  • Patent number: 12487578
    Abstract: A device for multi-energy field induced atomic-scale CNC machining in an environmental atmosphere comprises an electromagnetic shielding chamber and a control mechanism, wherein an environmental chamber is arranged in the electromagnetic shielding chamber, a workpiece platform is arranged at the bottom of the environmental chamber, and a nanotool driven by a nanotool actuator is arranged at the top of the environmental chamber, and a gas inlet and a gas outlet which are connected to the environmental chamber are formed in the electromagnetic shielding chamber; and the control mechanism is used for controlling the workpiece platform and the nanotool actuator and applying energy fields including a force field, a temperature field, an electric field, an optical field and a magnetic field. The device has the advantages of atomic precision, high efficiency, low cost and good universality.

  • Patent number: 12325017
    Abstract: A photoelectric fluid field cluster catalytic method for atomic-scale deterministic processing, comprises the following steps: selecting nanoparticles with photocatalytic activity as a photocatalytic medium, and using a photoreduction method to realize the precipitation of metal nanoparticles on a surface of the photocatalytic medium, thus creating photoelectrocatalytic clusters; illuminating a coupling area between a surface to be processed of a workpiece, the photoelectrocatalytic clusters and a flexible tool with a catalytic light source, and simultaneously applying a bias voltage to a conductive tray of the workpiece; and applying a normal load to a flexible tool head and setting a rotation speed to generate a hydrodynamic pressure to drive a polishing solution to flow, thus enabling controllable removal with atomic-level precision.
