According to aspects of the present invention, a peptide with any one sequence of SEQ ID NOS:1 to 3 exhibits high selective binding affinity to a target and the microcapsule has superior physicochemical stability. Therefore, the cosmetic composition containing the microcapsule linked to the peptide manifests high delivery efficiency of an active ingredient included in the capsule to target cells, thereby exhibiting superior skin-condition improvement effects.

Microcapsule including peptide having cell receptor binding affinity and cosmetic composition containing same

The present application relates to a method for producing D-psicose, the method comprising the steps of: putting a composition containing a D-psicose borate complex into a chromatography comprising divalent cations; and separating the composition containing the D-psicose borate complex into a D-psicose-containing fraction (i) and a borate-containing fraction (ii).

Method for producing D-psicose from D-psicose borate complex using chromatography and composition containing D-psicose

The present disclosure relates to a membrane for flue gas separation containing a crosslinked, thermally rearranged poly(benzoxazole-co-imide) copolymer prepared simply by heat-treating a membrane prepared from an o-hydroxypolyimide copolymer having carboxylic acid groups such that thermal crosslinking and thermal rearrangement occur simultaneously or a membrane for flue gas separation containing a crosslinked, thermally rearranged poly(benzoxazole-co-imide) copolymer having a benzoxazole group content of less than 80% in the polymer chain, prepared from transesterification crosslinking of an o-hydroxypolyimide copolymer having carboxylic acid groups and a diol-based compound followed by thermal rearrangement, and a method for preparing the same. In accordance with the present disclosure, a crosslinked, thermally rearranged poly(benzoxazole-co-imide) copolymer membrane for flue gas separation can be prepared simply through heat treatment without requiring a complicated process such as chemical crosslinking, UV irradiation, etc. for forming a crosslinked structure and a membrane for flue gas separation prepared therefrom exhibits superior permeability and selectivity. Also, the method is applicable to commercial-scale production because the preparation process is simple.
