  • Publication number: 20170268964
    Abstract: The present invention relates to an aerosol sampling system operating at a high temperature and pressure, and in particular to a system which is able to sample and analyze an aerosol. The present invention aims to provide a system which is able to carry out measurements, for example, a sampling, an analysis, etc. at a high temperature and pressure, which was unavailable in the past since there is not any aerosol measuring system to sample and analyze at a high temperature and pressure.

  • Publication number: 20110094588
    Abstract: This disclosure relates to novel organic dye and a method for preparing the same. The dye compound of the present invention, when used for a dye-sensitized solar cell (DSSC), shows improved molar absorption coefficient, Jsc (short circuit photocurrent density) and photoelectric transformation efficiency, compared to dyes of the prior art, thus largely improving solar cell efficiency, and it may be purified without expensive column thus remarkably lowering dye synthesis cost.
