Abstract: A battery recycling process recovers lithium from nickel-rich cathode material in a recycling stream of end-of-life batteries. A dilute acid leach of a high nickel content cathode material contains a mixture of sulfuric acid based on a molar quantity of lithium in the cathode material. The highly selective leach generates a lithium rich solution with a small amount of nickel removable by nanofiltration to achieve a highly efficient recovery of the lithium contained in the recycling stream. A quantity of the leach acid based on the lithium content and a quantity of water based on a total black mass of the recycling stream results in a highly selective, near pure lithium leach when the recycling stream results from high nickel NMC batteries such as 811.

Abstract: A yarn including a plurality of twists formed by twisting single fiber strand or multiple fiber strands; and fiber grooves, which are spaces formed between the twists, to provide three-dimensional growth spaces and migration paths for cells. Accordingly, a cell proliferation rate and cell viability may be enhanced by creating microenvironments suitable for migration, proliferation and differentiation of cultured cells. In addition, cell clusters having more uniform shapes may be easily implemented by forming the proliferation spaces and migration paths for the cultured cells as similar as possible to each other in each scaffold. Further, the cells cultured thereby can be cultured in a suitable shape and structure to be applied to an in vitro experimental model or transplanted into the body of an animal, and can be widely applied in various products used in a cell culture or tissue engineering field.

Abstract: The disclosure relates to a method for forming nanofiber-assembled filaments in which an aromatic polyamide nanofiber suspension is first formed into wet nanofiber-assembled filaments via wet-spinning and protonation in a coagulation medium including at least one proton donor along with a non-solvent for the aromatic polyamide. The wet nanofiber-assembled filaments are then drawn to reduce/remove voids in the nanofiber-assembled filaments and improve the mechanical properties of the assembled filaments. The method can be used as a recycling method for used aromatic polyamide fiber/filament materials in which the recycled filaments have high/good mechanical properties relative to virgin filament materials.

Abstract: An apparatus enables a high-bandwidth 4-way data serializing (4:1 serializer) digital-to-analog converter. The apparatus uses active inductor-based bandwidth extension technique for two-stage driver enabling design of quarter-rate 4-way data serializing transmitter. The 4:1 serializer output bandwidth is extended by gate-resistor-peaked n-type transistor load working as an active inductor. A current steering switch with current source is used as the final driver. The 4:1 serializer includes a pulse width tuning technique with tunable ground voltage on the ground terminal of a pulse generator to tune an effective threshold voltage of the pulse generator. A Bessel-like LC filter is coupled to an output of the 4:1 serializer. The filter includes shunt peaking paths that provide zeros, which natively cancel large parasitic capacitance at a shunt peaking node. As such, active and passive devices including driver circuitry, ESD diodes, and any other sensing circuitry are flexibly added on any LC filter nodes.

Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.
