Degradation of metoprolol by means of advanced oxidation processes

Romero Olarte, Rossmary Violette (Date of defense: 2015-05-20)

For this study the emerging contaminant ß-blocker Metoprolol (MET) has been selected due that it is a highly prescribed pharmaceutical and it has been detected in waste water treatment plants influents, thus, in natural ...

Design, characterization and applications of polyester nanoparticles obtained by enzymatic polymerization in nano-emulsions prepared by low-energy methods

Paulme, Camille (Date of defense: 2013-02-01)

The presence of volatile fragrant molecules is generally associated with a feeling of pleasantness or cleanness in consumer products. Because of their high volatilities, the perception of fragrances is limited over time. ...

Estudio de la eliminación de contaminantes emergentes en aguas mediante Procesos de Oxidación Avanzados

Cruz González, Natalia de la (Date of defense: 2013-11-14)

Este trabajo se ha centrado en la degradación de contaminantes emergentes mediante POAs, adelantándose a una posible legislación futura en este campo. En esta línea, el trabajo se enfocó en tres grandes bloques: ▪ Se ...

Estudio de la preparación, viabilidad industrial y aplicación de los materiales porosos de sílica

Santamaría Hernández, Esther (Date of defense: 2014-01-16)

Desde que en la década de los 90 se sintetizó el primer material mesoporoso ordenado se han estudiado diferentes rutas de síntesis con el objetivo de poder obtener materiales con los tamaños de poro y estructuras deseadas. ...

Ethyl octyl ether synthesis from 1-octanol and ethanol or diethyl carbonate on acidic ion-exchange resins

Guilera Sala, Jordi (Date of defense: 2013-07-19)

Ethyl octyl ether is a bioethanol-derived component that has excellent properties as diesel fuel. This work proved that ethyl octyl ether can be produced successfully in liquid-phase at the temperature range of 130-190ºC ...

Inorganic nanoparticles synthesized by the novel oil-in-water microemulsion reaction method and their potential applications

Pemartin, Kelly Lidia (Date of defense: 2013-01-31)

The use of microemulsions as confined reaction media for nanoparticle synthesis presents various advantages compared to other methods. They offer a high control of nanoparticle size and often nanoparticles with crystalline ...

Insights into nanomaterials: from surfactant systems to meso/macroporous materials and nanoparticles

May Masnou, Anna (Date of defense: 2014-06-13)

Nanomaterials have structured components with at least one dimension of less than 100 nm. Their novel properties stem from their nanoscale dimensions and increased relative surface area, and they have a wide range of ...

Liquid Phase Dehydration of 1-Butanol to Di-n-butyl ether Experimental Performance, Modeling and Simulation of Ion Exchange Resins as Catalysts

Pérez-Maciá, María Ángeles (Date of defense: 2015-11-27)

Di-n-butyl ether (DNBE) is considered a very attractive oxygenate compound to reformulate diesel fuel. The research work performed along this thesis has clearly proven that sulfonic P(S-DVB) ion exchange resins are suitable ...
