    Sammanfattning : Microfluidic devices have long been considered an ideal tool for rapid and inexpensive chemical analysis and reactions in areas ranging from point-of-care health to national security applications. However, fabricating microfluidic devices is time consuming, difficult and above all expensive. LÄS MER

  3. 2. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins

    Sammanfattning : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).
