No. of bitstreams: 0 Previous issue date: 2020-12-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Bacterial cellulose (BC) membranes biosynthesized by Komagataeibacter rhaeticus AF1 strain were used as a platform for precipitating cerium-doped calcium phosphates (Ce:Ca...
Utilização da sílica gel recuperada como fase estacionária para purificação do ...
Maia, Juciely Carvalho; Nobre, Francisco Xavier; Freitas, Alessandra Ribeiro; Vieira, Ewerton Gomes; Rios, Maria Alexsandra de SousaOne of the main purposes of Green Chemistry is the development and application of chemical processes to reduce or eliminate the use and generation of hazardous substances to the environment. Thus, considering the importance of environmentally safe methods, this work presents an alternative method of silica gel recovery aiming its use in chromatography column. In order to verify the efficiency of the procedure, ...
Development of composite scaffolds based on cerium doped-hydroxyapatite and nat...
Santos, Marcus Vinicius Beserra dos; Rocha, Lorenna Bastos Nogueira; Vieira, Ewerton Gomes; Oliveira, Ana Leite; Lobo, Anderson OliveiraHydroxyapatite (HAp) is a ceramic material composing the inorganic portion of bones. Ionic substitutions enhance characteristics of HAp, for example, calcium ions (Ca2+) by cerium ions (Ce3+). The use of HAp is potentialized through biopolymers, cashew gum (CG), and gellan gum (GG), since CG/GG is structuring agents in the modeling of structured biocomposites, scaffolds. Ce-HApCG biocomposite was synthesized us...
