1. X-Ray Scattering Study on the Damage in Fibers Used in Soft Body Armor After Folding
Published: 9/21/2012
Authors: Haruki Kobayashi, Walter G McDonough, Joy P Dunkers, Scott A Wight, Hae-Jeong Lee, Jae Hyun Kim, Amanda Lattam Forster, Kirk D Rice, Gale Antrus Holmes

2. The Effects of Folding on High Strength Fibers Used in Soft Body Armor
Published: 1/23/2012
Authors: Haruki Kobayashi, Walter G McDonough, Joy P Dunkers, Jae Hyun Kim, Hae-Jeong Lee, Scott A Wight, Amanda Lattam Forster, Kirk D Rice, Gale Antrus Holmes
Abstract: Poly (p-phenylene benzobisoxazole) (PBO) fibers have been used in soft body armor (SBA) because of their high mechanical strength. However, there was an unexpected failure of a first responder‰s SBA which was composed of PBO fiber that was in service ...

3. The Effect of Folding on the Mechanical Properties and Internal Structures of Fibers Used in Ballistic Applications
Published: 7/18/2011
Authors: Haruki Kobayashi, Walter G McDonough, Hae-Jeong Lee, Jae Hyun Kim, Amanda Lattam Forster, Kirk D Rice, Gale Antrus Holmes
Abstract: The failure of a first responder‰s soft body armor (SBA) composed of poly (p-phenylene benzobisoxazole) (PBO) fibers has prompted researchers to assess the long-term durability and effectiveness of current and future SBA products. Based on existing d ...

4. The Effect of Folding on the Internal Structure of Ballistic Fibers
Published: 5/26/2011
Authors: Haruki Kobayashi, Walter G McDonough, Hae-Jeong Lee, Jae Hyun Kim, Amanda Lattam Forster, Kirk D Rice, Gale Antrus Holmes
Abstract: In one of our previous studies, the mechanical properties of poly (p-phenylene benzobisoxazole) (PBO) fibers were degraded when the fibers were folded. When we examined poly (p-phenylene terephthalamide) (PPTA) fibers, we did not find a similar drop ...

5. Differences in Polydimethylsiloxane Modification Methods Affect Laminin Deposition and Smooth Muscle Cell Proliferation
Published: 4/13/2011
Authors: Joy P Dunkers, Hae-Jeong Lee, Marvi Matos, Lisa Pakstis, Juan M. Taboas, Steven D Hudson, Marcus T Cicerone
Abstract: When culturing cells on flexible surfaces, it is important to consider extracellular matrix treatments that will remain on the surface under mechanical strain. Here we investigate differences in laminin surfaces that were deposited on oxidized PDMS ...

6. Preparation and Characterization of Physical Gels based on Ionic Liquid and Poly(vinyl alcohol)
Published: 2/28/2011
Authors: Joonsung (Joonsung) Yoon, Hae-Jeong Lee, Christopher M Stafford
Abstract: We report the preparation and characterization of physical gels using mixtures of poly(vinyl alcohol) (PVOH) and a high melting ionic liquid (IL), 1-ethylpyridinium bromide. Similar to PVOH hydrogels, these mixtures show elastic responses in uniaxial ...

7. Differences in PDMS Modification Affect Laminin Deposition and Smooth Muscle Cell Response
Published: 8/16/2009
Authors: Joy P Dunkers, Hae-Jeong Lee, Marvi Matos, Lisa Pakstis, Juan M. Taboas, Steven D Hudson, Marcus T Cicerone
Abstract: When culturing cells on flexible surfaces, it is important to consider extracellular matrix treatments that will remain on the surface under mechanical strain. Here we investigate differences in laminin surfaces that were deposited on oxidized PDMS ( ...

8. Characterization of Laminin on Silanized Polydimethylsiloxane
Published: 8/21/2008
Authors: Joy P Dunkers, Lisa M Hughes, Hae-Jeong Lee, Marvi Matos, Marcus T Cicerone
Abstract: In this work, we characterize a protein surface on a flexible polydimethylsiloxane substrate (PDMS) capable of undergoing strain. We compare the results from two different surface treatments: physically adsorbed laminin on PDMS and laminin deposited ...

9. Quantitation of Laminin Adsorbed onto Flexible Substrates Using Various Treatment Protocols
Published: 6/25/2008
Authors: Hae-Jeong Lee, Marvi Matos, Lisa Pakstis, Marcus T Cicerone, Joy P Dunkers
Abstract: There is considerable interest in how cells respond to mechanical stimuli, from the ligands used to transmit the stimulus to the signaling pathways initiated to the proteins expressed upon phenotype change. Our work focuses on using a flexible substr ...

10. Self-Sealing Nanoporous Low-k Dielectric Patterns Created by Nanoimprint Lithography
Published: 4/15/2008
Authors: Hyun W. Ro, H Peng, Ken-ich Nihara, Hae-Jeong Lee, Eric K Lin, Alamgir Karim, D Gidley, Hiropshi Jinai, Do Y. Yoon, Christopher L Soles
Abstract: In this letter we describe how highly porous nanostructures can be directly printed into a poly(methylsilsequioxane) (PMSQ)-based organosilicate film, with high pattern fidelity, and develop the measurement infrastructure to quantitatively evaluate ...
