The aim of this work was to evaluate the emission of nitrous oxide (N2O) using a diesel engine at laboratory scale without a catalytic converter with diesel/biodiesel blends (%) of 95:5 (B5), 90:10 (B10), 85:15 (B15), 80:20 (B20), 75:25 (B25), and 50:50 (B50). Measurements of N2O in the exhaust gas were made using an experimental setup based on photoacoustic spectroscopy using a quantum cascade laser that was validated to be selective and sensitive in the range from 1.7 to 2.72 ppmv. According… 
Environmental impact of combustion of ethanolic biodiesel/diesel blends from several feedstocks on the gas emission levels in the atmosphere
Evaluated ethanolic biodiesel from several feedstocks and engine operational conditions and the effect of engine operating conditions and biodiesel content in the blends during their combustion on the exhaust emissions point to crambe and macaw as more environmentally sustainable feedstocks for biodiesel production because they generate less greenhouse gas emissions.
Photoacoustic spectroscopy for detection of N2O emitted from combustion of diesel/beef tallow biodiesel/sugarcane diesel and diesel/beef tallow biodiesel blends
Nitrous oxide (N2O) is an important greenhouse gas. Emissions of this gas are generated by the combustion of fossil fuels, mainly in the transportation sector worldwide. Biofuel is a promising
Study of Gaseous Emissions Derived from the Combustion of Diesel/Beef Tallow Biodiesel Blends
Air pollution is one of the main environmental problems of modern society. The road and transportation segment is a key source of polluting gases worldwide. In its research for transportation’s
Pollutant gas and particulate material emissions in ethanol production in Brazil: social and environmental impacts
This work evaluates the scenario of pollutant gas emissions and particulate material that comes from the biomass burning process involved in ethanol production cycle, in the city of Campos dos Goytacazes, Brazil.
Photoacoustic Spectroscopy for the Quantification of N2O in the Off-Gas of Wastewater Treatment Plants.
Different configurations of photoacoustic setups for the online-measurement of gaseous N2O, employing semiconductor lasers at 2.9 and 4.5 μm, were developed and tested and found that the use of a quantum-cascade laser emitting at about 4.53 μm yielded the highest sensitivity, but also observed a strong cross-sensitivity to humidity.
Quartz crystal microbalance and photoacoustic measurements in dental photocuring.
Two techniques, Quartz Crystal Microbalance and Photoacoustic Spectroscopy, were used to monitor the real-time cure and to obtain the optical absorption spectra of resins, respectively, and the results confirmed the advantages of using PAS and QCM to study polymerisation kinetics.


Nitrous oxide emissions from gasohol, ethanol and CNG light duty vehicles
A sample of 21 light duty vehicles powered by Otto cycle engines were tested on a chassis dynamometer to measure the exhaust emissions of nitrous oxide (N2O). The tests were performed at the Vehicle
Gaseous and Particulate Emissions from Diesel Engines at Idle and under Load: Comparison of Biodiesel Blend and Ultralow Sulfur Diesel Fuels.
The emission profiles demonstrate the effects of fuel type, engine calibration, and emission control system, and they can be used as source profiles for apportionment, inventory, and exposure purposes.
Exhaust Emissions of Biodiesel, Petrodiesel, Neat Methyl Esters, and Alkanes in a New Technology Engine†
Biodiesel is a renewable, alternative diesel fuel of domestic origin derived from a variety of fats and oils by a transesterification reaction; thus, it consists of the alkyl esters, usually methyl
Nitrous Oxide (N2O) Emissions from Vehicles
N2O is an important greenhouse gas and accurate emission data are required to assess its impact on global climate. It is well established that automobiles, particularly those equipped with 3-way
A Sulfur Hexafluoride Sensor Using Quantum Cascade and CO2 Laser-Based Photoacoustic Spectroscopy
The laser photoacoustic spectrometers described in this work have been developed for gas detection at small concentrations and detection limits of 20 ppbv for CO2 laser and 50 ppbV for quantum cascade laser were obtained.
