Development and Performance of Recyclable Composites for Wind Turbine Blades

Ma Y., Kim D., Wu M-S, Bai L., Gao X., Qing B., He J., Lib X., Nutt S.R., Liang B., Adesso Advanced Materials Inc., US

Wind energy has become an increasingly important renewable energy source. In 2015 alone, the U.S. wind industry installed wind turbines generating 8,595 MW, a 77 % increase over 2014 [1], and the market growth is [...]

Analytical system capable of rapidly quantifying food-borne pathogen for food safety and public health

Khang J., Kim D., Chung K.W., Lee J-H., Luminescent MD, LLC, US

Cost-effective and easy-to-use biosensor was developed for the rapid quantification and monitoring of Escherichia (E.) Coli O157:H7 in sample using E. Coli O157:H7 aptamer, graphene oxide (GO)/iron nanocomposites, and guanine chemiluminescence detection. E. Coli O157:H7 [...]

Mechanical fabrication of graphene devices using focused-ion beam: deposition and milling

Lei N., Chen Z., Kim D., Xue W., Xu J., Xue W., Washington State University, US

The inherent difficulties in handling and producing graphene have been a major barrier in developing such devices. Conventional microfabrication methods are mostly based on chemical etching processes, which often involve tedious masking and aligning steps. [...]

Extremely Stretchable Electrode based on Combination of Inkjet-Printed Silver and Conductive Composite for Stretchable Lighting Applications

Kim D., Kim S., Byun J., Chung S., Kim D., Kim S., Hong Y., Seoul National University, KR

We have studied stretchable electrode based on combination of inkjet-printed silver electrode and conductive composite materials for stretchable lighting device applications. Previous stretchable electrodes were mainly realized by either vacuum deposition or inkjet-printing of conductive [...]

Capacitance-based real time monitoring of endocytosis

Lee R.M., Kim D., Kim K-M, Kim K., Kim P., Kim D., Kim K-M, Kim K., Kim P., Kim D., Kim K-M, Kim K., Kim P., Kim D., Kim K-M, Kim K., Kim P., Yun C.O., Shin J.-S., Yoo K.H., Yonsei University, KR

There exist three kinds of endocytosis; receptor mediated endocytosis, pinocytosis and phagocytosis. First, receptor-mediated endocytosis is essential for targeted gene/drug delivery to a specific cell type. Second, pinocytosis is the engulfing and digestion of dissolved [...]

A field-emission X-ray source using an anisotropically focused electron beam

Jung S., Kim D., Seol S.K., Korea Electrotechnology Research Institute, KR

A field-emission X-ray source for dental imaging with an anode voltage of 70 kV and an anode current of more than 1 mA was designed and assembled using an anisotropically focused electron beam. With up [...]

Carbonate ion sensing electrode membrane based on poly(vinyl chloride) and its property characteristics

Kim D., Kim H-C, Kim D., Kim H-C, Byun G., Park S-D., Ree M., POETECH, KR

A series of poly(vinyl chloride) (PVC) membranes containing a carbonate ion sensible ionophore, a lipophilic additive, and a plasticizer in various compositions was prepared and then investigated in detail in the aspects of properties and [...]
