    • Description of Supercritical Water-Hydrocarbon Systems 

      Kudelkova, Lucie (Dr. ingeniøravhandling, 0809-103X; 2001:53, Doctoral thesis, 2001)
      Water +n-alkane systems at high pressures and temperatures, including the critical region, have been studied and modeled. All fluids exhibit fascinating behaviour near the critical point. Thus, the thesis begins with a ...

    • Effect of surfactant structure on properties of oil/water interfaces: A coarse-grained molecular simulation study. 

      Rekvig, Live (Doktoravhandlinger ved NTNU, 1503-8181; 2004:142, Doctoral thesis, 2004)
      The elastic properties of oil/water/surfactant interfaces play an important role in the phase behaviour of microemulsions and for the stability of macroemulsions. The aim of this thesis is to obtain an understanding of ...

    • Energy efficient operation of distillation columns and a reactor applying irreversible thermodynamics 

      De Koeijer, Gelein M. (Dr. ingeniøravhandling, 0809-103X; 2002:41, Doctoral thesis, 2002)
      In this thesis the entropy production rate of diabatic distillation columns and a SO2 converter were minimised. This is the same as maximising the second law energy efficiency of the systems. The development of chemical ...

    • Equilibrium and Non-Equilibrium Thermodynamics of Natural Gas Processing 

      Solbraa, Even (Dr. ingeniøravhandling, 0809-103X; 2002:146, Doctoral thesis, 2002)
      The objective of this work has been to study equilibrium and non equilibrium situations during high pressure gas processing operations with emphasis on utilization of the high reservoir pressure. The well stream pressures ...

    • Heterogeneous ceramic interfaces in solid oxide fuel cells and dense oxygen permeable membranes 

      Faaland, Sonia (Dr. ingeniøravhandling, 0809-103X; 2000:109, Doctoral thesis, 2000)
      Solid oxide fuel cells and oxygen permeable membranes have received considerable attention during the last decade due to the increasing demand for electrical energy and easily transportable fuels combined with the requirement ...

    • Nitropyridines in Organic Synthesis. 2.5-Disubstituted Pyridine Compounds 

      Sletvold, Ingrid (Doktoravhandlinger ved NTNU, 1503-8181; 2004:34, Doctoral thesis, 2004)
      The goal of this project was to explore how 5-nitropyridine-2-sulfonic acid (18) and its potassium salt (18a) could be utilised as starting materials for 2,5- substituted pyridines. Compounds 18/18a were prepared by oxidation ...

    • Ozone based ECF bleaching of softwood kraft pulp 

      Toven, Kai (Dr. ingeniøravhandling, 0809-103X; 2000:98, Doctoral thesis, 2000)
      The objective of this work was to explore fundamental aspects of utilizing (DZ) and (ZD) bleaching stages in the prebleaching of oxygen delignified Scandinavian softwood kraft pulp, and compare paper properties of fully ...

    • Preparation and Transport Properties of SrFeO. Based Materials with controlled Microstructure 

      Glenne, Rita (Dr. ingeniøravhandling, 0809-103X; 2001:6, Doctoral thesis, 2001)
      This work consists of mainly two parts. The first part deals with the sintering behaviour and the microstructural stability of SrFe1-xCrxO3-δ, and the second with transport properties of membranes of the same compositions. ...

    • Rational design of protein inhibitors using molecular modelling and multivariate analysis 

      Tøndel, Kristin (Doktoravhandlinger ved NTNU, 1503-8181; 2004:59, Doctoral thesis, 2004)
      Cancer cells utilise signalling cascades involving protein kinases for their growth and survival. Hence, design of protein inhibitors that block the function of these signalling proteins is interesting for the development ...

    • Stereoselective Transformations of Chiral Amines 

      Said, Sadri A. (Dr. ingeniøravhandling, 0809-103X; 2002:8, Doctoral thesis, 2002)
      Enantiomerically pure amines and alcohols are particularly important synthons for the preparation of pharmaceuticals and agrochemicals. Notwithstanding the advances that have been achieved in asymmetric synthesis, resolution ...
