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.
Extremely dose efficient EELS spectrum image acquisition with Gatan eaSI technology
GIF Continuum K3 IS: Advanced direct detection for in-situ chemical analysis
Gatan DigitalMicrograph is a well-established software tool for performing in-situ (S)TEM experiments. This powerful capability has now been expanded to allow capture and analysis of in-situ EELS and spectrum imaging datasets. This video demonstrates the unique in-situ data acquisition and analysis capability of this advanced software platform when operated together with the GIF Continuum® K3® system.
Continuum IS: Versatile time-resolved data collection webinar
Gatan's latest spectrometer, the Continuum, enables a wide range of techniques for (S)TEM investigations. This versatility is enhanced further with the Continuum IS, where acquisition modes have been expanded to capture data continuously over time.
This webinar will present the numerous types of data that can be collected with the Continuum IS as well as the powerful tools we provide to process that data, including our redesigned IS player and Python scripting.
Continuously acquired 4D STEM and EELS spectrum images for in-situ microscopy webinar
In this webinar, we presented new tools for in-situ EELS spectrum imaging and in-situ 4D STEM. In addition to a simple interface for continuous acquisition with live drift correction, Gatan has developed a suite of tools for processing and visualizing these multi-dimensional datasets. While faster detectors make a continuous acquisition of analytical data feasible, these tools for the management of the resulting data make such experiments practical.
Auf den Spuren von Lithium im Mikrometerbereich
Lithium-Ionen-Batterien (Li) werden aufgrund ihrer herausragenden Energiedichte und geringen Masse für eine Vielzahl von Energiespeicheranwendungen eingesetzt. Es besteht weiterhin großes Potential zur Verbesserung der Kapazität und der Effizienz dieser Energiematerialien durch die Optimierung der verwendeten Komponenten und Materialien. Insbesondere durch den Mangel an geeigneten Charakterisierungstechniken auf der Mikro- und Nanoebene, sind die Abbaumechanismen und Strukturentwicklungen noch nicht ausreichend erforscht.
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.
