Novel Approaches to Porous Material Discovery

Creator:: Sturluson, Arni
Abstract:: Uses for materials with a large surface area and high porosity have grown sig-niﬁcantly in recent years. Porous materials have found usage in applications such as separation, gas storage, sensing, puriﬁcation and more, prompting researchers to ﬁnd and discover numerous new porous materials to suit a speciﬁc purpose. Hundreds of...

Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

Creator:: Mustafa, Nizar Ahmad
Abstract:: Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...

Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:: Michalsen, Mandy M.
Abstract:: Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

Mathematical and Experimental Approaches for Designing Less Toxic Cryopreservation Methods

Creator:: Warner, Ross M.
Abstract:: Successful cryopreservation of all biological specimens would have an untold positive impact on medicine and scientific research. However, cryopreservation of the most complex biological specimens, such as tissues and organs, remains elusive. Vitrification, or ice-free cryopreservation, is promising for cryopreservation of complex specimens. The biggest challenge, though, is the toxicity...

Nanotechnology for solar module applications : zinc oxide nanostructures and anti-reflective coating modeling, deposition, analysis, and model fitting

Creator:: Han, Katherine M.
Abstract:: To become a competitor for fossil fuels such as coal, solar installations will need to be produced and installed at a price equal to or below grid parity. This price can be approached by either reducing the overall system cost or increasing system efficiency. The focus of this paper is...

Solution of the 2D quasi-diffusion low-order equations using a coupled nodal/finite volume discretization in Cartesian and hexagonal geometry

Creator:: Nes, Razvan
Abstract:: An important improvement in the area of reactor core neutronic modeling is the development and use of the methods based on "quasi-diffusion" (QD) low-order equations. This family of methods takes into account the transport exactly using "functionals" computed by solving transport equations, and is amenable to solution with a variety...

Measurement of Gas Exchange, Stream Metabolism, and Carbon Fluxes of Headwater Streams

Creator:: Pennington, Robert S.
Abstract:: Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...

Thermodynamic correction for salts in variably saturated porous media

Creator:: Burns, Erick R.
Abstract:: Using thermodynamic principles, the general relationship describing the equilibrium vapor content in the gas phase above a saline liquid and across a curved liquid-gas interface is developed. Since high salt concentration also affects the intensive and extensive liquid properties, it is also necessary to account for these effects in liquid...

Flow processes in the dry regime : the effect on capillary barrier performance

Creator:: Jansik, Danielle P.
Abstract:: Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...

A Graph Grammar Representation of Metal-Organic Frameworks for Computational Synthesis and Exploration

Creator:: Geringer, Mark K.
Abstract:: In this work, metal-organic frameworks (MOFs) are computationally represented, generated, and evaluated. The organic linker molecules are represented as graphs and use graph grammars where the atoms are represented by nodes and the bonds are represented by arcs. The grammar rules that dictate the graph generation process work on the...
