摘要:
The present invention relates to a method for preparing a T-20 peptide by the high-cell-density cultivation of recombinant E. coli containing a T-20 peptide-coding gene, as well as a method for isolating and purifying the T-20 peptide with high purity from E. coli where the T-20 peptide have been expressed. According to the present invention, the recombinant E. coli containing the T-20 peptide-coding gene can be cultured at a high cell concentration, and the T-20 peptide can be isolated and purified with high purity from said recombinant E. coli, thereby making it possible to obtain the inventive T-20 peptide with high industrial value economically.

An organic solar cell and a method of manufacturing the same. This invention relates to a method of manufacturing an organic solar cell including forming nano patterns on a photoactive layer using a nanoimprinting process, and applying a cathode electrode material on the photoactive layer having the nano patterns so that the cathode electrode material infiltrates the nano patterns of the photoactive layer, thus increasing electron conductivity and efficiently forming a pathway for the transfer of electrons, and to an organic solar cell manufactured through the method. This method reduces loss of photocurrent occurring as a result of aggregation of an electron acceptor material and improves molecular orientation of an electron donor in the nanoimprinting process to thus increase cell efficiency. Thereby, the organic solar cell having high efficiency is manufactured at low cost through a simple manufacturing process. The method can be applied to the fabrication of organic solar cells which use an environmentally friendly and recyclable energy source.

A wall-mounted microwave oven in which a bottom plate adapted to be mounted to a lower end of an oven body is easily detachable. The wall-mounted microwave oven includes a coupling unit for mounting the bottom plate to the lower end of the oven body. The coupling unit includes a plurality of engagement slots formed through the lower end of the oven body at positions spaced apart from one another, respectively, and a plurality of engagement hooks provided on the bottom plate at positions corresponding to the positions of the engagement slots, and adapted to be engaged with the engagement slots in a state of being inserted into the engagement slots, respectively. Since the mounting of the bottom plate to the oven body is achieved by engagement between the engagement hooks and the engagement slots, it is possible to mount and separate the bottom plate easily.

Disclosed is a case structure for housing a fishing hook capable of holding a fishing hook in safe and being attached to a fishing rod case without movement. The case structure for housing the fishing hook includes: a case body having a fishing hook receiving part with a predetermined area for receiving and holding a fishing hook and a cover part coupled to the fishing hook receiving part to be opened and closed; and a projection formed on the fishing hook receiving part in such a manner as to be projected by a predetermined height from the top surface of the fishing hook receiving part for catching the fishing hook. The case body has an elastic fishing string mounted at one side of the case body and having a fixing ring, so that the fishing hook case can be attached to the fishing rod case without movement.
