Direct Visualization of Perm-Selective Ion Transportation
Wonseok Kim, Jungeun Lee, Gun Yong Sung +1
Perm-selective ion transportation in a nanoscale structure has been extensively studied with aids of nanofabrication technology for a decade. While theoretical and experimental adv…
Experimental Verification of Overlimiting Current by Surface Conduction and Electro-osmotic Flow in Microchannels
Sungmin Nam, Inhee Cho, Joonseong Heo +4
Possible mechanisms of overlimiting current in unsupported electrolytes, exceeding diffusion limitation, have been intensely studied for their fundamental significance and applicat…
Superconducting properties of well-shaped MgB2 single crystal
Kijoon H. P. Kim, Jae-Hyuk Choi, C. U. Jung +11
We report measurements of the transport and the magnetic properties of high-quality, sub-millimeter-sized MgB2 single crystals with clear hexagonal-plate shapes. The low-field magn…
Microstructure of the highly dense MgB2 Superconductor by transmission electron microscope
Gun Yong Sung, Sang Hyeob Kim, JunHo Kim +8
The microstructure of the MgB2 superconductor sintered at high temperature under a high pressure of about 3 GPa was investigated by using a high-resolution transmission electron mi…
