Tensile Testing Laboratory: Nanoscale and Macroscale Metal Samples
24 Nov 2015 | Teaching Materials | Contributor(s): Aisling Coughlan, Kendra A. Erk, David Ray Johnson, Tanya Faltens, Alejandro Strachan, Heidi A Diefes-Dux
This document is an updated (Fall 2015) sophomore materials science and engineering tensile testing laboratory handout that introduces students to the atomic-level processes that are responsible for plastic deformation. By performing standard tensile tests on a ductile metal in conjunction with molecular dynamics (MD) simulations, the goal is to help students understand the relationship between macroscopic plastic behavior and the underlying atomic-level mechanisms that involve dislocation...

Reproducing DFT calculations of Al2O3/GaAs interface structure and Fermi level pinning
18 Mar 2015 | Presentation Materials | Contributor(s): Alejandro Strachan
The goal of this resource is to demonstrate how to reproduce the results of the following research paper using the nanoMATERIALS SeqQuest DFT simulation tool on nanoHUB. In addition to reproducing the paper's results, users can run variations of the simulation to explore the physics and conduct their own research. Hegde, G., Strachan, A., & Klimeck, G. (2011). Role of surface orientation on atomic layer deposited Al2O3/GaAs interface structure and...
nanoHUB Materials Simulation Homework: Engineering the Yield Stress of a Material
26 Feb 2015 | Teaching Materials | Contributor(s): Marisol Koslowski, Tanya Faltens
This homework assignment uses the nanoplasticity lab simulation tool to enable students to explore how grain size and the competing plastic deformation mechanisms of dislocation motion and grain boundary sliding affect the yield stress of a sample. Students create conditions that lead to both the Hall-Petch and inverse Hall-Petch effects, and are asked to explain how the factors involved can lead to these two different results.
Exploration of the Oxidation Rate of Silicon Wafers via Simulation
04 Nov 2014 | Teaching Materials | Contributor(s): Tanya Faltens
This teaching resource is designed for instructors who would like to introduce exploration through simulation into their lessons on silicon oxidation. Step-by-step instructions are provided for running the process lab oxidation simulation, and guiding questions are provided that should help students discover important trends in the oxidation rate when different process parameters are changed.
Exploring Thin Film Interference Colors through Simulation
04 Nov 2014 | Teaching Materials | Contributor(s): Tanya Faltens
This resource will guide instructors and independent learners through the process of simulating the reflections off of a thin film using the S4: Stanford Stratified Structure Solver simulation tool. Examples of a freely standing thin film (a soap bubble) and a thin film of silicon dioxide on a silicon wafer are presented. Some reference to thin film interference and the colors average humans perceive when viewing different energies (or wavelengths) of light are...
Useful nanoHUB Features
18 Aug 2014 | Downloads | Contributor(s): Tanya Faltens
These short pdf documents describe how to make the best use of nanoHUB features that instructors (and others) might find useful. Topics covered include creating and working with groups, sharing a tool session, working with projects, searching for resources, creating a collection, asking for help, submitting wishes, and contributing new content. A second document describes how to personalize your nanoHUB experience via your personal nanoHUB space and Dashboard.

Displays drain current as a function of source-drain voltage for different values of gate voltage, gate dimensions, substrate material, and oxide material in an n-type MOSFET.
Using nanoHUB to Introduce Elementary and Middle School Students to Models and Simulations
25 Mar 2014 | Teaching Materials | Contributor(s): Tanya Faltens
This is a combination hands-on and simulation activity that will teach middle school students about the function and importance of modeling and simulations in science and engineering while learning about three important carbon nanostructures: graphene, bucky balls, and carbon nanotubes. The activity uses the Crystal Viewer simulation tool in nanoHUB, and has been used with many different ages of student at NanoDays at the Birck Nanotechnology Center at Purdue.

Quick and Easy Guide to Carbon Structure Simulations using Crystal Viewer Tool
30 Sep 2013 | Teaching Materials | Contributor(s): Tanya Faltens
These are step-by-step instructions for creating simulations of carbon nanostructures:
- buckly ball
- carbon nanotubes
- graphene sheets
These instructions will allow teachers to run simulations that students can use along with, or instead of, building 3D models of structures.
In NanoDays 2013 at Purdue, students in the 4th grade quickly learned to run these simulations, and were able to teach other students how to enter parameters and simulate new structures.
This is a very...
Unit Cell Ranking Tasks
15 Oct 2012 | Teaching Materials | Contributor(s): Tanya Faltens
This set of ranking tasks is designed to help the learner work with and understand some of the features of common structures: planar densities, atomic densities, atomic packing factor and coordination numbers of different planes and unit cells. There are four pages-- be sure to click on "Additional Materials" or the "Supporting Docs" tab to find them all.

Ranking Task Warm Up -- exponentials and natural logs
07 May 2012 | Teaching Materials | Contributor(s): Tanya Faltens
Class warm up activity to be done in pairs. Students evaluate each of 8 terms and rank them from lowest to highest value. Some terms may have equal value.
I have found that this is surprisingly challenging for most of my students. Bonus points can be given to the first team to complete the task correctly. No calculators allowed!
It is a good idea to use an example ranking task such as this before assigning more difficult ranking tasks that relate to the course content. This drill …
