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 [...]

Synthesis of hollow silica particles with tunables ize,shell thickness,and morphology

Kim J., Lee J., Chang H., Choi J.W., Jang H-D, Kim J., Korea Institute of Geoscience and Mineral Resources, KR

Here, we provide simple methods to modify the particle size, shell thickness, and the morphology of hollow silica particles (HSPs). To synthesize the HSPs, we adopted polystyrene (PS) particles as a sacrificial template. Size tune [...]
