Properties of olefin complexes: Pt(II) vs Au(III)

Submitted by Margaret Scheuermann / Western Washington University on Sat, 06/21/2014 - 22:01
Description

This is a literature discussion based on a paper titled “Generation and Structural Characterization of a Gold(III) Alkene Complex” (Angew. Chem. Int. Ed. 2013, 52, 1660 - DOI 10.1002/anie.201209140) that reports the first crystallographically characterized Au(III) alkene complex, [(cod)AuMe2] [BArF]. The synthesis and characterization of [(cod)AuMe2] [BArF] are presented. The structural properties are compared to those of the isoelectronic species (cod)PtMe2, and to free cod.

Complexes of alkenes, alkynes, and dienes

Submitted by Margaret Scheuermann / Western Washington University on Sat, 06/21/2014 - 21:35
Description

These slides provide an outline of the significance, bonding, properties, and reactivity of metal alkene, alkyne, and diene complexes appropriate for an upper division organometallics class. Animation is used to construct qualitative MO diagrams for olefins bound to octahedral metal centers that highlight specific bonding and antibonding interactions.

The chemdraw file used to create these slides is also provided.

Student choice literature-based take home exam question

Submitted by Hilary Eppley / DePauw University on Fri, 01/24/2014 - 15:27
Description

During my junior/senior level inorganic course, we did several guided literature discussions over the course of the semester where the students read papers and answered a series of questions based on them (some from this site!).  As part of my take home final exam, I gave the students an open choice literature analysis question where they had the chance to integrate topics from the semester into their interpretation of a recent paper of their own choice from Inorganic Chemistry, this time with limited guidance.

Solar-Powered Oxidation of Water

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.
