Physical Properties of Ferrite Nanocomposites Based On Nylon-66

Kim B.C., Kim M.H., Kim B.C., Kim M.H., Hanyang University, KR

The ferrite nanoparticles acted as a nucleating agent, leading to a small degree of supercooling. However, above a critical loading level (1 wt %), the nanoparticles in the polymer matrix might restrict the chain mobility [...]

Immobilization of Polydiacetylene Sensor on Solid Substrate

Lee Y.B., Kim J-M, Park K.H., Son Y.G., Ahn D.J., Kim J-M, Hanyang University, KR

We have prepared diacetylene monomers and immobilized the resulting self-assembled diacetylene liposomes onto the glass substrates. Fine fluorescent images were obtained when the immobilized liposomes were irradiated with UV light through a photomask followed by [...]

Direct Electrochemical Reduction of CuO Nano Particles to Cu Nano Particles in NaCl Solution

Hwang G-H, Han W-K, Hong S-J, Choi J.W., Kang S-G, Hanyang University, KR

Copper nanoparticles are widely used material. However many reactive metals are difficult to produce without complex and expensive procedures. For low cost and mass production, the electrochemical reduction is a convenient technique to manufacture metal [...]

Controlling Colorimetric Reversibility of Nanostructured Polydiacetylenes

Lee C.H., Lee J.S., Lee C.H., Lee J.S., Park H-W., Lee C.H., Lee J.S., Ahn D.J., Kim J-M, Hanyang University, KR

Polydiacetylene liposome has specific color change of blue to red upon various kinds of stimuli. Stimuli can be a antigen-antybody, thermal stimuli and Ph change and even physical contact. From these charecteristics polydiacetylene used a [...]

Nano-structured Chitosan Self-Aggregates as a Drug Delivery Carrier

Bae M.S., Kwon I.C., Jeong S.Y., Lee K.Y., Hanyang University, KR

A number of novel delivery systems have been developed including the entrapment of drugs, proteins, antigens, or genes in small vesicles or within polymeric matrices. Colloidal delivery systems such as liposomes, microemulsions, and polymeric micelles [...]

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 [...]
