The investigation of ion-aggregate formation based on conductivity studies can be extended to quadruple-ion formation [108-111], which is thought to be the reason for the conductivity maximum and the subsequent decrease of conductivity. 

Na is likely deposited in the upper atmosphere by meteors along with other metals (Clemesha et al., 1981) and distributed by solar winds (Happer et al., 1994). This atomic layer is "eaten away" at its bottom by chemical reactions (e.g. molecule and aggregate formation). Fe, Al, Ca are more abundant than Na, but the D2 transition is so strong that it provides the largest product of column density CNa and transition cross section, nominally 10 — 10" atoms/cm. The layer has been studied mostly with Lidar technique (Blamont and Donahue, 1961 Albano et al., 1970 Bowman et al., 1969 Sarrazin, 2001). 

Hydrophobic interaction chromatograph (HIC), while very attractive in principle, has proved difficult to scale up for processing. A recent series of articles explores some of the unique problems associated with process-scale HIC. Load sample preparation20 must be carefully examined to prevent protein aggregate formation in the presence of the relatively high salt concentrations used in this technique. Successful scale-up also requires the setting of wide specifications to accomodate routine variations in the feed.21 The effect of the salt concentration on capacity may be somewhat more...

Shrinking of the polymer chains as a function of temperature was observed by capillary viscometry. The reduced viscosity, r]Sp/c, of polymer solutions approaches zero when the polymers are in their fully collapsed compact state and flow freely through the capillary. Above the cloud point, rjSp/c increases, which is indicative of aggregate formation. At low temperatures the... 

Incorporation of the dyes into host matrices raises concerns about achievable concentration, aggregate formation, and migration fastness.
