71.	Ackelid, Ulf, et al. (author) Ethanol sensitivity of palladium-gate metal-oxide-semiconductor structures 1986 In: IEEE Electron Device Letters. - : Institute of Electrical and Electronics Engineers (IEEE). - 0741-3106 .- 1558-0563. ; 7:6, s. 353-355 Journal article (peer-reviewed)abstract Hydrogen-sensitive palladium-gate MOS structures heated above 150°C show sensitivity to ethanol vapor. The effect is probably due to catalytic dehydrogenation of adsorbed ethanol molecules on the surface of the palladium gate.
72.	Ackeskog, Hans, et al. (author) An investigation of fluidized-bed scaling: heat transfer measurements in a pressurized fluidized-bed combustor and a cold model bed 1993 In: Chemical Engineering Science. - 0009-2509. ; 48:8, s. 1459-1473 Journal article (peer-reviewed)abstract A method is proposed for predicting heat transfer coefficients in hot fluidized-bed combustors by translating results measured in a scaled-down, cold model bed. Provided the beds are scaled to hydrodynamic similarity, local heat transfer coefficients measured in the cold model bed can be translated into local hot-bed convective coefficients with the aid of existing correlations for the gas and particle convective components. To obtain the total hot-bed-to-surface coefficients, a radiative component is then added. The chief advantages of the proposed method are that existing convective heat transfer correlations can be applied locally in a bed, and that no a priori knowledge of the voidage close to the transfer surface is required. In a previous paper by Almstedt and Zakkay, measurements of the bubble activity in a pressurized fluidized-bed burning coal and in a scaled-down pressurized model bed operating at room temperature showed that a good hydrodynamic similarity can be obtained between the beds. The heat transfer translation method proposed here has been validated by comparing heat transfer coefficients measured in the same two beds, operating under scaled conditions. Average heat transfer coefficients for four different horizontal tube bundles, as well as local coefficients measured with probes in four different positions were compared. The results indicate good agreement between the hot-bed results measured and the results translated from the model bed measurements employing the proposed method. Furthermore, the present paper presents heat transfer measurements from the cold model bed for three different bed materials, at pressures of 0.1, 0.24 and 0.5 MPa and fluidization velocities ranging from 0.15 to 1.3 m/s. The results are in good accordance with existing theory, but indicate that the gas convective component (as well as the particle convective component) is significantly dependent on the fluidization velocity.
73.	Adal, M, et al. (author) Determination of monomer reactivity ratios in the copolymerization of ethylene oxide and propylene oxide 1994 In: Tenside Surfactants Detergents. - 0932-3414 .- 2195-8564. ; 31, s. 9-11 Journal article (peer-reviewed)abstract The reactivity ratios r1 (EO) and r2 (PO) for the copolymerization of ethylene oxide (EO) and propylene oxide (PO) have been determined. The reactions were carried out in dry dimethyl formamide at 90°C using the potassium salt of ethylene glycol as initiator. The polymer composition at different EO/PO ratios in the feed was determined by 1H-NMR. Using the Fineman-Ross method to calculate reactivity ratios from the values of polymer composition, rl- and r2-values of 1.8 and 0.3, respectively, were obtained.
