Workbook to accompany Chemistry and the Environment: A Chemistry Perspective for discussion of Environmental Issues [first edition]
(OpenStax and University of Winnipeg Library, 2020-09-08)
Spectroscopic Imaging in Art Conservation: A New Tool for Materials Investigations
(The MIT Press, 2003-08-01)
Effect of the tether length upon Truce‐Smiles rearrangement reactions
(John Wiley & Sons, Ltd., 2017-07-07)
This report examines the effect of substrate design upon the Truce‐Smiles rearrangement, an intramolecular nucleophilic aromatic substitution reaction. The length of the molecular spacer that tethers the carbanion nucleophile ...
Phosphorus Release from Unamended and Gypsum- or Biochar-Amended Soils under Simulated Snowmelt and Summer Flooding Conditions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2020-03-30)
Prolonged flooding changes the oxidation–reduction status of soils, often enhancing P release to overlying floodwater. We studied P release from unamended, gypsum-amended, and biochar-amended soils under simulated snowmelt ...
Temperature and freezing effects on phosphorus release from soils to overlying floodwater under flooded-anaerobic conditions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2020-03-30)
Increased phosphorus (P) availability under flooded, anaerobic conditions may accelerate P loss from soils to water bodies. Existing knowledge on P release to floodwater from flooded soils is limited to summer conditions ...
Differential Enantioselective Transformation of Atropisomeric Polychlorinated Biphenyls by Multiple Bacterial Strains with Different Inducing Compounds
(American Society for Microbiology., 2002-11)
Enantioselective biotransformation of polychlorinated biphenyls
(PCBs) has been suggested from studies showing differential
occurrence of PCB enantiomers in environmental samples, including river and riparian biota and ...

Crystal structure and computational study of an oxo-bridged bis-titanium(III) complex
(International Union of Crystallography, 2021-06)
The solid-state structure of the new compound mu-oxido-bis[dichloridotris(tetrahydrofuran-kappa-O)titanium(III)], [Ti2Cl4O(C4H8O)6], at 150 K has been determined. The crystal has monoclinic (C2/c) symmetry and the complex ...
Aggregation of Fine Particles at the Sediment-Water Interface
(American Geophysical Union, 1992-11-15)
The presence of a bottom sediment layer agitated by mechanical stirring or by resident organisma (tubificid oligochaetes) significantly increases the rate at which fine (1 µm) cohesive particles are removed from suspension ...
Mobility of arsenic and vanadium in waterlogged calcareous soils due to addition of zeolite and manganese oxide amendments
(Wiley, 2023-01-17)
Addition of manganese(IV) oxides (MnO2) and zeolite can affect the mobility of As and V in soils due to geochemical changes that have not been studied well in calcareous, flooded soils. This study evaluated the mobility ...
