Abstract: The present disclosure relates to a three-terminal synaptic device for artificial neural network learning, a synaptic array using the same, and a method of operating the same. The three-terminal synaptic device includes a first transistor; an electrochemical memory (ECRAM) connected in parallel to the first transistor; and a second transistor connected in series to the parallel structure. Accordingly, the present disclosure can achieve an accuracy improvement of inference and learning operations in an artificial neural network through parallel operation by configuring a cross-point array based on the synaptic device with the three-terminal structure comprised of the electrochemical memory and two transistors.

Abstract: The present invention relates to a novel probe set for an isothermal one-pot reaction, and uses thereof and, particularly, provides a method for easily, accurately, and quickly diagnosing molecules, in particular, infection diseases, in the field, the method having a form applicable in the field on the basis of a nucleic acid sequence by using a one-pot reaction composition under an isothermal condition. If a molecular diagnostic platform according to the present invention is used, a target sequence can be quickly and accurately detected. Also, elements (reaction buffer, enzyme) needed in a diagnostic process using the present invention are much more simple and convenient than in a conventional antibody-based diagnosis, and, thus, the diagnostic process can be performed by a non-skilled person, and the sensitivity and speed of diagnosis can be increased, as all reactions are unified at a constant temperature without expensive equipment used in general nucleic-acid-based molecular diagnostic technology, and an amplification process is performed automatically during a reaction process.

Abstract: The present invention relates to a Ni—Fe-based catalyst for OER doped with a metal having lower electronegativity than Ni and Fe, and a method for manufacturing the same. More specifically, the present invention offers the advantage of using nickel, a non-noble metal-based active catalyst, which has high economic value without the need for noble metals. The present invention provides a method for manufacturing a Ni—Fe-based catalyst for OER that exhibits excellent activity in oxygen generation reaction by maximizing the surface area compared to existing noble metal-based catalysts, thereby contributing significantly to the cost reduction of hydrogen production.
