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 article, a compact and calibration-free carbon monoxide sensor approach utilizing the wide current-tunability of 2.3 μm VCSELs is reported, where a separate reference cell is avoided by filling the reference gas (methane) in the photodetector housing.
