Zoz Simolayer CM01-2lm high-energy horizontal ball mill is customized for cryogenic milling by Matsys, Inc. It has a 2L capacity chamber that can mill up to ~250g of powder per run. The wall of the milling chamber is externally cooled via a 240L dewar of liquid nitrogen or a CORIO CP-1000F chiller that has a range between -50 °C to 200 °C. The roughing vacuum pump and compressed gas lines enable milling in controlled atmospheres (e.g., Ar). The attached thermocouples and pressure sensors ensure that proper milling temperatures are achieved and maintained, and they monitor any unexpected pressure spikes. Another useful design feature is a small extraction tube where powders can be removed from the mill during intermediate milling stages, which can assist in evaluating temporal behaviors of the milling process without needing to create a new batch of powder. Overall, this mill is optimal for controlled experimentation of large-scale mechanochemistry experiments.

The Quanta™ 3D DualBeam™ FEG FIB-SEM combines a Focused Ion Beam (FIB) with a high-resolution Field Emission Gun Scanning Electron Microscope (FEG-SEM). This combination provides enhanced 2D and 3D materials characterization and analysis for a wide range of samples. A focused Ga Ion beam allows for micro and nano-scale cutting of material during TEM sample preparation, EBSD surface milling, and automated milling scripts for micro-pillar patterns. Additionally, the FIB provides a “slice and view” technique that allows for 3D reconstruction of a sample, providing the ability to image and analyze subsurface features. Featuring three imaging modes – high vacuum, low vacuum and ESEM, it accommodates the widest range of samples of any SEM system. The Quanta 3D FEG’s novel, field-emission electron source delivers clear and sharp electron imaging and increased electron beam current enhances EDS and EBSD analysis.
