Abstract: A membrane device includes a trench substrate having trenches and a membrane having wrinkles. The membrane is not bonded to the trenches of the trench substrate but is bonded to the surface of the trench substrate in the shoulders of the trenches. Hills and valleys are alternately arranged in the membrane along the trenches. The membrane device can be used in various applications (for example, sensors) based on variations in the electrical properties of the membrane caused by a change in the shape of the wrinkles (a change in the strain) of the membrane in response to a change in the internal or external environment of the trenches.

Abstract: Methods of manufacturing a CIGS thin film for a solar cell are provided. According to the method, a CIGS thin film having an ideal double band gap grade structure with a large particle size may be obtained by heat-treating a solution-treated CIG oxide thin film by a three-step chalcogenization process. Accordingly, performance of the solar cell may be improved.

Abstract: A pharmaceutical composition for preventing or treating arthritis, which comprises synthetic polypeptides; injections for preventing or treating arthritis; and a pharmaceutical composition for inducing differentiation of cartilage cells are described herein. Synthetic polypeptides of the present invention consisting of a polypeptide represented by SEQ ID NO: 1 and a polypeptide represented by SEQ ID NO: 2 have activity for recruiting stem cells to an arthritis region, inhibit apoptosis of cartilage cells, and exhibit anti-inflammatory activity and activity for promoting regeneration of cartilage cells. Thus, unlike a conventional arthritis treatment agent, the synthetic polypeptides can improve cartilage damage, can inhibit degenerative changes per se and can, at the same time, exhibit an effect as a stem cell treatment agent, and thereby can be usefully utilized as an arthritis prevention or treatment agent.

Abstract: Provided are: a dry reforming catalyst, in which a noble metal (M) is doped in a nickel yttria stabilized zirconia complex (Ni/YSZ) and an alloy (M-Ni alloy) of the noble metal (M) and nickel is formed at Ni sites on a surface of the nickel yttria stabilized zircona (YSZ); a method for producing the dry reforming catalyst using the noble metal/glucose; and a method for performing dry reforming using the catalyst. The present invention can exhibit a significantly higher dry reforming activity as compared with Ni/YSZ catalysts. Furthermore, the present invention can have an improved long-term performance by suppressing or preventing the deterioration. Furthermore, the preparing method is useful in performing the alloying of noble metal with Ni at Ni sites on the Ni/YSZ surface and can simplify the preparing process, and thus is suitable in mass production.

Abstract: Disclosed is a self-healing polysilsesquioxane and a hybrid film using the same. Once crosslinked, the polysilsesquioxane copolymer can self-heal within several minutes at 100-120° C. The self-healing polysilsesquioxane copolymer can be prepared into a hybrid material in the form of a film. Because the hybrid film has an excellent ability of self-healing the damage caused by external impact, it is applicable to wide applications such as gas separation membranes, etc., without limitation.
