  • Recovering atomic-scale chemistry from fused multi-modal electron microscopy
    Patent number: 12498336
    Abstract: Systems and methods for fused multi-modal electron microscopy are provided to generate quantitatively accurate 2D maps or 3D volumes with pixel/voxel values that directly reflect a sample's chemistry. Techniques are provided for combining annular dark field detector (ADF), annular bright field (ABF) and/or pixelated detector image data and energy dispersive X-rays (EDX) data and/or electron energy loss spectroscopy (EELS) data for a sample and generating chemical 2D and 3D maps by applying minimization optimization process.

  • STABLE ELECTRON MICROSCOPY SPECIMEN HOLDER OPERATING AT LOW TEMPERATURES
    Publication number: 20250191876
    Abstract: In one aspect, a specimen holder includes a first end configured to attach to a cooling device and a second end configured to be inserted into a microscope; a section with a sample tip at the second end; an interface between the first end configured to attach to the cooling device and the section with the sample tip; and an internal thermal connection section configured to be in thermal contact with a cold finger of the cooling device when the specimen holder is attached to the cooling device and extending through the section with the sample tip to the sample tip.
