CPT1C in the ventromedial nucleus of the hypothalamus is necessary for brown fat thermogenesis activation in obesity

R. Rodríguez-Rodríguez, C. Miralpeix, A. Fosch, M. Pozo, M. Calderón-Domínguez, X. Perpinyà, M. Vellvehí, M. López, L. Herrero, D. Serra and N. Casals. Molecular Metabolism Link DOI: doi.org/10.1016/j.molmet.2018.10.010 Objective: Carnitine palmitoyltransferase 1C (CPT1C) is implicated in central regulation of energy homeostasis. Our aim was to investigate whether CPT1C in the ventromedial...

Advanced processing for mobility improvement in 4H-SiC MOSFETs: A review

M. Cabello, V. Soler, G. Rius, J. Montserrat, J. Rebollo and P. Godignon Materials Science in Semiconductor Processing (2017) This paper reviews advanced gate dielectric processes for SiC MOSFETs. The poor quality of the SiO2/SiC interface severely limits the value of the channel field-effect mobility, especially in 4H-SiC MOSFETs. Several strategies have been addressed...

Short-Circuit Study of Medium Voltage GaN Cascodes,
P-GaN HEMTs and MISHEMTs

M. Fernández, X. Perpiñá, J. Roig, M. Vellveh, F. Bauwens, M. tack and X. Jordà. IEEE Transactions on Industrial Electronics, 64 (11), pp. 9012-9022 (2017) This paper studies by experimentation and physics-based simulation the Short-Circuit (SC) capability of several normally-off 600-650 V Gallium Nitride High-Electron-Mobility Transistors (GaN HEMTs): cascodes, p-GaN,...

Thermal phase lag heterodyne infrared imaging for current tracking in radio frequency integrated circuits

X. Perpiñà, J. León, J. Altet, M. Vellvehi, F. Reverter, E. Barajas, and X. Jordà Applied Physic Letters, 110, 094101 (2017) With thermal phase lag measurements, current paths are tracked in a Class A radio frequency (RF) power amplifier at 2 GHz. The amplifier is heterodynally driven at 440MHz and 2 GHz,...
