TL;DR: In order to suppress the overpressure and flame damage caused by the explosion of premixed methane-air, a self-built duct with a 10 × 10 × 100 cm was used to conduct an experimental study as discussed by the authors.

TL;DR: In this paper, the influence of H2 overpressure on the electrical and optical properties of GaAs epitaxial layer grown by the low-pressure MOCVD of TMG/AsH3/H2 system was studied.
Abstract: The influence of H2 overpressure on the electrical and optical properties of GaAs epitaxial layer grown by the low-pressure MOCVD of TMG/AsH3/H2 system was studied. It was demonstrated that high H2 overpressure was not necessary in the reaction process to reduce carbon contamination for low-pressure MOCVD. The carbon incorporation process in low-pressure MOCVD was discussed briefly.

TL;DR: In this paper, it was shown that the Poisson's ratio decreases with decreasing differential pressure (confining minus pore pressure) in gassaturated and liquid-saturated rocks.
Abstract: By analyzing experimental data we show that in many gas-filled rocks, the Poisson's ratio (PR) decreases with decreasing differential pressure (confining minus pore pressure). In many liquid-saturated rocks the opposite is true: PR increases with decreasing differential pressure. This means that in gassaturated rocks, PR decreases with increasing pore pressure and in liquid-saturated rocks it increases with increasing effective pressure. We confirm the generality of the observed effect by theoretically reproducing it via effective medium modeling. This effect can be used as a new tool for seismic pore pressure and pore fluid monitoring during production as well as for overpressure detection from surface seismic, cross-well, sonic logs and measurements ahead of the drill bit.

TL;DR: In this paper, the authors investigated the effect of hydrogen fraction in fuel (χ) ranging from 0 to 1.0 on flame evolution and pressure buildup within and outside the vented deflagration of stoichiometric hydrogen-methane-air mixtures.
