Microencapsulação por gelificação iônica e interação eletrostática do corante de buriti (Mauritia flexuosa L. f.)
(Universidade Estadual Paulista (Unesp), 2015-05-04)
The aim of this work was to study the microencapsulation process by ionic gelation associated with the electrostatic interaction of the dye extracted from the buriti pulp. Initially the surface tension, density and rheological ...
Metodologia para visualização de cristais de parafinas em óleo formulado através de microscopia óptica de campo claro
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em Engenharia MecânicaUTFPR, 2019-12-09)
Much of the Brazil oil production comes from offshore (deepwater) platforms. These oils, rich in paraffin, are transported to the Earth coast by pipelines that pass through the seabed, where the average temperature is ...
Desenvolvimento de processo de encapsulamento de anticorpos IgY visando manutenção da viabilidade
(Universidade Tecnológica Federal do ParanáLondrinaBrasilTecnologia de AlimentosUTFPR, 2018-11-28)
The microparticles are composed of an encapsulating material which isolates an active substance in order to be preserved, being released only at the appropriate time and place. Antibodies are able to recognize the pathogens ...
Produção de nanopartículas de quitosana e aplicação como revestimento em blendas de amido de mandioca e poli (ácido lático)
(LondrinaBrasil, 2020)
Chitosan is a biopolymer with wide application in the cosmetic, textile, food and agriculture areas. In this work chitosan nanoparticles (CNP) was produced by ionic gelation and used as coating in starch (TPS) and poly(lactic ...
Estudo de parâmetros de síntese do gel termossensível Poli(N-isopropilacrilamida).
(Universidade Federal de Minas GeraisUFMG, 2005-10-28)
In this work, the main parameters involved in the Poly (N-isopropylacrylamide) temperature-sensitive gel synthesis were studied, in order to evaluate their influence in the characteristics of the obtained gel. This study ...
Síntese de micro / nanopartículas de óxido de cálcio por queima de alginato usando via verde
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2018-04-05)
The present study describes the synthesis of micro / nanoparticle by the method of combustion of alginate associated with ions through gelling, verifying if the properties of the metallic oxides can be influenced by gelation ...
Avaliação da utilização de beads de líquido iônico na adsorção e remoção de cromo em efluente sintético
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia QuímicaUTFPR, 2021-08-25)
Room temperature organic salts, also called ionic liquids (ILs), have been studied to produce polymeric beads in the last decade. Ionic liquids are widely studied, due to the malleability of their structure, in the ...
