It is not a production description, it is a description of samples preparation for EM (Electron Microscopy) for control or whatever purpose. To preserve structure of organic samples in vacuum of electron microscope, before making micrographs organic samples iced in amorphous ice (ethane or propane one), that is why it is named Cryo-EM, and that is why liquid ethane mentioned. Pretty usual process, really.
Gold grids covered with graphene oxide is a new fashionable (and expensive) gadget for EM. Really, for EM with mentioned resolituion, cheap copper grids covered with graphite is more than enough.
What you cited here looks more like evidence of money laundering or just theft of company money, instead of what you thought.
