Researchers around the world are in a scientific race to develop a near-perfect lithium-ion battery, and a startup from the Massachusetts Institute of Technology (MIT) may have just unlocked the secret.

In 2012, Qichao Hu founded SolidEnergy – a startup that grew out of research and academics from MIT. Qichao started with battery technology that he and ECS member Donald Sadoway developed.

Now, the company is claiming to have built a lithium-ion battery that could change battery technology as we know it.

Dr. Yossef Elabd, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, has developed two fuel cell vehicle platforms for both present day enhancements and future innovation.

The Electrochemical Society’s Yossef A. Elabd is using electrochemical science to work toward global sustainability with his new advancements in fuel cell car technology.

Elabd, an active member of ECS’s Battery Division, has developed two fuel cell vehicle platforms for both present day enhancements and future innovation – focusing not only on the science, but also the environment.

“I just want to drive my car with water vapor coming out the back of it,” Elabd said.

With this new technology and initiatives such as the ECS Toyota Young Investigator Fellowship, Elabd’s statement may become an achievable reality for many people in the near future.

The idea of the fuel cell vehicle is every environmentalist’s dream, but the current issues deal with the sustainability of the vehicle. The current fuel cell car uses a proton exchange membrane (PEM) electrolyte for its platinum-based electrodes.

Science can be a strange and wondrous world of extraordinary innovation and unbelievable discovery. Now, one of our favorite scientific innovations has made its return: the cyborg cockroach.

As you may remember, ECS Board Member and Senior VP Dan Scherson once co-authored a paper that detailed how a cyborg cockroach can generate and transmit signals wirelessly. (You can check paper out here – it’s open access!)

Now cyborg cockroaches are making their way back into science with a new study that uses the roaches to pick up sounds with small microphones and seek out the source of that sound.

The purpose of this development is to help emergency personnel find and rescue survivors in the aftermath of an accident.

“The unique and longer-term part of our OA plan is to “Free the Science™“: to provide all ECS content at no cost to anyone—no fees for authors, readers, and libraries.”

Published in the latest issue of Interface.

The models of scientific communication and publication—which have served us all so well for so long—are no longer fully meeting the spirit of the ECS mission, may not be financially viable, and are hurting the dissemination of the results of scientific research.

The future of Open Access (OA) can change not only scholarly publishing, but can change the nature of scientific communication itself. OA has the power to more “evenly distribute” the advantages currently given to those who can easily access the outputs of scientific research.

ECS has long been concerned with facilitating that access, and our mission has been to disseminate the content from within our technical domain, as broadly as possible, and with as few barriers as possible. To accomplish this, we have maintained a robust, high-quality, high-impact publishing program for over 100 years.

Several years ago, ECS started taking a serious look at the challenges facing us in fulfilling our mission, specifically with respect to our publishing program. The challenges—faced by others in publishing, to a greater or lesser degree—are many and have become increasingly sever.

When a commercial scientific publisher is taking a 35% net profit out of the system, compared with under 2% by ECS, something is not only wrong, but it is clear that some publishers will do anything and everything they can to keep maintaining that level of profit. For many, journal publishing has indeed become a business.

Materials scientists have developed a new technique that could provide a simpler and more effective way to produce electrode materials for batteries and supercapacitors, which could potentially lead to devices with improved energy and power densities.

The researchers have unlocked this new battery technology by exposing tiny bits of graphene to a process that is very similar to deep-frying.

Prior to this development, scientists had difficulty using graphene in electrodes due to the difficulty encountered when processing the material. However, the researchers out of Yonsei University have learned how to harness the material’s electrical and mechanical properties while retaining its high surface are by using an alternative technique.

You may remember the classic alkali metal explosion demonstration in one of your early chemistry classes. Many educators use this experiment to show the volatile power of chemistry. The thought was that the unstable reaction was caused by the ignition of hydrogen gas, but scientists in the Czech Republic have found new information behind this classic demonstration by using high-speed video.

The researchers began investigating the science behind this experiment by dropping a sodium-potassium alloy droplet into water. From there, they recorded the explosion with a high-speed camera that is capable of capturing 10,000 frames per second.

Of course, there’s a video.

An article by Christopher D. Taylor in the latest issue of Interface.

In the late 20th century, computer programs emerged that could solve the fundamental quantum mechanical equations that control the interactions of atoms that give rise to bonding. These tools, first applied to molecules and bulk solid materials, then began to be applied to surfaces and, in the early 21st century, to electrochemical environments. Commercial and open-source programs are now readily available and can be used on both desktop and high-performance computing platforms to solve for the electronic structure of a given configuration of atomic centers (nuclei) and, in so doing, provide the basis for determining a whole host of properties, including electronic and vibrational spectra, electrical moments such as the system dipole, and, most importantly, the energy and forces on the atoms. Other derived properties include the extent to which each atom is charged and bond-orders, although to compute these latter properties one of a variety of methods for dividing up and quantifying the electron density associated with each atom must be selected.

The physics behind these codes is complex, and, challengingly, has no rigorous analytical solution that can be obtained within a finite allotment of time. Thus, the computer programs themselves take advantage of approximations that allow for a feasible solution but, at the same time, constrain the accuracy of the result. Nonetheless, solutions can usually be reliably obtained for model systems representing materials, interfaces, or molecules that do not exceed thousands, and, more realistically, hundreds of atoms. Given that system sizes of hundreds or thousands of atoms amount to no more than the smallest nanoparticle of a substance, the question arises: What can atomistic simulations teach us about corrosion?

On January 27, 1880, Thomas Edison received the historic patent embodying the principals of his incandescent lamp that paved the way for the universal domestic use of electric light.

On this very day in the year 1880, Thomas Edison was granted a patent for the electric lamp, which gave light by incandescence.

While the first electric carbon arc lamp was invented by Sir Humphrey Davey of England in 1801, it wasn’t until Edison’s discovery in 1880 that we got the longer lasting electric lamp that changed the way we live.

Edison was one of the original members of The Electrochemical Society, joining the organization in 1903 – just one year after it was established. Early members such as Charles Burgess recall attending ECS meetings at Edison’s home in the early days of the Society.

On his years of research in developing the electric light blub, Edison was quoted in “Talks with Edison” by George Parsons Lathrop in Harpers magazine on February of 1890. He had this to say:

“During all those years of experimentation and research, I never once made a discovery. All my work was deductive, and the results I achieved were those of invention, pure and simple.”

Since the Thomas Edison’s days in the Society, ECS has been working to promote technological innovation and inspire scientists from around the world. Join some of the greatest scientific minds in electrochemical and solid state science and technology by becoming a member today!
