Green Chemistry seminar videos

Green Chemistry

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!

This activity was supported by an ACS Sustainability Grant awarded to the Portland Section of the American Chemical Society. Videos recorded by Joseph Thiebes.

Diamond Lattice Structure Pendant

The diamond lattice structure pendant by Joseph Thiebes, 2015.

Diamonds are a scam! They are very common, and rather 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.

Want to know more? Check out the video, and the beautiful jewelry from Iturraldediamonds.com, below:

Diamonds are a scam, and 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 and best survival knife. Shown below is the default material, blackened steel, giving the traditional appearance of carbon atom models.

The piece is about 1.5 inches across. Just loop your favorite chain through the open lattice and put it on. Science jewelry!

GMO Labeling

Joseph Thiebes eaten by Insecta-Cobbfish

Here's my story on GMO labeling for the Portland State Vanguard.  I wanted to use more from all my interviewees -- but that's the way it goes. I wish I could do a whole documentary! But I had to keep the focus tight and I wanted to get people to see that it's a complex and human issue. That wasn't easy but I think I gave people some food for thought, if not an in depth view. 

The video attached to the article is also a big step up in my production quality.

GMO crops improve incomes and reduce environmental impacts

biotechnology and agriculture

In spite of the repeated claims by activists who oppose biotechnology and GMOs on ideological grounds, GM traits are improving environmental impacts from pesticide (insecticide and herbicide) use. Genetically modified foods have been available in the marketplace since 1996, and in the last 2 decades, pesticide use in the areas where GM crops are planted has been reduced by 503 million kg, and the environmental impact dropped by 18.7%. Here's more from the press release, where you can find a link to the full document:
