Published in 2019 at "Ceramics International"

DOI: 10.1016/j.ceramint.2019.05.180

Abstract: Abstract Despite huge potential, Al2O3–CaO–Cr2O3 system has been one of the least investigated one due to the generation of carcinogenic and toxic Cr(VI) compounds. Herein, we investigated the system under air atmosphere varying Cr2O3 while… read more here.

Published in 2017 at "Journal of Rare Earths"

DOI: 10.1016/j.jre.2017.06.001

Abstract: Abstract The thermal decomposition of CeCl3·7H2O was studied from room temperature to 800 °C. Analysis was performed by applying TG–DTA, XRD, FESEM, EDXS, and TG–MS technologies to investigate the thermal decomposition mechanism of CeCl3·7H2O in air… read more here.

Published in 2020 at "Tetrahedron Letters"

DOI: 10.1016/j.tetlet.2020.152124

Abstract: Abstract A new structure of saturated ring skeleton monoligated NHC-Pd-Imine complex was easily synthesized and unambiguously confirmed by X-ray single crystal diffraction. It was found to be an efficient and air-stable catalyst for the α-arylation… read more here.
