Symmetry-Induced Singlet-Triplet Inversions in Non-Alternant Hydrocarbons

Marc Hamilton Folkmann Garner, Anne-Clémence Corminboeuf, Jacob Terence Blaskovits

Molecules with inversion of the singlet and triplet excited-state energies are highly promising for the development of organic light-emitting diodes (OLEDs). To date, azaphenalenes are the only class of molecules where these inversions have been identified ...

Organic Contaminant Abatement in Reclaimed Water by UV/H2O2 and a Combined Process Consisting of O-3/H2O2 Followed by UV/H2O2: Prediction of Abatement Efficiency, Energy Consumption, and Byproduct Formation

Urs von Gunten, Minju Lee, Yun Ho Lee, Silvio Canonica

UV/H2O2 processes can be applied to improve the quality of effluents from municipal wastewater treatment plants by attenuating trace organic contaminants (micropollutants). This study presents a kinetic model based on UV photolysis parameters, including UV ...

An Internal Fluorescent Probe Based on Anthracene to Evaluate Cation-Anion Interactions in Imidazolium Salts

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Christian Hartinger, Wee Han Ang, Xuemei Yang

A series of fluorescent imidazolium-based salts contg. the cation [AnCH2MeIm]+ (in which An=anthracene and Im=the imidazolium cation) with Cl-, BF4-, PF6-, SO3CF3-, [N(CN)2]-, [N(SO2CF3)2]-, or PhBF3- anions have been prepd. and characterized. X-ray diffra ...

Advanced oxidation of the surfactant SDBS by means of hydroxyl and sulphate radicals

Urs von Gunten, Silvio Canonica

The objective of the present study was to characterize the removal of the model surfactant sodium dodecylbenzene sulfonate (SDBS) from waters using several radical-based water treatment processes. Fenton's reagent has shown high efficacy in surfactant degr ...

Experiments and modeling of phenanthrene biodegradation in the aqueous phase by a mixed culture

David Andrew Barry, Jiangyan Yang

Pollution by polycyclic aromatic hydrocarbons (PAHs) is widespread due to unsuitable disposal of industrial waste. They are mostly defined as priority pollutants by environmental protection authorities worldwide. Phenanthrene, a typical PAH, was selected a ...

Alkali-Methanol-Anthraquinone pulping of Miscanthus x giganteus for thermoplastic composite reinforcement

Yves Leterrier

The potential of pulp fiberreinforced thermoplastics is currently not fully explored in composites. One of the main reasons is that pulp fibers are extracted for the use in papermaking and are thus not optimized for use as reinforcements in thermoplastics ...

Effect-directed identification of oxygen and sulfur heterocycles as major polycyclic aromatic cytochrome P4501A-Inducers in a contaminated sediment

Kristin Schirmer

Heterocyclic polyaromatic compounds, including dinaphthofurans, 2-(2-naphthalenyl)benzothiophene, methylated chrysene, and benz[a]anthracene, were identified and confirmed as major cytochrome P4501A (CYP1A)-inducing compounds in a contaminated sediment clo ...
