Underlayer Effect on Perpendicular Magnetic Anisotropy in Co(sub20)Fe(sub60)B(sub20)/MgO

July 1, 2016

Author(s)

Andrew P. Chen, Yury Y. Iunin, S F. Cheng, Robert D. Shull

Perpendicular Magnetic Tunneling Junctions (pMTJs) with Ta\CoFeB\MgO have been extensively studied in recent years. However, the effects of the underlayer on the formation of the CoFeB perpendicular magnetic anisotropy (PMA) are still not well understood

Attractive Interactions between DNA-Carbon Nanotube hybrids in Monovalent Salts

June 30, 2016

Author(s)

Ming Zheng, Xiangyun Qiu, Fuyou Ke, Raju Timsina, Constantine Y. Khripin

DNA-carbon nanotube (DNA-CNT) hybrids are nanometer-sized, highly-charged, rod-like molecules with complex surface chemistry, and their behaviors in aqueous solutions are governed by multifactorial interactions with both solvent and co-solutes. We have

Costs, Benefits, and Adoption of Additive Manufacturing: A Supply Chain Perspective

June 30, 2016

Author(s)

Douglas Thomas

Currently, additive manufactured products represent less than one percent of all manufactured products in the US; however, as the costs of additive manufacturing systems decrease, this technology may become widely adopted and change the supplier

Crystal Plasticity Analysis of Constitutive Behavior of 5754 Aluminum Sheet

June 30, 2016

Author(s)

Minh-Son Pham, Anthony D. Rollett, Adam Abel Creuziger, Mark Iadicola, Timothy J. Foecke

Crystal plasticity constitutive equations for the multi-axial stress-strain behavior of aluminum alloy 5754 sheets have been developed. A Taylor model, a self-consistent visco-plastic model and an N-site model based on the Fast Fourier Transform were used

Determination of Residual Stress Distributions in Polycrystalline Alumina using Fluorescence Microscopy

June 30, 2016

Author(s)

Chris A. Michaels, Robert F. Cook

Maps of residual stress distributions arising from anisotropic thermal expansion effects in a polycrystalline alumina are generated using fluorescence microscopy. The shifts of both the R1 and R2 ruby fluorescence lines of Cr in alumina are used to create

Fast Dynamic Programming for Elastic Registration of Curves

June 30, 2016

Author(s)

Javier Bernal, Gunay Dogan, Robert Hagwood

Curve registration problems in data analysis and com- puter vision can often be reduced to the problem of match- ing two functions defined on an interval. Dynamic Pro- gramming (DP) is an effective approach to solve this prob- lem. In this paper, we

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016

Author(s)

Felipe F. Lopez, Paul Witherell, Brandon Lane

A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced

Inspection of embedded internal features in additively manufactured metal parts using metrological x-ray computed tomography

June 30, 2016

Author(s)

Felix H. Kim, Herminso Villarraga-Gomez, Shawn P. Moylan

Advances in metal additive manufacturing (AM) have made it possible to build parts with complex geometry. Metal AM has a high potential to impact various industries including aerospace and automotive. Complex interior features can be designed to reduce

Measured Wavelength-Dependent Absorption Enhancement of Internally Mixed Black Carbon with Absorbing and Nonabsorbing Materials

June 30, 2016

Author(s)

Rian You, James Radney, Michael R. Zachariah, Christopher D. Zangmeister

Optical absorption spectra of laboratory generated aerosols consisting of black carbon (BC) internally mixed with nonabsorbing materials (ammonium sulfate, AS, and sodium chloride, NaCl) and BC with a weakly absorbing brown carbon surrogate derived from

Measuring multiple, weak heteronuclear 13C-2H couplings involving large 2H quadrupolar coupling constants and large 13C chemical shift anisotropy values: An experimental and theoretical REDOR study

June 30, 2016

Author(s)

Ryan C. Nieuwendaal

We discuss the implementation of a REDOR experiment that is capable of measuring multiple, weak 13C-2H dipolar couplings when 2H is a strong quadrupole and 13C exhibits large chemical shift anisotropy. We find that at 7.05 T in the presence of large 13C
