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]. [...]

In situ transesterification of wet microalgae under acid catalysts

Lee J.W., Kim B., Im H., Korea Advanced Institute of Science and Technology, KR

Microalgae can be categorized to be the third generation of promising biofuel resources and can utilize carbon dioxide from flue gas as a nutrient source and accumulate lipids inside cells. They grow faster than any [...]

Electrocatalytic activity of core-shell carbon-metal nanocomposites derived from carbon dioxide

Lee J.W., Zhang J., Kim Y., Byeon A., Korea Advanced Institute of Science and Technology, KR

The polymer electrolyte fuel cells(PEFCs) have demonstrated one of promising devices to convert chemical energy of fuels with high energy efficiency, high power density, and low environment impact. Despite wide applications in many areas, the [...]

Fabrication Processes and Multi-functional Properties of Carbon Nanotube/Inorganic Nanocomposites

Hong S.H., Korea Advanced Institute of Science and Technology, KR

Molecular level mixing process was developed for the fabrication of homogeneous carbon nanotube(CNT)/Inorganic nanocomposites instead of the conventional powder mixing process in order to solve the agglomeration of CNTs and weak interfacial bonding between CNTs [...]

Mechanical and Electrical Properties of CNT/Inorganic Nanocomposites by Molecular Level Mixing Process

Hong S.H., Korea Advanced Institute of Science and Technology, KR

One of the emerging applications of CNTs is the reinforcement of composite materials to overcome the performance limits of conventional materials. However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix [...]

Sirna Nanomedicines for Cancer Gene Therapy

Kim S-H, Park T.G., Korea Advanced Institute of Science and Technology, KR

We developed a polyelectrolyte complex (PEC) micelle-based delivery system for treatment of prostate cancer. A PEGylated siRNA targeting human vascular endothelial growth factor (hVEGF) was synthesized. The hVEGF expression was almost completely inhibited in vitro [...]

Fast and Easy Detection System of Protein Glycosylation by Using Resonant Energy Transfer between Nanoparticles

Oh E., Lee D., Kim H-S, Korea Advanced Institute of Science and Technology, KR

We construct the new glycosylation detection system using Resonance Energy Transfer (RET) between gold nanoparticles (AuNPs) and semiconductor quantum dots (QDs). RET can be induced by biomolecular interactions between concanavalin A (conA)-conjugated AuNP (conA-AuNP) as [...]
