2. 1. Crystallization in Constrained Polymer Structures : Approaching the Unsolved Problems in Polymer Crystallization

   Author : Eugenia Núñez; Ulf W. Gedde; Bernard Lotz; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystallization; Constrained structures; poly ε–caprolactone ; poly ethylene oxybenzoate .; Polymer chemistry; Polymerkemi;

   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

4. 2. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach

   Author : Hüsamettin Deniz Özeren; Mikael S. Hedenqvist; Richard Olsson; Fritjof Nilsson; Kim Bolton; KTH; []

   Abstract : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. READ MORE

5. 3. Advanced polymeric scaffolds for functional materials in biomedical applications

   Author : Kim Öberg Hed; Michael Malkoch; Eric Drockenmuller; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; hydrogel; PEG; dendritic monolayers; thiol-ene networks; off-stochiometric;

   Abstract : Advancements in the biomedical field are driven by the design of novel materials with controlled physical and bio-interactive properties. To develop such materials, researchers rely on the use of highly efficient reactions for the assembly of advanced polymeric scaffolds that meet the demands of a functional biomaterial. READ MORE

6. 4. Utilizing lignocellulose-based building blocks to develop recyclable polyesters

   Author : Nitin Valsange; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biobased; Polyester; Recycling;

   Abstract : With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. READ MORE

7. 5. Cellulose in quaternary ammonium hydroxide solutions

   Author : Shirin Naserifar; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quaternary ammonium hydroxides; cellulose; N; N-dimethylmorpholinium hydroxide; Triton B; NaOH; dissolution; TMAH; etherification;

   Abstract : An ever-increasing demand to shift away from fossil-based feedstock towards renewable resources has led to more use of bio-based materials. Cellulose being the most abundant biopolymer on Earth has received a considerable attention with a wide range of applications (in textile fibers, films, membranes, etc. READ MORE
