Critically pressured free-gas reservoirs below gas-hydrate provinces
Nature, 2004Palaeoceanographic data have been used to suggest that methane hydrates play a significant role in global climate change. The mechanism by which methane is released during periods of global warming is, however, poorly understood. In particular, the size and role of the free-gas zone below gas-hydrate provinces remain relatively unconstrained, largely ...

Gas Velocities from Free Fall Gas Atomiser
Powder Metallurgy, 1996AbstractThe flow field of a free fall gas atomiser has been measured in three dimensions using hot wire anemometry and a pitot tube for confirmation of axial flow speeds. A finite difference based fluid dynamics package has then been used to model the gas flow from the atomiser geometry.

Turbulence in helium-gas free convection
Physical Review A, 1989Results on a Rayleigh-B\'enard experiment in helium gas at 5 K in a cylindrical cell of aspect ratio 1 are presented. The Rayleigh number spans a range from ${10}^{5}$ to ${10}^{12}$. A large-scale coherent flow is observed via the correlation of two adjacent temperature probes.

Free and enclosed inertial active gas
Soft Matter, 2023In this work, an inertial active gas in three dimensions made of spherical non-interactive active Brownian particles with both translational and rotational inertia (IABPs) is studied, in both a free and an enclosed scenario.

Gas lenses for gas loaded free electron lasers
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1988Abstract After briefly describing the basic properties of thermohydrodynamic gas lenses, we show that their appropriate use in a gas loaded free electron laser increases the small signal gain by a factor even higher than 2.

Traceable Reference Gas Mixtures for Sulfur-Free Natural Gas Odorants
Analytical Chemistry, 2014The first reference gas mixtures of sulfur-free natural gas odorants that are traceable to the International System of Units (SI) have been produced and their compositions validated. These mixtures, which contain methyl acrylate and ethyl acrylate at amount fractions between 1.1 and 2.1 μmol mol(-1), can be used to underpin measurements of sulfur-free ...

The structure of a solid, its composition of atoms, as well as the electronic, optical and lattice properties are essentially determined by the electrons. However, not all electrons of the atoms constituting the solid are involved in the same way. At the beginning of Chap.
