1. Fullerene γ-Cyclodextrin Complexes
Abstract : The fullerenes, C60 and C70, can form inclusion complexes with .gamma.-cyclodextrin as the host. The complexes are formed by refluxing a water solution of . READ MORE

2. A Microcalorimetric Study of Macrocyclic Complexes in Aqueous Solution
Abstract : The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. READ MORE

3. Novel Gemini Surfactants Based on Natural Products Aggregation Behaviour in Aqueous Solutions
Abstract : There is currently much interest in using natural products to obtain novel types of surfactants. One of the reasons for increasing the proportion of surfactants based on natural products and replacing products based on petroleum raw materials is the growing concern about the environment.

4. Synergistic interactions involving amphiphilic polymers in solution
Abstract : The properties of hydrophobically modified cellulose derivatives in aqueous mixtures with various other molecules have been investigated. Mixtures of a hydrophobically modified polymer and alkali-sensitive, degradable surfactants gave rise to time-dependent viscosities. READ MORE

5. Hydrophobically Modified Polymers. Rheology and Molecular Associations
Abstract : Structure- property relationships and thickening mechanism in aqueous solution of two hydrophobically modified polymers (HM-P) with different architecture have been investigated. The two polymers, hydrophobically modified ethyl hydroxyethyl cellulose (HM-EHEC) and hydrophobically modified polyethylene glycol (HM-PEG), are commonly used as associative thickeners in the paint industry.
