Superhydrophobic and Superhydrophilic Nanocomposite Coatings for Preventing Microbial Adhesion on Liquid Food Contact Surface

Rungraeng N., Yoon S-H, Song W., Jun S., University of Hawaii at Manoa, US

Pathogenic microbes in biofilm matrix increase the potential of cross-contamination with processed food products, subsequently resulting in food borne disease outbreaks. Prevention of bacterial adhesion on food contact surfaces will have a massive impact in [...]

Processing Parameters Affecting Nanoinjection Molding

Srirojpinyo C., Yoon S-H, Lee J., Sung C., Mead J.L., Barry C.M.F., University of Massachusetts-Lowell, US

Although micro parts and features are routinely molded, the performance of polymer melts is not well understood when the part wall thickness is less than 1 mm. In this study, the effects of molding conditions [...]

Investigation of Tooling Surfaces on Injection Molded Nanoscale Features

Yoon S-H, Srirojpinyo C., Lee J., Sung C., Mead J.L., Barry C.M.F., University of Massachusetts at Lowell, US

The composition and surface properties of tooling materials become more critical as the size of the molded features decreases [1, 2]. This work investigates the effect of tooling surfaces with micro and nanoscale features. These [...]

A Novel Scheme of Mesh Generation from an Arbitrary Topography for MEMS Analysis

Kwon O-S, Yoon I-T, Yoon S-H, Yoon S-I, Yoon I-T, Yoon S-H, Yoon S-I, Ha T-S, Yoon I-T, Yoon S-H, Yoon S-I, Won T-Y, Inha University, KR

Binding energies for an exciton (X) trapped in the two-dimensional quantum dot by a charge impurity located on the z axis at a distance from the dot plane are calculated by using the method of [...]
