Disclosed is a selective field-assisted machining system. The system includes a micron-level high-speed identification module, an in-situ laser assisted module, an ultrasonic vibration module, an energy field loading high-speed control module, and a diamond tool. The micron-level high-speed identification module is used to quickly identify the type of a material substrate of a workpiece to be processed, process the identification information into a corresponding control signal, and send same to the energy field loading high-speed control module to implement selective processing of the workpiece to be processed, i.e. to process brittle particles using in-situ laser assisted machining and to process a soft metal substrate using ultrasonic vibration processing. In the present invention, ultra-precision cutting of brittle particles and a soft metal substrate can be completed at the same time in a single processing process.

The present disclosure belongs to the technical field of biosensors and particularly provides a construction method for a photocathode indirect competition sensor and an evaluation method. The construction method includes: using Z-type BiO/CuBiOas a sensing platform; calculating a photoinduced electron Z-type transfer path and an energy band structure of BiOand CuBiOusing a density functional theory (DFT); and constructing a BiO/CuBiO-based biosensor. A photoelectrochemical (PEC) photocathode biosensor based on a BiO/CuBiOheterojunction prepared through the solution has good repeatability, reproducibility, stability, and specificity for detecting a target. The PEC biosensor constructed in the solution of the present disclosure has a broad application prospect in the fields of healthcare, environment, and food.

Provided are Ti(C,N)-based cermets with NiAl and Ni as binder and a preparation method thereof. The Ti(C,N)-based cermets are prepared by raw materials subjected to ball-mill mixing, die forming, vacuum degreasing and vacuum sintering, wherein weight percentage of each chemical component of the raw materials is as follows: TiC 34.2&#x2dc;43%, TiN 8&#x2dc;15%, Mo 10&#x2dc;15%, WC 5&#x2dc;10%, graphite 0.8&#x2dc;1.0%, Ni 20&#x2dc;24%, and NiAl powder containing B 6&#x2dc;10%. Ni powder and NiAl powder containing B are used as binder. The Ti(C,N)-based cermets feature in excellent corrosion resistance, oxidation resistance and mechanical properties at high temperature, has a hardness of 89.0&#x2dc;91.9 HRA, a room temperature bending strength of 1600 MPa or more, and a fracture toughness of 14 MPa&#xb7;mor more, and is applicable for manufacturing high-speed cutting tools, dies and heat-resisting and corrosion-resisting components.
