Electrochemical Detection of Single Molecules
The electrochemical behavior of a single molecule can be observed by trapping a small volume of a dilute solution of the electroactive species between an ultramicroelectrode tip...
Enhanced Raman scattering by molecules adsorbed at the surface of colloidal spheroids
Equations are derived and calculations are presented for the electrodynamic mechanism of enhanced Raman scattering by molecules at the surface of prolate and oblate spheroids in...
Extremely Large Variations of Atmospheric <sup>14</sup> C Concentration During the Last Glacial Period
A long record of atmospheric 14 C concentration, from 45 to 11 thousand years ago (ka), was obtained from a stalagmite with thermal-ionization mass-spectrometric 230 Th and acce...
Signatures of relativistic neutrinos in CMB anisotropy and matter clustering
We present a detailed analytical study of ultra-relativistic neutrinos in cosmological perturbation theory and of the observable signatures of inhomogeneities in the cosmic neut...
Effects of 6 weeks of therapy with oral doses of ICI 204,219, a leukotriene D4 receptor antagonist, in subjects with bronchial asthma. ACCOLATE Asthma Trialists Group.
The efficacy of 6 wk of therapy with oral ICI 204,219, a selective leukotriene D4 (LTD4) receptor antagonist, was evaluated in subjects with moderate asthma during a multicenter...
Filtering of Milankovitch Cycles by Earth's Geography
Abstract Earth's land-sea distribution modifies the temperature response to orbitally induced perturbations of the seasonal insolation. We examine this modification in the frequ...
New chronology for the late Paleocene thermal maximum and its environmental implications
Research Article| October 01, 2000 New chronology for the late Paleocene thermal maximum and its environmental implications U. Röhl; U. Röhl 1Department of Geosciences, Bremen U...
Theory of Electron Band Tails and the Urbach Optical-Absorption Edge
The density of states $\ensuremath{\rho}(E)$ in the tail for an electron in a correlated Gaussian random potential in three dimensions is constructed from first principles by me...
Nanosphere Lithography: Surface Plasmon Resonance Spectrum of a Periodic Array of Silver Nanoparticles by Ultraviolet−Visible Extinction Spectroscopy and Electrodynamic Modeling
In this paper we measure the optical extinction spectrum of a periodic array of silver nanoparticles fabricated by nanosphere lithography (NSL) and present detailed comparisons ...
The electronic states of Ar+2, Kr+2, Xe+2. I. Potential curves with and without spin–orbit coupling
The low-lying states of Ar+2, Kr+2, and Xe+2 have been investigated using the POL CI method. Spin–orbit coupling has been included with a simple atoms-in-molecule approach. The ...
