Source apportionment of polycyclic aromatic hydrocarbons (PAHs) in small craft harbor (SCH) surficial sediments in Nova Scotia, Canada.

open access: yesScience of the Total Environment, 2019
Multiple source apportionment approaches were employed to investigate PAH sources which contribute to small craft harbor (SCH) sediments in Nova Scotia (NS), Canada. A total of 580 sediment samples were analyzed using PAH diagnostic ratios, Unmix Optimum

Polycyclic aromatic hydrocarbons (PAHs) and their polar derivatives (oxygenated PAHs, azaarenes) in soils along a climosequence in Argentina [PDF]

open access: yes, 2014
We evaluated the effects of soil properties and climate on concentrations of parent and oxygenated polycyclic aromatic compounds (PAHs and OPAHs) and azaarenes (AZAs) in topsoil and subsoil at 20 sites along a 2100-km north (N)–south (S) transect in ...

Polymer Sequence Design of Zwitterionic Polymer/PEDOT:PSS Blend Films for Improved Charge Transport and Stability in Organic Electrochemical Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Solution blending of zwitterionic polymers with PEDOT:PSS provides a simple route to OECT materials with enhanced threshold voltage stability in biologically relevant environments. The polymer sequence alters outer‐domain structure within the preserved PEDOT:PSS framework, thereby tuning charge transport.

Source apportionment of atmospheric PAHs and their toxicity using PMF: Impact of gas/particle partitioning

open access: yes, 2015
24-h PM2.5 samples were simultaneously collected at six sites in a subtropical city of South China during November December, 2009. Particle-phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and organic tracers such as hopanes for vehicular ...

Heavy Metal Contamination: Impacts From Plants to the Food Chain and Eco‐Friendly Amelioration Strategies

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

Axially Chiral Nonalternant Polycyclic Aromatic Hydrocarbon With Consecutive Pentagons Exhibiting Large Spin‐Polarized Current

open access: yesAngewandte Chemie, EarlyView.
Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.

Risk stratification in PAH

open access: yesGlobal Cardiology Science and Practice, 2020
[No abstract. Showing first paragraph of article]Pulmonary arterial hypertension (PAH) is a chronic disease of the pulmonary vasculature characterized by progressive narrowing of the pulmonary arteries leading to increased pulmonary vascular resistance, right heart failure, and ultimately premature death.There has been a significant improvement in the ...
