  • Patent number: 11519148
    Abstract: A water-oil separation device uses a difference in density between water and oil. The water-oil separation device can easily and quickly separate oil by using a polymer film floating at interface between water and oil. The water-oil separation device easily and quickly collects oil of various viscosities with a simple structure by using differences in density between materials without using a conventional lyophilic/lyophobic film, thus solving the drawbacks of conventional filter-based and adsorption-based methods, and enabling quick and effective responses to actual oil spill situations.

  • Publication number: 20220249482
    Abstract: The present invention relates to a N2,N4-diphenylpyrimidin-2,4-diamine derivative, a method for preparing the same, and a pharmaceutical composition for the prevention or treatment of cancer, containing the same as an active ingredient. The derivative shows a relatively weak EGFR activity inhibitory effect on wild-type EGFR, a high inhibitory ability on EGFR mutation, and a high inhibitory ability on even FLT3 and FLT3 mutation, and thus, can be effectively used for the treatment of cancer with EGFR mutation or cancer with FLT3 or a mutation thereof, and the derivative shows a synergy effect at the time of combination administration, and thus can be effectively used for the treatment of combination administration.
