Heterogeneous Oxidation Of Catechol, Elizabeth A. Pillar, Ruixin Zhou, Marcelo I. Guzman

Chemistry Faculty Publications

Natural and anthropogenic emissions of aromatic hydrocarbons from biomass burning, agro-industrial settings, and fossil fuel combustion contribute precursors to secondary aerosol formation (SOA). How these compounds are processed under humid tropospheric conditions is the focus of current attention to understand their environmental fate. This work shows how catechol thin films, a model for oxygenated aromatic hydrocarbons present in biomass burning and combustion aerosols, undergo heterogeneous oxidation at the air–solid interface under variable relative humidity (RH = 0–90%). The maximum reactive uptake coefficient of O₃(g) by catechol γ_O3 = (7.49 ± 0.35) × 10^–6 occurs for …

Nanoscaled Cellulose And Its Carbonaceous Material: Application And Local Structure Investigation, Yujie Meng

Doctoral Dissertations

In this dissertation, cellulose nanocrystals three-dimensional morphology, size distribution, and the crystal structure were statistically and quantitatively investigated. Lognormal distribution was identified as the most likely for cellulose nanocrystals’ size distribution. Height and width dimensions were shown to decrease toward the ends from the midpoint of individual CNCs, implying a spindle-like shape. XRD analysis of crystallite size accompanied with TEM and AFM measurements revealed that the cross-sectional dimensions of individual switchgrass CNC were either rectangular or elliptical shape, with an approximately 3~5 nm [nanometer] lateral element length range. A sponge-like carbon aerogel from microfibril cellulose with high porosity, ultra-low density, …

Development Of Cross Laminated Timber In The United States Of America, Karl Konstantin Grasser

Masters Theses

This research focuses on the establishment of Cross Laminated Timber (CLT) ventures in the United States of America (USA) and provides interested stakeholders knowledge about the product and the existing CLT industry. This research is designed to improve knowledge of CLT and manufacturing technologies for potential investors of CLT capacities in the USA.

The invention of CLT in Austria led to a paradigm change in European wood construction as it allowed the woodworking industry to enter new construction markets such as multi-story residential and non-residential buildings. The CLT industry has experienced tremendous growth in Europe. The United States is a …

Improving Alternate Lignin Catabolite Utilization Of Ligab From Sphingobium Sp. Strain Syk-6 Through Site Directed Mutagenesis, Kevin P. Barry, Erin F. Cohn, Abraham Ngu, Erika A. Taylor

Erika A. Taylor, Ph.D.

Protocatechuate 4,5-dioxygenase (LigAB) catalyzes dioxygenation of multiple lignin derived aromatic compounds—such as protocatechuate (PCA), gallate (GA) and 3-O-methyl gallate (3OMG)—with decreasing proficiency as the molecule size increases. We predicted that phenylalanine-103 of the α subunit (Phe103α) controls substrate specificity through interaction with the C5-funtionality of bound substrates, and mutagenesis would enhance GA and 3OMG catalysis. LigAB with Phe103α mutations (F103 V, F103T and F103H) displayed enhanced catalytic efficiency for dioxygenation of 3OMG, with mutants displaying 12- to 31-fold increases in View the MathML source, making these mutant enzymes more active with 3OMG than its native dioxygenase (DesZ). The F103T and …

Annual Brome Biocontrol After Wildfire Using A Native Fungal Seed Pathogen, Susan E. Meyer, Phil S.

Benjamin L. Harwood

A major problem in post-fire restoration of semi-arid shrublands dominated by annual bromes is the presence of carryover seed banks that cannot be controlled using conventional methods. These seeds can provide significant competition for seeded species in the years following treatment. We investigated the feasibility of using a naturally occurring seed pathogen, the ascomycete Pyrenophora semeniperda, as a biocontrol organism for eliminating this carryover seed bank. We carried out the necessary technology development to create and apply field inoculum to cheatgrass- or red brome-infested areas (both burned and unburned) at six sites located in three states across two years of …

Fire, Fuels, And Streams: The Effects And Effectiveness Of Riparian Treatments, Josh Mcdaniel

Joint Fire Science Program Digests

Fire is an important disturbance in riparian systems—consuming vegetation; increasing light; creating snags and debris flows; altering habitat structure; and affecting stream conditions, erosion, and hydrology. For many years, land managers have worked to keep fire out of riparian systems through the use of buffers. A number of projects funded by the Joint Fire Science Program are shedding light on the dynamics of fire in riparian systems. Recent research and field practice have shown that (1) riparian treatments can be beneficial and are not as risky as previously thought; and (2) riparian treatments need the “Goldilocks” prescribed fire—not too hot …

Nebraska Statewide Forest Action Plan - 2015, Scott Josiah, John Erixson

Nebraska Forest Service: Publications

The Nebraska Forest Action Plan identifies strategic goals based on national objectives collaboratively crafted by both the National Association of State Foresters and the USFS State & Private Forestry Program. The strategic goals and actions identified in this document serve as a blueprint for focusing private, state and federal resources in areas of Nebraska where they will be most effective.

Evaluation Of A Generalized Basal Area Stand Table Projection Model For Appalachian Hardwoods Growth And Yield Systems, Aaron M. Holley

Graduate Theses, Dissertations, and Problem Reports

A generalized stand table projection algorithm was used to disaggregate species group level data for the Fernow Experimental Forest in the Allegheny Front physiographic region of the Central Appalachian Hardwoods region. The generalized stand table projection method has proved effective in projecting multi and uni-modal distributions in single species stands. Exploration into the potential for use in mixed species Central Appalachian Hardwoods thinned and unthinned stands proved promising. When compared to basal area projections using SILVAH, generalized stand table projection outperformed SILVAH at the plot level. Generalized stand table projection produced smaller errors on non-overlapping growth projections for both thinned …
