Infrared laser-absorption sensing for combustion gases

TL;DR: Graphene, reduced graphene oxide (rGO) and derived materials have emerged as promising solutions for applications in renewable energy storage/conversion devices as mentioned in this paper, which are known to simultaneously exhibit large specific surface area, high electrical conductivity, good chemical stability, high mechanical strength and flexibility.

TL;DR: Recent progress towards the miniaturization and integration of optical gas sensors, with a focus on low-cost and low-power consumption devices is reviewed.

TL;DR: The U.S. Department of Energy will provide public access to these results of federally sponsored research in accordance with the DOE Public Access Plan as mentioned in this paper, which can be found at http://energy.gov/downloads/doe-public-access-plan.

TL;DR: Laser absorption spectroscopy (LAS) has been rapidly developed and widely applied to combustion diagnosis in recent decades as mentioned in this paper, and is a cost-effective tool for measuring multiple combustion parameters.

TL;DR: In this paper, the strongest vibrational band of acetylene near 13.7μm was used to develop a highly sensitive absorption diagnostic, which was demonstrated by measuring acetylene formation during the shock-heated pyrolysis and oxidation of propene.

TL;DR: The CEAS absorption gain factors significantly improved the detection sensitivity over conventional single-pass measurements, and the potential of using CEAS to improve shock-tube studies of nonequilibrium electronic-excitation processes at high temperatures is demonstrated.

TL;DR: In this article, a diode-laser based closed-loop control system was developed to nonintrusively optimize a pulsed, 50-kW dump combustor, which used temperature and water mole fraction measurements obtained at 10-kHz rates from the peak absorbance values of H 2 O features near 1.4 μm.

TL;DR: In this article, an erbium-fiber femtosecond laser is used to produce chirped broadband pulses that scan from 1.67 to 1.44 μm at a rate of 0.6 nm/ns.
