δ13C and δ15N Values of Residues Provide Insights Into Identification of the Explosive Source

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Postblast analyses of military and terrorist events will benefit from the capacity to learn more about the explosive materials used in an event. Here stable isotope ratio analyses (δ13C, δ15N) can provide additional information to complement identification of the explosive components.

Exploring Passive Permeability Profiles of Cyclic Heptapeptide Chemical Space Uncovers Bioactivity of Mortiamide Scaffold Driven by Colloidal Aggregation

open access: yesChemBioChem, Volume 27, Issue 9, 14 May 2026.
A comprehensive stereochemical and physicochemical survey of cyclic heptapeptide chemical space reveals that the mortiamide natural product scaffold possesses intrinsically low aqueous solubility and forms amyloid‐like fibril aggregates. Multiple orthogonal assays demonstrate that the observed cytotoxicity arises from colloidal aggregation rather than ...

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling

open access: yesAdvanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a

Infertility Risk and Employment History Among US Women: Findings From National Health and Nutrition Examination Survey 2013–2014

open access: yesAmerican Journal of Industrial Medicine, Volume 69, Issue 5, Page 358-371, May 2026.
ABSTRACT Introduction It is well established that exposure to chemical, radiological, and biological hazards in the workplace are infertility risk factors. Although workplace‐specific infertility risks have been documented, the associations between employment history and infertility risk remain largely unexplored.

Color and COD Removal From ECF Effluent by Airlift Reactor With Immobilized Lentinus edodes

open access: yesChemical Engineering &Technology, Volume 49, Issue 5, May 2026.
Airlift bioreactor treating ECF bleaching effluent with Lentinus edodes immobilized on polystyrene fibers achieved up to 48% color and 41% COD removal. Under optimized aeration (300 mL/min) and HRT (78 h) without glucose, COD removal remained stable for 15 days, supporting a low‐input, enzyme‐driven strategy for pulp‐and‐paper wastewater.
