16. Building blocks for polymer synthesis by enzymatic catalysis
Sammanfattning : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. LÄS MER
17. Synthesis and Characterization of Self-Assembling Low Molecular Weight Copolymers for Bioengineering Applications
Sammanfattning : The constant need for improved biomedical materials and the interest in producing materials with similar properties to the extracellular matrix in different tissues has resulted in increasing interest in research on hydrogels. Over the last decade self-assembling copolymers have been of particular interest since they form hydrogels in response to external stimuli such as temperature. LÄS MER
18. Synthesis and Characterization of Acceptor Polymers for All-Polymer Solar Cells and Photodetectors
Sammanfattning : The development of polymer semiconductors has become an important topic due to its advantages of low cost, easy fabrication, light weight, and capability to fabricate flexible large-area devices. For example, as the need for new clean energy sources is increasing, polymer solar cells (PSCs) are being developed rapidly and becoming a promising alternative to silicon solar cells. LÄS MER
19. Chemical Modification of Electrospun Cellulose Nanofibers
Sammanfattning : The forest industry is a large part of the Swedish economy and the export of pulp, paper and wood products constitutes 11% of the total Swedish export of goods. The main product of a pulp mill is purified cellulose, which has many great properties like biodegradability and non-toxicity. LÄS MER
20. Utilizing lignocellulose-based building blocks to develop recyclable polyesters
Sammanfattning : 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. LÄS MER
