Chemical Insights from Carbon 1s Photoelectron Spectroscopy and Theoretical Modeling
(The University of Bergen, 2007-08-31)
Inner-shell ionization energies provide local probes of the charge distribution in molecules and of the ability of a molecule to accept charge at specific sites. As such, core-ionization energies are related to and may ...
Konsekvensutredning av akvakultur. - en studie av KU prosessen for Ryfylke bassenget i 2005
(The University of Bergen, 2009)
Synthesis of Some Nitrogen Heterocycles of Medicinal Relevance
(The University of Bergen, 2012-04-18)
In the first part of the project, two highly functionalized terminal alkynes, 3,3,4,4- tetraethoxybut-1-yne (TEB) and 1,1-diethoxy-but-3-yn-2-one (keto-TEB) have been used for the synthesis of 1,4-disubstituted ...
Enhanced Oil Recovery by Combined Low Salinity Water and Polymer Flooding
(The University of Bergen, 2014-06-19)
<p>World energy demand is continuously increasing as the developed and developing countries consume more energy to keep their growing industries running. Significant portion of the energy demand is supplied by fossil ...
Revealing the secrets of proteins: A triple-nuclear and multi-dimensional high-resolution NMR spectroscopy study
(The University of Bergen, 2012-08-28)
<p>Nuclear magnetic resonance (NMR) spectroscopy is one of the major tools for studying the structure and dynamics of proteins in solution. The still ongoing development of new and improved pulse-sequences for ...
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 ...
Origin and character of gaseous hydrocarbons in the hydrate and non-hydrate charged sediments on the Norway - Svalbard margins
(The University of Bergen, 2011-05-26)
Gas incubated in clathrate water-structures, stabilizes the hydrogen bonded substance termed gas hydrate. In the marine environment vast amount of carbon is stored as gas hydrates within the temperature and pressure ...
Physico-Chemistry Characterization of Sulfonated Polyacrylamide Polymers for Use in Polymer Flooding
(The University of Bergen, 2010-06-01)
Hydrolyzed polyacrylamide polymer (HPAM) as a feasible and effective viscosifier has been fully studied and used for polymer flooding processes in several oil field, e.g. Daqing oil field. It has been shown that Hydrolyzed ...
Crude oil components with affinity for gas hydrates in petroleum production
(The University of Bergen, 2007-06-28)
Some crude oils are believed to contain natural inhibiting components that can prevent hydrate plugging of oil pipelines in petroleum production. A method for classification of the oils that form hydrate plugs, as opposed ...
Static and dynamic studies of foam and foam-oil interactions
(The University of Bergen, 2006-11-03)
