  • Publication number: 20240161818
    Abstract: The invention provides a layout pattern of static random access memory (SRAM), which at least comprises a plurality of gate structures located on a substrate and spanning the plurality of fin structures to form a plurality of transistors distributed on the substrate, wherein the plurality of transistors comprise two pull-up transistors (PU), two pull-down transistors (PD) to form a latch circuit, and two access transistors (PG) connected to the latch circuit. In each SRAM memory cell, the fin structure included in the pull-up transistor (PU) is defined as a PU fin structure, the fin structure included in the pull-down transistor (PD) is defined as a PD fin structure, and the fin structure included in the access transistor (PG) is defined as a PG fin structure, wherein a width of the PD fin structure is wider than a width of the PG fin structure.

  • Publication number: 20240128531
    Abstract: The present disclosure discloses a method for recycling all types of lithium batteries. First, the lithium battery waste is acid-leached to obtain a solution containing most of metal ions. After filtering, the solution is separated from the remaining solids, and then the obtained solution is subjected to separate precipitation many times. After separately adjusting the pH value of the solution many times, adding precipitants with a high selectivity ratio, and matching with filtration and separation reaction, all ions in the lithium battery waste are sequentially precipitated in forms of iron phosphate (FePO4), aluminum hydroxide (Al(OH)3), manganese oxide (MnO2), dicobalt trioxide (cobalt oxide, Co2O3), nickel hydroxide (Ni(OH)2), and lithium carbonate (Li2CO3).

  • Patent number: 9068056
    Abstract: Disclosed is layered double hydroxides (LDH) used to catalyze the polymerization of polyethylene terephthalate (PET). The LDH of a catalyst amount may efficiently reduce the PET polymerization period and further be uniformly blended into the PET product to form composites. Compared with the pure PET, the composite including LDH has better properties such as mechanical properties, linear expansion coefficient, barrier, thermal stability, and transparency. In addition, the LDH in the composite is safer than conventional heavy metal catalysts, especially when applied to food or drink packages.
