Project Description
Main Objective:
- To achieve excellent bactericidal properties by chemical and topological design of precious metal-based glasses for dental applications
Tasks:
- Fabrication of precious metal bulk amorphous alloys containing Cu and/or Ag by casting and optional by additive manufacturing
- Topological modifications by thermoplastic surface patterning
- Study an oxidation approach to increase the Cu / Ag surface concentration
- Evaluation of degradation / corrosion kinetics in simulated body fluids (metal ion release and electrochemical measurements)
- Feasibility / scale-up study for the manufacturing of small dental parts.
Expected Results:
- Quantitative relationship between bactericidal properties and design aspects
- "Best-practice" guidelines for optimized processing
- Understanding the design – processing – property relationship for a roadmap scheme of the production of dental parts at semi-industrial scale.
The ESR will travel abroad for research secondments at different institutions within the BIOREMIA Network (e.g. at Montanuniversität Leoben-Austria, Goeteborgs Universitet-Sweden, Yale University-US) and will participate in specialised training meetings and international conferences.
The ESR will enroll in the doctoral program at Montanuniversität Leoben- Austria.
