  • Doping of alumina ceramics by manganese – Thermodynamical and experimental approach 

    Svoboda, Jiří; Drdlíková, Katarina; Drdlík, Daniel; Kroupa, Aleš; Michalička, Jan; Maca, Karel (Faculty of Technology, University of Novi Sad, 2022-03-27)
    The preparation of a transparent ultra-fine-grained doped ceramics requires a homogeneous dopant distribution in a matrix. In the present work, two thermodynamical phenomena allowing the preparation of such ceramics (the ...
  • Macroporous bioceramic scaffolds based on tricalcium phosphates reinforced with silica: microstructural, mechanical, and biological evaluation

    The positive effect of silica on microstructural, mechanical and biological properties of calcium phosphate scaffolds was investigated in this study. Scaffolds containing 3D interconnected spherical macropores with diameters ...
  • Comprehensive characterization of PVDF nanofibers at macro- and nanolevel 

    Pisarenko, Tatiana; Papež, Nikola; Sobola, Dinara; Ţălu, Ştefan; Částková, Klára; Škarvada, Pavel; Macků, Robert; Ščasnovič, Erik; Kaštyl, Jaroslav (MDPI, 2022-02-01)
    This study is focused on the characterization and investigation of polyvinylidene fluoride (PVDF) nanofibers from the point of view of macro- and nanometer level. The fibers were produced using electrostatic spinning process ...
  • Luminescent Eu3+-doped transparent alumina ceramics with high hardness 

    Drdlíková, Katarina; Klement, Róbert; Hadraba, Hynek; Drdlík, Daniel; Galusek, Dušan; Maca, Karel (Elsevier, 2017-05-17)
    The Eu3+-doped transparent aluminas were prepared by wet shaping technique followed by pressureless sintering and hot isostatic pressing. The effect of dopant amount on microstructure, real in-line transmission (RIT), ...
  • Processing and properties of luminescent Cr3+ doped transparent alumina ceramics 

    Drdlíková, Katarina; Klement, Róbert; Drdlík, Daniel; Galusek, Dušan; Maca, Karel (Elsevier, 2020-07-01)
    Transparent Cr2O3-doped alumina ceramics were prepared by slip casting, followed by pre-sintering in ambient atmosphere and hot isostatic pressing. The effect of dopant concentration on material properties, including ...
  • Thermal annealing effects in polycrystalline EuTiO3 and Eu2Ti2O7 

    Schell, Juliana; Kamba, Stanislav; Kachlík, Martin; Maca, Karel; Drahokoupil, Jan; Rano, B. Rahman; Gonçalves, Joo Nuno Santos; Dang, Thien Thanh; Costa, Angelo; Noll, Cornelia; Vianden, Reiner; Lupascu, Doru C. (AIP Publishing, 2019-12-01)
    Using time-differential perturbed angular correlation of gamma rays, we investigated the electric-field gradient of polycrystalline EuTiO3 and Eu2Ti2O7, with Hf-181(Ta-181) as a probe, following different thermal treatments. ...
  • Transparent alumina ceramics: Effect of standard and plasma generated stabilizing approaches in colloidal processing 

    Drdlíková, Katarina; Maca, Karel; Sláma, Martin; Drdlík, Daniel (Wiley, 2019-10-04)
    The study is focused on an optimization of the slipcasting process used for the fabrication of the transparent/translucent alumina ceramics; more precisely, on specifying the most appropriate way to stabilize the cast ...
  • Microstructure and Phase Composition Of Steatite Ceramics Sintered by Traditional and Spark Plasma Sintering 

    Terzić, Anja; Obradović, Nina; Pouchlý, Václav; Stojanović, Jovica; Maca, Karel; Pavlović, Vladimir B. (International Institute for the Science of Sintering, Beograd, 2018-03-01)
    The influence of the sintering method on the mineral phase transformations and development of the crystalline microstructure of steatite ceramics was investigated. The steatite samples were fabricated from talc and bentonite ...
