The present invention provides a composite sheet having good formability and stretchability. An electrode according to one embodiment of the present invention is provided with a core material and a composite material sheet bonded to the surface of the core material, the composite material sheet containing a conductive material-coated active material in which a conductive material is adhered to the surface of the active material and a fibrous binder, and the degree of compression of the conductive material-coated active material being 22% or less. The fibrous binder has a crystallite size of 30.5 nm or more and 35.6 nm or less, and is mainly composed of polytetrafluoroethylene.

This utility model discloses a hoisting bracket for a finned radiator, relating to the field of finned radiator processing technology. It includes a frame and adjusting rods. A driving device is horizontally mounted at the bottom of the frame, and guide seat components are mounted at both ends of the driving device. A first limiting frame is connected to the bottom of the guide seat components, and a second limiting frame is connected to the bottom of the first limiting frame. The adjusting rods are vertically mounted on both sides of the first and second limiting frames. This hoisting bracket for the finned radiator, by symmetrically arranging adjusting rods on both sides of the first and second limiting frames, allows for a certain degree of structural extension between the first and second limiting frames. Combined with the structural mobility of the first and second limiting frames, it can stably clamp finned radiators of different structural dimensions within a certain range, facilitating hoisting and movement.

This invention relates to a myocardial repair patch based on multi-material printing, its preparation, and its application, belonging to the field of bio-3D printing and regenerative medicine technology. The invention uses PLCL and GelMA hydrogel loaded with active cardiomyocytes as bio-inks, and introduces gelatin gel as a heat buffer material. An orthogonal network structure is constructed using multi-material bio-3D printing technology to prepare a myocardial repair patch with excellent dynamic adaptability to the myocardial interface and good biocompatibility. The myocardial injury repair patch prepared by this invention achieves a structure-function integrated design through the synergistic effect of the three materials, significantly overcoming the limitations of single materials in terms of mechanical properties, biological function, or thermal compatibility. The mechanical properties of the myocardial injury repair patch prepared by this invention can precisely match those of natural myocardium, while possessing high cell activity, effectively inhibiting fibrosis, improving myocardial function, and achieving true active repair. Furthermore, the process conditions are controllable, demonstrating good translational potential.
