Study of the influence of cobalt in the high formability of the Au-Fe system

Abstract: Since ancient times, gold has been used due to its especial properties. Among those properties are the resistance to corrosion (for being noble), its high electrical and thermal conductivity, and also its conspicuous coloration. Gold has been applied in a div

Kinetics of nopyl acetate synthesis by homogeneously catalyzed esterification of acetic acid with nopol

Abstract: The esterification of nopol with acetic acid to produce nopyl acetate using sulfuric acid as homogeneous catalyst was studied. The reactions were carried out in a batch reactor, at different temperatures (50, 60, 70 and 80 °C), catalyst concentrations (0.0184

Corrosion protection in saline environment of a carbon steel coated (aluminum & three-layer painting system) by eats

Abstract: This paper presents a comparative study on corrosion protection of low-carbon steel coated with two different painting systems. The first set of samples was coated with an aluminum layer of primer deposited by Electric Arc Thermal Spray (EATS), after which tw

Small-signal stability analysis of dc microgrids considering electric vehicles
Alejandro Garcés-Ruiz

Abstract: This paper presents a generalized model for small signal stability in dc microgrids considering electric vehicles. The proposed model considers four type of terminals, namely: constant power, constant voltage, constant current and constant impedance. A Newton

Polycaprolactone- Chitosan- Ag coatings on Ti6Al4V: Critical synergic aspects analyzed by Raman, EFM and contact angle

Abstract: The Ti6Al4V presented a natural oxide layer that increased the corrosion resistance of the material but decreased the physicochemical compatibility with the bone tissue. The use of polymeric coatings on Ti6Al4V allows the creation of an interface that promote

Model for microhardness profile prediction of annealed AISI 1045 steel cylindrical bars subjected to torsion

Abstract: In this work, the effect of the torsion process angle of twist and distance from the center of cylindrical bars on the microhardness profile of annealed AISI 1045 steel was studied. The results showed that the microhardness increase with the evaluated paramet
