EQUAÇÕES LINEARES E NÃO LINEARES PARA PREVER O COMPORTAMENTO DE PROPRIEDADES FÍSICO-QUÍMICAS DE COMBUSTÍVEL DE AVIAÇÃO MISTURADO COM BIOQUEROSENE DROP-IN ALTERNATIVO

Química Nova (2018)

Bruno K. V. Iha Leila Ribeiro dos Santos Lenilson Santos Maria Esther Sbampato José Atílio Fritz Fidel Rocco

ALTERNATIVE BIOQUEROSENE DROP-IN.Density, viscosity and calorific values are important physical properties to affect the utilization of biofuel.In this work, mixtures of farnesane and a "jet fuel", QAv-1, were used to study the variation of density and kinematic viscosity as a function of the volumetric fraction of farnesane and temperature.Experimental measurements were carried out for nineteen farnesane blends and pure farnesane and QAv-1, at four temperatures in the range of 293 -323 K. Variation of high heating (HHV) and low heating (LHV) values were also determined for different blends of farnesane/ QAv-1.Several empirical correlations were used to predict the density, the kinematic viscosity, HHV and LHV values.By using some of these empirical correlations, the estimated values of those three properties studied are in excellent agreement with the experimental data, with low absolute average prediction error.

Dysprosium optogalvanic spectroscopy in a hollow cathode lamp

Journal of the Optical Society of America B (2023)

Jhonatha Ricardo dos Santos Patrícia Bueno Jonas Jakutis Neto Alessandro Rogério Victor Luiz Felipe Nardin Barreta

This work presents data obtained from optogalvanic spectroscopy (OGS) of dysprosium (Dy) using a commercial hollow cathode lamp. Combining laser beams from two tunable dye lasers, it was possible to identify 13 electronic transitions from excited states of the atom not observed or registered in published papers and the NIST database; these lines were observed between 555–575 nm and 585–615 nm. The study of 13 two-step transitions found in this work complement the available data for the Dy which may support other research or any work using this atom.

Observation of the ¹⁶²Dy–¹⁶⁴Dy Isotope Shift for the 0 → 16 717.79 cm⁻¹ Optical Transition

Applied Spectroscopy (2017)

Luiz Felipe Nardin Barreta Alessandro Rogério Victor Patrícia Bueno Jhonatha Ricardo dos Santos Carlos Alberto Barbosa da Silveira

In this work, we report a newly observed isotope shift between 162Dy and 164Dy isotopes for the 0 → 16 717.79 cm-1 (598.003 nm) optical transition. We compared the newly observed results against two other lines (597.452 nm and 598.859 nm), which we measured in this work, and were already reported in the literature. The newly observed 162-164 Dy isotope shift, shows at least a 20% larger isotope shift than the isotope shifts for the other two lines investigated. The larger 162-164 isotope shift observed for the 598.003 nm line could lead to an increased isotope selectivity for atomic vapor laser isotope separation (AVLIS). Hence, this line could be a good choice for application in AVLIS. Experimental data available in the literature for the 597.452 nm and 598.859 nm lines, enabled us to perform simulations of spectra for both lines, in order to confirm the accuracy of our experimental measurements.
