Synthesis and characterization of copper oxide decorated zinc oxide nanorods

Lim S.K., Hong S.H., Hwang S.H., Kim H-S, Kim S., Lee D.J., Kim H-S, Kim S., DGIST(Daegu Gyeongbuk Institute of Science & Technology), KR

One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for [...]

Fabrication Processes and Multi-functional Properties of Carbon Nanotube/Inorganic Nanocomposites

Hong S.H., Korea Advanced Institute of Science and Technology, KR

Molecular level mixing process was developed for the fabrication of homogeneous carbon nanotube(CNT)/Inorganic nanocomposites instead of the conventional powder mixing process in order to solve the agglomeration of CNTs and weak interfacial bonding between CNTs [...]

Mechanical and Electrical Properties of CNT/Inorganic Nanocomposites by Molecular Level Mixing Process

Hong S.H., Korea Advanced Institute of Science and Technology, KR

One of the emerging applications of CNTs is the reinforcement of composite materials to overcome the performance limits of conventional materials. However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix [...]

Synthesis of Carbon Nanotubes by Decomposition of Hydrocarbon Using an Arc-Jet Plasma

Choi S., Choi S.S., Nam J.S., Choi S., Choi S.S., Lee C.M., Kim J.I., Hong S.H., Seoul Nationl University, KR

We present a method to produce carbon nanotubes by decomposition of hydrocarbons using an arc-jet plasma of high temperature (500020000 K). Carbon nanotubes are continuously produced in a floating condition by introducing a hydrocarbon gas [...]
