Neutrino- Donatello clips some of Splinter's fur. I get the impression it is to further analyze his DNA and learn more about their mutation. I don't think it would be just for sentimental reasons like a hair locket.

I like the reactions overall they had:

Spoiler:

- Michelangelo took a swim to distract himself and release energy. He also saw a regular turtle- I can imagine him thinking about how different he and his brothers are, and what would they have been without Splinter.
- Raphael released his tension by chopping all the wood.
- Donatello clipped the fur to immerse himself more in his scientific work.
- Leonardo is the one to give the eulogy and shoot the fire arrow to the pyre. He also is the last one to leave- he is crying at the end.
