Films from resistant starch-pectin dispersions intended for colonic drug delivery
(2014-01-01)
Free films were obtained by the solvent casting method from retrograded starch-pectin dispersions at different polymer proportions and concentrations with and without plasticizer. Film forming dispersions were characterized ...

Aditivos de formulação na formação de filmes isolados de etilcelulose. estudos físico-químicos e morfológicos
(Colegio Farmaceuticos Provincia de Buenos Aires, 2009-11-01)
Formulation Additives on Formation of Films isolated from Ethylcellulose. Physicochemical and Morphological Studies. In this work were developed free films from Surelease (R), additives alpha-GOS (alfa-glucooligosaccharide) ...
Chemical potential and free energy of nanoconfined water in Newton black films
(Elsevier Science, 2018-09)
In this work we investigate possible approximations to the free energy and chemical potential of water within a Newton black film as a natural nanoconfinement. As a first step we explore the different approximations in a ...
Thickness dependence of structure and piezoelectric properties at nanoscale of polycrystalline lead zirconate titanate thin films
(2013-05-14)
Lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were deposited by a polymeric chemical method on Pt(111)/Ti/SiO2/Si substrates to understand the mechanisms of phase transformations and the effect of film thickness ...

Resistant starch/pectin free-standing films reinforced with nanocellulose intended for colonic methotrexate release
(2017-02-10)
Although resistant starch/pectin (RS/P) films have previously displayed suitable properties for colon-specific drug delivery, nanocomposite films were developed aiming to enhance physicochemical, thermal, mechanical and ...
Electromechanical properties of calcium bismuth titanate films: A potential candidate for lead-free thin-film piezoelectrics
(American Institute of Physics (AIP), 2006-02-13)
CaBi4Ti4O15 (CBTi144) thin films were evaluated for use as lead-free thin-film piezoelectrics in microelectromechanical systems. The films were grown by the polymeric precursor method on (100)Pt/Ti/SiO2/Si substrates. The ...
