1. 6. Graphite oxides for preparation of graphene related materials : structure, chemical modification and hydrogen storage properties

   Författare :Alexey Klechikov; Alexandr Talyzin; Tamás Szabó; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphite oxide; graphene oxide; hydrogen storage; nanomaterials; adsorption; surface area; pore volume; Materials Science; materialvetenskap;

   Sammanfattning : Carbon materials have been studied for hydrogen storage for decades, but they showed too low capacity at ambient temperature compared to target values for practical applications. This thesis includes two parts. First one is fundamental study of graphite oxides (GO) structure and properties. LÄS MER

3. 7. Electrochemical reduction of protons and organic molecules in hydrogen technologies : Liquid Organic Hydrogen carrier and Hydrogen Evolution

   Författare :Hamid Ghorbani Shiraz; Magnus Berggren; Xavier Crispin; Ola Wendt; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Storage; LOHC; Hydrogen Evolution; Electrocatalyst;

   Sammanfattning : In accordance with preventable actions to mitigate the effect of climate change in the modern societal applications, renewable energy is an unavoidable and decisive factor in the energy industry. The energy sources that offer non-depleted and environment-friendly pathways for the energy sector are in focus. LÄS MER

4. 8. Non-geological hydrogen storage for fossil-free steelmaking

   Författare :Joakim Andersson; Stefan Grönkvist; Simon Harvey; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen storage; fossil-free; steelmaking; industrial decarbonization; hydrogen direct reduction; Chemical Engineering; Kemiteknik;

   Sammanfattning : In the last half-century, global steel use has increased more than threefold and further growth is expected, particularly in developing economies. However, steelmaking is currently responsible for 7% of the global net carbon dioxide (CO2) emissions, and any substantial further optimization of existing processes that utilize fossil fuels for iron ore reduction is infeasible.

5. 9. Quality of Frozen Rainbow Trout. Effects of different freezing and thawing treatments

   Författare :Katarina Nilsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane disintegration; liquid loss; centrifuged tissue fluid; fish; lysosomal enzyme; frozen storage; glazing; freezing; sensory quality; rainbow trout; thawing;

   Sammanfattning : The effects of different freezing, frozen storage and thawing treatments on the muscle tissue of farmed rainbow trout (Oncorhychus mykiss) were studied. Biochemical measurements were correlated to sensory estimated quality changes. The freezing process affects the proteins, the lipid fractions and the membrane structures in the fish muscle. LÄS MER

7. 10. Digital Electrical DNA Sensing

   Författare :Maoxiang Guo; Wouter van der Wijngaart; Fredrik Westerlund; KTH; []
   Nyckelord :DNA detection; thiol-ene-epoxy; rolling circle amplification; digital measurement; DNA stretching; microwell-array; gold nanowires; electrical measurement; specificity; limit of detection; liquid storage; disease diagnosis; lab-on-a-chip; point-of-care.;

   Sammanfattning : Molecule detection is a workhorse in life sciences and medicine, for example in cancer diagnosis and virus and bacterial detection. DNA analysis can provide vital information about the state of a host organism and its medical and health condition. LÄS MER
