Resumo IPEN-doc 16197 Hydrogel: the influence of oxygen on the properties of PVP membranes2009 - ALCANTARA, M.T.S.; LUGAO, A.B.The aim of this study is to verify the influence of dissolved oxygen on the synthesis of PVP hydrogels membranes. The hydrogels were prepared in different conditions (i.e., with oxygen dissolved and replacing the oxygen dissolved by nitrogen). The samples were crosslinked by gamma rays. The gel fraction and swelling kinetic in hydrogels membranes were analyzed to study the influence of natural oxygen in membranes prepared. The swelling results showed large differences on cross linking densities from samples irradiated with and without oxygen, however no difference was verified on gel fraction.Resumo IPEN-doc 19801 Hidrogel com nanopartículas de prata para feridas infectadas com bactéria multiresistente2013 - LUGAO, ADEMAR B.; LINCOPAN, NILTON; SANTOS, PRISCILA M. dos; RIELLA, HUMBERTO G.; ALCANTARA, MARA T.S.Artigo IPEN-doc 10629 Estudo da reticulacao induzida por radiacao ionizante de poli(vinil pirrolidona)(PVP)/carboximetil celulose (CMC)2005 - ALCANTARA, M.T.S.; CHIRINOS, H.; AMARAL, R.H.; ROGERO, S.O.; LUGAO, A.B.Artigo IPEN-doc 19590 Estudo das propriedades mecânicas de hidrógeis utilizando planejamento experimental2013 - ALCANTARA, MARA T.S.; TAQUEDA, MARIA E.S.; GIANNINI, DANIELLE R.; BRANT, ANTONIO J.C.; RIELLA, HUMBERTO G.; LUGAO, ADEMAR B.Artigo IPEN-doc 15157 The influence of water quality on properties of hydrogel membranes prapared by ionizing radiation2009 - ALCANTARA, MARA T.S.; SISTI, CRISTINA; FURUSAWA, HELIO A.; LUGAO, ADEMARArtigo IPEN-doc 17084 Effect of different plasticizers on poly(N-vinyl-2-pyrroplidone) hydrogels cross-linked by radiation2011 - ALCANTARA, MARA T.S.; GIANNINI, DANIELLE R.; BRANT, ANTONIO J.C.; RIELLA, HUMBERTO G.; LUGAO, ADEMAR B.Artigo IPEN-doc 18236 Influence of dissolution processing of PVA blends on the characteristics of their hydrogels synthesized by radiation - Part I: Gel fraction, swelling, and mechanical properties2012 - ALCANTARA, M.T.S.; BRANT, A.J.C.; GIANNINI, D.R.; PESSOA, J.O.C.P.; ANDRADE, A.B.; RIELLA, H.G.; LUGAO, A.B.
