Fabio C. Fonseca,Gerardo F. Goya,R. F. Jardim,Reginaldo Muccillo,Neftalí L. V. Carreño,Elson Longo,Edson R. Leite +6 more
TL;DR: In this article, a detailed characterization of the magnetic properties of Ni nanoparticles embedded in a SiO2 amorphous matrix was performed using a modified sol-gel method which resulted in Ni particles with average radius ;3 nm, as inferred by TEM analysis.
Journal ArticleDOI
Kinetic and calorimetric study of the adsorption of dyes on mesoporous activated carbon prepared from coconut coir dust.
Jeremias de Souza Macedo,Nivan B. da Costa Junior,Luís Eduardo Almeida,Eunice F.S. Vieira,Antonio R. Cestari,Iara F. Gimenez,Neftalí L. V. Carreño,Ledjane Silva Barreto +7 more
TL;DR: Calorimetric studies reveal that dyes/AC interaction forces are correlated with the pH of the solution, which can be related to the charge distribution on the AC surface, which is an economically favorable requisite for the activated carbon described in this work.
Journal ArticleDOI
Structure, morphology and functionality of acetylated and oxidised barley starches.
Shanise Lisie Mello El Halal,Rosana Colussi,Vânia Zanella Pinto,Josiane Bartz,Marjana Radünz,Neftalí L. V. Carreño,Alvaro Renato Guerra Dias,Elessandra da Rosa Zavareze +7 more
TL;DR: The structural, morphological and functional changes in acetylated and oxidized starches varied according to reaction conditions, and these characteristics are important for biodegradable film production.
Journal ArticleDOI
Films based on oxidized starch and cellulose from barley.
Shanise Lisie Mello El Halal,Rosana Colussi,Vinicius Gonçalves Deon,Vânia Zanella Pinto,Franciene Almeida Villanova,Neftalí L. V. Carreño,Alvaro Renato Guerra Dias,Elessandra da Rosa Zavareze +7 more
TL;DR: The addition of cellulose fibers in starch films can contribute to the development of films more resistant that can be applied in food systems to maintain its integrity.
Journal ArticleDOI
Histological Evaluation of Bone Repair with Hydroxyapatite: A Systematic Review.
Hellen L Oliveira,Wellington Luiz de Oliveira da Rosa,Carlos Enrique Cuevas-Suárez,Carlos Enrique Cuevas-Suárez,Neftalí L. V. Carreño,Adriana Fernandes da Silva,Thomas Normanton Guim,Odir Antônio Dellagostin,Evandro Piva +8 more
TL;DR: Although animal studies revealed a high risk of bias, the literature suggests that non-critical bone defects may heal spontaneously and without the need of a bone graft, when critical-size defects are present, the use of hydroxyapatite bone graft improves the bone repair process.
