Unearthing the shadows of history: Chemical traces of Second World War atrocities in the Szpęgawski Forest and Death Valley, Poland

open access: yesArchaeometry, Volume 67, Issue 2, Page 424-438, April 2025.
Abstract This article presents the results of analyses of the chemical composition of organic matter and the occurrence of characteristic geochemical and biochemical markers in 17 samples collected from the Second World War mass graves excavated in the Szpęgawski Forest and Death Valley, Poland. The results show that attempts to cover up mass crimes by

A Stable Carbon‐Centered Radical Showing Six Amphoteric Redox States

open access: yesChemistry – A European Journal, Volume 31, Issue 6, January 27, 2025.
A fully conjugated system built by alternate fusion of four benzene and three cyclopentadiene rings is a further rare example of an air‐ and moisture‐stable carbon‐centered hydrocarbon radical. It was synthesized by double ortho fusion and was extensively characterized by spectroscopic and computational methods.

Development of Continuous‐Flow Reactions for the Synthesis of Anti‐Alzheimer Drug Memantine

open access: yesChemistry – A European Journal, Volume 31, Issue 5, January 22, 2025.
Memantine hydrochloride, an NMDA receptor antagonist used in Alzheimer's treatment, features an adamantane core with a bridgehead amino group. Its synthesis from acenaphthene involves hydrogenation, skeletal rearrangement, nitration, and reduction. Continuous‐flow reactions were explored for each step to develop a continuous manufacturing process for ...

Ultrasound-Assisted Dispersive Liquid-Liquid Microextraction Combined with Low Solvent Consumption for Determination of Polycyclic Aromatic Hydrocarbons in Seawater by GC-MS

open access: yes, 2011
Ultrasound-assisted dispersive liquid-liquid microextraction (USA-DLLME) with low solvent consumption was demonstrated for gas chromatography-mass spectrometry (GC-MS) determination of 16 typical polycyclic aromatic hydrocarbons (PAHs) in seawater ...

Tracing PAHs in Indoor Dusts as Thirdhand Smoke: The Association With Sick Building Syndrome (SBS) and Probabilistic Human Risk Assessment

open access: yesIndoor Air, Volume 2025, Issue 1, 2025.
Tobacco smoke is a significant contributor to indoor air pollution and poses serious health risks. This study surveyed the levels of polycyclic aromatic hydrocarbons (PAHs) in smoker household dust and the association between PAHs in dust and symptoms of sick building syndrome (SBS).

A styrene based water soluble polymer as a reaction medium for photodimerization of aromatic hydrocarbons in water

open access: yes, 2007
A styrene based water soluble polymer (polymer-A) has been explored as a host for solubilizing otherwise insoluble aromatic hydrocarbons in water. The increased local concentration of encapsulated aromatic hydrocarbons within the hydrophobic pockets of ...
