1.0/">In Copyright</mods:accessCondition><mods:accessCondition type="restriction on access">All rights reserved.
