Marangoni forces created by surface plasmon decay
TLDR
Spectral dependence of the plasmon decay length and control of optical beam characteristics are shown to provide a means for further manipulation of silicone oil and glycerol via surface tension driven forces sustained by surface plAsmon deexcitation energy.Abstract:
We present optical microfluidic manipulation of silicone oil and glycerol via surface tension driven forces sustained by surface plasmon deexcitation energy. The phonon energy associated with the decaying optically excited surface plasmons in a thin gold foil creates thermal gradients capable of actuating fluid flows. Spectral dependence of the plasmon decay length and control of optical beam characteristics are shown to provide a means for further manipulation.read more

Plasma Losses by Fast Electrons in Thin Films
TL;DR: In this paper, the angle energy distribution of a fast electron losing energy to conduction electrons in a thick metallic foil has been derived assuming that the conduction electron constitute a Fermi-Dirac gas and that the fast electron undergoes only small fractional energy and momentum changes.

How to make water run uphill.
TL;DR: A surface having a spatial gradient in its surface free energy was capable of causing drops of water placed on it to move uphill after an imbalance in the forces due to surface tension acting on the liquid-solid contact line on the two opposite sides of the drop.
