[spa] Esta tesis está enfocada en la búsqueda de hitos y nuevos conceptos que permitan la mejora de un producto que actualmente está dominando el mercado en su nicho de negocio español: las tuberías de PP-RCT. La empresa ...
Tahghighi, Mohammad (Date of defense: 2022-01-13)
Nanoparticle self-assembly is a versatile and coherent strategy for the development of functional nanostructured materials, offering low-cost and scalable methods that can be fine-tuned for many different specific application. ...
Cortijos i Aragonès, Albert (Date of defense: 2017-05-22)
Inspired by the proposal that single molecules will be functional elements of future nanoelectronic and Spintronics devices, there exists considerable interest in understanding charge transport in individual molecular ...
Martín Vilardell, Anna (Date of defense: 2017-01-25)
The Cold Spray (CS) is a novelty technique for the production of coatings within the field of Thermal Spray. The use of low work temperatures (under the melting point of the material) is what makes it different from the ...
Posada Pérez, Sergio (Date of defense: 2018-03-12)
Our society has a problem with the use of fossil fuels, due to the vast and exceeding emissions derived from human activities. Two ways could be consider to mitigate these harmful effects. On the one hand, the capture, ...
Escobar Romero, Ana Maria (Date of defense: 2018-12-09)
La modificació de les superfícies dels materials permet obtenir propietats diferents a les que presenta el substrat prèviament o preservar-lo del medi que l’envolta. Les tècniques emprades amb aquest objectiu són molt ...
Regordosa Romagosa, Anna (Date of defense: 2017-05-03)

Ozaeta Laverde, Pablo (Date of defense: 2017-07-12)
Natural Gas with more than 80% methane has a liquefaction temperature around -165 ° C. Temperature at which the gas reduces its volume by a factor of 600/1. This operating temperature makes the use of ferritic materials ...
Cuko, Andy (Date of defense: 2018-09-24)
Properties of nanomaterials are known to be size dependent and generally are very different from those of the corresponding bulk. Such behaviour, which is strongly system and structure dependent, allows one to tune material’s ...
Alonso Benito, Gerard (Date of defense: 2019-11-29)
Two main topics are treated in this doctoral thesis from a theoretical and computational point of view: the gas capture and separation from post-combustion flue gases, and the enhanced oil recovery from oil reservoirs. The ...
