Submitted by Anne Bentley / Lewis & Clark College on Tue, 01/07/2014 - 18:14
Description

Students in a half-credit nanomaterials chemistry course read an article describing the electrochemical deposition of BiVO4 (Kyoung-Shin Choi and Jason A. Seabold, “Efficient and Stable Photo-Oxidation of Water by a Bismuth Vanadate Photoanode Coupled with an Iron Oxyhydroxide Oxygen Evolution Catalyst” J. Am. Chem. Soc.

Brief introduction to local surface plasmons (LSPRs) for nanoparticle color

Submitted by Sarah K. St. Angelo / Dickinson College on Fri, 06/28/2013 - 09:30
Description

This is a very brief introduction to the origin of color in nanoparticle systems.  A link to a video is included in the slides that shows the addition of the reducing agent to the gold precursor solution.  The link is also available as a Web Resourse (below).

QSAR and Inorganic Chemistry

Submitted by Vanessa / Albion College on Thu, 06/27/2013 - 14:59
Description

This presentation provides a short introduction to Quantitative Structure-Activity Relationships and its use in Inorganic Chemistry. A brief introduction to Linear-Free Energy Relationships and the Hammett Equation is given, followed by three examples of how QSARs have been used in inorganic chemistry. 

A Schaaking development of colloidal hybrid nanoparticles

Submitted by Anne Bentley / Lewis & Clark College on Thu, 06/27/2013 - 10:52
Description

This literature discussion was created at the NSF-TUES sponsored workshop at Penn State, June 2013.  It is based on the article from Ray Schaak’s group (Buck, Matthew R.; Bondi, James F.; Schaak, Raymond E. “A total-synthesis framework for the construction of high-order colloidal hybrid nanoparticles” Nature Chemistry, 2012 4, 37-44, DOI: 10.1038/NCHEM.1195), which Ray presented at the workshop.

Tuning the band gap of CZT(S,Se) nanocrystals by anion substitution

Submitted by Benny Chan / The College of New Jersey on Thu, 06/27/2013 - 09:45
Description

The paper from the Prieto group, Riha, S. C.; Parkinson, B. A.; Prieto, A. L. J. Am. Chem. Soc. 2011, 133, 15272-15275, is proposed to be an excellent literature article for achieving several learning goals in the understanding of fundamental solid state and materials chemistry. The learning object was developed as a part of the 2013 VIPEr workshop and has not been tested in the classroom. We have developed a set of discussion questions that can be used as a guide for the students.

Concept mapping the primary literature: "Compositionally Tunable Cu2ZnSn(S1-x,Sex)4 nanocrystals"

Submitted by Benny Chan / The College of New Jersey on Thu, 06/27/2013 - 09:26
Description

Concept maps are a visual way to organize and represent information. In this literature discussion, we introduce a novel technique for teaching literature analysis to students where concept maps are used for establishing relationships between the key ideas, theories, procedures, and methods of a proposed literature article. Using the article “Compositionally Tunable Cu2ZnSn(S1-xSex)4 Nanocrystals: Probing the Effect of Se-Inclusion in Mixed Chalcogenide Thin Films” (Riha, S.C.; Parkinson, B.A.; Prieto, A.L. J. Am. Chem.

Synthesis and Characterization of Magnetic Spinel Nanoparticles

Submitted by Anne Bentley / Lewis & Clark College on Wed, 06/26/2013 - 22:15
Description

This learning object centers around an article published fairly early on in the history of nanoscience (Sun, et al. “Monodisperse MFe2O4 (M = Fe, Co, Mn) Nanoparticles” J. Am. Chem. Soc. 2004, 126, 273-279.

Kool-Aid analysis: Visible Spectroscopy and Paper Chromatography

Submitted by Megan Strayer / The Pennsylvania State University on Wed, 06/26/2013 - 13:55
Description

This lab experiment is designed to introduce the electromagnetic spectrum to non-science majors in a food chemistry course by using everyday food (i.e. Kool-Aid packets). Students will use a spectrophotometer to correlate wavelength to color, as well as determine the mass percent of certain colored dyes in a Kool-Aid sample. Paper chromatography is also introduced to determine the number of dyes in a Kool-Aid sample. This lab is adapted from Sigmann, S; Wheeler, D. J. Chem. Ed., 2004, 81, p. 1475.

Literature summary through student presentation - free choice of topic.

Submitted by Cameron Gren / University of North Alabama on Wed, 06/26/2013 - 07:59
Description

(1) Student choses and reads a journal article of his/her choice that is related to a topic we have discussed during the semester. (i.e. atomic structure, MO theory, group theory, solid state structure, band theory, coordination chemistry, organometallics, catalysis). Suggested journals include, but are not limited to JACS, Inorg. Chem., Organometallics, Angew. Chem., JOMC, Chem. Comm.)
