  • Patent number: 11313774
    Abstract: A TEM electromechanical in-situ testing method of one-dimensional materials is provided. A multi-function sample stage which can compress, buckle and bend samples is designed and manufactured. A carbon film on a TEM grid of Cu is eliminated, and the TEM grid of Cu is cut in half through the center of the circle. The samples are dispersed ultrasonically in alcohol and dropped on the edge of the semicircular grid of Cu with a pipette. A single sample is fixed on the edge of a substrate of the sample stage with conductive silver epoxy by using a micromechanical device under an optical microscope, and conductive silver paint is applied to the surface of the substrate of the sample stage; and an electromechanical in-situ testing is conducted in a TEM. This provides a simple and efficient sample preparation and testing method for a TEM electromechanical in-situ observing experiment.

  • Patent number: 10801933
    Abstract: The present invention provides a self-healing method for fractured SiC amorphous nanowires. A goat hair in a Chinese brush pen of goat hair moves and transfers single crystal nanowires under an optical microscope. On an in-situ nanomechanical test system of a TEM, local single crystal nanowires are irradiated with an electron beam for conducting amorphization transformation. Amorphous length of a single crystal after transformation is 60-100 nm. A fracture strength test is conducted on the amorphous nanowires in the single crystal after transformation in the TEM; and fracture strength of the amorphous nanowires is 9-11 GPa. After the amorphous nanowires are fractured, unloading causes a slight contact between the fractured end surfaces; and self-healing of the nanowires is conducted after waiting for 16-25 min in a vacuum chamber of the TEM. Atom diffusion is found at a healed fracture through in-situ TEM representation; and recrystallization is found in the amorphous nanowires.
