Journal ArticleDOI
Photodegradation of methylene blue by in situ generated titania supported on a NaA zeolite
Diego Ivan Petkowicz,Rodrigo Brambilla,Claudio Radtke,Carlos Daniel Silva da Silva,Zênis Novais da Rocha,Sibele B. C. Pergher,João Henrique Zimnoch dos Santos +6 more
TL;DR: In this paper, the degradation of methylene blue dye was evaluated for a series of in situ generated titania resulting from the impregnation of TiCl 4 into NaA zeolites, which were synthesized using alternative silicon sources, namely rice husk and chrysotile, and submitted to different treatments.
Journal ArticleDOI
Selective silica-based sorbent materials synthesized by molecular imprinting for adsorption of pharmaceuticals in aqueous matrices
Everton C. Morais,Gabriel G. Correa,Rodrigo Brambilla,João Henrique Zimnoch dos Santos,Adriano G. Fisch +4 more
TL;DR: In this article, a molecular imprinting technique using an acid-catalyzed sol-gel process and the following drugs as templates: fluoxetine, gentamicin, lidocaine, morphine, nifedipine, paracetamol, and tetracycline was used.
Journal ArticleDOI
Octadecylsilane-modified silicas prepared by grafting and sol–gel methods
Rodrigo Brambilla,Gilvan P. Pires,João Henrique Zimnoch dos Santos,Marcia Silva Lacerda Miranda,B. Chornik +4 more
TL;DR: Cape is thanked for the grant as mentioned in this paper and FNPq and FAPERGS/PRONEX are thanked for partial financement for partial feasibility study of the project.
Journal ArticleDOI
The interaction of encapsulated pharmaceutical drugs with a silica matrix.
Everton C. Morais,Gabriel G. Correa,Rodrigo Brambilla,Claudio Radtke,Ione Maluf Baibich,João Henrique Zimnoch dos Santos +5 more
TL;DR: A correlation was observed between the textural characteristics of the solids and the spectroscopic data, suggesting that the amine groups from the pharmaceuticals were more perturbed upon encapsulation, suggesting the possibility of a hydrogen bonding interaction between the drug and the silica via electron donation from theAmine group to thesilica framework.
Journal ArticleDOI
Characterization of MAO‐Modified Silicas for Ethylene Polymerization
Mohamad mehdi Mortazavi,Saeid Ahmadjo,João Henrique Zimnoch dos Santos,Hassan Arabi,Mehdi Nekoomanesh,Gholamhossein Zohuri,Rodrigo Brambilla,Griselda B. Galland +7 more
TL;DR: In this paper, a series of methylaluminoxane (MAO)-modified PQ and EP 12 silicas, calcined at 110, 250, and 450 C, were prepared.
