Morphological change from nano-cube to nano-sphere by addition of Ni to W in RF thermal plasma synthesis

Kim Y.M., Na H., Lee B.J., Lee W., Lee B.J., Lee W., Hwang N.M., Choi H., Korea Institute of Industrial Technology, KR

Pure W and W-Ni nano-particles were effectively synthesized by feeding thermo-physically favorable oxide feedstock micro-powder into argon-hydrogen thermal plasma. During the process, feedstock particle underwent a vaporization, reduction, and condensation pathway. Significant amount of nano-cube [...]

Preparation and characterization of release behavior for hydrophilic drug loaded alginate nanohydrogels

Lee H.Y., Lee S.M., Lee H.Y., Lee S.M., Kim M.K., Kim Y.M., Kim M.K., Kim Y.M., Sohn S-O, Ghim H-D, Kyungpook National University, KR

Recently, there have been considerable interests in developing biodegradable nanoparticles as effective drug delivery devices. Alginate is one of the hydrophilic natural polymers having biodegradability and biocompatibility. It has possibility to apply in the controlled [...]

Fabrication of 3-Dimesional Cu Coaxial Cylinder using Porous Silicon MEMS Technology

Eun D.S, Kim Y.M., Bae CH.H., Lee J-H., Kyungpook National University, KR

Therefore, this paper reports 3-dimensional Cu coaxial cylinder with a thick OPS(oxidized porous silicon) in low resistivity silicon for application of microwave and RF integrated circuit technology. A novel on-chip 3D coaxial cylinder was fabricated [...]
