Crystal Field Theory and Gems--Guided Inquiry

Submitted by Adam Johnson / Harvey Mudd College on Sat, 05/14/2016 - 21:42
Description

The colors of transition metal compounds are highly variable. Aqueous solutions of nickel are green, of copper are blue, and of vanadium can range from yellow to blue to green to violet. What is the origin of these colors? A simple geometrical model known as crystal field theory can be used to differentiate the 5 d orbitals in energy. When an electron in a low-lying orbital interacts with visible light, the electron can be promoted to a higher-lying orbital with the absorption of a photon. Our brains perceive this as color.

ColourLex - a colorful website!

Submitted by Vanessa / Albion College on Tue, 03/15/2016 - 13:49
Description

ColourLex (colourlex.com) is an amazing website that mixes chemistry and art. The creators of this website have extensively catalogued paintings and the pigments that were used to create them. The pigments range from artificial to natural and organic to inorganic. You can search for the specific combination that you want to see.

Annotated List of Metal-Containing Structures in the Cambridge Structural Database Teaching Subset

Submitted by Anthony L. Fernandez / Merrimack College on Sat, 08/15/2015 - 00:46
Description

The Cambridge Crystallographic Data Centre (CCDC) provides many free programs that can be used to view and manipulate crystal structures. Additionally, they have made a subset of the Cambridge Structural Database (CSD) available for teaching purposes and many educational activities have been created to go along with this teaching subset (see link below). This teaching subset can be freely viewed through the WebCSD interface or can be used in the freely-available Mercury program. (Mercury is avaliable for Mac, Windows, and Linux systems.)

Interpreting XPS and CV data from an Electrocatalysis Publication

Submitted by Karen McFarlane Holman / Willamette University on Thu, 07/02/2015 - 20:32
Description

This is a learning object focused on analyzing a specific figure from a research article that show XPS and CV data on Ni(OH)2/NiOOH thin films that have incorporated Fe.

Peer Review - How does it work?: A literature discussion with a focus on scientific communication

Submitted by Mike Norris / University of Richmond on Thu, 07/02/2015 - 20:21
Description

This learning object is based on discussion of the literature, but it follows a paper through the peer review process.  Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots.  There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.

PVEducation.org: A resource for teaching solid-state chemistry and photovoltaics

Submitted by Kate Plass / Franklin & Marshall College on Tue, 06/30/2015 - 13:49
Description

This is a website that teaches students about various aspects of pn-junction photovoltaics, from basics about solar illumination, to solid state chemistry, to PV module design. There are numerous animations demonstrating facets of solid-state chemistry and light absorption. Here I will describe how I have used sections 3.1 Basics and 3.2 Generation in Inorganic Chemistry in the context of a specific laboratory application, but the site could have many more uses.

Copper Oxide Crystal Growth

Submitted by Ellen Steinmiller / University of Dallas on Mon, 06/29/2015 - 14:49
Description

Students in a 2nd year inorganic class read an article describing the effect of additives on the final morphology of copper oxide. (Siegfried, M.J., and Choi, K-S, “Elucidating the Effect of Additives on the Growth and Stability of Cu2O Surfaces via Shape Transformation of Pre-Grown Crystals”J. Am. Chem. Soc., 2006, 128 (32), pp 10356–10357.  dx.doi.org/10.1021/ja063574y).

Introduction to Miller Indices

Submitted by Vanessa / Albion College on Mon, 06/29/2015 - 14:22
Description

Towards the end of the semester, when we were starting to read more of the primary literature, I realized that the Miller Indices were present in most of the papers that I wanted to discuss. However, I couldn't find any good resources in textbooks that would help to explain what these were. I found this online resource through the University of Cambridge that is engaging, interactive and concise.

Materials Project

Submitted by Barbara Reisner / James Madison University on Fri, 06/12/2015 - 16:58
Description

The Materials Project is part of the Materials Genome Initiative that uses high-througput computing to uncover the properties of inorganic materials.

It's possible to search for materials and their properties

It employs high-throughput computation approaches and IT to create a system that can be used to predict properties and construct phase diagrams andPourbaix diagrams.
