1. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation
Sammanfattning : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. LÄS MER
2. Long-term properties of polyethylene films : efficiency of a natural antioxidant
Sammanfattning : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. LÄS MER
3. Health effects of heatwaves : short and long term predictions
Sammanfattning : Background: Climate change is defined by the Intergovernmental Panel on Climate Change as changes in the state of the climate associated with changes in the mean and/or the variability of its properties. Climate change will affect temperatures both as an increase in mean temperature as well as changes in the frequency of temperature extremes. LÄS MER
4. Quasi-instantaneous and Long-term Deformations of High-Performance Concrete with Some Related Properties
Sammanfattning : This report outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High-Performance Concrete, HPC, with some related properties. For this purpose about two hundred small cylinders and about one thousand cubes of eight types of HPC were cast. The age at loading varied between 18h and 28 days. LÄS MER
5. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources
Sammanfattning : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. LÄS MER
