Ajay Krishnamurthy is a Guest Researcher with the Security Technologies Group as part of the Materials Measurement Laboratory (MML) at the National Institute of Standards and Technology. He has a background in carbon based nanomaterials specially in synthesis and application of graphene and carbon nanotubes for various industrial applications such as corrosion resistance coatings, hierarchical composites and electrodes for battery applications. His current research focus is on two major topics.
Dr. Krishnamurthy is involved in addressing measurement challenges associated with novel hierarchical nanocomposite architectures for use in structural applications. He works on various aspects of the project that include nanomaterial processing and incorporation, composite manufacture, understanding structure-property relationships (mechanical, viscoelastic and polymer dynamics, cure kinetics) and evaluating degradation characteristics.
Positron Annihilation Lifetime Spectroscopy (PALS)
Dr. Krishnamurthy is part of a multi-disciplinary team of researchers that address the material and the measurement based challenges associated with developing PALS at NIST. He is actively involved in the measurement process (experimental and analysis), digitization of the spectrometer and developing novel in-situ measurement capabilities. He also serves as a nominated U.S. expert on the ANSI-Accredited U.S. TAG ISO/TC 229 Nanotechnologies that is involved in developing the ISO Positron Annihilation Lifetime Standard.
