The conversion of citronellal over sulphonated polystyrene resin catalysts
Citronellal was converted over sulphonated polystyrene resin catalysts of different acid loading. The catalysts had been prepared sulphonating a commercial polystyrene resin with sulfuric acid. Catalyst activities were screened in the liquid phase and in the gas phase in a temperature range of 50 …

Multispecies reactor design for fluorination reduction of lunar regolith
Citronellal was converted over sulphonated polystyrene resin catalysts of different acid loading. The catalysts had been prepared sulphonating a commercial polystyrene resin with sulfuric acid. Catalyst activities were screened in the liquid phase and in the gas phase in a temperature range of 50 …

Mechanisms of Volatile Odorant Detection and Corresponding Behavioral Effects in Drosophila
… detect the naturally-occurring insect repellent citronellal via a mechanism involving the ion channel TRPA1. Finally, I characterized the first odorant receptor shown to be expressed in neurons of the intermediate class of olfactory sensilla, Or83c, and found that it was highly specific for a …

Dendritic rhodium catalyst precursors for the hydroformylation of olefins
… methyl oleate, triolein, D-limonene and R-citronellal. The model precursor was active in the hydroformylation of these substrates. More importantly, conversions obtained were promising for styrene (100%), D-limonene (90%), 1-octene (86%), methyl oleate (78%), 7-tetradecene (73%) and …

Tropical citrus antioxidants and catabolism of phenolics in green tea, coffee, cocoa and orange juice
… all citrus fruits and leaves was R–(+)-limonene. Citronellal was detected and was highest in C. hystrix leaf (87.8%). The radical-scavenging activity of each oil was assessed using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. Essential oils obtained from all citrus fruits showed very high …

Role of adsorption in catalysis: applications of NMR relaxometry
The work described in this thesis focuses on the effects that adsorption processes on catalytic surfaces pose in controlling key steps that can affect and control reaction pathways. To that, the development of Nuclear Magnetic Resonance (NMR) relaxometry methods and the comparison with traditional …
