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).

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?
Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs
Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable
