Abstract: The present disclosure provides a Cu1.81S catalyst for synthesizing NH3 and a method for synthesizing NH3 using the same. According to the present disclosure, the Cu1.81S catalyst is provided in order to increase an efficiency of NH3 synthesis. A copper sulfide catalyst and the method for synthesizing NH3 via an electrochemical nitrogen reduction reaction (NRR) using the Cu1.81S catalyst are provided in order to reduce a limiting potential (UL) required for the NRR. In the NRR for the NH3 synthesis, it is provided the copper sulfide catalyst that can be used in any one of two different pathways for the NRR, and the method for synthesizing NH3 with higher activity of the NRR based thereon.

Abstract: Disclosed is an entropy-controlled solid solution matrix BCC alloy having strong resistance to high-temperature neutron radiation damage. The entropy-controlled solid solution matrix BCC alloy includes three or more multicomponent main elements selected from the element group consisting of Zr, Al, Nb, Mo, Cr, V, and Ti selected based on a neutron absorption cross-sectional area and a mixing enthalpy. Each of the elements is included in an amount of 5 to 35 at %, and the entropy-controlled solid solution matrix BCC alloy is a BCC-structure solid solution matrix alloy in a medium-entropy to high-entropy state. In this invention, damage caused by neutron radiation is reduced, and entropy is controlled to thus ensure a solid solution matrix BCC structure having a slow diffusion speed, and accordingly, resistance to void swelling due to radioactive rays is high.

Abstract: A membrane device includes a trench substrate having trenches and a membrane having wrinkles. The membrane is not bonded to the trenches of the trench substrate but is bonded to the surface of the trench substrate in the shoulders of the trenches. Hills and valleys are alternately arranged in the membrane along the trenches. The membrane device can be used in various applications (for example, sensors) based on variations in the electrical properties of the membrane caused by a change in the shape of the wrinkles (a change in the strain) of the membrane in response to a change in the internal or external environment of the trenches.

Abstract: Disclosed are a method for manufacturing a high-density neural probe including needles having various forms and a neural probe manufactured thereby. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.

Abstract: A transparent planar heating film includes metal nanoparticles that are disposed on at least a portion of a transparent adhesive film; and a transparent electrode that is completely covered by the transparent adhesive film and has a conductive surface that is laminated to and in direct contact with the metal nanoparticles via the transparent adhesive film. The heating temperature of the transparent planar heating film is a maximum of at least two times higher at the same power consumption than that of conventional planar heating films. Both the transparent adhesive film and the transparent electrode may be flexible so that the transparent planar heating film is flexible. In the transparent planar heating film, the metal nanoparticles may be bonded to desired locations on the conductive surface of the transparent electrode enabling selective heating.
