The deadline for submission to the Journal of The Electrochemical Society Focus Issue on The Brain and Electrochemistry has been extended to April 30, 2018.

The focus issue will provide a forum for the discussion of research and developments on how the central and peripheral nervous systems can be viewed and studied in terms of electrical circuits and electrochemical sensors, reactions, and methods.

The issue is dedicated to R. Mark Wightman (University of North Carolina at Chapel Hill) and Christian Amatore (Ecole Normale Supérieure), two individuals who devoted their careers to study of these topics, training and influencing countless researchers over the years.

Electrochemistry and Data Science

Data science is often hailed as the fourth paradigm of science. As the computing power available to researchers increases, data science techniques become more and more relevant to a larger group of scientists. A quick literature search for electrochemistry and data science will reveal a startling lack of analysis done on the data science side. This paper is an attempt to help introduce the topics of data science to electrochemists, as well as to analyze the power of these methods when combined with physics-based models.

At the core of the paper is the idea that one cannot be successful treating every problem as a black box and applying liberal use of data science – in other words, despite its growing popularity, it is not a panacea. The image shows the basic workflow for using data science techniques – the creation of a dataset, splitting into training-test pairs, training a model, and then evaluating the model on some task. In this case, the training data comes from many simulations of the pseudo two-dimensional lithium-ion battery model. However, in order to get the best results, one cannot simply pair the inputs and outputs and train a machine learning model on it. The inputs, or features, must be engineered to better highlight changes in your output data, and sometimes the problem needs to be totally restructured in order to be successful.

A team of researchers from MIT recently demonstrated a new electrochemical method to study thermodynamic processes in an ultra-high temperature molten oxide. In an effort to find new insights into the thermodynamic properties of refractory materials, researchers have developed a container-less electrochemical method to study thermodynamic properties of materials like aluminum oxide, which melts at temperatures above 2,000 degrees Celsius.

The finding were reported in the open access paper, “Electrochemical Study of a Pendant Molten Alumina Droplet and Its Application for Thermodynamic Property Measurements of Al-Ir,” which was recently published in the Journal of The Electrochemical Society.

“We have a new technique which demonstrates that the rules of electrochemistry are followed for these refractory melts,” says senior author Antoine Allanore, an associate professor of metallurgy and member of ECS. “We have now evidence that these melts are very stable at high temperature, they have high conductivity.”

From Wastewater to Fertilizer

The National Science Foundation is spearheading a $2.4 million research initiative to develop new methods to create commercial fertilizer out of wastewater nutrients. Among the researchers working on this project, ECS member and chair of the Society’s Energy Technology Divison, Andrew Herring, is leading an electrochemical engineering team in electrode design, water chemistry, electrochemical operations, and developing a bench-scale electrochemical reactor design.

The goal of this project is to take the nitrogen and phosphorus that exists in wastewater and transform it into fertilizer struvite, which is made up of magnesium, ammonium, and phosphate.

“Basically, you’d have a hog barn and you’d collect the liquid effluent from the farm and run it through a reactor and you’d get a solid fertilizer out of the back and, hopefully, energy,” Herring, Colorado School of Mines professor, says in a statement. “At the end of the day, we hope to optimize this thing so it makes energy, saves water, and produces fertilizer for food production.”

This work is is a collaborative effort with ECS members Lauren Greenlee, lead princial investigator and Assistant Professor at the University of Arkansas; and Julie Renner, Assistant Professor at Case Western Reserve University.

This isn’t Herring’s first foray into water and energy research. During the PRiME 2016 meeting, Herring co-organized the Energy/Water Nexus: Power from Saline Solutions symposium.

Scientists can now directly probe hard-to-see layers of chemistry due to the development of an X-ray toolkit out of Lawrence Berkeley National Laboratory.

The research team behind the initiative believes that their development could provide insight about battery performance and corrosion. Additionally, it could give insight into a variety of chemical reactions, including biological and environmental processes.

The from LBNL:

In a first-of-its-kind experiment at Berkeley Lab’s Advanced Light Source, an X-ray source known as a synchrotron, researchers demonstrated this new, direct way to study the inner workings of an activity center in chemistry known as an “electrochemical double layer” that forms where liquids meets solids—where battery fluid (the electrolyte) meets an electrode, for example (batteries have two electrodes: an anode and a cathode).

Read the full article.

In a battery, changes in electrical potential can be seen in the electrochemical double layer.
