Q&A series with ECS OpenCon 2017 speakers

Meredith Morovati

Meredith Morovati, executive director of Dryad

ECS will be hosting its first ever OpenCon event on October 1 in National Harbor, MD. OpenCon will be ECS’s first, large community event aimed at creating a culture of change in how research is designed, shared, discussed, and disseminated, with the ultimate goal of making scientific progress faster.

During ECS’s OpenCon, Meredith Morovati, executive director of Dryad, will give a talk on open data.

The following conversation is part of a series with speakers from the upcoming ECS OpenCon. Read the rest of the series.

ECS: How and why did Dryad get its start; and how has it grown since then?

Meredith Morovati: Editors from journals in the fields of evolution and life science—some of them competing journals—were becoming concerned that it was difficult to find data that supported the literature; the “policy” of asking an author to share data after the fact was a failure. In 2011, twelve of these editors came together to remedy this, and developed the Joint Data Archive Policy (JDAP). JDAP required, as a condition of publication, that data be archived in an appropriate public archive and stated that data are products of the scientific enterprise in their own right. These editors argued that data must be preserved and usable in the future. JDAP is now a model for requiring data as a condition of publishing an article.

The use of Dryad was not stipulated as part of this policy, but Dryad became the preferred solution due to its one-to-one relationship with data and scholarly literature. In addition, Dryad curates data to ensure high quality metadata and is committed to discoverability.

Chemical engineers have generated ultra-pure green light for the first time.

The new light-emitting diode paves the way for visibly improved color quality in a new generation of ultra-high definition displays for TVs and smartphones.

Electronic devices must first be able to produce ultra-pure red, blue, and green light in order to enable the next generation of displays to show images that are clearer, sharper, richer in detail, and with a more refined range of colors. For the most part, this is already possible for red and blue light; green light, however, has been at the limits of technology.

This is due mainly to human perception, since the eye is able to distinguish between more intermediary green hues than red or blue ones. “This makes the technical production of ultra-pure green very complex, which creates challenges for us when it comes to developing technology and materials,” says Sudhir Kumar of ETH Zurich, co-lead author of the study.

Ultra-pure green plays a key role in extending the color range, or gamut. Ultimately, new hues arise from the technical mixture of three base colors: red, blue, and green. The purer the base colors, the broader the range of hues a screen can display. The new LED is in line with 97 to 99 percent of the international standard for Ultra HD, Rec.2020. By comparison, the purest color TV displays currently available on the market cover on average only 73.11 to 77.72 percent; none exceeds 80 percent.

InterfaceAs vice chair of the Industrial Electrochemistry and Electrochemical Engineering Division, it is with great pleasure that I introduce the summer 2017 edition of Interface.

The authors of the articles you are about to read all worked tirelessly, and we owe them acknowledgement and significant gratitude for putting this issue together. Without their contributions, we would not be able to deliver the consistent quality of content that you expect in Interface.

We as a division hope to highlight the diverse activities of our members.

In the following pages you will find articles authored by industrial and academic members, with foci ranging from environmental applications to mathematical modeling to large-scale industrial production of metals. Such breadth is evidence that our division’s activities, as has been the case in the past, are ever evolving.

Past ECS President Krishnan Rajeshwar (left) awarding Barry Miller (right) the Edward Goodrich Acheson Award.

Is it possible for an awards program to go full circle? Here at ECS, the answer is a resounding YES!

Consider this: every two years in the fall, The Electrochemical Society honors an outstanding scientist or engineer with the Charles W. Tobias Young Investigator Award and similarly acknowledges the legacy of career achievement through our oldest prize, the Edward Goodrich Acheson Award. In each case, your peers are recognized for scientific contributions within our multi-disciplinary sciences and sustained service to our Society.

So what are we asking of you?

Nominate someone. They say it’s an honor to be nominated because it is.

Who are the best candidates?

The Tobias award applicant will be 40 years of age or younger (by April 1, 2018), whose professional background and Society volunteerism demonstrates a desire for future excellence in teaching and/or research and leadership within ECS. S/he will receive a framed certificate, a $5,000 prize and life membership. The 2016 recipient was Shirley Meng, Associate Professor of NanoEngineering at the University of California San Diego. Dr. Meng is currently the secretary of our largest division and a member of the sponsorship committee.

