  • Patent number: 10889537
    Abstract: The present invention relates to a method for producing fluorine-containing dialkyl carbonate compounds, which are suitable as non-aqueous solvents for non-aqueous electrolytes used in secondary batteries. When an alkyl chloroformate and an alcohol are reacted in the presence of an ether-containing imidazole derivative base, the reaction can be carried out at room temperature as compared with the prior art, and the products can be separated within a short time from the reactants. This is an economical process, and according to the present invention, it is possible to obtain alkyl carbonates containing fluorine atoms simply and without difficulty in the removal of solvents, salts formed during the reaction, and by-products.

  • Publication number: 20200407713
    Abstract: The present invention relates to a transformed human cell and a use thereof and, more particularly, to a cell transformed with a gene for coding an MHC I cell membrane receptor and an MHC II cell membrane receptor by using a gene expression suppressing system using a guide RNA, and a use thereof. Such a transformed cell can effectively exhibit the therapeutic effect of cells even in vivo, and cannot be removed by an in vivo immune response. Therefore, it is expected that a composition comprising the immunocyte as an active ingredient can be usefully used for the treatment of cancer, infectious diseases, degenerative diseases or immunological diseases.

  • Publication number: 20200352460
    Abstract: A pixel circuit includes a sensing block, a stimulation block, a first line control circuit, and a second line control circuit. The sensing block outputs biometric data of a biosignal in response to a first selection signal. The stimulation block radiates a stimulation signal in response to a second selection signal. The first line control circuit outputs the first selection signal for selecting the sensing block as a target sensing block, and outputs the second selection signal for selecting the stimulation block as a target stimulation block. The second line control circuit processes characteristic data associated with the biometric data and the stimulation signal.
