Abstract: An optical fiber flexible multi-wavelength filter based on a polarization-diversity loop includes a pair of high-birefringence optical fibers, a polarization beam splitter connected to the pair of high-birefringence optical fibers and dividing light incident from a broadband light source into two polarized beams, and a polarization controller connected to the high-birefringence optical fibers or the polarization beam splitter and controlling the two polarized beams divided by the polarization beam splitter. The polarization controller includes a ½ wave plate or a ¼ wave plate, and the polarization controller disposed between the high-birefringence optical fibers controls an angle difference between principal axes of the high-birefringence optical fibers and visibility. Interference in the high-birefringence optical fibers is controlled via changing polarized light incident from the broadband light source using the polarization controller.

Abstract: A polymer solar cell including a cathode buffer layer (CBL) is proposed. the CBL may include a reaction product between a conjugate polymer electrolyte and an acid derivative, the conjugate polymer electrolyte is poly [(9,9-bis 3′-(N,N-dimethylamino) propyl)-2,7-fluorene)-alt-2,7-(9,9-dihexylfluorene)] (PFN), and the acid derivative is trifluoroacetic acid (CF3AA), 4-trifluoromethyl benzoic acid (CF3BA), or 4-toluene sulfonic acid (TsOH). The CBL including the conjugate polymer electrolyte (PFN) modified with a specific acid derivative may improve short-circuit current (Jsc) and a filling factor (FF) simultaneously, and thus, significantly improved efficiency is exhibited.

Abstract: An object of the present disclosure is to provide a composition for preventing or treating obesity comprising a substance isolated from poly-γ-glutamic acid (γ-PGA) as an active ingredient. According to the present disclosure, it was confirmed that γ-PGAbm or γ-PGAcm, a substance isolated from γ-PGA, suppressed the expression of adipogenic marker genes in 3T3-L1 cells to reduce accumulation of lipid droplets and triglycerides, and suppressed the expression of cell cycle regulators in the early stage of adipogenesis to reduce adipocyte differentiation. In addition, γ-PGAbm or γ-PGAcm has been confirmed to suppress obesity through weight loss, positive changes in glucose and insulin resistance, reduction of epididymal adipocytes, and suppression of adipogenesis, and thus may be used effectively for related businesses.

Abstract: There are provided a porous composite membrane formed by blending perfluoroalkoxy alkane (PFA) with an organic substance, and a manufacturing method thereof. The porous composite membrane is able to have pores easily formed simply by blending a fluorine-based polymer with an organic substance without additional pore-forming processes such as stretching and heating, and exhibit excellent properties in terms of resistance to high temperatures and strong acids due to the use of the fluorine-based polymer as a base material, so it is available for use in semiconductor wastewater treatment that uses strong acids like HF.
