Evaluation of various chemical treatments to prevent the abiotic deterioration of southern pine surfaces through outdoor screening trials

Creator:: Schauwecker, Christoph F.
Abstract:: Rapid discoloration and checking of wooden surfaces when exposed outdoors has caused wood to fall out of favor as an outdoor building material, especially in applications where appearance is important. The surface appearance of wood products exposed outdoors can be improved through the application of film forming coatings or by...

Management of powder-post beetles, Dinoderus minutus F. in freshly cut bamboo

Creator:: Garcia, Carlos Manalo
Abstract:: The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and ftmgi associated with beetles were investigated. Finally, the...

Electron diffraction of molecules in superfluid helium droplets

Creator:: He, Yunteng
Abstract:: In this dissertation, I describe the experimental investigation in electron diffraction of molecules in superfluid helium droplets. The project is part of an overall scheme called ‘single molecule serial electron diffraction imaging’ (SS-EDI), with the ultimate goal of building an apparatus to determine atomic structures from oriented macromolecules. In SS-EDI,...

Bioactive glass filled resin composites : mechanical properties and resistance to secondary tooth decay

Creator:: Khvostenko, Dmytro
Abstract:: Dental resin composites are widely used in modern dentistry due to their aesthetic appearance. However, resin based restorations have inferior mechanical properties (fracture is the second reason for restorations replacement) in comparison to alloy based composites and their antimicrobial properties still remain poor, leading to secondary tooth decay development on...

Formaldehyde-free wood adhesives from soybean protein and lignin : development and characterization

Creator:: Liu, Yuan
Abstract:: Presently, the production of wood composites relies on the formaldehyde-based wood adhesives such as phenol-formaldehyde (PF) and urea-formaldehyde (UF). However, their dependence on exhaustible fossil fuels and the emission of carcinogenic formaldehyde prompt to develop an environmentally friendly adhesive from renewable natural resources. This work focuses on development and characterization...

Insights and Patterns from Quantitative and Statistical Analyses of Chemical Systems

Creator:: Grove, Markas Albert
Abstract:: The work presented here is the culmination of efforts in describing complex chemical systems with statistical methods, thereby providing relatively simple quantitative models and easily comprehensible qualitative insights. The following investigations have various goals, such as development of new methods, fundamental understanding, molecular control of chemical species, and advancement of...

Structure-property Relationships of Transition Metal Oxides Containing Precious Metals

Creator:: Hapuraja Pathirannehelage, Vidhara H. P.
Abstract:: This dissertation presents a study of structure-property relationships within 3d/4d metal oxides containing precious metals through detailed structure refinements using high-resolution neutron and X-ray diffraction data along with exploration of the resultant properties. Oxides of 4d or 5d transition metals tend to show new topological phases due to significant spin-orbit...

In-situ Surface Modification of Wood with Different Hot Press Platen Metallurgies

Creator:: Freitas, Shawn Robert
Abstract:: As the forest industry moves toward the use of younger trees and production of an increasing number of composite products improving durability has gained importance. Coatings are one of the most widely used methods for improving wood durability because they improve resistance to water penetration, and subsequent shrinking and swelling,...

Functional Materials and Techniques for Additive Manufacturing in Soft Robotics

Creator:: Walker, Stephanie
Abstract:: This thesis outlines the development of new elastomeric materials and manufacturing processes for soft robotics. Specifically, this work describes the development of custom material formulations for use in additive manufacturing, additive manufacturing processing techniques for silicone elastomers, and multi-component additive manufacturing techniques. Material synthesis and processing is a gap in...
