π‐Expanded Fluoranthenes as Chromophores With Tailored Properties

open access: yesHelvetica Chimica Acta, EarlyView.
A series of π‐expanded fluoranthene scaffolds selectively functionalized with electron donors and acceptors were synthesized. The evolution of the structural, optoelectronic, and redox properties in relation to substitution and cyclization was comprehensively studied both in experiment and in theory. The results identify the compounds as highly tunable

Degradation of Polycyclic Aromatic Hydrocarbons by Moderately Halophilic Bacteria from Luzon Salt Beds

open access: yesJournal of Health and Pollution, 2018
Background. Polycyclic aromatic hydrocarbons (PAHs) are common environmental contaminants which are highly toxic due to their carcinogenic and mutagenic effects.

Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

Orientation of Disubstituted Fluoranthene Derivatives [PDF]

open access: yesNature, 1950
ALTHOUGH fluoranthene is readily attacked by bromine, etc., none of the disubstituted products has been rigidly orientated. Tobler et al.1 obtained a fluoranthene disulphonic acid, which on fusion with alkali followed by oxidation gave a coloured ‘chin-hydronartigen’ compound, and they rightly pointed out that a quinoid product would mean that ...

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...
