Casimir-Lifshitz Force Based Optical Resonators
(American Chemical Society, 2019)
We theoretically investigate the building of optical resonators based on the levitation properties of thin films subjected to strong repulsive Casimir-Lifshitz forces when immersed in an adequate medium and confronted with ...

Toughening of complete solid solution cermets by graphite addition
(Elsevier, 2015)
(Ti0.95Ta0.05)(C0.5N0.5)-Co complete solid solution cermets (CSCs) were developed by a mechanochemical synthesis process and a pressureless sintering method. The effect of different percentages of graphite used as a sintering ...

Synergy between gold and oxygen vacancies in gold supported on Zr-doped ceria catalysts for the CO oxidation
(Elsevier, 2015)
The CO oxidation activity of 1 wt.% gold catalysts prepared by depositionprecipitation on a series of ceria doped with Zr supports was studied. The supports (10, 25 and 50 Zr At. %) were synthesized by a pseudo sol-gel ...

Anisotropic lattice expansion determined during flash sintering of BiFeO3 by in-situ energy-dispersive X-ray diffraction
(Elsevier, 2019)
BiFeO3 has a Curie temperature (TC) of 825 °C, making it difficult to sinter using conventional methods while maintaining the purity of the material, as unavoidably secondary phases appear at temperatures above Tc. Flash ...
