Correlation between cellulose thin film supramolecular structures and interactions with water

Interactions between 4-thiothymidine and water-soluble cyclodextrins: Evidence for supramolecular structures in aqueous solutions

Since several years the inclusion of organic compounds (guests) within the hydrophobic cavity (host) of cyclodextrins (CDs) has been the subject of many investigations. Interestingly, the formation of inclusion complexes could affect the properties of the guest molecules and, for example, the influence of the delivery system can be a method to improve/change the photochemical behavior of the gu...

Thin Film Morphology of Block Copolymer Blends with Tunable Supramolecular Interactions for Lithographic Applications

A modular and hierarchical self-assembly strategy using block copolymer blends (AB/B’C) with tunable supramolecular interactions is reported. By combining supramolecular assembly of hydrogenbonding units with controlled phase separation of diblock copolymers, highly ordered square arrays or hexagonal arrays of cylindrical domains were obtained formixtures of poly(ethylene oxide)-b-poly(styrene-...

Water dispersible microbicidal cellulose acetate phthalate film

BACKGROUND Cellulose acetate phthalate (CAP) has been used for several decades in the pharmaceutical industry for enteric film coating of oral tablets and capsules. Micronized CAP, available commercially as "Aquateric" and containing additional ingredients required for micronization, used for tablet coating from water dispersions, was shown to adsorb and inactivate the human immunodeficiency vi...

Systematically Creased Thin-Film Membrane Structures

This paper presents a study of a square membrane, creased according to theMiura-ori folding pattern.When the membrane is allowed to expand from its packaged configuration, it initially expands elastically under zero corner forces. Starting from this naturally expanded configuration, the paper investigates the stress distribution and the load-displacement relationship when in-plane, diagonal loa...
