Mission - controlling the interaction of surfaces and interfaces ubiquitous in powder technology. Interfacial interactions are investigated at an atomistic level using classical energy minimisation and molecular dynamic simulations as well as thermodynamic speciation in solution. The interactions between particles in suspension is a strong theme –in de-agglomeration of nanosized powders, the rheological behaviour of cementitious materials or self-assembly during precipitation. Using inorganic or organic additives, the interfacial properties and interactions between particles and development of microstructures can be modified and controlled. This has lead to controlled morphology and self-assembly of nanostructured calcite and various oxalates; more efficient dispersion of cement; the production of transparent polycrystalline alumina; and novel nanoparticles and porous nanostructured particles for photocatalytic antibacterial and ion beam production applications.
He has been active in the international community, chairing over 20 sessions at international conferences, on the international advisory board for 16 conferences, has given 30 invited lectures at international conferences and is on the advisory board of two scientific journals.
Dr. Bowen was elected as a Fellow of the European Ceramic Society in June 2013 - for contributions to ceramic science - the first Swiss scientist to recieve this honour.
