2. Characterization of Ti-35Nb alloy surface modified by controlled chemical oxidation for surgical implant applications
ABSTRACT Titanium-Niobium alloys have been studied for biomedical applications due to their satisfactory biocompatibility. In order to improve the long-term implantation, surface modification techniques have been developed to generate suitable topography, roughness, chemical composition, surface energy, etc. Considering this approach, the present work aimed

3. Influence of Zirconia-Coated Bioactive Glass on Gingival Fibroblast Behavior
Resumo O objetivo deste estudo foi o desenvolvimento de um recobrimento de vidro bioativo sobre a zircônia (Zr) para modular o fenótipo de fibroblastos gengivais. Para este propósito, partículas de Biosilicato® (6 mg/mL) em um veículo a base de água/álcool isopropílico (1:1) foram aplicadas sobre discos de zircônia seguido por tratamento térmico a

4. Análise do Desempenho do Modelo WRF num Episódio de Vento Intenso e Persistente num Grande Reservatório Tropical
Resumo O presente estudo apresenta uma aplicação do modelo de mesoescala WRF à simulação de um episódio de vento intenso e persistente que ocorre com frequência irregular no reservatório de Guapé, MG. Tal evento altera a rotina da população na região, fazendo com que, por exemplo, a embarcação que faz a travessia entre as cidades de Guapé e Ca

5. Electrolytic polishing of compacted graphite iron for revealing subsurface graphite of honed cylinders
ABSTRACT The superficial characteristics of honed surfaces are relevant for the tribological performance of cylinders of internal combustion engines (MCI). Recent studies found a correlation between the occurrence of the phenomenon called folded metal and the presence of graphite of cast irons. However, the honing process tends to overlap the graphite, such

6. Surface morphologic evaluation of orthodontic bonding systems under conditions of cariogenic challenge
Abstract: Orthodontic bonding systems are submitted to demineralization and remineralization dynamics that might compromise their surface smoothness, and favor biofilm aggregation and caries development. The aim of the present study was to evaluate the effects of a cariogenic challenge model (in vitro pH-cycling model) on the surface roughness and topography

7. Surface Topography, Gloss and Flexural Strength of Pressable Ceramic After Finishing-Polishing Protocols
Resumo O objetivo deste estudo foi avaliar o efeito de diferentes protocolos de acabamento e polimento na rugosidade da superfície, brilho, resistência à flexão biaxial e morfologia de cerâmica prensada. Trinta discos de cerâmica (12x1 mm) foram produzidos e divididos em cinco grupos (n=6): CT- controle (glaze); DA- ponta diamantada de granulação fin

8. Multiple-peak and single-peak dental curing lights comparison on the wear resistance of bulk-fill composites
Abstract: The effects of tooth brushing could affect the long-term esthetic outcome of composite restorations. This study evaluated the effect of two different emission spectrum light-curing units on the surface roughness, roughness profile, topography and microhardness of bulk-fill composites after in vitro toothbrushing. Valo (multiple-peak) and Demi Ultra

9. Effect of grinding and aging on subcritical crack growth of a Y-TZP ceramic
Abstract This study aimed to investigate slow crack growth (SCG) behavior of a zirconia ceramic after grinding and simulated aging with low-temperature degradation (LTD). Complementary analysis of hardness, surface topography, crystalline phase transformation, and roughness were also measured. Disc-shaped specimens (15 mm Ø × 1.2 mm thick, n = 42) of a ful

10. Can whitening toothpastes maintain the optical stability of enamel over time?
Abstract Besides the effects on the health of individuals, cigarette smoking can also interfere with the appearance of their teeth. Objective: To evaluate the effect of cigarette smoking-toothbrushing-cycling (CSTC) with whitening toothpastes on the roughness and optical behavior of bovine enamel for eight weeks. Material and Methods: Thirty bovine dentin/

11. Decellularized Bovine Articular Cartilage Matrix Reinforced by Carboxylated-SWCNT for Tissue Engineering Application
ABSTRACT Nanotubes with their unique properties have diversified mechanical and biological applications. Due to similarity of dimensions with extracellular matrix (ECM) elements, these materials are used in designing scaffolds. In this research, Carboxylated Single-Wall Carbon Nanotubes in optimization of decellularized scaffold of bovine articular cartilage

12. Mechanical behavior of yttria-stabilized tetragonal zirconia polycrystal: Effects of different aging regimens
Abstract This study aimed to characterize and compare the effect of different aging regimens on surface characteristic (topography and roughness), structural stability (phase transformation) and mechanical performance (Weibull analysis) of a Y-TZP ceramic. Discs (15 × 1.2 mm; VITA In-Ceram YZ) were prepared according to ISO 6872-2015 for biaxial flexural st
