Cassini observations of ion and electron beams at Saturn and their relationship to infrared auroral arcs [PDF]

, 2012
[1] We present Cassini Visual and Infrared Mapping Spectrometer observations of infrared auroral emissions from the noon sector of Saturn's ionosphere revealing multiple intense auroral arcs separated by dark regions poleward of the main oval.

Design considerations for the use of laser-plasma accelerators for advanced space radiation studies [PDF]

, 2012
We present design considerations for the use of laser-plasma accelerators for mimicking space radiation and testing space-grade electronics. This novel application takes advantage of the inherent ability of laser-plasma accelerators to produce particle ...

Characterization of helium retention in the inhomogeneous co-deposited layers using a long pulse laser induced ablation-quadrupole mass spectroscopy

Nuclear Materials and Energy, 2022
In this work, a spatially lateral-resolved study of the co-deposition of helium (He) and aluminum (Al) in non-uniform layers is carried out by a long pulse Laser-Induced Ablation-Quadrupole Mass Spectrometry (LIA-QMS) approach.

Rational design of 2D organic magnets with giant magnetic anisotropy based on two-coordinate 5d transition metals

APL Materials, 2020
As a new class of single-molecule magnets, two-coordinate complexes of open-shell transition metals are comparatively rare and have attracted interest due to their high degree of coordinative unsaturation.

New fine structure of red luminescence in ZnO observed under exciton resonance excitation

AIP Advances, 2019
A new fine structure of red luminescence (RL) was observed in unintentionally doped ZnO at low temperature. The new RL was demonstrated to be different from the one assigned to Fe3+ center by Heitz et al and visible only under the excitation of light ...
