How does the knowledge of Swiss consumers on palm oil affects consumption patterns?

Abbondioli, Estelle ; Depetris Chauvin, Nicolas (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2018 ; TDIBM 29.

Palm oil is the most produced vegetable oil and accounts for 30% of the global vegetable oil production. This significant production generates negative externalities such as contributing to climate change, deforestation of the rainforests and biodiversity loss. However, this vegetable oil holds many advantages as well, such as having the highest agricultural yield, creating jobs and wealth for...

Controlling the supramolecular assembly of perfluorinated polycondensed aromatic hydrocarbons by side chain engineering

Aebischer, Olivier F. ; Jenny, Titus (Dir.) ; Weiss, Antoine (Codir.)

Thèse de doctorat : Université de Fribourg, 2007 ; Nr. 1575.

Nanotechnologie ist ein Begriff, dessen Bedeutung ständig wächst, da die Industrie täglich mehr Materialien auf den Markt bringt, welche im Prozess der Miniaturisierung bis in den Nanometerbereich entwickelt wurden. Vom heutigen Standpunkt aus ist es längst nicht mehr klar, wohin uns die Nanotechnologie noch führen wird. Kann der Traum von molekularen Maschinen, die mit „atomarer“...

Synthesis and investigation of new large self-assembled supramolecules as potential electron emitters

Alameddine, Bassam ; Jenny, Titus (Dir.)

Thèse de doctorat : Université de Fribourg, 2004 ; no 1440.

Nanotechnology, a research area that covers many scientific disciplines such as Medicine, Biology, Physics and Chemistry has found a great interest in research institutions and wide applications in industries. This is due to many reasons; from these we note the control down to the molecular level providing thereby a greatest efficiency and an important added value as a reason of the low cost of...

Controlling the lateral aggregation of perfluoroalkylated hexa-peri-hexabenzocoronenes

Aebischer, Olivier F. ; Aebischer, Annina ; Donnio, Bertrand ; Alameddine, Bassam ; Dadras, Massoud ; Güdel, Hans-Ulrich ; Guillon, Daniel ; Jenny, Titus A.

The investigation of two hexa-peri-hexabenzocoronene (HBC) derivatives carrying linear or branched perfluoroalkylated side chains is reported. Polycondensed aromatic hydrocarbons (PAH) such as HBC derivatives are well known to self-organize to form highly ordered monomolecular stacks, which in turn show a concentration- and solvent-dependent lateral aggregation. However, possible...

Synthesis and application of an electronically chiral mimic of CpFe

Allemann, Christophe ; Jenny, Titus (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; No 1369.

The field of new optically active and reactive organometallic species is of tremendous interest. Within this area, (-)-(1S)-dicarbonyliodide[μ5-(2,8,8-tri-methylbicyclo[3.2.1]oct-3,6-diene)2-yl] iron (1), called 2-Me-BOD-Fe(CO)2I, emerges as a new stage in the development of chiral cyclopentadienyl-like complexes. Studying the reactivity of 1 has shown that both its non-contiguous μ5-system and...
