Diffusion in Cauchy Elastic Solid [PDF]

open access: yes, 2022
It is commonly accepted that a starting point of the science of diffusion is the phenomenological diffusion equation postulated by German physiologist Adolf Fick inspired by experiments on diffusion by Thomas Graham and Robert Brown.

Diffusion in Metals and Intermetallics: An Overview [PDF]

open access: yes, 2022
After a few remarks about the history of diffusion in solids we remind the reader to some basics of diffusion such as tracer diffusion, interdiffusion, high-diffusivity paths, and basic diffusion mechanism in solids.

Magmatic Triggering of Earthquakes on Distal Faults as a Potential Medium‐Term Warning Signal From Ruapehu Volcano

open access: yesGeophysical Research Letters, 2018
A major eruption sequence of Ruapehu volcano began on 17 September 1995, with only hours of local precursory seismicity. However, from about 10 to 5 months prior to the eruption, an unusually high number of tectonic earthquakes occurred between 15 and 20

Chronotherapy in Hematological Malignancies: Evaluating the Rationale and Evidence

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT Hematological malignancies remain one of the leading causes of morbidity and mortality despite advances in targeted therapies, immunotherapy, and stem cell transplantation. Emerging evidence indicates that treatment efficacy and toxicity depend not only on the choice of therapy but also on its timing relative to the patient's internal ...

Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1763-1787, August 2026.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Plumbing system dynamics during the 2024 paroxysmal sequence at the Voragine crater of Mt. Etna volcano as revealed by the olivine crystal cargo

open access: yesVolcanica
The sequence of six paroxysmal eruptions that occurred between July and August 2024 at Mt. Etna’s Voragine crater has been investigated in order to constrain the plumbing system dynamics.

Iron‐Silicate Segregation Within a Convecting Magma Ocean via the Multiphase Thermal Lattice Boltzmann Method: Implication on Iron‐Silicate Mixing

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract During the late stages of planetary accretion, large differentiated impactors interacted with the Earth's magma ocean, producing clouds of iron droplets that sank and mixed with silicates. Using a novel fluid‐dynamic approach combining the Thermal and Rothman‐Keller multiphase Lattice Boltzmann Methods, we modeled the segregation of impactor ...

A Phase Field Model to Describe the Behavior of Volcanic Crystals

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT In this proceeding, a phase‐field model to describe the evolution of size, shape, and composition of volcanic crystals is introduced. It is built on top of an existing model for idealized spherical crystals but uses the phase‐field approach to investigate arbitrary initial shapes and considers the diffusion of diffusion elements as well as ...

An interdisciplinary approach to the pre- and syn-eruptive magma dynamics during the Tajogaite monogenetic eruption (La Palma, 2021)

open access: yesFrontiers in Earth Science
The 2021 Tajogaite eruption (La Palma, Canary Islands) provides a unique opportunity to investigate magma dynamics in magmatic systems where developed and monogenetic volcanoes coexist.

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...
