ENG 1101 Exploration: Exploring Nanoscale Science & Technology Through Carbon Nanotubes

This hands-on exploration section introduces students to the interdisciplinary field of nano-science & technology through an example exploration of carbon nanotubes. Students will learn about and explore their synthesis, processing, characterization and applications in state of the art research facilities, which include the Materials Physics and Laser Physics Laboratories, Atomic Force Microscopy laboratory, and Scanning Electron Microscopy laboratory.

October 20, 2004

PowerPoint Presentation (MTU Only Access, 10.7 Mb)

Presentation by Dr. John Jaszczak in Fisher Hall

Pre-Exploration Questionnaire

Students begin with a pre-exploration questionnaire to determine their knowledge about and interest in nanotechnology.

Special About Nanotechnology

What's So Special About Nano? Students are given a brief introduction about nanotechnology by John Jaszczak, Associate Professor of Physics.

 

Demonstration by Dr. Yoke Khin Yap in the Materials Physics and Laser Physics Laboratory

Dr. Yap Showing CNT

Yoke Khin Yap, Assistant Professor of Physics, rolls an illustrated layer of graphite (called graphene sheet) into a tube to demonstrate bonding in carbon nanotubes.

CNT Sample

Students examine real samples of carbon nanotubes.

Yap Demonstrating PLD System

Dr. Yap demonstrates near the Dual-RF-plasma Pulsed-Laser Deposition (PLD) System in the Materials Physics and Laser Physics Laboratory.

Sample Preparation Chamber

Chamber for characterizing electronic properties of carbon nanotubes.

 

Demonstration by Mr. Owen Mills in the FE-SEM Laboratory

Group in FE-SEM Lab

Owen Mills, Electron Optics Engineer and manager of the Field Emission Scanning Electron Microscope lab, demonstrates microscopy on a carbon nanotube sample.

Hitachi S-4700 FE-SEM

Hitachi S-4700 FE-SEM, located in the Minerals and Materials Engineering Building.

Microscope Sample

Mr. Mills talks about mounting samples, microscope computing hardware and software, and panning and zooming of images.

Scouting the Sample

The sample is examined for interesting features. Image astigmatism and sample drift are issues.

FEM Sample Scale 1

Sample at 20 micron scale.

FEM Sample Scale 2

Sample at 0.57 micron scale.

 

Demonstration by Dr. Howard Wang in the AFM Laboratory

AFM Lab

Howard (Hao) Wang, Assistant Professor of Materials Science and Engineering, discusses the Atomic Force Microscopy lab.

AFM Image Display

Students look at images of carbon nanotubes.

AFM Image Closeup

AFM image close-up. The AFM lab is located in the Minerals and Materials Engineering Building.

AFM Real Examples

Dr. Wang shows features of dispersed single-walled carbon nanotubes.

AFM Lab Before Survey

After the AFM lab demonstration, the students will take another written questionnaire to reassess their knowledge of and interest in nanotechnology.
