two somewhat obscure interactions (question)

Hi, I was hoping someone who knows could answer this:

1. does mikael's remove Zed's R ?

2. can you interrupt yasuo's R with displacement? For example, If i command: shockwave yasuo while he is in the air ulting, will it interrupt his ult? I see it says once he arrives he just deals the damage (i.e. not over time)...so it seems pointless to interrupt it..? unless just to remove the CC

ty in advance
