Radon Mitigation Efficiency using Nano-size Carbon Colloid

Cho , S.Y., Jung, K.S., Kim, D-H., Kim, M-J, Kim, S-H, Lee, K.H., Yonsei University, KR

Radon is classified as the second leading cause of lung cancer in the US. There have been plenty of trials to mitigate indoor radon gas which penetrated through the floor cracks, building materials and groundwater [...]

A 20 µm Movable Micro Mobile

Jeon, J., Kim, M-J, Lee, J.B., The University of Texas at Dallas, US

We present design, fabrication, and characterization of an extremely small (20x14 µm) movable 3D micro vehicle. The micro mobile was fabricated using a combination of focused-ion-beam (FIB) for micro/nano parts production, atomic layer deposition (ALD) [...]

Effects of the Addition of TiO2 Nanoparticles for Polymer Electrolytes Based on Porous Poly(vinylidene fluoride-co-hexafluoropropylene)/Poly(ethylene oxide-co-ethylene carbonate) Membranes

Chung, J.W., Jeon, J-D, Kim, M-J, Kwak, S-Y, Seoul National University, KR

In order to ameliorate the performance of polymer electrolytes, we report on a novel solvent-free polymer electrolyte filled with viscous poly(ethylene oxide-co-ethylene carbonate) (P(EO-EC)) into a porous membrane. In addition, to enhance the conductivity and [...]

Characteristics of Bacterial Pumps in Microfluidic Systems

Breuer, K.S., Kim, M-J, Brown University, US

In this paper we show that (i) the flow-deposition of bacteria can successfully create a live bacterial carpet to generate local fluid motion inside a microfabricated system; (ii), that the carpet-activated microfluidic system can be [...]
