摘要： A method for manufacturing a multilayer ceramic electronic component includes preparing a ceramic green sheet, forming a plurality of internal electrode patterns on a main surface of the ceramic green sheet, applying a ceramic paste above the main surface of the ceramic green sheet, stacking a plurality of the ceramic green sheets, pressing the plurality of stacked ceramic green sheets, and cutting the plurality of pressed ceramic green sheets. The ceramic paste at least partially overlaps end portions of the internal electrode patterns, and a stepped region is provided on the ceramic green sheet. When cutting the ceramic green sheets in a first direction, the cutting is performed at a position of the stepped region between two of the internal electrode patterns adjacent to each other in a second direction.

摘要： The disclosure provides a chemical reduction of a metal in a cable of an electrical network, which brings about an improvement in the conductive properties of said metal and a reduction in losses during electric power transmission. The invention discloses a reducing compound with a high concentration of quasi-free electrons, which is obtained as a result of the solvation of metals selected from group I and group II of the main group of the periodic table of elements and of amines selected from the group consisting of: pyridine, and dimethylformamide dispersed in a liquid oligomer, with a metal:amine:dielectric molar ratio of 1:2:1.5, allowing, in an alternating electromagnetic field, to initiate a pulsed injection of electrons into the network with a periodicity equal to frequency of alternation of the voltage.

摘要： A method for preparing a supercapacitor with good cycling stability uses NiO@CoMoO4/NF, an activated carbon plate, a KOH solution (6 mol/L), and polypropylene as raw materials, and is implemented through preparation of an NiO@CoMoO4/NF electrode and assembly of the supercapacitor, wherein the NiO@CoMoO4/NF is the anode of the supercapacitor, the activated carbon plate is the cathode of the supercapacitor, the KOH solution is the electrolyte, and the polypropylene is an isolation plate. The NiO@CoMoO4/NF electrode in the supercapacitor of the present disclosure treated with the ductile material can better adapt to volume changes during the charging and discharging process. After 10,000 cycles of charging and discharging, the capacity of the present disclosure has not faded and still maintains 100% of the maximum capacity, with a high specific capacitance of 79.4 F/g, an energy density of 35.7 Wh/kg, and a functional density of 899.5 W/kg.
