A Predictive Resistive RAM Compact Model with Synaptic Behavior for Circuit Simulations

Chiang, M-H, Hsu, C.-H., Lee, J.W., National Cheng Kung University, TW
Artificial intelligence has come to its new era with the fast growth of machine learning algorithm. However, the conventional Von-Neumann architecture could consume excessive energy during the training process. At this moment, the memristor sheds [...]

Development of a highly durable anode support for solid oxide fuel cell

Lee, J.W., Lee, S.B., Lim, T-H, Mehran, M.T., Park, S-J, Song, R-H, Korea Institute of Energy Research, KR
Solid oxide fuel cells are well known to be highly efficient and clean energy conversion devices for stationary and portable power generation. The ceramics based SOFC’s operate at high temperatures (>700 °C) and the durability [...]

In situ transesterification of wet microalgae under acid catalysts

Im, H., Kim, B., Lee, J.W., Korea Advanced Institute of Science and Technology, KR
Microalgae can be categorized to be the third generation of promising biofuel resources and can utilize carbon dioxide from flue gas as a nutrient source and accumulate lipids inside cells. They grow faster than any [...]

Electrocatalytic activity of core-shell carbon-metal nanocomposites derived from carbon dioxide

Byeon, A., Kim, Y., Lee, J.W., Zhang, J., Korea Advanced Institute of Science and Technology, KR
The polymer electrolyte fuel cells(PEFCs) have demonstrated one of promising devices to convert chemical energy of fuels with high energy efficiency, high power density, and low environment impact. Despite wide applications in many areas, the [...]

MD Simulations on the Momentum Transfer to Nano Contaminant Particle on Wafer Surface in Collisions with Cleaning Bullets

Choi, M.S, Lee, J.W., POSTECH, KR
This study aims to clarify the basic mechanism through MD simulations on momentum transfer during collisions between target contaminant and cleaning bullet particles both in the nanometer size range. Even in conditions where the contaminant [...]

Simultaneous removal of nano-sized contaminant particles with multi-modal size distribution using hybrid particle beams

Kim, I., Lee, J.W., POSTECH, KR
The removal of contaminant particles(CPs) as small as 10nm from wafer surface is essential in successful fabrication of nano-scale devices. The supersonic particle beam technique using nano-sized volatile bullet particles(BPs) was extremely effective in removing [...]

Removal of 10-nm contaminant particles from a wafer surface with supersonic CO2 particle beam

Kim, E-J, Kim, I-H, Lee, J.W., POSTECH, KR
Contaminant control is becoming a major issue of nano-scale devices. Cryogenic aerosol beam using micron-sized aerosol particles has long been successfully used to remove contaminant particles (CPs) down to 50nm, and supersonic particle beam using [...]

Structural and Mechanical Changes in Heart Mitochondria of Rat by AFM

Chae, S.-J., Ha, S.J., Kang, S-W, Kim, W., Kim, Y., Lee, G.J., Lee, J.W., Park, H.K., Kyung Hee University, KR
Mitochondria play critical roles in both the life and death of cardiac myocytes. Various factors such as loss of ATP synthesis and increase of ATP hydrolysis, impairment in ionic homeostasis, formation of reactive oxygen species [...]

Cleaning 10nm ceramic particles by the supersonic particle beam

Hwang, K., Kim, I., Lee, J.W., POSTECH, KR
Cryogenic aerosol beam using micron-sized aerosol particles has long been successfully used to remove contaminant particles down to 50nm, and supersonic particle beam using particles smaller than 100nm lowered the limit of cleaning down to [...]

Rhodamine B Isothiocyanate-Modified Ag Nanoaggregates on Dielectric Beads: A Novel Surface-Enhanced-Raman-Scattering and Fluorescent Imaging Material

Jang, H.J., Kim, K., Lee, H.B., Lee, J.W., Seoul National University, KR
Ag-deposited silica and polystyrene beads are efficient surface-enhanced-Raman-scattering (SERS) substrates that can be used as core materials of SERS-based biosensors. In this work, we report that once rhodamine B isothiocyanate (RhBITC) is adsorbed onto them, [...]
