Bi-Layer Graphene Nanoribbon Memory with Graphene Nanoflake Shuttle

Kwon O-K., Kang J-W, Lee J-H., Semyung University, KR

We investigated the dynamic properties of graphene-nanoribbon (GNR) memory encapsulating graphene-nanoflake (GNF) shuttle in the potential to be applicable as a non-volatile random access memory via molecular dynamics simulations. This work explicitly demonstrates that the [...]

Different contribution of carbon nanotubes and graphene oxide in single nucleotide polymorphism for the diagnosis of human mad-cow disease

Choi W., Lee J-H., Luminescent MD, LLC, US

Rapid single nucleotide polymorphism (SNP) with 1,1’-oxalylimidazole chemiluminescence (ODI-CL) detection was developed for the early diagnosis of human mad-cow disease. Mutated single strand DNA (ssDNA) sequence discovered from patients having human mad-cow disease rapidly hybridize [...]

Combination of magnetic and non-magnetic graphene oxide to develop chemiluminescent aptasensor capable of rapidly quantifying tumor markers

Choi H-K, Park L., Kim J., Lee J-H., Luminescent MD, LLC, US

Rapid and sensitive chemiluminescent aptasensor capable of rapidly sensing tumor markers in human serum with the combination of magnetic and non-magnetic graphene oxide. Human serum (150 µl) containing tumor markers (e.g., AFP and PSA) was [...]

Background free biosensor using the combination of graphene oxide and Fe3O4 nanoparticles

Cho S., Park L., Chung R., Lee J-H., Luminescent MD, LLC, US

Cost-effective and rapid biosensor with background free chemiluminescence (CL) detection was developed using ssDNA aptamer-conjugated 6-FAM fluorescein (DAF), graphene oxide bound with magnetic nanoparticle (GMN), and 3,4,5-trimethoxyphenylglyoxal (TMPG). When thrombin was incubated in TE buffer [...]

Development of rapid aptasensor using graphene oxide and 1,1’-oxalyldiimidazole chemiluminescence detection

Kwun J., Yun S., Lee J-H., Luminescent MD, LLC, US

Highly selective and sensitive aptasensor capable of rapidly quantifying Vibrio parahaemolyticus in the presence of Vibio cholera and Vibrio vulnificus was developed using an specific DNA aptamer, graphene oxide and 1,1’-oxalyldiimidazole chemiluminescence (ODI CL) detection. [...]

Investigation of optimal separation condition in negative dielectrophoresis force based particle sorting platform

Lee J-H., Kim B-K., Kim Y.H., Kim B-K., Kim Y.H., Kim B-K., Kim Y.H., Korea Aerospace University, KR

we investigate an optimal separation condition regarding the gravitation, the hydrodynamic force and the n-DEP force acting on particles in the sorting platform since contribution of each force is the main parameter to determine SE. [...]

Surface Plasmon Grating Coupled Emission from Organic Emitter for Detecting Refractive Index Variation

Chiu N.-F., Lee J-H., Lin C-W, National Taiwan Normal University, TW

We demonstrated the surface plasmon grating coupled emission (SPGCE) from photo-excited organic layer covered with metal thin film on the corrugated substrate. Directional emissions corresponded to the resonant condition of surface plasmon modes on the [...]

Charge Confinement in Silicon Nanowires by Surface Functionalization

Shih Y.-C., Lee J-H., Lin C-T, Chen C-S, Wu K.-C., National Center for High-performance Computing, TW

Silicon nanowires (SiNWs) are expected to play an important role in nanotechnology because they possess remarkable physical property and compatibility with current Si-based fabrication. They have been successfully used in advance applications such as biosensors, [...]

Propagation and Emissions of Ammonia-substituted Hydrogen/Air Flames

Lee J-H., Lee S.I., Lee J-H., Lee S.I., Kwon O.C., Sungkyunkwan University, KR

In order to evaluate the potential of partial ammonia (NH3) substitution to improve the safety of hydrogen (H2) use in general and the performance of internal combustion engines in particular, the propagation, development of surface [...]

A Molecular Dynamics Modeling on Cantilevered Triple-Walled Carbon Nanotube Resonators

Lee J-H., Kwon O-K., Kang J-W, Hwang H-J., Sangmyung University, KR

We introduce intertube interactions of cantilevered (3,3)(8,8)(13,13) triple-walled carbon nanotube resonators via classical molecular dynamics simulations. The fundamental frequencies of TWCNT resonators were less than those of single- and double-walled carbon nanotubes of a given [...]
