A New High‐Pressure Polymorph of MgTe2O5 with a Unique Crystal Structure

European Journal of Inorganic Chemistry, Volume 29, Issue 26, 16 September 2026.
MgTe2O5 synthesized under special high‐pressure/high‐temperature conditions of 8 GPa and 800 °C exhibits a unique crystal structure consisting of fused sechser rings built from pseudooctahedral [TeO5]6– and trigonal‐pyramidal [TeO3]2– units. The single‐crystal structure and temperature‐dependent powder diffraction data are presented.

Genetic and Morphological Diversity of Microsorum Link emend. Ching (Polypodiaceae) in Niue Confirms Three Indigenous Species

New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
We present a taxonomic appraisal of Microsorum in Niue using chloroplast (rbcL, rps4 + rps4‐trnS, trnL + trnL‐trnF) and nuclear (gapCp) DNA sequence data obtained from 25 samples along with an assessment of morphological characters and the habitats occupied.

An Examination of Cultural Transformation in Türkiye After 1980 in the Context of “Neoliberal Governmentality”

Sociology Lens, Volume 39, Issue 3, Page 522-542, September 2026.
ABSTRACT The January 24 Decisions of 1980 and the subsequent Özal era marked a profound rupture, carrying Türkiye from an import substitution economy to an outward‐oriented, “free‐market” order. Drawing on Michel Foucault's concept of neoliberal governmentality, this study conducts a qualitative, interpretivist discourse analysis of Turgut Özal's ...

Deciphering unusually large modulations in two related organic hydroxy channel structures

Acta Crystallographica Section B, Volume 82, Issue 4, Page 375-390, August 2026.
Two related organic hydroxy‐channel compounds are shown to have unusually large structural modulations.The incommensurately modulated structures of two related organic hydroxy‐channel compounds [(R)‐1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐(octan‐2‐yl)urea, 1; 1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐octylurea, 2] have been determined and compared to the structure of a ...

Effect of molecular perturbation on cocrystal formation: theophylline and its 8‐halo analogues with flavonoids

Acta Crystallographica Section C, Volume 82, Issue 8, Page 414-426, August 2026.
The tendency for alkaloid–flavonoid cocrystal formation is found to be markedly different for theophylline (Tph) compared to its 8‐halo analogues. Through screening with 13 common flavonoids, Tph is found to form cocrystals with six flavonoids, whereas 8‐Cl‐Tph and 8‐Br‐Tph each form cocrystals with just two, myricetin and kaempferol.
