Background Pseudotumor Cerebri (PC) is defined by an elevated intracranial pressure of unidentified cause, associated with normal cerebrospinal fluid (CSF) composition and no cause for hypertension on the neuroimaging evaluations. The symptoms descri

As-grown n-4H-SiC/SiO2 capacitors exhibit anomalous capacitance-vs.-voltage (C–V) characteristics at low temperatures. Abrupt minima appear in the C–V curves at specific values of the gate voltages independent of the sample temperature, strongly

The thixoextrusion process could become an important technique to extend the complexity of extruded profiles. However, the complex thixotropic flow behavior of semi-solid, during thixoextrusion is still partly characterized. The study described in th

In this paper, the cold simultaneous toothing of spur gears has been investigated. This method can be described as a press-rolling process. The influence of gear geometry such as teeth number and the deformation mechanism was investigated by 3D finit

In situ decomposition of silicon nitride films was observed by high-resolution electron microscopy. The films, which were produced by reactive pulsed laser deposition from Si wafer targets at 50–100 Pa ammonia pressure, had a prevalent content of h

The most important activity of wire drawing technology is the correct design of stages geometry. The wire drawing within a roller die is described by an irregular deformation on wire width, strongly connected by the gauge shape between the rollers an

We achieved the growth of cubic silicon carbide (SiC) films on (1 0 0)Si substrates by pulsed laser deposition (PLD) at moderate temperatures such as 750 °C, from a SiC target in vacuum. The as-deposited films are morphologically and structurally ch

We present a structural and morphological study on La0.6Y0.07Ca0.33MnO3−δ (LYCMO) thin films deposited by laser ablation onto MgO-buffered silicon wafers using two deposition configurations named on-axis and off-axis. All thin films have been depo

The formation of Ni silicides is studied by transmission electron microscopy during in situ heating experiments of 12 nm Ni layers on blanket silicon, or in patterned structures covered with a thin chemical oxide. It is shown that the first phase for

A microstructural investigation of porous silicon films, related with a study of carriers transport, is presented. Scanning electron microscopy and conventional transmission electron microscopy with selected area electron diffraction were performed.
