Rifamycin B resolved several racemic amino alcohols, such as atenolol, alprenolol, ephedrine, norphenylephrine, salbutanol, terbutaline, and others (212). The charge-charge, hydrogen bonding, and hydrophobic inclusion interactions between the negatively charged rifamycin and the amino alcohol provide chiral... 

In the cases, where the anion does not differ greatly in its size from the water molecule (especially, in the direction of increasing), i.e. where the anion-water edge, formed during the hydrophobic inclusion, does not differ significantly from that in pure water structure,... 

Hydrophobic inclusion variants. The diversity of polyhydrate forms (both differing in composition and having the same composition) may be related not only to different framework structures. Within the same framework structural type hydrates with different compositions can exist, this depending on the way of the guest inclusion. 

The diguanidinium tetrakis( 6-cyclodextrin) tetrapodal 60 is a suitable host for different nucleotides. 60 interacts with adenosine derivatives by combining the unspecific hydrophobic inclusion of the nucleobase with the electrostatic guanidinium-phosphate interaction. Nucleotide receptor stoichiometries of 2 1 were obtained with binding constants approaching 10 M for the complexa-tion of disodium 5 -adenosine triphosphate, monosodium 5 -adenosinediphosphate, and monosodium 5 -adenosine-monophosphte. 

WETTING FILMS ON LOCALLY HETEROGENEOUS SURFACES HYDROPHILIC SURFACE WITH HYDROPHOBIC INCLUSIONS... 

In view of the preceding features, we can say that the presence of more hydrophobic spots on smooth hydrophilic substrates results in the formation of depressions where the film thickness is lower than the thickness on the rest of the substrate. Accordingly, the presence of more hydrophobic spots results in a lower mean thickness of the film relative to the thickness on a uniform hydrophiUc substrate. Thus the surface roughness and the presence of hydrophobic spots on the surface influence the mean thickness of the equilibrium film in opposite ways the presence of roughness results in an increase in the mean film thickness (Section 2.5), whereas the presence of hydrophobic inclusions leads to the contrary.
