New graphene printing technology can produce electronic circuits that are low-cost, flexible, highly conductive and water repellent, researchers report.

The nanotechnology “would lend enormous value to self-cleaning wearable/washable electronics that are resistant to stains, or ice and biofilm formation,” according to the new paper.

“We’re taking low-cost, inkjet-printed graphene and tuning it with a laser to make functional materials,” says Jonathan Claussen, an assistant professor of mechanical engineering at Iowa State University, an associate of the US Department of Energy’s Ames Laboratory, and the corresponding author of the paper in the journal Nanoscale.

South Korean universities have successfully negotiated a better pricing deal from publishing giant Elsevier, according to a report from Science Magazine. This deal comes after a standoff between the consortium of hundreds of institutions and the publisher, where database access contracts were refused due to exorbitant price increases.

Earlier this month as Elsevier threated to cut access to ScienceDirect, a database containing content from over 3,500 academic journals, the two parties came to an agreement of a subscription price hike of between 3.5 and 3.9 percent, instead of the initial 4.5 percent as pushed by Elsevier.

“We want Elsevier to abolish the minimum flat rate system, in which our universities have to pay for digital content that nobody reads,” Lee Chang Won, secretary general of the Korea University & College Library Association, told Science Magazine.

South Korea’s pushback against Elsevier follows the trend of many similar efforts still underway in Germany, including Projekt DEAL. While over 200 German institutions have already canceled their Elsevier subscriptions in protest of skyrocketing prices, the publisher has still not terminated access, looking to continue negations.

Editor’s note: On Jan. 22, 2018, the Trump administration announced plans to impose punitive duties on solar panels imported from abroad. This decision came in response to a complaint filed by two solar companies, but much of the industry opposes the action, which trade groups say will increase the cost of solar projects and depress demand. To illustrate what’s at stake, energy scholar Joshua Rhodes provides some context on the U.S. solar industry and its opportunities and challenges.

How big is the U.S. solar industry, and what is its growth trajectory?

The U.S. solar industry generated US$154 billion in economic activity in 2016, including direct sales, wages, salaries, benefits, taxes and fees. Its revenues have grown from $42 million in 2007 to $210 million in 2017.

About 25 percent of total new power plant capacity installed in 2017 came from solar. Total installed U.S. solar capacity is over 50 gigawatts – the equivalent generating capacity of 50 commercial nuclear reactors.

Researchers have found a way to get electrons to travel much farther than was previously thought possible in materials for organic solar cells. This advance could make these solar cells much more useful than inorganic alternatives.

“For years, people had treated the poor conductivity of organics as an unavoidable fact, and this shows that that’s not always the case,” says research leader Stephen Forrest, professor of engineering at University of Michigan.

Peter Mascher is a professor in the Department of Engineering Physics and holds the William Sinclair Chair in Optoelectronics at McMaster University in Ontario, Canada. There, he leads a research group specializing in the fabrication and characterization of nanostructures. Mascher was recently named technical editor of the ECS Journal of Solid State Science and Technology (JSS) in the area of dielectric science and materials.

The Electrochemical Society: What made you want to take on an ECS editorial role?

Peter Mascher: I’ve been a member of the ECS Dielectric Science and Technology Division for many years and we’ve had many discussion on how to raise the quality of submissions to JSS and by extension, the quality of the journal overall. At some point in time, when the opportunity arises, one should try to make a contribution rather than just discussing it. I think there are avenues toward increasing the profile of the journal and I hope I can make a contribution there.

ECS: What do you hope to accomplish in your new role as JSS technical editor?

PM: I would like my colleagues who contribute to the ECS meetings in the various symposia to be much more aware of the journal and the opportunity to publish in JSS, which will help increase the overall quality. There should be a strong connection between the excellent presentations that are given at the various symposia at ECS meetings and the manuscripts that are being submitted to the journal.

To date, the ECS Digital Library contains over 40 completed focus issues across the Journal of The Electrochemical Society and the ECS Journal of Solid State Science and Technology.

All of these issues, devised to highlight rapidly accelerating areas of scientific and technological interest, continue to attract significant attention from ECS’s readership.

During 2017, the average ECS focus issue received 12,495 full text downloads.

One particular focus issue of 2017, however, proved no average issue, acquiring nearly 9.5 times that amount.

The JES Focus Issue of Selected Papers from IMLB 2016 with Invited Papers Celebrating 25 Years of Lithium Ion Batteries amassed a whopping 119,465 full text downloads over the course of 2017, securing its place not only as the most read focus issue of the year, but also as the most read focus issue in ECS history.

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.
