Disclosed is a bus stop using a large-scale perovskite solar cell in which a perovskite solar cell is prepared using a hybrid structure including a graphene-carbon nanotube. The bus stop includes a body unit fixed to the ground to maintain the overall shape, a solar cell unit for producing electrical energy from sunlight, and an energy storage system (ESS) for storing the electrical energy produced by the solar cell part.

The present disclosure relates to a method for producing a coating film having high heat resistance, high hardness and wear resistance, a coating film having high heat-resistance, high hardness and wear resistance produced using the method, and a cutting tool including the same. The method includes forming a metal nitride layer on a metal base; forming a carbon layer on the metal nitride layer; and irradiating a laser into the carbon layer to add carbons into a portion of the metal nitride layer, thereby to form a carburized layer.

Disclosed herein are a method for synthesizing one-dimensional helical mesoporous structure, in which a self-assembled structure of a glycine-derived surfactant is used as a template at room temperature to synthesize the one-dimensional helical mesoporous silica structures having a uniform pore size and a method for synthesizing a glycine-derived surfactant for synthesizing the helical nanoporous structures, in which relatively expensive surfactant can be easily recovered using an organic solvent and reused, which provides economical and environment friendly effects and the glycine-derived surfactant is synthesized by homogeneously heating a reaction product of glycine and phthalic anhydride by dielectric heating with irradiation of microwave, whereby it is possible to realize high yield of the glycine-derived surfactant, shortened synthesis time and increase in energy efficiency, leading to improvement in productivity and reduction in production cost.
