Undersøkelse over "konkurrerende vekst" ved seed-polymerisasjon av vinylklorid
(Master thesis, 1970)Det ble i dette arbeidet studert den relative veksten av to partikkelstørrelser ved emulsjonspolymerisasjon av vinylklorid (seedpolymerisasjon). Det ble benyttet partikler med diametere omkring 1000 og 2000 Å. Det totale ... -
Reduction Factor for Polyaniline Films on ITO from Cyclic Voltammetry and Visible Absorption Spectra
(Journal article; Peer reviewed, 1993)The reduction factor as a function of applied potential for polyaniline films, deposited electrochemically on indium—tin oxide glass plates, has been determined from cyclic voltammetry and from visible absorption spectra, ... -
Materialstrømanalyse for aluminium i Norge
(Master thesis, 1998)Oppgavens hovedformål har vært å kartlegge materialflyten av aluminium i Norge. Hensikten med en slik kartlegging var å drøfte dagens og fremtidens resirkuleringsgrad i relasjon til teknologisk løsning og økologisk ... -
Electrochemical multilayer deposition of polyaniline and Prussian Blue and their application in solid state electrochromic windows
(Journal article; Peer reviewed, 1998)In an attempt to enhance the solar modulation in electrochromic windows, the electrochemical deposition of polyaniline (PANI) and prussian blue (PB been studied more closely. Several layers of PANI and PB at different ... -
Separation of azeotropic mixtures : tools for analysis and studies on batch distillation operation
(Dr.ingeniøravhandling, 0809-103X; 2000:115, Doctoral thesis, 2000)Separation of azeotropic mixtures is a topic of great practical and industrial interest. Most liquid mixtures of organic components form nonideal systems. The presence of some specific groups, particularly polar groups ... -
Phase equilibria in polyethylene systems
(Dr.ingeniøravhandling, 0809-103; 2000:47, Doctoral thesis, 2000)The background for this work is a need to better understand the production of high density polythylene (HDPE). HDPE particles grow in a loop slurry reactor, and particle swelling and slurry viscosity are critical parts in ... -
