Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, Volume 68, Issue 3, Page 298-310, June 2026.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Synthesis of a π‐Extended Phenazine Diimide Derivative and Characterization of Its Closed‐Shell Reduced States

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...

Mechanochromism of Glassy Polymers Enabled by a Loop‐Forming Supramolecular Mechanophore

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
The supramolecular mechanophore LOOP is covalently introduced into glassy polymers, capable of reporting force‐induced pre‐failure damage and local fracture events in polymer glasses. Under different mechanical deformation modes, including grinding, tensile stretching, and scratching, LOOP probes irreversible events in polymer glasses through a ...

Degradation of Blue MR‐TADF OLEDs: Host‐dependent Effects of mCBP and MADN Revealed by Fragmentation Profiling

Advanced Optical Materials, Volume 14, Issue 17, 8 May 2026.
Degradation in blue MR‐TADF OLEDs originates from high triplet density caused by slow RISC. LDI‐TOF MS directly detects host‐ and emitter‐derived fragments, providing molecular insight into how triplet accumulation drives degradation in the emissive layer. ABSTRACT Blue organic light‐emitting diodes (OLEDs) employing multi‐resonance thermally activated
