  • Patent number: 12241174
    Abstract: A method used to repair a workpiece through a combination of laser and an electrochemical reaction is provided. A tool anode is arranged on the back side of the workpiece and is spaced therefrom. A laser beam is focused on an outer surface of the workpiece to realize localized repairing on the back side. The method realizes localized coating repairing on the back side of the workpiece through coordination between the thermal effect of the laser and the electrochemical deposition based on the characteristic of high thermal conductivity of the workpiece. The electrodeposition reaction does not occur in regions that do not need to be repaired. The operating process is simple, the cost of the plating solution is largely reduced, and the problem that the coating on the inner wall of the thin-walled workpiece is difficult to repair due to stripping is solved.

  • Publication number: 20250059553
    Abstract: A gene related to biosynthesis of ergothioneine is provided. Based on five synthesis genes of ergothioneine in Mycobacteroides abscessus, only an encoding sequence of each of the five genes is retained, and a gene structure of an encoding region in each gene is optimized to obtain genes related to the biosynthesis of the ergothioneine that are stably expressed in rice. These genes have sequences set forth in SEQ ID NO: 1 to SEQ ID NO: 5, and encoded proteins thereof have amino acid sequences set forth in SEQ ID NO: 6 to SEQ ID NO: 10. The gene is transferred into rice to construct a transgenic rice molecular farm to produce the ergothioneine. As a molecular farm, rice seeds do not contain alkaloids or allergens that are harmful to the human body. Moreover, biosynthesized ergothioneine shows the advantages of easy extraction and processing and of low production cost.
