A new bendable lithium-ion battery prototype continues delivering electricity even when cut into pieces, submerged in water, or struck with force.
“We are very encouraged by the feedback we are receiving,” says Jeffrey P. Maranchi, manager of the materials science program at the Johns Hopkins Applied Physics Laboratory. “We are not that far away from testing in the field.”
Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, report engineers.
Materials scientist Rouzbeh Shahsavari of Rice University and alumnus Navid Sakhavand first built atom-level computer models of pillared graphene—sheets of graphene connected by covalently bonded carbon nanotubes—to discover their strength and electrical properties as well as their thermal conductivity.
In a new study, they found that manipulating the joints between the nanotubes and graphene has a significant impact on the material’s ability to direct heat. That could be important as electronic devices shrink and require more sophisticated heat sinks.
A copyright battle between ResearchGate and a handful of publishing giants continues as the academic social network bends to pending legal pressure, restricting access to at least 1.7 million scholarly articles.
This move comes after a push from the Coalition for Responsible Sharing in early October, stating that if ResearchGate does not work to remedy was the CRS deemed “copyright infringements,” that the group will begin taking formal steps to address the issue. The CRS consists of ACS Publications, Brill, Elsevier, Wiley, and Wolters Kluwer.
“ResearchGate’s primary service is taking high-quality content written and published by others and making as many as 7 million copyrighted articles—40% of its total content—freely available via its for-profit platform,” said an October 5 statement from CRS. “Numerous attempts to agree with ResearchGate on amicable solutions . . . remained unsuccessful. Members of the Coalition for Responsible Sharing are therefore now resorting to formal means to alter ResearchGate’s damaging practices.”
As sustainable technologies continue to expand into the marketplace, the demand for better batteries rises. Many researchers in the field are looking toward all-solid-state batteries as a promising venture, citing safety and energy density properties. Now, one company is looking to take that work from the lab to the marketplace.
Electric car maker Fisker has recently filed patents for solid state lithium-ion batteries, stating that mass scale production could begin as soon as 2023. The patent covers novel materials and manufacturing processes that the company plans to use to develop automotive-ready batteries.
Unlike other types of rechargeable batteries that use liquid electrodes and electrolytes, solid state batteries utilize both solid electrodes and solid electrolytes. While liquid electrolytes are efficient in conducting ions, there are certain safety hazards attached (i.e. fires if the battery overheats or is short-circuited). In addition to better safety, solid electrodes could also impact battery cost and energy density, opening up new possibilities for large scale storage applications.
New research is building a bridge from nature’s chemistry to greener, more efficient synthetic chemistry.
Researchers analyzed biocatalysts evolved by nature for their effectiveness in a variety of synthetic chemical reactions. The results, published in Nature Chemistry, open the door to promising practices for chemists, pointing to not only more efficient but also more powerful tools for chemists.
The researchers started with microorganisms that have, over the millennia, developed complex chemical reactions to create molecules with important biological activity for various purposes, such as defense mechanisms. The scientists then analyzed the chemical pathways that give rise to these potentially useful molecules to determine how they can be repurposed to create compounds synthetically in the lab.
“Nature has evolved catalytic tools that would enable chemists to build molecules that we can’t easily build just using traditional chemistry,” says senior study author Alison Narayan, assistant professor at the University of Michigan Life Sciences Institute. “Our work bridges the two worlds of biosynthesis and synthetic chemistry.”

Matthew Murbach, co-founder of Battery Informatics, Inc.
Matthew Murbach, founding president of the ECS student chapter and the University of Washington (UW) and motivating force behind the launch of the ECS Data Sciences Hack Day, has been named to the Forbes 30 Under 30 list in the area of energy. According to Forbes, Murbach was recognized for his work “to commercialize battery management breakthroughs to enable faster charging, finer control over degradation and longer lifetimes.”
Murbach is co-founder of Battery Informatics, Inc. and a PhD student in chemical engineering at the University of Washington. Murbach’s PhD research is exploring new ways to diagnose the state of health in batteries, a critical and expensive asset in the emerging low carbon energy economy.
Battery Informatics is a next-generation battery management company focused on capturing the maximum value of energy storage through software solutions. The company is licensing UW intellectual property to extract the maximum value from these battery assets over the whole battery lifecycle. Just this month, they are flipping the switch on their first customer installation.
Joaquin Rodriguez Lopez presenting his work at the Toyota Research Institute of North America in Ann Arbor, Michigan.
In 2014, ECS and Toyota Research Institute of North America came together to establish the ECS Toyota Young Investigator Fellowship to support young researchers working in green energy technology. The partnership between ECS and Toyota aims to leverage the Society’s network of researchers, awarding fellowship winners a minimum of $50,000 to pursue novel research over a one year period.
“We try to give folks the opportunity to do research that is a little more outside of the box,” said Paul Fanson, manager of Toyota’s North American Research Strategy Office, “where they might have difficulty getting funding somewhere else.”
As this year winds down and the 2016-2017 fellows come to the tail end of the research period, fellowship winners Elizabeth Biddinger, City College of New York; Joaquin Rodriguez Lopez, University of Illinois at Urbana-Champaign; and Joshua Snyder, Drexel University recently took their work to Toyota’s site in Ann Arbor, Michigan, to report their findings, connect with industry researchers, and explore opportunities that extend beyond the funding time period.
The ECS Lecture during the 232nd ECS Meeting in National Harbor, MD, was delivered by Steven Chu. Chu is currently the William R. Kenan, Jr., Professor of Physics and Professor of Molecular & Cellular Physiology at Stanford. Previously, he served as U.S. Secretary of Energy under President Obama and was the co-recipient of the 1997 Nobel Prize in Physics for his contribution to laser cooling and atom trapping.
Chu’s ECS Lecture, “The Role of Electrochemistry in our Transition to Sustainable Energy,” focused on the risks society is facing due to changing climate, the evolving energy landscape, and the role of electrochemistry in providing critical technological advances.
During his lecture, Chu outlined the risks that modern society faces, which demand technological innovation to provide solutions. Namely, Chu stated that the rising climate poses significant risks to the global community. According to Chu, the Earth has warmed by an alarming one degree Celsius since 1975.
“One degree Celsius does not sound like a lot, but just a couple of degrees warmer would make a dramatic difference,” Chu said. “If the Earth does warm by two degrees Celsius, Boston will be underwater.”
