Sentences with phrase «stable clusters»

The data collected indicate that the electrons released by the cosmic rays acted as catalysts to accelerate the formation of stable clusters of sulfuric acid and water molecules — the building blocks for clouds.

One cell, the mother cell, keeps an old cell pole that originated in a past division, where efflux pump proteins have formed stable clusters.

Comparing the classical and novel view, it is furthermore crucial to note that a distinct part of the nucleation driving force given by the change in Gibbs energy is already released by stable cluster formation (SOM section 2.6, fig.

The heat rips the CO arms off the iron atoms, leaving the lone atoms energetically unhappy and eager to bond with one another to form more stable clusters.

In contrast, there is increasing evidence that small polymeric species and stable clusters play a dominant role in the prenucleation stage of biomineralization and the formation of organic nanoparticles (16, 17).

Stable clusters are the relevant species in calcium carbonate nucleation.

Even younger than open clusters, stellar associations are very loose groupings of young stars that share a common place and time of origin but that are not generally tied closely enough together gravitationally to form a stable cluster.

The H2SO4 can then condense together with water vapor (and perhaps organic compounds and / or ammonia) to form a stable cluster of molecules: A new particle is typically 1 - 2 nanometers in diameter.
