Journal ArticleDOI
The size-effect on luminescence properties of BaTiO3:Eu3+ nanocrystallites prepared by the sol-gel method
Dariusz Hreniak,Wieslaw Strek,J. Amami,Yannick Guyot,Georges Boulon,Christelle Goutaudier,Robert Pazik +6 more
TL;DR: In this article, the effect of nanocrystalline (nc) BaTiO3 powders doped with Eu3+-ions prepared by the sol-gel method is described.
Journal ArticleDOI
Luminescence properties of Tb3+:Y3Al5O12 nanocrystallites prepared by the sol–gel method
TL;DR: In this paper, the average grain sizes of Tb 3+ :Y 3 Al 5 O 12 powders have been determined by X-ray powder diffraction measurements and the concentration dependence of the luminescence spectra and lifetimes have been investigated as a function of the YAG grains sizes.
Journal ArticleDOI
Precursor and solvent effects in the nonhydrolytic synthesis of complex oxide nanoparticles for bioimaging applications by the ether elimination (Bradley) reaction.
Robert Pazik,Renata Tekoriute,Sebastian Håkansson,R. J. Wiglusz,Wieslaw Strek,Gulaim A. Seisenbaeva,Yurii K. Gun'ko,Vadim G. Kessler +7 more
TL;DR: Investigation of the solvent and alkoxide precursor effect on the nonhydrolytic sol-gel synthesis of oxide nanoparticles by means of an ether elimination (Bradley) reaction indicates that the best crystallinity of the resulting oxide particles is achieved on application of aprotic ketone solvents and of smallest possible alkoxide groups.
Journal ArticleDOI
AMPK-mediated senolytic and senostatic activity of quercetin surface functionalized Fe3O4 nanoparticles during oxidant-induced senescence in human fibroblasts.
Anna Lewinska,Jagoda Adamczyk-Grochala,Dominika Bloniarz,Jakub Olszowka,Magdalena Kulpa-Greszta,Grzegorz Litwinienko,Anna Tomaszewska,Maciej Wnuk,Robert Pazik +8 more
TL;DR: Quercetin surface functionalized Fe3O4 nanoparticles (MNPQ) may be considered as promising candidates for senolytic- and senostatic-based anti-aging therapies for the first time.
Journal ArticleDOI
Heteroleptic metal alkoxide "oxoclusters" as molecular models for the sol-gel synthesis of perovskite nanoparticles for bio-imaging applications.
TL;DR: Systematic structural study of the molecules, resulting from microhydrolysis of heterometallic beta-diketonate alkoxides of barium and strontium (single-source precursors of perovskite oxide materials), demonstrates that the structures of these products result from a thermodynamically driven self-assembly of metal cations and ligands directed towards the most densely packed cores.
