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 ...
MgAl2O4:Cr3+ luminescence thermometry probe in the physiological temperatures range
(Ceramics International, 2021)
Temperature sensing from the photoluminescence of MgAl2O4:Cr3+ ceramic powder is systematically investigated. Material was prepared by self-propagating high temperature synthesis method. In this host, Cr3+ experiences the ...
Electrochemical and structural study on cycling performance of γ-LiV2O5 cathode
(Ceramics International, 2021)

(Ceramics International, 2021)
Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies ...
Structure, electrochemical impedance and Raman spectroscopy of lithium-niobium-titanium-oxide ceramics for LTCC technology
(Ceramics International, 2021)
Resultsof Electrochemical Impedance Spectroscopy (EIS) are reported for lithium-niobium-titanium-oxide (LNTO) ceramics synthesized by a solid-state reaction method with two functional additives (MoO3 or ZnO) in the temperature ...
Sensitive temperature reading from intensity ratio of Cr3+ and defects’ emissions in MgTiO3:Cr3+
(Ceramics International, 2021)
The luminescence thermometry based on the intensity ratio of Cr3+ and host emissions in the Cr3+ activated MgTiO3 phosphor powder is demonstrated over the 100–350 K temperature range. Phosphor was prepared by a two-step ...
