  • Patent number: 12254926
    Abstract: Implementations described herein relate to a memory device with a fast write mode to mitigate power loss. In some implementations, the memory device may detect a condition associated with power supplied to the memory device. The memory device may detect one or more pending write operations to be performed to cause data to be written to memory cells of the memory device. The memory device may switch from a first voltage pattern, previously used by the memory device to write data to one or more memory cells of the memory device, to a second voltage pattern based on detecting the condition and based on detecting the one or more pending write operations. The memory device may perform at least one write operation, of the one or more pending write operations, using the second voltage pattern.

  • Publication number: 20250075195
    Abstract: Provided are an esterase mutant and the use thereof. The esterase mutant obtained by means of rational design and several rounds of evolution screening with enzymes on the basis of an amino acid sequence as shown in SEQ ID NO: 1 is changed in terms of protein structure and function compared with a wild-type esterase; in practical use, the catalytic activity and/or stereoselectivity of the esterase mutant is greatly improved; and when a system contains some organic cosolvents, the esterase mutant still has relatively stable catalytic activity and/or stereoselectivity. In addition, the improvement of the catalytic activity and/or stereoselectivity of the esterase mutant reduces the use amount of the enzyme to a certain extent and reduces the difficulty of post-treatment, and therefore the esterase mutant is suitable for industrial production.
