By changing the size of the emulsion droplets
, the scientists found that they could fine-tune the gels, including the temperature at which the nanoemulsions become a gel.
The finding should improve understanding of clouds and precipitation formation, as clouds with more vigorous turbulence could have a much stronger clustering signal, which in turn may influence the rate of the droplets
' collision in forming drizzle drops.
Using optical tweezers through highly focused laser beams, the team trapped and pushed together two protein droplets
floating in a liquid buffer solution.
But the droplets
that Zarzar and Goodling observed were not spheres, but rather, hemispheres or domes on a flat surface.
It is observed that at the zone of corona injection (2.5 cm position from either side of silicone rubber), the charge accumulation is high and a marginal reduction in magnitude of charge is observed with a single water droplet
. In the presence of two droplets
, the charge gets accumulated near the water droplet
than at the point of charge injection.
In the configuration presented here, the droplets
already move for AC voltages as low as [V.sub.rms] = 30 V, even without additional hydrophobic coating.

The evaporation process of PTFE colloidal droplets
on a rough substrate is shown in Figure 5.
The research objectives of this study are to determine the effects of vibrations as a mechanism to remove droplets
in dropwise condensation (Figure 1d).
In examining cleanability, several researchers tested the correlation of the thermodynamic model of adhesion forces between droplets
and substrates, using experimentally measured adhesion forces .
The reason for this is that there are no nozzles available that can produce droplets
For the flash boiling spray, the bubble growth in the superheated liquid increases volume of droplets
, decreases equivalent density, and then changes the Reynolds number and Weber number.
