For the last decade, the city of Las Vegas has been working toward generating 100 percent of its energy from renewable source. Now, city officials state that goal has been met.

About one year ago, the city partnered with the company NV Energy, a public utility that distributes energy across the state of Nevada, to help Las Vegas reach its clean energy goal. NV Energy official recently announced that everything from City Hall to community centers are now running on clean energy after the finalization of Boulder Solar 1.

The Boulder Solar plant was built by California sustainable energy company SunPower. The 100-megawatt solar plant is located in the Eldorado Valley of Boulder City, NV.

Las Vegas’ major, Carolyn Goodman, hopes that this move will but the city on the path to be a “world leader in sustainability.”

New research out of the University of California, Riverside reveals a transparent, self-healing, highly stretchable material that can be electrically activated to power artificial muscles or improve batteries and electronic devices.

The researchers behind the development believe that this new material could be used to extend the lifetime of lithium-ion batteries in electric vehicles, improve medical and environmental biosensors, and even allow robots to self-heal after mechanical failure.

“Creating a material with all these properties has been a puzzle for years,” says Chao Wang, co-author of the recently published research. “We did that and now are just beginning to explore the applications.”

According to the research, the low-cost material can stretch 50 times its original length and can complete heal in 24 hours after being cut.

Corrosion is a dangerous and extremely costly problem. Because of it, buildings and bridges can collapse, oil pipelines break, and water sources become contaminated. Currently, the global cost estimated to repair corrosive effects comes in around $2.5 trillion per year.

But researchers in the field of corrosion science and technology like Robert Kelly, the 2016 winner of ECS’s Corrosion Division H. H. Uhlig Award, are looking to change the way we deal with the effects of corrosion from reactive to predictive.

“One of the sayings about corrosion is that we can explain everything and predict nothing,” Kelly says. “We’re looking to turn that around.”

Corrosion time machine

Kelly, AT&T Professor of Engineering in the University of Virginia’s Department of Materials Science and Engineering, is working with his team to better understand what’s controlling the localized corrosion process with a newly designed accelerated test that can predict the corrosive effects on certain materials when they’re put into their natural environment.

The National Inventors Hall of Fame was founded in 1973 and continues to honor individuals among us who strive to make the world a better place through innovation. With a simple mission to recognize inventors and invention, the National Inventors Hall of Fame announces a call for nominations for 2017 recognition.

ECS is proud to partner with the National Inventors Hall of Fame. The chair of the ECS Honors & Awards Committee serves as our representative for the four-year term; Dr. Peter Fedkiw is currently in both roles. The Honors & Awards Committee has an External Awards Subcommittee specifically designated to assist in applications such as these.

Take time to consider a scientist or engineer among us who is worthy of a nomination. View the new National Inventors Hall of Fame web site for details about the award program, the corresponding STEM education initiatives and the list of inventors whose ingenuity we take advantage of each day. Then reach out to us for assistance is the nomination process via awards@electrochem.org.

ECS has an inductee that you might be familiar with Dr. Esther Takeuchi — materials scientist, chemical engineer, ECS member since 1985 and former Society President — was inducted into the National Inventors Hall of Fame in 2011 for developing the battery that enabled implantable cardiac defibrillators (ICDs). The invention afforded Dr. Takeuchi the 2009 National Medal of Technology and Innovation.

The deadline for nominations for the class of 2018 is March 31, 2017.

Since 1902, ECS has continuously published innovative, impactful research in the field of electrochemical and solid state science and technology. From the first publication of the Transactions of the American Electrochemical Society over 100 years ago to the over 1,700 journal papers published in the Society’s Digital Library every year, ECS has disseminated a massive amount of research since its establishment.

One ECS member happened to have a good deal of that research sitting in his basement office.

John Murray joined ECS in 1962, which is when he began receiving the paper version of the Journal of The Electrochemical Society (JES). Since then, he’s stowed the paperbound research in his basement, making sure to transfer it wherever his career took him. Now, that collection has made its way from his home in Timonium, MD to ECS headquarters in Pennington, NJ.

