Uniformly Distributed Metal Nano-particles in Various Sized Porous Catalytic Supports by NPP Process

Lee C., Lee J-H., Lee C., Lee J-H., Kang B.K., Kaji H., Hayashi M., Koh S.K., GL Materials, KR

2~10 nm sized metal nano-particles were uniformly loaded in porous activated carbon (AC) support and 10~100 nm sized metal nano-particles were completely covered on the surfaces of air flow channels of porous ceramic monolith. Metal [...]

A Study of Particle Size Distribution in NPP process

Lee C., Lee J-H., Lee C., Lee J-H., Koh S.K., Kaji H., Haysashi M., GL Materials, KR

Noble nanoparticles were fabricated on glucose powder by NPP process, in which nanoparticles were formed on the rotating powder in barrel by using conventional PVD system. A 500 um glucose powders were selected as the [...]

Prevention of Coalescence Stage from Nuclei at Initial Growth of Thin Film by Substrate Rotation in Physical Vapour Deposition

Koh S.K., Lee J-H., Han Y.G., Cho J-S, Joo J.H., Kralkina E.A., P&I Corp., KR

A method of nanoparticle fabrication in physical vapor deposition was introduced. Metal were deposited on the powdery substrate which were stirred by rotors. Particle size and prodcuction rate of metal nano particles were controlled by [...]

Continuous Optimization Method for the Sequence Design of Protein Models Consisting of Multiple Monomer Types

Koh S.K., Ananthasuresh G.K., Yang X., Saven J., Indian Institute of Science, IN

In our earlier work, we had introduced continuous modeling of two discrete states (H: Hydrophobic; P: Polar) of the amino acid monomers and presented a deterministic continuous optimization method to design the sequence that minimizes [...]
