    NO monomer and (NO)x polymeric chain chemisorption on Pt{110}: Structure and energetics (1999)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 110 (1999), S. 12082-12088 
    Details
    ISSN: 1089-7690
    Source: AIP Digital Archive
    Topics: Physics , Chemistry and Pharmacology
    Notes: The chemisorption of NO on Pt{110}-(1×1) and -(1×2) has been studied using density functional theory slab calculations with the generalized gradient corrections. On both surface phases the monomeric species is the most stable and the short-bridge sites are energetically the most favorable adsorption sites. Monomeric NO is adsorbed upright with its molecular axis normal, bonded to the surface through the N atom. On the (1×2) surface at high coverage a polymeric (NO)x chain structure is identified; this may well correspond to the structure experimentally observed at high coverage on the (1×2) surface formed after heating a multilayer to temperatures between 80 K and 200 K, characterized by an NO IR band at 1760 cm−1. © 1999 American Institute of Physics.

    Grafting onto wool (1981)
    Springer
    Polymer bulletin 4 (1981), S. 635-640 
    Details
    ISSN: 1436-2449

    Notes: Summary In order to study the role of -SH group of wool in graft copolymerization, an attempt has been made to study grafting of acrylic acid (AAc) onto reduced wool in aqueous medium using ceric ammonium nitrate (CAN) as redox initiator. HNO3 was found to catalyze the graft copolymerization. Reduction of wool was effected with thioglycolic acid (TGA) in aqueous medium. Percentage of grafting was determined as a function of concentration of (i) CAN, (ii) vinyl monomer (AAc), (iii) nitric acid, (iv) time and (v) temperature. Under optimum conditions, poly-(acrylic acid) was grafted to the reduced wool to the extent of 9.14%, the unreduced wool under optimum conditions afforded maximum grafting of poly(AAc) to the extent of 12.24%. Reduction of wool does not promote grafting of AAc in the presence of CAN.

    Stabilities of some bivalent transition metal ions with 2-hydroxy naphthaldehyde semicarbazones and thiosemicarbazones in dioxane-water mixtures: A potentiometric study (1992)

    Description / Table of Contents: Zusammenfassung Es wurden die Gleichgewichte zwischen 2-Hydroxynaphthaldehyd-Semicarbazonen und -Thiosemicarbazonen einerseits und Proton oder zweiwertigen Übergangsmetallionen andererseits potentiometrisch bei einer konstanten Ionenstärke und verschiedenen Zusammensetzungen von Dioxan und Wasser als gemischtem Lösungsmittel untersucht. Die Methode von Bjerrum und Calvin nach der Modifikation von Irving und Rossotti wurde zur Evaluierung der Werte fürn undpL verwendet. Die Stabilitätskonstanten und β n -Werte wurden nach Sullivan et al. berechnet. Die WerteS min=χ2 wurden ebenfalls bestimmt. Die Reihenfolge der Stabilitätskonstanten war UO 2 2+ 〉 Cu2+ 〉 Ni2+ 〉 Co2+ 〉 Zn2+ 〉 Pb2+ 〉 Cd2+ 〉 Mn2+ 〉 Mg2+. Außerdem wurde der Effekt wechselnder Dielektrizitätskonstanten des Lösungsmittels auf die Stabilitätskonstanten der Komplexe bei einer Ionenstärke von 0.100M NaClO4 und einer Temperature von 20±0.5°C untersucht.
    Notes: Summary Equilibria between 2-hydroxy naphthaldehyde derivatives (semicarbazone and thiosemicarbazone) and proton or some bivalent metal ions have been investigated potentiometrically at a constant ionic strength and different compositions of the mixed solvent (dioxane: water). The method of Bjerrum and Calvin [1, 2], as modified by Irving and Rossotti [3], has been used to determine the values ofn andpL. The stability constants have been calculated following Sullivan et al. [4] to give β n values. The values ofS min=χ2 have also been calculated. The order of stability constants was found to be found to be UO 2 2+ 〉 Cu2+ 〉 Ni2+ 〉 Co2+ 〉 Zn2+ 〉 Pb2+ 〉 Cd2+ 〉 Mn2+ 〉 Mg2+. The effect of varying the dielectric constant of the medium on the stability constants of the complexes has also been investigated at an ionic strength of 0.100M NaClO4 and a temperature of 20±0.5°C.

    A new observation onHalobacterium halobium; light-induced volume flow through the whole organism (1984)

    Notes: Summary A new observation on theH. halobium cells is reported. It has been observed that when the cells are exposed to light a volume flow is observed through them. The magnitude of the light-induced volume flow depends on the intensity and wavelength of the exciting light and is also influenced by temperature. The phenomenon appears to be relevant to the physiology of the organism.
