Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 [1] [2] as a way of predicting if one material will dissolve in another and form a solution. [3] They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.
Solubility parameter may refer to parameters of solubility: Hildebrand solubility parameter, a numerical estimate of the degree of interaction between materials, and can be a good indication of solubility; Hansen solubility parameters, developed by Charles Hansen as a way of predicting if one material will dissolve in another and form a solution
The Hansen solubility parameter (HSP) values [14] [15] are based on dispersion bonds (δD), polar bonds (δP) and hydrogen bonds (δH). These contain information about the inter-molecular interactions with other solvents and also with polymers, pigments, nanoparticles, etc. This allows for rational formulations knowing, for example, that there ...
In addition to over 130 published papers and 8 patents (h-index 25), he authored Hansen Solubility Parameters – A User's Handbook in 1999 followed by an expanded 2nd Edition in 2007. [6] With Abbott and Yamamoto he authored the package of software, eBook, and datasets called Hansen Solubility Parameters in Practice, in 2008 which is currently ...
This allows the prediction of polar and associative compounds, which most solubility parameter models have been found to do poorly. In addition to making quantitative prediction, MOSCED can be used to understand fundamental molecular level interaction for intuitive solvent selection and formulation.
If you've been having trouble with any of the connections or words in Sunday's puzzle, you're not alone and these hints should definitely help you out. Plus, I'll reveal the answers further down ...
Antibiotic use was not associated with an increased risk of cognitive impairment and dementia in healthy older adults, according to a recent study.
His 1924 monograph on the solubility of non-electrolytes, Solubility, was the classic reference for almost half a century. In 1927, Hildebrand coined the term "regular solution" (to be contrasted with "ideal solution") and discussed their thermodynamic aspects in 1929. A regular solution is one involving no entropy change when a small amount of ...
