Form (III) of artemisinin: discovery and crystallographic characterization of a new high‐pressure polymorph

Acta Crystallographica Section B, Volume 82, Issue 3, Page 316-329, June 2026.
The polymorphic behaviour of the three forms of artemisinin was investigated using single‐crystal X‐ray diffraction in a diamond anvil cell, with notable observation of a pressure‐induced phase transition from form (II) to form (III).Artemisinin (ART) is mainly used for the treatment of malaria and exhibits polymorphism with two known crystalline forms.

Silicon allotropes by large‐volume high‐pressure techniques: crystal growth mechanisms, phase diagrams and hexagonal nanostructured Si‐6H by in situ X‐ray diffraction and computational methods

Acta Crystallographica Section B, Volume 82, Issue 3, Page 280-298, June 2026.
In situ X‐ray diffraction is used for exploring Si crystallography and for studying phase‐transformation mechanisms in elemental Si and Na–Si systems. We present original results of hexagonal silicon, Si‐6H and a critical analysis of the past‐decade discoveries of silicon Si‐4H and Si24 using large‐volume high‐pressure techniques.Metastable allotropes ...

Incommensurate structure of AlPO4‐5 and its stability

Acta Crystallographica Section B, Volume 82, Issue 3, Page 344-351, June 2026.
The incommensurately modulated structure of AlPO4‐5 was elucidated by single‐crystal X‐ray diffraction, revealing correlated rotational displacements of AlO4 and PO4 tetrahedra.The incommensurate structure of AlPO4‐5 and its stability have been investigated in detail.

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, Volume 68, Issue S3, Page S8-S30, June 2026.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

A Framework for Emergency Department–Integrated Hepatitis C Test‐and‐Treat in the United States

Journal of Viral Hepatitis, Volume 33, Issue 6, June 2026.
ABSTRACT Despite the availability of curative, direct‐acting antiviral therapy, hepatitis C virus elimination remains incomplete. Losses across the care cascade continue to limit impact, from initial diagnosis to sustained virologic response. Fewer than 1/3 of individuals ultimately achieve cure. These gaps reflect a delivery system that does not align
