Acidic microenvironments in waste rock characterized by neutral drainage: Bacteria-mineral interactions at sulfide surfaces
(MDPI, 2014-03-21)Microbial populations and microbe-mineral interactions were examined in waste rock characterized by neutral rock drainage (NRD). Samples of three primary sulfide-bearing waste rock types (i.e., marble-hornfels, intrusive, ... -
Adsorption of (Poly)vanadate onto Ferrihydrite and Hematite: An In Situ ATR–FTIR Study
(American Chemical Society (ACS) Publications, 2020-03-25)Vanadium (V) has been a useful trace metal in describing Earth’s biogeochemical cycling and development of industrial processes; however, V has recently been recognized as a potential contaminant of concern. Although Fe ... -
Alum addition triggers hypoxia in an engineered pit lake
(MDPI, 2022-02-26)Here, we examine the geobiological response to a whole-lake alum (aluminum sulfate) treatment (2016) of Base Mine Lake (BML), the first pilot-scale pit lake established in the Alberta oil sands region. The rationale for ... -
An approach to complex texts in multiple documents
(Digital Studies in the Humanities, 2022)This article describes an approach to the treatment of texts in complex large textual traditions. Editors are interested in the text as it appears line-by-line in each document, and in how the versions of the text differ ... -
Aqueous vanadate removal by iron(II)-bearing phases under anoxic conditions
(American Chemical Society (ACS) Publications, 2020-03-06)Vanadium contamination is a growing environmental hazard worldwide. Aqueous vanadate (HxVVO4(3−x)− (aq)) concentrations are often controlled by surface complexation with metal (oxyhydr)oxides in oxic environments. However, ... -
Aqueous- and solid-phase molybdenum geochemistry of oil sands fluid petroleum coke deposits, Alberta, Canada
(Elsevier, 2018-11-12)Fluid petroleum coke generated at oil sands operations in the Athabasca Oil Sands Region of northern Alberta, Canada, contains elevated concentrations of molybdenum (Mo) and other metals including nickel (Ni) and vanadium ... -
Assessing the oxidation states and structural stability of the Ce analogue of brannerite
(Wiley, 2017)The Ce‐containing analogue of brannerite (ie, UTi2O6) was previously considered to be stoichio- metric (ie, CeTi2O6); however, it has recently been determined that the material is O deficient. This oxygen‐deficient material ... -
Benchmarking multiphysics software for mantle convection
(Elsevier, 2021-09)Numerical simulations are a highly valuable tool for improving our understanding of mantle dynamics. COMSOL Multiphysics® is a commercial software suite designed to numerically model experiments featuring multiple branches ... -
Builder Borders on Aboriginal Lands
(2019)During the nineteenth and early twentieth centuries, the United States and Canada expended significant effort demarcating and enforcing their shared border. The surveying process began in the east, transitioned to the ... -
Chemical mass transport between fluid fine tailings and the overlying water cover of an oil sands end pit lake
(American Geophysical Union, 2017-05-17)Fluid fine tailings (FFT) are a principal by-product of the bitumen extraction process at oil sands mines. Base Mine Lake (BML)—the first full-scale demonstration oil sands end pit lake (EPL)—contains approximately 1.9 3 ... -
Complexity or simplicity? Designing product pictures for advertising in online marketplaces
(Pergamon, 2016-01-31)In online marketplaces, many sellers highlight product and service information directly within product pictures for advertising purposes. Such a strategy increases the visual complexity of the picture and provides more ... -
Connecting Molecular Conformation to Aggregation in P3HT Using Near Edge X-ray Absorption Fine Structure Spectroscopy
(American Chemical Society, 2017-10-11)Carbon 1s Near Edge X-ray Absorption Fine Structure (NEXAFS) and UV-vis spectroscopy are used to examine differences between highly aggregated and poorly aggregated forms of the polymer poly(3-hexylthiophene) (P3HT), based ... -

Design, synthesis, catalytic application, and strategic redispersion of plasmonic silver nanoparticles in ionic liquid media
(Elsevier, 2014)Silver nanoparticles synthesized in tetraalkylphosphonium ionic liquids are found to be excellent catalysts for borohydride-induced reductive degeneration of Eosin-Y, a dye that has been classified as a Class 3 carcinogen ... -
Dissolved selenium(VI) removal by zero-valent iron under oxic conditions: Influence of sulfate and nitrate
(American Chemical Society, 2017-04-17)Dissolved Se(VI) removal by three commercially-available zero-valent irons (ZVIs) was examined in oxic batch experiments under circumneutral pH conditions in the presence and absence of NO3- and SO42-. Environmentally ... -
Does gamification work for boys and girls?: An exploratory study with a virtual learning environment
(ACM New York, NY, USA ©2015, 2015-04-13)The development and use of Virtual Learning Environments (VLE) has increased considerably over the past decades. Following that trend, many research findings have shown the benefits of using VLE during the learning process. ... -
