1. Norbornadienes for Solar Thermal Energy Storage and New Applications
Sammanfattning : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.

2. Conjoined piezoelectric harvesters and carbon supercapacitors for powering intelligent wireless sensors
Sammanfattning : To achieve total freedom of location for intelligent wireless sensors (IWS), these need to be autonomous. To achive this today there is a need of broadband piezoelectric energy harvesting and a long-lasting energy. The Harvester need to be able to provide sufficient amount of energy for the intelligent wireless sensor to perform its task. LÄS MER
3. Degradation mechanisms and long-term performance of PUR insulation in district heating pipes
Sammanfattning : District heating networks are used worldwide, especially in Scandinavian countries and also in many other countries, e.g. Germany, Russia, United States, South Korea and China. From an environmental point of view, district heating networks are a good alternative to more traditional building heating systems. LÄS MER
4. Biomass Energy Systems and Resources in Tropical Tanzania
Sammanfattning : Tanzania has a characteristic developing economy, which is dependent on agricultural productivity. About 90% of the total primary energy consumption of the country is from biomass. Since the biomass is mostly consumed at the household level in form of wood fuel, it is marginally contributing to the commercial energy supply. LÄS MER
5. CO2 Separation with Ionic Liquids -Property, Gas solubility and Energy consumption
Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as liquid absorbents for CO2 capture because of its advantages, such as non-volatility, functionality, high CO2 solubility and lower energy requirements for regeneration. A significant amount of research has been carried out, but most of them are on the synthesis of novel ILs and the measurements of CO2 solubility in ILs. LÄS MER
