Autor: Andreia M.S. Freitas, Jean C.B. Vieira, Thaíssa S. Beck, Letícia Zibetti, Marcos A. Villetti, Clarissa P. Frizzo, Caroline R. Bender
Publikováno v: Journal of Ionic Liquids, Vol 4, Iss 1, Pp 100082- (2024)
This study explores the impact of carboxylate ionic liquids (ILs) on the phase transition properties of methylcellulose (MC) in the diluted and semi-diluted regime. Conductivity measurements were used to examine the aggregation of ILs 1-decyl-3-methy

Experimental and theoretical heat capacity of mono- and dicationic long alkyl chain imidazolium-based ionic liquids
Autor: Clarissa P. Frizzo, Jean C.B. Vieira, Dineli T.S. Ranathunga, Steven O. Nielsen, Marcos A. Villetti
Publikováno v: Journal of Ionic Liquids, Vol 2, Iss 2, Pp 100048- (2022)
Here we present the heat capacity (Cp) of a series of ten imidazolium based ionic liquids (ILs), mono- and dicationic, with chemical formula CnMIMBr (n = 2, 4, 6, 8, 10, 12, 14, and 16) and Cn(MIM)2Br2, (n = 4 and 8), respectively. The heat capacity

Autor: Bruno L. Hennemann, Guilherme S. Moleta, Ana L. Fuchs, Marcos A. Villetti, Bruna L. Kuhn, Camila R. Rampelotto, Alisson V. Paz, Cristiane de Bona da Silva, Clarissa P. Frizzo
Publikováno v: Ultrasonics Sonochemistry, Vol 72, Iss , Pp 105446- (2021)
The aim of this work was to evaluate the influence of US on the properties of the fluconazole emulsions prepared using imidazolium-based ILs ([Cn C1im]Br). The effects of the preparation method (mechanical stirring or US), US amplitude, alkyl chain l

Avaliação da fotoestabilidade do ácido rosmarínico: efeito da radiação ultravioleta, pH e peróxido de hidrogênio
Autor: Marcos Antonio Villetti, Thiane Deprá Saravalle, Brenda Bopp Baptista, Carmen Luisa Kloster, Clarissa Piccinin Frizzo
Publikováno v: Revista Eletrônica Científica da UERGS. 8:228-235
As espécies reativas de oxigênio são essenciais em vários processos biológicos, porém, quando em excesso causam estresse oxidativo levando a doenças neurodegenerativas e cardiovasculares e ao envelhecimento precoce. Os antioxidantes atuam de f

Autor: Jean C. B. Vieira, Marcos A. Villetti, Nilo Zanatta, Nícolas Krüger, Alisson V. Paz, Clarissa P. Frizzo
Publikováno v: Journal of Solution Chemistry. 50:240-256
In this work, the heating profile of water, dimethyl sulfoxide (DMSO), acetonitrile (CH3CN) and ethanol (EtOH) and their solutions containing monocationic (CnMIMBr, n = 4, 6, 8, 10, 12, 14 and 16) and dicationic (di-CnMIMBr, n = 4, 6, 8 and 10) imida
