Solution Growth and Functional Properties of Vertically Aligned ZnO Nanowires

Fan, Jiandong (Data de defensa: 19-07-2013)
This dissertation has focused on three main topics: (1) Synthesis and characterization of ZnO:Cl NWs; (2) Hetero and homo nanostructures based on ZnO:Cl NWs for efficient PEC cells; (3) Photovoltaic performance of DSCs ...
Essays on Determinants and Effects of Barriers to Innovation

Pellegrino, Gabriele (Data de defensa: 01-12-2014)
The main aim of my doctoral thesis has been to provide new insights regarding the determinants, nature and effects of the barriers to innovation. The thesis is structured in three different but strictly related papers. ...
Hydrmagmatic monogenetic volcanism in continental and oceanic island enronments

Pedrazzi, Dario (Data de defensa: 07-03-2014)
Monogenetic volcanism is characterized by a large diversity of eruptive styles, morphologies and deposits. Monogenetic landforms are the result of a complex merging of internal (magma composition, vesiculation) and external ...
New insights into the colorectal carcinogenesis: from early precursor lesions to the role of aneuploidy

Quintanilla Leo, Isabel (Data de defensa: 20-07-2017)
Colorectal cancer (CRC) is one of the most frequent malignancies worldwide and it is considered an important healthcare problem. Moreover, colorectal carcinogenesis is a long stepwise process through a known precursor, the ...
Effects of the dipole-dipole interaction on the physics of ultracold quantum gases

Abad García, Marta (Data de defensa: 16-02-2012)
In this thesis we study the effects of the dipole-dipole interaction on the physics of ultracold quantum gases, both bosonic and fermionic, within the theoretical framework provided by the mean-field regime. This kind of ...
Sparc (Osteonectin): new insight into the function and regulation = Sparc (Osteonectin): nuevos conocimientos sobre sus funciones y regulación

Torres Núñez, Eva (Data de defensa: 21-02-2014)
The Extracellular Matrix (ECM) is a complex network secreted by cells that serves as a structural element in tissues and also influences their development and physiology. More specifically, the extracellular matrix helps ...
New strategies in metal oxide nanowire based gas sensors

Shao, Feng (Data de defensa: 31-01-2014)
This thesis presents the results of applying new strategies to understand the mechanism and explore the sensing performance of metal oxide (MOX) nanowire based gas sensors by testing individual nanowire gas sensors, running ...
Study of molecular mechanisms implicated in the TGF-beta oncogenic effect in Glioma

Gonzàlez Juncà, Alba (Data de defensa: 15-11-2013)
The TGF-beta oncogenic effect has been widely studied. In glioma, TGF-beta has an oncogenic role increasing cell proliferation and glioma-initiating cell (GIC) self-renewal capacity. During the investigation of this thesis, ...
Charipinae Worldwide Revision with special attention to Alloxysta and Phaenoglyphis genera (Hym.: Cynipoidea: Figitidae)

Ferrer Suay, Mar (Data de defensa: 05-05-2014)
Members of the subfamily Charipinae (Hymenoptera: Cynipoidea: Figitidae) are secondary parasitoids of aphids via Aphidiinae (Hymenoptera: Braconidae) and Aphelininae (Hymenoptera: Aphelinidae) and secondary parasitoids of ...
Challenges in marine ecology: genomic investigations of dispersal patterns and phenotypic plasticity in Mediterranean Fishes = Desafíos en ecología marina: investigaciones genómicas de los patrones de dispersión y de la plasticidad fenotípica en peces del Mediterráneo

Schunter, Celia (Data de defensa: 22-11-2013)
One of the most important challenges in marine ecology is understanding the dispersal capabilities of species. Connectivity, if from en evolutionary perspective or a more current ecological perspective, is highly important ...
