Dielectric and piezoelectric properties of barium calcium zirconate titanate ceramics
Johnsen, Elin Hagen (Master thesis, 2019)Det ferroelektriske systemet barium calcium zirconate titanate er av høy interesse for bruk i industrielle applikasjoner på grunn av eksepsjonelt høye piezoelektriske koeffisienter. Videre så utgjør det et interessant ... -
Freeze casting of piezoelectric BCZT for biomedical applications
Andersen, Freya Sofia (Master thesis, 2019)Bruken av piezoelektriske keramer som beinimplantat gir muligheten til å forsterke heling av skadet bein gjennom elektrisk stimulering in vivo. På denne måten kan rekonvalesenstiden og sannsynligheten for revisjonsutskiftninger ... -
Influence of processing on stability, microstructure and thermoelectric properties of Ca3Co4-xO9+δ
Kanas, Nikola; Singh, Sathya Prakash; Rotan, Magnus; saleemi, Mohsin; Bittner, Michael; Feldhoff, Armin; Norby, Truls Eivind; Wiik, Kjell; Grande, Tor (Journal article; Peer reviewed, 2018)Due to high figure of merit, Ca3Co4-xO9+δ (CCO) has potential as p-type material for high-temperature thermoelectrics. Here, the influence of processing including solid state sintering, spark plasma sintering and ... -
Phase composition, microstructure and resistance to attrition of alumina-based supports for Fischer-Tropsch catalysts
Rotan, Magnus (Doktoravhandlinger ved NTNU, 1503-8181; 2012:43, Doctoral thesis, 2012)The key element in gas-to-liquid technology is the Fischer-Tropsch (FT) synthesis in which liquid hydrocarbons are produced from syngas (CO and H2). During FT synthesis the catalyst and the catalyst support are subjected ... -
Thermoelectric Properties of Ca3Co2−xMnxO6 (x = 0.05, 0.2, 0.5, 0.75, and 1)
Kanas, Nikola; Singh, Sathya Prakash; Rotan, Magnus; Desissa, Temesgen Debelo; Grande, Tor; Wiik, Kjell; Norby, Truls Eivind; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2019)High-temperature instability of the Ca3Co4−yO9+δ and CaMnO3−δ direct p-n junction causing the formation of Ca3Co2−xMnxO6 has motivated the investigation of the thermoelectric performance of this intermediate phase. Here, ...
