Aplicação de nanopartículas em filmes utilizados em embalagens para alimentos
(Universidade Federal de São Carlos, 2009-04-30)
Dispersions composed of chitosan (CS) were obtained by the template polymerization (CS-PMAA) and ionotropic gelatinization (CS-TPP). The nanoparticles were analyzed by FT-IR analysis, particle size, zeta potential, electron ...
Síntese e caracterização de hidrogéis de poliacrilamida e metilcelulose para liberação controlada de pesticidas
(Universidade Federal de São Carlos, 2009-05-07)
In this thesis, the preparation and characterization of hydrogels of methylcellulose (MC) mechanically supported in polyacrylamide (PAAm) network for controlled release of pesticide were reported. The controlled release ...
Novo enfoque no estudo da transição de fase composicional da solução sólida ferroelétrica (Pb,Ca)TiO3
(Universidade Federal de São Carlos, 2006-11-13)
Ferroelectric materials have a vast application in modern industry as data storage devices. Some of this materials, as the ferroelectric oxides class ABO3, have phase transitions with the alteration of of the lattice ...
Simulação do crescimento de filmes sobre metais. O caso voltamétrico
(Universidade Federal de São Carlos, 2008-07-02)
In this work the anodic film growth on metals has been studied, under voltammetric conditions by simulation. It was supposed that: a) the films are ultrathin, i.e., the concentration gradient contributions for the ionic ...
