Here's what I've gotten from the Sherdog report for HCF:
Nogueira beat Gouwenburg by TKO (strikes) at 4:34 of round 2.
Mousasi beat Santos by ref stoppage (strikes) at 3:42 of round 2. Said to be controversial stoppage, Santos didn't seem to be taking much damage on ground from strikes when the ref stopped it so it may have been a premature stoppage. Here's what Sherdog said:
Santos appeared to be doing a good job of dodging the blows while forcing Mousasi to constantly regain his balance before throwing strikes. It appeared that few of Mousasi's shots were doing any real damage but the referee thought otherwise and stepped in to stop the fight at 3:42 of the second round. Santos was up off the mat before Mousasi was to dispute the stoppage.
