Cyclic voltammetry
This is a short presentation on cyclic voltammetry. It is covers the basics and some simple electrode mechanisms. There is room for improvement (especially in my art) and suggestions are welcome.

Early in 2009, Christopher Cummins’ group at MIT reported (in Science) the synthesis of AsP3, a compound that had never been isolated at room temperature. Later that year, a full article was published in JACS comparing the properties and reactivity of AsP3 to those of its molecular cousins, P4 and As4. The longer article is full of possibilities for discussion in inorganic chemistry courses, with topics including periodic trends, NMR, vibrational spectroscopy, electrochemistry, molecular orbital theory, and coordination chemistry.
Every time I teach inorganic, I always ask myself the question: “What’s the best way to motivate the course and get the students excited?” A long time ago, I decided it’s important to start with some music. (Until last year, Tom Lehrer’s The Elements was my favorite. As a TMBG fan, I’ve swiched to Meet the Elements.)
In the two years since this article was published, it has jump-started a large amount of research in the area of cobalt-based catalysts for solar water splitting. The paper describes the electrochemical synthesis and oxygen-evolution capabilities of a Co-phosphate catalyst under very mild conditions. The paper can stimulate discussion of many topics found in the inorganic curriculum, including electrochemistry, semiconductor chemistry, transition metal ion complex kinetic trends, and solid state and electrochemical characterization techniques.

In this laboratory experiment, students construct a solar cell from a combination of synthetic and natural materials. It touches on a variety of chemical principles (kinetics, photochemistry, electrochemistry, intermolecular forces, material properties); however, the primary aim is the experience of turning materials into components and then assembling them into a working device. This experiment is unique in that it emphasizes each material's function, and how its properties affect this function. Students can seal these solar cells and take them home afterward.
This book was originally written (full disclosure: I am one of the co-authors) for college teachers as a resource text to encourage and support the incorporation of more solid state and materials chemistry into the general chemistry curriculum. The Companion, as I refer to it, is filled with background material, demonstrations, laboratory experiments, and end-of-chapter problems that will aid the non-specialist in enriching their teaching with examples from the world of solid state materials. Although intended for a general chemistry audience, several of the chapters present fairly sophis
This presentation provides a brief overview of the contributions of five AfricanAmerican chemists, including two inorganic chemists. George Washington Carver is quite often themost celebrated African American chemist (soil chemist), but he is only one individual! There are many other African Americans that have made important and significant contributions to the chemical sciences. The profiles include inorganic chemists, namely, Professor Gregory H. Robinson, University of Georgia and Dr. Novella Bridges, Pacific Northwest National Laboratory (PNNL).
