Abstract: An electronic device includes at least one processor, at least one memory storing a model based definition (MBD) representing a model of a part, and an artificial intelligence (AI) client service. The AI client service, in response to execution by the at least one processor, is configured to receive inspection data corresponding to a cut part being fabricated based on the model of the part, compare the received inspection data to the MBD to determine any deviations of the cut part from the MBD, determine whether the cut part is defective based on the comparison, and update a digital thread corresponding to the part when the cut part is determined to be defective.

Abstract: A method of producing graphene powder includes the heat treatment of a graphitizable polymer film to at least 2000 degrees C. to form a heat treated film having a substantially turbostratic graphitic structure. The heat treated film is then sheared along a plane substantially parallel to a major surface of the heat treated film to form a particulate having a thickness less than 100 nanometers.

Abstract: A chemical vapor deposition (CVD) system for forming carbon nanotubes from solid or liquid feedstock. The system includes a reactor including a housing that includes an inlet and an outlet. The housing defines an interior for receiving the feedstock, and the interior receives inert gas. The CVD system includes a first stop valve in flow communication with the inlet and a second stop valve in flow communication with the outlet. The first and second stop valves seal the inlet and the outlet such that a static environment is formed in the interior when reacting the feedstock. A heater heats the interior to a temperature such that the feedstock is vaporized, thereby forming vaporized feedstock. The CVD system further includes a controller coupled in communication with the first and second valves and the heater. The controller is configured to selectively actuate the first and second valves and the heater.

Abstract: The present invention is directed to methods for assessing the purity of carbon nanotube (CNT) compositions, specifically, a method for assessing the presence of contaminants in a CNT composition using polyaryl ethynyl (PAE) conjugate polymer as an indicator material. Additionally, compositions and kits comprising a polyaryl ethynyl (PAE) conjugate polymer are also provided.
