Fabricating semiconductor thin films by magnetron sputter

Topics: 1. Thin film deposition (Mainly oxide layers, e.g. TiO2, CuxOy) by reactive magnetron sputtering 2. Photocatalytic hydrogen production by TiO2 nanostructures with co-catalysts (Pt, Pd, Au) 3. Synthesis (fabrication) of TiO2 nanostructures (nano sheets, nano tubes and nano cubes) Specialties 1. Fabrication (Synthesis) : TiO2 nanostructures by means of reactive DC magnetron sputtering, hydro/solvothermal, anodization, doctor blading methods 2. Photo(electro)catalytic Reaction: Hydrogen Evolution Reac

Title: Development of Precise Parallelism of Narrow-gap Rotational Rheometer and its Examinations The project is all about rheometer modifications (soft/hard ware) for the better measurement, understanding the rheological properties of target materials.

Supported by Brain Busan 21 Project (BB21), I had worked as a scientific researcher for CO2 gas hydrate formation and deformation in order to understand mechanism of methane gas hydrate in the deep oceans and to develop techniques of its extraction as a future green energy source.

As an industrial internship course, I had worked in Henkel Korea (Busan). 1. Development of water-based adhesives for sport shoes: Ph control, viscosity control, adhesion improvement, wettability improvement. 2. Characterization (or test) of the adhesives: viscosity, adhesion strength, stability tests in humid condition and water immersion.
