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, a gas cell, using optically contacted sapphire windows to form a hot vapor seal, has been created for high temperature fundamental spectroscopy studies, and it is designed to operate at temperatures from 280-2273 K and pressures from vacuum to 1.3 bar.

TL;DR: In this article, an infrared fiber-optic spark plug probe was developed that can measure the instantaneous fuel-air ratio of the unburned fuelair mixture near the spark plug in the cylinder of a production automobile engine.

TL;DR: In this article, the combined effects of radiator-perturber collisions and radiator translational motion in the context of foreign gas broadening of optical transitions in neutral radiators are investigated.

TL;DR: A new method based on simulated annealing is developed to obtain tomographic reconstructions based on multispectral absorption spectroscopy that is able to exploit the spectral information content, to incorporate various a priori information, and to ameliorate the ill-posedness of the tomographic inversion problem.
