Description: 

This literature discussion is based off a Nature article by Buck, Bondi, and Schaak (Buck, M.; Bondi, J.; Schaak, R. Nat Chem 2012, 4, (1), 37-44 DOI: 10.1038/NCHEM.1195).  It spans topics of solid state, crystallography, characterization techniques, and comparing inorganic to organic synthesis.

Learning Goals: 

Overarching Learning Goals

Students will be able to,

  • Develop an awareness of cutting edge research in inorganic chemistry (could include in introduction to LO)
  • Transfer previous knowledge to cutting edge research
  • Develop critical reading skills for the technical literature
  • Recognize the importance of primary literature for ongoing education

Learning Goals for Individual Problems

Students will be able to:

  • Understand the unique properties of hybrid nanoparticles within the context of the larger field.
  • Identify the conceptual synthetic strategies common to the construction of complex materials and large organic molecules.
  • Demonstrate knowledge of simple solid-state structures (cubic close packed), and distinguish features of intermetallic versus alloyed binary metals.
  • Compare a fundamental step in nanoparticle synthesis to fundamental steps in molecular redox and acid base chemistry.
  • Select an appropriate characterization technique for heterometallic nanoparticles and accurately describe a prospective characterization
  • Calculate lattice mismatch and evaluate the percent of mismatch which allows a compound to form.
  • Organize and classify TEM and XRD techniques (used in the referenced paper) for the types of information the techniques can provide. Explore the limitations of using only one technique

Implementation Notes: 

The students will be given the article and the discussion questions for homework with a week to complete both.  When the paper is discussed in class, the students can work in groups to discuss the paper and their answers to the questions.

Time Required: 
One class period
Web Resources: 
Buck, et al. Nat Chem, 2012, 4, 37-44
Evaluation
Evaluation Methods: 

The students can be graded on their answers to the questions after discussing in class.
