Complex Oxides and the Philosopher’s Stone
26 May 2016 | | Contributor(s):: Shiram Ramanathan
In this talk I will discuss the topic of insulator-metal transitions in strongly correlated oxides, their control via disorder, orbital occupancy and electric fields and challenges these systems pose to our contemporary understanding of emergent phenomena in ionic lattices.
IMA 2013 UQ: Bayesian Calibration of Molecular Dynamics Simulations for Composite Materials Properties
28 May 2014 | | Contributor(s):: Paul N. Patrone
In this talk, I discuss ongoing research whose goal is to determine, via Bayesian inference, an ensemble of inputs that represents a class of commercially important amine-cured epoxies. We construct an analytical approximation (i.e. a surrogate or emulator) of the simulations, treating the input...
IMA 2013 UQ: Foam Property Prediction from Process Modeling
28 May 2014 |
We are developing computational models to elucidate the injection, expansion, and dynamic filling process for polyurethane foam such as PMDI. The polyurethane is a chemically blown foam, where carbon dioxide is produced via reaction of water, the blowing agent, and isocyanate. In a competing...

20 Nov 2012 | | Contributor(s):: Elif Ertekin
Title: Advances in first-principles computational materials scienceSubtitle: Things we can calculate now, that we couldn't when I was in grad school.The capability to rationally design new materials with tailored properties and functionality on a computer remains a grand challenge whose success...
Experiments and Models Regarding Strain Dependent Thermal Conductivity and Strength at the Nanoscale and Microscale
22 Sep 2011 | | Contributor(s):: Vikas Tomar
Silicon micro- and nano-structures are essential in today’s integrated circuits and sensors. The functioning and performance of such devices are highly affected by thermal properties. Due to the size effect, the thermal properties of bulk silicon cannot represent those of silicon...

Levitated Spinning Graphene
18 Jan 2011 | | Contributor(s):: Bruce E. Kane
I will describe a method for levitating micron-sized few layer graphene flakes in a quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes are injected into the trap using the electrospray ionization technique and are probed optically.

Self-Consistent Geometry, Density and Stiffness of Carbon Nanotubes
05 May 2010 | | Contributor(s):: R. Byron Pipes
A self-consistent set of relationships is developed for the physical properties of single walled carbon nanotubes (SWCN) and their hexagonal arrays as a function of the chiral vector integer pair, (n,m). Properties include effective radius, density, principal Young’s modulus, and specific Young’s...
