Ferroelectric ceramic/polymer composite for measuring X-ray intensity in the ortovoltage range
(IEEE, 2007-01-01)
Pyroelectric sensors work as a thermal transducer converting the non-quantified thermal flux into the output measurable quantity of electrical charge, voltage or current. Ferroelectric ceramics and ferroelectric polymers ...

(2002-12-01)
This job aim has been to study the aqueous corrosion of the 7xxx heattreatable aluminium alloys, used in the aeronautical industry. The 7010, 7050 and 7475 alloys, have been supplied in the T7 condition and submitted to ...
The use of thermogravimetric analysis to characterize the metallic slag aggregates in structural concrete
(2020-01-01)
Structural concretes must have a set of chemical characteristics to present a satisfactory resistance to the degradation in environment conditions. Besides the several types of mineralogical compositions, the calcium-rich ...
Photoluminescence of the Eu-doped thin film heterojunction GaAs/SnO2 and rare-earth doping distribution
(Iop Publishing Ltd, 2015-01-01)
Tin dioxide (SnO2) thin films doped with Eu3+, are deposited by the sol-gel-dip-coating process on top of GaAs films, which is deposited by resistive evaporation on glass substrate. This heterojunction assembly presents ...
INFLUENCE OF HVOF COATING ON THE FATIGUE STRENGTH OF 15-5 PH STAINLESS STEEL
(Trans Tech Publications Ltd, 2014-01-01)
Structural component failures due to cyclic loading are associated to surface damage of materials and its interaction with environment. Fatigue failure occurs with stresses below the yield strength of each material and is ...
