Bearing life prediction on the basis of run-out using accelerated life testing coupled with numerical analysis

Lee N.R., Hwang S.Y., Kim N., Sogang University, KR

Wear is one of the most important factors affecting roller bearing performance and in determining bearing life-time. Bearing life has traditionally been defined by the onset of spalling (ISO 281), but this definition does not [...]

FE Simulation of material removal and surface properties for EDM during single and multiple spark occurrences

Lim H.J., Domblesky J.P., Kim N., Hwang S.Y., Sogang University, KR

EDM represents an effective machining process for hard-to-machine materials. Although EDM has many advantages, it lacks well-developed technological base and level of fundamental understanding that characterizes other metal cutting technologies. This has limited the development [...]

Model Study for Thermal Deformation and Creep Behavior of Polymers Considering Moisture Diffusion

An T.G., Lim Y., Kim N., Sogang University, KR

ABS(Acrylonitrile-Butadiene-Styrene) polymer is viscoelastic materials which are subject to permanent deformation when exposed to certain temperatures and humidity levels for long periods of time. In this paper, this phenomenon was defined as a creep phenomenon [...]

Phosphate recognition using multilayer charged thin films containing zirconium (Zr) ions for biochip applications

Lee M., Kim J.H., Kim N., Kim S-H, Kim J.H., Kim N., Kim S-H, Shin C.-J., Koh K., Kim J.H., Kim N., Kim S-H, Ajou University, KR

The phosphate residue plays an important role as not only the structural component of DNA and lipid but also the activation signal of protein in the cellular signaling pathways. Therefore, the selective recognition for the [...]

Microfluidic Platforms with Micro- and Nanopore Membranes and in situ Formation of Lipid Bilayer in the Microfluidic Platform

Choi J., Kim N., Park S., Louisiana State University, US

Artificial lipid bilayer membranes have come into the spotlight as topics of fundamental properties of biomaterials, targets for drug discovery and safety screening, and analytic platforms for characterization and orientation discrimination of polynucleotide molecules. Lipid [...]
