Implementation of compound refractive lenses for large field-of-view x-ray phase-contrast imaging during hypervelocity impact experiments Open
Synchrotron x-ray phase-contrast imaging (XPCI) offers time-resolved visualization of dynamic compression phenomena, but its intrinsically small field-of-view (FOV) limits the time that key features remain in frame. A novel approach to enl…

Deep learning for quantitative dynamic fragmentation analysis Open
We have developed an image-based convolutional neural network that is applicable for quantitative time-resolved measurements of the fragmentation behavior of opaque brittle materials using ultra-high speed optical imaging. This model exten…

A six degrees of freedom femtosecond laser system for fabrication of small-scale mechanical property specimens Open
We present the details of a novel ultra-short pulsed laser machining workstation that has been employed for high-throughput laser machining of small-scale mechanical property specimens. This system employs a six degrees of freedom hexapod …

Manufacturing Processes of a Purified Microbiome Therapeutic Reduce Risk of Transmission of Potential Bacterial Pathogens in Donor Stool Open
Background Although fecal microbiota transplant has been used to prevent recurrent Clostridioides difficile infection (rCDI), documented pathogen transmissions highlight inherent safety risks of minimally processed stool. We describe manuf…

Ballistic Impact Response of Al<sub>0.1</sub>CoCrFeNi High‐Entropy Alloy Open
In this manuscript the ballistic impact response of a high entropy alloy is demonstrated along with detailed description of the corresponding deformation and fracture mechanisms. The high entropy alloy studied could be potentially transfor…

The Role of Inclusions in the Failure of Boron Carbide Subjected to Impact Loading Open
This work investigates the importance of the microstructure of boron carbide for initiating inelastic deformation under impact conditions. Simple loading resulting from a flyer plate impact geometry is used to illustrate the importance of …

Towards predictive transferable simulations of ceramic failure in ballistic events Open
This work discusses the calibration of an advanced material model for boron carbide and then compares simulations of a ballistic impact event to highly instrumented experiments. The experiments are instrumented using flash x-ray, high-spee…

Time-Resolved Measurement of Deformation of Metal Plates Due to High-Velocity Impacts Open
A methodology is presented for analysing the rear surface deformation of metal plates impacted at ordnance velocities to hypervelocities. Ultra-high-speed imaging and Photonic Doppler Velocimetry are used concurrently to provide a real-tim…

Single‐Crystal Elastic Properties of Aluminum Oxynitride (Al <span>ON</span> ) from Brillouin Scattering Open
The Brillouin light scattering technique was used to determine experimentally the three independent elastic constants of cubic aluminum oxynitride at the ambient condition. They are , and . Its bulk modulus is 221.2 GPa . The magnitude of …
