Exploring Acrylic Acid as an Oxirane Nucleophile: Direct Access to Poly(β‐Hydroxy Acrylates)

ChemSusChem, EarlyView.
Within, we present a scalable, solvent‐free route to β‐hydroxy acrylate monomers using acrylic acid (AA) as a nucleophile with various oxiranes. Once polymerized, the resulting polymers are optically transparent, thermally stable, and range from brittle to ductile. This straightforward method underscores AA's potential in sustainable, bio‐based polymer

Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

The Depositional Record, EarlyView.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.

Post-translational modifications of pyruvate dehydrogenase complex in cardiovascular disease

iScience
Summary: Pyruvate dehydrogenase complex (PDC) is a crucial enzyme that connects glycolysis and the tricarboxylic acid (TCA) cycle pathway. It plays an essential role in regulating glucose metabolism for energy production by catalyzing the oxidative ...

Characterising a New Cannabis Trend: Extensive Analysis of Semi‐Synthetic Cannabinoid‐Containing Seizures From Germany

Drug Testing and Analysis, EarlyView.
A LC–MS/MS method has been validated for analysis of semi‐synthetic cannabinoids (SSC) and selected phytocannabinoids in seizures. Further SSC‐derivatives were implemented into the method for qualitative detection. The methodology was applied to a sample collective (n = 80) including cannabis flowers, resins, edibles and vape liquids.

Infant Death due to Cannabis Ingestion

Drug Testing and Analysis, EarlyView.
ABSTRACT A child died in the emergency room of a local hospital a few hours after ingesting a substance the color of cork and the consistency of earth. At home, a modest amount of resinous substance was found. At the hospital, the child exhibited alterations in walking, balance, and consciousness.

Toward a Cannabis Terroir: Untargeted Metabolomic Profiling of Authentic Samples Using Gas Chromatography–High‐Resolution Mass Spectrometry (GC‐HRMS) and Liquid Chromatography–High‐Resolution Tandem Mass Spectrometry (LC‐HRMS/MS)

Drug Testing and Analysis, EarlyView.
This study developed a comprehensive metabolomics workflow using GC‐HRMS and LC‐HRMS/MS and analyzed 35 CBD‐type cannabis flowers grown under varying conditions. Key discriminative compounds enabled classification by chemical phenotype and cultivation environment. The results showed that environmental factors influence chemical profiles, supporting the
