Research Interests

  • Developing new metrology to characterize nano-structures in thin film and membrane using X-ray reflectivity (SXR), small angle x-ray scattering (SAXS), grazing incident small angle x-ray scattering (GI-SAXS) and small angle neutron scattering (SANS)
  • Study on the effects of confinement geometry on crosslinking density of UV nanoimprint resist
  • Developing advanced characterization methods for determining regular and irregular nano- and micro- scale patterns using SXR as a pattern shape metrology
  • Developing novel resist for high resolution e-beam lithography and fabricating reliable nano-patterns using newly developed resist 
  • Structural characterization of porous thin films including porosity, average pore size, pore connectivity, pore size distribution, matrix density, average film density, and water uptake using SXR, SAXS, GI-SAXS, and SANS
  • Characterizing surface and interfacial structures and density depth profiles of thin films

The Effects of Folding on High Strength Fibers Used in Soft Body Armor

Haruki Kobayashi, Walter G. McDonough, Joy P. Dunkers, Jae Hyun Kim, Hae-Jeong Lee, Scott A. Wight, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
Poly (p-phenylene benzobisoxazole) (PBO) fibers have been used in soft body armor (SBA) because of their high mechanical strength. However, there was an

The Effect of Folding on the Internal Structure of Ballistic Fibers

Haruki Kobayashi, Walter G. McDonough, Hae-Jeong Lee, Jae Hyun Kim, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
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
