Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Kim H.W., Kim J.W., Kim T.I., Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Seoul National University, KR

Composite substrates are considered as prospective matrix to populate and support cells in the bioengineering field. Synthetic degradable biomaterials, including poly(lactic acid) (PLA) and tricalcium phosphate (TCP), are widely used for matrix scaffold. In present [...]

Effect of nano-sized silica particle for high insulation resistance on the surface of non-oriented electrical steel

Kim J.W., Kwon M.S., Han C.H., POSCO, KR

The effect of a nano-sized silica particle on the surface insulation resistivity of non-oriented electrical steel sheet was investigated. Several kinds of nano-sized colloidal silica were mixed to the chromium-free coating solution, which is consisted [...]

Transparent film sensor for strain measurement using carbon nanotube networks

Chang W.-S., Song S.-A., Kim J.H., Kim J.W., Kim J.H., Kim J.W., Lee H-C, Han C-S, Korea Institute of Machinery and Materials, KR

Since the carbon nanotube was reported by Iiijima, it has been intensively studied due to their great potential in nanoelectronics and nanomechanical devices. Recently, experimental results show that sing-wall carbon nanotubes (SWCNTs) change their electronic [...]
