Journal ArticleDOI
WO3 photocatalysts: Influence of structure and composition
Imre Miklós Szilágyi,Imre Miklós Szilágyi,Balázs Fórizs,Olivier Rosseler,Ágnes Szegedi,Péter Németh,Péter Király,Gábor Tárkányi,Balázs Vajna,Katalin Varga-Josepovits,Krisztina László,Attila Tóth,Péter Baranyai,Markku Leskelä +13 more
TL;DR: In this paper, the formation, structure, composition, morphology, and optical properties of hexagonal and monoclinic WO3 nanoparticles were analyzed by powder X-ray diffraction, scanning and transmission electron microscopy combined with electron diffraction.
Journal ArticleDOI
Spherical mesoporous MCM-41 materials containing transition metals: Synthesis and characterization
Ágnes Szegedi,Zoltán Kónya,Dóra Méhn,Edit Solymár,Gabriella Pál-Borbély,Zsolt Endre Horváth,László P. Biró,Imre Kiricsi +7 more
TL;DR: In this article, transition metal containing spherical MCM-41 silicates were prepared and characterized by transmission electron microscopy (TEM), XRD, BET, TPR and IR spectroscopy.
Journal ArticleDOI
Carboxylic modified spherical mesoporous silicas аs drug delivery carriers.
Margarita Popova,Ágnes Szegedi,Iliyan Kolev,Judit Mihály,Borislav Tzankov,Georgi Momekov,Nikolai Lambov,Krassimira Yoncheva +7 more
TL;DR: In vitro release studies showed slower release rate of sulfadiazine from carboxylic modified MCM-41 and SBA-15 mesoporous particles compared to the non modified ones, and both non loaded and drug-loaded silica materials demonstrated no cytotoxicity on Caco-2 cell line.
Journal ArticleDOI
Catalytic activity of Co/MCM-41 and Co/SBA-15 materials in toluene oxidation
TL;DR: In this paper, the pH of the impregnation solution influences the surface charge of the mesoporous support and therefore determines the strength of interaction between the cobalt precursor and the support.
Journal ArticleDOI
Controlled drug release on amine functionalized spherical MCM-41
TL;DR: In this article, a new method was developed for the quantitative determination of amino groups in surface modified mesoporous materials by the ninhydrin reaction, and a good correlation was found between the amino content of the MCM-41 materials determined by the Ninhydrin method and their ibuprofen adsorption capacity.
