| 20100206078 | Method for Predicting Failure of Geotechnical Structures - Provided is a method of predicting failure in geotechnical structures using an AE method instead of a conventional displacement or stress measuring method, which belongs to a field of rock mechanics and geotechnical engineering. The method is a measurement technology for identifying signs of failure in geotechnical structures using Acoustic Emission (AE) signals generated by damage in the geotechnical structure and also providing management standard for failure prediction. | 08-19-2010 |
| 20100048741 | Fabrication Method of CaCO3 Nanoparticles Using Beads Milling - The present invention relates to a method for fabricating calcium carbonate nanoparticles dispersed in water from ground calcium carbonate of micrometer (μm) order using beads milling. More particularly, the present invention relates to a method for fabricating calcium carbonate nanoparticles dispersed in water by which a complex aqueous slurry comprising coarse ground calcium carbonate having an average particle size of several micrometers (μm) and a surfactant is subjected to beads milling, such that grinding and dispersion in water of the ground calcium carbonate occur simultaneously, and the resultant calcium carbonate nanoparticles have an average particle size of 10-100 nm and a unimodal clustering distribution. | 02-25-2010 |
