Preparation of ion group functionalized diblock copolymers and examination of their thermogelling properties

Lee B.K., Kwon D.Y., Kwon J.S., Park J.H., Kwon D.Y., Kwon J.S., Kim J.H., Kim M.S., Oh S.H., Kim J.H., Kim M.S., Ajou University, KR

To investigate thermogelling behavior, in this study, methoxy polyethylene glycol-b-[poly(ε-caprolactone)-ran-poly(6-chloride-ε-caprolactone) (PCL-ran-PfCL)] (PCL-Cl) diblock copolymers were designed such that the PfCL content in the PCL segment was varied. The PCL-Cl diblock copolymers were derivatized by introducing [...]

Silver Nanoplate Array for Vertically Aligned P-type ZnO Nanorods

Park J.H., Lee T.I., Myoung J.-M., Yonsei University, KR

In this presentation, a monolayer of silver nanoplate is introduced as an epitaxial template and doping source for vertically aligned p-type ZnO nanorods. Silver nanoplates were synthesized through room temperature polyol process and the monolayer [...]

Reduction-sensitive hyaluronic acid nanoparticles for targeted intracellular deliery of doxorubicin

Saravanakumar G., Shin J.M., Um W., Park J.H., Sungkyunkwan University, KR

Disulfide-containing HA dodecyl conjugates (HA-SS-DDTs) were synthesized using the facile thiol-exchange reaction as the carrier for intracellular delivery of doxorubicin (DOX). Owing to its amphiphilicity, HA-SS-DDT could form self-assembled nanoparticles in an aqueous condition. The [...]

In-Situ Assessment of Wafer-Level Hermeticity by Micromembrane Technique

Yang C.-M., Jung H., Park E.M., Park J.H., Park E.M., Park J.H., Kim H-Y, Lee K-R, National Nano FabCenter, KP

Generally, the quantitative hermeticity of Wafer level Vacuum Packaging (WLVP) has been evaluated by integration of pirani gauge vacuum senses. But, this requires complex fabrication process and higher chip cost. In this work, hermeticity and [...]

Optical band gap energy of Er-doped TiO2 thin films

Lee D.Y., Lee I.G., Park J.H., Kim Y.H., Lee D.Y., Lee I.G., Daelim University, KR

Er-doped TiO2 thin films(0~1.0 mol% Er) having a thickness of 400 to 1200 nm were spin coated onto FTO glass substrate by varying PVP concentration. The optical properties of thin films was examined by glancing [...]

Nanoscale structure and property changes in collagen fibrils on the extracorporeal shockwave therapy applications of the rat Achilles tendon injury

Choi S., Lee G.J., Chon J., Chae S.-J., Yoo S.-D., Park H.K., Park J.H., Kim K.S., Park H.K., Park J.H., Kyung Hee University, KR

Extracorporeal shockwave therapy (ESWT) is popular in the treatment of musculo-skeletal injuries. However, the mechanism by which such therapy might have an effect on tendon injury is unknown. The Achilles tendons are mainly composed of [...]

Measured and predicted performance of a micro-thermophotovoltaic device with a heat-recirculating micro-emitter

Park J.H., So J.S., Moon H.J., Kwon O.C., Sungkyunkwan University, KR

A new configuration of a 1-10 W micro-thermophotovoltaic (micro-TPV) device with a heat-recirculating micro-emitter is studied experimentally and computationally. In the micro-TPV device thermal energy is directly converted into electrical energy through thermal radiation without [...]
