ECS has experienced outstanding growth in several areas as highlighted in our 2016 Annual Report. This is great for the health of the society. As ECS continues the commitment to disseminate electrochemistry and solid state science research, the need for our members becomes ever so important. The question has become – how can ECS best serve its members?

For years ECS has offered member benefits that include access and downloads from the ECS Digital Library, meeting registration and publication discounts, open access article publishing credits, and many more. But, our landscape is changing – as it is for all membership based organizations.

To increase the value of our membership, ECS has or is launching several upcoming programs*:

Researchers at Los Alamos National Laboratory (LANL) are taking a closer look at fuel cell catalysts in hopes of finding a viable alternative to the expensive platinum and platinum-group metal catalysts currently used in fuel cell electrodes. Developments in this area could lead to more affordable next-generation polymer electrolyte fuel cells for vehicles.

The research, led by ECS fellow Piotr Zelenay, looks at the fuel cell catalysts at the atomic level, providing unique insight into the efficiency of non-precious metals for automotive and other applications.

“What makes this exploration especially important is that it enhances our understanding of exactly why these alternative catalysts are active,” Zelenay says. “We’ve been advancing the field, but without understanding the sources of activity; without the structural and functional insights, further progress was going to be very difficult.”

This from LANL:

Platinum aids in both the electrocatalytic oxidation of hydrogen fuel at the anode and electrocatalytic reduction of oxygen from air at the cathode, producing usable electricity. Finding a viable, low-cost PGM-free catalyst alternative is becoming more and more possible, but understanding exactly where and how catalysis is occurring in these new materials has been a long-standing challenge. This is true, Zelenay noted, especially in the fuel cell cathode, where a relatively slow oxygen reduction reaction, or ORR, takes place that requires significant ‘loading’ of platinum.

Researchers have found a way to use magnetic nanoparticle clusters to punch through biofilms to reach bacteria that can foul water treatment systems.

The nanoclusters then deliver bacteriophages—viruses that infect and propagate in bacteria—to destroy the bacteria, usually resistant to chemical disinfection.

Without the pull of a magnetic host, these “phages” disperse in solution, largely fail to penetrate biofilms and allow bacteria to grow in solution and even corrode metal, a costly problem for water distribution systems.

The Rice University lab of environmental engineer Pedro Alvarez and colleagues in China developed and tested clusters that immobilize the phages. A weak magnetic field draws them into biofilms to their targets.

“This novel approach, which arises from the convergence of nanotechnology and virology, has a great potential to treat difficult-to-eradicate biofilms in an effective manner that does not generate harmful disinfection byproducts,” Alvarez says.

Biofilms can be beneficial in some wastewater treatment or industrial fermentation reactors owing to their enhanced reaction rates and resistance to exogenous stresses, says graduate student and co-lead author Pingfeng Yu.

Just a few weeks after France vowed to get gasoline and diesel powered cars off the road by 2040, Australia has joined in on the conversation of transportation transformation. According to a statement, Queensland is looking to kick off an electric vehicle revolution with the implementation of an “electric super highway.”

The highway will incorporate 18 towns and cities in Australia. Officials expect the highway to be completed within the next six months, stretching 1,240 miles along the Queensland’s east coast loaded with 18 fast-charging stations that can charge a car in 30 minutes, allowing electric vehicle drivers to make it from the state’s southern border to the far north.

“EVs can provide not only a reduced fuel cost for Queenslanders, but an environmentally-friendly transport option, particularly when charged from renewable energy,” says Environment Minister and Acting Main Roads Minister Steven Miles. “The Queensland Electric Super Highway has the potential to revolutionize the way we travel around Queensland in the future.”

Researchers from Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland have successfully created food out of electricity and carbon dioxide, which they hope could one day be used to help solve world hunger.

According to reports, the single-cell protein can be produced wherever renewable energy is available, with uses ranging from food to animal feed.

“In practice, all the raw materials are available from the air. In the future, the technology can be transported to, for instance, deserts and other areas facing famine,” co-author of the research, Juha-Pekka Pitkanen, said in a statement. “One possible alternative is a home reactor, a type of domestic appliance that the consumer can use to produce the needed protein.”

The researchers achieved this result by exposing those raw materials and putting them in a small “protein reactor.” After exposing it to electrolysis, chemical decomposition occurs. After about two weeks, one gram of powder made of 50 percent protein and 25 percent carbohydrate.

A new device improves on the sensitivity and versatility of sensors that detect doping in athletics, bomb-making chemicals, or traces of drugs. It could also cut costs.

To conduct these kinds of searches, scientists often shine light on the materials they’re analyzing. This approach is known as spectroscopy, and it involves studying how light interacts with trace amounts of matter.

One of the more effective types of spectroscopy is infrared absorption spectroscopy, which scientists use to sleuth out performance-enhancing drugs in blood samples and tiny particles of explosives in the air.

While infrared absorption spectroscopy has improved greatly in the last 100 years, researchers are still working to improve the technology.

“This new optical device has the potential to improve our abilities to detect all sorts of biological and chemical samples,” says Qiaoqiang Gan, associate professor of electrical engineering in the School of Engineering and Applied Sciences at University at Buffalo. Gan is lead author of the study.

Scientists have turned wood into an electrical conductor by making its surface graphene.

Chemist James Tour of Rice University and his colleagues used a laser to blacken a thin film pattern onto a block of pine. The pattern is laser-induced graphene (LIG), a form of the atom-thin carbon material discovered at Rice in 2014.

“It’s a union of the archaic with the newest nanomaterial into a single composite structure,” Tour says.

Previous iterations of LIG were made by heating the surface of a sheet of polyimide, an inexpensive plastic, with a laser. Rather than a flat sheet of hexagonal carbon atoms, LIG is a foam of graphene sheets with one edge attached to the underlying surface and chemically active edges exposed to the air.

Not just any polyimide would produce LIG, and some woods work better than others, Tour says. The research team tried birch and oak, but found that pine’s cross-linked lignocellulose structure made it better for the production of high-quality graphene than woods with a lower lignin content. Lignin is the complex organic polymer that forms rigid cell walls in wood.

A recently published article in The Scientist tells a growingly familiar tale in scholarly publishing: predatory publishers taking advantage of, and often times profiting from, researchers across the globe.

The term “predatory publishers” was coined by University of Colorado Denver librarian, Jeffrey Beall, nearly a decade ago. These publishers disseminate plagiarized or poorly reviewed content, taking advantage of a pay-to-publish open access system by charging authors high prices to disseminate their content while all but eliminating the peer review process. In the case of the article published in The Scientist, these predatory journals even trick established researchers to agree to have their names listed on editorial boards, falsley presenting themselves as credible start-up journals. While this may bolster a journal’s credibility at first glance, it often doesn’t go beyond a name listed on a website, with little to no communication from the journal to the editors.

And if predatory publishers can’t trick honest researchers, that publisher may just recruit a fake editor. A recent investigation, spearheaded by Nature, found that dozens of academic journals have been recruiting fake editors and offering them a place on their editorial board.

According to reports from the Hanken School of Economics, predatory journals increased their publication volume from 53,000 to 420,000 articles per year between 2010 and 2014. Taking article processing charges into account, the report estimates that all-in-all, the predatory publishing market was worth at $74 million in 2014.
