Description

This lab handout and supplementary materials were developed based on a publication in the Journal of Chemical Education:

Berger, P.; Adelman, N.; Beckman, K.; Campbell, D.; Ellis, A.; Lisensky, G. Preparation and Properties of an Aqueous Ferrofluid. J. Chem. Educ. 1999, 76 (7), 943-48

Luminescence

Submitted by Vivian / Clemson University, Department of Chemistry on Thu, 08/14/2014 - 22:53
Description

This is a 5-slides on luminescence. It contains introductory and basic description of different examples of luminscence. Since, this is a community of inorganic chemists, only inorganic compounds are discussed as examples.

The Chemistry of Cooley's Anemia: A Case Study

Submitted by Chris Bailey / Wells College on Wed, 08/06/2014 - 11:36
Description

In this case study, information is presented to students in the form of a dialog between a physician and two parents who have just learned that their child has thalassemia (Cooley’s Anemia). The treatment for this disorder requires a lifetime commitment to whole blood transfusion and chelation therapy (both administered on a daily to weekly basis); the biggest obstacle to long term survival is patient non-compliance.

Isn't It Ionic (with apologies to Alanis Morissette)

Submitted by Craig M. Davis / Xavier University on Sun, 08/03/2014 - 16:58
Description

This spoof of the song "Isn't It Ironic" (by Alanis Morissette) summarizes the properties of ionic compounds in verse. Suitable for General Chemistry classes as well as Inorganic Chemistry, although a reference is made to the Born-Meyer equation.

C&E News as a Starting Point for Bioinorganic Literature Discussions

Submitted by Chris Bailey / Wells College on Mon, 07/28/2014 - 15:37
Description

This learning object consists of a bibliography of materials concerning bioinorganic chemistry which have appeared in C&E News over approximately the past 15 years (1999-2014). Many come from the Science and Technology Concentrates, some from News of the Week, others are full articles, and a few are letters to the editor. They cover a wide variety of bioinorganic topics. Also included are citations for the articles from the primary literature paper referred to in the respective C&E News articles.

The Structure and Function of Transferrin

Submitted by Chris Bailey / Wells College on Tue, 07/22/2014 - 14:51
Description

These Five Slides About examine the structure and function of the iron binding and transport protein transferrin. Students learn that transferrin also acts as an iron buffer and as a potential antimicrobial agent. The structure of the protein is explored in detail; it consists of a single polypeptide (80kDa) folded into two lobes, each of which can bind a single iron in a high affinity region. Changes in the protein as a result of iron uptake is discussed. The iron binding region and the requirement of a bidentate synergistic anion (carbonate) are examined.

An Accounting Ledger Method for Determining Lewis Dot Structures

Submitted by Chris Bailey / Wells College on Sat, 07/19/2014 - 19:45
Description

Over several decades of teaching General Chemistry I have utilized various methods to get students to draw appropriate Lewis Dot Structures. About 10 years ago I learned about a process which I call the "Account Ledger Method". In this method all valence electrons are assumed to initially belong to the molecule (and placed in a ledger) and not to specific individual atoms. As the molecule is put together those electrons are distributed systematically and removed from the ledger.

The "Zinc Spark" - Zinc as a signaling chemical in life

Submitted by Kyle Grice / DePaul University on Sat, 07/19/2014 - 11:11
Description

This web resource is a TEDx talk about zinc and zinc's role in the early stages of the maturation of the egg. This would be a great introduction video for a gen chem, inorganic, or bioinorganic chemistry course. It introduces the idea that Zinc is stored in specific locations on the egg and then released all at the same time.

Employing 2D NMR and NOE to assign protons in an organometallic complex

Submitted by Sherzod / Northwestern University on Thu, 07/17/2014 - 20:58
Description

The following paper will be given to the students to study at home along with the questions in the attached document. Students will be allowed to discuss their answers in small groups and refine their answers, before the corresct answer is revealed.

The students will not need to see the actual spectra that are in the SI to be able to address the given questions, the spectra can be projected to the class when the answers of the student groups are discussed

Origins of Enantioselectivity during Allylic Substitution Reactions Catalyzed by Metallacyclic Iridium Complexes.

Having fun with your own molecular models

Submitted by Arpita Saha / Georgia Southern University on Wed, 07/16/2014 - 15:04
Description

This is a fun chemistry project where students make model compounds to learn various structural aspects of the compound. This is an individual project that is each student is assigned with one compound.  They can use any item (for e.g. Styrofoam balls etc) to make their very own model compound. The model should contain all the atoms (visually distinctive), bonds, lone pairs. Student is expected to create something novel rather using molecular model kit. They can use text book and lecture material for the resources.
