The observed effect may well be due to electrical discharge
between water droplets.
However, plant leaves and biofilms both vary in this respect: when the lotus effect is present, small air bubbles are trapped
between the water droplet and the surface of the leaf, whereas this does not occur in the rose petal effect.
Not exact matches
Oil dispersant is that dish soap, lowering the tension
between oil and
water and allowing small
droplets of oil to break away from the larger clumps.
A team at the University of Nottingham used a simulation that matches experimental and in situ observations to characterize ice on a spectrum
between rime ice that forms from
water vapor and glaze ice that forms from supercooled
water droplets.
It increases the repulsion
between the
water and glass, causing the
water to form
droplets.
As the
water naturally evaporates, the vapor fills the area in
between the pillars below the
droplet, building pressure.
Protocells made from oil
droplets in
water allow soluble chemicals to be exchanged
between the drops and their surrounding solution.
Representations of glitches and distortions in paintings of mutated poppies and
water droplets suggest the presence of a hidden screen
between the viewer and the image, and test the limitations of living in a digital reality.
Moonbows are natural atmospheric phenomena that occur by the interaction
between sunlight reflected off the surface of the moon and
water droplets suspended in the atmosphere
Recent experimental work at CERN supports an hypothesis that solar magnetic activity throttles formation of cloud
water droplet condensation sites and this then explains the correlation
between solar magnetic minima with cold epochs.
The study found a positive correlation
between low altitude cloud amounts and dust at the coast of North Africa, which supports the theory that dust particles act as a place for
water droplets to form around in thin low clouds.
Because of the different intramolecular forces
between water molecules as vapor in air,
water, and ice, the wavelengths of emission and absorption are shifted; some of the radiation from the
water / ice
droplets at the top of a cloud can escape to space because the atmosphere above it is transparent at its wavelengths, whereas the same radiation from
droplets at the bottom of a cloud will be absorbed and re-emitted in random directions from the
droplets above, including back down to the originating
droplets.
