Modeling of polypeptide- and polymer-conjugated nanoparticles for drug delivery application

Lee H.K., Dankook University, KR

Nanoparticles such as liposomes, dendrimers, and carbon nanotubes have many potential biomedical applications as antitumor therapeutics and drug delivery. These applications require the interaction of those with cell membranes, thus interactions of nanoparticles, polymers, and [...]

Concrete crack-healing materials using biocalcification by ureolytic bacteria isolated in marine environment: An overview

Kim H-Y, Son H.M., Lee H.K., Korea Advanced Institute of Science and Technology, KR

Micro-cracks on the surface of concrete structures frequently occur due to external force and shrinkage [1]. The deterioration of concrete durability is accelerated by the penetration of moisture and chemicals into microcracks and pores [2]. [...]

Electromagnetic wave shielding effectiveness of SWNT-coated, transparent, conducting panels

Nam I.W., Lee H.K., Sim J.B., Choi S.M., KAIST, KR

Needs for electromagnetic wave shielding/absorbing have been increased in order to prevent electromagnetic interference, eavesdropping, and harmful effects to human bodies (Chung, 2001; Kim and Lee, 2008). Single-walled carbon nanotubes (SWNTs) have been well-known for [...]

Experiments to Investigate Electromagnetic Shielding Performance of Polyaniline-Coated Thin Films

Kim B.R., Lee H.K., Korea Advanced Institute of Science and Technology (KAIST), KR

Many studies on electromagnetic wave shielding/ absorbing materials have been performed. In particular, studies of novel materials have been carried out as an alternative to conventional shielding materials such as metallic materials. Recently, the investigation [...]

Anodic aluminum oxide-based capacitive humidity sensor integrated with micro-heater

Kim Y.D., Jung B.B., Lee H.K., Lee K.H., Lee H.K., Lee K.H., Park H.C., Pohang University of Science and Technology, KR

AAO(Anodic Aluminum Oxide) film is fabricated as a sensing material of capacitive humidity sensors. Because AAO films have a lot of nano-size pores, many water vapors can be absorbed. The size of a pore diameter [...]
