Small Angle Neutron Scattering Study of Nano Sized Precipitates in Ferrous Alloys.

Nano-sized precipitates in a Fe-1 wt% Cu alloy were studied by SANS (Small Angle Neutron Scattering). The SANS experiments were performed with the 40 m SANS instrument at HANARO. Due to the ferromagnetic nature of the ferrous alloys, a horizontal magnetic field of 1 Tesla was applied during the SANS experiment.

Detection of gamma-irradiation effect on DNA and protein using magnetic sensor and cyclic voltammetry.

In this study, a magnetic sensor utilizing Planar Hall Resistance (PHR) and cyclic Voltammetry (CV) for detecting the radiation effect was fabricated. Specifically, we applied in parallel a PHR sensor and CV device to monitor the irradiation effect on DNA and protein respectively. Through parallel measurements, we demonstrated that the PHR sensor and CV are sensitive enough to measure irradiation effect.

Development of flexible self adhesive patch for professional heat stress monitoring service.

Too much exposure in a very hot environment can cause heat stress which leads to the fatal heat stroke. To prevent heat stress related diseases, flexible self adhesive patch for professional heat stress monitoring service has been developed. By using flexible printed circuit board (PCB) and silicone based packaging, high level of robustness and ease of usage has been accomplished.
