Electrospun Nanofiber Membranes and Electrodes for Fuel Cells

Wycisk R., Ballengee J., Park J.W., Brodt M., Pintauro P.N., Vanderbilt University, US

The focus of our research group has been on the use of electrospinning for the fabrication of nanofiber membranes and electrodes for PEM fuel cells. We have demonstrated dramatic improvement in fuel cell performance and [...]

Optimizing Quantum Dot-Conjugated Immunoliposomes for Cancer Diagnostics and Targeted Therapeutics

Weng K.C., Noble C.O., Papahadjopoulos-Sternberg B., Chen F.F., Park J.W., UCSF Comprehensive Cancer Center, US

A multifunctional nanoparticle that combines the optical properties of luminescent quantum dots (QDs) and therapeutic modality of immunoliposomes (ILs) has been developed. Carboxylate-derivatized QDs cross-linked with amino- poly(ethylene glycol)-functionalized liposomes were modified with anti-human epidermal [...]

DNA-DNA Interaction on Dendron-Functionalized Sol-Gel Silica Films Followed with Surface Plasmon Fluorescence Spectroscopy

Kwon S.H., Hong B.J., Park H.Y., Park J.W., Knoll W., Park H.Y., Park J.W., Center for Integrated Molecular System., KR

Since we observed that dendron-assembled surface providing a proper spacing between immobilized DNAs showed high single nucleotide polymorphism discrimination efficiency for DNA microarrays(1), the nanoscale-controlled surface is examined with surface plasmon field-enhanced fluorescence spectroscopy (or [...]

Electrokinetic Instability Mechanism of Double-layered Miscible Fluids with Different Electrolyte Concentrations in DC Electric Field

Park J.W., Kang K.H., Huh K.Y., Pohang University of Science and Technology, KR

Interfacial instability has recently been observed for DC-powered electroosmotic flow by Chen and Santiago [1]. So far, no plausible explanation has yet been made since the phenomenon is contrary to common belief of laminar flow [...]
