  • Patent number: 11059262
    Abstract: The present invention relates to a method of preparing an aerogel blanket in which, a surface of a base material for a blanket is activated and roughness and porosity of the surface of the base material for a blanket are increased to increase adhesion performance of a silica aerogel by inducing etching of a surface of a base material for a blanket using an acidic solution, and mechanical flexibility is increased and the generation of dust is minimized by further performing a gel deformation process of introducing cracks into the aerogel, and a low-dust and high-insulation aerogel blanket prepared according to the present invention.

  • Patent number: 11014825
    Abstract: The present invention relates to a method for producing potassium titanate, and the present invention provides a method for producing potassium titanate which uses anatase-phased titanium dioxide to simplify the process by a hydrothermal method, and thus may improve economical efficiency and productivity, and in which the reaction temperature, the reaction time and the molar ratio of a precursor may be controlled to produce a high-purity potassium titanate whisker having a nano size of an uniform shape.

  • Patent number: 7820982
    Abstract: Disclosed is a moon grid for transmission electron microscopy tomography, including a mesh sheet for protecting an upper objects and a support film formed on the mesh sheet and having nanoparticles dispersed throughout, in which the nanoparticles dispersed throughout the support film are used as reference points in the reconstruction of two-dimensional transmission electron microscopy images into a three-dimensional image, thus omitting a process of attaching markers in the course of preparation of a sample and easily forming reference points even on a sample to which it is impossible to attach markers. A method of fabricating such a moon grid is also provided.
