Active Air Bearing Technology for Compensating Multi-DOF Motion Errors of Ultra-Precision Motion Units

Ro S.-K., Khim G., Park J.K., Korea Institute of Machinery and Materials, KR

In this paper, we introduce rotary and linear motion units with active magnetic preloads and show experimental results for active compensation of motion errors by feedforward method. To compensate motion errors, linear stage and rotary [...]

Hydrothermal approach to a carbon graphite encapsulated FeCo nanocrystals for diagnosis, hyperthermia therapy and siRNA delivery

Park J.K., Jung J.J., Subramaniam P., Shah B., Kim C.J., Lee J-K, Lee K.B., Lee J-K, Lee K.B., Korea Research Institute of Chemical Technology, KR

An effective therapeutic approach against cancer requires the combination of several modalities such as chemotherapy, radiation, and hyperthermia. However, the development of multifunctional nanomaterial-based systems that can provide the combined therapeutics and molecular imaging with [...]

Europium-doped gadolinium sulfide nanoparticles as a multimodal imaging agents for bio-application

Park J.K., Lee S.J., Korea Research Institute of Chemical Technology, KR

Most of the magnetic nanoparticles based on iron oxides have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging (MRI) contrast enhancement, tissue repair, hyperthermia, medical diagnostics, and therapeutics. These [...]
