Efeitos do autoaquecimento em transistores SOI-MOS tridimensionais nanométricos
(Centro Universitário FEI, São Bernardo do Campo, 2016)
O autoaquecimento é um efeito que os dispositivos SOI MOSFETs estão sujeitos, quando a potência dissipada na forma de calor encontra dificuldade em dissipar-se para fora do dispositivo. Este efeito é muito comum e ocorre ...
Effective action for delta potentials: Spacetime-dependent inhomogeneities and Casimir self-energy
(American Physical Society, 2021-03)
We study the vacuum fluctuations of a quantum scalar field in the presence of a thin and inhomogeneous flat mirror, modeled with a delta potential. Using heat-kernel techniques, we evaluate the Euclidean effective action ...
Photothermal triggering of self-healing processes applied to the reparation of bio-based polymer networks
(IOP Publishing, 2016-04-01)
Green laser irradiation successfully activated self-healing processes in epoxy-acid networks modified with low amounts of gold nanoparticles (NPs). A bio-based polymer matrix, obtained by crosslinking epoxidized soybean ...
Acoustic Emission behavior of thermally damaged Self-Compacting High Strength Fiber Reinforced Concrete
(Elsevier, 2018-10)
This paper investigates the effect of high temperature on two different Self-Compacting (SC) cementitious composites. SC-High Strength (SCHSC) and Fiber-Reinforced Concrete (SCHSFRC) samples were tested in three-point ...
Assessment of the sustainability of asphalt pavement maintenance using the microwave heating self-healing technique
(ELSEVIER SCI LTD, 2022)
Pavements are the major load-carrying Civil Engineering structures in roads, runways, parking lots, and driveways; hence, they are fundamental for regional or national development. However, the pavement life cycle has ...
Experimental and numerical analysis on the formability of a heat treated AA1100 aluminum alloy sheet
(Springer, 2015-03)
The objective of this work is to experimentally and numerically determine the influence of plastic anisotropy on the forming limit curve (FLC) for a heat-treated (300 C-1 h) AA1100 aluminum alloy sheet. The FLCs were ...
Alternative high plasma beta regimes of electron heat-flux instabilities in the solar wind
(IOP Publishing, 2020)
Heat transport in the solar wind is dominated by suprathermal electron populations, i.e., a tenuous halo and a field-aligned beam/strahl, with high energies and antisunward drifts along the magnetic field. Their evolution ...
Estudo do efeito de autoaquecimento em transistores com canal por medida pulsada
(Centro Universitário da FEI, São Bernardo do Campo, 2012)
A tecnologia do transistor MOS com Silício sobre Isolante (SOI) tem aberto oportunidade para inovação, aumento de desempenho e redução do tamanho do dispositivo, que a
tecnologia CMOS "bulk" tem dificuldade para alcançará. ...
