Pressure Response of Crystalline Fluoranthene Probed by Raman Spectroscopy

Crystals
The pressure response and structural stability of fluoranthene crystals up to 8 GPa are investigated using Raman spectroscopy. The vast majority of the Raman peaks upshift with pressure, either sublinearly (intermolecular modes) or quasilinearly ...

Orientation of Disubstituted Fluoranthene Derivatives [PDF]

Nature, 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 ...

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

The Use of the Marine Microalga Tisochrysis lutea (T-iso) in Standard Toxicity Tests; Comparative Sensitivity With Other Test Species

Frontiers in Marine Science, 2019
The marine flagellate Tisochrysis lutea (T-iso), with a global distribution, is one of the most common microalgae used as natural food in aquaculture. In recent years T-iso has also been increasingly used in toxicity testing, although it is not included ...

Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Phenyl-cyclopentadienyl rule

Macedonian Journal of Chemistry and Chemical Engineering, 2012
Within a systematic study of cyclic conjugation in the benzo-annelated derivatives of acenaphthylene and fluoranthene, a general regularity was discovered, named phenyl-cyclopentadienyl rule (PCP rule).

Kekulé Structures in Fluoranthenes

Zeitschrift für Naturforschung A, 2010
Fluoranthenes are polycyclic conjugated molecules consisting of two benzenoid fragments, connected by two carbon-carbon bonds so as to form a five-membered ring. Fluoranthenes possessing Kekul´e structures are classified into three types, depending on the nature of the two carbon-carbon bonds connecting the two benzenoid fragments.

Climatic, Socioecological and Environmental Determinants of Aedes spp. Dynamics at the Community Interface: A Systematic Review With Reflections From a One Health Perspective

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background and Objectives Mosquitoes of the genus Aedes, including but not limited to Aedes aegypti, are major vectors of arboviruses such as dengue, Zika and other related diseases. Their global expansion is driven by climate change, globalisation, urbanisation and human mobility.
