Sand to Root Transfer of PAHs and PCBs by Carrots Grown on Sand with Pure Substances and Biosolids Amended Sand [PDF]

open access: yes, 2006
A study on behaviour of trace organic compounds (Polycyclic Aromatic Hydrocarbons, PAH, and Polychlorinated Biphenyls, PCB) in a sand-plant system has been carried out, with the reclamation of wastewater treatment plant biosolids for agriculture in mind.

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Evaluation of the effect of flaxseed oil and docosahexaenoic acid on hematological and oxidative stress markers of female Wistar rats with 7, 12‐dimethylbenz[a]anthracene‐induced breast cancer

open access: yesFood Biomacromolecules, EarlyView.
DHA and flaxseed oil reduce tumor sizes, superoxide dismutase activity, malondialdehyde level and increase white blood cells, platelets, serum protein level, glutathione peroxidase, nitric oxide, catalase activities in DMBA‐induced breast cancer in Wistar rats compared to the negative control.

Impact of carwash discharge on stormwater quality (Toulouse, France) [PDF]

open access: yes, 2010
The contribution of discharge from carwashes to pollutant levels in stormwater was evaluated. Five carwashes and two outlets in the city of Toulouse (France) were selected. Water samples were collected from December 2006 to December 2007.

Leveraging Machine Learning to Predict Food Waste Quantity: Focusing on Military Dining Facilities as Large‐Scale Food Service Operations

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Food waste reveals inefficiencies in resource use and contributes significantly to environmental pollution. In the United States, food waste accounts for the majority of total waste, with more than 50 million tons generated annually. In military units that operate large‐scale institutional food‐service facilities and generate significant food ...

Fluorine-Containing Dibenzoanthracene and Benzoperylene-Type Polycyclic Aromatic Hydrocarbons: Synthesis, Structure, and Basic Chemical Properties

open access: yesMolecules, 2018
Intramolecular photocyclization of stilbene derivatives (Mallory reaction) is one of the efficient methods for building polycyclic aromatic hydrocarbon (PAH) frameworks, and is also expected to be applicable to synthesis of fluorine-containing PAHs (F ...

Exploring the possibility of polycyclic aromatic hydrocarbons and fulleranes as the carrier of the 21 micron emission feature

open access: yesFrontiers in Astronomy and Space Sciences
IntroductionThe 21 μm emission feature discovered in a small sample of carbon-rich protoplanetary nebulae has remained unidentified for over 30 years. A dozen of different molecular species (both organics and inorganics) have been proposed as the carrier

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

open access: yesInternational Journal of Cancer, EarlyView.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...
