Biopolymers
The overall objective is to obtain new polymers based on hemicelluloses derived from the Risø bioethanol process. Hemicelluloses are part of the lignocellulosic stream that is fermented in a multi-step process to generate bioethanol. However, the hemicelluloses are not necessarily all utilized in this process and may be available for other high-value uses. One possibility is to chemically modify these carbohydrates to make them more amenable to further processing (e.g., extrusion). |

Advances in sustainable materials - Chemical and physical modification of hemicellulose sugars
The overall objective of the project is to produce films from hemicellulose, which may potentially be used as food packaging materials. Composite films from hemicellulose and nanoscale fillers will be produced in parallel to films from chemically modified hemicelluloses. Improvement in barrier and mechanical properties relative to native hemicellulose film will be the target. |

Novel polylactide-cellulose bio-nanocomposites
The overall objective of this project is to develop microfibrillated cellulose fibre (MFC) reinforced polylactide (PLA) biopolymer nanocomposites via an industrially practical method. We would like to explore novel ways of combining positive feaures of PLA and MFC and thereby obtain nanocomposite materials with superior properties. |

Artmus - Artificial Muscles
Risø, DTU and Danfoss A/S conducts a research and development project aiming at developing linear actuators based on polymeric materials. Such an "artificial muscle" will supply the force for a mobile system similar to the action of striated muscles in the body. |

New polymer materials for organic photovoltaics
Organic photovoltaic have shown promising results for efficiency and stability. Recently printing of the organic layer has also been studied. However, these results have not been demonstrated for the same polymer material. Hence, the challenges today for the organic photovoltaic research area are to combine the three properties: efficiency, stability and processing in one material. |

Stable Photovoltaic Materials: Physics and Characterisation of Organic Solar Cells
While efficiencies approaching 5% have been achieved for organic solar cell devices with theoretical prediction of more then 10%, the short operational stability still remains one of the key issues of polymer photovoltaics. |

Polymer solar Cells introduction
Solar cells are one of the most promising devices in search of sustainable renewable sources of energy. Although silicon cells based on solid-state p-n junction devices have dominated the field, new generations of photovoltaics are emerging. |

Catalytic Systems for CO2 Fixation and Photo Reduction to Combustible Fuel
The project explores catalytic systems for fixation of atmospheric carbon dioxide followed by photo reduction using water to give liquid or solid, storable carbon dioxide neutral combustible fuel for remote consumption. The rising demand for energy and the extensive use of energy technologies that increase the global CO2 emission has lead to the proposition of new energy platforms such as hydrogen technologies. |

Stable Polymer Photovoltaic Materials
Polymer solar cells (plastic solar cells) have seen remarkable improvements in recent years where power conversion efficiencies of up to 5% have been reported for small area devices (1-10 square millimetres). In terms of lifetime however polymer solar cells have been remarkably poor in performance with lifetimes of 1-2 weeks. During an ongoing study at Risø (supported by DSF) on the subject of understanding the degradation properties a new class of materials with exceedingly long device lifetimes was discovered. |
