Analogous to most new methods in science, photoacoustic spectroscopy (PAS) grew out of
an advance in technology, in this case the dramatic improvement in novel light sources …

Photoacoustic spectroscopy (PAS) is based on the absorption of electromagnetic radiation
by analyte molecules. The absorbed energy is measured by detecting pressure fluctuations …

Acoustic devices are widely applied in telephone communication, human–computer voice
interaction systems, medical ultrasound examination, and other applications. However …

Photoacoustic (PA) spectrum is a promising method in SF 6 decomposition product
detection. To develop an on-line monitoring device, a gas detection system based on PA …

Several biodiesel fuel samples produced from rapeseed oil by the noncatalyzed
transesterification reaction with supercritical ethanol at various temperatures from (593 to …

In this Letter, thermal lens and open cell photoacoustic techniques are used to measure the
thermal properties of biodiesel oils. The absolute values of the thermal effusivity, thermal …

PVT, saturated liquid density and two-phase (vapor-pressure) properties of one of the main
component of the biofuel (methyl palmitate), produced from a soybean, have been …

A near-infrared (NIR) dual-channel differential acetylene (C 2 H 2) detection system was
experimentally demonstrated based on tunable diode laser absorption spectroscopy …

Thermodynamic properties of compressed fuels as density at liquids phase (P ρ T data) and
two liquids-gas phases as saturated pressure, density, and temperature (PS, ρ S, TS) are …

Bio-jet fuel is a key element in the aviation industry to reduce operating costs and
environmental impacts. Bio-jet fuel is a complex mixture of four hydrocarbons (n-alkanes …
