Bone implants with multi layers coatings and their processing methood

In the frame of Meddelcoat project (FP7, IP-SME) and doctoral study of Nataša Drnovšek, we developed a new multilayer coating for bone implants and the process for production thereof. The tests confirmed that the bioactive glass-coating significantly enhance osseointegration, i.e. bone ingrowth into the porous surface layer on titanium implants. The coating and the process have been patented in Slovenija, and recently, European and USA patent applications have been filed.

Controlled synthesis of TiO2, nanoparticles and their application in photovoltaics

For the synthesis of nano-sized TiO2 powders we have successfully tailored the sol-gel, gel-sol and hydrothermal synthesis processes so that we are able to produce TiO2 nanopowders with anatase and/or rutile structure with desired nano-crystal sizes, size distribution and morphology. By the sol-gel procedure it was only possible to synthesize TiO2 nanoparticles with the rutile structure while the sol-gel procedure enabled the synthesis of TiO2 nanoparticles with both, the anatase and the rutile structure. Depending on the processing parameters it was possible to control the final size of polycrystalline TiO2 nanoparticles. Thus the rutile nanoparticles ranged from 60 to 160 nm in size, while the anatase nanoparticles ranged from 40 to 60 nm. The hydrothermal synthesis yielded spherical monocrystal TiO2 nanoparticles with the anatase structure with the average size of 30 nm. Polycrystalline TiO2 nanoparticles with the anatase structure were successfully used for protective coatings which exhibited photocatalytic activity and also superhydrophility.

R & D breakthrough in the field of ZnO-based varistor ceramics

In the field of ZnO-based varistor ceramics we studied the influence of Bi4Ti3O12 addition on grain growth and microstructure development. The results are important for development of varistor ceramics with very low breakdown voltages below 50V/mm. The development of thick-film varistors was focused on studying the influence of organic vehicle and the amount of added varistor powder filler on the rheological characteristics of pastes and their screen printing performance.

Replacement and Original Magnet Engineering Options

In 2012 we successfully won the EU FP7 project “Replacement and Original Magnet Engineering Options« (ROMEO) in which we are the coordinator (S. Kobe) and active research group in grain boundary engineering (GBE) and characterization of magnets by using magnetic properties measurements and high resolution electron microscopy on nano and atomic level. The final goals of the project are two: decreasing and/or completely avoiding the use of heavy rare-earth in Nd-Fe-B high energy magnets and secondly invent new magnets, which will have properties between ferrites and high energy magnets based on rare-earth and transition metals. The consortium involves all European main laboratories (Austria, France, Ireland, Germany, Slovenia) and industrial partners (Vacuumschmelze, Siemens, Daimler, Valeo and Kolektor Group. The value of the project is ~ 4 mio EUR
