Report from Open Problems Session at OPSFA-13

July 21, 2016
Author(s)
Howard S. Cohl, Richard Askey, Rick Beatson, Charles Dunkl, Christoph Koutschan, Sheehan Olver, Yuan Xu, Wolfgang Zu Castell, Wadim Zudilin, Ted Chihara
We provide the open problems presented at OPSFA-13, Gaithersburg, Maryland, June 4, 2015. Howard Cohl, National Institute of Standards and Technology, has collected these open problems.

Ultraviolet/Ozone as a tool to control grafting density in surface-initiated controlled-radical polymerizations via ablation of bromine

July 21, 2016
Author(s)
Richard J. Sheridan, Sara V. Orski, Shinichiro Muramoto, Christopher M. Stafford, Kathryn L. Beers
We used an ultraviolet-ozone (UVO) cleaner to create substrates for atom-transfer radical polymerization (ATRP) with varying surface initiator coverage. We collected complementary time-of-flight secondary ion mass spectrometry (ToF-SIMS) and X-ray

Additive Manufacturing: A Trans-disciplinary Experience

July 20, 2016
Author(s)
Paul W. Witherell, Albert W. Jones, Yan Lu
Traditional manufacturing has long permitted disciplines to operate in isolation: with designers, material suppliers, and manufactures often able to function independently towards the singular goal of creating a product. As products have become

Measurement-induced decoherence and information in double-slit interference

July 20, 2016
Author(s)
Joshua Kincaid, Kyle McLelland, Michael P. Zwolak
The double slit experiment provides the classic example of both interference and the effect of observation in quantum physics. When particles are sent individually through a pair of slits, a wave-like interference pattern develops; no such interference is

Using Category Theory to facilitate multiple manufacturing service database integration

July 20, 2016
Author(s)
Spencer J. Breiner, Albert T. Jones, David I. Spivak, Eswaran Subrahmanian, Ryan Wisnesky
The goal of this paper is to illustrate the use of category theory as a basis for the integration of manufacturing service databases. In this paper we use as our reference prior work by Kolvatunyu, et. al (2013) on the use of Ontology Web Language(OWL)

Anti-corrosive influence of Acetobacter biofilms on carbon steel

July 19, 2016
Author(s)
Danielle C. France
Microbiologically influenced corrosion (MIC) of carbon steel infrastructure is an emerging cost issue for the ethanol fuel industry. One bacterial species found in ethanol fuel environments, Acetobacter aceti, can convert ethanol to the corrosive species

FREE-STANDING SELF-ASSEMBLIES OF GALLIUM NITRIDE NANOPARTICLES: A REVIEW

July 19, 2016
Author(s)
Winnie K. Wong-Ng, Yucheng Lan, Jianye Li, Rola M. Derbeshi, Abdellah Lisfi
Gallium nitride (GaN) is an III-V semiconductor with a direct band-gap of 3.4 eV. GaN has important potentials in white light-emitting diodes, blue lasers, and field effect transistors because of its super thermal stability and excellent optical properties

Spatially patterned matrix elasticity directs stem cell fate

July 19, 2016
Author(s)
Chun Yang, Frank W. DelRio, Lena Basta, Hao Ma, Kyle Kyburz, Anouk Killaars, Kristi Anseth
There is a growing appreciation for the functional role of matrix mechanics in regulating stem cell self-renewal and differentiation. However, it is largely unknown how sub-cellular, spatial mechanical variations in the local extracellular environment

Coherent and incoherent coupling dynamics between neutral and charged excitons in Monolayer MoSe2

July 18, 2016
Author(s)
Kai Hao, Lixiang Xu, Philip Nagler, Akshay Singh, Kha Tran, Chandriker K. Dass, Rupert Huber, Tobias Korn, Xiaoqin Li, Galan Moody
The optical properties of semiconducting transition metal dichalcogenides are dominated by both neutral excitons (electron-hole pairs) and charged excitons (trions) that are stable even at room temperature. While trions directly influence charge transport
