1. Synthesis of New Phenolic-Schiff Base and Its Application as Antioxidant in Soybean Biodiesel and Corrosion Inhibitor in AISI 1020 Carbon Steel
New Schiff base compound N, N’-bis-(4-hexadecanate)-salicylethylenediamine (named IM) was synthesized, and characterized via infrared and nuclear magnetic ressonance spectroscopies. IM was tested as corrosion inhibitor and antioxidant in soybean biodiesel. Corrosion studies were developed with AISI 1020 carbon steel in a three-step accelerated corrosion as

2. Desenvolvimento e caracterização de dispositivo de PLLA/Trietil-Citrato associado à derme suína acelular para reparação de lesões cutâneas / Development and characterization of PLLA/Triethyl citrate device associated to acellular dermal matrix to repair cutanous wounds
One of the challenges of the Tissue Engineering is to promote a better functioning of organs and tissues damaged by diseases or traumas. With target for developing a biphasic device for future regeneration and dermal application in Tissue Engineering and Regenerative Medicine, fibroblasts from VERO cell line were cultivated on a porcine acellular dermal matr

3. Estudos da correlação estrutura-função da enzima Clorocatecol 1,2-Dioxigenase de Pseudomonas putida / Studies of the structure-function correlation of the chlorocatechol 1,2-dioxygenase enzyme from Pseudomonas putida
O intenso uso de compostos orgânicos em conjunto com o grande avanço industrial culminou em um enorme acúmulo de poluentes orgânicos no meio ambiente. Dentre estes poluentes têm-se destacado a presença de hidrocarbonetos aromáticos altamente tóxicos e resistentes à degradação física, química, fotolítica e biológica. Desta maneira, uma nova for

4. INFLUENCE OF SYNTHESIS PARAMETERS IN THE PROPERTIES OF MCM-22 ZEOLITE / INFLUÊNCIA DOS PARÂMETROS DE SÍNTESE NAS PROPRIEDADES DA ZEÓLITA MCM-22
MCM-22 zeolite was first synthesized by Mobil researchers in 1990. It is an aluminosilicate with molecular sieve characteristics and several applications in catalytic processes because of its two independent pore systems. In this work, the MCM-22 zeolite synthesis conditions were studied using both static as stirred hydrothermal treatment. Molar composition

5. Influência do modo de ativação e de uma restauração simulada de porcelana no grau de conversão e na dureza superficial de um cimento resinoso auto-adesivo de cura dual / Influence of polymerization mode and a simulated ceramic restoration on degree of conversion and surface hardness of a dual-cured self-adhesive resin cement
The aim of this study was to evaluate the degree of conversion (DC) and the microhardness of a self-adhesive resin cement under different activation protocols, immediately and after 24 hours of the beginning of the polymerization, and, defining cement regarding monomer composition, average diameter of the inorganic fillers and the percentage by weight of the

6. Ditiocarbamatos derivados do glicoluril, ácido úrico, ácido parabânico e hidantoína: compostos de coordenação e uso como inibidores de corrosão do bronze
This thesis work is about dithiocarbamates compounds, their synthesis, study and application as corrosion inhibitors. The dithiocarbamates herein studied were synthesized from four substances: glycoluril, uric acid, parabanic acid and hydantoin. The pro-ligands were synthesized through reaction with CS2 and NaOH, characterized via elemental analysis (CHN) an

7. Modo de ação de xilanases de Aspergillus sp 2M1 em sequencias de branqueamento de polpas de Eucalyptus grandis totalmente livres de cloro
Unbleached Eucalyptus grandis kraft pulps were submitted to TCF bleaching sequences (XOP - Xylanase/Oxygen/Peroxide and XZP -Xylanase/Ozone/Peroxide) using a non-commercial enzyme (Asperzyme 2M1) at the X stage. During the enzymatic treatment, the xylanase charge, inducted carbon source, incubation temperature and incubation time were changed. The pulp sampl

8. Dinamica e reatividade de superficie de poli (dimetilsiloxano)s
Crosslinked polydimethylsiloxane (PDMS) heated at temperatures between 200 and 280°C for short periods (one-half to two hours), reveals a partially thermoplastic behavior. Earlier studies on silicone describe the phenomena occurring under heating as due to chemical reactions leading to the formation of oligomers and oxidation products, which cause degradati
