1. 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

2. Functionalization of Synthetic Polymers for Membrane Bioreactors
Abstract : Membrane bioreactors (MBRs) show great promise for productivity improvement and energy conservation in conventional bioprocesses for wastewater reclamation. In order to attain high productivity in a bioprocess, it is crucial to retain the microorganisms in the bioreactors by preventing wash out. READ MORE

3. Structure-Performance Relations of Oxygen Barriers for Food Packaging
Abstract : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. READ MORE

4. Rheological and mechanical properties of systems containing nanocellulose
Abstract : Nanocellulose is a cellulose entity at the nanoscale. There are several different types of nanocellulose such as cellulose nanofibrils (CNF), which are long, somewhat flexible fibrils and cellulose nanocrystals (CNC), which are shorter and more rod-like particles. READ MORE

5. Biomolecule Trapping With Stimuli-Responsive Polymer Coated Nanostructures
Abstract : Trapping biomolecules in nanosized gaps is of great interest in novel systems for single molecule analysis and membranes, which filter biomolecules. Current platforms are lacking in full functionality to facilitate biomolecule trapping and transport in their native environment and without covalent tethering to surfaces. READ MORE
