      Master thesis
      Restricted access - author's decision
      The esterase enzyme is in dimer form but at specific conditions it changes its structure to monomer. A study is carried out on how the enzyme performs its highest enzymatic activity and therefore provides its optimum working ...
    • Carbon dioxide laser fruit labelling 

      Jordà Soriano, Ariadna (Universitat Politècnica de Catalunya, 2020-07-15)
      Master thesis
      Restricted access - confidentiality agreement
      Covenantee:   ON-LASER Systems & Aplications
      Nowadays most of the fruits found in supermarkets have a label with the brand of the company that sells them. Most of these labels are made of non-biodegradable plastic, resulting in waste that damages the environment. ...
    • Design, implementation and test of a routine Light Sheet fluorescence microscope 

      Escobet Montalbán, Adrià (Universitat Politècnica de Catalunya, 2015-06)
      Bachelor thesis
      Open Access
      Microscopy has revealed an astonishing new world that was previously invisible to our eyes. Unfortunately, we still have very little knowledge of how life actually works, and for that reason new powerful microscopy techniques ...
    • Diffuse optics with time-pulsed, gated point and ring sources 

      Mateos Estévez, Nicolás (Universitat Politècnica de Catalunya, 2015-06-29)

    • Estudio de quelados de glicina mediante espectroscopía FTIR 

      Clemente Villalba, Jesús (Universitat Politècnica de Catalunya, 2017-09-15)
      Master thesis
      Open Access
      The objective of this work has been to elucidate the structure of metal chelates such as Fe and Zn with amino acids. To achieve this objective crystals were obtained with glycine, by two methods: precipitation and evaporation; ...
    • Inorganic solar cells based on environmentally friendly nanocrystals

      Latorre Campos, Borja (Universitat Politècnica de Catalunya, 2016-05-31)
      Master thesis (pre-Bologna period)
      Open Access
      In this work we analyze propagating LP modes (Linearly Polarized) in different independent spatial paths, mentioning the energetic density of the electromagnetic fields of these modes with a fixed normalized frequency and ...
    • MEFISTO: Caracterització de polsos làser ultracurts 

      Rodríguez Valls, Eloi (Universitat Politècnica de Catalunya, 2015-01-16)
      Master thesis (pre-Bologna period)
      Open Access
      [ANGLÈS] Due to their extremely short time duration and their high intensity, ultrashort laser pulses play an important role in many science and technology fields. In most of their applications, pulses must be characterized ...
    • Non-invasive and fast molecular imaging of biological tissues by Raman spectroscopy 

      Ruiz González, José Javier (Universitat Politècnica de Catalunya, 2019-06)
      Bachelor thesis
      60 months embargo
      Covenantee:   Institut de Ciències Fotòniques (ICFO)
      Precise clinical diagnosis of skin tumours relies on biopsy and subsequent histopathologic examination, an invasive method which represents a difficult task for clinicians to decide when to biopsy or not. For this reason, ...
    • Numerical analysis of wave propagation in hyperbolic waveguides
