Vehicle Fires: Significant Fire Hazard in Transportation Infrastructure

open access: yesFire and Materials, Volume 50, Issue 8, Page 927-940, December 2026.
ABSTRACT Vehicle flammability poses a critical threat to transportation infrastructure, with recent fires in depots, tunnels, and car parks highlighting systemic vulnerabilities. These incidents often result in the total loss of vehicles and buildings, revealing the inadequacy of current fire safety standards for vehicle materials.

Spatial Distribution of Return Flows Occurrence in the Venusian Magnetotail and Its Dependence on Upstream Conditions

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Venus‐ward return flow can significantly influence ion escape from Venus and may therefore play an important role in atmospheric evolution. However, the mechanism driving return flow remains under debate. Here, we investigate the occurrence rate and spatial distribution of ion return flows in the Venusian induced magnetotail, and their ...

Photoionization of Atoms [PDF]

open access: yes, 1996
This chapter outlines the theory of atomic photoionization, and the dynamics of the photon-atom collision process. Those kinds of electron correlation that are most important in photoionization are emphasized, although many qualitative features can be ...

The Opacity Project: R-Matrix Calculations for Opacities of High-Energy-Density Astrophysical and Laboratory Plasmas

open access: yesAtoms
Accurate determination of opacity is critical for understanding radiation transport in both astrophysical and laboratory plasmas. We employ atomic data from R-Matrix calculations to investigate radiative properties in high-energy-density (HED) plasma ...

Electronic Structure and Electric Dipole Properties of the AgK Molecule: An Adiabatic and Diabatic Study

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 21, November 5, 2026.
Ab initio adiabatic and diabatic calculations reveal the electronic structure of AgK, highlighting strong non‐adiabatic couplings, avoided crossings, and charge‐transfer effects. The resulting diabatic potentials and dipole moments provide benchmark data for spectroscopy and quantum dynamics of cold AgK molecules. ABSTRACT An ab initio investigation of

PCI EFFECTS IN INNER-SHELL PHOTOIONIZATION

open access: yes, 1987
The most obvious manifestation of post collision interaction (PCI) in inner shell photoionization concerns the energy exchange between the outgoing photoelectron and Auger electron.

L-Shell Photon Excitation Cross Sections for the Chlorine Isonuclear Sequence Clq+ (q=1−4): An Experimental Study

open access: yesAtoms
We report experimental measurements of the absolute photoionization cross sections for chlorine ions in different stages of ionization, over photon energy ranges corresponding to the L-shell (2s and 2p subshells) excitations.

Tuning Surface Enrichment in Liquid Metal Catalysts: A Combined DFT, ML‐FF, and XPS Study of GaAgPt and GaCuPt

open access: yesChemCatChem, Volume 18, Issue 21, 12 November 2026.
Ternary liquid metal catalysts were investigated using a combined density functional theory (DFT)/machine‐learned force‐field (ML‐FF) and x‐ray photoelectron spectroscopy (XPS) approach. Ag and Cu were added to an alloy of 1 at% Pt in Ga and thereby influenced the surface concentration of the catalytically active Pt. ABSTRACT Liquid metal catalysts are
