a The schematic of the hydrogen bubble template electrodeposition method used to fabricate the microstructured Cu substrates. b The optical images showing the Cu substrates (C1 ~ C4) with different porosities, using the molarities of CuSO4 from 0.2 to 1.0 M, respectively. c The schematic of the setup to generate surface bubbles by surface heating and monitor their nucleation and growth processes. d The integrated instrument, ‘CubeLab’, developed by Space Tango for this project.
