Abstract: Disclosed are a metal single-atom catalyst and a method for preparing the same. The method uses a minimal amount of chemicals and is thus environmentally friendly compared to conventional chemical and/or physical methods. In addition, the method enables the preparation of a single-atom catalyst in a simple and economical manner without the need for further treatment such as acid treatment or heat treatment. Furthermore, the method is universally applicable to the preparation of single-atom catalysts irrespective of the kinds of metals and supports, unlike conventional methods that suffer from very limited choices of metal materials and supports. Therefore, the method can be widely utilized to prepare various types of metal single-atom catalysts. All metal atoms in the metal single-atom catalyst can participate in catalytic reactions. This optimal atom utilization achieves maximum reactivity per unit mass and can minimize the amount of the metal used, which is very economical.

Abstract: Provided is a high-sensitivity sensor having a conductive thin film containing linearly induced cracks. The high-sensitivity sensor relates to a sensor, obtained by forming linearly induced microcracks on a conductive thin film formed on a support, for measuring external tensile and pressure by measuring a change in the electrical resistance due to modification, short-circuiting, or openings in micro-joining structures formed by the microcracks. The high-sensitivity conductive crack sensor may be applied to high-precision measurements or artificial skins, and may be utilized as a positioning detection sensor by pixelating the sensor. Thus, the high-sensitivity sensor may be effectively used in the fields of precise measurements, bio-measurement devices through human skin, human motion measuring sensors, display panel sensors, etc.
