3:00 PM - POLYMERS DIVISION SEMINAR: Field-Theoretic Simulations of Block Copolymer Melts for Nano Technology
Recent research suggests that ordered block copolymer (BCP) thin films can function as sub-micrometer lithographic masks in the fabrication of next - generation magnetic media and semiconductor devices. However, in order for the resulting patterned media to function correctly, these applications require near perfect uniformity and order of the BCP micro-domains. Numerous techniques have been developed to increase uniformity and order in BCP systems, including confinement, template-directed assembly, and the application of external fields. In this presentation, I will briefly review the equilibrium thermodynamics of BCPs melts and their potential applications in next - generation nano - fabrication, and then I will present a series of computational studies focused on confined BCPs melts and BCPs melts subjected to time-dependent thermal fields.

10:30 AM - MATERIALS AND CONSTRUCTION RESEARCH DIVISION SEMINAR SERIES: Boiling with Refrigerants and Nanolubricants
Is it possible to improve refrigerant/lubricant boiling with nanoparticles? If so, what size of particles should be used? What's the particle material and in what concentration should they be applied to obtain the best improvement in performance? These are some of the questions that are currently driving the refrigerant boiling with nanolubricant research at NIST. The presentation will share what has been learned, including very recent results at NIST in this ongoing investigation. Is it possible to improve refrigerant/lubricant boiling with nanoparticles?

10:45 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: Characterizing and Modeling the Shape of Particles in Three Dimensions
It has been estimated that 70 % of industrial processes involve some kind of particles, and of course, particles are ubiquitous in nature. Their size scale, for both man-made and naturally-occurring particles, range from a few nanometers up to many meters. This talk focuses on using a combination of X-ray computed microtomography (CT) and spherical harmonic analysis to characterize and model the shape of particles, in three dimensions, ranging in size from tens of millimeters down to tens of micrometers. There will also be some mention of focused ion beam techniques that can investigate sub-micrometer particles. The particles I have been mainly interested in have been those found in the cement and concrete industry (e.g., cement, sand, gravel), although I have studied other kinds of particles as well, including glass beads and calcium carbonate powders, and studies have been initiated on simulated lunar soil particles. Once the particles have been mathematically characterized, almost any kind of volume or surface integral can be performed for each particle, allowing for many shape parameters to be calculated. One result of the availability of having many shape parameters is that the "size" of particles turns out to be intimately related to their shape. An outstanding statistical problem is to generate new particles that are statistically "like" those of a class of particles that have been previously characterized. Progress on this problem will also be discussed.

1:00 PM - POLYMERS DIVISION SEMINAR: Shear thickening in an attractive colloidal system - scaling of the gel elasticity and dynamics of shear induced structures
Dilute dispersions of fractal particles in hydrocarbon solvents flocculate and form gels with typical scaling of elasticity with particle volume fraction. Surprisingly, these attractive systems display shear thickening in two distinct regimes. At low shear rates, shear thickening is concurrent with the formation of stable vorticity-aligned structures. At high shear rates, shear thickening involves the breakdown of dense particle clusters into smaller aggregates. Pre-shear within the high shear rate shear thickening regime leads to enhanced modulus gels where storage modulus scales as a power law with the pre-shear stress. We propose a simple scaling model that accounts for this in terms of stress controlled cluster number density. Shear-rate quenches from shear thickening flows into the quiescent state result in rapid gelation accompanied by slowly decaying internal stresses. Deformation of these mechanically quenched gels is highlighted by the transient formation of highly anisotropic vorticity aligned structures and the relaxation of residual internal stresses.

5/9 -- FRIDAY

10:30 AM - POLYMERS DIVISION SEMINAR: Measurement Needs Related to Interfacial Phenomena in Aircraft Manufacture
Measurement needs arise from a variety of airplane manufacturing challenges, economic considerations, and regulatory drivers. Among the challenges are the large physical scale of the airplane which necessitates spray application of materials, the range of application and in-service environmental conditions which must be tested, and the accelerating shift from aluminum to composite substrates. Drivers for development and the need for suitable tests include improved durability of materials and more environmentally-friendly materials and methods. This talk gives examples where improved test methods and application of combinatorial methodology will be beneficial. Interlayer adhesion issues in exterior decorative paint are used to illustrate the need for better simulation of rain erosion as well as showing the complexity of application, environmental, and compositional variables which must be considered. Contamination in exterior painting and adhesive bonding is discussed to show opportunities for improvements in measurement protocols as well as to demonstrate the difficulties added by composite substrates. Sol-gel coatings used as pre-treatments for bonding adhesives are discussed to illustrate the range of variables that must be investigated and the development of tests needed to look at the interfacial behavior of thin adherent films. Lastly, sealant application on composite is used to illustrate the combinatorial complexity associated with material qualification and the desire for better tests relating engineering properties to material property structure

5/16/08 1:30 PM - CENTER FOR NANOSCALE SCIENCE AND TECHNOLOGY SEMINAR: Spin Wave Beams, Precessing Vortices, and Localized Standing Waves in Single Layer Nanocontacts
The recently discovered spin transfer effect enables the application of localized torques in magnetic thin film nanostructures. In the point contact geometry, this effect can result in large amplitude spin wave generation. The well studied Slonczewski model of spin torque in trilayer nanostructures is the Landau-Lifshitz equation modified with a local spin torque term. In this talk, a non-local model of point contacts in single layer thin magnetic films is presented and studied numerically in two spatial dimensions. Here, the spin torque term in the Landau-Lifshitz equation is non-local and is due to spin diffusion effects. A variety of quasi-periodic mode solutions to this equation are found including localized standing waves, vortex spiral waves, and a weakly diffracting collimated beam of spin waves, the direction of which can be steered by changing the direction of an applied magnetic field. The spin wave beam appears to be the nonlinear hybridization of the vortex spiral waves and the localized standing wave. Mode selection is explained using linear spin wave theory.
