Phthalates and Mixed Alkyl Phthalates Analysis in Plastics Using GC‐MS With Cold EI

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Phthalates are esters of phthalic acid. They are widely used as plasticizers to improve the flexibility, durability, and performance of plastics in a variety of products. However, certain phthalates are associated with significant health risks, including endocrine disruption and reproductive toxicity.

A Perspective of Multi‐Reflecting TOF MS

open access: yesMass Spectrometry Reviews, Volume 45, Issue 3, Page 476-506, May/June 2026.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Strong‐Gradient Diffusion‐Weighted Imaging of Prostate Cancer Using an Inside‐Out Nonlinear Gradient Coil

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2671-2688, May 2026.
ABSTRACT Purpose To demonstrate improved image quality and lesion conspicuity in prostate diffusion‐weighted imaging (DWI) using an inside‐out nonlinear gradient coil that provides locally strong gradients (200–500 500 mT/m) at typical prostate positions.

DEEP‐DISORDER: Motion Correction in 3D MRI via Segment Reconstruction and Registration

open access: yesNMR in Biomedicine, Volume 39, Issue 5, May 2026.
This work presents a retrospective motion correction framework for 3D MRI. A motion‐corrupted acquisition is split into tiny k‐space segments, and for each a neural network reconstructs a rough anatomical image. These reconstructions are aligned using groupwise registration, yielding one set of estimated motion parameters per segment.
