Register to watch recording


Advances in 3D additive manufacturing techniques have enabled the production of nanostructures with remarkable mechanical properties. Using the latest 3D printing techniques, novel material structures with unique mechanical properties can be produced, such as micro- and nanolattices. Understanding the underlying characteristics of these complex new materials, such as deformation mechanisms, and how they impact structural behavior, is increasingly challenging. In this webinar, viewers will be presented with examples of how various microscopy techniques, including scanning electron microscopy (SEM), helium ion microscopy (HIM), and nanoscale X-ray imaging, have been applied to the study of nanoarchitectured lattice structures. They will also learn how these techniques have helped to solve some of the most intriguing questions related to nanomaterials.

During this webinar, the speakers will:

  • Review the latest advances in nanoscale 3D printed lattice structures
  • Present their own work involving SEM and HIM imaging methods to characterize nanolattice structures.
  • Describe the use of nondestructive 3D X-ray imaging methods
  • Discuss future directions for in situ imaging
  • Answer questions during the live broadcast!

This webinar will last for approximately 60 minutes.

Speaker bios

Ruth Schwaiger, Ph.D.

Karlsruhe Institute of Technology
Karlsruhe, Germany

Dr. Schwaiger is a senior scientist at the Karlsruhe Institute of Technology (KIT) and head of the Nanomechanics research group. She studied physics at the Technische Universität Wien in Vienna, Austria, conducted her doctoral research at the Max Planck Institute for Metals Research in Stuttgart, Germany, and obtained her doctoral degree in materials science from the University of Stuttgart in 2002. After her postdoctoral research at the Massachusetts Institute of Technology, she joined the Forschungszentrum Karlsruhe in Germany in 2004, then moved to a management consulting firm in 2007. She joined KIT in 2010. Her research interests range from deformation mechanisms in metals and the mechanics of small-scale materials and structures to biomechanics and mechanical metamaterials. Her research aims to develop a mechanism-based understanding of deformation and failure of materials, and to determine design principles impacting improved strength and damage tolerance. She has authored or coauthored more than 60 peer-reviewed articles published in renowned international journals and given more than 30 invited presentations at international conferences.

Hrishikesh Bale, Ph.D.

ZEISS Microscopy
Pleasanton, CA

Dr. Bale is a senior applications scientist in the materials science market segment at Carl Zeiss X-ray Microscopy in Pleasanton, California. He specializes in new applications development for laboratory 3D X-ray imaging techniques at both micro- and nanoscale. His research focus lies in the area of 3D diffraction contrast tomography and in situ micro- and nanomechanical testing using X-ray computed tomography. He has a background in materials science and mechanical engineering, with over a decade of experience in synchrotron X-ray microscopy and tomography, and is deeply interested in expanding the frontiers of in situ imaging under extreme service conditions as well as developing multimodal micro- and nanoscale 3D-imaging solutions. Before joining ZEISS in 2014, he held a joint postdoctoral scholar position at the Lawrence Berkeley National Laboratory and the University of California, Berkeley in the Materials Science and Engineering Department, where he worked as part of the National Hypersonic Science Center. He received his Ph.D. in materials science from Oklahoma State University in 2010 with a focus on microscale residual stress determination using synchrotron Laue microdiffraction techniques.

Jackie Oberst, Ph.D.

Washington, D.C.

Dr. Oberst did her undergraduate training at the University of Maryland, College Park, and her Ph.D. in Tumor Biology at Georgetown University, Washington D.C. She combined her interests in science and writing by pursuing an M.A. in Journalism from the Philip Merrill College of Journalism at the University of Maryland, College Park. Dr. Oberst joined Science/AAAS in 2016 as the Assistant Editor for Custom Publishing. Before then she worked at Nature magazine, the Howard Hughes Medical Institute, The Endocrine Society, and the National Institutes of Mental Health.
