1. The new ETH PoW coin still have smart contract active?
Yes, the merge is just a change of consensus. And ETHW communities are the ones who maintained the PoW consensus, a.k.a decided not to merge/change the consensus. So, smart contact is still possible on both cryptocurency.
2. Are there projects still running on ETH PoW instead of the new ETH PoS?.
Projects that previously runs on ETH pre-merge will automatically adapt or follow to the change of consensus, so all apps/platforms are now running on ETH post-merge.
The current ETH and ETHW(Ethereum PoW) is a different subject of cryptocurrency, it is unrelated. The majority of ETH communities are staying their way within the current PoS chain, whereas ETHW is a wholly different subject since some communities are forking their own network.
