Microwave Dielectric Heating of Drops in Microfluidic Devices [PDF]

, 2009
We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent molecular dipole moment that has ...

Where is the chromospheric response to conductive energy input from a hot pre-flare coronal loop? [PDF]

, 2014
Before the onset of a flare is observed in hard X-rays there is often a pro- longed pre-flare or pre-heating phase with no detectable hard X-ray emission but pronounced soft X-ray emission suggesting that energy is being released and deposited into the ...

Thermal stability of cold clouds in galaxy halos [PDF]

, 1999
We consider the thermal properties of cold, dense clouds of molecular hydrogen and atomic helium. For cloud masses below 10^-1.7 Msun, the internal pressure is sufficient to permit the existence of particles of solid or liquid hydrogen at temperatures ...
