Peptides complexed to cyclodextrin fragment rather than dissociate when subjected to blackbody infrared radiation
Article Abstract:
The fragmentation behavior of peptide-cyclodextrin complexes has been studied through blackbody infrared radiation dissociation. The peptides used in the research are bradykinin, (Lys1)-bradykinin, GGBK, dR1BK and dR9BK. Results indicate that complexes formed by mixing bradykinin with permethylated beta-cyclodextrin undergo peptide fragmentation instead of dissociation. This finding suggests covalent bond cleavages are more common than complex dissociation under blackbody radiation conditions.

Rheological properties of a telechelic associative polymer in the presence of [alpha]- and methylated [beta]-cyclodextrins
Article Abstract:
The rheological properties of aqueous hydrophobic ethoxylated urethane (HEUR) solution are examined in the presence of [alpha]-cyclodextrin ([alpha]-CD) and m-[beta]-CD. The effect of temperature on the interaction of unmodified [alpha]-CD/poly(ethylene oxide) (PEO) and hydrophobe/[alpha]-CD systems is examined and compared to those of m-[beta]-CD/PEO and hydrophobe/m-[beta]-CD.

Enhanced hydrophobicity of rough polymer surfaces
Article Abstract:
The effect of periodic roughness of polyethylene (PE) and poly(vinyl chloride) (PVC) polymer surfaces on the hydrophobicity is analyzed by using molecular dynamics simulations. It is found that the difference between the water contact angles on the flat PE and PVC surfaces has led to different equilibrium wetting geometries on pillar structures of approximately the same size.
