1. Designing and fabrication of a low-cost dip-coater for rapid production of uniform thin films
In this work, a self-made dip-coater equipment was developed for the fabrication of thin films. The assembly of the apparatus was carried out using simple mechanical and electronic pieces, recycle parts, and spending an inexpensive budget suitably. The production, software design, and features of the device were focused on the sol-gel dip-coating method, whi

3. Translucency and color stability of resin composite and dental adhesives as modeling liquids – A one-year evaluation
Abstract The aim of this study is to evaluate the influence of modeling liquids on the translucency and color shade of resin composites (RCs) after one year of storage. RC specimens were prepared using either a conventional insertion technique (control; without modeling liquid) or a restorative dental modeling insertion technique (RDMIT) with dental adhesive

5. Effects of modeling liquid/resin and polishing on the color change of resin composite
Abstract Modeling liquids/resins have been used to build up resin composite (RC) restorations, although there is a lack of information regarding their effects on the color stability of the latter. Therefore, the purpose of the present study was to evaluate the effects of the presence of modeling liquid between layers of RC and the finishing/polishing state o

6. Corrosion behavior of zirconia in acidulated phosphate fluoride
ABSTRACT Objective The corrosion behavior of zirconia in acidulated phosphate fluoride (APF) representing acidic environments and fluoride treatments was studied. Material and Methods Zirconia rods were immersed in 1.23% and 0.123% APF solutions and maintained at 37°C for determined periods of time. Surfaces of all specimens were imaged using digital mi

7. Effect of the Fuels Glycine, Urea and Citric Acid on Synthesis of the Ceramic Pigment ZnCr2O4 by Solution Combustion
AbstractIn this study, ceramic nanopigment ZnCr2O4was prepared by solution combustion using glycine, urea and citric acid as fuels. The objective is to study the influence of fuel on the morphology and the diffuse reflectance spectrum. The nanoparticles were characterized by field emission scanning electron microscopy (FESEM), the phase was investigated by X

9. Photorefractive digital holographic microscopy: an application in the microdevices surfaces
In this work, we present a Photorefractive Digital Holographic Microscopy (PRDHM) technique based on the writing-reading holographic process in photorefractive Bi12TiO20 (BTO) crystal using the numerical reconstruction of the phase and amplitude image performed by a Digital Holographic Microscopy (DHM) method. We demonstrate that a holographic reconstructed

10. Long term evaluation of morphometric and ultrastructural changes of testes of alloxan-induced diabetic rats
PURPOSE: To evaluate in a long term the morphometric and ultrastructural changes in seminiferous tubules (ST) of normal and diabetic rats, and to correlate any changes with animal age and diabetes duration. METHODS: Sixty male Wistar rats, three months-old, were randomly divided into two groups: 30 non-diabetic controls (N) and 30 alloxan untreated diabetic

11. AUTOMATIC QUANTIFICATION OF METALLIC IRON IN SELF-REDUCING IRON ORE BRIQUETTES BY DIGITAL MICROSCOPY / QUANTIFICAÇÃO AUTOMÁTICA, POR MICROSCOPIA DIGITAL, DO FERRO METÁLICO EM BRIQUETES AUTORREDUTORES DE MINÉRIO DE FERRO
A produção do ferro primário, intermediário na produção do aço, é realizada majoritariamente pela rota tradicional do alto-forno. No entanto, tecnologias alternativas estão aumentando suas participações no mercado. Dentre elas, a tecnologia emergente brasileira de autorredução Tecnored é bastante promissora e é objeto de estudo desta disserta�
