Effect of elevated hot temperatures on hybrid geopolymer synthesized with coal fly and bottom ashes

Kim H., Park C.W., University of Seoul, KR

Ordinary Portland Cement (OPC) concrete has been most widely used for construction materials although the strength deterioration of OPC concrete in high temperature has been pointed out as its inherent flaw. Considering that fire is [...]

Photosensitive Biosensor Array Chips not having the Addressing Circuit

Ahn C-G, Ah C.S., Ahn C-G, Kim A., Kim T., Park C.W., Yang J.H., Kim A., Kim T., Sung G.Y., Electronics and Telecommunications Research Institute, KR

This paper presents photosensitive biosensor array chips with the simple photodiode array having the optical input signal and the electrical output signal, which detects the photocurrent change caused by a reaction between probe molecules and [...]

Label-Free Protein Nano-Biosensor Using Top-Down Fabrication

Ah C.S., Ahn C-G, Kim A., Yu H.Y., Ahn C-G, Yang J.H., Baek I-B, Park C.W., Jun M.S., Lee S.J., Electronics and Telecommunications Research Institute (ETRI), KR

A nanosensor of n-type Si field-effect transistor (FET) via “top-down method” was employed to monitor PSA with great selectivity and high sensitivity up to 10 pg/mL. When a biomaterial, negatively charged PSA, is introduced through [...]
