Estudo da compactação de resíduos lignocelulósicos para utilização como combustível sólido
(Universidade Federal de São Carlos, 2011-02-08)
The production of energy from the combustion of lignocellulosic materials is an interesting way to waste recovery. Two main factors hampering the use of these residues as fuel are the low density and the high moisture ...
Filmes nanoestruturados de polianilina e argila para aplicação em sensores ambientais
(Universidade Federal de São Carlos, 2011-02-25)
In this study the development of environmental sensors began from the fabrication of nanoestrutured films obtained by the technique of Layer-by-Layer (LbL). The films of obtaining a nanocomposite material composed of ...
Síntese de microfibras biopoliméricas de zeína/hidroxipropilmetilcelulose e nanofibrila para liberação controlada de fármacos
(Universidade Federal de São Carlos, 2022-09-09)
This master’s thesis aimed to develop electrospun microfibers formed by hydroxypropylcellulose acetate succinate (HPMC-AS), zein and celulose nanofibril to be used in the release of metronidazole (MDZ) and metronidazole ...
Análise de elementos potencialmente tóxicos em ambientes aquáticos da Floresta Nacional de Ipanema
(Universidade Federal de São Carlos, 2022-02-25)
Potentially toxic elements (PTEs) constitute a class of elements composed of metals, semimetals and a non-metal. Contamination of water resources by PTEs is one of the main concerns regarding water quality and its multiple ...
