  1. 1. Harnessing Mesoporous Spheres - transport studies and biotechnological applications

    Författare :Jovice Boon Sing Ng; Lennart Bergström; Frank Caruso; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesoporous; spheres; particles; CLSM; TEM; controlled-release; molecular transport; lipid membrane; enzyme; intraparticle; lipase; solid support; Inorganic chemistry; Oorganisk kemi; materialvetenskap; Materials Science;

    Sammanfattning : Applications in controlled release and delivery calls for a good understanding of molecular transport within the carrier material and the dominating release mechanisms. It is clear that a better understanding of hindered transport and diffusion of guest molecules is important when developing new porous materials, e.g. LÄS MER

  3. 2. Studies of Charge Transport Processes in Dye-sensitized Solar Cells

    Författare :Kristofer Fredin; Anders Hagfeldt; Mukundan Thelakkat; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solar cell; mesoporous; dye-sensitized; model; simulation; electron transport; trap distribution; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Dye-sensitized solar cells (DSCs) have attained considerable attention during the last decade because of the potential of becoming a low cost alternative to silicon based solar cells. Although efficiencies exceeding 10% in full sunlight have been presented, major improvements of the system are however limited. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Advanced Methods for Evaluation of the Performance of Complex Drug Delivery System

    Författare :Caroline Alvebratt; Christel Anna Sofia Bergström; Maria Strömme; Caitriona O'Driscoll; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amorphous solid dispersion; coadministration; digestion; dissolution; drug absorption; enabling formulation; in vitro assay; lipid-based formulation; mesoporous carrier; supersaturation; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Low oral bioavailability of drugs originating from poor aqueous solubility is a common issue in drug development. Various enabling formulations have been presented to circumvent this limitation, many making use of supersaturation. In these, the drug is delivered to the gastro-intestinal lumen in a high energy state e.g. LÄS MER

  7. 5. Mesoporous material systems for catalysis and drug delivery

    Författare :Aylin Atakan; Magnus Odén; Cristina Canal; Petra de Jongh; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Hybrid material systems possess multi-functional properties which make them intriguing for the materials science community since very early dates. However, it is not straightforward to produce such material systems. A smart and efficient approach is necessary to extract the desired properties of each component under the desired conditions.
