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: This work provides a framework for minimizing the sensitivity of transmission-based sensors to beam steering without quantitative prediction of the severity of the beam-steering field, and introduces a parameter for characterizing beam- Steering severity.

TL;DR: In this article, the integrated intensities, self-and air-broadening coefficients of thirteen transitions of H216O in the 11980-12260 cm−1 region, belonging to the 2ν1+ν2+ν3 band, were measured.

TL;DR: In this article, a gas-phase decalin/air mixture was used to measure ignition delay times and ethylene concentration time-histories during decalin oxidation and pyrolysis, and negative-temperature-coefficient (NTC) behavior of decalin autoignition was observed at temperatures below 920 K.

TL;DR: A tunable diode laser absorption sensor near 2.7 μm, based on 1f-normalized wavelength-modulation spectroscopy with second-harmonic detection (WMS-2f), was developed to measure CO2 concentration in harsh combustion flows as mentioned in this paper.
