6. Mass Transport Through Polymer Films: The Importance of Interfaces and Compatibility
Abstract : Different types of barriers are used in packaging to keep and protect products from the surrounding environment and are often essential for storing and transportation. Today, many barriers are made of different types of polymers, but since most polymers do not exhibit desired barrier properties on their own, combinations must be used. READ MORE

7. Crystallization in Constrained Polymer Structures : Approaching the Unsolved Problems in Polymer Crystallization
Abstract : The knowledge regarding certain issues in polymer crystallization e.g. the possible existence of short–lived mesophases remains inconclusive due to experimental limitations. Polymers undergo chain folding upon crystallization, which introduces some complications that are not found in crystallization of low molar mass materials. READ MORE

8. Poly(N-Isopropylacrylamide) Polymer Brush Functionalized Nanostructures as Thermo-Responsive Gating Systems for Protein Transportation
Abstract : Controlling molecule translocation through nanosized gaps is of great interest in novel systems for single molecule analysis and biomolecular membranes. The molecular gating property of thermo-responsive end-grafted poly(N-isopropylacrylamide) (PNIPAM) polymer brushes on well-shaped gold-silica nanostructures is intended to be investigated for controlled protein transportation via extinction spectroscopy and fluorescence microscopy methods below and above PNIPAM lower critical solution temperature (LCST; 32 °C in water).
