11. Femtosecond Laser Microfabrication of Glasses and 2D Materials for Photonics and Energy Storage
Sammanfattning : Femtosecond laser-based fabrication technologies have seen rapid developments in the past decades, thanks to the capability of femtosecond lasers to induce localized multiphoton absorption in materials. Multiphoton absorption can result in various material modifications that can be leveraged for additive and subtractive manufacturing. LÄS MER
12. Learning from assessments of resource efficiency measures and their impact on resource use and the environment - Based on a case of additive manufacturing and a review of assessment studies
Sammanfattning : Resource efficiency measures have the potential to reduce the environmental and resource impacts of the current linear economy by decreasing the physical flows of material and energy associated with producing and using products and services. In order to investigate this potential, there is a need for assessments from a systems perspective, which for example enables the identification of possible trade-offs between different measures and aspects of resource efficiency depending on the product characteristics.

13. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites
Sammanfattning : Controlling the micro and nanostructure of materials is highly beneficial in order to tailor their physical properties. Extrusion-based 3D printing is a promising tool to produce hierarchical structures with controlled architecture. LÄS MER
14. Additive manufacturing of fused silica glass
Sammanfattning : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. LÄS MER
15. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments
Sammanfattning : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.
