Structural characterization of eutectic aqueous NaCl solutions under variable temperature and pressure conditions

The structure of amorphous NaCl solutions produced by fast quenching is studied as a function of pressure, up to 4 GPa, by combined neutron diffraction experiments and classical molecular dynamics simulations. Similarly to LiCl solutions the system amorphi ...

Role of sulfur in BaVS3 probed by S K-edge absorption spectroscopy

László Forró, Helmuth Berger

We show that the quasi-1D behavior of BaVS3 can be understood analyzing the X-ray absorption near edge spectra at the sulfur K edge. Linear dichroism experiments, analyzed with the help of ab initio calculations, reveal two strong and polarization dependen ...

Synthesis, structural determination, theoretical studies and catalytic activity of Mn(II) complex of N-isonicotinyl phosphoric triamide ligand

Kurt Schenk, Farzaneh Fadaei Tirani

synthesized and characterized by H-1, C-13, P-31 NMR and IR spectroscopies. The reaction of MnCl2 center dot 4H(2)O with L led to the formation of a new 3D system {MnL2Cl2}(n)center dot 34CH(3)OH (C-1). X-ray crystallographic data revealed that the ligand ...

Rotor Design Optimization for a Reaction Sphere Actuator

Yves Perriard, Leopoldo Rossini

This paper presents the rotor design optimization for a reaction sphere (RS) actuator. The RS is a permanent-magnet synchronous spherical actuator whose rotor is magnetically levitated and can be accelerated about any desired axis. The RS is composed of an ...

Planck 2013 results. XXVI. Background geometry and topology of the Universe

Julien Lesgourgues, Jason Douglas McEwen, Fabio Finelli

The new cosmic microwave background (CMB) temperature maps from Planck provide the highest-quality full-sky view of the surface of last scattering available to date. This allows us to detect possible departures from the standard model of a globally homogen ...

Hybrid FEM-analytical force and torque models of a reaction sphere actuator

Yves Perriard, Leopoldo Rossini

This paper presents a hybrid FEM-analytical model for the magnetic flux density, the force and torque of a Reaction Sphere (RS) actuator for satellite attitude control. The RS is a permanent magnet synchronous spherical actuator whose rotor is magnetically ...

On The Convergence Of The Affine Hull Of The Chvatal-Gomory Closures

Yuri Faenza, Marco Di Summa

Given an integral polyhedron P subset of R-n and a rational polyhedron Q subset of R-n containing the same integer points as P, we investigate how many iterations of the Chvatal-Gomory closure operator have to be performed on Q to obtain a polyhedron conta ...

Triangle-Free Geometric Intersection Graphs with Large Chromatic Number

Bartosz Maria Walczak, Michal Lason

Several classical constructions illustrate the fact that the chromatic number of a graph may be arbitrarily large compared to its clique number. However, until very recently no such construction was known for intersection graphs of geometric objects in the ...

Shape and Size-Tailored Pd Nanocrystals to Study the Structure Sensitivity of 2-Methyl-3-butyn-2-ol Hydrogenation: Effect of the Stabilizing Agent

Lioubov Kiwi, Rocio Micaela Crespo Quesada

Uniform Pd nanocrystals of cubic, octahedral and cube-octahedral shapes were synthesized via a solution-phase method using two stabilizers: poly (vinyl pyrrolidone) (PVP) and di-2-ethylhexylsulfoccinate (AOT) and tested in the hydrogenation of 2-methyl-3-b ...
