Abstract: Methods for preparing imaging samples by applying a liquid or semiliquid substance to a substrate surface in order to mitigate the deleterious effects of vacuum and other conditions used for sample preparation, thereby preserving the structure of at least a portion of deposited samples. These methods are useful for MS-based electron microscopy (EM) sample preparation at room temperature, but are also applicable to other imaging methods. These methods also enable transmission electron microscopy (TEM) structural confirmation of ions passing through a mass spectrometer. Additionally, only entry-level negative staining techniques for TEM are required, making this technique much more widely available than cryogenic electron microscopy (cryo-EM).

Abstract: A method generates automated discovery of new scientific formulas. The method includes receiving a background theory associated with a phenomenon being studied. The processor receives a set of training data associated with the phenomenon being studied.
