  • Non-destructive method for measuring thickness of three-layered reinforced hydrogen ion exchange membrane for fuel cell
    Patent number: 11913773
    Abstract: The present invention relates to a method of non-destructively measuring a thickness of a reinforcement membrane, and more particularly, to a method of non-destructively measuring a thickness of a hydrogen ion exchange reinforcement membrane for a fuel cell, in which the reinforcement membrane has a symmetric three-layer structure including a reinforcement base layer and pure water layers disposed at opposing sides of the reinforcement base layer, including performing total non-destructive inspection and omitting a process of analyzing a position by means of a thickness peak of a power spectrum of the respective layers of the reinforcement membrane.

  • Hyperthermophilic DNA polymerase and methods of preparation thereof
    Patent number: 8257953
    Abstract: The present invention relates to a hyperthermophilic DNA polymerase and a preparation method thereof. The invention provides a novel hyperthermophilic DNA polymerase isolated from a Thermococcus sp. strain, a functional equivalent thereof, a protein having the amino acid sequence thereof, and a preparation method thereof. The DNA polymerase according to the invention is a DNA polymerase, which is hyperthermophilic and has an elongation ability and fidelity higher than those of prior commercial DNA polymerases. Thus, the DNA polymerase according to the invention will be useful in precision analysis, precision diagnosis, identification and the like, which require accurate PCR.
