The development of new technologies, active ingredients and regulatory initiatives, has increased the need for a scientific understanding of the pharmaceutical manufacturing processes. In this context, solid dosage forms ...
Selective hydrodeoxygenation of biomass-derived oxygenates over heterogeneous Mo-based catalysts
(2021-07)
The development of catalytic pathways to produce commodity chemicals from lignocellulosic biomass is promising for substituting non-renewable fossil feedstock use. This dissertation studied the catalytic performance of ...
In situ diffraction studies of Ni nanostructure growth using microporous materials as supports
(2009)
Our objective is to study the growth mechanism of Ni nanostructures supported in microporous materials using X-ray diffraction. Since only the surface atoms of a catalyst are active, our aim is to find the optimum synthesis ...
Analysis of reaction pathways on the catalytic conversion of CO2 using quantum mechanical calculations
(2015)
The greenhouse gas CO2 is an inexpensive and abundant feedstock that may be used to produce valuable organic compounds. The main goal of this work was to unravel reaction pathways for CO2 conversion through hydrogenation ...
Transport properties of proton-exchange membranes: effect of supercritical-fluid processing and chemical functionality
(2010)
Nafion® membranes commonly used in direct methanol fuel cells (DMFC), are tipically limited by high methanol permeability (also known as the cross-over limitation). These membranes have phase segregated sulfonated ionic ...
