1. 1. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

   Författare :Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Sammanfattning : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. LÄS MER

3. 2. System studies of MCFC power plants

   Författare :Benny Fillman; Pehr Björnbom; Professor Mats Westermark; Gábor Merényi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cells; fuel cell systems; system studies; process simulation; molten carbonate; Brennstoffzellen; Brennstoffzellensystem; Systemanalyse; Prozeßsimulation; Bränsleceller; bränslecellssystem; systemstudier; processimulering; smältkarbonatbränslecell; Chemical engineering; Kemiteknik;

   Sammanfattning : Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. LÄS MER

4. 3. Molten carbonate fuel cells for electrolysis

   Författare :Lan Hu; Carina Lagergren; Göran Lindbergh; Søren Højgaard Jensen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Durability; electrode kinetics; gas phase mass transport; molten carbonate electrolysis cell; molten carbonate fuel cell; performance; reversible.; Chemical Engineering; Kemiteknik;

   Sammanfattning : The molten carbonate fuel cell has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis, it provides a promising option for producing fuel gases such as hydrogen and syngas. The cell can thereby operate reversibly as a dual energy converter for electricity generation and fuel gas production. LÄS MER

5. 4. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

   Författare :Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER
