In terms of the basic character of the intermediate filament fiber, it is an apolar
structure because the two dimers come together in antiparallel fashion to form a tetramer.
Therefore, the apolar
and polar surface tension parameters are influenced by the nature and composition of solvent/nonsolvent mixtures from which the films had been prepared.
Note: RI (a) and RI (b): retention indices relatives to n-alcanes, on (a) apolar
column (HP-5) and (b) polar column (HP-Innowax).
[RP.sub.18], precolumns (Merck) were used to protect the column from apolar
ingredients of biologic material.
On the other hand, the presence of apolar
methylene and methine groups in the backbone and the ring conferring hydrophobic properties cause the opposite effect over the release process.
adolescentis activity, while the apolar
substituent groups of methyl and methoxyl in chrysophanol and physicion might play a weakening role on antibacterial activity.
Originally, for the MAn-g-IIR, the driving force for the formation of these aggregates is due to the large polarity difference between the polar anhydride groups and the apolar
Interactive use of linear retention indices on polar and apolar
columns with an ms-library for reliable characterisation of Australian tea tree and other Melaleuca sp.
This is probably related to the strong hydrophobic character of the clay that permits a high compatibility with the apolar
2008), Brazilian cherry oil was submitted to this methodology and showed that the most apolar
fraction (obtained with pentane) gave hydrocarbon sesquiterpenes and furano-sesquiterpenes in 56% (w/w).
One of the most widely used nucleating agents is the so-called "clarifier," dimethyl dibenzylidene sorbitol (DMDBS), which is the latest generation benzylidene sorbitol derivative (11), DMDBS is a butterfly-shaped molecule that hydrogen bonds in apolar
matrices to form crystalline nanofibers, on whose surface polymer crystallization is nucleated (12).
It is interesting to note that compound 3 is the most apolar
