Air–sea coupling during coastal upwelling was examined through idealized three-dimensional numerical simulations with a coupled atmosphere–ocean mesoscale model. Geometry, topography, and initial and
boundary conditions were chosen to be representative of summertime coastal conditions off the Oregon coast. Over the 72-h simulations, sea surface temperatures were reduced several degrees near...
The solid solutions of InGa₁₋ₓFeₓCuO₄, InFeCu₁₋ₓMgₓO₄, and InGa₁₋ₓFeₓCu₁₋ₓMgₓO₄ were
synthesized and characterized through the use of X – ray and neutron diffraction, and DC –
magnetism measurements. All compositions of InGa₁₋ₓFeₓCuO₄ are single phase and crystallize
in the R3m space group, but a transformation to the spinel InFeMgO₄ structure was...
Includes general information about journal costs and costs of commercial versus society publications. Spreadsheet represents the journals in which faculty in the Chemistry Department most often publish and includes journal title, cost, impact factor, publisher, and information about whether the journal is published by a scholarly society or a for-profit...
Mapping out multidimensional potential energy surfaces has been a goal of
physical chemistry for decades in the quest to both predict and control chemical
reactivity. Recently a new spectroscopic approach called Femtosecond Stimulated Raman
Spectroscopy or FSRS was introduced that can structurally interrogate multiple
dimensions of a reactive potential energy...
The effect of quasi-hydrostatic pressure upon the ferromagnetic ground state of magnetodielectric, double-
perovskite La₂ MnNiO₆ is investigated using x-ray absorption spectroscopy and diffraction measurements in a
diamond anvil cell. The Mn-O-Ni superexchange interaction that gives rise to ferromagnetism in this cation-
ordered structure is stable to at least 38...
Background: There is a long-term interest in running the fission reaction backward, i.e., studying the "inverse fission" of uranium. The recent availability of beams of n-rich fission fragments has stimulated interest in this endeavor.
Purpose: To search for inverse fission in the reactions Sn-¹²⁴,Sn-¹3² + Mo-¹⁰⁰.
Method: In the Sn-¹²⁴...
We report an experimental and theoretical study of single-molecule inner-shell photoemission measured over an extended range of photon energies. The vibrational intensity ratios I (nu = 1)/I (nu = 0) from the C 1s photoelectron spectra of carbon monoxide, although mostly determined by the bond length change upon ionization, are...
Fusion excitation functions for the reactions of Sn-¹²⁴,Sn-¹³² with Ca-⁴⁰,Ca-⁴⁸ were measured at energies near and below the Coulomb barrier. Weak sub-barrier fusion enhancement accounted for by coupling to the first 2(+) and 3(-) states in the target and projectile was observed for Sn-¹²⁴,Sn-¹³² + Ca-⁴⁸. However, the Sn-¹²⁴,Sn-¹³² +...
X-ray photoemission spectroscopy is used in a great variety of research fields; one observable is the sample's stoichiometry. The stoichiometry can be deduced based on the expectation that the ionization cross sections for innershell orbitals are independent of the molecular composition. Here we used chlorine-substituted ethanes in the gas phase...
Three general types of swimbladders were found in the eight species of myctophids studied: gas-filled, fat-invested, and atrophied or reduced. Small specimens of all species had thin-walled, gas-filled swimbladders. Large specimens of Stenobrachius leucopsarus had fat-invested swim-bladders and large Diaphus theta had either gas-filled or atrophied swimbladders, as found by...
Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...
