Design Of Cotton Fabric-Based Binary And Ternary Composite Materials Containing Nanostructured Zno, Tio2, And Plasmonic Nanoparticles: Photocatalytic Applications, Latanya Downer
Master of Science in Chemical Sciences Theses
Nanostructure metals and metal oxides can be used for surface functionalization and combined with different materials to increase functionality. Recently, surface functionality has been of interest due to its multi-component and its ability to generate new material properties. One of its main application is the creation of nanomaterials because of its novel physical properties which contribute towards stabilization, strength, and catalytic properties. Nanomaterials makes it possible to fabricate objects in the nanoscale size range which offers beneficial physical properties. The nanomaterial distinctiveness allows for the creation of materials with unique characteristics for different applications such as photocatalytic coatings. Semiconductor and …
Effects Of Strand Geometry On Selected Properties Of Long-Stand Structural Composite Lumber Made From Northeastern Hardwoods, Russell Edgar
Effects Of Strand Geometry On Selected Properties Of Long-Stand Structural Composite Lumber Made From Northeastern Hardwoods, Russell Edgar
Electronic Theses and Dissertations
Structural composite lumber (SCL) products often possess significantly higher design values than the top grades of solid lumber, making it a popular choice for both residential and commercial applications. The enhanced mechanical properties of SCL are mainly due to defect randomization and densification of the wood fiber, both largely functions of the size, shape and composition (species) of the wood element. Traditionally, SCL manufacturers have used thin, rectangular elements produced from either moderate density softwoods or low density hardwoods. Higher density hardwood species have been avoided, as they require higher pressures to adequately densify and consolidate the wood furnish. These …
Evaluating The Durability Of Wood/Frp Bonds Through Chemical Kinetics Using A Range Of Mechanical Test Methods, Jonathan Philip Alexander
Evaluating The Durability Of Wood/Frp Bonds Through Chemical Kinetics Using A Range Of Mechanical Test Methods, Jonathan Philip Alexander
Electronic Theses and Dissertations
Hybrid composites of wood and fiber reinforced polymers (FRP) exhibit a flexibility of design properties through choices in fiber type, amount, orientation and resin type. With this flexibility comes the need to measure the durability of the composite material system, especially the bond between these two materials due to their markedly different responses to moisture. This study is two-fold; the first section examines methods for the mechanical testing and durability of wood/FRP laminations. Six mechanical tests were evaluated and a modified block shear method was identified as the most suitable due to its ability to provide representative results independent of …
