Caxton's Afterlife in Manuscript (c.1475‐c.1500)

Renaissance Studies, Volume 40, Issue 2, Page 274-292, April 2026.
Abstract At least thirty‐five manuscript copies of Caxton's prints have been found so far. This article explores the implications of such manuscript copies of Caxton's prints and, interrupting the linear history of the book, considers Caxton's appeal beyond print in manuscript.

Chlorinated Paracyclophanes: Composition Analysis and Direct Metal‐Free Alkylation with n‐BuLi

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
A transition‐metal‐free alkylation of pseudo‐para dichloro[2.2]paracyclophane (Cl2‐PCP) is reported, utilizing the purified pseudo‐para isomer and n‐butyllithium (BuLi). Optimization with the chelating agent TMEDA and refluxing n‐heptane significantly boosted selectivity and reaction rate, providing the dialkylated product in 22% isolated yield.

Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.

Theoretical and Experimental Investigations of Acetal Formation During the Oxidation of Xylose to Formic Acid Catalysed by H5PV2Mo10O40 in Methanolic‐Aqueous Solution

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
The substrate‐solvent interactions play a major role in the modified OxFA process. Herein, the formation and stability of several reaction intermediates via acetalization depending on solvent composition and reaction conditions is investigated. The BioValCat (Enhanced Biomass Valorization by Engineering of Polyoxometalate Catalysts) project aims at ...
