(Assoc Brasil PolimerosSao CarlosBrasil, 2010)
Evaluation of in vitro percutaneous enhancement effect of papain and pequi oil on diclofenac sodium permeation through human skin
(Divisão de Biblioteca e Documentação do Conjunto das Químicas da Universidade de São Paulo, 2008)
The purpose of this research was to determine the potential of papain and pequi oil as penetration enhancers for diclofenac sodium (DS) across human skin in vitro. The permeation studies were conducted with vertical diffusion ...
Photophysical studies and in vitro skin permeation/retention of Foscan (R)/nanoemulsion (NE) applicable to photodynamic therapy skin cancer treatment.
(AMER SCIENTIFIC PUBLISHERS, 2008)
In this work we evaluated the photophysical and in vitro properties of Foscan (R), a second-generation photosensitizer drug (PS) widely used in systemic clinical protocols for cancer therapy based on Photodynamic Therapy ...
Permeação de hidrogênio em aço ultrabaixo carbono: influências da fração recristalizada e do acabamento superficial
(Universidade Federal de Minas GeraisUFMG, 2012-11-30)
Hydrogen is a small size atom that can rapidly spread through the lattice of metal structures. This permeation may affect the mechanical properties of components from several industrial areas, especially when these parts ...
Barrier Properties and Structural Study of Nanocomposite of HDPE/Montmorillonite Modified with Polyvinylalcohol
(Hindawi Publishing Corporation, 2013-02)
In this work was studied the permeation of CO2 in films of high-density polyethylene (HDPE) and organoclay modified with polyvinylalcohol (MMTHDTMA/PVA) obtained frommelt blending. Permeation study showed that the incorporation ...
Waterborne poly(urethane-urea) gas permeation membranes for CO2/CH4 separation
(2018-03-15)
In this work, dense membranes from aqueous dispersions of poly(urethane-urea) (PUU) based on poly(propylene glycol) (PPG) and a block copolymer composed of poly(ethylene glycol) (PEG) and poly(propylene glycol) (PPG), ...
