Rapid Microwave Synthesis of the Iron Arsenides NdFeAsO and NdFe₀.₉Co₀.₁AsO

Creator:: Muir, Sean, Rachdi, Omar, and Subramanian, Mas
Abstract:: The future of iron pnictide superconductors in technology is still undecided. While these materials are now known to possess high critical temperatures and critical magnetic fields processing methods for these materials are still in their infancy. Recently we have been investigating possible ways to speed up the synthetic process for...

Refractive Index and Optical Dispersion of In2O3, InBO3 and Gahnite

Creator:: Medenbach, O., Siritanon, Theeranun, Subramanian, Mas, Dettmar, D., Shannon, R. D., and Fischer, R. X.
Abstract:: Refractive indices of In₂O₃, In₂₋ₓSnₓO₃, InBO₃ and 2 different gahnite crystals (ZnAl₂O₄ and Zn.₉₅Fe.₀₅Al₂O₄) were measured at wavelengths of 435.8 to 643.8 nm and were used to calculate n at λ = 589.3 nm ( nD ) and at λ = ∞ (n∞) using the one-term Sellmeier equation 1/(n²-1) =...

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...

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...

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...

Biotic and abiotic factors impacting development, behavior, phenology, and reproductive biology of Drosophila suzukii

Creator:: Hamby, Kelly A., Bellamy, David E., Chiu, Joanna C., Lee, Jana C., Walton, Vaughn M., Wiman, Nik G., York, Riki M., and Biondi, Antonio
Abstract:: Spotted wing drosophila, Drosophila suzukii, is a devastating invasive pest of small and stone fruits in the Americas and Europe. To better understand the population dynamics of D. suzukii, we reviewed recent work on juvenile development, adult reproduction, and seasonal variation in life history parameters including the abiotic/biotic factors that...

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...

Permanence for wood siding

Creator:: Verrall, A. F. (Arthur Frederic), 1905-2002 and United States. Division of Forest Pathology
Abstract:: Until the last decade, decay in siding did not present a problem. When it occurred it was usually limited to a few boards where there had been some obvious error; for example at points where large amounts of rain water were allowed to run down the wall from leaks in...

Individual tree selection (ITS) in a northeast Oregon mixed conifer forest

Creator:: Fitzgerald, Stephen Arthur, Oester, Paul T., Parker, Robert, 1941-, and Oregon State University. Extension Service
Abstract:: Forest landowners are interested in practicing alternative silviculture methods on their property without having to clearcut. This publication describes a case study on Individual Tree Selection (ITS) in a mixed conifer forest in Northeast Oregon. ITS is of interest because it provides a continuous forest canopy; potentially reduces reforestation costs;...
