In the Lilliputian world of nanofabrication, where billions of microscopic circuit elements are sculpted or imprinted on a fingernail-sized silicon chip
Recent advances in additive manufacturing (AM) have positioned metals and polymers as two key materials. Typically, AM of these two materials involves incompatible methods and conditions. The novel multifunctional polymer-metal composites in this project incorporate low-melting alloys with
Metal additive manufacturing (AM) is not used in fatigue and fracture critical applications despite industrial need. The goal of this project is to enable confident use of metal AM in critical applications through: Advancing metrological practice for AM-specific performance metrics encompassing the
The STG develops the methods and metrology that will lead to the understanding of the structure-property relationships of hierarchical composites in real medical PPE or protective applications, which heretofore has been lacking. This work establishes in situ monitoring of advanced manufacturing
We are developing and applying the following advanced tools to measure the structure, dynamics, and performance of polymer-based membranes and sorbents: Vibrational Spectroscopy We have developed a custom-built tandem quartz crystal microbalance (QCM), which measures total mass uptake of adsorbed

This study evaluates the material properties of an X100 pipeline steel extracted from an experimental transmission pipeline section placed into service in the
This in-situ indentation system can be integrated into electron microscopes as well as being run in other unusual setups. With a load capacity of 150 mN, this
The TA Instruments RPA elite rubber process analyzer (RPA) is a strain-controlled rotational shear rheometer for the characterization of polymers, composites
The Security Technologies Group has a 4-m-tall drop tower that can be configured for a wide variety of impact and impact-related testing. This drop tower is
