Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, a cutting structure may disrupt continuity of the OLED layers. The cutting structure may have two undercuts to disrupt continuity of at least some of the OLED layers. The cutting structure may include a conductive portion that provides a cathode voltage to a cathode layer for the OLED pixels.

Abstract: Disclosed is a method for removing aluminum in a ternary battery material leachate by adopting an extraction method, which comprises the following steps: (1) saponification: mixing an extraction solvent with a saponifying agent to obtain a saponified extraction solvent; (2) extraction: mixing the ternary battery material leachate with the saponified extraction solvent to obtain a loaded organic phase and a raffinate; (3) back extraction: mixing the loaded organic phase with a back-extraction agent, followed by performing a back-extraction to obtain an organic phase and a back-extraction solution; the extraction solvent comprises an extracting agent and a diluent. The extraction method is adopted to separate nickel, cobalt, manganese and aluminum, having the advantages of less heavy metal entrainment, short process flow, and high metal recovery rate. The extraction rate of the aluminum can reach 97.42 percent.

Abstract: Test fixture grips for testing quasibrittle materials, such as fiber-polymer composites are provided having increased mass and stiffness relative to standard test grips to provide for obtaining postpeak measurements. The design is based on static analysis (using the second law of thermodynamics), confirmed by dynamic analysis of the test setup as an open system. Dynamic analysis of the test setup as a closed system with PID controlled input further indicates that the controllability of postpeak softening under CMOD control is improved not only by increasing the grip stiffness but also by increasing the grip mass.

Abstract: Disclosed is a tool bit for an ultrasonic osteotome, comprising a head portion of the tool bit, an arbor and a tail portion. One end of the arbor is connected with the head portion of the tool bit, and the other end of the arbor is connected with the tail portion. The tail portion is connected with an ultrasonic main machine through an ultrasonic transducer. The head portion of the tool bit has a flat structure. A front-end surface of the flat structure is a smoothly curved surface, and an upper surface or both an upper and a lower surface of the flat structure are formed with knurls, which extends from a front end of the flat structure towards the arbor and covers the flat structure to form a flat-file type tool bit.
