Patent number: 11634364Abstract: The present disclosure provides a boron carbide composite material having a novel composition with excellent mechanical properties, and a production method therefor. The boron carbide composite material has high fracture toughness and may be applied as a lightweight bulletproof ceramic material. The boron carbide composite material is a boron carbide/silicon carbide/titanium boride/graphite (B4C—SiC—TiB2—C) composite material. The composite material may overcome a technical limitation on increasing the fracture toughness of the boron carbide composite material, and may be produced as a high-density boron carbide composite material using a reactive hot-pressing sintering process at a relatively low temperature.Type: GrantFiled: February 24, 2021Date of Patent: April 25, 2023Assignee: Korea Institute of Science and TechnoloyInventors: Sang Whan Park, Mi Rae Youm, Sung Il Yun, Jun Hyung Park

Publication number: 20230123164Abstract: The present invention relates to a composition using a urine sample for diagnosis of a kidney disease and, more specifically, to a urine test composition and a kit for diagnosis of a kidney disease, each comprising an agent specifically detecting amphiregulin from a urine sample, and a method for diagnosing a kidney disease by using the composition. According to the present invention, not only is there an advantage of being able to conveniently diagnose a kidney disease in a non-invasive manner using a urine sample for a kidney disease to which early diagnosis is important, but also the application of the present invention to a patient diagnosed with chronic kidney disease can advantageously predict the plausibility of progression into end-stage renal disease in advance.Type: ApplicationFiled: April 12, 2021Publication date: April 20, 2023Inventors: Seung Seob SON, Tae Rim KIM, Eun Young LEE, Nam-Jun CHO, Sung Il YUN, Jun Hong PARK, Han-Oh PARK

Patent number: 10688478Abstract: The present invention relates to a method for preparing a metal catalyst (Ni, Co, etc.)-supported porous silicon carbide structure having meso- to macro-sized pores, high porosity and superior mechanical properties. Unlike the existing method wherein a porous silicon carbide structure is prepared and then the metal catalyst is infiltrated therein, the preparation of the porous silicon carbide structure and the supporting of the metal catalyst occur at the same time by the mixing metal catalyst material and starting materials. As a result, the metal catalyst is distributed uniformly in the porous silicon carbide structure and it is possible to locate a desired amount of the metal catalyst inside the porous silicon carbide structure.Type: GrantFiled: October 24, 2018Date of Patent: June 23, 2020Assignee: Korea Institute of Science and TechnologyInventors: Sang Whan Park, Mi Rae Youm, Sung Il Yun
