1. 11. Modeling of post-combustion carbon capture in power plants and process industries - partial capture and load following conditions

   Författare :Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; MEA; ammonia; dynamic modelling; chemical absorption; industrial sources;

   Sammanfattning : Carbon capture and storage (CCS) is recognized as a potent technology for the mitigation of global warming, since it can significantly reduce CO2 emission from large point source emitters. Post-combustion CO2 capture using chemical absorption is a versatile end-of-pipe technology that can be implemented at all point sources of CO2, such as a power production facility or industrial plant.

3. 12. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

   Författare :Rosa Aragao; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

   Sammanfattning : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. LÄS MER

4. 13. When bioelectrochemical systems meet extremophiles, possibilities and challenges

   Författare :Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

   Sammanfattning : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. LÄS MER

5. 14. Sampling and analysis of polynuclear aromatic hydrocarbons with special reference to automobile exhausts

   Författare :Ulf Stenberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : A literature survey concerning the progress in sampling of polynu clear aromatic hydrocarbons, PAH, from automobile exhausts is pre seated. In this conjunction the included analytical methods are discussed, and some emphasis is put on injection technique and column performance. LÄS MER

7. 15. Used but not Sensed - The Paradox of D-xylose Metabolism in Saccharomyces cerevisiae

   Författare :Karen Ofuji Osiro; Teknisk mikrobiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; saccharomyces cerevisiae; sugar sensing signalling; D-Xylose; XR XDH; GFP biosensor; cAMP PKA; Snf3p Rgt2p; SNF1 Mig1p; flow cytometry;

   Sammanfattning : The realization that the extraction and combustion of fossil fuels is having serious effects on the environment and the climate, together with the ever-growing need for fuels, has led to the development of the concept of the biorefinery. Biorefineries are refineries in which fossil resources, such as oil, are replaced by renewable biomaterials to produce biofuels and biochemicals. LÄS MER
