Henry's law and accumulation of weak source for crust-derived helium: A case study of Weihe Basin, China

Journal of Natural Gas Geoscience, 2017
Crust-derived helium is generated from the radioactive decay of uranium, thorium and other radioactive elements in geological bodies. Compared with conventional natural gas, helium is a typical weak source gas as a result of extremely slow generation ...

Helium additions to MIG shielding gas - an economic option? [PDF]

, 2011
An investigation has been carried out to establish the technical and economic benefits of adding two levels of helium to a normal shielding gas. Technically no adverse issues were established using the two levels of helium, and the most significant ...

Resolving Complex Multiscale Structure of Magneto‐ and Electroactive Polymer Composites With an Ionic Liquid

Advanced Materials, EarlyView.
Multiscale ionic liquid segregation into nano‐sized domains in the unconfined amorphous polymer phase and into micron‐sized pores enables a coupled magneto‐ and electroactive responses. ABSTRACT A multiscale understanding of the structure of ionogels – nanoparticle‐free polymer composites incorporating ionic liquids – is essential for enhancing their ...

Multiple stellar populations and their influence on blue stragglers

, 2010
It has become clear in recent years that globular clusters are not simple stellar populations, but may host chemically distinct sub-populations, typically with an enhanced helium abundance. These helium-rich populations can make up a substantial fraction

Helium Flux from the Craton by Diffusion through Its Pore System [PDF]

Lithosphere
Most radiogenic helium in natural gases is interpreted as a product of helium generation within the crystalline continental crust; however, the pathways to overlying sedimentary basins remain unclear.

In-situ measurement of the permittivity of helium using microwave NbN resonators

, 2008
By measuring the electrical transport properties of superconducting NbN quarter-wave resonators in direct contact with a helium bath, we have demonstrated a high-speed and spatially sensitive sensor for the permittivity of helium. In our implementation a

The characteristics and helium generation potential of helium source rocks in the northern Ordos Basin, China

Frontiers in Earth Science
The origin of helium is predominantly governed by helium source rocks, which encompass a spectrum of lithologies, including metamorphic rocks within the basin’s basement, and mudstones, coal, and other rocks in the overlying sedimentary formations.
