Exchange rate misalignments, interdependence, crises, and currency wars: an empirical assessment
(2013-12-09)
Este trabalho tem por objetivo comparar metodologias distintas para cálculo de desalinhamento cambial além de testar a hipótese se as taxas de câmbio dos diversos países sofrem influencia apenas dos seus próprios fundamentos ...
State-selective charge exchange from Na(3s) and Na*(3p) by highly charged ions
(IOP Publishing, 2010-08)
State-selective charge exchange cross sections and momentum spectra are calculated for collisions of Xe18+ and Xe54+ ions with Na(3s) and Na*(3p) over the energy range of 0.1–10.0 keV/amu. The classical trajectory Monte ...
Evidence of electron saddle swap oscillations in angular differential ion-atom charge exchange cross sections
(IOP Publishing, 2012-09)
State selective charge exchange processes in 1-10keV/amu Ne 8++Na(3s) collisions were measured by means of the magneto-optical trap recoil-ion momentum spectroscopy technique and compared to classical trajectory Monte Carlo ...

Numerical simulation of cation exchange in fine coarse seawater slurry pipeline flow
(Elsevier, 2018)
Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of
seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...

Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of
seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...
A new SERS substrate based on niobium lead-pyrophosphate glasses obtained by Ag+/Na+ ion exchange
(2018-12-20)
Surface-enhanced Raman scattering (SERS) is one of the most sensitive methods for the detection of adsorbed molecules on the nanostructured coinage-metal surface. The enhancements in the order of 104–106 are routinely ...
Faujasites exchanged with alkylammonium cations applied to basic catalysis
(Elsevier B.V., 2019-07-01)
NaX and NaY faujasites (with Si/Al ratios of 1.3 and 2.5, respectively) were subjected to different degrees of ionic exchange with linear monoalkylammonium cations containing between 1 and 6 carbon atoms. The products were ...
