Synthesis and Fungicidal Activity of 2-Imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones and Their 5-Arylidene Derivatives
(Journal article; Peer reviewed, 2000)Five derivatives of 2-imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones and a series of their 5-arylidene derivatives have been synthesized and tested for antifungal activity against seven agricultural fungi. 2-Imino-3-( ... -
Heterogeneous ceramic interfaces in solid oxide fuel cells and dense oxygen permeable membranes
(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 ... -
A simple hanging mercury drop electrode
(Peer reviewed; Journal article, 2000)A device producing reproducible hanging mercury drops at the end of a glass capillary is described. Mercury flow through th capillary is controlled by means of a closing needle actuated by an electromagnetic relay. The ... -
Copper and tin incorporated microporous aluminium phosphate AIPO4-5 studied by x-ray absorption spectroscopy : including the Rietveld structure refinement of tin-containing AIPO4-5
(Doktoravhandlinger ved NTNU, 1503-8181, Doctoral thesis, 2000)X-ray absorption spectroscopy (XAS) and x-ray powder diffraction (XRD) have been used to study the metal substituted microporous aluminophoshates CuAPO-5 (Papers 1 and 2) and SnAPO-5 (Paper 3). Also investigated were the ... -
Diffusion in heterogeneous polymer systems : a nuclear magnetic resonance study
