Diffusion mechanisms of coal-measure helium and their implications for helium accumulation: A case study of the Taiyuan Formation, northern Qinshui Basin, China

Meitian dizhi yu kantan
ObjectiveThe global helium-rich gas reservoirs are dominated by conventional natural gas reservoirs. In recent years, helium-bearing natural gas has been discovered in the Carboniferous-Permian coal measures in the Ordos Basin and surrounding regions ...

Controlled Formation of Skyrmion Bags

Advanced Materials, EarlyView.
This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

Characteristics of rare gas isotopes and main controlling factors of helium enrichment in the northern margin of the Qaidam Basin, China

Journal of Natural Gas Geoscience, 2020
Based on the study of the geological background, it is considered that the main factors affecting helium enrichment in the northern margin of the Qaidam Basin (NMQB) are widely distributed rock masses, developed fractures, groundwater system, and more ...

Covalent Surface Modification of Hydrophobic Alkoxides on Ti3C2Tx MXene Nanosheets Toward Amphiphilic and Electrically Conductive Inks

Advanced Materials, EarlyView.
Electrically conductive and amphiphilic MXene inks are achieved by surface modification of sodium alkoxides, where surface‐modified MXenes are dispersible both in water and in non‐polar solvents such as toluene. Alkoxide‐functionalized MXenes also show enhanced environmental stability compared to pristine MXene, leading to higher electrical ...

Sequestration of noble gases in giant planet interiors

, 2010
The Galileo probe showed that Jupiter's atmosphere is severely depleted in neon compared to protosolar values. We show, via ab initio simulations of the partitioning of neon between hydrogen and helium phases, that the observed depletion can be explained

Hydrodynamics in a pressurized cocurrent gas-liquid trickle-bed reactor [PDF]

, 1991
The influence of gas density on total external liquid hold-up, pressure drop and gas-liquid interfacial area, under trickle-flow conditions, and the transition to pulse flow have been investigated with nitrogen or helium as the gas phase up to 7.5 MPa ...

Biocompatible Porphyrin Derivatives Electron Beam and Extreme Ultraviolet Photoresists: High Resolution and High Etch Resistance

Advanced Materials Interfaces, EarlyView.
Porphyrin derivatives are introduced for electron beams and extreme ultraviolet lithography. The lithographic performance of the novel CuTP‐4Epoxy photoresist is excellent, with a resolution of 18 nm in EBL and 20 nm in EUVL, and the photoresist also exhibits high etch resistance.
