In the final year of the Meddelcoat project (FP6, IP-SME), we were mainly engaged in evaluation of the success of developed bioactive coatings on metal implants with porous surface. After in vivo tests two of the coatings prepared at JSI, anatase and bioactive glass, revealed significant enhancement of osseointegration in comparison with the samples without coating or with differently prepared coatings.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 23782183We continued the study of synthesis of titania particles in anatase and rutile crystal form using sol-gel and hydrothermal methods. The influence of process parameters on the size, morphology and photocatalytic efficiency of particles was studied. The nucleation and growth of anatase particles to the specific bi-pyramid morphologies was explained. Due to the difference in the energies of certain crystal planes and non-equilibrium conditions the growth of starting block-like particles continue through asymmetric rod-like particles elongated in one of the (101) directions. The particles morphologies were reconstructed from HRTEM images.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 23426087In collaboration with VARSI company two projects were successfully completed. The development of surge protections for the solar panels and wind turbine generators required improvement of the dc stability of the ZnO-based varistors. Within the project Novel innovative systems for electrical equipment complex shaped tubular or oval hollow varistors were developed using slip-casting technology.
