Here is a nice refresher on VSEPR Theory
The Royal Society of Chemistry has produced podcasts for every element! Enjoy brief stories about the elements that place them in historical context.
The magazine Chemical & Engineering News recently ran a feature article on the rapidly changing gemstone market and the role that synthetic diamonds and other gemstones are playing.
Researchers at Harvard have provided the first experimental demonstration of solid metallic hydrogen. At very high pressures, dihydrogen (H2) is converted to a solid with the properties of an atomic metal, including being reflective.

More than 100 years ago, Alfred Werner first proposed the structure of coordination complexes in the mode that we still use today! The following papers discuss some of Werner’s many accomplishments and contributions to the field of transition metal complexes.
- Werner’s intuition on coordination chemistry and current-day characterization on samples prepared by Werner and his lab are discussed in this report.
- In this paper, a brief history on coordination chemistry from the 19th Century and Werner’s proposed structures are presented.
- Crystallographic characterization of an original crystal prepared by Werner and his lab is shown here.
This paper covers ways to identify synthesized gemstones and includes detailed images illustrating defects in synthesized gemstones.
This paper discusses different types of gemstones as well as methods utilized in synthesizing gemstones.
