Abstract:
유수분리 구조체 및 그 제조방법, 상기 유수분리 구조체를 포함하는 유수분리 장치, 및 상기 유수분리 장치를 이용한 유수분리방법이 제공된다. 상기 유수분리 구조체는 적어도 일 표면에 나노 패턴을 형성하는 복수개의 돌출부를 포함하는 다공성 기재; 및 상기 돌출부 중 적어도 일부의 단부에 배치된 무기 입자;를 포함한다. 상기 유수분리 구조체는 친수성 내지 초친수성 표면 특성을 가짐으로써, 물과 기름 중 물은 선택적으로 통과시키고, 기름을 용이하게 분리하여 수거해 낼 수 있다. 상기 유수분리 구조체는 제조공정이 친환경적이고, 대면적화가 가능하다. 상기 유수분리 구조체를 포함하는 유수분리 장치는 반복 사용이 가능하여 추가적인 환경오염을 방지할 수 있다.
Abstract:
A micro generator and a manufacturing method thereof are provided to generate bubbles even when a temperature difference between fluid and a heating unit is small, and to control the bubble generating position and height easily. A manufacturing method of a micro generator(20) includes a step of preparing a bottom heating surface(11); a step of coating and soft-baking a photoresist(12) on the bottom heating surface; a step of positioning a mask(13) on the photoresist and exposing the mask to ultraviolet rays; a step of performing post exposure, dipping the photoresist into a developing solution and developing a wall structure of the photoresist and a micro cavity(15); a step of stacking micro particles(17) in the micro cavity; a step of forming side walls on the bottom heating surface and mounting a cantilever beam on one the side walls; and a step of sealing the inside by mounting an upper cover on side walls.
Abstract:
PURPOSE: A novel lactobacillus sp. MT-1077 (KCTC 8903P) and a novel bacteriocin produced therefrom are provided. The bacteriocin has stability against broad range of pH, heat stability and antifungal activity and used as food preservation agent, biological fermentation regulator, and antifungal agent. CONSTITUTION: A lactobacillus MT-1077 is isolated from Kimchi. The method for purifying bacteriocin from lactobacillus MT-1077 comprises the steps of: incubating lactobacillus MT-1077 in MRS broth; precipitating the lactobacillus MT-1077 fermented culture broth by addition of ammonium hydrogen sulfate; passing the protein precipitates through the column packed with carboxymethyl sepharose CL-6B and eluting the adsorbed protein with 0.1M sodium chloride; passing the elutes through the column packed with phenyl sepharose CL-4B and eluting the adsorbed protein with 10% ammonium hydrogen sulfate solution; and purifying the elutes by HPLC
