    Controlling mechanism in the aqueous absorption of nitrogen oxides (1955)

    Notes: The reactions involved in the removal of nitrogen oxides from gases by reaction with water are reversible and proceed at a finite rate. It is possible therefore that the over-all process is controlled by the rate of the chemical reactions. On this basis an analysis of the process has been developed by the application of chemical kinetics, with consideration of reactions involving both nitrogen dioxide and dinitrogen tetroxide. The resulting differential equation has been simplified and integrated to give a final equation which can be tested experimentally.Theoretical methods are presented for predicting the extent of absorption of nitrogen oxides at various gas rates and concentrations and are compared with the experimental results.The paper presents some new concepts of the factors which control the rate of absorption of nitrogen dioxide and dinitrogen tetroxide in water. An understanding of the controlling factors in the process should indicate methods for improving the design of absorption towers in nitric acid plants and aid in the design of scrubbers for removing nitrogen oxides from waste gases.

    Simulation of particulate removal in gas-solid fluidized beds (1982)
    Hoboken, NJ : Wiley-Blackwell

    Notes: A mathematical model for simulating particulate removal in gas-solid fluidized beds is developed based on bubble assemblage concepts and particulate collection mechanisms. The importance of fluidization mechanics on the overall fluidized bed filtration performance is emphasized in the present study. Model predictions of fluidized bed filtration efficiencies are shown to compare favorably to the experimental results of various investigations. Because of the general formulation of the proposed model, it is believed to be applicable in the design of fluidized bed filtration operations.

    Notes: Abstract Estimation of the source of activity in the brain from electro- and magneto-encephalographic measurements is becoming increasingly common. Structural information could assist in improving the calculation of the sources as well as providing the context of the source location. Magnetic resonance images are very useful for this purpose, but they still need to undergo various processing steps. The paper describes in details a practical method for full automatic processing of MRI images of a head, including segmentation of the images and triangulation of the surfaces.

    Notes: Die Bedeutung der verschiedenen Arten der Stickoxide und ihr Beitrag zur Luftverunreinigung wird analysiert. Als Stickoxid-Quellen sind in dieser Hinsicht Kraftfahrzeuge von besonderer Bedeutung. Bei der Analyse der Methoden zur Verringerung des Stickoxid-Gehaltes von Abgasen wird der Entstehung von Stickstoff-Verbindungen in Verbrennungsmotoren und ihrer Verringerung durch direkte katalytische Reduktion besondere Aufmerksamkeit geschenkt. Zukünftig notwendige Forschungs- und Entwicklungsvorhaben werden behandelt, wobei neue, die Luft nicht verschmutzende Transportmittel für den Massenverkehr in die Betrachtungen mit einbezogen werden.

    Description / Table of Contents: Crystal and Molecular Structure of SbI3 · 9S3 (9S3 = 1.4.7-Trithiacyclononane).SbI3 forms a 1:1 adduct with 1.4.7-trithiacyclononane. The crystal structure exhibits discrete complexes with a distorted octahedral coordination of antimony(III). In comparison with molecular SbI3 the Sb—I distances are elongated from 271.9 to 290.4 pm (mean). The mean value of the Sb—S distances is 287.5 pm. The planes through iodine and sulfur atoms, respectively, are nearly coplanar. There is no significant stereochemical influence of the Sb(III) lone pair.
    Notes: SbI3 bildet ein 1:1-Addukt mit 1,4,7-Trithiacyclononan. Die Kristallstruktur enthält diskrete Komplexe mit verzerrt oktaedrischer Koordination von Antimon(III). Im Vergleich zum molekularen SbI3 ist der Sb—I-Abstand von 271,9 auf 290,4 pm aufgeweitet. Der mittlere Sb—S-Abstand beträgt 287,5 pm. Die Ebenen durch die drei Iod- und drei Schwefelatome sind nahezu koplanar. Ein signifikanter stereochemischer Einfluß des nichtbindenden Elektronenpaares von Sb(III) ist nicht zu erkennen.

    Description / Table of Contents: Neutral Thiolates and a Iodothiolate of Antimony(III). Crystal Structures of Sb(SC6H5)3, Sb(SC6H2Me3-2,4,6)3, and SbI(SC6H2Me3-2,4,6)2The crystal structures of Sb(SC6H5)3 (1), Sb(SC6 · H2Me3-2,4,6)3 (2), and the novel compound SbI(SC6H2Me3-2,4,6)2 (3) have been determined by X-ray crystallography. In addition to the expected trigonal pyramidal coordination of antimony intermolecular interactions are observed for 1 (Sb … O: 363.3 pm) and 3 (Sb … S: 2 × 369.4 pm) but not for 2. The reasons for these differences are discussed.
    Notes: Die Kristallstrukturen von Sb(SC6H5)3 (1), Sb(SC6H2Me3-2,4,6)3 (2) sowie der neuen Verbindung SbI(SC6H2Me3-2,4,6)2 (3) wurden mit Hilfe von Röntgenbeugungsmethoden bestimmt. Zusätzlich zu der erwarteten trigonal pyramidalen Umgebung von Antimon werden für 1 und 3, nicht jedoch für 2, intermolekulare Wechselwirkungen beobachtet (1: Sb … C: 363,3 pm; 3: Sb … S: 2 × 369,4 pm). Die Ursachen für diese Unterschiede werden diskutiert.
