Researchers have developed a prototype device that mimics natural photosynthesis to produce ethylene gas using only sunlight, water, and carbon dioxide.

The novel method, which produces ethylene at room temperature and pressure using benign chemicals, could be scaled up to provide a more eco-friendly and sustainable alternative to the current method of ethylene production.

Ethylene, which is the building block of polyethylene, is an important chemical feedstock produced in large quantities for manufacturing plastics, rubber, and fibers. More than 170 million tons of ethylene were produced worldwide in 2015 alone, and the global demand is expected to exceed 220 million tons by 2020.

New research stitches together the best parts of several different bacteria to synthesize a new biofuel product that matches current engines better than previously produced biofuels.

“My lab is interested in developing microbial biosynthetic processes to make biofuels, chemicals, and materials with tailored structures and properties,” says Fuzhong Zhang, associate professor at the School of Engineering & Applied Science at Washington University in St. Louis. “Previously, we engineered E.coli to produce a precursor compound that leads to the production of advanced biofuels. In this work, we took the next step toward the actual manufacture.”

Zhang’s research focuses on engineering metabolic pathways that, when optimized, allow the bacteria to act as a biofuel generator. In its latest findings, recently published in Biotechnology for Biofuels, Zhang’s lab used the best bits of several other species—including a well-known pathogen—to enable E. coli to produce branched, long-chain fatty alcohol (BLFL), a substance that can be used as a freeze-resistant, liquid biofuel.

On Thursday, December 14, from 12:00 pm to 1:00 pm EST, ECS President Johna Leddy and ECS Transactions Editor Jeffrey Fergus will answer your questions about open science, the Free the Science initiative, and the Society’s forthcoming preprint server, ECSarXiv, during ECS’s second Reddit Ask Me Anything (AMA).

The online discussion will take place as part of the /r/Science community’s Science AMA Series. All are encouraged to ask questions and participate in the discussion.

Any questions related to the topics listed above are fair game. Start preparing yours!

We are podcasting the question and answer section of the live broadcast ECS did of the OpenCon satellite event held at the 232nd ECS Meeting in October of 2017.

ECS OpenCon was a 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.

ECS was the first scholarly society to host an OpenCon satellite event.

The ECS Canada Section recently awarded Leah Ellis and Yurij Mozharivskyj the 2017 Canada Section Student Award and W. Lash Miller Award, respectively.

Canada Section Student Award

The Canada Section Student Award was established in 1987 to recognize promising young scientists and engineers in the field of electrochemical power sources. The 2017 award went to Leah Ellis, a PhD candidate at Dalhousie University working in lithium-ion battery research.

“This ECS Canada Section Student Award is very prestigious,” Ellis said. “Looking at the list of past award winners, I feel very honored and humbled to be included in this list. The award is very inspiring to me, and I hope to live up to its reputation.”

In a recent interview, ReasonsTV sat down with PLOS co-founder Michael Eisen to discuss open access, the academic publishing monopoly, and ways to democratize scientific progress.

PS: ECS’s Free the Science initiative is a move toward a future that embraces open science to further advance research in our field. This is a long-term vision for transformative change in the traditional models of communicating scholarly research.

Other ECS programs that advance the shift to open science include the upcoming launch of ECSarXiv, a preprint server through a partnership with the Center for Open Science, enhanced research dissemination with Research4Life, ECS OpenCon, and expanding our publications to include more research in data sciences.

New research indicates that poplar trees could be an economically viable biofuel material.

In the quest to produce affordable biofuels, poplars are one of the Pacific Northwest’s best bets—the trees are abundant, fast-growing, adaptable to many terrains, and their wood can become substances used in biofuel and high-value chemicals that we rely on in our daily lives.

But even as researchers test poplars’ potential to morph into everything from ethanol to chemicals in cosmetics and detergents, a commercial-scale processing plant for poplars has yet to be achieved. This is mainly because production costs still are not competitive with the current price of oil.

Now, a team of researchers is trying to make poplar a viable competitor by testing the production of younger poplar trees that could be harvested more frequently—after only two or three years—instead of the usual 10- to 20-year cycle.

Graduate students in the U.S. are fighting the House Republican proposed tax plan, demonstrating protests and walk-outs in more than 40 universities across the country on Wednesday, November 29.

The current bill, which passed the House this month, includes a provision that would turn tuition waivers into taxable income. Students and economists alike state that such a provision would make continuing education unaffordable and inaccessible to many.

For many students pursing a PhD, tuition waivers and stipends are essential in making such a degree affordable. In return for taking up a position as a teaching assistant, fellow, or as a research assistant in a lab, graduate student receive a small stipend to support themselves, which Forbes estimates falls anywhere between $20,000 and $30,000 per year. Additionally, students receive tuition waivers ranging from $12,000 to $50,000 per year (depending on the university), which are paid directly by the university to the university on the student’s behalf. While students pay taxes on the stipend, the tuition waiver is non-taxable income that never even passes through the student’s hands.

The new GOP tax plan could change all of that.

A team of researchers from the Joint Center for Energy Storage Research is taking a potential major step toward developing energy dense, safe solid state magnesium-ion batteries.

This research marks another step in pursing batteries that utilize solid electrolytes, which could offer significant safety benefits over conventional lithium-ion batteries.

The work was developed out of efforts to create a magnesium battery with a liquid electrolyte. While magnesium has promising properties for energy storage, the researchers had trouble finding a viable liquid electrolyte for the technology that wouldn’t corrode.

“Magnesium is such a new technology, it doesn’t have any good liquid electrolytes,” said Gerbrand Ceder, co-author of the research and member of ECS. “We thought, why not leapfrog and make a solid state electrolyte?”

The Journal of The Electrochemical Society Focus Issue on Ubiquitous Sensors and Systems for IoT is currently accepting manuscripts.

Ubiquitous sensors are becoming an integral part of Internet of Things (IoT) applications, and progress in this domain can be seen each month. The promise is that everyone and everything will be connected via wireless data collection, and services like healthcare will be brought to everyone, everywhere, anytime, for virtually any need.

These devices sense the environment and provide applications in home automation, home safety and comfort, and personal health. At a macro level they provide data for smart cities, smart agriculture, water conservation, energy efficiency industry 4.0, and Society 5.0.

Other applications include supply chain management, transportation, and logistics.
