The terpyridine anthracene ligand was synthesized and characterized. is a ratiometric fluorescent probe for Cd(2+) with a recognition mechanism based on intramolecular charge transfer (ICT). An complex was isolated, and its structure was established using single-crystal XRD. The complex was able to serve as a novel reversible chemosensing ensemble to allow ratiometric response to pyrophosphate ...

Background and purpose: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental pollutants in soils and sediments that causes concern because of their toxic, mutagenic and carcinogenic effects. The purpose of this study was to determine the feasibility of utilizing poultry manure as a co-substrate to enhance the bioremediation of phenanthrene and anthracene in contaminated soil. ...

The study was aimed to determine the chronic toxicity of Polynuclear aromatic hydrocarbon – Anthracene in response to pigments and metabolic study on three different cyanobacterial species such as Synechocystis sp., Anabaena fertilissima, and Nostoc muscorum. Test organisms were treated at different doses and encountered LC50/Mean Lethal Concentration (at which 50% lethality/ growth reduction o...

In this study, light-emitting diodes (LEDs) used as secure, low-cost and possessing long emission wavelengths irradiation sources were applied in photopolymerization. Seven novel anthracene derivatives (noted A1-A7) proposed evaluated photosensitive systems. Three of them never synthesized before (A1, A2 A7) the other fields. Due to in-silico design molecular structure by modeling, chalcone-ant...

Glass wool was substituted for anthracene in glass cartridges designed for the collection of methylated fatty acids in the effluent stream from a gas-liquid chromatograph. Inexpensive cartridges that gave the same results as those filled with anthracene were obtained.

Biotechnologies based on microbial species capable of destroying harmful pollutants are a successful way to solve some the most important problems associated with clean environment. The subject investigation is Antarctic fungal strain Aspergillus glaucus AL1. culturing examined was performed 70 mg wet mycelium being inoculated in Czapek Dox liquid medium containing naphthalene, anthracene, or p...

Polycyclic aromatic hydrocarbons are very stable compounds and tend to bioaccumulate in the environment due to their high degree of conjugation and aromaticity. Hydrous pyrolysis is explored as a technique for the treatment of industrial water containing PAH, using anthracene as a model compound. The reactivity of anthracene under a range of temperatures and durations are studied in this paper....

The interaction of dibenz[a,h]anthracene and its ultimate carcinogenic 3,4-diol-1,2-epoxide with lung surfactant phospholipid bilayers was successfully performed using molecular dynamics. The DPPC/DPPG/cholesterol bilayer (64 : 64 : 2) was used as the lung surfactant phospholipid bilayer model and compared with the DPPC bilayer as a reference. Dibenz[a,h]anthracene and its 3,4-diol-1,2-epoxide ...

The in vitro oxidation of the two polycyclic aromatic hydrocarbons anthracene and benzo[a]pyrene, which have ionization potentials of <=7.45 eV, is catalyzed by laccases from Trametes versicolor. Crude laccase preparations were able to oxidize both anthracene and the potent carcinogen benzo[a]pyrene. Oxidation of benzo[a]pyrene was enhanced by the addition of the cooxidant 2,2(prm1)-azinobis(3-...
