Defining Crystalline/Amorphous Phases of Nanoparticles through X-ray Absorption Spectroscopy and X-ray Diffraction: The Case of Nickel Phosphide

Literature Discussion

Submitted by Carrie Read Spray, Eastern Nazarene College
Categories
Description: 

This literature discussion activity is designed to highlight the use of different instrumentation and what details can be gained from each instrument.  It should also help the students review their knowledge of crystal structure, types of crystals, and amorphous solids.  The paper is from Chemistry of Materials, 2013, 25, 2394-2403 (DOI: 10.1021/cm303490y).  The paper should be given one week prior to class discussion, ideally after covering some of the instrumentation in class including X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). 

Learning Goals: 

Students should be able to:

  • apply their knowledge of crystal structure, types of crystals, and amorphous solids to scientific literature.   
  • elucidate the hypothesis of a paper.
  • gain a greater understanding of the instrumentation used to determine the structural details of nanoparticles.    
Implementation Notes: 

Currently I am scheduled to teach inorganic chemistry every other year and have not yet taught the course.  I plan to use several literature papers throughout the course to introduce students to the current literature and relate the concepts to the course material we cover. 

Time Required: 
One class period
Evaluation
Evaluation Methods: 

Written responses will be graded as well as an evalution of student participation in class discussion.

Evaluation Results: 

Evaluation results will be added after this learning object has been implemented in a course.
