Gradient Chemical Micropatterns: A Reference Substrate for Surface Nanometrology

August 1, 2005
Author(s)
D Julthongpiput, Michael J. Fasolka, Wenhua Zhang, Tinh Nguyen, Eric J. Amis
We present fabrication routes for a new type of surface specimen that exhibits a micropattern with a gradient in chemical contrast between the pattern domains. Design elements in the specimen allow chemical contrast in the micropattern to be related to

Effects of Surface Functionality and Humidity on The Adhesion Force and Chemical Contrast Measured With AFM

January 1, 2005
Author(s)
Tinh Nguyen, Xiaohong Gu, lijiang chen, Michael J. Fasolka, Kimberly Briggman, Jeeseong C. Hwang, Jonathan W. Martin
The ability to probe chemical heterogeneity with nanometer scale resolution is essential for developing a molecular level understanding of a variety of phenomena occurring at surfaces of materials. One area that could benefit greatly from nanoscale

Monolayer Formation of PBLG-PEO Block Copolymers at the Air-Water Interface

November 11, 2004
Author(s)
Y Park, Y W. Choi, SK Park, C S. Cho, Michael J. Fasolka, Daeson Sohn
Physicochemical properties of PBLG (poly(gamma-benzyl-L-glutamate))-PEO (poly(ethylene oxide)) diblock copolymers composed of PBLG as the hydrophobic rod component and PEO as the hydrophilic component were investigated at the air-water interface. Surface

Near-Field Polarimetric Characterization of Polymer Crystallites

August 1, 2004
Author(s)
Lori S. Goldner, S N. Goldie, Michael J. Fasolka, F Renaldo, Jeeseong Hwang, Jack F. Douglas
We use near-field polarimetry (NFP) to investigate thin film crystallites of isotactic polystyrene (iPS). NFP micrographs enabled quantitative optical characterization of the birefringence in these specimens with sub-diffraction limited resolution

Gradient Reference Specimens for Advanced Scanned Probe Microscopy

July 1, 2004
Author(s)
D Julthongpiput, Michael J. Fasolka, Eric J. Amis
Recent years have seen the emergence of a new generation of SPM techniques, which intend to measure chemical, mechanical, and electro/optical properties on the nanoscale. Currently, these techniques provide qualitative (or semi-quantitative) data, often

An Open Source Informatics System for Combinatorial Materials Research

March 1, 2004
Author(s)
Weiping Zhang, Michael J. Fasolka, Alamgir Karim, Eric J. Amis
Laboratory Research Informatics Systems (LRIS) hold great promise in streamlining research generally, and are particularly necessary for new data-intensive research strategies such as combinatorial and high-throughput approaches. In this talk, we describe

High Throughput Measurement of the Elastic Modulus of Polymer Thin Films

February 1, 2004
Author(s)
Christopher M. Stafford, A Chiche, D Julthongpiput, Michael J. Fasolka
Combinatorial and High Throughput (C&HT) methods combine clever experiment design, instrument automation, and computing tools to form a new paradigm for scientific research. Given this premise, the C&HT concept is being adapted to study problems in
