20120010697 | HEART VALVE PROSTHESIS USING DIFFERENT TYPES OF LIVING TISSUE AND METHOD OF FABRICATING THE SAME - A heart valve prosthesis and a method of fabricating the same. The heart valve prosthesis uses a leaflet of pig pericardium or a leaflet of cattle pericardium, which has a suitable thickness according to the size of the valve, and a stent. The heart valve prosthesis is fabricated by placing a valve body over a Dacron body, binding the valve body to the Dacron body using stitching fiber, rolling the Dacron body into a cylindrical form such that the valve body is located inside, binding opposite edges of the Dacron body to each other using stitching fiber, and inserting the resultant structure into a stent, which is knitted using a shape memory alloy wire. The heart valve prosthesis is friendly to and is not rejected by human tissue, is free from deformation, and can be implanted using a non-invasive manner without incising the chest wall of a patient. | 01-12-2012 |
20130284639 | HYDROCRACKING PROCESS OF HEAVY HYDROCARBON DISTILLATES USING SUPERCRITICAL SOLVENT - Specific embodiments of the present invention provide a hydrocracking process for converting low value-added heavy hydrocarbon distillates into high value-added hydrocarbon distillates using a supercritical solvent as a medium. | 10-31-2013 |
20140377814 | Method For The Fixation Or Conversion Of High-Pressure Carbon Dioxide Using Barophilic Sulfur-Oxidizing Chemolithoautotrophs - The present invention relates to a method for biologically treating carbon dioxide using the sulfur-oxidizing chemolithoautotroph | 12-25-2014 |
20150218459 | Simultaneous Pretreatment Method Of Heavy Hydrocarbon Distillate And Lignocellulosic Biomass Using Solvent - A method of reforming a heavy hydrocarbon distillate, which includes treating a heavy hydrocarbon distillate and a lignocellulosic biomass with a solvent, is provided. | 08-06-2015 |
20150283535 | METHOD FOR PREPARING HOLLOW CARBON STRUCTURE USING CRACKING REACTION OF HEAVY HYDROCARBON FRACTION - The present invention relates to a method of preparing a hollow carbon structure. The method includes a step of calcining a solid component separated after a cracking reaction of a heavy hydrocarbon fraction; and a step of performing an acid treatment or base treatment on the solid component calcined in the above-described step. | 10-08-2015 |
20150293106 | DIAROMATIC AMINO ACID SUBSTRATE FOR CATHEPSIN DETECTION - The present invention relates to a diaromatic amino acid substrate for cathepsin detection. When the substrate used for cathepsin detection is a polymer resulting from the binding of a protease-preferred amino acid and quencher to a diaromatic amino acid, cathepsin can be detected sensitively and accurately by fluorescence because cathepsin causes the protease-preferred amino acid and quencher to dissociate from the diaromatic amino acid, and fluorescence is recovered during this time. | 10-15-2015 |
20150360199 | PROCESS FOR PREPARING CARBON DIOXIDE ADSORBENT AND CARBON DIOXIDE CAPTURE MODULE CONTAINING THE ADSORBENT - The present invention relates to a method of preparing a carbon dioxide adsorbent and a carbon dioxide capture module including the adsorbent prepared thereby. | 12-17-2015 |
