supersaturation

[¦sü·pər‚sach·ə′rā·shən]
(meteorology)
The condition existing in a given portion of the atmosphere when the relative humidity is greater than 100%, in respect to a plane surface of pure water or pure ice.
(physical chemistry)
The condition existing in a solution when it contains more solute than is needed to cause saturation. Also known as supersolubility.

Inhibitors are substances which decrease the initiation of supersaturation, nucleation, crystal growth, rate of aggregation, or any other processes required to stone formation [34].
The deposition and condensation-freezing processes are related to the surface supersaturation relative to ice.
Therefore, the results presented in Figure 6 are of great importance for the development of CdS films with a desired thickness without any supersaturation solution phenomenon.
b) They might increase the supersaturation of solute at the ageing temperature.
CPP-ACP nanocomplexes located on the enamel surface have been purported to buffer the activity of free calcium and phosphate ions, thereby maintaining a state of supersaturation with respect to tooth enamel, preventing enamel demineralization, and promoting remineralization [13, 21].
The fluid was prone to rapidly reach saturation or supersaturation state during the reaction.
There were only modest decreases in calcium oxalate supersaturation and calcium but profound increases in stone protective factors like citrate (Table 1).
water composition, temperature, and supersaturation. At ambient temperature, calcite is the most predominant phase [12].
But with high enough partial pressures for carbon or nitrogen a relatively quick supersaturation with the interstitials can be achieved.
When the droplets of PMMA solution approached supersaturation, a very rapid phase change occurred to form a solid phase and PMMA precipitated on the surface of the fiber collector as electrospun beads.
During the day, the dissolved oxygen (DO) concentration established via photosynthesis can reach 300% to 400% supersaturation. At night, oxygen is rapidly consumed by aerobic degradation, resulting in anoxic conditions (Kayombo et al., 2002; Tadesse et al., 2004) and allowing several cyanobacteria genera, such as Oscillatoria, to dominate.
