Abstract: The present application provides a firmware mode switching method and apparatus, an electronic device, and a storage medium, belonging to the technical field of computers. The method includes: receiving a firmware activation command sent by a host, where the firmware activation command is configured to instruct a target solid state disk to write firmware of a first mode into a non-volatile storage medium corresponding to a target slot; determining whether the first mode is consistent with a current firmware mode of the target solid state disk, performing, in response to inconsistency, a firmware switching check according to the firmware activation command, and writing the firmware of the first mode into the non-volatile storage medium corresponding to the target slot after the firmware switching check pass; executing a reset operation, and loading the firmware of the first mode; and initializing the firmware of the first mode.

Abstract: A process to produce dense nanocrystalline composites such as ceramic bodies, coatings and multi-layered devices with uniform microstructure is disclosed. The invention utilizes sol-gel solutions to reduce agglomeration of nanocrystalline powders in the production of “green bodies” or intermediate products. This novel use of sol-gel solutions also reduces grain growth and porosity in products during sintering. In finished products, final grain sizes are typically less than 100 nm with densities of the final products approaching 99.5% of theoretical densities. In addition, sintering temperatures required are lower than those in conventional methods, typically less than 1,100° C. While FIG. 1 shows one application of this novel process, this invention has wide application in the manufacture of many other products, particularly for composite coatings and in the production of nanodevices.
