Study on Diphenylamine Oxidation by Ozone Using Atmospheric Pressure Chemical Ionization Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Diphenylamine (DPAH) derivatives, widely used as antioxidants, interact with oxygen molecules (or ozone) to form radicals at the amine group. Although the antioxidation mechanism involves radical processes, separating these radicals using chromatography is challenging. Methods Rapid oxidation of DPAH was achieved through ozonation in

A Comparative Study of MALDI MSI Versus DESI MSI Applied to Questioned Document Examination

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale In forensic investigations, questioned document examination (QDE) provides critical information for document authentication and the detection of forgeries. Conventional QDE approaches often require separate analyses of inks and of any potential fingerprints.

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ15N Integrity of Nitrogen‐Poor Samples

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

High‐Resolution LC–MS/MS Characterization of Budmunchiamine‐Type Alkaloids in Albizia niopoides

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Budmunchiamines are macrocyclic spermine alkaloids that constitute a distinctive class of polyamine natural products predominantly found in species of the genus Albizia. Comprehensive characterization of these compounds remains challenging because of their structural diversity and the limited availability of reference standards. This

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, Volume 36, Issue 80, 5 October 2026.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.

MIND diet–related plasma proteins are associated with Alzheimer's disease risk

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Adherence to the Mediterranean–Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay (MIND) diet is associated with reduced dementia risk, but underlying mechanisms remain unclear. METHODS Plasma proteomics (SomaScan 7k) from 206 Indiana Alzheimer's Disease Research Center participants were analyzed ...
