MORE ABOUT THE INTERVIEWEE :
Kari Dalnoki-Veress has been a Professor at McMaster University, Ontario, since 2010. There, he leads the Dalnoki-Veress Lab, a research group that studies experimental soft matter, and in particular the properties of polymers and living systems.
The topics he has worked on range from the mechanical properties of nematods like C. Elegans, to the glass transition of polymers, but also include elastocapillarity in fibers and films of polymers.

Wow, the ability to use droplets to manufacture micro or maybe even nanoscale coils is going to have a huge impact on a lot of industries.
Very underrated channel
Fascinating. The folding, coiling and flattening reminds me of a protein folding study I read that found proteins required water in order to fold. Also another that showed the temperature changed the way proteins folded. The fact that water expands upon freezing and can change from a soft to hard surface makes its properties in this context mind boggling. :) Great video.
Simply amazing video ! Very excited to see more such videos !
amazing to watch
Could do this with nanofibers of copper to make very tiny inductors
I am interested to know application part of this phenomenon. And thanks for this beautiful video.
So beautiful. Thanks for sharing.
Simply amazing !!!👌👌👌
Keep up the good work! 👍
Nice 👍 work!
the name of the is just great and fun. Thanks a lot
MOAR!
Pls.
All your videos are great! I really enjoyed watching them. Thanks a lot.
awesome!!!
That bald jokes lol
12:32 it certainly does :P
crazy stuff!
If you are last year PhD student or PostDoc and you discover something unexpected and cool outside your Research project, DO NOT share it with your Supervisor. Keep it for your self and built your own research line from there 😁.
i still don't get it, why hasn't this gone viral
Camille Duprat..at least one familiar name.
REMARKABLE. AWESOME. UNBELIEVABLY FOR FREE AND ALL only the scientific information density of the video is kinda .. meh
if you can, grow a beard
