• Sublethal Concentrations of Silver Nanoparticles Stimulate Biofilm Development

Environmental Science & Technology Letters

Yang and Alvarez

2015 2 (8), pp 221–226

Abstract: Although silver nanoparticles (AgNPs) are used as antimicrobial agents in a wide variety of commercial products, sublethal exposure can counterproductively promote the development of biofilms. We observed by fluorescence microscopy denser biofilm growth ...

• Water Footprint of Hydraulic Fracturing

Kondash and Vengosh

2015 2 (10), pp 276–280

Abstract: We evaluated the overall water footprint of hydraulic fracturing of unconventional shale gas and oil throughout the United States based on integrated data from multiple database sources. We show that between 2005 and 2014, unconventional shale gas and oil ...

• Assessment of Microbial Fuel Cell Configurations and Power Densities

Logan, Wallack, Kim, He, Feng, and Saikaly

2015 2 (8), pp 206–214

Abstract: Different microbial electrochemical technologies are being developed for many diverse applications, including wastewater treatment, biofuel production, water desalination, remote power sources, and biosensors. Current and energy densities will always be ...

• Measurement and Modeling of U(IV) Adsorption to Metal Oxide Minerals

Wang, Ulrich, Pan, and Giammar

2015 2 (8), pp 227–232

Abstract: Chemical or biological reduction of U(VI) produces a variety of poorly soluble U(IV) species. In addition to uraninite (UO2) and biomass-associated noncrystalline U(IV), recent research has found adsorbed U(IV) species on mineral surfaces. To build on ...

• Prospects for Biological Nitrogen Removal from Anaerobic Effluents during Mainstream Wastewater Treatment

Delgado Vela, Stadler, Martin, Raskin, Bott, and Love

2015 2 (9), pp 234–244

Abstract: Growing interest in the anaerobic treatment of domestic wastewater requires a parallel focus on developing downstream technologies that address nitrogen pollution, especially for treatment systems located in eutrophication-impacted watersheds. Anaerobic ...

• Use of Stable Isotope Signatures to Determine Mercury Sources in the Great Lakes

Lepak, Yin, Krabbenhoft, Ogorek, DeWild, Holsen, and Hurley

2015 2 (12), pp 335–341

Abstract: Sources of mercury (Hg) in Great Lakes sediments were assessed with stable Hg isotope ratios using multicollector inductively coupled plasma mass spectrometry. An isotopic mixing model based on mass-dependent (MDF) and mass-independent fractionation (MIF) ...
