Mechanism of Selective Arsenic Purification via Reductive Vacuum Sublimation: From Oxygenated Crude Arsenic to High‐Purity Arsenic

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Arsenic presents a critical duality as both a hazardous environmental pollutant and an indispensable material for advanced semiconductor technologies. This study proposes an integrated reductive vacuum sublimation strategy, assisted by carbon and lead additives, to purify crude arsenic containing high oxygen (7.4%) and antimony (1326 mg kg−1).

Standardized Elemental Composition Analysis of Graphene‐Related 2D Materials (GR2M) With SEM/EDS and XPS Works Reliably

Small, Volume 22, Issue 25, 4 May 2026.
The elemental composition of a series of laboratory graphene oxide and reduced graphene oxide materials and a commercial graphene oxide material of high quality is analyzed with the standardless SEM/EDS quantification. XPS is used as a reference method.

Dual Cluster‐Surface Click Chemistries on Silver Nanoclusters

Small Science, Volume 6, Issue 5, May 2026.
In this report, two new structures of clickable anion templated silver nanoclusters (NCs) equipped with azide functional groups capable of cluster surface click reactions are described. It is demonstrated for the first time the Staudinger–Bertozzi ligation and dual click reactions Staudinger–Bertozzi ligation‐strain‐promoted azide–alkyne cycloadditions

Preservation and palaeobiogeography of dinosaur eggs from the Dadaepo Formation (Upper Cretaceous: Cenomanian), Korea

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dinosaur eggs were recovered from the Dadaepo Basin in Busan (south‐east Korea), which is early Late Cretaceous in age and is close to Japan, but the eggs have not been studied. Among East Asian egg‐bearing basins, the Dadaepo Basin is characterized by exceptionally high thermal maturity (c.

Weakening Processes in Carbonate‐Hosted Faults: Phyllosilicate Microlayers and Injections Along the Mattinata Fault (Southern Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Micrometric phyllosilicate films along fault slip surfaces (SSs) can drastically reduce friction, yet they are unexpected in clay‐poor carbonate platforms. We inquire how a major carbonate‐hosted, seismogenic strike‐slip fault can develop weak slip interfaces and undergo dynamic weakening despite an intrinsically strong host rock.
