Corroded pipelinesFor many centuries, lead was the favored material for water pipes due to its malleability. However, the health hazards associated with ingesting lead were not fully understood until the late 1900s. Now, with a massive water infrastructure that utilizes lead pipes and instances of corrosion and leaching causing development and neurological effects in young children consuming tainted water, researchers from Washington University in St. Louis are researching the potential impact of replacing lead pipes.

According to the research team, digging up lead pipes to replace them with copper piping would not only be extremely expensive, but potentially dangerous. The team developed a new way to model and track where dislodged lead particles might be transported during the replacement process.

“We all know lead is not safe, it needs to go,” says Pratim Biswas, past ECS member and chair of Energy, Environmental and Chemical Engineering at the School of Engineering & Applied Science. “This is the first comprehensive model that works as a tool to help drinking-water utility companies and others to predict the outcome of an action. If they have the necessary information of a potential action, they can run this model and it can advise them on how best to proceed with a pipe replacement to ensure there are no adverse effects.”

Carbon dioxideChemists have engineered a molecule that uses light or electricity to convert carbon dioxide into carbon monoxide—a carbon-neutral fuel source—more efficiently than any other method of “carbon reduction.”

“If you can create an efficient enough molecule for this reaction, it will produce energy that is free and storable in the form of fuels,” says study leader and Liang-shi Li, associate professor in the chemistry department at Indiana University Bloomington. “This study is a major leap in that direction.”

Burning fuel—such as carbon monoxide—produces carbon dioxide and releases energy. Turning carbon dioxide back into fuel requires at least the same amount of energy. A major goal among scientists has been decreasing the excess energy needed.

This is exactly what Li’s molecule achieves: requiring the least amount of energy reported thus far to drive the formation of carbon monoxide. The molecule—a nanographene-rhenium complex connected via an organic compound known as bipyridine—triggers a highly efficient reaction that converts carbon dioxide to carbon monoxide.

The ability to efficiently and exclusively create carbon monoxide is significant due to the molecule’s versatility.

Free Content, Free the Science

ECS at 115
We are fast approaching the exact date of our 115th anniversary. On April 2, 1902, the American Electrochemical Society (as ECS was called in the beginning) held its first meeting in Philadelphia. In the transactions of the first meeting, President Joseph Richard’s wrote:

Such is the force, the necessary condition, which has brought into existence The American Electrochemical Society… being, therefore, a necessity, a pressing need, its formation was inevitable… The results having justified the insight of the projectors of the society, the first meeting has been an enthusiastic success, the organization now exists, its future assured of usefulness. With confidence we stand out to sea.

Today, we feel the same “necessary condition” and “pressing need” for inevitable change. This time, however, our goal is to change our publishing business model to completely open the ECS Digital Library while maintaining our high standards of peer review and adapting new technologies and principles related to open science.

We believe that we have an imperative to implement Free the Science, both from a research standpoint—our sciences have broad implications for human and environmental sustainability—and from a scholarly communication perspective—we believe everyone should have the same access to share and acquire knowledge. With open access and open research receiving such a crescendo of support from governments, funders, advocates, and scientists, we believe that ECS can provide leadership in the impending publishing revolution.

BatteryReports 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.

BatteryOne 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.”

Join Us to Free the Science

ECS at 115

I hope most of you have heard of ECS’s initiative to Free the Science. Our goal is to make our high quality, peer-reviewed research in the ECS Digital Library freely available to everyone. That means authors can publish for free and anyone, anywhere, can read papers, abstracts, or proceedings without a subscription. We think it will revolutionize the progress made in our niche of science and we hope it will set an example for other publishers, especially those that are nonprofit societies, to pursue a more robust open access business model.

As we celebrate our 115th anniversary this year, Free the Science couldn’t be more important. The research that YOU do has the ability to solve some of the world’s most pressing issues from energy independence and clean water, to safety and medical technology. We don’t think it’s too bold to say that our science can save lives and ensure our planet’s sustainability. And that’s why, more than ever, we must work together to Free the Science.

But our initiative to Free the Science is hardly free. While we want to open access to science there is a cost to producing peer-reviewed research. It takes time, money, and know-how to disseminate quality scientific research. After 115 years in the field of scholarly communications, ECS has the knowledge and bandwidth to implement such an initiative, but we need the support of our membership to make it happen.

Darwin“The evidence is incontrovertible. Global warming is occurring.” “Climate change is real, is serious and has been influenced by anthropogenic activity.” “The scientific evidence is clear: Global climate change caused by human activities is occurring now, and is a growing threat to society.” The Conversation

As these scientific societies’ position statements reflect, there is a clear scientific consensus on the reality of climate change. But although public acceptance of climate theory is improving, many of our elected leaders still express skepticism about the science. The theory of evolution also shows a mismatch: Whereas there is virtually universal agreement among scientists about the validity of the theory, only 33 percent of the public accepts it in full. For both climate change and evolution, skeptics sometimes sow doubt by saying that it is just a “theory.”

How does a scientific theory gain widespread acceptance in the scientific community? Why should the public and elected officials be expected to accept something that is “only a theory”? And how can we know if the science behind a particular theory is “settled,” anyway?
