The dynamical transition to step-flow growth during molecular-beam epitaxy of GaAs(00l)
(Elsevier, 1993-12-20)
Scanning tunneling microscopy studies have been performed on GaAs homoepitaxial films grown by molecular-beam epitaxy. Images show that in the earliest stages of deposition the morphology oscillates between one with ...
Time-lapse total internal reflection fluorescence video of acetylcholine receptor cluster formation on myotubes
(Wiley Subscription Services, Inc., A Wiley Company, 1994-09)
To study when and where acetylcholine receptor (AChR) clusters appear on developing rat myotubes in primary culture, we have made time-lapse movies of total internal reflection fluorescence (TIRF) overlaid with schlieren ...
Characteristic infrared frequencies of rotational isomers of alkyl chlorides
(Elsevier, 1962)
A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond. ...
Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
Time dependencies in the occurrences of epileptic seizures
(Elsevier, 1994-01)
A new method of analysis, developed within the framework of nonlinear dynamics, is applied to patient recorded time series of the occurrence of epileptic seizures. These data exhibit broad band spectra and generally have ...
Lipoxygenase isoenzymes: A spectroscopic and structural characterization of soybean seed enzymes
(Elsevier, 1989-02-15)
Applying recent developments in protein purification techniques, a number of lipoxygenase isoenzymes have been isolated in satisfactory quantities for a detailed physical and structural characterization. Four seed isoenzymes ...
Vibrational analyses of 2,4-dichloropentane and 2,4,6-trichloroheptane
(Elsevier, 1974-04)
This study of the vibrational spectra of 2,4-dichloropentane and 2,4,6-trichloroheptane uses normal coordinate calculations as a probe for the presence of different molecular conformers. The calculations use a complete ...
Vibration-rotation energies of tetrahedral XY4 molecules : Part II. The fundamental [nu]3 of CH4
(Elsevier, 1961)
The matrix elements derived in the first paper of this series are used to compute the frequencies of the tetrahedral fine structure components of the rotational lines of the fundamental [nu]3 of CH4. The theoretically ...
Self Assembly and Optical Properties of Dendrimer Nanocomposite Multilayers
(WILEY-VCH Verlag, 2007-08-07)
Ultrathin multilayers are important for electrical and optical devices, as well as for immunoassays, artificial organs, and for controlling surface properties. The construction of ultrathin multilayer films by electrostatic ...
