Introduction to Pulsed Gradient Spin Echo DOSY

Submitted by Jacob Lutter / University of Southern Indiana on Thu, 02/08/2018 - 14:35
Description

Pulsed Gradient Spin Echo (PGSE) DOSY is a NMR technique used for determining the hydrodynamic radius of a molecule in solution by measuring the rate of diffusion. This technique requires a standard, usually tetrakis(trimethylsilyl)silane (TMSS). This activity will cover the basics of how PGSE works and includes built in animations to demonstrate how the nuclear magnetization is affected. Each slide has comments explaining the content for the user's convenience.

Inorganic Chemistry II

Submitted by Chip Nataro / Lafayette College on Mon, 01/15/2018 - 14:03
Description

This course uses molecular orbital theory to explain the electronic structure and reactivity of inorganic complexes. Topics include symmetry and its applications to bonding and spectroscopy, electronic spectroscopy of transition-metal complexes, mechanisms of substitution and redox processes, organometallic and multinuclear NMR.

 

Additional notes

I do not require a formal text but George Stanley's organometallic chemistry 'book' on VIPEr is made available to students (the link is found below).

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.
