Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 2, Page 343-359, February 2026.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Steps Towards a Template for Fair Comparisons Between Single‐Use and Reusable Items

open access: yesPackaging Technology and Science, Volume 39, Issue 2, Page 137-159, February 2026.
This paper deals with factors taken up in reuse—single‐use packaging systems comparisons, that are often seen to be missing from LCA studies. The losses and the size of product pool in a reuse system show large effects on the performance of the reuse system and its possible break‐even point.

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.
