LED-to-LED visible light communication (VLC) is a technology that LEDs are used as both transmitters and receivers. In this paper, we studied a micro-LED-to-micro-LED VLC since micro LEDs have faster modulation speed and are used in various applicati

A simple water level measurement method based on wavelength division multiplexing (WDM) is proposed and demonstrated. The measurement principle is based on the change of Fresnel reflection occurring at the end facet of the optical fiber tip (OFT). To

Optical wireless communication (OWC) is one of the promising candidates for beyond fifth-generation communication (B5G). Depending on the type of transmitters, receivers, and information carriers applied in the system, OWC can be categorized into vis

A hydrobiotite (HBT) clay contains more cesium (Cs)-specific adsorption sites than illitic clay, and the capacity of frayed edge sites can increase as the weathering of micaceous minerals proceeds. Thus, Cs can be selectively adsorbed to HBT clay. In

In the case of the contaminated soil from the nuclear sites, higher concentrations are found in smaller particles by analyzing the distributions of radioactivity for the various soil particle sizes. Therefore, the methods to separate the highly conta

The desorption of radioactive cesium (Cs) in soil is influenced by the clay mineral type, adsorption site, and concentration of Cs. In this study, experiments to detect desorption of non-radioactive and radioactive Cs from illite using oxalic acid we
