1. Confined Fluid Flow: Microfluidics and Capillarity
Controlling and directing the flow within a microfluidic device is important for a variety of
applications ranging from self-healing devices to microfluidic diagnosis and analysis. The next
generation of advanced, adaptable materials will be multifunctional and hierarchical, and the ability to
move fluid within them will be vital to their functionality. In this short course, we will describe a
range of fluid phenomena occurring within confined environments. We will discuss an extension to
classical lubrication theory to account for the large gap changes within microchannels, describe
capillary action within various geometries, and introduce novel methods for internally controlling and
directing microfluidic fluid flow using elastic deformations.
2. Elastic Instabilities for Form and Function: Buckling, Wrinkling, Folding, and Snapping
Not long ago, the loss of structural stability through buckling generally referred to failure and disaster.
It was a phenomenon to be designed around, and rarely did it provide functionality. The increasing
focus on soft materials, from rubbers and gels to biological tissues, encouraged scientists to revisit the
role of elastic instabilities in the world around us and inspired their utilization in advanced materials.
Now the field of elastic instabilities, or extreme mechanics, brings together the disciplines of physics,
mechanics, mathematics, biology, and materials science to extend our understanding of structural
instabilities for both form and function. This short course will examine the fundamental mechanics of
buckling plates and shells, and demonstrate how these instabilities can be harnessed to create
metamaterials, pattern surfaces, and morph structures.
Tutti gli interessati sono invitati a partecipare.
