Lithium batteries made with asphalt could charge 10 to 20 times faster than the commercial lithium-ion batteries currently available.

The researchers developed anodes comprising porous carbon made from asphalt that show exceptional stability after more than 500 charge-discharge cycles.

A high-current density of 20 milliamps per square centimeter demonstrates the material’s promise for use in rapid charge and discharge devices that require high-power density.

“The capacity of these batteries is enormous, but what is equally remarkable is that we can bring them from zero charge to full charge in five minutes, rather than the typical two hours or more needed with other batteries,” says James Tour, the chair in chemistry and a professor of computer science and of materials science and nanoengineering at Rice University.

The Tour lab previously used a derivative of asphalt—specifically, untreated gilsonite, the same type used for the battery—to capture greenhouse gases from natural gas. This time, the researchers mixed asphalt with conductive graphene nanoribbons and coated the composite with lithium metal through electrochemical deposition.

Researchers have created a way to look inside fuel cells to see the chemical processes that lead them to breakdown.

Fuel cells could someday generate electricity for nearly any device that’s battery-powered, including automobiles, laptops, and cellphones. Typically using hydrogen as fuel and air as an oxidant, fuel cells are cleaner than internal combustion engines because they produce power via electrochemical reactions. Since water is their primary product, they considerably reduce pollution.

The oxidation, or breakdown, of a fuel cell’s central electrolyte membrane can shorten their lifespan. The process leads to formation of holes in the membrane and can ultimately cause a chemical short circuit. Engineers created the new technique to examine the rate at which this oxidation occurs with hopes of finding out how to make fuel cells last longer.

Using fluorescence spectroscopy inside the fuel cell, they are able to probe the formation of the chemicals responsible for the oxidation, namely free radicals, during operation. The technique could be a game changer when it comes to understanding how the cells break down, and designing mitigation strategies that would extend the fuel cell’s lifetime.

“If you buy a device—a car, a cell phone—you want it to last as long as possible,” says Vijay Ramani, professor of environment & energy at the School of Engineering & Applied Science at Washington University in St. Louis.

It’s been a busy summer for open access (OA) in Europe. On one hand, nationally coordinated efforts in places like Finland and Germany have sought (unsuccessfully so far) to pressure Elsevier into better subscription pricing and OA options. On the other hand, a group of early career researchers (ECRs) at the University of Cambridge are looking to mobilize fellow ECRs to embrace open models that are not controlled by commercial entities. In my view, these divergent approaches illustrate why we should focus our collective energies away from strategies in which commercial interests retain control under new economic conditions (see also, proposals to flip subscription payments to APCs), and towards working with ECRs and others who envision a return of scholarly dissemination responsibility to the academy.

One aspect of the Finnish No Deal, No Review boycott that seems especially telling is that signees refuse to serve as reviewers or editors for Elsevier journals, but make no such commitment in terms of ceasing to submit articles to those same journals for publication. That is probably a bridge too far for many who feel compelled to meet traditional promotion and tenure expectations of publishing in prestigious journals that are often controlled by publishers such as Elsevier. While the Finnish position is admirable in a general sense, even if the demands for better economic terms are met, Elsevier would remain a profit-driven conduit through which dissemination occurs, though with slightly less robust profit margins.

Researchers have created a small, thin, biodegradable sensor that could monitor the temperature of food in transit.

Microsensors are already used in many different applications today, such as the detection of poisonous gases. They are also part of miniaturized transmitter/receiver systems, such as the ubiquitous RFID chips.

As the sensors often contain precious metals that are harmful to both the environment and human health, however, they are not suitable for medical applications involving direct contact with the human body or for inclusion in food products. There is therefore a high level of interest, both in research and industry, in developing microsensors made from non-toxic materials that are also biodegradable.

Minhua Shao: As an associate editor, I hope to accelerate the manuscript handling process by identifying suitable reviewers and making fair decisions. I also hope to promote the journal at conferences and among peers, attracting high-quality manuscripts.

ECS: How has scholarly publishing evolved throughout your career?

MS: Scholarly publishing has changed significantly in the past two decades. Now researchers have many more choices on which journals to publish their results. The adoption of the so-called impact factor in assessing the quality of journals/papers has misled the scientific community. More seriously, there is a trend that scholarly publishing is more of a business than a platform for sharing research results.

Over the summer, librarians and academic leaders in Germany came together to lead a push in taking down the paywalls that block access to so many scientific research articles. The initiative, named Projekt DEAL, represents a bold push toward open access that could change the landscape of academic publishing.

The latest developments in Projekt DEAL pick up on a battle now over two years in the making, where libraries and universities in Germany have united in pushing large publishers to adopt a new business model. The institutions are looking to forego the typical subscription-based academic publishing business model in lieu of paying an annual lump sum that covers publications costs of all papers whose first authors are associated with German institutions.

The concept behind Projekt DEAL is relatively straight forward: multiply the number of papers with first authors associated with German institutions by a reasonable fee per paper. The institutions would pay that amount and those papers would then be published open access, available to everyone around the world, in exchange for free access to all of the publisher’s online content for the German institutions. This would not only mark a huge step in the open access movement, but would alleviate some of the financial burden facing libraries paying for high-cost journal subscriptions.

But this push isn’t the first of its kind. According to reports from Science, institutions from the Netherlands, Finland, Austria, and United Kingdom have all worked for similar agreements. The results, however, have been less than the libraries and universities had hoped for.
