Doctors have various ways to assess your health. For example, they measure your heart rate and blood pressure to indirectly assess your heart function, or straightforwardly test a blood sample for iron content to diagnose anemia. But there are plenty of situations in which that sort of monitoring just isn’t possible.

To test the health of muscle and bone in contact with a hip replacement, for example, requires a complicated – and expensive – procedure. And if problems are found, it’s often too late to truly fix them. The same is true when dealing with deep wounds or internal incisions from surgery.

In my engineering lab at Tufts University, we asked ourselves whether we could make sensors that could be seamlessly embedded in body tissue or organs – and yet could communicate to monitors outside the body in real time. The first concern, of course, would be to make sure that the materials wouldn’t cause infection or an immune response from the body. The sensors would also need to match the mechanical properties of the body part they would be embedded in: soft for organs and stretchable for muscle. And, ideally, they would be relatively inexpensive to make in large quantities.

Lithium-ion battery safety has been a hot topic in the scientific community in light of instances of the Samsung Galaxy Note 7 bursting into flames. In order to address these concerns, scientists must first better understand exactly what is causing these safety concerns. In order to do that, a team from the University of Michigan is looking inside the batteries and filming growing dendrites – something the researchers cite as one of the major problems for next-gen lithium batteries.


The study focused primarily on lithium-metal batteries, which have the potential to store 10 times more energy that current lithium-ion batteries. However, researchers believe that issues with dendrites cannot be amended, the future of the Li-metal battery will not be as limitless as some believe.

“As researchers try to cram more and more energy in the same amount of space, morphology problems like dendrites become major challenges. While we don’t fully know why the Note 7s exploded, dendrites make bad things like that happen,” said Kevin Wood, postdoctoral researcher and ECS student member. “If we want high energy density batteries in the future and don’t want them to explode, we need to solve the dendrite problem.”

ImmigrationNobel laureates are speaking out on immigration policies, highlight their own status as immigrants and the importance of open boarders to advance science. Of the year’s Nobel Prize winners, six affiliated with U.S. universities are immigrants.

Across the globe, many countries have been discussing and legislating new immigration policies that make it more difficult to travel from place to place. These immigration conversations have led to moves such as the UK’s Brexit, Hungary’s attempts to keep “outsiders” from crossing its boarder, and U.S. presidential nominee Donald Trump’s plan to build a wall on the U.S./Mexico border.

Research conducted in late 2015 revealed that as immigration policies harden globally, scientists in the developing world are caught in the crosshairs, causing innovation and research to suffer.

“I think the resounding message that should go out all around the world is that science is global,” James Fraser Stoddart, a winner of the Nobel Prize in Chemistry and a professor at Northwestern University, who was born in Scotland, told The Hill. “It’s particularly pertinent to have these discussions in view of the political climate on both sides of the pond at the moment…. I think the United States is what it is today largely because of open borders.”

John B. Goodenough

Goodenough was recently named Fellow of ECS at the PRiME 2016 meeting.

John B. Goodenough is recognized internationally as one of the key minds behind the development of the lithium-ion battery; a device that is used to power a huge percentage of today’s electronics and a technology that helped shape the technological frontier.

In a recent interview with the BBC’s Today program’s John Humphrys, the man who helped make the mobile phone possible discusses battery safety in light of exploding Samsung batteries, the Nobel Prize, and his why he doesn’t like cellphones.

“I see the students running around, punching these little tablets, and not talking with one another,” Goodenough says. “I see people going out to dinner and not talking to their partner, rather sitting there talking to someone on their phone, I say, ‘Well, that’s not the way to live.’ Technology is morally neural, it’s what we do with technology that judges us.”

ECS shows its vision for the future of academic publishing

Open AccessECS is celebrating Open Access Week this year by giving the world a preview of what complete open access will look like. From October 24th through October 30th, we are taking down the paywall to the ECS Digital Library, making over 132,000 scientific articles and abstracts free and accessible to anyone.

Eliminating the paywall during Open Access Week is a preview of ECS’s Free the Science initiative; a business-model changing plan with the goal of making the entire ECS Digital Library open access by 2024. ECS believes that the opening and democratizing of this information will lead to rapid advances in discoveries ranging from renewable energy to clean water and sanitation.

“ECS has one core goal: to disseminate this scientific research to the broadest possible audience without barriers,” says Mary Yess, ECS Deputy Executive Director and Chief Content Officer. “The research of our authors has the ability to address some of the most critical issues across the globe, and we believe paywalls should not impede progress.”

231st ECS MeetingTopic Close-up #3

Symposium IO4: Solid-Gas Electrochemical Interfaces 2 – SGEI 2

Symposium Focus is on electrochemistry in many solid-state electrochemical processes and devices (such as gas electrolysis, fuel cells, ionic separation membranes, metal-air batteries, and gas sensors) occurs within a localized region near the interface between the reactant gas and one or more solid phases. During the last 10-15 years, it has become increasingly clear that the composition, structure, and/or properties of materials within this localized region deviate substantially from the bulk material(s) comprising the electrocatalyst.

Examples include stoichiometry variations in the vicinity of a three-phase boundary (TPB), enhanced activity near solid-solid heterointerfaces, cation segregation associated with surface reconstruction, and cation stratification/interdiffusion or secondary phase precipitation near gas-solid or solid-solid interfaces. Recent advances in both analytical techniques and modeling are beginning to shed new insights into these local variations in structure/composition, and the role they play in governing local rates.

These include new in situ experimental methods that probe the thermodynamic state of the solid bulk and surface under finite driving force, scanning probe and other methods that can spatially resolve local variations in conductivity, structure, composition, and reaction rates, and modeling methodologies that consider heterogeneity and local properties, including ab initio methods that consider variations in structure/composition at surfaces.

Kroto in Nanoland

Harry KrotoPioneering nanocarbons researcher Harry Kroto passed away on April 30, 2016 at the age of 76. A giant among giants, Kroto made an immense impact on ECS and its scientific discipline as well as the world at large. Because of this, an upcoming focus issue of the ECS Journal of Solid State Science and Technology honors the memory of Kroto, who is best known for his role in discovering that pure carbon can exist in the form of a hollow soccer ball-shaped molecule named the “buckminsterfullerene” (“buckyball” for short).

“Harry Kroto’s passing is a great loss to science and society as a whole,” says Bruce Weisman, guest editor of the focus issue. “He was an exceptional researcher whose 1985 work with Rick Smalley and Bob Curl launched the field of nanocarbons research and nanotechnology.”

Subsequent studies of carbon nanostructures have uncovered scientific phenomena and developed novel materials that promise myriad applications ranging from energy harvesting and drug delivery to high performance composites. Research in this field continues to fill the pages of scholarly journals, making possible innovations that were not even conceived before the seminal work.