Cultivating a collection

Murray’s electrochemical career began at Allis-Chalmers Corp. Research Division in West Allis, WI, where he worked on catalysts and electrodes that would assist in the development of hydrogen oxygen fuel cells for NASA. When the company hit financial issues and sold its research division to Teledyne Technologies, Murray was one of just nine employees to keep his position. That took him and his wife Stephany to Timonium, MD, where they currently live.

And of course, where the around 700 pounds of ECS journals live as well.

Truth seems to be an increasingly flexible concept in politics. At least that’s the impression the Oxford English Dictionary gave recently, as it declared “post-truth” the 2016 Word of the Year. What happens when decisions are based on misleading or blatantly wrong information? The answer is quite simple – our airplanes would be less safe, our medical treatments less effective, our economy less competitive globally, and on and on.

Many scientists and science communicators have grappled with disregard for, or inappropriate use of, scientific evidence for years – especially around contentious issues like the causes of global warming, or the benefits of vaccinating children. A long debunked study on links between vaccinations and autism, for instance, cost the researcher his medical license but continues to keep vaccination rates lower than they should be.

Only recently, however, have people begun to think systematically about what actually works to promote better public discourse and decision-making around what is sometimes controversial science. Of course scientists would like to rely on evidence, generated by research, to gain insights into how to most effectively convey to others what they know and do.

As it turns out, the science on how to best communicate science across different issues, social settings and audiences has not led to easy-to-follow, concrete recommendations.

Nature announced on December 8 that Elsevier has launched a new journal quality index, called CiteScore, which will be based on Elsevier’s Scopus citation database and will compete with the longstanding and influential Journal Impact Factor (IF).

Conflict of interest

One can hardly fault Elsevier for producing this metric, which is well positioned to compete with the Impact Factor. But for researchers and librarians, there are serious concerns about CiteScore. Having a for-profit entity that is also a journal publisher in charge of a journal publication metric creates a conflict of interest, and is inherently problematic. The eigenfactor team Carl T. Bergstrom and Jevin West have done some early analysis of how Elsevier journals tend to rank via CiteScore versus the Impact Factor, and conclude that “Elsevier journals are getting just over a 25% boost relative to what we would expect given their Impact Factor scores.” Looking at journals other than Nature journals – which take quite a hit under the CiteScore because of what Phil Davis refers to as Citescore’s “overt biases against journals that publish a lot of front-matter” — Elsevier journals still get a boost (15%) in comparison with Impact Factor.

Perpetuating problems of journal prestige in promotion and tenure

But more broadly, the appearance of another measure of journal impact reinforces existing problems with the scholarly publishing market, where journal brand as a proxy for research quality drives promotion and tenure decisions. This tying of professional advancement, including grant awards, to publication in a small number of high prestige publications contributes to monopoly power and resulting hyperinflation in the scholarly publishing market. Indeed, I was recently informed by a large commercial journal publisher that a journal’s Impact Factor is a key consideration in setting the price increase for that title—and was the first reason mentioned to justify increases.

Lithium-ion batteries supply billions of portable devices with energy. While current Li-ion battery designs may be sufficient for applications such as smartphones and tablets, the rise of electric vehicles and power storage systems demands new battery technology with new electrode materials and electrolytes.

ECS student member Michael Metzger is looking to address that issue by developing a new battery test cell that can investigate anionic and cationic reactions separately.

Along with Benjamin Strehle, Sophie Slochenbach, and ECS Fellow Hubert A. Gasteiger, Metzger and company published their new findings in the Journal of The Elechemical Society in two open access papers.

(READ: “Origin of H₂ Evolution in LIBs: H₂O Reduction vs. Electrolyte Oxidation” and “Hydrolysis of Ethylene Carbonate with Water and Hydroxide under Battery Operating Conditions“)

“Manufacturers of rechargeable batteries are building on the proven lithium-ion technology, which has been deployed in mobile devices like laptops and cell phones for many years,” says Metzger, the 2016 recipient of ECS’s Herbert H. Uhlig Summer Fellowship. “However, the challenge of adapting this technology to the demands of electromobility and stationary electric power storage is not trivial.”
