    Encapsulation of Proteins in Bulk and Thin Film Sol-Gel Matrices (1997)
    Springer
    Journal of sol gel science and technology 8 (1997), S. 629-634 
    Details
    ISSN: 1573-4846
    Schlagwort(e): protein encapsulation ; absorption spectroscopy ; thin films ; cytochrome c
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Abstract This paper considers the nature of the interactions between the sol-gel derived inorganic matrix and a specific biomolecule, cytochrome c. Optical absorption and impedance spectroscopies are used to characterize the influence of synthesis conditions on the protein's stability and conformation within the silica matrix. In some instances, encapsulation within the sol-gel matrix provides stabilization. For example, protein denaturation is reversible and aggregation is prevented. Moreover, the drying process does not negatively affect the protein; it is possible to regenerate the aged gel state by rehydration. The flexibility of the sol-gel process enables high quality cytochrome c-doped SiO2 thin films to be prepared. These films possess the characteristic reactivity and chemical function of cytochrome c in solution.

    Optically Pumped Far-Infrared Laser Lines of Methanol Isotopomers: 12CD3OH, 12CH3OD, and 12CH2DOH (2000)
    Springer
    International journal of infrared and millimeter waves 21 (2000), S. 477-483 
    Details
    ISSN: 1572-9559
    Schlagwort(e): 12CD3OH ; 12CH3OD ; 12CH2DOH ; new far-infrared laser lines ; optically pumped far-infrared laser ; laser frequencies ; relative intensity ; relative polarization ; pump-frequency offset
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract Twenty-seven new FIR, far-infrared, laser lines from the isotopomers of methanol: 12CD3OH, 12CH3OD, and 12CH2DOH, were obtained by optically pumping the molecules with an efficient cw CO2 laser. The CO2 laser provided pumping from regular, sequence, and hot-band CO2 laser transitions. The 2 m long far-infrared cavity was a metal-dielectric waveguide closed by two, flat end mirrors. Several short-wavelength (below 100 μm) lines were observed. The frequencies of 28 laser lines observed in this cavity (including new lines and already known lines) were measured with a fractional uncertainty limited by the fractional resetability of the far-infrared laser cavity, of 2 parts in 107.

    New FIR laser lines and frequency measurements for optically pumped CD3OH (1987)
    Springer
    International journal of infrared and millimeter waves 8 (1987), S. 653-662 
    Details
    ISSN: 1572-9559
    Schlagwort(e): CD3OH laser lines ; laser frequency measurements ; optically pumped FIR laser ; new laser lines ; relative intensity ; relative polarization
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract Twenty new cw FIR laser lines in CD3OH, optically pumped by a CO2 laser, are reported. The frequencies of 39 of the stronger laser lines were measured relative to stabilized CO2 lasers with a fractional uncertainty, as determined by the reproducibility of the FIR frequency itself, of 2 parts in 107.

    Far infrared laser frequencies of CH3OD and N2H4 (1991)
    Springer
    International journal of infrared and millimeter waves 12 (1991), S. 1161-1166 
    Details
    ISSN: 1572-9559
    Schlagwort(e): CH3OD ; N2H4 ; molecular laser lines ; laser frequency measurements ; optically pumped far infrared lasers
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract The frequencies of 26 laser lines with wavelengths between 57 and 534 μm have been measured in the optically pumped laser gases CH3OD and N2H4. A pair of stabilized cw 12CO 2 lasers was used as a frequency standard for the heterodyne frequency measurements. Seven of the 26 lines are new.