SemiconductorEngineers have created a high-frequency electronic chip potentially capable of transmitting tens of gigabits of data per second, much faster than the fastest internet available today.

Omeed Momeni, an assistant professor of electrical and computer engineering at University of California, Davis, and doctoral student Hossein Jalili designed the chip using a phased array antenna system. Phased array systems funnel the energy from multiple sources into a single beam that can be narrowly steered and directed to a specific location.

“Phased arrays are pretty difficult to create, especially at higher frequencies,” Momeni says. “We are the first to achieve this much bandwidth at this frequency.”

The chip prototyped by Momeni and Jalili successfully operates at 370 GHz with 52 GHz of bandwidth. For comparison, FM radio waves broadcast between 87.5 and 108 MHz; 4G and LTE cellular networks generally function between 800 MHz and 2.6 GHz with up to 20 MHz of bandwidth.

ECS Intern Spotlight

Laura Villano, Publications Intern (Click to enlarge.)

The purpose of an internship is to benefit both the student and organization. For that reason, I believe my internship at ECS was a success. I gained valuable experience, new skill sets, and many new acquaintances, as well as benefitted the Society. My name is Laura Villano and I am a senior marketing major at The College of New Jersey. During my time at ECS, I worked as an intern for Beth Craanen in the publications department. When I first applied, I was thrilled by the idea of working for a nonprofit and trying to make a difference. The more I learned about ECS and its Free the Science campaign, the more I found myself bragging to my family and friends about the company I interned for.

During my time in the publications department, I performed many marketing duties for ECS’s various publications. The beginning of my internship focused mostly on writing-based projects. I created blog posts and emails regarding subscriptions, journal focus issues, author information sessions, and several other various mini-marketing campaigns. The scope of my internship changed over my six months at ECS, and those duties slowly transformed into more digital advertising and graphic design projects. I transitioned into creating digital advertisements such as banner and carousel ads for the ECS website. I also created flyers about the content in the ECS Digital Library and subscription packages. If you are a member of ECS and attended the New Orleans meeting, you may have also seen some of the larger signage I created!

One of my favorite projects at ECS was helping to redesign the ECS Transactions logo and cover. Unfortunately, I had to leave the internship before the project was carried out but I am excited to see the final product in the future. I thoroughly enjoyed working on the projects with all of the ECS staff. Everyone was friendly and always willing to help.

Spray Drying-Assisted Synthesis of Li3VO4/C/CNTs Composites for High-Performance Lithium Ion Battery Anodes

Published in the “Focus Issue of Selected Papers from IMLB 2016 with Invited Papers Celebrating 25 Years of Lithium Ion Batteries.” Graphite-based materials continue to be the most commonly used anode materials in commercial Li-ion batteries (LIBs). However, the practical application of graphite anodes in largescale LIBs may be hindered by safety issues arising from Li dendrite formation on the surface of the anode when cycling at fast rates.

Focus IssuesThe Journal of The Electrochemical Society (JES) Focus Issue on Mathematical Modeling of Electrochemical Systems at Multiple Scales in Honor of John Newman is now available online, with 72 open access papers published in the ECS Digital Library.

“This focus issue of the Journal of The Electrochemical Society is devoted to the mathematical modeling of electrochemical systems across multiple scales,” the authors say in the focus issue’s preface. “It is dedicated to the work of Professor John Newman from UC Berkeley, who helped establish the field of modeling of electrochemical systems, and is aligned with a previous focus issue and regular symposium on multiscale modeling for electrochemical systems at ECS biannual meetings.”

Newman is a renowned battery researcher and developer of “The Newman Method” — a sophisticated approach to mathematically analyzing complex electrochemical problems. He clarified the physicochemical laws that govern the behavior of electrochemical systems and demonstrated how to use these laws to correctly formulate and solve problems associated with batteries, fuel cells, electrolyzers, and related technologies. He is the author of the book Electrochemical Systems.
