Abstract: An exemplary embodiment of the present disclosure provides a physically unclonable function (PUF) cell capable of exhibiting a stable performance and showing an excellent repeatability while being less affected by environmental factors such as a noise, temperature, and bias voltage. The PUF cell generates an output value by combining a scheme of amplifying a threshold voltage difference and a scheme of amplifying an oscillation frequency difference. In an oscillator that generates oscillation signals of different frequencies, the frequency difference of the oscillation signals is amplified by alternately supplying bias voltages of different magnitudes generated by utilizing the threshold voltage difference to a plurality of stages in the oscillator.

Abstract: The present disclosure relates to a transition metal-doped nickel phosphide nanostructure, a method for preparing the same, and a catalyst for electrochemical water decomposition including the transition metal-doped nickel phosphide nanostructure. More specifically, a transition metal-doped nickel phosphide nanostructure can be prepared by converting a zinc oxide nanostructure grown on a substrate vertically by hydrothermal synthesis to a transition metal-doped nickel oxide nanostructure by cation exchange and then phosphorizing the nickel oxide. The transition metal-doped nickel phosphide nanostructure of the present disclosure is advantageous in that it has superior catalytic activity and conductivity due to large surface area. In addition, when used as a catalyst for water decomposition under an alkaline condition, it has a low overvoltage and can have excellent catalytic activity for hydrogen evolution reaction or oxygen evolution reaction.

Abstract: The present invention relates to a contact lens for diagnosis and treatment of dry eye syndrome. The contact lens, according to the present invention, may diagnose dry eye syndrome by means of a change in an electric current occurring as a result of a field effect when a dry eye syndrome biomarker binds to a probe, and when dry eye syndrome is diagnosed, generates an electric current so that a gold film blocking a drug reservoir melts by the electric current, thereby enabling the release of a drug to be controlled.
