Abstract: Proposed is a peptide for skin anti-aging and anti-wrinkle, comprising a glycine-histidine-lysine tripeptide and polyarginine linked to the carboxy-terminus of the tripeptide, and a composition for skin anti-aging and anti-wrinkle comprising the peptide. The peptide and composition may enter the cytoplasm more rapidly and efficiently than a conventional GHK tripeptide, and may exhibit skin anti-aging and anti-wrinkle effects similar to those of the GHK tripeptide even at a lower concentration than that of the GHK tripeptide.

Abstract: Disclosed are a transparent electrode for a solar cell and a method of manufacturing the same. The transparent electrode for a solar cell has a low Young's modulus, excellent elasticity, self-healing properties, an average visible-light transmittance sufficient to implement bifacial properties, and excellent power conversion efficiency (PCE). In addition, the method of manufacturing the transparent electrode for a solar cell does not require an additional deposition process, so the electrode-manufacturing time can be reduced, and the electrode-manufacturing process can be performed separately from other solar-cell-manufacturing processes, which is advantageous for mass production and large-area application.

Abstract: Disclosed is a chemical container capable of discharging gas generated from a chemical by stably securing a discharge passage of the gas even when the posture or tilt of the chemical container is variously changed, i.e. when the chemical container is turned over or falls sideways, whereby it is possible to prevent an excessive increase in internal pressure of the chemical container due to generation of the gas. The chemical container includes a container body having a storage compartment configured to store a chemical, an exhaust port disposed at one side of the container body, the exhaust port being configured to connect the storage compartment and the outside of the container body to each other in such a manner that fluid movement therebetween is possible, an exhaust tube disposed in the storage compartment so as to be connected to the exhaust port in such a manner that fluid movement therebetween is possible, and an exhaust buoyancy unit.
