The patent relates to a simple noninvasive process for enhancing the adhesion of dental cements to ceramic dentures that exploits the hydrolysys of AlN powder in a water suspension. The process was developed within the PhD thesis of A. Kocjan, while the implementation was part of a PhD thesis of P. Jevnikar and master thesis of M. Golobic, whose presentations were recognized by the Pfaffenberg award given by ADM to outstanding students achievemnets in 2010 and ECERS in 2012 for the best student's poster.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 21150759In collaboration with Ustna Medicina d.o.o. next generation bioactive sealer for endodontic treatment of teeth, described in technical innovation. They improved bioactive, rheological (handling) and chemical properties of the sealer that is based on mineral trioxide aggregate (MTA) and that has been in use for over 20 years but has according to clinicians still many deficiencies. Close collaboration between the dental clinic (company) and scientists conducting the translational medicine and, thus implementing knowledge from both, materials science and dental medicine, that resulted in improved technology and more efficient implementation. Better flowability, bioactivity and shorter setting time together with radio-opacity were achieved by studying the influence of particle size, composition, and by the addition of submicron sized bioactive component, clay-like material and zirconia radio-opaque filler. We are now in the final stages of establishing a spin-out company, Genuine Technologies, that will be based on the licensed knowledge from Jožef Stefan Institute. Technology that provides more successful treatment Will be therefore opened for pacients.
F.19 Knowledge that leads to a company spin off
COBISS.SI-ID: 30665255In collaboration with Materials Science Institute of Madrid we have developed cellulose nanofiber-reinforced engineering electro-conductive ceramics and filed Great Britain patent application. Imparting electrical conductivity to a dielectric ceramic like alumina or zirconia with conducting nanocarbons (nanotubes or graphene) is challenging due to colloidal instability, particle segregation resulting in inhomogeneities. Instead, we used small addition of cellulose nanofibers, which render highly homogeneous ceramic dispersions due to the increased hydrophilicity character. Nanofibers not only significantly reinforce the ceramic green body, but upon sintering also converts to finely distributed graphitic excellulose carbon nanofibers within dense and refined ceramic matrix resulting in highly electro-conducting alumina and zirconia ceramics.
F.32 International patent
COBISS.SI-ID: 29926439The interview was triggered by the TEDx talk of interviewee. In her TEDx talk interviewee pointed out the issues of gender equality in science and that was the starting point for the interview, which was continued by the discussion about her work in the field of nanosciences and nanotechnologies. We talked also about what “nano” means and how do we exploit advantages of nanomaterials in general and in the field of ferrite magnets. In the end we also talked about fusion as a possible source of energy in the future.
F.30 Professional assessment of the situation
COBISS.SI-ID: 29625127The prospects of nanoceramics of the future are discussed. What nano means and how are nanoceramics prepared, shaped and sintered, especially by employing the modern sintering techniqes, such as SPS; and how this extrapolates to their applicability, for example, porous materials used for insulation, biomaterials of the future and transparent ceramics. The interview was published in a public journal with the biggest daily printout.
