SUMMARY:ICFO | SANDER WOUTERSEN
CLASS:PUBLIC
DESCRIPTION:Particles that consume energy to move (&ldquo\;active matter&rd
 quo\;) are a hot topic in soft-matter physics. Experimental work has focus
 ed mostly on point-like particles\; for active polymers\, there is plenty 
 of theory and simulations\, but hardly any experiments\, probably because 
 active polymers are difficult to synthesize. As an easy alternative\, we h
 ave done experiments on ensembles of long\, thin worms (Tubifex) that beha
 ve as active polymers. In this informal talk\, we will discuss the rheolog
 y\, phase separation\, and chromatography of these active-polymer worms (t
 his last idea was awarded the IgNobel prize for chemistry). We will also d
 iscuss some practical aspects\, such as how to anaesthetize a worm\, build
 ing a worm-chromatography setup in your living room\, and the importance o
 f aquarium shops for fundamental research. Please bring your phone: the ta
 lk will contain an online quiz and you can win a prize!
