Optical antennas/nanoantennas are optical elements that have gained highlight in this decade and have potential application in several branches of photonics/plasmonics, such as, optical sensors, lasers, solid state lighting, ...
Dynamic analysis of a new piezoelectric flextensional actuator using the J1-J4 optical interferometric method
(2005-12-01)
Piezoelectric actuators are widely used in positioning systems which demand high resolution such as scanning microscopy, fast mirror scanners, vibration cancellation, cell manipulation, etc. In this work a piezoelectric ...
Production and heat treatment of cast graphitic steels with additions of niobium
(2006-12-01)
The optimal combination of the mechanical characteristics of austempered spheroidal graphitic cast steel together with modern casting techniques yielded an economically promising product. The maximum potential of the usage ...
Influence of thermal treatments in the corrosion behaviour of HVOF Cr 3C2-NiCr coatings
(2001-12-01)
Thermal spray coatings as Cr3C2-NiCr obtained by high velocity oxy-fuel spraying (HVOF) are mainly applied due to their behaviour against aggressive erosive-abrasive and corrosive atmospheres and their thermal stability ...
