Cellular response to calcium phosphate cements

Cecen, Berivan; Kalemtaş, Ayşe; Topates, Gulsum; Kozaci, Leyla Didem (Elsevier, 2020)

Calcium orthophosphate (COP) ceramics have been investigated as bone repair materials for many decades. The first in vivo application of these materials was accomplished in 1920 to test tricalcium phosphate performance as ...
Production of Si3N4 porous beads via carbothermal reduction and nitridation technique

Topates, Gulsum; Kalemtaş, Ayşe (Taylor & Francis Ltd, 2020)

Si(3)N(4)porous beads were produced from direct carbothermal reduction and nitridation of spheres composed of carbon+SiO(2)mixtures. A simple one-step sol-gel templating technique was used to prepare carbon+SiO2(molar ratio ...
Starch consolidation of SiC ceramics: processing and low-temperature sintering in an air atmosphere

Kalemtaş, Ayşe; Topates, Gulsum; Aydin, M. Turkay Aytekin; Ozey, Nigar (Taylor & Francis Ltd, 2020)

Highly porous SiC ceramics containing borax decahydrate were produced by a starch consolidation method in which corn starch was used as a shaping and pore-forming additive. Four different compositions were prepared with ...
