    摘要: A method for laser interference lithography using a diffraction grating includes (a) forming a photoresist layer on a work substrate to which a repeated fine pattern is to be formed; (b) forming a refractive index matching material layer on the photoresist layer; (c) forming on the refractive index matching material layer a diffraction grating layer having a period of diffraction grating within the range from λ/ng to λ/n0 (λ is a wavelength of laser beam, ng is a refractive index of the diffraction grating, and n0 is a refractive index in the air or in vacuum); and (d) exposing the photoresist layer by means of mutual interference of positive and negative diffracted lights with the same absolute value by inputting a laser beam perpendicularly to the diffraction grating layer. This method allows to realize an interference pattern with higher resolution and to use a laser source with lower coherence.

    摘要: The present invention relates to a thermosensitive pluronic derivative hydrogel for tissue regeneration in which a biodegradable polymer is introduced at one end or both ends of a pluronic polymer, a methacryloxyethyl trimellitic acid anhydride is conjugated to the biodegradable polymer, and a physiologically active substance is fixed to the methacryloxyethyl trimellitic acid anhydride, as well as a method for the preparation thereof. The pluronic derivative hydrogel according to the present invention exhibits high biodegradability due to the introduction of a biodegradable polymer while still maintaining the themosensitivity of the pluronic polymer itself and shows good biocompatibility owing to the coupling with a physiologically active substance capable of improving cell adhesion, proliferation and differentiation. Therefore, the pluronic derivative hydrogel according to the present invention can be effectively used in the regeneration of various kinds of tissues and organs.

    摘要: A membrane filtration method and an apparatus for continuously monitoring the state of a membrane during the filtration, particularly for membrane fouling due to cake or gel layers of solutes developed on the surfaces of a filtered membrane, by estimating a membrane potential and a membrane solute rejection while making measurements of a set of physical properties of feed, variations of a streaming potential difference across pores of the membrane, variation in pressure differences between an upstream side and a downstream side of the membrane, and concentration differences between the feed and permeate filtered through the membrane.
