1. Atom probe tomography of Zircaloy-2 exposed to boiling water reactor operation
Sammanfattning : Zirconium alloys are used as cladding tubes for the fuel in nuclear reactors. In boiling water reactors (BWRs), the alloy Zircaloy-2, which contains the alloying elements Sn, Fe, Cr, Ni, and O, is commonly used. LÄS MER
2. Evolution of microstructure and nanoscale chemistry of Zircaloy-2-type alloys during nuclear reactor operation
Sammanfattning : Zirconium alloys are used as fuel cladding tubes in nuclear reactors. During reactor operation, these alloys are degraded by corrosion, hydrogen pickup (HPU), and radiation-induced growth, processes influenced by the alloying elements. LÄS MER
3. Turning waste into resources: Rethinking the way we discard things
Sammanfattning : Waste is one of the biggest challenges faced by our society. If not handled correctly, waste pollutes our natural environment with devastating results. However, it seems almost unavoidable that our society generates waste. LÄS MER
4. Sustainable Design and Control of Automated Material Handling Systems
Sammanfattning : An automated material handling system is a collection of electro mechanical components, electronics, and computer-based devices that act together to maintain flow of parts and materials in a modern production environment. Material flow is a significant factor in the design of manufacturing plants. LÄS MER
5. Extended Producer Responsibility for Closing Material Loops: Lessons from energy-efficient lighting products
Sammanfattning : The transition to a low-carbon economy requires enabling technologies including energy-efficient lighting products. It is increasingly recognized that a sustainable economy is not only low-carbon and energy efficient, but also resource efficient. LÄS MER
