The Density of Liquid FeO and the Oxygen Contents of the Cores of Earth and Mars

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Oxygen is a possible light element in the cores of Earth and Mars. Its effect on the density and elastic properties of liquid iron is, therefore, important for estimating its abundance in planetary cores, from which conditions of core‐mantle equilibration could be constrained.

Photoionization of resonantly driven atomic states by an extreme ultraviolet-free-electron laser: intensity dependence and renormalization of Rabi frequencies

New Journal of Physics, 2013
We analyze theoretically the high intensity photoionization dynamics of a system with two atomic states resonantly coupled by coherent extreme ultraviolet laser radiation that also gives rise to the ionization.

Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Magmatic intrusion and volcanic deformation are traditionally approximated with an inflating cavity in an elastic halfspace. Various analytical models predict surface displacement as a function of pressure or volume change, depth, and elastic crustal properties.

Size matters for nonlinear (protein) wave patterns

New Journal of Physics, 2018
Pattern formation and selection are fundamental, omnipresent principles in nature—from small cells up to geological scales. In E. coli bacteria, for example, self-organized pole-to-pole oscillations of Min proteins—resembling a short standing wave—ensure

Single-catalyst high-weight% hydrogen storage in an N-heterocycle synthesized from lignin hydrogenolysis products and ammonia

Nature Communications, 2016
Energy storage and biomass utilization are two major challenges for sustainability. Here the authors use a major lignin hydrogenolysis product for the synthesis of an N-heterocycle and develop a bimetallic catalyst for repeated hydrogenation ...

Opening the black box: in situ imaging of arbuscular mycorrhizal fungal structures in soil using synchrotron‐based micro‐CT

New Phytologist, Volume 251, Issue 6, Page 3687-3702, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) contribute to plant nutrient and water uptake via their extraradical hyphal networks. However, in situ methodologies to quantify architectural and morphological traits of these networks in soil are largely lacking, limiting our understanding of AMF‐mediated resource transport.
