Abstract: The present disclosure relates to humidity sensitive nano-photonics and a manufacturing method thereof, and more particularly to humidity sensitive nano-photonics including a metasurface and a method for manufacturing the same. The humidity sensitive nano-photonics and the manufacturing method thereof according to an embodiment of the present disclosure include a metasurface that are capable of expanding and contracting depending on changes in the relative humidity of the surrounding environment, and have the advantage of being easily manufactured, mass-produced at low cost, capable of effectively adjusting the phase and intensity of light, and applicable to various materials and various shapes of surfaces as well.

Abstract: A secondary battery includes: a can having an accommodation space therein; an electrode assembly accommodated in the accommodation space in the can; and a cap assembly sealed with the can. The can has a beading part recessed into a side wall of the can at a region below where the cap assembly is accommodated, and the beading part has an acute angle with respect to the side wall of the can.

Abstract: According to an embodiment of the present invention, there is provided method for preparing low-loss hydrogenated amorphous silicon nitride that is transparent in visible light comprising: a step in which a substrate is provided; a step in which a Plasma Enhanced Chemical Vapor Deposition (PECVD) which is used to insert H2 gas and SiH4 gas into a chamber is used to deposit a dielectric layer 200 onto the substrate, and gases inserted into the chamber further comprise N2 gas apart from the H2 gas and the SiH4 gas. Further, there is provided a method for preparing low-loss hydrogenated amorphous silicon oxide that is transparent in visible light further comprising O2 gas apart from the H2 gas and the SiH4 gas. Further, there is provided a method for preparing low-loss hydrogenated amorphous silicon that is transparent in visible light further comprising Ar gas apart from the H2 gas and the SiH4 gas.

Abstract: A method and apparatus for hygienically preparing dried peppers by continuously sterilizing and drying fresh peppers are provided. The method includes: screening fresh peppers, removing the stems of the peppers, and aging the peppers; washing the peppers to remove foreign materials and pesticide residue from the surfaces of the peppers; optionally sterilizing the surfaces of the washed peppers using a chemical sterilant solution; cutting and separating seeds from the washed or sterilized peppers; sterilizing the cut peppers using a chemical sterilant solution and/or high-temperature and high-pressure steam; drying the sterilized peppers by hot air or freeze-drying; and grinding the dried peppers into a product. The preparation method includes repeated sterilization and drying processes so that a sanitary problem common to dried peppers can be solved.
