본 연구에서는 metal organic frameworks (MOFs)의 한 종류인 MIL-100(Fe)을 이용하여 혼합기질막(mixed matrix membranes, MMMs)을 제조하였다. MIL-100(Fe)의 함량을 고분자 대비 0∼30 wt%까지 변화시키면서 첨가된 MOF의 함량에 따른 기체의 투과 특성을 살펴보았다. H2, CO2, O2, N2, CH4의 기체 투과도는 MIL-100(Fe) 첨가량이 증가함에 따라 투과도가 증가하는 경향을 보여주었으며, 상대적으로 큰 입자크기를 가진 SF6의 투과도는 MIL-100(Fe)의 첨가량이 증가함에 따라 투과도가 감소하였다. 이상 선택도는 N2/SF6의 경우 폴리이미드막 대비 약 40% 증가하였으며, 이를 통해 N2/SF6 분리에 적합한 분리막임을 확인할 수 있었다.

Yeolgujatang is traditional casserole with meat, fish and vegetables in special pot. Name of Yeolgujatang was in 1800s, as yeolgujatang, yeolgujatangbang, yeolguja, in 1900s, Yeolgujatang, royal feast food in Yi Dynasty was yeolgujatang, Meon-sinseolro, tangsinseolro. Yeolgujatang frame has legs and a lid, and a cylinder that can contain charcoal at the center of its rounded pot. with this charcoal, food can be cooked. Its material has changed from brazier to brassware, stainless steel, and silver. Nowdays electric sinseolro was also launched, which uses electric power instead of charcoal. Materials in yeolgujatang are beef, intestines, pork, chicken, pheasant, fish, sea bream, abalone, shrimps, vegetables, mushroom, ddock, guksu, cooked rice, seasening and garnish. Nutrition of Yeolgujatang per capita contains 221.5kal of calory, 17.3g of protein, 16.5g of fat, 6.1g of carbobydrates, 2g of fiber, 57.6mg of calcium, 208mg of phosphorus, 4.3mg of ferrum, 2177μgRE of vitaminA, 1.58mg of vitamin B1, 0.3mg vitamin B2, 6.6mg of vitaminC and 5.26mgNE of niacin. Yeolgujatang is excellent in nutrition, except for calcium and vitaminC.
