Fabrication Of High Aspect Ratio Metal Nanotips By Nanosecond Pulse Laser Melting, Bo Cui, Lin Wu, Stephen Y. Chou

Department of Mechanical and Materials Engineering: Faculty Publications

The authors have developed an approach to fabricate sharp and high aspect ratio metal tips using nanosecond pulse laser melting. A quartz wafer covered with a thin chromium (Cr) film was placed on top of a second wafer with a sub-micrometer gap between them and the Cr film facing the second wafer. Then an excimer laser pulse (308 nm wavelength, 20 ns pulse duration) was shone from the back of the quartz wafer and melted the Cr film momentarily (several hundred nanoseconds). It is found that the molten Cr films can self-form discrete metal pillars connecting the two wafers. After …

Control Of The Nanoscale Crystallinity And Phase Separation In Polymer Solar Cells, Chih-Wei Chu, Hoichang Yang, Wei-Jen Hou, Jinsong Huang, Gang Li, Yang Yang

Department of Mechanical and Materials Engineering: Faculty Publications

Grazing-incidence x-ray diffraction and atomic force microscopy were performed on bulk heterojunction regioregular poly(3-hexylthiophene) (RR-P3HT) [6,6]-phenyl-C₇₁-butyric acid methyl esters spin-cast films with different film processing conditions to correlate the crystalline nanostructure of P3HT with the corresponding solar cell performance. The increase in long wavelength absorption for solvent annealed films is related to highly conjugated crystal structure of RR-P3HT phase-separated in the active layer. Upon thermal annealing, the solvent annealed 50-nm-thick device shows high solar cell performance with fill factor up to 73% and power conversion efficiency of 3.80%.

Pavement Quality Indicators Study, Wayne Jensen Ph.D., Cody Kluver

Mid-America Transportation Center: Final Reports and Technical Briefs

The Nebraska Department of Roads (NDOR) conducts annual examinations of the Nebraska’s interstate and federal high-way pavements. During these examinations, numerous indicators of pavement quality are measured directly or are com-piled from parameters recorded by a vehicle passing over the pavement section. Parameters are documented and analyzed for each one-tenth mile segment. A number of pavement sections where innovative features have been incorporated were selected by the NDOR for comparison to nearby conventional pavement sections. This study used data recorded by the NDOR as well as field observations to develop a comparison between two pavement sections, one with innovative fea-tures …

Scale-Dependent Desorption Of Uranium From Contaminated Subsurface Sediments, Chongxuan Liu, John M. Zachara, Nikolla P. Qafoku, Zheming Wang

United States Department of Energy: Publications

Column experiments were performed to investigate the scale-dependent desorption of uranyl [U(VI)] from a contaminated sediment collected from the Hanford 300 Area at the U.S. Department of Energy (DOE) Hanford Site, Washington. The sediment was a coarse-textured alluvial flood deposit containing significant mass percentage of river cobble. U(VI) was, however, only associated with its minor fine-grained (<2 mm) mass fraction. U(VI) desorption was investigated both from the field-textured sediment using a large column (80 cm length by 15 cm inner diameter) and from its <2 mm U(VI)- associated mass fraction using a small column (10 cm length by 3.4 cm inner diameter). Dynamic advection conditions with intermittent flow and stop-flow events of variable durations were employed to investigate U(VI) desorption kinetics and its scale dependence. A multicomponent kinetic model that integrated a distributed rate of mass transfer with surface complexation reactions successfully described U(VI) release from the fine-grained U(VI)-associated materials. The field-textured sediment in the large column displayed dual-domain tracer-dependent mass transfer properties that affected the breakthrough curves of bromide, pentafluorobenzoic acid (PFBA), and tritium. The tritium breakthrough curve showed stronger nonequilibrium behavior than did PFBA and bromide and required a larger immobile porosity to describe. The dual-domain mass transfer properties were then used to scale the kinetic model of U(VI) desorption developed for the fine-grained materials to describe U(VI) release and reactive transport in the field-textured sediment. Numerical simulations indicated that the kinetic model that was integrated with the dual-domain properties determined from tracer PFBA and Br best described the experimental results. The kinetic model without consideration of the dual-domain properties overpredicted effluent U(VI) concentrations, while the model based on tritium mass transfer underpredicted the rate of U(VI) release. Overall, our results indicated that the kinetics of U(VI) release from the field-textured sediment were different from that of its fine-grained U(VI)-associated mass fraction. However, the desorption kinetics measured on the U(VI)-containing mass fraction could be scaled to describe U(VI) reactive transport in the contaminated field-textured sediment after proper consideration of the physical transport properties of the sediment. The research also demonstrated a modeling approach to integrate geochemical processes into field-scale reactive transport models.

