Luminescence temperature sensing using thin-films of undoped Gd2O3 and doped with Ho3+, Eu3+ and Er3+ prepared by plasma electrolytic oxidation
(Ceramics International, 2020)
The steady-state luminescence thermometry analysis was performed on thin-films of undoped Gd2O3 and Gd2O3 doped with Ho3+, Eu3+ and Er3+, created by the plasma electrolytic oxidation process. The experimental setup for ...
Magnetic properties of mesoporous hematite/alumina nanocomposite and evaluation for biomedical applications
(Ceramics International, 2021)
A porous hematite/alumina nanocomposite is produced by sol-gel combustion synthesis. The XRPD, Raman and FTIR methods show the presence of α-Fe2O3 phase while SEM, TEM, EDS and BET techniques further reveal the formation ...
Novel cordierite-acicular mullite composite for diesel particulate filters
(Ceramics International, 2021)
Cordierite-acicular mullite composites containing 0, 25, 50, 75 and 100 wt% of mullite were fabricated from waste MoSi2 and commercial powders of Al2O3 and spinel (MgAl2O4). Careful oxidation of pulverised waste MoSi2 ...
Structural and morphological characterization of iron-doped sol-gel derived mullite powders
(Ceramics International, 2020)
The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3–15 wt% Fe2O3 were synthesized by ...
