Improved binary and ternary nanostructured photocatalysts for gas phase detoxification of toluene
(2005)
Photocatalysis using nanocrystalline materials with enhanced catalytic properties under ultraviolet (UV) or visible light has the potential for becoming one of the leading processes for the abatement of environmental ...
Effect of operational and design parameters on the early stages of high shear wet granulation processes
(2014)
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 ...
Development of optimized therapeutic platforms for magnetic fluid hyperthermia in adjuvant cancer therapies
(2018-05)
Magnetic Fluid Hyperthermia (MFH) has a great potential as an adjuvant in cancer therapy, enhancing the
effects of antineoplastic agents, sensitizing resistant cancers and reducing undesired side effects. When
compared ...
Reverse micelles in supercritical carbon dioxide for pharmacological applications: a spectroscopic characterization
(2004)
The aim of this research is to characterize microemulsions in supercritical (sc) CO2 using two spectroscopic techniques (UV-Vis and FT-IR) and apply the microemulsion approach to extract impurities from a pharmacological ...
Novel sulfonated ether based block copolymer ionomers as proton exchange membranes for fuel cells applications
(2017)
This investigation studied the morphology, hydration, and transport properties of different membranes for direct methanol fuel cell (DMFC) applications. First, sulfonated poly(ether ether ketone) (SPEEK) membranes were ...
Surface modification of nanoporous films using organosilanes dissolved in supercritical carbon dioxide
(2008)
It is well known in the microprocessor industry that as the number of transistors increases, the capacity of chips to manage information also increases. To continue with the increment in the number of transistors per ...
