Sammanfattning : Cemented carbides are known to be very wear resistant and are therefore often usedin applications involving surface damage and wear. The work presented hereinvestigates the coupling between the microstructure and some fundamental wearand deformation mechanisms typical for cemented carbides. LÄS MER
Sammanfattning : Dentin hypersensitivity is one of the most prevalent conditions related to oral health, affecting a large share of the adult population. Shortcomings with the available treatment options are related to non-ideal particle sizes and degradation properties. LÄS MER
Sammanfattning : This thesis aimed to investigate and document the potential of applying ceramics in two specific drug delivery applications: tamper-resistant opioid formulations and transdermal enhancement protrusions.Geopolymers were developed into the matrix for a tamper-resistant formulation, aiming to protect drug substances from non-medical abuse. LÄS MER
Sammanfattning : Opioid therapy for chronic pain generally use controlled release formulations to deliver analgesic drugs around-the-clock. Controlled release dosage forms can enlarge the therapeutic effect by controlling the rate and site of release. However, with high drug content, opioid formulations are easily targeted for non-medical use. LÄS MER
Sammanfattning : Despite extensive preventative efforts, the problem of controlling infections associated with biomedical materials persists. Bacteria tend to colonize on biocompatible materials and form biofilms; thus, novel biomaterials with antibacterial properties are of great interest. LÄS MER
