Bio-inspired Polydopamine Treatment and Nanosilver Formation for Antibacterial Uses

Chiu Y.-H., Li M.-C., Wu K.-M., Chung Y-C, National University of Kaohsiung, TW

In the study, we employed the mussels’ glue component—dopamine and its excellent reducing ability toward silver ions, to create a novel antibacterial effect on a facial mask surface so as not to add harmful antiseptics [...]

Bio-inspired Nanosucker Structures for Dry Adhesives

Chang W.-Y., Wen Y.-P., Chung Y-C, National University of Kaohsiung, TW

We present a facile lithographic nanosphere production process by laminating a nanosphere monolayer with a UV resin and applying various gentle solvent treatments to produce “bottom-up” and “bottom-down” non-close-packed patterns, and generate nanosuckers for adhesion.

The Structure and Properties of ta-C Film with Dispersion of Incident Beam Energy

Lee K-R, Lee S-C, Lee S-H., Kim T.-Y., Lee K-R, Lee S-C, Lee S-H., Chung Y-C, Brenner D.W., Lee K-R, Lee S-C, Lee S-H., Korea Institute of Science and Technology, KR

We investigated the structural properties of ta-C film as a function of the dispersion in the incident kinetic energy. The ta-C films were produced on a diamond (100) surface by the bombardment of 3, 000 [...]

Phosphorylcholine-protected Nanoparticles Functionalized with Both Magnetic and Photoluminescent Properties

Chung Y-C, Chen C-J., National University of Kaohsiung, TW

We prepared the magnetite core coated with nano-graded ZnS shell to display superparamagnetic and photoluminescent properties. By adsorbing the phosphorylcholine-ended thiol to stabilize the core-shell nanoparticles, the particles can be well-dispersed in aqueous buffer solution [...]

Ab Initio Calculations on Magnetic Properties of Diluted Magnetic Semiconductors

Kim H., Kim Y-S, Kim H., Kim Y-S, Chung Y-C, Hanyang University, KR

Some diluted magnetic semiconductors (DMS), in which magnetic elements are substituted for a small fraction (~5%) of host elements in a semiconductor lattice, show ferromagnetism, and thus possess potential applicability in spintronics. To obtain quantum-mechanical [...]
