    Sammanfattning : Consumers put higher demands on low environmental impact from the products they use, and the materials they consist of. As a result, more research is being made on finding environmentally friendly production techniques and materials. Hydrothermal carbonization (HTC) is a relatively environmentally friendly method that has been used in this study. LÄS MER

    Sammanfattning : The cement and concrete industry stand for approximately 8% of the global CO2 emissions. The demand of concrete and cement is expected to increase rapidly with the growing world population and increased urbanization. This makes it of the utmost importance for the industry to try to mitigate its emissions. LÄS MER

  7. 5. Using Upsalite® as drug delivery vehicle : Increasing the solubility of poorly soluble drugs by stabilizing their amorphous state

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaci

    Författare :Ottilia Arvén; [2017]
    Nyckelord :;

    Sammanfattning : Poor aqueous solubility is an issue not only in drug discovery and development but also for registered drug products, since poor drug solubility is often related to poor absorption (bioavailability). There are several methods available to increase the aqueous solubility and dissolution rate of pharmaceutical formulations. LÄS MER
