Imaging fast reactions and nanoscale growth webinar

Presentation courtesy of Eric Stach, Brookhaven National Laboratory

During this webinar Dr. Stach will describe the impact of K2 IS direct electron detectors for the field of materials science. In particular, the ability to image reactions of nanoscale volumes directly in the electron microscope at high speeds will increase our knowledge of the science of materials growth, impacting fields such as catalysis and materials discovery and design. The webinar will also address the issues surrounding large data handling for these experiments.

3DED: A brief overview of data collection, and data analysis

The determination of precise atomic arrangements in a crystal material is the key to understanding the structure-property relationship, and it will further facilitate synthetic designs of new materials. In the past decades, the structure determination of submicron/nanometer crystals has been achieved via 3D electron diffraction (3DED). This technique is also known as continuous rotational electron diffraction (CRED) or MicroED (microcrystal electron diffraction.

Capturing low-dose images, in-situ video, and diffraction data with the Metro counting camera

Gatan’s latest counting camera, Metro, produces excellent results at low dose rates and low to moderate accelerating voltages (60 – 200 kV). In this webinar, we show images from zeolites and MOFs, as well as diffraction patterns and 4D STEM datasets from 2D materials. We demonstrate the in-situ capabilities of the camera, which can capture video datasets at up to 41 frames per second at full 2k x 2k resolution.

DualEELS: The importance of low-loss correction of electron energy-loss spectroscopy data

Nanoscale characterization of Li metal batteries enabled by cryogenic lift-out

Developing methods for electron-transparent specimens without inducing artifacts has become significantly important for the high-resolution characterization of battery materials. During this webinar, we introduced our recent approach (cryogenic-lift-out) to generate lamellae with cryogenic ion microscopy and talked about the effects of xenon ion beam on lithium metal batteries through the usage of cryogenic (S)TEM. We also showed the capability of the Metro direct detection counting camera to pull out the diffraction information that helps to identify the ion beam effect.

Determining Lithium Content by the Composition by Difference Method

Lithium (Li)-ion batteries have been adopted for a wide range of energy storage applications due to their outstanding energy density and low mass compared to other technologies. However, there remains considerable scope for energy capacity and efficiency improvements by optimizing devices and materials used in their construction. In particular, microstructural and compositional analysis has proven challenging at the micro- and nano-scales with structure evolution and degradation mechanisms due to lack of understooding at these length scales.
