1. Lower Susceptibility of Laser-irradiated Ti-15Mo Surface to Methicillin-resistant Staphylococcus aureus Cells Adhesion
Extensive data reported the influence of the physicochemical properties on the bacterial adhesion in biomaterials, of which surface roughness of titanium (Ti) can dictates methicillin-resistant Staphylococcus aureus (MRSA) adhesion to orthopedic implants. Herein, we investigated the influence of the Yb:YAG laser texturing of titanium-15molybdenum (TiMo-L) su

2. Surface Modification of Ti6Al4V Alloy by Pulsed Lasers: Microstructure and Hydrophobic Behavior
In many aerospace applications, it is important to produce hydro-repellent surfaces because water and ice accumulation could lead to malfunctioning of the part or component with a potential critical failure. In this study, it was investigated the texturing of a titanium alloy (Ti6Al4V) by applying a pulsed Nd:YAG laser, aimed at the surface characterization

3. Ferrite Quantification Methodologies for Duplex Stainless Steel
ABSTRACT In order to quantify ferrite content, three techniques, XRD, ferritoscope and optical metallography, were applied to a duplex stainless steel UNS S31803 solution-treated for 30 min at 1,000, 1,100 and 1,200 °C, and then compared to equilibrium of phases predicted by ThermoCalc® simulation. As expected, the microstructure is composed only by austen

4. Development and comparison of n+pn+ and n+pp+ solar cells in multicrystalline silicon
The goal of this paper is to present the development and comparison of p-type multicrystalline silicon solar cells with screen printed metallization. Industrial processes were developed to manufacture the n+pn+and n+pp+ solar cells. The n+pn+ structure was obtained with single phosphorus diffusion. The n+pp+ solar cell was developed and the p+ region was opt

6. Influência de modificações superficiais (cromagem e texturização) no comportamento tribológico de aços para fabricação de cilindros de laminação a frio / Influence of surface modifications (surface texturing and hard chromium coating) on the tribological behavior of cold rolling mills Rolls steels
O presente trabalho analisou o comportamento tribológico de modificações, geralmente utilizado em cilindros para laminação a frio. Iniciou‐se o processo com a produção das amostras a partir de um fragmento de cilindro de laminação que foi cortado, originando amostras de aproximadamente 30 x 30 mm, em que se fez tratamento térmico, retificaç�

7. Galactans: an overview of their most important sourcing and applications as natural polysaccharides
Since last decades, lot of biological and rheological properties of polysaccharides and oligosaccharides were described. Among them, galactans and more especially sulfated galactans from seaweeds have shown interesting and specific properties not only as texturing agents but also as biological active compounds on several organisms. This class of polysacchari

8. Seaweed cultivation on the Southern and Southeastern Brazilian Coast
Seaweeds are used directly as food or applied indirectly as texturing agents with gelling and thickening properties (carrageenan, agar and alginates) in many industries. They can also be used as fertilizers, animal feed, biomass for fuel, cosmetics and a source of pharmaceuticals, among other applications. The aquaculture of macroalgae is an alternative for

9. Texturização superficial eletroquímica sem mascaramento com finalidades tribológicas / Maskless electrochemical texturing surfaces for tribological purposes
A texturização superficial pode ser utilizada para melhorar o desempenho tribológico de contatos mecânicos, em particular em regimes lubrificados. O presente trabalho tem o objetivo de aprimorar uma metodologia alternativa para a texturização de superfícies baseada em princípios de usinagem eletroquímica. A dissolução eletroquímica alia rapidez,

10. Procedural textures mapping using geodesic distances / Mapeamento de texturas procedurais usando distâncias geodésicas
O mapeamento de texturas é uma técnica bastante importante para adicionar detalhamento a modelos geométricos. O mapeamento de texturas baseadas em imagens costuma ser a abordagem preferida, mas faz uso de imagens pré-computadas que são mais adequadas à representação de padrões estáticos. Por outro lado, texturas procedurais oferecem uma alternativa
