Swing-like pool boiling on nano-textured surfaces for microgravity applications related to cooling of high-power microelectronics

Cooling microelectronics with nanofibers As microelectronics get smaller, there is an urgent need to develop efficient methods to keep them cool without extra power input. Under normal gravity, excess heat can be removed by vapor bubbles rising through a coolant. In space however, due to the lack bu...
