Bill Nye the Science Guy drops some science on the Patriots and takes the opportunity to deliver a message on climate change.
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 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.

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?
The ECS Conference on Electrochemical Energy Conversion & Storage with SOFC-XIV convening in Glasgow, Scotland at the Scottish Exhibition and Conference Centre from July 26-31, 2015 is the first of a series of planned biennial conferences in Europe by ECS on electrochemical energy conversion/storage materials, concepts, and systems.
We are creating a forum where scientists and engineers can come together and discuss fundamental advances and engineering innovations.
Abstracts are due February 20, 2015

The lead organizers of this conference are among the top researchers in their respective fields. We wanted to take a moment to introduce them to you:
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!
“Comprehensive scientific assessments of our current and potential future climates clearly indicate that climate change is real, largely attributable to emissions from human activities, and potentially a very serious problem.” This is pulled from a public policy statement originally written in 2004 by the American Chemical Society.
Eighteen scientific societies signed on to a similar American Association for the Advancement of Science statement affirming the consensus scientific view on climate change in 2009. According to the California Governor’s Office of Planning and Research, at least 200 worldwide scientific organizations now formally hold the position that climate change has been caused by human action.
The International Panel on Climate Change (IPCC) was set up in 1988 to assess global warming and its impacts. Recently, the panel released a major report, capping its latest assessment, a mega-review of 30,000 climate change studies that establishes with 95-percent certainty that nearly all warming seen since the 1950s is due to human activity. More than 700 of the world’s top climate scientists and 1,729 expert reviewers from more than 70 countries participated in the report process.
New technology developed by researchers at the University of Michigan has been designed with the intention of preventing fires caused by lithium-ion battery malfunctions.
Researchers are making this possible by creating an advanced barrier between the electrodes in the lithium-ion battery. The barrier is made with nanofibers extracted from Kevlar – the material known for its use in bulletproof vests. The Kevlar nanofibers stifle the growth of metal tendrils that can become unwanted pathways for electrical current.
“Unlike other ultra strong material such as carbon nanotubes, Kevlar is an insulator,” said Nicholas Kotov, the Joseph B. and Florence V. Cejka Professor of Engineering. “This property is perfect for separators that need to prevent shorting between two electrodes.”
Short-circuiting happens in these batteries when holes in the membranes are too big and dendrites poke through to the membrane. They create a path for electrons within the battery, shorting it out.
