The Transition From Melt Accumulation to Eruption Initiation Recorded by Orthopyroxene Fe‐Mg Diffusion Timescales in Late Holocene Rhyolites, South Sister Volcano, Oregon Cascade Range

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract South Sister volcano, Oregon Cascade Range, USA, has repeatedly erupted rhyolite since ca. 40 ka. The youngest such eruptions are the ca. 2 ka Rock Mesa and Devils Chain rhyolites, erupted several hundred years apart from two multi‐vent complexes separated by 3–6 km. Fe‐Mg interdiffusion models of orthopyroxene rims from both rhyolites produce

Synthesis and Characterization of A3[ReO4][ReO3N] and A′2[ReO3N] (A = Rb, Cs; A′ = K, Cs)

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 17, June 17, 2025.
Various new nitridotrioxidorhenate compounds were successfully obtained via flux syntheses. By employing different equivalents of ammonium salts as a nitrogen source, it is possible to incorporate different amounts of nitrogen into perrhenates. Four new structures namely Rb3[ReO4][ReO3N], Cs3[ReO4][ReO3N], K2[ReO3N], and Cs2[ReO3N]—were elucidated and ...

Assessing UVA and Laser‐Induced Crosslinking via Brillouin Microscopy

open access: yesJournal of Biophotonics, Volume 18, Issue 5, May 2025.
UVA crosslinking is the primary treatment to combat keratoconus. Nevertheless, unwanted side effects and limitations due to nonselective irradiation lead to the investigation of alternative irradiation treatments. This study shows similar changes in the Brillouin frequency shift of corneas crosslinked with UVA irradiation and a NIR femtosecond laser ...
