Refractive index of a dilute Bose gas

Physical Review A, 1995
We derive the dispersion relation for the propagation of quasiresonant light with frequency ωL in an ultracold gas of bosonic atoms in the dilute regime, i.e., for an atomic density ρ0≪(ωL/c)3. In our calculation, valid up to order 2 in density, two types of corrections to the Lorentz-Lorenz formula for the refractive index appear. The first one is due

Gas Turbine Gas Fuel Composition Performance Correction Using Wobbe Index

Journal of Engineering for Gas Turbines and Power, 2010
Gas turbine thermal performance is dependent on many external conditions, including fuel gas composition. Measured performance must be corrected to specified reference conditions prior to comparison against performance specifications. A performance correction for fuel composition is thus required.

DeepReI: Deep learning-based gas chromatographic retention index predictor

Analytica Chimica Acta, 2021
Retention index in gas chromatographic analyses is an essential tool for appropriate analyte identification. Currently, many libraries providing retention indices for a huge number of compounds on distinct stationary phase chemistries are available. However, situation could be complicated in the case of unknown unknowns not present in such libraries ...
