The terms “anode” and “cathode” were first published by Michael Faraday, F.R.S. in 1834. A delightful (and highly recommended) historical account of how these words were conceived by Faraday and his associates can be found in Faraday Consults the Scholars: The Origins of the Terms of Electrochemistry by Sydney Ross . As scientists have learned about how electrochemistry works, the definitions have evolved somewhat. The following is a brief summary of their etymology and their meaning as it stands today in electrochemical circuits. In the course of my own study of electrochemistry, I thought other students may find this information helpful in keeping everything straight.
Should quantum physics e’er be standardized,
when taken in a thought experiment,
its terms of meaning judged and analyzed,
absurdity prevails, not merriment.
A cat both dead and living cannot be.
That was the point old Erwin tried to make.
To measure is to interfere, you see,
some photon must be thrown to cause a quake.
Awareness cannot of itself crash waves;
By heat and light, the box became a grave.

I’m a co-author of the following article, published in two parts in the China Coatings Journal:
I’m a co-author of a newly published conference paper entitled “Diatom Frustules as Substrates for Photocatalysts” in TechConnect Briefs 2018 vol. 2: Materials for Energy, Efficiency and Sustainability.
One of my photographs was featured in this April 12, 2018 article in NASA’s Astrobiology Magazine: “Are viruses the new frontier for astrobiology?”
The photo originally appeared in the Portland State Vanguard, in this short article and interview with accompanying photos and video about the research of Prof. Ken Stedman.
Join the Portland, Oregon section of the American Chemical Society for a couple of wonderful talks on Green Chemistry.
First, Dr. David Stuart, Assistant Professor of Chemistry at Portland State University, offers a brief introduction to Green Chemistry and an example from his lab.
Next, Dr. Tom Wilson, retired Director of Materials Technology at Nike, offers an interesting look at the Green Chemistry of rubber in a story about zinc oxide in Nike’s Environmentally Preferred Rubber.
Take a look at the two videos below!
The Portland section of the American Chemical Society interviewed me about my internship at NASA Glenn Research Center in Cleveland, Ohio in summer, 2015, where I worked on lithium-sulfur battery research.

Diamonds are a scam! They are common and worthless. One company has cornered the market, controlling how many diamonds are mined and how they reach the consumer. Mining for diamonds is back-breaking work, and the wages are ridiculously low.
It is for this reason I have created the diamond lattice structure pendant. This pendant features the structure of diamonds, formed by carbon atoms in a specific arrangement.
Pick from a variety of materials, including everything from solid gold to white plastic. Shown here is the default material, blackened steel, giving the traditional appearance of carbon atom models.
“I would never call myself a chemist,” said Nobel Prize in Chemistry 2014 recipient Eric Betzig.
Betzig was the 2015 speaker at the annual Mark Gurevitch Memorial Lecture Series, hosted by the Physics Department at Portland State University. During his lecture at Hoffman Hall on May 14, Betzig spoke about his career and his prize-winning work. Read more about Betzig’s talk in this article by Joseph Thiebes, and in the video below.
