Biota-sediment accumulation factors (BSAF) were calculated for Diporeia spp. and oligochaete worms exposed to polychlorinated biphenyls (PCBs) and polycyclic aromatic... -
Development of Chiral Nucleophilic Pyridine Catalysts: Applications in Asymm...
TADMAP (1a), a new chiral DMAP catalyst, has been designed to place a C(3)-benzylic trityl group over one face of the pyridine ring, while a C(3)-benzylic acetoxy group creates... -
Highly selective cobalt-catalyzed hydrovinylation of styrene
: The hydrovinylation reaction is a codimerization of a 1,3-diene or vinyl arene and ethene with great potential for fine chemicals and pharmaceuticals. For the first time,... -
Modulation of T2 Relaxation Time by Light-Induced, Reversible Aggregation of ...
A reversible T2 contrast agent consisting of cross-linked anionic dextran coated iron oxide nanoparticles covalently coupled to a light-sensitive spiropyran (SP)/merocyanine... -
Indicators for the Exposure Assessment of Transformation Products of Organic ...
Environmental transformation products of organic micropollutants have the potential to be similarly or even more mobile, persistent, or toxic than their parent compounds. They... -
Including sorption to black carbon in modelling bioaccumulation of polycyclic...
Model estimations of bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) have been higher than field or laboratory data. This has been explained by strong sorption to... -
Harmonic Analysis of Environmental Time Series with Missing Data or Irregular...
The Lomb periodogram and discrete Fourier transform are described and applied to harmonic analysis of two typical data sets, one air quality time series and one water quality... -
Emission Rates of Particulate Matter and Elemental and Organic Carbon from In...
Elemental carbon (EC), organic carbon (OC), and particulate matter (PM) emission rates are reported for a number of heavy heavy-duty diesel trucks (HHDDTs) and back-up... -