Cyanobacterial Harmful Algal Blooms: Chapter 9: Causes, Prevention, And Mitigation Workgroup Report, Paul Berger, Justin Brooks, Terence Evens, Christopher Gobler, Jennifer Graham, James Hyde, Dawn Karner, Dennis (Kevin) O'Shea, Valerie Paul, Hans Paerl, Michael Piehler, Barry Rosen, Mary Santelmann, Pat Tester, Judy Westrick

United States Environmental Protection Agency: Publications

Cyanobacteria (blue-green algae) are estimated to have evolved 3.5 billion years ago, at which time they began to add oxygen to the existing anaerobic atmosphere, actually changing the chemistry of the planet and allowing new life forms to evolve. These ubiquitous microbes are capable of tolerating desiccation, hypersalinity, hyperthermal conditions, and high ultraviolet radiation, often for extensive periods of time. Recently, cyanobacteria have responded to human alterations of aquatic environments, most notably nutrient-enhanced primary production, or eutrophication. In fact, cyanobacterial blooms are now viewed as widespread indicators of freshwater, brackish and marine eutrophication.

Due to the complex interactions between physical …

The topic of exposure assessment overlaps with other topic areas of this workshop. It includes considerations of establishment of long term monitoring and event response, sampling protocols, development and standardization of organism and toxin assays, funding mechanisms, and public outreach. The development of a coordinated infrastructure (funding, human resources, and facilities, materials and equipment) is key to successfully addressing the threat posed by CHABs.
The establishment of validated standardized protocols to detect cyanobacteria and cyanotoxins is of considerable importance given the increased occurrence of CHABs worldwide. Standardized methods are needed for studies assessing occurrence, monitoring and toxicity studies which are …

The United States is faced with having to address critical issues that have not been addressed in the past, as recent security interests have placed new and more pressing demands on the assessment of risk from exposure to potential threats resulting from deliberate contamination. Such assessments are the basis for decisions about future research priorities, actions taken to prevent intentional contaminant releases, and developing detailed plans for response if such an event was to occur. High fidelity assessments are based on robust knowledge of the numerous parameters that can be used to predict the fate, transport, persistence, and toxicity for …

Nitrogen In The Environment: Chapter 10. Nitrogen Effects On Coastal Marine Ecosystems, J.R. Kelly

United States Environmental Protection Agency: Publications

Throughout the 20th century, a rapidly growing human population increased the global circulation of nitrogen (N). In the United States and elsewhere, human populations and activities have been disproportionately distributed towards coastlines, leading to markedly increased N inputs to coastal receiving waters. Nitrogen inputs to coastal waters come from the land, from the sea, and from the air; because of these multiple sources and the complexity of the N cycle, confident estimates of total N loading to coastal systems are not routine. Ecological problems from increasing inputs of N to coastal waters are well known and arise from stimulation of …

Enhanced Polymer Grafting From Multiwalled Carbon Nanotubes Through Living Anionic Surface-Initiated Polymerization, Georgios Sakellariou, Haining Ji, Jimmy W. Mays, Durairaj Baskaran

United States Department of Energy: Publications

Anionic surface-initiated polymerization of ethylene oxide and styrene has been performed using multiwalled carbon nanotubes (MWNTs) functionalized with anionic initiators. The surface of MWNTs was modified via covalent attachment of precursor anions such as 4-hydroxyethyl benzocyclobutene (BCBEO) and 1-benzocyclobutene-1′-phenylethylene (BCB-PE) through Diels-Alder cycloaddition at 235 °C. Surface-functionalized MWNTs-_g-(BCB-EO) _n and MWNTs-_g-(BCB-PE) _{n with 23 and 54 wt % precursor initiators, respectively, were used for the polymerizations. Alkoxide anion on the surface of MWNTs-g-(BCB-EO) n was generated through reaction with potassium triphenylmethane for the polymerization of ethylene oxide in tetrahydrofuran and phenyl substituted alkyllithium was …}

Generic Simulation Models For Facilitating Stakeholder Involvement In Water Resources Planning And Management: A Comparison, Evaluation, And Identification Of Future Needs, H. Assata, E. Van Beek, C.

United States Department of Energy: Publications

Water resources planning and management tools have been moving away from a top down (command and control) approach to a bottom up (grass-roots) approach - which emphasizes the involvement of stakeholders, not only specialists, in all stages of planning - from the identification of problems and issues, the selection of potential solutions to project implementation and operation. Ideally, a participatory grassroots planning process should provide a transparent and flexible platform for all stakeholders to collectively: examine the main elements of their shared water system; understand the main issues and problems to be addressed; participate in identifying alternative policies; and select …

Advective Removal Of Intraparticle Uranium From Contaminated Vadose Zone Sediments, Hanford, U.S., Eugene Ilton, Nikolla P. Qafoku, Chongxuan Liu, Dean Moore, John M. Zachara

United States Department of Energy: Publications

A column study on U(VI)-contaminated vadose zone sediments from the Hanford Site, WA, was performed to investigate U(VI) release kinetics with water advection and variable geochemical conditions. The sediments were collected from an area adjacent to and below tank BX-102 that was contaminated as a result of a radioactive tank waste overfill event. The primary reservoir for U(VI) in the sediments are micro-meter size precipitates composed of nanocrystallite aggregates of a Na- U-Silicate phase, most likely Na-boltwoodite, that nucleated and grew within microfractures of the plagioclase component of sand-sized granitic clasts. Two sediment samples, with different U(VI) concentrations and intra-particle …
