United States President John F. Kennedy sent a powerful message to the country in his speech at Rice University in1962, “We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are unwilling to postpone, and one we intend to win.”

History has shown that it was not necessary to go to the Moon to win Kennedy’s challenge. His primary goal was to elevate U.S. national security during the Cold War when the Soviet Union was advancing as a world power and showing signs of superiority in their space program. The U.S. put a man on the Moon in 1969, but far more important was the spirit of innovation that was created, leading to world-changing new technologies in security, communications, and transportation, which was the true win.

Kennedy understood the importance of innovation and risk taking to the success of a nation and his speech permanently implanted this message into the ideal of science and the role it plays in advancing mankind. He continues to stimulate progress because in his words, “there is new knowledge to be gained … and used for the progress of all people.” It is amazing how Kennedy’s influence has prevailed. In a recent ECS podcast with Steven Chu,* the former U.S. Secretary of Energy and 1997 Nobel Prize winner said, “As a scientist, you better be an optimist … half the science I try to do is really shoot for the Moon.”

Applying a tiny coating of costly platinum just 1 nanometer thick—about 1/100,000th the width of a human hair—to a core of much cheaper cobalt could bring down the cost of fuel cells.

This microscopic marriage could become a crucial catalyst in new fuel cells that use generate electricity from hydrogen fuel to power cars and other machines. The new fuel cell design would require far less platinum, a very rare metal that sold for almost $900 an ounce the day this article was produced.

“This technique could accelerate our launch out of the fossil-fuel era,” says Chao Wang, an assistant professor of chemical and biomolecular engineering at Johns Hopkins University and senior author of a study published in the journal Nano Letters.

“It will not only reduce the cost of fuel cells,” Wang says. “It will also improve the energy efficiency and power performance of clean electric vehicles powered by hydrogen.”

A new quantum material mimics a shark’s ability to detect the minute electric fields of small prey.

Such a technology might be used to study ocean organisms and ecosystems and to monitor the movement of ships for military and commercial maritime applications, says Shriram Ramanathan, professor of materials engineering at Purdue University. “So, it has potentially very broad interest in many disciplines.”

The material maintains its functional stability and does not corrode after immersion in saltwater, a prerequisite for ocean sensing. Surprisingly, it also functions well in the cold, ambient temperatures typical of seawater.

Earlier this year, a group in the ECS Corrosion Division mobilized a push to honor the work and memory of the late Hugh Isaacs, who passed away on December 5, 2016. Isaacs had been an ECS member since 1967 and is recognized as an ECS fellow.

The group unified donors among Isaacs’s family, friends, and colleagues in an effort to commemorate all he contributed as an impassioned champion of electrochemical science and engineering, and as a preeminent figure in the corrosion community. Isaacs’s widow, Sheila Isaacs, contributed an anchor gift that helped make their endeavor possible.

Their work culminated in the creation of the Hugh Isaacs Collection, a sponsored collection containing all 45 of the articles Isaacs published in the Journal of The Electrochemical Society. The collection is currently available in the ECS Digital Library. Read now!

Mapping Nanoscale Ion Transport
Lushan Zhou

Transport of ions at small length scales plays critical roles in almost all physical and biophysical processes. Investigation of local ion transport properties requires tools for direct visualization of spatially distributed ions at interfaces. Scanning ion conductance microscopy (SICM), a scanned nanoscale pipette, allows high resolution non-contact topography
imaging of samples bathed in electrolyte and therefore is well-suited for nanoscale ion transport studies. Read more.

A new flexible, transparent electrical device inspired by electric eels could lead to body-friendly power sources for implanted health monitors and medication dispensers, augmented-reality contact lenses, and countless other applications, researchers report.

The soft cells—made of hydrogel and salt—form the first potentially biocompatible artificial electric organ that generates more than 100 volts. It produces a steady buzz of electricity at high voltage but low current, a bit like an extremely low-volume but high-pressure jet of water. It could be enough to power a small medical device like a pacemaker.

While the technology is preliminary, Michael Mayer, a professor of biophysics at the Adolphe Merkle Institute of the University of Fribourg in Switzerland and the paper’s corresponding author, believes it may one day be useful for powering implantable or wearable devices without the toxicity, bulk, or frequent recharging that come with batteries.

A team of researchers from MIT recently demonstrated a new electrochemical method to study thermodynamic processes in an ultra-high temperature molten oxide. In an effort to find new insights into the thermodynamic properties of refractory materials, researchers have developed a container-less electrochemical method to study thermodynamic properties of materials like aluminum oxide, which melts at temperatures above 2,000 degrees Celsius.

The finding were reported in the open access paper, “Electrochemical Study of a Pendant Molten Alumina Droplet and Its Application for Thermodynamic Property Measurements of Al-Ir,” which was recently published in the Journal of The Electrochemical Society.

“We have a new technique which demonstrates that the rules of electrochemistry are followed for these refractory melts,” says senior author Antoine Allanore, an associate professor of metallurgy and member of ECS. “We have now evidence that these melts are very stable at high temperature, they have high conductivity.”

Below is an excerpt from an article published in the winter 2017 edition of Interface.

The explosive progress of information technology and 5th generation communication technology enables the introduction of the Internet of Things, where the network of physical objects—devices, vehicles, and buildings embedded with sensors, electronics, software, and network connectivity—permits these physical objects to collect and exchange data. The use of dielectric materials in sensors for a multitude of applications such as self-driving cars has made the dielectric science and technology research even more significant than before.

More than seventy years ago, in 1945, it all started with establishing the Electric Insulation Division in ECS to offer an interdisciplinary forum to discuss the science of the materials used for electrical insulation in power transmission. With the advancement of technology, when integrated circuits became popular, the division became the Dielectrics and Insulation Division in 1965. In 1990, it became the Dielectric Science and Technology Division due to extensive growth in electronic manufacturing technology. Today, the division still provides a strong interdisciplinary research environment.

In this issue of Interface we have focused on some of the current topics that are an integral part of current and future technologies.
