Evanescent luminescence and nanometer-size light source
(Elsevier, 1991)
Subwavelength light sources have been constructed with the aid of luminescent materials. These EXCITOR (exciton transmitted optical radiation) sources are of both theoretical and practical interest. The production of ...
The diffusion-limited reaction A+B→0 on a fractal substrate
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-12)
We show in this paper how the segregation of reactants in the diffusion-limited reaction A+B→0 on a fractal substrate arises. For spectral dimensions d s ⩽ 2 we obtain segregation controlled by the source and/or the intrinsic ...
A continuous flow probe method for on‐line introduction of liquid samples for detection by laser desorption with resonant two‐photon ionization in supersonic beam mass spectrometry
(The American Institute of Physics, 1991-04)
A continuous flow probe is used as a direct inlet source for injection of liquid samples into a time‐of‐flight (TOF) mass spectrometer. The direct liquid inlet is coupled to laser desorption as a means of rapidly vaporizing ...
Electron diffraction studies of hot molecules. IV. Asymmetries of nonbonded distribution functions of SF6, SiF4, and CF4
(The American Institute of Physics, 1984-11-01)
Highly significant improvements in the agreement between observed and calculated intensities of electrons diffracted by hot molecules were obtained by optimizing the skew parameter â for the nonbonded distributions. Derived ...
Optical Mapping of the Phonon Density of States in Molecular Solids Supported by: NSF Grant GP-18718 and NM Grant NS08116.
(WILEY-VCH Verlag, 1972-11-01)
No Abstract.
Gas Sensing Characteristics of Ultrathin TiO 2− x Films Investigated with XPS, TPD and In Situ Resistance Measurements
(John Wiley & Sons, Ltd., 1997-02)
Ultrathin Pt/TiO 2− x sensing films are characterized to investigate the adsorption and reaction processes that cause resistance changes. The films are prepared by oxidizing films with a nominal thickness of 65 Å Pt ...
Streptavidin-biotinylated IgG conjugates: a simple procedure for reducing polymer formation
(Elsevier, 1992-04)
Disulfide links of the IgG2ak anti-ovarian carcinoma antibody, 5G6.4, were site-specifically biotinylated [[approximate]2 biotins/ IgG2a] using a novel crosslinking procedure using the biotin derivatized ETAC (equilibrium ...
The absorption and magnetic circular dichroism spectra of matrix-isolated Os18O4 and Os16O4
(Elsevier, 1984-09)
Matrix absorption and magnetic circular dichroism studies on Os16O4 and Os18O4 have been carried out to clarify the number of electronic transitions present in the region. The spectra show that the irregular vibrational ...
Exciton Superexchange, Resonance Pairs, and Complete Exciton Band Structure of 1B2u1B2u Naphthalene
(The American Institute of Physics, 1971-07-15)
A method for the determination of complete exciton band structures in molecular crystals is given. Pairwise exciton interactions are derived from resonance‐pair data using an exciton “superexchange” approach. Koster and ...
