    Notes: To examine two-electron transfer producing negative ions from positive ions, an apparatus using an alkali-metal target has been developed. Positive ions formed by electron impact in an ion source collided with alkali-metal vapor in a target chamber. Negative ions formed by two-electron transfer have been analyzed with a single-focusing mass spectrometer. Precursor positive ions and product negative ions have been identified from the apparent masses in the negative-ion spectra. Using the target density dependence of the negative-ion intensity, the processes of negative-ion formation were determined to be double-electron transfer in one collision or successive single-electron transfer in two collisions. The cross section of these processes has been estimated from the peak area of positive- and negative-ion spectra and the target density evaluated using the vapor-pressure curve as a function of the temperature of the alkali-metal cell. A cross section for He−-ion formation in the Cs target with successive single-electron transfer have been evaluated to be 1.40×10−30±0.2 cm4 at a collision energy of 2.0 keV, which showed the fair agreement with the values reported by Donnally and Thoeming [Phys. Rev. 159, 87 (1967)]. The double-electron transfer cross section for C2−-ion formation from a C2+ ion with a Cs target has been evaluated as 7.03×10−18±0.1 cm2 at 3.0 keV. For O−-ion formation from O2+ ions, four broad peaks were observed due to the kinetic energy releases at dissociation which were 7.3, 3.4, 1.1, and 0.014 eV at full width at half maximum. Since the kinetic energy releases of the broad peaks corresponded with those by Peterson and Bae [Phys. Rev. A 30, 2807 (1984)], the peak extents have been explained as the dissociations of the excited neutral formed from exothermic neutralization. This two-electron transfer from an alkali-metal target offers a good advantage for the determination of the dissociation mechanism for excited neutral particles by means of the negative-ion detection method.

    Preparation of blood globin through carboxymethyl cellulose chromatography (1981)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: A simple and inexpensive procedure for globin preparation from blood of various animals was developed in order to use globin as human food. Carboxymethyl cellulose was most effective among some cation exchangers tested, although amounts of haemoglobin applied to 1 g of the exchanger should be limited to less than 70 mg. The behaviour of adsorbing haem or haemin to the exchanger could not be explained only by a general theory of ion exchange chromatography. Yields and Fe contents of globin preparations from various haemoglobins by this procedure ranged from 67 to 80% and from 0.008 to 0.03% respectively, except for a chicken haemoglobin sample.

    Antioxidative Activity and Gelling Rheological Properties of Dried Egg White Glycated with a Rare Keto-hexose through the Maillard Reaction (2004)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 69 (2004), S. 0

    Notes: : The functional properties of egg white (EW) glycated with a rare D-psicose and 2 alimentary sugars (D-fructose and D-glucose) were investigated. Glycation led not only to the formation of cross-links but also to the formation of antioxidative substances to EW, the extent of which depended on the sugar used, modification, and incubation time. The temporal development of browning and fluorescence of psicose-EW was relatively faster than those of fructose-EW and glucose-EW. The psicose-EW showed the greater 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5carboxanilide (XTT) reducibility, 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activity, and gelling rheological properties. These results indicated that psicose-EW as a food ingredient might have the ability to improve gelling behavior and decrease oxidation reactions during food processing and storage.
