With a nanometer-sharp probe capable of delicate interaction with a limitless array of materials, SPM methods such as Atomic Force Microscopy (AFM) can aid in characterizing a wide range of materials in diverse environments from vacuum to biological serums. The atomic force microscope is operated in

Scanning Probe Microscopy Calibrations and Standards

Ongoing

The Nanomechanical Properties Group has expertise in a wide variety of SPM techniques, especially atomic force microscopy (AFM); however, the main research thrust for the Group’s standards project area deals with accurate cantilever stiffness calibration and the use and development of AFM methods

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing

Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

Structural Metrology of Advanced Manufacturing Processes

Ongoing

Understanding material structures in advanced manufacturing is crucial because it enables precise control over material properties, leading to improved performance, efficiency, and cost-effectiveness in production processes. However, this understanding poses many challenges, such as the

Sustainable Metals Processing and Alloy Development

Ongoing

Foundational measurement science is being developed to support sustainable innovations through alloy design and optimization. The integration of experiments and computational thermodynamics and kinetics tools with mechanistic models enables the prediction of key processing-structure-property

Systems Integration for Additive Manufacturing

Ongoing

Objective: Deliver an information systems architecture, including metrics, information models, and validation methods to shorten the design-to-product cycle time in additive manufacturing (AM). Technical Idea: AM adopters are increasingly facing many of the challenges faced by early computer-aided
