Exploring helium retention from technical materials: Development and investigation

Nuclear Engineering and Technology
Materials used to study nuclear fusion can retain atmospheric helium unless pretreated before an experiment. Understanding helium outgassing is important for accurate diagnostics in experiments surrounding nuclear fusion.

The Great Escape II: Exoplanet Ejection from Dying Multiple Star Systems

, 2012
Extrasolar planets and belts of debris orbiting post-main-sequence single stars may become unbound as the evolving star loses mass. In multiple star systems, the presence or co-evolution of the additional stars can significantly complicate the prospects ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Effects of Molecular Designs and Double‐Network Morphologies for Bioadhesive Semiconductors

Advanced Functional Materials, EarlyView.
This study establishes molecular‐to‐mesoscale design rules for bioadhesive semiconducting polymers (BASCs). It identifies how side‐chain length, double‐network formation, and film thickness modulate adhesion strength and electronic performance, providing insight into the rational design of intrinsically adhesive semiconductors for stable and efficient ...

Simulation of helium concentration effects on divertor plasma detachment, helium exhaust, and tungsten sputtering via SOLPS-ITER

Nuclear Fusion
As an unavoidable byproduct of deuterium–tritium fusion, helium (He), if uncontrolled, accumulates in core plasma and degrades reactor performance. Furthermore, the presence of helium impurities can have a significant impact on the boundary plasma.

From source to sink in central Gondwana: Exhumation of the Precambrian basement rocks of Tanzania and sediment accumulation in the adjacent Congo basin [PDF]

, 2016
Apatite fission track (AFT) and (U-Th)/He (AHe) thermochronometry data are reported and used to unravel the exhumation history of crystalline basement rocks from the elevated (>1000 m above sea level) but low-relief Tanzanian Craton.

Geochemical analysis of Cenozoic fossil conifers at high latitudes: Implications for molecular preservation and environmental change [PDF]

, 2010
Fossil materials record ancient life and their adapted environment. Arctic plant fossils are critical for our understanding of the Earth’s paleoenvironment when high latitudes were under ice-free conditions.
