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

    Author : Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Amorphous magnesium carbonate nanomaterials : Synthesis, characterization and applications

    Author : Jiaojiao Yang; Ken Welch; Mika Lindén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high surface-to-volume ratio; nanoparticles; mesoporous; magnesium carbonate; amorphous drugs; supersaturated concentration; general adhesives; UV-shielding;

    Abstract : High surface-to-volume ratio materials, including nanoparticles and mesoporous materials, have a number of applications due to their large surface area and special structures. Traditional approaches for synthesizing high surface-to-volume ratio nanomaterials are often complicated, expensive or environmentally unfriendly. READ MORE

  5. 3. Mesoporous magnesium carbonate as a drug delivery vehicle for stabilising amorphous drugs and regulating their release rate

    Author : Peng Zhang; Maria Strømme; Niklas Hedin; Uppsala universitet; []
    Keywords : mesoporous; magnesium carbonate; drug delivery; solubility enhancement; bioavailability; pharmacokinetics; diffusion release; controlled release; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Abstract : In today’s drug discovery, the number of candidate drugs based on new molecular entities with poor aqueous solubility is increasing. Since poor aqueous solubility of an active pharmaceutical ingredients (APIs) is associated with low bioavailability and thus limite their therapeutic effect, this is often a great challenge in the development of new drugs when oral administration is the preferred route of administration.

  6. 4. New Materials for the Molten Carbonate Fuel Cell

    Author : Sara Randström; Carina Lagergren; Michel Cassir; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molten Carbonate Fuel Cell; Anode current collector; Cathode; Wet-seal; Ionic liquid; TFSI; Smältkarbonatbränslecell; Anodströmtilledare; Katod; Wet-seal; Jonvätska; TFSI; Electrochemistry; Elektrokemi;

    Abstract : Smältkarbonatbränslecellen (MCFC) är en högtemperaturbränslecell för stationära applikationer. Den har samma höga totalverkningsgrad som konventionella kraftvärme-anläggningar, men kan byggas i mindre moduler (från 250 kWe). READ MORE

  7. 5. The Atmospheric Corrosion of Magnesium Alloys : Influence of Microstructure and Environments

    Author : Martin Jönsson; Christofer Leygraf; Rajan Ambat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; metallurgy; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik;

    Abstract : The low density and high specific strength of magnesium alloys have created a great deal of interest in the use of these alloys in the automotive and aerospace industries and in portable electronics. All of these industries deal with applications in which weight is extremely important. READ MORE
