1. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products
Sammanfattning : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. LÄS MER
2. Guiding Sustainability Transitions: Backcasting, Experimentation and Social learning
Sammanfattning : Sustainability challenges including climate change, social injustice, resource depletion and biodiversity loss are becoming increasingly apparent. These challenges can be understood as partly resulting from unsustainable socio-technical systems in society, assumed to require transitions to become sustainable in time. LÄS MER
3. Techno-Economic Perspectives on Biofuel Futures – Modelling Transport Sector Strategies in an Energy System Context
Sammanfattning : The high oil dependence and the continuous growth of energy use in the transport sector have in recent years triggered interest in transport biofuels as a measure to mitigate climate change andimprove energy security. This work aims to examine techno-economic interactions linked totransport biofuel strategies in national and regional energy systems and their implications for thecost-effective realisation of energy policy objectives.

4. All-organic aqueous Na-ion energy storage devices
Sammanfattning : Development of all-organic aqueous energy storage devices (ESDs) is a promising pathway towards meeting the needs of technically medium/low-demanding electrical applications. These ESDs should favour low cost, low environmental impact, and safety, and thus complement high voltage and energy/power dense storage such as lithium-ion batteries. LÄS MER
5. User-Centred Design and Technology-Mediated Services- Identifying and Addressing Challenges by Analysing Activities
Sammanfattning : User-centred design has a focus on designing products to satisfy user needs rather than emanating from a technological starting point. Understanding user needs when developing products is considered a key component to achieve market success today.User-centred design is almost always described as a way to design products that satisfy user needs.
