Episode 384 - "Glaciers caused the great lakes, now we have them, the end" Alexis Dahl

This week we see how scientists break down the Earth into 7 or more spheres and why that is and isn't a good idea. We also explore a fun paper about graphene that is just full of crap.

Fun Paper Friday


Graphene is an amazing material, but are all of the papers about it full of crap? This one certainly is!
Wang, Lu, Zdenek Sofer, and Martin Pumera. "Will any crap we put into graphene increase its electrocatalytic effect?." ACS nano 14.1 (2020): 21-25.
