    Abstract Predicting and elucidating the impacts of materials on human health and the environment is an unending task that has taken on special significance in the context of nanomaterials research over the last two decades. The properties of materials in environmental and physiological media are dynamic, reflecting the complex interactions between materials and these media. This dynamic behavior requires special consideration in the design of databases and data curation that allow for subsequent comparability and interrogation of the data from potentially diverse sources. We present two data processing methods that can be integrated into the experimental process to encourage pre-mediated interoperability of disparate material data: Knowledge Mapping and Instance Mapping. Originally developed as a framework for the NanoInformatics Knowledge Commons (NIKC) database, this architecture and associated methods can be used independently of the NIKC and applied across multiple subfields of nanotechnology and material science.

    Abstract The objective of this study is to assess how method parameters impact the extraction of moderately soluble CuO nanoparticles (NPs) from a standard natural soil (LUFA 2.1) suitable for chemical analysis. The extraction procedure is comprised of three steps: (i) preconditioning the soil to increase the sodium adsorption ratio, (ii) extracting colloids/NPs from the soil matrix using sonication and a dispersing agent, and (iii) separating the dissolved and nanoparticulate CuO fractions using cloud point extraction. Method parameters of the extraction procedure, including sonication, number of extraction cycles, and dispersing agent, were adjusted to achieve the highest extraction of CuO NPs, while minimizing dissolution. The maximum recovery of CuO NPs ranged from 31% to 42% for an amended concentration range of 10-250 mg-Cu (kg soil)

    Abstract Biocides are applied as chemical additives in hydraulic fracturing fluids to control subsurface microbial activity. When biocides are released into the subsurface, their fate is controlled by sorption to solids and heterogeneous electron transfer (redox) reactions at the mineral–fluid interface. The ability to predict whether produced water may contain unreacted biocides, or biocide–mineral transformation products, is relevant for defining optimal produced water treatment and beneficial use approaches. This article reviews major minerals that may impact biocide sorption and reactivity in the Marcellus Shale, with a specific focus on biocide–mineral interactions. The chemical and physical properties of quartz, illite, chlorite, pyrite, calcite and dolomite are presented and their reactions with organic compounds structurally similar to biocides are identified. Oxygen-containing functional groups are common among organic biocides, where the carbonyl (–C=O) substructure is integrated into many biocides. Cationic surfactant biocides are expected to sorb to every mineral. Clays, because of their negative surface charge and comparatively high surface area, make excellent sorbents of positively charged biocides. Sorption to organic matter is expected to be limited due to the very polar groups found in biocides. Pyrite is most likely to cause transformation of biocides due to its ability to reduce halogenated organic compounds and initiate Fenton-like reactions, which generate non-specific hydroxyl radicals that react with biocides. Carbonate minerals may act as potential chemisorption sites for biocides possessing a carbonyl group adjacent to another electronegative group. However, the rapid dissolution of this mineral limits its persistence at the mineral–fluid interface. These potential sorption versus transformation reactions can be applied to predict biocide fate in unconventional oil and gas reservoirs and, where appropriate, other subsurface reservoirs used for energy resource extraction or storage.

    Abstract The objective of this study is to assess how method parameters impact the extraction of moderately soluble CuO nanoparticles (NPs) from a standard natural soil (LUFA 2.1) suitable for chemical analysis. The extraction procedure is comprised of three steps: (i) preconditioning the soil to increase the sodium adsorption ratio, (ii) extracting colloids/NPs from the soil matrix using sonication and a dispersing agent, and (iii) separating the dissolved and nanoparticulate CuO fractions using cloud point extraction. Method parameters of the extraction procedure, including sonication, number of extraction cycles, and dispersing agent, were adjusted to achieve the highest extraction of CuO NPs, while minimizing dissolution. The maximum recovery of CuO NPs ranged from 31% to 42% for an amended concentration range of 10−250 mg-Cu (kg soil)⁻¹ using a preconditioning step to exchange divalent cations for monovalent ions, 0.2% carboxymethyl cellulose (CMC) 700 kg mol–¹ as the dispersing agent, probe sonication for 1 min, 3 extraction cycles, and a 1:10 soil-to-liquid ratio. CuO NPs that are polyvinylpyrrolidone (PVP)-coated with a greater stability against aggregation had significantly higher extractability and dissolution. This procedure is the first to effectively extract moderately soluble NPs from soil and experimentally separate them from their dissolved fraction and can be applied to other moderately soluble metal containing natural, incidental, or engineered NPs in soil.
