Formation of zinc oxide films using submicron zinc particle dispersions

Creator:: Rajachidambaram, Meena S., Varga, Tamas, Kovarik, Libor, Sanghavi, Rahul, Shutthanandan, Vaithiyalingam, Thevuthasan, Suntharampillai, Han, Seung-Yeol, Chang, Chih-Hung, and Herman, Gregory S.
Abstract:: The thermal oxidation of submicron metallic Zn particles was studied as a method to form nanostructured ZnO films. The particles used for this work were characterized by electron microscopy, x ray diffraction, and thermal analysis to evaluate the Zn-ZnO core shell structure, surface morphology, and oxidation characteristics. Significant nanostructural changes...

Size effects on the nanomechanical properties of cellulose I nanocrystals

Creator:: Pakzad, Anahita, Simonsen, John, Heiden, Patricia A., and Yassar, Reza S.
Abstract:: The ultimate properties of a fibrous composite system depend highly on the transverse mechanical properties of the fibers. Here, we report the size dependency of transverse elastic modulus in cellulose nanocrystals (CNCs). In addition, the mechanical properties of CNCs prepared from wood and cotton resources were investigated. Nanoindentation in an...

A Highly Fatigue-Resistant Zr-Based Bulk Metallic Glass

Creator:: Naleway, Steven E., Greene, Rawley B., Gludovatz, Bernd, Dave, Neil K. N., Ritchie, Robert O., and Kruzic, Jamie J.
Abstract:: The strength-normalized fatigue endurance strength of the bulk metallic glass (BMG) Zr₅₂.₅Cu₁₇.₉Ni₁₄.₆Al₁₀Ti₅ (Vitreloy 105) has been reported to be the highest for any BMG; however, to date, there has been no explanation of why this material is so much better than other Zr-based compositions. In this study, the fatigue-crack growth...

Mechanistic aspects of fracture and fatigue in resin based dental restorative composites

Creator:: Shah, Minalben B.
Abstract:: For resin based dental restorative composites, one of the major challenges is to optimize the balance between mechanical and optical properties. Although fracture is the second leading cause of dental restorative failures, very limited mechanistic understanding exists on a microscopic level. In the present study, the fracture properties and mechanisms...

Innovative Data Acquisition for the Fall Cone Test in Teaching and Research

Creator:: Evans, T. M. and Simpson, D. C.
Abstract:: The fall cone device may be preferable to the Casagrande cup for the determination of liquid limits because it is based on a firm theoretical background and maintains a high degree of operator independence. This makes the fall cone device a superior tool for measuring consistency limits for research and...

The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

Creator:: Bozeman, Scott C.
Abstract:: Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

Processing of nanoscale materials

Creator:: Hostetler, Eric B.
Abstract:: The motivation for undertaking this research was to increase the understanding of processing colloidal semiconductor nanocrystals and thin films metallic glasses to enable their wider application in future devices. This research covered two unique materials, lead selenide (PbSe) nanocrystals and thin film metallic glass alloy of zirconium copper aluminum nickel...

Chemical Solution Deposition and in-situ Structural Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

Creator:: Fox, Austin J.
Abstract:: This work explores the electric field induced strain mechanisms in environmentally benign Bi0.5Na0.5TiO3 (BNT) based piezoelectric thin films. Although BNT-based materials show promise as replacements for toxic Pb-based piezoelectrics, the displacement mechanisms are not consistent between thin films and bulk materials, and the differences have yet to be well understood....

The creep and microstructure of copper

Creator:: Long, Michael D.
Abstract:: Creep experiments were conducted on copper polycrystals deformed within the five-power-law regime. The dislocation structure of copper, which has not been extensively characterized in the past, consists of less-well-defined subgrain walls of relatively low misorientation, typically between 0.1 and 0.3 deg, with a Frank network of dislocations within the subgrains....
