41a Offend monarch and die (4)

2d Old Australian engineer raised capital (6)

34d Possibly Hardy's secret mistresses (5)

Looks like:

SIN K (no extra word) [not too happy about 'monarch' = K, but there we are]

O + (A WATT)< (no extra word)

AMIES [ref Hardy Amies] (extra word 'secret')

41a ... possibly sink?

Thank you jack natter and marca

Hints on these two.

5a. Gates in tracks around Newnham College overturned (7)

1d. Designs of prophet Nostradamus end in chaos (7)

Thanks.

1d Mosaic (relating to Moses)s Extra word is Nostradamus

It's definitely 'Gates' rather than 'Grates'?

Thanks marca.
I had thought of mosaics but mosaic meaning of Moses eluded me.

Thanks jacknatter.
My mistake.
It is
Grates in tracks around Newnham College overturned (7)

Then it's a 6-letter plural noun meaning 'tracks' containing a 1-letter abbreviation for 'college', all reversed, giving a (dialect) word meaning 'grates'. 'Newnham' is superfluous.
