1. Biodegradable Thermoplastic Elastomers
Abstract : A novel strategy for synthesising segmented poly(urethane urea) (PUU) without using a chain extender but nevertheless with the opportunity to vary the hard segment content has been developed. The strategy is based on amine formation from isocyanate upon reaction with water. READ MORE

2. Synthesis, Characterisation and Properties of Biomimetic Biodegradable Polymers
Abstract : The acceptance of blood contacting implants creating favorable conditions in vivo is decisively determined by their interaction with proteins that mediate inter cellular interactions with synthetic substrates. Adsorbed proteins can activate blood cascade systems like coagulation and complement that may result in serious blood clots, and/or immunological reactions. READ MORE

3. Biodegradable magnesium implants, immunomodulation, and tissue repair/regeneration
Abstract : The century-old paradigm of holding fractures with a metallic implant to enable bone repair, known as osteosynthesis, is still used today without alteration. Patients are increasingly being treated with metallic implants made of magnesium (Mg) that secure osteosynthesis and are reabsorbed in situ without the surgical re-entry that requires their permanent analogs.

4. Spark plasma sintered ZrO2-SiO2 glass ceramics and Si3N4 bioceramics
Abstract : This thesis focuses on elaboration and characterization of two types of bioceramics: one is ZrO2-SiO2 nanocrystalline glass ceramic (NCGC) for dental application. The goal is to develop new ZrO2-SiO2 NCGCs with a combination of high strength and high translucency; the other is biodegradable Si3N4 ceramics for spinal fusion. READ MORE

5. Development of a New Oral Vaccine against Diphtheria and the Study of its Immunogenicity in Mouse and Man
Abstract : Most pathogens enter the body via mucosal surfaces. In contrast to parenterally administered vaccination, mucosal vaccination has the advantage of eliciting both a systemic and a local mucosal immune response. An oral biodegradable adjuvant with these features would have great potential. READ MORE
