Award Winning Adhesives Researcher Credits ACMAL Expertise

Adhesive-coated pillars made using a a silicon template provided by Microfabrication Facility Managing Director Chito Kendrick. The morphology was visualized using the ACMAL E-SEM with the help of Lab Supervisor Jerry Anzalone.

The Bhakta Rath Research Award honors a graduate student and faculty mentor for in-depth work with social impact. The 2019 winners are two biomedical engineers with a sticky past.

A smart adhesive doesn’t adhere all the time. In 2015, when Ameya Narkar started his doctoral research with Bruce Lee, associate professor of biomedical engineering at Michigan Technological University, the two turned to biological sources for a glue that could be turned on and off.

Q: How have your methods helped make the project successful?

Ameya Narkar: Our biomedical engineering department is full of approachable experts. It’s a small team and an effective one. I could walk down to a faculty member’s office and ask for advice when our project branched into areas beyond our lab’s expertise. Plus, I was able to work closely with the people in the Applied Chemical and Morphological Analysis Laboratory and the microfabrication facility. Collaboration is essential to successful research.

Gold Quantum Dots Observed with S-TEM

Gold Quantum DotYoke Khin Yap, professor of physics at Michigan Tech, led the study. He explains that the behavior his team observed — atomic-level manipulation of gold quantum dots — can be seen with a scanning transmission electron microscope (STEM). The STEM’s high-powered beam of electrons enables researchers like Yap to watch atomic movement in real-time and the view reveals how gold atoms interact with the surface of boron nitride nanotubes. Basically, the gold atoms glide along the surface of the nanotubes and, they stabilize in a hover just above the hexagon honeycomb of the boron nitride nanotubes.

S-TEM Images for Al-Sc Alloy

S-TEM Al Sc imagesPaul Sanders, Patrick Horvath Endowed Associate Professor of materials science and engineering, and materials science and engineering graduate student Yang Yang, are trying to strengthen aluminum by adding scandium to it.

The aberration-corrected FEI Titan Themis scanning transmission electron microscope (STEM) in Michigan Tech’s Applied Chemical and Morphological Analysis Laboratory, makes an electron beam less than an atom in width. This allows researchers to scan through samples one atom column at a time. Additionally, the lab has a SuperXTM X-ray detector, which is an array of four detectors to collect four times more X-rays than a conventional detector.

Combining the two techniques, researchers can element map at atomic resolution.

S-TEM Provides Insight to Alloy Behavior

S-TEM MappingMaterials Science doctoral candidate Deji Fadayomi, and professors Paul Sanders and Gregory Odegard, are working on these precipitation-strengthening mechanisms in aluminum-based alloys. This atomic-resolution image and elemental maps of precipitates were obtained in aberration-corrected scanning transmission electron microscope (AC-STEM) at Michigan Tech’s Applied Chemical and Morphological Analysis Laboratory (ACMAL) to better understand alloy behavior at an atomic level.

S-TEM Live Lab Tour Video Spring 2018

Michigan Tech faculty and staff presented a live tour of the FEI 200kV Titan Themis S-TEM facility on Facebook last Wednesday, February 14, 2018.

Introducing the tour was Kelley Christensen, science and technology publications writer for University Marketing and Communications. Steve Hackney, a professor in the Department of Materials Science and Engineering, talked about the atomic scale science and engineering taking place in the housing facility, the Advanced Technology Development Complex (ATDC).

ACMAL Director Owen Mills discussed sample preparation procedures. S-TEM specialist Pinaki Mukherjee demonstrated operation of the instrument and its capabilities.
