Jerry Poling Oral History Interview
No full textJerry Poling is the author of the book, A Summer Up North, and has been involved with much research and work on baseball in Eau Claire, Wisconsin. Mr. Poling discusses what prompted him to write his book, the love of baseball in Eau Claire, Wisconsin and the surrounding area, and his desire to learn more about Hank Aaron's time in Eau Claire. A comparison between baseball in Eau Claire and baseball nationwide was made involving the progress of baseball in Eau Claire from the 1860s to the 1950s and to the present Northern League team. Mr. Poling, a news-wire editor and a columnist for the Eau Claire Leader Telegram, commented on media coverage of baseball and how the media shaped baseball or vice-versa and how the baseball-media relationship compares to media in other sports. Mr. Poling discussed how he assembled his book, what he learned after the book was published that could have been included, such as his attempt to determine if Ann Landers attended any of Hank Aaron's games. Mr. Poling discusses the Eau Claire Express and other teams of that level. Mr. Poling mentions how his sources felt about how African-American players were viewed and treated in Eau Claire, how the newspaper covered high school baseball but not other youth baseball, and how media accommodations for Carson Park are limited and have changed a little over time. Mr. Poling's most memorable baseball game was during the Brewers' 1982 American League Championship Series. Mr. Poling reminisces about his first trip to a major league ballpark and comments on the present day Brewers team
Tunable acoustic attenuation in dilute suspensions of non-spherical magnetic particles
No full textThe microstructure of suspensions of ferromagnetic particles with subwavelength size can be controlled by an external field, making it possible to develop novel broadband acoustic materials with anisotropic and tunable acoustic properties. In this study we experimentally show that dilute suspensions of nickel micro-flakes exhibit a greater than 20% change in attenuation coefficient at MHz frequencies upon changing the direction of an external magnetic field, at particle volume fractions of only 0.5%. Optical transmission measurements and analysis of the characteristic timescales of particle alignment and chaining are used to study the mechanisms behind this acoustic anisotropy. By making comparison to suspensions of spherical particles, we show that the shape and orientation of the nickel micro-flakes play important roles in the tunable acoustic attenuation of these suspensions.Peer reviewed
Surface-charge effects on the electro-orientation of insulating boron-nitride nanotubes in aqueous suspension
No full textThe alignment of hexagonal boron-nitride nanotubes (BNNTs) in aqueous KCl solutions under spatially uniform electric fields was examined experimentally, using direct optical visualization to probe the orientation dynamics of individual BNNTs for different electric-field frequencies. Different from most previously studied nanowires and nanotubes, BNNTs are wide-bandgap materials which are essentially insulating at room temperature. We analyze the electro-orientation of BNNTs in the general context of polarizable cylindrical particles in liquid suspensions, whose behavior can fall into different regimes, including alignment due to Maxwell-Wagner induced dipoles at high frequencies, and alignment due to fluid motion of the electrical double layer around the particles at lower frequencies. For BNNTs, the variation of the crossover frequencies in the electro-orientation spectra was studied in electrolytes of different conductivity. The effect of BNNT surface charge on electro-orientation was further studied by changing the pH of the aqueous solution. We find that the electric-field alignment of the BNNTs in the low-frequency regime is associated with the charging and motion of the electrical double layer around the particle. However, as BNNTs are non-conducting particles, the reasons for the formation of the electrical double layer are likely to be different than that of conducting particles. We discuss two possible mechanisms for the double-layer formation and alignment of 1D dielectric particles, and make comparison to those for the more commonly studied conducting particles.Peer reviewe
Electrokinetics of Scalable, Electric-Field-Assisted Fabrication of Vertically Aligned Carbon-Nanotube/Polymer Composites
No full textComposite thin films incorporating vertically aligned carbon nanotubes (VACNTs) offer promise for a variety applications where the vertical alignment of the CNTs is critical to meet performance requirements, e.g., highly permeable membranes, thermal interfaces, dry adhesives, and films with anisotropic electrical conductivity. However, current VACNT fabrication techniques are complex and difficult to scale up. Here, we describe a solution-based, electric-field-assisted approach as a cost-effective and scalable method to produce large-area VACNT composites. Multiwall-carbon nanotubes are dispersed in a polymeric matrix, aligned with an alternating-current (AC) electric field, and electrophoretically concentrated to one side of the thin film with a direct-current (DC) component to the electric field. This approach enables the fabrication of highly concentrated, individually aligned nanotube composites from suspensions of very dilute (Φ = 4 X 10-4 volume fraction. We experimentally investigate the basic electrokinetics of nanotube alignment under AC electric fields, and show that simple models can adequately predict the rate and degree of nanotube alignment using classical expressions for the induced dipole moment, hydrodynamic drag, and the effects of Brownian motion. The composite AC + DC field also introduces complex fluid motion associated with AC electro-osmosis and the electrochemistry of the fluid/electrode interface. We experimentally probe the electric-field parameters behind these electrokinetic phenomena, and demonstrate, with suitable choices of processing parameters, the ability to scalably produce large-area composites containing VACNTs at number densities up to 1010 nanotubes/cm2. This VACNT number density exceeds that of previous electric-field-fabricated composites by an order of magnitude, and the surface-area coverage of the 40 nm VACNTs is comparable to that of chemical-vapor-deposition-grown arrays of smaller-diameter nanotubes.Peer reviewe
