1. Analysis and evaluation of structural properties of Co3O4 microparticles obtained at low temperature
Abstract In the present research, the synthesis of cobalt oxide Co3O4 was carried out using the sol-gel technique with subsequent heat treatment at 225 and 235 °C. The final product obtained was characterized by X-ray diffraction (XRD), showing a pure crystalline phase of Co3O4, cell parameters a=b=c=8.071 Å, and a volume of 525.7 Å3. The particle size wa

2. COMPREENDENDO OS MECANISMOS DE CORROSÃO DE LIGAS DE AL-CU-LI: UMA INVESTIGAÇÃO ATRAVÉS DE TÉCNICAS ELETROQUÍMICAS GLOBAIS E LOCAIS
In this study, the corrosion mechanism of an Al-Cu-Li alloy manufactured by two different treatment routes (T3 and T851) was evaluated by immersion and electrochemical tests in solutions containing chloride ions (Cl-). For both alloys, the formation of cavities on the surface was associated with micrometer-sized intermetallics (IM’s), however, in addition

3. PEEK Physical Surface Modification: Evaluation Of Particles Leaching Process
Polyetheretherketone (PEEK) has been prominent in orthopedic implants; however, it is inert, preventing interaction between the implant and adjacent bone tissues. One way to overcome this characteristic is physical modification its on surface by particle leaching promoting greater osseointegration. The objective of this research was to develop and characteri

4. Ultrastructure of Zika virus particles in cell cultures
Zika virus (ZIKV) has infected thousands of Brazilian people and spread to other American countries since 2015. The introduction of ZIKV brought a strong impact to public health in Brazil. It is of utmost importance to identify a susceptible cell line that will enable the isolation and identification of the virus from patient samples, viral mass production,

5. Macrophages adhesion rate on Ti-6Al-4V substrates: polishing and DLC coating effects
Abstract Introduction Various works have shown that diamond-like carbon (DLC) coatings are able to improve the cells adhesion on prosthesis material and also cause protection against the physical wear. On the other hand there are reports about the effect of substrate polishing, in evidence of that roughness can enhance cell adhesion. In order to compare and

6. Microparticles containing guaraná extract obtained by spray-drying technique: development and characterization
AbstractGuaraná (Paullinia cupana Kunth, Sapindaceae) is well known for its dietary and pharmaceutical potential, and the semipurified extract of guaraná shows antidepressant and panicolytic effects. However, the low solubility, bioavailability and stability of the semipurified extract limit its use as a component of pharmaceutical agents. Delivery of the

7. Desenvolvimento de vetores não virais para entrega gênica baseados na cadeia leve de dineína Rp3 = : Development of non viral vectors for gene delivery based on dynein light chain Rp3 / Development of non viral vectors for gene delivery based on dynein light chain Rp3
Gene delivery is a promising technique with great medical potential that consists in the introduction of exogenous nucleic acids, and can be applied for gene therapy as well as DNA vaccination. However, its use is still limited by the lack of an ideal delivery vector, which is both safe and efficient. Although much more effective, viral vectors still raise s

11. Structural and dynamical properties of a quasi-onedimensional classical binary system / Estudo das propriedades estruturais e dinÃmicas de um sistema binÃrio quasi-unidimensional.
The aim of this work is to study the structural and dynamical properties of a classical binary system of charged particles confined in a two dimensional channel. Such a system is described in the literature as quasi-unidimensional, and its relevance is supported by the possibility of technological applications, shown recently in the scientific literature, an

12. Equilibrio de osmossedimentação sob-gravidade : polidispersões aquosas de prata
This thesis shows results obtained from theoretical and experimental work on osmosedimentation of silver sols under gravity. The osmosedimentation velocity is shown to be strongly dependent on sol concentration and cell geometry. The results show the existence of a osmosedimentation equilibrium state. In this state, the particle distribution along the cells,
