Photopolymerization-assisted self-assembly as a strategy to obtain a dispersion of very high aspect ratio nanostructures in a polystyrene matrix
(Pergamon-Elsevier Science Ltd, 2018-10)
Very high aspect ratio nano-objects dispersed in a polymer matrix impart a number of desired characteristics to the material, such as barrier properties to the diffusion of small molecules. Commonly, these dispersions are ...
Large cation-selective pores from rat liver peroxisomal membranes incorporated to planar lipid bilayers
(1986)
Fusion of a highly purified fraction of rat liver peroxisomal membranes to planar lipid bilayers incorporates large, cation-selective voltage-dependent pores. ThePK/PCl ratio of these pores, estimated in KCl gradients, is ...
CFTR in K562 human leukemic cells
(American Physiological Society, 2003-08)
In this study, the expression and functional characterization of CFTR (cystic fibrosis transmembrane regulator) was determined in K562 chronic human leukemia cells. Expression of the CFTR gene product was determined by ...
Synthesis, characterization and evaluation of phosphorylated resins in the removal of Pb(2+) from aqueous solutions
(SPRINGER, 2011)
Phosphinic-derivative poly(styrene-co-divinylbenzene)-based on PS-DVB copolymers with different porosity degrees have been prepared by aromatic electrophilic substitution reaction using PCl(3)/AlCl(3) followed by base-promoted ...

(Universidade Estadual de Ponta GrossaBrasilDepartamento de Ciências FarmacêuticasPrograma de Pós-Graduação em Ciências FarmaceuticasUEPG, 2020)
Estudio correlacional entre la credibilidad del testimonio y psicopatía en hombres procesados por delitos sexuales (propuesta de investigación)
(Universidad Santo TomásEspecialización Psicología Jurídica y ForenseFacultad de Psicología, 2017)
Carrying out a correlative study, between two groups imprisoned for sexual abuse (AS) of the penances Las Heliconias and La Picota, against the credibility of testimony and presence of psychopathic traits, through the use ...
Micelas de copolímeros em bloco à base de maltoheptaose contendo ftalocianina de magnésio para aplicação em terapia fotodinâmica
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2022-02-15)
The development of new nanocarriers for the so-called third-generation photosensitizers (FS) has contributed significantly to the evolution of photodynamic therapy (PDT). Due to its maximum absorption at wavelengths within ...
Síntese de copolímeros em bloco por reações one-pot com processos RAFT e ROP simultâneos
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2016-02-04)
The present work describes a methodology of controlled synthesis of block copolymers by one-pot reactions involving simultaneous RAFT and ROP processes mediated by a bifunctional compound which acts as a chain transfer ...
Síntese de partículas submicrométricas de carbonato de cálcio a partir de sais inorgânicos utilizando polímeros lineares como modificadores de cristalização
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2017)
In this work, we report the synthesis of submicrometer calcium carbonate
particles using the simplest approach of mixing solutions of calcium chloride
and ammonium carbonate inorganic precursors in presence of ...
