Program Highlights for year 2012

Dynamic Electrostatic Lithography: Multiscale On-demand Patterning on Large Area Curved Surfaces

Triangle MRSEC researchers have invented a new technology for the use of electrical voltages to dynamically generate various patterns on curved surfaces and over large areas, such as the surfaces of gloves.

Professional Development Workshop for Teachers

MRSEC postdoc, Dr. Kermin Martínez-Hernández; Visiting Scholar, Sandy Sine; and former MRSEC RET participant, Troy Dassler organized a workshop “Integrating cutting-edge nanotechnology into the inquiry-based learning experience.” This was part of the professional development workshop prepared for Middle Year’s Science

Liquid Crystal Nanodroplets, and the Balance Between Bulk and Interfacial Interactions

Molecular dynamics simulations of a coarse grain model are used to explore the morphology of thermotropic liquid crystal nanodroplets. The characteristic length of the droplets is such that different contributions to the energy, including interfacial and bulk-like terms, have comparable magnitudes.

Enantiomeric Interactions between Liquid Crystals and Organized Monolayers of Tyrosine-Containing Dipeptides

IRG 3 has examined the orientational ordering of nematic liquid crystals (LCs) supported on organized monolayers of dipeptides with the goal of understanding how peptide-based interfaces encode intermolecular interactions that are amplified into supramolecular ordering.

Adding a Dimension to the Infrared Spectra of Interfaces using Heterodyne Detected 2D Sum-Frequency Generation (HD 2D SFG) Spectroscopy

In the last ten years, two-dimensional infrared spectroscopy has become an important technique for studying molecular structures and dynamics. We report the implementation of heterodyne detected two-dimensional sum-frequency generation (HD 2D SFG)

New Dual Beam Focused Ion Beam System

Objective: To develop nanofabrication capabilities that will allow for writing structures as small as ~10 nm.

Approach: Use MRSEC funds provided by the State of Utah to purchase state-of-the-art nanofabrication capabilities to expand existing materials research capabilities.

Silicon Integrated High Speed Electrooptic Modulators

On-chip optical modulation is one of the most important functionalities for integrated silicon photonic circuits. We demonstrate that sputter-deposited polycrystalline metallic thin films are promising materials for realizing ultra-low power modulators.

CRISP NanoDays and Yale Pathways

On March 22, 2012, CRISP, in collaboration with Yale's Science Pathways, hosted a public lecture in support of the 2012 NanoDays national outreach campaign. IRG2 leader Jan Schroers gave a talk entitled, Strong as Steel, but Pliable as Plastic: Metals Conquering the Nanoworld. Hands-on demonstrations for students were provided by CRISP researchers.
