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, EarlyView.
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 ...

Synthesis of Monazite‐Borosilicate Glass Composites by the Ceramic Method

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
A glass‐ceramic composite containing crystallites of La0.5Gd0.5PO4 (monazite) dispersed in a borosilicate glass matrix was synthesized using a one‐step ceramic synthesis method. ABSTRACT Glass‐ceramic composites are promising heterogeneous materials for the immobilization of high‐level nuclear waste.

In Situ Characterization of Lignin Precipitation by Synchrotron Small‐Angle X‐Ray Scattering

open access: yesChemistry–Methods, Volume 6, Issue 7, July 2026.
Small‐angle X‐ray scattering was used to observe the formation of nanoscale lignin structures in situ, when mixing industrial spent liquor and antisolvent. The results showed systematic differences in the size and packing of nanoscale structural units that form larger lignin aggregates and demonstrated the feasibility of the method.

A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

Extraction replica method from thinned transmission electron microscopy samples without floating off carbon films: A case study on reduced activation steel

open access: yesJournal of Microscopy, Volume 303, Issue 1, Page 88-100, July 2026.
Abstract A recipe for producing carbon extraction replicas from twin‐jet electropolished disks is described. This technique allows tracking the analysed region with respect to the bulk sample. An example use of the method as applied to a reduced activation ferritic martensitic (RAFM) steel, ‘UK‐RAFM’, is reported.

Site‐Selective B─H Activation via HAT Toward Xanthyl‐closo‐Carboranes as Bench‐Stable Precursors of Organosulfur Boron Clusters

open access: yesAngewandte Chemie, Volume 138, Issue 24, 8 June 2026.
A light mediated direct regioselective B─H functionalization, via hydrogen atom transfer (HAT), is described. Unexplored xanthyl‐closo‐carboranes as novel bench‐stable and versatile platforms to access sulfur‐containing boron clusters are reported for the first time.

Structural Response of Laser‐Driven Shock Compressed Albite

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Plagioclase records characteristic shock features that constrain meteorite impact conditions, but its phase evolution along the Hugoniot remains unresolved. We investigated shock‐induced phase transition in albite using in situ X‐ray diffraction during laser‐driven shock at 14–66 GPa. Albite retained its crystal structure up to at least 14 GPa
