16. Adaptations and constraints associated with autotrophy in microbial metabolism
Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER
17. Energy System Collaboration as a Vital Measure to Improve District Heating Performance
Sammanfattning : With joint commitments by twenty-seven countries under the Paris Agreement, the European Union envisioned a resource-efficient and competitive economy without net emission of greenhouse gases by 2050. Immediate and massive efforts across sectors of energy, industry, and buildings will be required, and district heating (DH), through its ability to integrate efficiency measures on the supply and demand side, can play a central role.

18. Polysaccharides from red and green seaweed : Extraction, characterisation and applications
Sammanfattning : Cultivation of seaweed has been conducted for centuries in Asia, but is largely undeveloped in Sweden even though there is potential for this industry. Seaweed offers benefits compared with land-based biomass cultivation. LÄS MER
19. Engineering and Functionalization of Hemicellulose Hydrogels
Sammanfattning : Hemicellulose is the second most abundant component in wood and is an important renewable resource that is used in films, paper composites and biofuels. Hemicelluloses have several advantages, including their abundance, degradability and renewability. LÄS MER
20. The Effects of Oxygenated Fuels on DISI Engine Particle Emissions and Efficiency : Experimental investigation of the effects of oxygenated biofuels on particle emissions and engine performance
Sammanfattning : The transport sector is one of the main sources of greenhouse gas emissions.Replacing fossil fuels with renewable fuels can help reduce the impact oftransportation on the climate. LÄS MER
