Dissecting Catalysts for Artificial Photosynthesis

Submitted by Anne Bentley / Lewis & Clark College on Mon, 07/07/2014 - 13:57
Description

Anne asked the students in her junior/senior inorganic course to develop their own literature discussion learning objects and lead the rest of the class in a discussion of their article.  Each student chose one article from a list of suggestions provided.  Student Hayley Johnston chose this article describing a Mn-containing catalyst for carbon dioxide reduction (Jonathan M. Smieja, Matthew D. Sampson, Kyle A. Grice, Eric E. Benson, Jesse D. Froehlich, and Clifford P.

Learning Objects used at the 2014 VIPEr Workshop on Bioinorganic Chemistry

Submitted by Betsy Jamieson / Smith College on Wed, 06/25/2014 - 09:32

This collection highlights the learning objects used at the 2014 VIPEr workshop on the Bioinorganic Applications of Coordination Chemistry to introduce participants to the field of bioinorganic chemistry.   They provide essential background information on how metals bind to proteins as well as the techniques used in the research papers presented at the workshop.  A list of learning objects created at the workshop based on the current research of our expert speakers can be found at: 

First use of the term "bioinorganic"

Submitted by Joshua Telser / Roosevelt University on Wed, 03/19/2014 - 20:19
Description

Thanks to information first provided to me by Prof. Brian M. Hoffman, Northwestern University, I believe that the first documented use of the term "bioinorganic chemistry" occurred at a meeting held at Virginia Tech (VPI&SU) in June, 1970. This meeting was jointly organized with Canadian researchers and was thus an international meeting.

This meeting resulted in an Advances in Chemistry Series book, which has the following URL:

Water Oxidation Catalyzed by NHC Complexes of Iridium

Submitted by Peter M Graham / Saint Joseph's University on Wed, 02/19/2014 - 12:08
Description

A literature discussion based on an interesting paper from Bernhard and Albrecht about a catalytic water oxidation promoted by irdium complexes featuring abnormal/mesoionic NHC ligands.

I used this in an upper-level Organometallics course after discussing NHC ligands in class.

 

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.

Electronic Absorption Spectroscopy of Aquated Transition Metal Ions

Submitted by Zachary Tonzetich / University of Texas at San Antonio on Thu, 01/23/2014 - 12:07
Description

I developed this laboratory experiment for our instrumental analysis class. The course is taken by junior and senior chemistry majors, who for the most part have had one inorganic chemistry course and some physical chemistry. The laboratory is operationally very simple and has students record the UV-vis spectra of transition metal sulfate salts in water using volumetric technique. They record the molar absorptivities for each peak and use this data to determine the number of waters of hydration for each salt by comparing with literature absorptivity values.

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.

Synthesis and Migratory-Insertion Reactivity of CpMo(CO)3(CH3): Small-Scale Organometallic Preparations Utilizing Modern Glove-Box Techniques

Submitted by Matt Whited / Carleton College on Mon, 08/26/2013 - 14:22
Description

This laboratory experiment spans three weeks and introduces advanced undergraduates to modern small-scale synthesis techniques involving an inert-atmosphere glove box.  The robust syntheses transform [CpMo(CO3]2 into the methylated CpMo(CO)3(CH3) and examine the phosphine-induced migratory insertion to form various Cp-supported Mo(II) acetyl complexes.  At each step in the synthesis, a combination of IR and multinuclear (1H, 13C, and 31P) NMR spectroscopies allow students to assess the purity of their products and

Five Slides about X-ray Photoelectron Spectroscopy (XPS)

Submitted by Sophia E. Hayes / Washington University on Fri, 06/28/2013 - 09:35
Description

This is a short presentation giving an overview of x-ray photoelectron spectroscopy (XPS), meant to be an introduction for those who are unfamiliar with the technique.

Introduction to Synchrotron Radiation

Submitted by Megan Strayer / The Pennsylvania State University on Thu, 06/27/2013 - 15:35
Description

This 5 slides about gives a basic introduction to synchrotron radiation.  Information includes how the particles are accelerated, how they travel to the individual instruments, and where synchrotrons in the USA are located.
