Reports of a woman’s headphones catching fire while on a flight from Bejing to Melbourne has once again heightened interest in lithium-ion battery safety. According to the Australian Transport Safety Bureau, the incident occurred while the woman was sleeping mid-flight wearing battery-powered headphones.

Early in 2016, battery expert and ECS fellow, K.M. Abraham, talked to ECS about lithium-ion battery safety concerns amidst reports of exploding hoverboards. Below are some excerpts of what he had to say.

“It is safe to say that these well-publicized hazardous events are rooted in the uncontrolled release of the large amount of energy stored in lithium-ion batteries as a result of manufacturing defects, inferior active and inactive materials used to build cells and battery packs, substandard manufacturing and quality control practices by a small fraction of cell manufacturers, and user abuses of overcharge and over-discharge, short-circuit, external thermal shocks and violent mechanical impacts,” Abraham told ECS. “All of these mistreatments can lead lithium-ion batteries to thermal runaway reactions accompanied by the release of hot combustible organic solvents which catch fire upon contact with oxygen in the atmosphere.”

Sensors have become intertwined with our everyday life. From the cars to phones to medical devices, sensors are embedded in many of the technologies we consistently use.

However, microelectromechanical systems (MEMS) accelerometers, which measure the rate of change in an object’s speed, can be tricked, according to a new study from the University of Michigan.

This from the University of Michigan:

Researchers used precisely tuned acoustic tones to deceive 15 different models of accelerometers into registering movement that never occurred. The approach served as a backdoor into the devices—enabling the researchers to control other aspects of the system.

One of the keys to developing a successful electric vehicle relies on energy storage technology. For an EV to be successful in the marketplace, it must be able to travel longer distances (i.e. over 300 miles on a single charge).

A team of researchers from Georgia Institute of Technology, including ECS fellow Meilin Liu, has recently created a nanofiber that they believe could enable the next generation of rechargeable batteries, and with it, EVs. The recently published research describes the team’s development of double perovskite nanofibers that can be used as highly efficient catalysts in fast oxygen evolution reactions. Improvements in this key process could open new possibilities for metal-air batteries.

“Metal-air batteries, such as those that could power electric vehicles in the future, are able to store a lot of energy in a much smaller space than current batteries,” Liu says. “The problem is that the batteries lack a cost-efficient catalyst to improve their efficiency. This new catalyst will improve that process.”

Richard Poynder (@RickyPo) is well-known and well-respected in the open access community, especially for his “Open and Shut?” blog. Poynder has written an excellent post, which is part interview with Philip Cohen, founder of the SocArXiv preprint server, and part synopsis of the resurgent preprint server movement. The precursor of them all is arXiv, which was founded way back in 1991. Poynder asks, can preprint servers “gain sufficient traction, impetus, and focus to push the revolution the open access movement began in a more desirable direction?”

The post also talks a good bit about the preprint server framework created by the Center for Open Science (COS). ECS, who is working with COS on launching our own preprint server, gets several mentions in the article as well. In this age of 8-second attention spans, it’s a long article, but it’s well worth the read.

Editor’s note: The following is a roundup of archival stories.

On March 14, or 3/14, mathematicians and other obscure-holiday aficionados celebrate Pi Day, honoring π, the Greek symbol representing an irrational number that begins with 3.14. Pi, as schoolteachers everywhere repeat, represents the ratio of a circle’s circumference to its diameter.

What is Pi Day, and what, really, do we know about π anyway? Here are three-and-bit-more articles to round out your Pi Day festivities.

A silly holiday

First off, a reflection on this “holiday” construct. Pi itself is very important, writes mathematics professor Daniel Ullman of George Washington University, but celebrating it is absurd:

The Gregorian calendar, the decimal system, the Greek alphabet, and pies are relatively modern, human-made inventions, chosen arbitrarily among many equivalent choices. Of course a mood-boosting piece of lemon meringue could be just what many math lovers need in the middle of March at the end of a long winter. But there’s an element of absurdity to celebrating π by noting its connections with these ephemera, which have themselves no connection to π at all, just as absurd as it would be to celebrate Earth Day by eating foods that start with the letter “E.”

And yet, here we are, looking at the calendar and getting goofily giddy about the sequence of numbers it shows us.

ECS is committed to open access through Free the Science, an initiative to completely open our research library and implement open science tools to further scientific advancement in our fields of research.

Our efforts are part of a much larger movement happening across the world. The Open Research Funders Group was announced late last year with foundational support from big names like the Bill & Melinda Gates Foundation, Alfred P. Sloan Foundation, Laura and John Arnold Foundation, and the John Templeton Foundation, to name a few. Recently, the James S. McDonnell Foundation joined the group that is committed to increasing access to research outputs. Using their positions as major funding institutions, the group believes that openness accelerates discovery, reduces information-sharing gaps, encourages innovations, and promotes reproducibility. See a complete list of members of the Open Research Funders Group here.

Former U.S. Vice President Joe Biden announced in a speech to the American Association for Cancer Research that open access, open data, and new research incentives are the best way to contribute to the fight against cancer. In line with his Cancer Moonshot initiative, Biden laid out a series of policy priorities to incentivize open sharing of research data and open access to research articles.

ECS isn’t the only one celebrating an anniversary this year. As we celebrate 115 years of excellence as a publisher, meeting convener, and multi-faceted scientific society, this year also marks an important 15-year milestone in the open access movement. In 2002, the Budapest Open Access Initiative was hosted by the Open Society Foundations and to this day serves as a landmark meeting in communicating the importance and urgency of open access necessities.

The participants in the conference served as the founding researchers of open access, drafting a widely circulated declaration to articulate the goals of the open access (OA) movement. This declaration was signed by over 5,000 organizations and individuals, including ECS.

The declaration reads in part:

Removing access barriers to this literature will accelerate research, enrich education, share the learning of the rich with the poor and the poor with the rich, make this literature as useful as it can be, and lay the foundation for uniting humanity in a common intellectual conversation and quest for knowledge.
