Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(The University of Bergen, 2011-05-31)
Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ...
Process Monitoring of Continuous Flow Organic Syntheses by means of Inline Fiber Optical Raman Spectroscopy
(The University of Bergen, 2010-02-08)
The objective of the current study was to investigate the feasibility of the inline optical fiber Raman spectroscopy as a tool for the process monitoring of the continuous flow organic syntheses. The synthesis of ...
Utvikling av metode for å opparbeide organisk materiale frå hydroterminalt sediment til biomarkør-analyse
(The University of Bergen, 2008-06-09)
Det første hydrotermale feltet på store havdjup vart oppdaga utanfor Galapagos i 1977. Det var forventa å finne varmekjelder også på havbotnen, men det ein ikkje forventa å finne var å finne eit rikt liv av virvellaus fauna ...
Analyse og derivatisering av fenolar i biooljer
(The University of Bergen, 2011-06-01)
Dagens samfunn er i stor grad avhengige av fossile brensel for å kunne fungere, og med fleire folkerike land i rask økonomisk vekst, er det venta at forbruket av fossile brensel vil auke ytterlegare i åra framover. Dette ...
Environmental Remediation: Removal of polycyclic aromatic hydrocarbons Dissertation
(The University of Bergen, 2012-08-17)
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous persistent semi-volatile organic compounds. They are contaminants that are resistant to degradation and can remain in the environment for long periods due to their ...
Chromatographic Fingerprinting of Chinese Grape Berries
(The University of Bergen and Central South University, China, 2014-04-14)
Chromatographic fingerprints from three varieties of grapes produced in China (Giant Rose, Red Globe and Summer Black), were obtained by gas chromatography coupled with mass spectrometry. These grapes were subjected ...
Optimization of Separation Efficiency in Temperature Programmed Gas Chromatography : Application of Response Surface Methodology
(The University of Bergen, 2014-03-14)
Chromatographic efficiency can be defined as the maximal number of chromatographic peaks that can be separated within a section of a chromatogram. In isothermal gas chromatography (GC) it is usually measured by number of ...
Synthesis and Functionalization of Periodic Mesoporous Silica
(The University of Bergen, 2008)
Different periodic mesoporous silica materials have been synthesized in order to investigate the topic of size-selective heterogeneous catalysis. SBA-1, SBA-2, SBA-16, and MCM-41 were synthesized. The cagelike SBA-1 and ...
Core photoelectron spectroscopy and chemical reactivity of a series of aliphatic alkenes and alkynes
(The University of Bergen, 2002)
Design and Synthesis of Ruthenium based Olefin Metathesis Catalysts
(The University of Bergen, 2010-06-01)
The present Master thesis seeks to develop new unsymmetrical ruthenium-based olefin metathesis catalysts and therein a better understanding of olefin metathesis catalysis with unsymmetrical active complexes. Such catalysts ...
