Development of a compact NDIR spectometer based on MOEMS components for fruit ripening monitoring

Fonollosa Magrinyà, Jordi (Date of defense: 2009-07-20)

[spa] Actualmente el control de la concentración de etileno en las cámaras de almacenamiento de fruta proporciona información de gran interés sobre su estado. Por un lado, la fruta produce pequeñas concentraciones de etileno ...

Electron Energy Loss Spectroscopy Solutions for Nanoscale Materials Science Problems

Estradé Albiol, Sònia (Date of defense: 2009-02-21)

In the Transmission Electron Microscope (TEM), an incident electron suffers both elastic and inelastic scattering by the solid state thin sample that is being characterised. In the event of inelastic scattering, the incident ...

Smart Chemical Sensors: Concepts and Application

Udina Oliva, Sergi (Date of defense: 2012-07-13)

This PhD thesis introduces basic concepts of smart chemical sensors design, which are afterwards applied to a particular application: the analysis of natural gas. The thesis addresses thus two sets of objective, a first ...
