1. Synthesis and characterization of lactic acid-based elastomers
University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomiAbstract : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

2. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.
University essay from Karlstads universitetAbstract : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. READ MORE

3. Material Characterization for the Simulation of Drop Tests Against PMMA Sheets
University essay from Jönköping University/JTH, Material och tillverkningAbstract : There is a high demand for implementing simulations in the design and product devel-opment processes, avoiding the execution of costly tests on prototypes and giving thechance of discarding unsuitable designs, as well as exploring possible ones without much cost added.This project assignment is to find a suitable way to simulate drop tests on two typesof PMMA sheets, a material widely used on luminaire covers.

4. Negative energy elasticity and a model for the behavior of the residual strain in doubly cross-linked gels fabricated by shear strain
University essay from Uppsala universitet/PolymerkemiAbstract : Doubly cross-linked gels were fabricated based on tetra-poly(ethylene glycol) (Tetra-PEG) by shear strain. These are gels with two network structures present in the same polymeric network. The second network structure is introduced by applying a mechanical field to the first natural network structure.

5. Numerical Study of Polymers in Turbulent Channel Flow
University essay from KTH/MekanikAbstract : The phenomenon of drag reduction by polymers in turbulent flow has beenstudied over the last 60 years. New insight have been recently gained by meansof numerical simulation of dilute polymer solution at moderate values of theturbulent Reynolds number and elasticity. READ MORE
