CNT reinforced Aluminum composite

Moon S., Lee D., Jung S., Applied Carbon Nano Technology Co Ltd, KR

Carbon nano tube(CNT) is known as a pioneer material for new century because of its excellent physico-chemical properties. Despite the good properties of CNT itself, CNT's application is restricted by its size problem. We have [...]

Ti-based nanocrystallites formation by high-energy milling

Kwon H., Jung S., Cho S.W., Kil D.S., Kim J., Roh K.M., Lim J.W., Korea Institute of Geoscience and Mineral Resources, KR

There are many researches for the solid-solution to prepare the materials with the properties which pure materials do not have. However, basically, it was difficult to synthesize the solid-solution phase because of high activation energy [...]

A field-emission X-ray source using an anisotropically focused electron beam

Jung S., Kim D., Seol S.K., Korea Electrotechnology Research Institute, KR

A field-emission X-ray source for dental imaging with an anode voltage of 70 kV and an anode current of more than 1 mA was designed and assembled using an anisotropically focused electron beam. With up [...]

Periodic Nanowell Array using Template-Assisted Nanosphere Lithography

Jung S., Lee J., Seoul National University, KR

This paper presents a template-assisted nanosphere lithography(NSL) to obtain high-quality crystal in regularity and coverage(Figure 1). A periodic array of 100-nm deep, 360-450 nm wide nano-trenches was fabricated by nano imprint lithography(NIL), and used as [...]
