Pastorelli, Francesco (Data de defensa: 2013-12-09)
In this century some of our main issues are energy shortage and pollution. This work will briefly describe these problems, proposing a plan of action combining energy saving and different sustainable ...
Maigyte, Lina (Data de defensa: 2014-07-01)
The research developed in the framework of this PhD thesis is a theoretical, numerical and experimental study of light beam shaping (spatial filtering, beam collimation and focusing) in the visible ...
Vidas, Luciana (Data de defensa: 2019-05-02)
The physics of transition-metal oxides presents a challenge to our current understanding of condensed matter physics. The main difficulty arises from a competition between electron-electron and ...
Gieseler, Jan (Data de defensa: 2014-02-03)
Nanotechnology was named one of the key enabling technologies by the European Commission and its tremendous impact was envisioned early by 20th century physicist R.Feynman in his now oft-quoted talk ...
Hernández García, David (Data de defensa: 2014-10-23)
Un dels límits fonamentals que afecta l'eficiència de conversió en cèl·lules fotovoltaiques és la distribució espectral de la radiació solar. D'una banda, només els fotons amb energia superior al gap ...
Hauke, Philipp Hans-Jürgen (Data de defensa: 2013-04-05)
Many outstanding problems in quantum physics, such as high-Tc superconductivity or quark confinement, are still - after decades of research - awaiting commonly accepted explanations. One reason is that ...
Farzam, Parisa (Data de defensa: 2014-10-14)
Noninvasive measurement of hemodynamics at the microvascular level may have a great impact on oncology in clinics for diagnosis, therapy planning and monitoring, and, in preclinical studies. To this ...
Yao, Can (Data de defensa: 2014-06-25)
Disordered media with refractive index variations can be found in the atmosphere, the ocean, and in many materials or biological tissues. Several technologies that make use of such random media, as image ...
Muñoz Porcar, Constantino (Data de defensa: 2013-02-22)
This thesis is the initial stage in the development of a range-resolving Doppler wind lidar. Atmospheric lidars emit pulsed laser radiation that after being scattered by air molecules and suspended ...
Grün, Alexander (Data de defensa: 2014-11-07)
In this thesis I investigate two methods for generating ultrashort laser pulses in spectral regions which are ordinarily difficult to achieve by the existing techniques. These pulses are specially ...
