Investigation of the In Vitro and In Vivo Metabolism and μ‐Opioid Receptor Affinity of the Nitazene N‐Pyrrolidino Fluetonitazene

open access: yesDrug Testing and Analysis, Volume 18, Issue 8, Page 1097-1113, August 2026.
Eight metabolites for N‐pyrrolidino fluetonitazene were identified in vitro, three of which (M2, M6 and M8) were present in an authentic urine sample. M2 was the most abundant in vivo metabolite and is a common marker metabolite of nitazepyne‐type substances.

Optimisation of Electrokinetic Extraction System: Colourimetric Determination of Copper (II) in Sand Using Polymer Inclusion Membrane

open access: yesELECTROPHORESIS, Volume 47, Issue 8, Page 744-753, August 2026.
Electrokinetic extraction (EKE) allows the direct transfer of heavy metals from soli samples, such as soil and sediment, into a polymer inclusion membrane (PIM) with a colourimetric detection. This avoids length and complex sampling handling and extraction processes.

Synthesis and Recycling‐on‐Demand of Novel Bio‐Based Poly(Ester‐co‐Acetal)s Designed for Circularity

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Fully bio‐based oligoesters with defined terminal groups are designed and synthesized utilizing solvent‐free melt polycondensation. An effective chain extension reaction transforms oligomers into semi‐crystalline poly(ester‐co‐acetal)s that can be hot‐pressed into foils.

Catechol‐Containing Poly(2‐isopropyl‐2‐oxazoline): Synthesis and Thermoresponsive Behavior in Aqueous Salt Solutions

open access: yesMacromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Polymers carrying catechol groups are interesting mussel‐inspired materials for wet adhesion applications or metal ion complexation for wastewater treatment. Here, catechol‐containing poly(2‐isopropyl‐2‐oxazoline)s were synthesized via microwave‐assisted cationic (co)polymerization and examined with regard to their thermoresponsive LCST behavior in ...

Follicle Size Regulates Cytoplasmic Maturation, Lipid Content, and Embryo Cryosurvival in Bovine Oocytes Matured In‐Vitro

open access: yesMolecular Reproduction and Development, Volume 93, Issue 8, August 2026.
Follicle size modulates bovine oocyte cytoplasmic maturation during IVM. Oocytes from larger follicles exhibit reduced lipid accumulation, fewer transzonal projections, distinct cumulus cell metabolic signaling, and greater embryo cryosurvival, indicating improved cytoplasmic maturation and lipid regulation despite similar developmental rates ...
