  • Ormachea, Carla María (2018-03-16)
    The reactive behavior of a series of azaheterocyclic compounds (pyridines, pyrroles, and indoles) properly substituted has been theoretically studied, so that they can act as dienophiles in Diels-Alder processes. First, ...
  • Peltzer, Diana Jacqueline (2018-03-07)
    The aim of this thesis was to develop alkaline zirconate based materials that can react with carbon dioxide at high temperature through the carbonation reaction, allowing the CO2 capture in combustion reactions. The solids ...
  • Brites Helú, Mariela Alicia (2018-03-07)
    This work studies the synergetic interactions between PGM catalysts (Pt, Rh) and Au over both branches of the Hydrogen Electrode Reaction (HER): the Hydrogen Oxidation Reaction (hor) and the Hydrogen Evolution Reaction ...
  • Luque, Gisela Carina (2018-03-02)
    Oxidation of adsorbed carbon monoxide represents one of the biggest problems to be solved to improve the operation of low temperature fuel cells. Its presence, either as a contaminant in gaseous hydrogen of petrochemical ...
  • Papurello, Rocío Lourdes (2018-03-02)
    The objective of this Thesis is to investigate the development of films of new microporous materials that can act as means of dispersion of active phases, to be used in solid-gas catalytic reactions.Particularly, it focuses ...
  • Brussino, Paula (2018-02-23)
    Most of the artefacts that we use everyday are manufactured from ethylene. This compound production consumes great amounts of energy.Consequently, new routes for its production are being studied, i.e. the oxidative ...
  • Lanieri, Diana Beatriz (2017-04-07)
    The chemical functionalization of natural polymers constitutes a viable approach for sustainable development, being also a technologically and economically attractive alternative. At present, the viscose process continues ...
  • Nieres, Pablo Daniel (2017-03-15)
    In the present thesis, different routes for the production of valuable chemicals from oleochemical derivatives are postulated. Cross-metathesis of fatty acid esters (FAME) with alkenes is an elegant way to synthesize ...
  • Alcaraz, Mirta Raquel (2016-12-27)
    In this work, different strategies for multidimensional data generation were evaluated, and potentialities of chemometrics algorithms were explored for the analysis of complex samples. Analytical methods were developed for ...
  • Olmos, Graciela Viviana (2016-12-07)
    Cellulose is the most abundant biopolymer in the earth, however, its use is restricted by limitations derived from its structure. Since its melting point is higher than the degradation temperature, its dissolution is the ...
  • Belletti, Gustavo Daniel (2016-03-23)
    In this thesis, we theoretically study first the microscopic properties of the ferroelectric material PbTiO3 in free and ultrathin films. Using an atomistic core-shell model through classical Molecular Dynamics simulations, ...
  • López Baena, Anna Francesca (2016-03-22)
    In this work we studied a series of polar Diels-Alder reactions using different heterocycles derivatives acting as electrophiles joint to dienes of different nucleophilicity, analyzing the effect of the microwave irradiation ...
  • Castel, María Virginia (2016-03-18)
    Hydrocolloids of different origins have wide application in different industries. Among them, gum Arabic (GA) leads the world market for gums used in microencapsulation. However, their periodic scarcity and costs, drive ...
  • Sanguineti, Pamela Beatriz (2016-03-15)
    It was studied the effect of Ga2O3 (gallia) as promoter, of ZrO2 (zirconia) as support and of the Cu-Ga2O3 and Cu-ZrO2 interactions, in the catalytic performance of supported copper catalysts in the reaction of methanol ...
  • Bravo, María Virginia (2015-12-11)
    In this thesis approach a topic of particular interest in the study of ionic liquids, their physicochemical properties and molecular microscopic, as well as the binary its mixtures with molecular solvents and water. Ionic ...
  • Vanoy Villamil, Michael Nicolás (2015-03-28)
    This thesis is determined by trials for a target reaction temperature conversion of D- xylose and furfural yield at the lowest. Alumina in water at 140C, converts 80 percent of D-xylose and produced an 18 percent furfural ...
  • Fioramonti, Silvana Alejandra (2015-03-20)
    Polyunsaturated fatty acids (PUFAs) are essential nutrients that have been related with prevention of cardiovascular disease and must be incorporated in the human diet. However, as they are sensitive to lipid oxidation, ...
  • Luggren, Pablo Jorge (2015-03-11)
    In this thesis, the gas-phase conversion of 2-hexanol, a model molecule of the primary conversion of sugars, was investigated on Cu-Mı-Mıı mixed oxides (Mı, Mıı: Mg²⁺, Al³⁺, Ce⁴⁺) with different copper content (0.3-61.2 ...
  • Peralta, Guillermo Hugo (2014-07-29)
    La formación de aroma en el queso está fuertemente relacionada al catabolismo de los aminoácidos, ya que de estos derivan aproximadamente el 50% de los compuestos de aroma más importantes. Las aminotransferasas son enzimas ...
  • Manzo, Ricardo Martín (2014-06-07)
    La D-tagatosa es un azúcar raro, enantiómero de la D-fructosa, que puede obtenerse por isomerización de la D-galactosa. Su gran interés tecnológico reside no sólo en su capacidad endulzante (similar a la sacarosa) y en sus ...
