Title: Manufacturing method of interconnected graphitic carbon nanocubes containing nickel and nitrogen and use thereof
Inventor: PARK JAEHUI
IPC: H01M10/052
Filed: 2021-07-15
Abstract: The present invention relates to a method for synthesizing interconnected one-dimensional graphite nanocubes containing nickel and nitrogen and to application thereof as a functional separator for a lithium-sulfur battery and an electromagnetic wave shielding material. The structure of interconnected one-dimensional graphite nanocubes containing nickel and nitrogen induces internal reflection of EM waves and provides meso- and macro-porous spaces that can confine the active materials of lithium-sulfur cells. Nickel nanoparticles partially embedded inside graphite nanocubes act as self-absorbers and electrocatalysts for EM and EC barriers, respectively. Nitrogen atoms doped into the highly crystalline graphite wall not only improve the electrical conductivity against the conduction loss of EM waves but also enhance the chemical interaction with the active materials. Various electromagnetic and electrochemical analyses show that graphite nanocubes have excellent performance as EM and EC barriers. As a result, the electromagnetic wave shielding material based on graphite nanocubes, which is an EM barrier, shows an optimal RL value of -62.1 dB at 12.1 GHz with a small amount of graphite nanocubes. Additionally, a resulting lithium-sulfur battery using a graphite nanocube-based functional separator as an EC barrier shows excellent rate performance and stable cycling performance at high rates. The interconnected graphite nanocubes containing nickel and nitrogen according to the present invention have the effect of providing a wide range of alternatives for designing new carbon nanomaterials with unique microstructures and diverse functions.

Title: Connecting device for PHC pile
Inventor: PAIK KI WON
IPC: E02D5/52
Filed: 2021-07-20
Abstract: The present invention relates to a connecting device for a PHC pile. A shear fixing key is inserted into keyholes formed only in support surfaces of upper and lower protrusion plates having both support surfaces inclined at an angle in one direction from a vertical direction, so that an upper PHC pile and a lower PHC pile can be easily coupled. After the upper and lower PHC piles are coupled, if a tensile force is applied to a joint portion, the separation and rotation of the upper and lower protrusion plates are suppressed by the shear fixing key inserted into the support surfaces. The other support surfaces of the lower protrusion plates hold those of the upper protrusion plates that will move upward, and thus the separation thereof is suppressed. Therefore, a stable connection state therebetween can be maintained. The key holes are formed only in the support surfaces of the upper and lower protrusion plates to use only 1/2 of the shear fixing key, thus reducing material and construction costs and shortening construction time, thereby ensuring economic feasibility.
