Sentences with phrase «for nucleating»

At supersaturated atmospheric conditions, bare and coated particles had a nearly equivalent predisposition for nucleating ice.

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.
The formation of neutral (i.e. uncharged) nucleating clusters of sulfuric acid and dimethylamine was observed for the first time.
Led by PNNL, the cross-functional research team, working under a measurements - to - modeling paradigm, investigated the ice nucleating properties for different dust samples affected by another kind of pollution.
«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.
In the longer term, Revive aims to nucleate an even larger scale effort that will bring together an expanding number leading scientists, clinicians and biotechnology companies into a national Consortium for stem cell - based regenerative medicine and drug screening.
According to Christner, agricultural losses from ice nucleating bacteria, such as Pseudomonas syringae, often exceed $ 1 billion dollars per year in the United States, so understanding their mode of dispersal is essential for mitigating their impact on crops.
Oskar protein, which contains LOTUS and SGNH - hydolase - like domains, nucleates formation of germ granules, RNP complexes containing RNAs and proteins essential for germ cell formation and function.
# 15/16 Heavy deluges [what else to expect with 4 % more vapor in the air and enough nucleating dust and MM aerosols] are accounting for an est. 6 mm drop since winter 2010.
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.
Well, to make it work, the mechanism needs clean air (which you always had over at least parts of the oceans) and nucleating aerosols (e.g., as you get from DMS, which is primarily formed by phytoplankton which exists for a loooooong while), so yes, it is reasonable that the mechanism has been operational, though quantitatively it may have changed somewhat.
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.
Some of the work at CERN seemed to say that cosmic rays nucleate very small droplets that do not increase to cloud size... Anyway, some of us follow GCR for reason of climate amplifications and even Ozone hole development.
When endothermic reacting (toxic) ice nucleating materials are utilized on a massive scale for climate intervention / modification programs, convection is greatly impacted, too many condensation nuclei are present, and precipitation is generally greatly reduced (from what it would have otherwise been) in the core of the engineered chemical cool - down zones.
