Treatments and Analysis of C-sp(2) nanomaterials

Claramunt Ruiz, Sergi (Date of defense: 2014-02-10)

Carbon can be found or synthesised in different arrangements, each one with its particular properties. Curiously, the main building block of the majority of these structures (graphene) was first isolated in 2004 by A.K ...

Tungsten oxide nanocrystalline powders for gas sensing applications

Jiménez Gallardo, Ismael (Date of defense: 2003-09-08)

This doctoral dissertation deals with the study of nanocrystalline tungsten oxide-based powders for gas sensing applications. Gas monitoring is receiving increasing attention due to environmental and safety reasons. Gas ...

Understanding the role of sensor diversity and redundancy to encode for chemical information in gas sensor arrays

Fernández Romero, Luis (Date of defense: 2016-01-25)

Electronic noses (e-noses) have been utilized during the past three decades as general purpose instruments for chemical sensing. These instruments are inspired by natural olfactory systems, where fine odour discrimination ...

Vibrational properties of ZnO, group III-nitrides and dilute nitride alloys

[spa] Esta tesis consiste en el estudio de las propiedades vibracionales de materiales de interés para la fabricación de dispositivos optoelectrónicos, operando en distintos rangos espectrales, desde ultravioleta hasta el ...

Wideband pulse amplifiers for the integrated cameras of the Cherenkov Telescope Array

Sanuy Charles, Andreu (Date of defense: 2016-02-04)

One type of photon detector is the photomultiplier tube (or PMT), most commonly used in Imaging Atmospheric Cherenkov Telescopes (IACTs). A PMT has a photoelectric cathode that absorbs light and emits an electron. A PMT ...
