Triplet 4‐Nitrenemethyl‐Pyridine‐N‐Oxide: A Model Alkyl Nitrene Isolated in Cryogenic Matrices

Journal of Physical Organic Chemistry, Volume 39, Issue 5, May 2026.
The simplest triplet alkyl nitrene bearing a pyridine‐N‐oxide moiety was generated by direct irradiation (λ > 350 nm) of the corresponding azide in an Ar matrix at 15 K. Quantum tunneling 1,2‐H shift to the corresponding imine is thermodynamically favorable but does not occur due to a high‐energy barrier (~36 kcal mol−1).

In Vitro Metabolism and Analytical Characterization of SLU‐PP‐332 and SLU‐PP‐915: Novel Pan‐ERR Agonists With Doping Potential

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Estrogen‐related receptor (ERR) agonists such as the drug candidates SLU‐PP‐332 and SLU‐PP‐915 are currently being investigated as exercise mimetics, given their ability to trigger human physiological processes similar to those initiated by actual physical activity.

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Divergent Access to Fluorinated Pharmacons From Ethyl Trifluoropyruvate

Advanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.
Fluoro(oxo) functional group diversification is traditionally accomplished through either specialized reagents or nucleophilic trifluoromethylation. Herein is disclosed the use of commercially available building blocks for the synthesis of trifluoromethyl(hydroxy) esters.

Refining Spat‐Collection Practices to Optimise Single‐Seed Spat Production for New Zealand's Greenshell (Perna canaliculus) Mussel Industry

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Mussel aquaculture depends on a consistent spat supply, often sourced from spat‐collection ropes suspended in coastal waters. However, settlement on these ropes can be highly variable due to environmental factors. Therefore, improving spat supply from this source relies on optimising aspects of the process, particularly the timing of ...
