Abstract

<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgj411n9sj" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />Evaporating droplets of both PEO polymer solutions and blood at low pressure are observed to form pillar-like deposits when dried. We use normalised <italic>h</italic>–<italic>R</italic> plots to illustrate that this behaviour is volume-independent and find scaling arguments to support our measurements that the contact line recedes with a speed inversely proportional to the droplet radius.</p> </abstract>
