Probing the delocalized core-hole via inner-shell excitation in N2

open access: yesNew Journal of Physics, 2022
The dispute about whether the 1 s core-hole is localized on one atom or delocalized over both in a homonuclear diatomic molecule has continued for decades, which has been extensively studied by the photoelectron and electron–ion coincidence ...

On the importance of inner-shell transitions for opacity calculations [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2003
For high temperatures and densities, stellar opacities obtained from the Opacity Project (OP) were smaller than those obtained from the OPAL project. Iglesias and Rogers [Ap.J. v443, 469 (1995)] suggested that the discrepancy was due to the omission by OP of important atomic inner-shell processes, and considered in detail results for a mixture of 6 ...

Toward a post-carbon society: supporting agency for collaborative climate action

open access: yesEcology and Society
Current post-carbon transition trajectories are primarily focused on external solutions, while citizens’ inner lives and roles in collective transformation and system change processes are largely overlooked.

Combined effect of tungsten inert gas welding and roller expansion processes on mechanical and metallurgical characteristics of heat exchanger tube-to-tubesheet joints

open access: yesJournal of Materials Research and Technology, 2022
Tube-to-tubesheet joints are one of the major vulnerable locations prone to cracks in heat exchangers. The manufacturing processes of these joints have an important role in providing structural integrity to the heat exchangers. The main objective of this

Return of 4U 1730–22 after 49 yr Silence: The Outburst Properties Observed by NICER and Insight-HXMT

open access: yesThe Astrophysical Journal Letters, 2022
After 49 yr of quiescence, 4U 1730–22 became active and had two outbursts in 2021 and 2022; the onset and tail of the outbursts were observed by NICER, which give us a peerless opportunity to study the state transition and its underlying mechanism.

Increased susceptibility of striatal mitochondria to calcium-induced permeability transition

open access: yes, 2003
Mitochondria were simultaneously isolated from striatum and cortex of adult rats and compared in functional assays for their sensitivity to calcium activation of the permeability transition.

Two-photon inner-shell transitions in xenon atoms

open access: yesPhysical Review A, 1991
Decay of single-K-shell-vacancy states of xenon atoms by the emission of photon pairs that continuously share the transition energy was studied. The vacancy states were generated by electron-capture decay in $^{131}\mathrm{Cs}$. A pair of high-purity germanium detectors and a fast-slow coincidence system with a (128\ifmmode\times\else\texttimes\fi{}512\

Fe Melting Transition: Electrical Resistivity, Thermal Conductivity, and Heat Flow at the Inner Core Boundaries of Mercury and Ganymede

open access: yesCrystals, 2019
The electrical resistivity and thermal conductivity behavior of Fe at core conditions are important for understanding planetary interior thermal evolution as well as characterizing the generation and sustainability of planetary dynamos.
