For example, reformulation of the Köhler equation was suggested to consider the effects of soluble gases and slightly soluble solid substances in the droplet nucleation process (Laaksonen et al. 1998).
Individual stock solutions for all analytes were prepared by dissolving the solid substance in acetonitrile.
Individual stock solutions of the standards were prepared by dissolving the weighted solid substance in acetonitrile, or, if insoluble, either in methanol, acetonitrile/water (50 50, v/ v), methanol/water (50 50, v/ v) or pure water.
Chemical precipitation, formation of a separable solid substance from a solution, either by converting the substance into an insoluble form or by changing the composition of the solvent to diminish the solubility of the substance in it.
Compounds were prepared by weighing the solid substances to 1 mg.mL-1 in ACN.
The solid of the mathematicians, according to Desgabets, consists in a magnitude that has three dimensions, i.e., length, width, and thickness while the natural body of the physicist consists in a solid substance extended in three dimensions.
The product was crystallized and dried in a vacuum drier, producing a white solid substance with melting point in the range of 57.5 °C to 61 °C.
Solid substances were dissolved in pure methanol (D3S, D15S) or acetonitrile (DON, D3G) and stored at −20 °C.
The mass transfer processes, internal and external one, should be incorporated in designing SCWO processes for solid substances and related processes such as catalytic SCWO.
In 1916 he showed that solid substances could be used in powdered form for X-ray study of their crystal structures, thus eliminating the difficult step of first preparing good crystals.
But embedded in a matrix of water molecules, sand particles stay in place, somewhat like molecules in solid substances.
