Sentences with phrase «nucleate water»

«We found that exposing particles to sunlight makes the particles increasingly more oxidized and acidic, which in turn makes it easier for such particles to nucleate water and make cloud droplets,» said Professor Sergey Nizkorodov, a physical chemist at UCI who led the study.

Not exact matches

For bulk water samples, these conditions are described as «no man's land,» because ice nucleates before such temperatures can be reached.

Vonnegut went on to invent what amounted to a nucleating machine: He dissolved silver iodide in acetone, sprayed the solution through a nozzle to make droplets, and then literally burned the droplets, producing trillions of nuclei; under the right conditions, each could form the core of a drop of water or flake of snow.

This study offers insights into how chemical building blocks — glyoxal, water, and hydrogen peroxide — chain together, or nucleate, to form materials.

Ice - nucleating bacteria — which have been referred to as «rain - making bacteria» — may be significant triggers of freezing in clouds and influence the water cycle.

This was an experiment which aimed to test the hypothesis that cloud seeding with silver iodide could suppress hail by creating an excess of nucleating embryos that would compete for the available cloud water (and thus keep all the hydrometeors smaller)-- more precipitation, in fewer big «globs» of hail.

In addition, many non-sulfur-based biogenic materials of the terrestrial environment play major roles as water - and ice - nucleating aerosols; and the airborne presence of these materials should also be enhanced by rising levels of atmospheric CO2.

In a process called cloud seeding, silver iodide, with effective ice - nucleating temperatures of less than − 4 °C, has been used for years in attempts to convert supercooled water to ice crystals in regions with a scarcity of natural ice nuclei.

'' The freezing / melting point of pure water is 0C» Sorry if someone else has already raised this point, but when I lived in Alberta it was repeatedly inculcated that without a nucleating agent, pure water did not freeze until about -39 C. Maybe this is only of biological importance (0C melting point is ok), but I think you need to be more precise.

Since super cooled water doesn't magically nucleate when you might expect, based on Boltzmann, perhaps a little creativity could be a wonderful thing.
