We present our latest experimental results on ultracold NaK quantum gases, focusing on atom-molecule and molecule-molecule collisions. In particular, we report recent advances in the electric field control of atom-molecule Feshbach resonances and shielding of collisions with implications for future quantum simulations and many-body physics.
