This work presents the characterization of birefringent properties of titanium-oxide thin films using spectrophotometry and double-cavity Fabry-Perot structures. All films were deposited by DC sputtering over tilted substrates and the birefringence w

A reversible memory behavior in TeO 2 –ZnO thin films containing Au nanoparticles prepared using the sputtering technique has been observed. The current–voltage characteristics of the films, having Al and Si as electrodes, showed a switching beha

Macroporous silicon (MPS) films were yielded by electrochemical anodization of p-type crystalline silicon in HF:DMF. Following, a Schottky structure was obtained by depositing polyaniline (PANI), which was doped with different contents of erbium (Er)

This work discusses the detection of ionization current for Homogeneous Charge Compression Ignition (HCCI) on dual mode engines using a compact and versatile flyback circuit. Since spark plugs come already incorporated in the engines, they are common

This work presents the obtainment of porous silicon films by a continuous etch at a constant current density (j = 150 mA/cm2, tetch = 180 s) and a stop-etch method employing j = 150 mA/cm2 for ton = 2 s and j = 0 mA/cm2 for toff = 10 s. It was notewo

This work proposes a new geometry for an Ion Mobility Spectrometer (IMS) in order to detect toluene, 2-propanol and water vapor. The IMS system was designed with a compact ionization chamber followed by another capable of selectively discriminate the
