A collaborative group of six researchers from Stony Brook University and Brookhaven National Laboratory are using pioneering x-ray techniques to build a better and more efficient battery.

The researchers—four of whom are active ECS members, including Esther Takeuchi, Kenneth Takeuchi, Amy Marschilok, and Kevin Kirshenbaum—have recently published their internal mapping of atomic transformations of the highly conductive silver matrix formation within lithium-based batteries in the journal Science.

(PS: You can find more of these scientists’ cutting-edge research by attending the 228th ECS Meeting in Phoenix, where they will be giving presentations. Also, Esther Takeuchi will be giving a talk at this years Electrochemical Energy Summit.)

This from Stony Brook University:

In a promising lithium-based battery, the formation of a silver matrix transforms a material otherwise plagued by low conductivity. To optimize these multi-metallic batteries—and enhance the flow of electricity—scientists need a way to see where, when, and how these silver, nanoscale “bridges” emerge. In the research paper, the Stony Brook and Brookhaven Lab team successfully mapped this changing atomic architecture and revealed its link to the battery’s rate of discharge. The study shows that a slow discharge rate early in the battery’s life creates a more uniform and expansive conductive network, suggesting new design approaches and optimization techniques.

U.S. Begins Utilizing Hydro Power (Video)

The United States has focused the majority of its solar energy efforts on solar and wind power for the grid. For the first time ever, wave power is being utilized in the U.S. to power homes off the coast of Hawaii.

Waves are being turned into electricity through the Azura prototype, which captures the complex motion of waves to more efficiently capture wave movement for better electricity generation.

The device, which was deployed last month, will be monitored for one year to measure effectiveness and efficiency. If all goes as well as researchers predict, a larger version will hit the seas in 2017.

Researchers from Cornell University are focusing their efforts on developing superconductors that can carry large energy currents, thereby expanding the possible benefits that can be produced by high-temperature superconductors.

In order to coax the superconductors to carry these large currents, researchers have previously bombarded materials with high-energy ion beams. This approach increased the current density carried, but still left the question of what is actually happening in this reaction.

Thanks to the technology of the scanning tunneling microscope (STM), the researchers can now understand what is happening at the atomic level. (German physicist, Gerd Binnig, won the Nobel Prize in Physics in 1986 for the invention of the scanning tunneling microscope He gave the ECS Lecture at the 203rd ECS Meeting in Paris, France.)

ECS Masters – Esther Takeuchi

“Scientific discovery is a marathon, not a sprint. Sometimes you’re running faster or slower, but you always have to keep going.”
Esther Takeuchi

Esther Takeuchi was the key contributor to the battery system that powers life-saving cardiac defibrillators.


She currently holds more than 150 U.S. patents, more than any other American woman, which earned her a spot in the Inventors Hall of Fame. Her innovative work in battery research also landed her the National Medal of Technology and Innovation in 2008.

IBM’s New Chip Quadruples Capacity

In recent years, the semiconductor industry has struggled to keep up with the pace of the legendary Moore’s Law. With the current 14-nanometer generation of chips, researchers have begun to question if it will remain possible to double transistor density every two and a half years. However, IBM is now pushing away the doubt with the development of their new chip.

The new ultra-dense chip hosts seven-nanometer transistors, which yields about four times the capacity of our current computer chip. Like many other researchers in the field, IBM decided to move away for the traditional and expensive pure silicon toward a silicon-germanium hybrid material to produce the new chip.

The success of the high-capacity chip relies on the utilization of this new material. The use of silicon-germanium has made it possible for faster transistor switching and lower power requirements. And did we mention how impossibly small these transistors are?

Chemical Bonds On-Demand

Until now, the idea of controlling reactions with the light from lasers was only theoretical. However, new research shows that a laser pulse has the ability to control the formation of a molecular bond between two atoms.

Due to this new development, researchers can now control the path of the chemical process with extreme precision.

This from APS Physics:

For the first time, researchers demonstrate the coherent control of the reaction by which two atoms form a molecule. The achievement—coupled with other photocatalyst tools—could potentially lead to a chemical assembly line, in which lasers slice and weld molecular pieces into a desired end product.

Unique IdentifierBack in March, I wrote a post gushing about the utility of ORCID identifiers. For those of you who haven’t seen it you can find it here, and for those of you who have seen it, but have yet to sign up, it’s probably time to think about it!

Because everyone likes lists, here’s ECS’s top 5 reasons to register for your ORCID ID today:

1. Differentiate yourself.
Think about how many “J. Smith”s there are in the world. ORCID lets you stand out from the crowd and ensures that your research is appropriately attributed.

2. Names change, affiliations change, e-mail accounts change.
There is little about an individual’s research profile that is static – people find new jobs, change names, or just switch from Outlook to Gmail. No matter what the change is, your professional contacts will be able to find your current information—even if they’re reaching out to you about a paper you wrote four jobs ago or in grad school.

We’re one step closer to atomic layer transistors due to recent research by a team of McGill University and Université de Montréal researchers. The new findings are the result of multidisciplinary work that yielded evidence that the material black phosphorus may make it possible to pack more transistors on a chip.

Researchers from McGill University joined with ECS’s Richard Martel in the Université de Montréal’s Department of Chemistry to examine if black phosphorus could tackle the prominent issue in the electronics field of designing energy-efficient transistors.

Similar to graphite, black phosphorus can be separate easily into single atomic layers to allow for thin transistors. When researchers are able to produce thinner transistors, they are also more efficient.
