Electrochemistry News Items & Facts - October 2021

Every day, we all use battery powered devices at home, drive vehicles, eat packaged foods, and drink clean water. These are a few examples of the countless aspects of our modern lifestyles reliant on electrochemistry - broadly defined as defined as the study of how electricity interact with materials.

As an electrochemistry instrumentation company, Admiral Instruments proudly serves our customers who are among the millions of scientists, engineers, & technicians around the world using potentiostats to uncover new ways to harness the benefits of electrochemistry for us all.

To celebrate the countless ways electrochemistry touches our lives and influences future technologies, every month Admiral Instruments posts five notable news articles, publications, & trivia about electrochemistry and related scientific disciplines.

1. Three-phase AC power is created by the magnetic induction on 3 wires spaced 120 degrees apart on a circle, which is why transmission lines have pylons in multiples of 3.

2. A study from the University of Toronto calculated that manufacturing a Tesla Model 3 emits 65% more greenhouse gases than a Toyota RAV4, but the total greenhouse gas emissions of the Model 3 break even compared to the RAV4 after 20,600 miles driven (assuming an average mix of today's grid energy source mix).

3. In 2018, global copper usage was 28 million tons and there is an estimated 5 billion tons of copper accessible within the entire planet.

4. Bioelectrical Impedance Analysis uses one or more AC signals applied to the human body to measure body fat percentage. The typical measurement setup is a 4-electrode configuration (2 hands, 2 feet).

5. The "skin effect" is a phenomenon where the current density in a conductor increases towards the conductor's surface. This effect is negligible if the frequency is less than the 50Hz and/or the diameter of the conductor is less than 1 cm.
