Spectroscopic Reactor for Operando Investigations Made by Additive Manufacturing for High‐Pressure Catalysis Applications

Chemistry–Methods, EarlyView.
A spectroscopic reactor for operando X‐ray studies under high‐pressure conditions is developed and fabricated via additive manufacturing. Its two‐zone design allows independent temperature control and catalyst loading, enabling studies at different conversion levels. A large window permits spatially‐resolved X‐ray analysis.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Identification and Structural Elucidation of a New Synthetic Cannabinoid, MDMB‐5′Br‐PINACA, in Seized Herbal Materials

Drug Testing and Analysis, EarlyView.
MDMB‐5Br‐PINACA, a novel synthetic cannabinoid, was identified and structurally characterized in seized herbal products using GC‐MS, LC‐HRMS, and NMR. The discovery underscores ongoing diversification of SCs and the need for vigilant surveillance.

Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)

Drug Testing and Analysis, EarlyView.
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...
