Treball Final de Grau
Accés restringit per decisió de l'autorTranscranial current stimulation (tCS) is a non-invasive brain stimulation technique based on the application of weak electrical currents in the scalp (ă 4 mA) at low frequencies (0-1 kHz). ... -
Sistema experimental para la medición de la temperatura durante el Flash Sintering de muestras policristalinas
(Universitat Politècnica de Catalunya, 2021-01)
Treball Final de Grau
Accés obertFlash Sintering (FS) is a new sintering technique for ceramic materials that considerably reduces the time and costs of current sintering processes. The difference with conventional sintering is the application of electrical ... -
Sublinear dispersive conductivity in polyetherimides by the electric modulus formalism
(2015-12)
Article
Accés obertTwo commercially available polyetherimides, Ultem 1000 and Ultem 5000, have been studied by means of Dynamic Electrical Analysis. Results show that at temperatures above the glass transition dielectric response is highly ... -
THz time-domain spectroscopy and IR spectroscopy on MoS2
(2016-12-09)
Article
Accés obertIn the increasing research field of 2D materials such as graphene, molybdenum disulfide MoS2 has attracted great interest due to the existence of a direct bandgap in monolayer MoS2, which gives the possibility of achieving ... -
Viscous regime of electron transport at a graphene constriction
(Universitat Politècnica de Catalunya, 2017-04)
Treball Final de Grau
Accés obert
Realitzat a/amb: Massachusetts Institute of TechnologyUnder mesoscopic conditions, strong electron-electron interactions and weak electron-phonon coupling in graphene lead to an hydrodynamic behaviour of electron dynamics, resulting in unusual transport phenomena. During the ...
