2019 Nobel Prize - Li-ion battery LOs

Submitted by Barbara Reisner / James Madison University on Wed, 10/09/2019 - 20:28

Congratulations to the 2019 recipients of the Nobel Prize - John B. Goodenough, M. Stan Whittingham and Akira Yoshino. It's a well deserved honor!

There are several LOs on VIPEr that talk about lithium ion batteries and related systems. The 2019 Nobel is a great opportunity to include something about these batteries in your class.

I hope to see more LOs in the coming weeks so we can bring this chemistry into our classrooms!

Porphyrin-Based Metal-Organic Frameworks

Submitted by Amanda Bowman / Colorado College on Thu, 06/27/2019 - 15:29
Description

This literature discussion explores the physical structures, electronic structures, and spectroscopic characterization of several porphyrin-based metal-organic frameworks through discussion of “Iron and Porphyrin Metal−Organic Frameworks: Insight into Structural Diversity, Stability, and Porosity,” Fateeva et al. Cryst. Growth Des. 2015, 15, 1819-1826, http://dx.doi.org/doi:10.1021/cg501855k.

Crystallographic Resources at Otterbein University

Submitted by Kevin Hoke / Berry College on Sat, 06/08/2019 - 22:44
Description

This site is another excellent resource from Dean Johnston (see also his Symmetry resource).

Important Note: Part of this web resource has recently been replaced by a new site with a new URL. The previous version used JSmol and had some quirks with ion sizes, but this complete revision addresses those and has a much more robust "tutorial" style for students to work through solid state structural types.

VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sat, 06/08/2019 - 16:41

During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

Hyperphysics

Description

The hyperphysics website uses concept maps as a way to organize physics content knowledge: http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html (condensed matter). I cam across this website while doing a review of the literature on what students know about semiconductors. There are nice explanations of many of the topics associated with semiconductors and they are organized in an unique way.

Venn Diagram activity- What is inorganic Chemistry?

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 01/03/2019 - 18:02
Description

This Learning Object came to being sort of (In-)organically on the first day of my sophomore level intro to inorganic course. As I always do, I started the course with the IC Top 10 First Day Activity. (https://www.ionicviper.org/classactivity/ic-top-10-first-day-activity).  One of the pieces of that In class activity asks students- novices at Inorganic Chemistry- to sort the articles from the Most Read Articles from Inorganic Chemistry into bins of the various subdisciplines of Inorganic Chemistry.

Developing methodology to evaluate nanotoxicology: Use of density.

Submitted by Tori Forbes / University of Iowa on Fri, 06/15/2018 - 17:30
Description

This activity is designed to relate solid-state structures to the density of materials and then provide a real world example where density is used to design a new method to explore nanotoxicity in human health.  Students can learn how to calculate the density of different materials (gold, cerium oxide, and zinc oxide) using basic principles of solid state chemistry and then compare it to the centrifugation method that was developed to evaluate nanoparticle dose rate and agglomeration in solution.

 

Redox Chemistry of a Potential Solid State Battery Cathode – Discuss!

Submitted by Sabrina Sobel / Hofstra University on Mon, 08/07/2017 - 14:01
Description

Lithium battery technology is an evolving field as commercial requirements for storage and use of energy demand smaller, safer, more efficient and longer-lasting batteries. Copper ferrite, CuFe2O4, is a promising candidate for application as a high energy electrode material in lithium based batteries. Mechanistic insight on the electrochemical reduction and oxidation processes was gained through the first X-ray absorption spectroscopic study of lithiation and delithiation of CuFe2O4.
