Below is a complete list for the locations of all minikits in Chapter 10: Lost in the Aether.
Part A MInikits
Minikit #01: Head to west cell and hypnotize the person there. He will step on a pressure switch, while you stand on the matching one outside. Go inside the cell and break the toilet to get this minikit.
Minikit #02: Bust up the stuff in the room between the stairs and create a speed pad from the pieces. Make use of this to snag the bricks for this collectible and put it back together.
Minikit #03: Before heading the room where Sif is, fly Thor to the to-left corner of the stairwell to collect this minikit.
Minikit #04: Use a scanner at the entrance to Sif's room then create a Deflection Pad. Have a shield-wielding person (like Cap) to deflect the enemy's projectiles at it until defeated.
Minikit #05: Send someone with a scanner to the wreckage site of the dark elf ship. Access the S.H.I.E.L.D. terminal that appears and it will give you the bricks needed to rebuild this collectible.
Part B MInikits
Minikit #06: At the starting area of the Svartalfheim, send Ultron to the rear section of the area and smash the object there to get this collectible.
Minikit #07: Send someone with a scanner to check along the eastern section of the area to uncover a dig spot. This minikit is buried under there.
Minikit #08: Send someone who can use lasers onto the platform Kurse was on, and destroy the gold rock there.
Part C MInikits
Minikit #09: Check behind the burning wreckage of a helicopter to find a rock you can destroy. Do so and use telekinesis on the object to get this collectible.
Minikit #10: Search for a phone booth off to the western section, and have Hawkeye open it for this level's final minikit.
