1. Desenvolvimento, caracterizaÃÃo e estudo de permeaÃÃo cutÃnea de diclofenaco de dietilamÃnio em sistemas tÃpicos nanoemulsionados
The nanoemulsions (NE) are transparent, isotropic and thermodynamically stable systems, formed spontaneously under a specific set of experimental conditions from mixtures of water and oil phases stabilized by a surfactant or a mixture of surfactant and cosufactant. Because of their properties, especially the ability to carry lipophilic and hydrophilic drugs

2. Utilização de microemulsões como agentes modificadores de superfícies para remoção de íons metálicos
The heavy metals are used in many industrial processes and when discharged to the environment can cause harmful effects to human, plants and animals. The adsorption technology has been used as an effective methodology to remove metallic ions. The search for new adsorbents motivated the development of this research, accomplished with the purpose of removing C

3. Microemulsões a base de óleos vegetais: formação, propriedades e emprego na descontaminação EX-SITU de Solo / Vegetable oil-based microemulsions: formation, properties and application for "exsitu" soil decontamination
In the present project, we were interested in assessing the use of Brazilian vegetable oils in the "ex-situ" decontamination of soils from polycyclic aromatic hydrocarbons (PAHs). In this process, contaminated soil is treated with a microemulsion (µE) composed of water (W) /commercial non-ionic surfactant (S) C9/11EO4 /oil (O). The latter term refers to the

4. Formulation Development and Bioavailability Evaluation of a Self-Nanoemulsified Drug Delivery System of Oleanolic Acid
This study aims to formulate and evaluate bioavailability of a self-nanoemulsified drug delivery system (SNEDDS) of a poorly water-soluble herbal active component oleanolic acid (OA) for oral delivery. Solubility of OA under different systems was determined for excipient selection purpose. Four formulations, where OA was fixed at the concentration of 20 mg/
